I quite literally went through the entire video thinking that your had 100 or 200 subscribers, only to find out you had 33. This was actually a really good video, if I HAD to give you a suggestion, I would edit out a couple of pauses, but other than that it was pretty good.
I am from Brazil and here we are not allowed to use calculators in High School at all. So my first contact with a graphic calculator was in the engineering school, though the HP is more popular among the engineering students in Brazil because TI doesn't sell their products here, which makes me wonder why? Since it is hard to find, TI products are quite "exotic" and extremely expensive. The TI-Nspire CX II CAS costs around 2k BRL (around 366 USD). I recently bought a TI-Nspire CS II just for curiosity and because I wanted to test its features with bbc micro:bit and the support for python language, but honestly it is not that good, there is no reason for this calculator to be so expensive. And I agree with you, modern phones and tablets can do way better than those calculators and some company is missing the chance to have them adapted to schools just like the calculators once were.
O problema de usar smartphones ou tablets é que nas provas não poderiam ser usados, mas realmente essas calculadoras poderiam facilmente ser substituídas por um aplicativo e rodariam muito melhor. A própria HP tem um aplicativo na Play Store da HP Prime e custa R$70, bem melhor do que pagar R$1000 na calculadora física. E tem a HP Prime Lite também que tem menos funções mas é grátis.
@@claudioantoniosuzukideoliv594 eu pensava que o app HP Prime Pro fosse mais caro. Eu tenho instalado nos meus smartphones o app HP Prime Lite e mal e mal uso ele. Tenho outros apps instalados, emulando desde antigas calculadoras HP até outras bem recentes, incluindo a HP 50g. Eu tenho a HP 50g física a alguns anos e me acostumei muito bem com ela. Por isso não gosto da HP Prime. Mas claro que existem méritos na HP Prime, na exata medida em que a HP 50g não teve uma sucessora. E aí a qualidade da resolução da tela é um abismo, bem como a velocidade. Fora outros pequenos detalhes, como não usar a simbologia de graus, minutos e segundos. Mas como me acostumei co a HP 50g, considero que no meu caso não vale a pena usar outra. A não ser quando a minha pifar... Aí, não podendo usar o smartphone, serei obrigado a comprar outra. Mas é importante frisar que a HP Prime não é sucessora da HP 50g, pois não usa nativamente RPN e nem RPL.
Which HP? The Prime I assume? A G2, I hope. :) What flavor of engineering are you studying? I'm a retired Controls Engineer myself. These days I collect old calculators. Just not many '83s and '84s. I'll pick them up if I come across one at Goodwill (a thrift store here in the States). The last one that I bought was $1.99 (I think. It might have been $3.99). I did score four TI-92 Plus calculators for about $15 each (that's pretty cheap, and they all work) and a TI-95. And I have a Texas Instruments LCD Programmer coming in. It's TI's answer to the HP-16C. And a Casio fx-890P, in the box, nearly mint. Have you seen the SwissMicro calculators? Those, and the HP-15C Collector's Edition are simply fantastic. I had to buy a HP-15C for my electronics courses in college in the 80's. Hands down my favorite calculator. And I have a brand new HP-15C CE that I use daily. Life is good. :) And we have something in common, I didn't use a calculator in high school either since you could literally buy a good used car for what a calculator cost back then. Slide rules on the other hand tended to be cheap, and I still have mine from high school. But for the most part I just used the tables in the back of the math books. Those were free. :)
Hey @@MrWaalkman thanks for sharing. When I was a student in electronics engineer course, the most used HP was the 50G. Nowadays, I believe the students use prime more. Since 2020, I return to school for a second degree in computer engineering, but so far I haven't been feeling the need to buy any other calculator, 50G is still very good at this job lol. The TI N-spire was a matter of curiosity, I wanted to see how it might be used in small-funny projects, like controlling an Arduino or something else. I've never heard about the SwissMicro, Brazil is a pretty closed market, if the company doesn't manufacture the product here it would be way hard to buy, since the importation taxes are huge. Thanks for the tip though, I am for sure going to checking it out. My old sister lives in Switzerland, perhaps I can get another toy for Christmas, lol. I hope you have a great day!
When I was growing up, the TI-83 Plus was the standard in schools and it hasn't changed a bit since then but still find it at Wal-Mart not simply costing the same, but actually a little MORE than mine cost back in 1998. In fact, it costs just $20 less than a TI-Nspire CX2 CAS which I just ordered because I'm doing a lot more math now, lol.
Great topic to be opening up. Clearly a lot of work needs to be done in this space. Historically, though, there have been numerous instances where a "de facto" standard has emerged, and a small number of industry players have been able to corner the market. In the last 50 years, Microsoft is a clear example with it's MS-DOS, now Windows, and the way Bill Gates ingratiated his product into IBM PCs is a worthwhile example to study. Calculators for education is what I would term a "vertical" market and one has to consider why HP have decided not to compete in that field anymore. Good luck with your studies. You are opening up a very salient point well worthy of further probing and opening up.
My friend and I use HP Prime calculators as engineering majors. They are much nicer than the TI variants and we help each other with any troubleshooting. It is WAY worth the extra google search to have all of the extra features and a touchscreen.
@@cardboard952 Check out the TI-92 Plus. Basically it's the same calculator as the 89 on the inside, but with a much nicer screen. And I just got mine for $16.99 with free shipping.
I'm a retired Controls Engineer, not much need for calculators these days. :) What flavor of engineer are you pursuing? And the Prime is probably the best out there today. Do you have the G2 version?
@@MrWaalkman I'm in my senior year as a mechanical engineering major and I have the G2. One of my friends has the G1 but he updated the software. Also, much respect for you. Controls engineering is not an easy discipline!
@@brandonshaffer5295 Great to hear that the Primes are out there being used. :) And thanks! I come from the early days of PLCs, and because it is such an oddball discipline, it was nearly impossible to teach for it in university. These days there's Mechatronics which is a step in the right direction. But it still boils down to you either get it or you don't. So what you see in Controls, that you don't see anywhere else (that I'm aware of), is a relaxation of the rules because good (any) Controls people are hard to find. And anyone who's invested in a 4 - 5 years in a EE degree isn't going to chase conveyors in all parts of the world for the rest of their life. This leads to a group that is made up of about 50% EEs, and 50% "random citizens with curious skills". :) I'm from the latter 50%, getting my start when as a construction electrician while on a job at Goodyear in Lincoln, Nebraska. What happened was that the engineers wouldn't fix a problem that was forcing the operators to have to clean out the "Whale Tail" (about 500 pounds of hot smoking rubber) from the mouth of the extruder. This was happening about six times a day and it was killing the operators. So I stayed late one night and fixed the problem with the PLC on the Berstorff Extruder/Calender (that's spelled correctly) line. After Goodyear finished chewing my butt out the next day they gave me a field promotion to PLC programmer. No extra money, just the promotion. :) BTW, that was the very first time that I programmed a PLC. Seemed obvious to me... The PLC that it used was a GE Series Six (S6), which was a rarity. Once I left Nebraska, I figured that I would never see one again, let alone program one, but along came Saturn and nearly every PLC in the place was a GE Series Six. While working in Kansas City I ran into a company who was looking for a S6 guy while I was looking for some part time work to earn a bit of extra cash for one of those new-fangled things called a "Personal Computer". The lady at the company asked me out of the blue if I knew how to program a S6, and I replied "Why yes, doesn't everybody?" Or something like that. :) I was one of two people other than the GE guys who had previous experience on the S6 during the construction of the General Assembly building. The other one was my old partner Neil, who was a few credits shy of a degree. Saturn snapped us up and the rest is history. This was back in the days where we would measure the memory of a PLC in kilobytes. The standard package from GE having 4k of programming space. While complaining to a GE engineer that the memory was too small, and that we were going to have to upgrade to 8k, he mentioned that there really wasn't a big difference between the boards. Ding, ding, ding! I took a 4k and a 8k board out and compared them side by side and the only difference was that jumper J7 was removed on the 4k board. One jumper later, and the board was rocking the "Big 8k". General Electric was not amused... :) These days I am mentoring a couple of MEs in the dark arts of PLC programming for a project that is headed back to Antarctica. The projects' name is RAID, and here is a video of the system that we are upgrading (the FRS, or "Fluid Recovery System"): ua-cam.com/video/50_3r54gIiM/v-deo.html You can see the old PLC at the 2:58 mark of the video. Because of the low temperatures in the Antarctic, that Pelican box would have to be removed at the end of the season and stored in a warm place (relatively warm, > -40). So the entire (huge) box would be unplugged and carried back to the States. We've replaced it with trays that we made that fit into a server rack that are about the size of two pizza boxes end to end. Two of the three trays have to be stored, the third one is just for terminal strips and can freeze to death as far as we are concerned. The two unplug and get packed into a suitcase and that's that. And all of the process metering has to be removed as well (anything electronic has to be stored), which inexplicably was hard-wired to the system. We installed plugs and sockets. Just my flair for the obvious. :) Kira is the lead, and she did most of the initial CODESYS programming. Tyler has taken over for Kira (who now works remote) and will be doing the commissioning as well as the HMI programming (as seen at 2:58). Both of them are MEs (this is the only place that I have worked that the MEs outnumber the CEs). I'm doing this as a favor for a friend who worked with me at GM. I'm not too interested in the money (usually I can't be bothered to bill them), but it's nice to get out and visit from time to time. Mostly I sit back and make the occasional suggestion between naps. :) Enough rambling, enjoy your career, and poke your nose into PLC programming to see if you like it. Best of luck! :)
Damn this was a pretty wild vid that just popped up on my front page. I can definitely tell that legit effort went into this and overall a pretty good vid. In simplest terms: genuinely great. Gonna be stickin around to see what this guy cooks up next for vids that's for damn sure.
Reason graphing calculators are so slow is they are almost all running zilog Z80 CPU’s for compatibility. The Z80 was launched in the 70’s and used in home computers such as the TRS80 CoCo.
Because Ti has the monopoly of calculators that can be used in SATs in the US. Well ... now HP released the Prime but I'm not sure how well it's doing in that market.
They are that much because they can be and, as you pointed out, they are required for school so no price is too much "for the kids". Millions of folks learned all the same stuff using a pencil and graph paper. Personally, being somewhat of a luddite, I think one gets a much better feel for how all the math works if you graph it the old way. Based on the comments, there are still some places that do it that way. I've never had a ribbon cable or battery failure using a pencil.
Good video! I'm honestly thinking of getting a Raspberry pi, putting it in a case, and running the TI emulator on it. The hard part would be putting the keyboard on it, but that could be a fun hobby.
what? why would i buy a piece of tech simply because it is manufactured in texas? if the price is horrible the price is horrible, i don't care where it comes from. they aren't a struggling underdog, they literally have a monopoly over almost every educational institution in the united states, they intentionally put their standards into the educational industry knowing they would make money by having students essentially forced to buy their products, why would i have any respect for a company that does that?
TI has multiple foundries in Texas, as well as Utah and Germany. However, none of those chips is actually used in the TI-83, no version of which ever used a processor made by TI!! The current version of the TI-83 is completely Taiwanese.
Small market (only students require hand held calculators anymore) and a near monopoly of TI. It's a bit better here in Germany, where schools allow the other manufacturers (Casio and Sharp), at least for non-graphing calculators, which are still priced reasonably.
It used to be that everyone in a technical or scientific profession had some kind of scientific calculator. That's not the case any more--scientists and engineers usually don't even own a calculator. What they do is exactly what you'd expect--they've always got either a computer or a smartphone available, and for any kind of handheld computing, they'll use an app that is either free or costs less than 10 dollars, running on the phone they own anyway. So, yes, this is the result of a single company owning a captive market of students who are not allowed to use something else, and they can set their prices and not innovate much.
I'm curious if there's a community for repairing old ones, there's gotta be tons of these laying around since most people don't use them once they're out of school
In Europe, TI calculators are dominant. They’re so dominant that some countries literally have special versions of TI calculators made to their specifications to give to their students!
hi, i enjoyed your rant as i share your opinion on about the topic of the lack of performance on commercially availiable consumer market graphing calculators and fully agree with you on the motion to suggest a 'modified smartphone' (or similiar device), there is an open source project for a graphing calculator alive right now under the moniker of 'Numworks' which looks promising. however it seems to fail to close the gap in between potential and availiable performance on the graphing calculator "market" today, as for the problem of the lack of technologically modern graphing calculators i am growing desperate or frustrated with the manufacturers since their performance is disappointing especially when compared to their economical power and history of making these tools :-/ i will probably put together a custom diy "calculator" with some parts like microcontroller and tft display or something anyways just wanted to leave my two cents on the topic here as i subbed your channel, keep up the good work, thumbsup and greetings from germany
Even I could make a phone without cellular data and wifi, and the fact that Texas Instrumental can't do that shows that they own the market. They don't care that their technology is 30 years behind, it sells. It's like standard oil, the only place you could get oil was standard oil, and the only place you can get a calculator is Texas Instrumental.
En USA, texas instrument acapara el mercado a manera de monopolio, haciendo tratos con las entidades educativas forzando a ocupar Texas. En mi casio uso la Casio Classpad 2, y es muy buena, intuitiva y tiene CAS, solo como defecto es algo lenta. Pero, me va mejor que usando la texas.
The TI-83 Plus launched in 1999. The TI-83 was 1996. The TI-83 Plus has a 6MHz z80, and the TI-84 Plus CE Python has an ez80 that can reach frequencies of up to 48MHz These things are no more powerful than than an intel 80486 that launched in 1989. Going on 40 years behind the curve The TI-83 Plus is a little more powerful than a 4.77MHz intel 8088 released in 1979.
Yes my friend, your old calculator has the same technology of my TI-86 and 84 from the mid 1990s. The processor is a z80 originally launched in 1976 (1 year before I was born). I will also mention that I wasn’t allowed to use a calculator until my senior year of high school which was 1995. It pains me to see other sectors of technology move forward while calculators stagnate. This makes apps like Matlab far more useful if you choose a math heavy study.
It's at least $200 here. Most of them. And yes, my phone is a $140 Redmi Note 10 Pro with amazing performance, and can do everything these can but 1000x better. Only getting ripped off because of the test.
"Beginning with the 5.6 OS update in fall 2020, we have removed a system-level programming capability called ASM." By removing ASM you will not be able to play games I imagine so do you recommend upgrading?
just like you said, I bought it because it's acceptable in class and a phone is not. TI has (in times past) put forth a lot of effort to make it acceptable to use graphing calculators in class and to this point I am thankful (have you ever used a slide rule?); however, now they use that prestige to get big money for a low money product. like you, it was by way of force, the best choice that I was allowed to make.
No one will make a $100.00 phone without WIFI or cellular technology because there are no profit margins in it. Also, Texas Instruments has its own chip manufacturing plants and partnerships, allowing them to get chip pennies on the dollar. Also, since Texas Instruments has such a monopoly, no cellphone manufacturer would ever be able to get their device approved on exams by the school system since Texas Instruments hold so much soft power over them. The other reason, as you mentioned, is that you can't use phones since every normal phone could be used to cheat. And no phone app or app developer has the resources to create software and teacher training programs that can be used in every school district across America. It's also more than that. Texas Instruments literally works with schools and universities to help students learn the fundamentals of math education and has many resources that only they are only equipped to provide. No other company has been built from the ground up in such a way to provide such resources. Also, why fix what isn't broken? The TI-Calculator has been the only calculator used in American schools since calculators replaced the slide rule. And you don't need a powerful device to do mathematics. The only time you would need that is trying to run very complex computer algorithms and such. And PCs are already used for that. Plus we created the atomic bomb on a computer that weighed over 30 tons and was only 1-bit. But it was still far faster than humans and made an impossible task possible. And the TI-83 Plus is a lot more powerful than that computer. And keep in mind that just because a device like the TI-83+ Plus is still made today doesn't mean it hasn't undergone small under-the-hood modifications over time. So the ribbon issue may no longer be an issue on newer generations of the device. The TI-83 Plus today is still often considered one of the best calculators around.
Then you are an idiot. He didn't literally mean make a calculator out of a $100 phone without the radio chip. He meant you can just use the processor and touchscreen of the $100 phone to use in the calculators without any significant increased costs (it would only be pennies more as those processors are literally less than $5-$10 a piece). He was basically trying to prove it can be done by giving an example ($100 phone without radio chip, etc). Casio (One well known company for graphing calculators) can easily take a processor from a 10 year old phone, create a touch screen for a combined increased cost of $10-$15 per calculator and literally become the monopoly over TI (give reviewers free calculators, and schools free calculators, etc). Nowadays programming is the thing (Python especially). The calculator will become dual purpose, a graphing calculator and a programming machine. If I were a millionaire, I would take cheap current processors, cheap ram, cheap touch screens, etc and partner with desmos ( or a solid staff of 25-30 people) and create a graphing calculator with physical buttons who software (ease of use) rivals TI. Then I would pay millions for advertising (videos showing speedtests against TI calculator,s displaying programming support, etc) and donating hundreds of calculators to reviewers and thousands to top schools with documentation. I guarantee not only I'll profit tremendously but I'll become the monopoly in 10 years or less.
how about this .... for the past 50 years no can put 5 % 60 = 3 and or to type in az 60 % 5 = 3 on any calculator it iz 0.05 and or %x when in fact there are only 5 main types % x ÷ + - and each can do the same thing .... one symbol to the equation but it dont exist any where
UA-cam channel lgr has a video explaining it pretty well, I live in Mexico and I actually preferred HP prime, tho I really hate I can't share documents and programs with classmates cuz I'm the only idiot who doesn't own a TI nspire, still mine is quite faster and easier to work on. Nice video btw bro.
price is not higher because every school use TI calcs, it is high because TI pays a lot of money to schools teachers and all the related persons (very similar to how pharmacy company pays to doctors for prescribing their medicine) so that they will ONLY use TI calculators and also encourage students to use them. this is also similar to why textbooks are expensive, because publishing companies pay to schools, as bribe to adapt their textbook and students have no other choice, so basically the amount you paid on TI calculator is not all on cost of calculator itself but a most of it is spent on schools and teachers and may be govt persons.
Thanks for answering my burning question. TI N-spire CAS application for laptops is quite shit also. It looks and feels like it's from the early 2000s.
Simple. Because nobody applied and paid for certification. Graphing calculators just got basically "disallowed" here, as we will at some point switch to computer algebra systems (or back to standard scientific calculator), but Geogebra is not done with their certification yet.
The TI-83 *Plus* was released in 1999, not 1996. TI has the calculator market cornered in the US and Canada, not necessarily in other countries. See: ua-cam.com/video/zoGl8-Wc-L0/v-deo.html
Like the review I use the HP prime the new one is faster however as you mentioned the phone is just good or better. The TI calculators are using old processors by today's standard and charging much more money for even the old outdated defunct graphing calculators like the TI83 which makes no sense what so ever or why are they even being sold.
bro how, these calculators are weaker than a ESP32 and that costs like 5 GBP (consumer, even cheaper in mass production) and the SAME DAMN screen I HAVE AND ITS 11 GBP!!!
I wish the trackpad on the Nspire did not exist as it is the most annoying thing I've ever dealt with. That and they use the cheapest plastic known to man.
Wait... you can still get TI 83 Plus calculators? My interest in TI started back in 93 when I saw it in Kmarts... if I've learned anything over the years its all about creating a monopoly with text book companies
About 2% of their corporate profits of around $6.5 billion, so probably around $130 million. I’m sure the profit margin is huge. This is for calculators in total, though, most of which are simpler scientific calculators which likely have even larger profit margins than the graphing models.
You can finally download actual graphing calculators for your phone Without having to do the work around but obviously a real calculator is nicer to use. It's just ridiculous how you can get one for free on your phone or a $100 is your only other option unless you buy used
I use a HP 95lx & i LOVE so much. Its a HP Calc graph computer. I mean Lotus 123 & msdos programming. C Pascal etc. I have a 12 c HP too... RPN its like Boooooooom
thats so expensive. for those older generations, atleast here in europe, I find them for 1-5 euros in my thriftstores. like I just saw a 84 plus for 2.50 in very good condition last week and didnt even pick it up because I stuff like this often. I really didnt know they sold them as new there thats such mean way into getting people to spend on outdated tech.
Good job trying to start up on UA-cam, your biggest problem I can suggest on fixing is looking directly at the camera. It’s distracting that you aren’t looking at the camera
Your my hero I love you so much ❤ thank you so much for this amazing video titled “Why are graphing calculators so expensive?” Truly an inspiration to this generation. Although I have to critique your knowledge. The calculator was not from 96, it hit the shelves in 96 but was created in 89, it was lesser known and took a minute to become popular. Anyways just some more information, also it’s not 100$ it’s actually 102.23$ last time I checked. Those are my critiques. Anyways thanks. My 4 sons all watch your content and really enjoy it. We live in a 1 bathroom 1 bedroom house with a twin. So we stack up to the ceiling to have room. Anyways I’m just rambling on have a good afternoon.
Good video, keep it up. Teachers aren't teaching math anymore, they are teaching calculator classes. This is a cruel reality in industry as well. The Schools are given heavy support from manufacturers to promote and pimp their products and in turn it creates a ready made market of addicts that are then hooked on the devices going forward to college. The "L" word is overused in casual conversation. Try to find an alternative. You're doing a good job here by asking questions and pushing back. Keep at it.
Generally, you will see only engineers with an HP Prime. It is even more powerful than the TI-Nspire CX CASii. However, the problem with the HP Prime is you basically have to be an engineer to know how to use it. I totally agree regarding TI. The 83/84 black & white calculators have already been around for about 25 years. They shouldn’t be selling for more than $50.
I got my first graphing calculator at the tender age of 57, just for kicks. HP Prime. I printed up the 600-page user manual and am getting to know it. I am an old science teacher-- definitely not an engineer. I'm glad I made this purchase.
Yeah, TI sucks. I pretty much limit my TI purchases to either TI-8x's for friends and/or family, TI-99/4As (got plenty of those), or TI calculators with Red LEDs (although I have '74s, 66s, & 95s as well). I also have a TI-Nspire CX II that I will be putting Linux on. I just bought another HP G2 Prime brand new from Amazon for $129, so anyone who says that you can't get them, point them here. A Numworks for I think around $99, it pales by comparison to the Prime, but it makes a nice addition to my collection. There's the Zero calculator out there, but there is zero information on it. But the Prime is simply awesome. TI ought to be ashamed. BTW, I recently bought a couple of used calculators, a Sharp PC-1600K and a HP-41CX (just to name a few).
I quite literally went through the entire video thinking that your had 100 or 200 subscribers, only to find out you had 33. This was actually a really good video, if I HAD to give you a suggestion, I would edit out a couple of pauses, but other than that it was pretty good.
I actually liked the pauses as well as other details that gave this video a genuine vibe.
I am from Brazil and here we are not allowed to use calculators in High School at all. So my first contact with a graphic calculator was in the engineering school, though the HP is more popular among the engineering students in Brazil because TI doesn't sell their products here, which makes me wonder why? Since it is hard to find, TI products are quite "exotic" and extremely expensive. The TI-Nspire CX II CAS costs around 2k BRL (around 366 USD). I recently bought a TI-Nspire CS II just for curiosity and because I wanted to test its features with bbc micro:bit and the support for python language, but honestly it is not that good, there is no reason for this calculator to be so expensive. And I agree with you, modern phones and tablets can do way better than those calculators and some company is missing the chance to have them adapted to schools just like the calculators once were.
Wow, thanks for the insight from Brazil

I'll pick them up if I come across one at Goodwill (a thrift store here in the States). The last one that I bought was $1.99 (I think. It might have been $3.99).
I did score four TI-92 Plus calculators for about $15 each (that's pretty cheap, and they all work) and a TI-95. And I have a Texas Instruments LCD Programmer coming in. It's TI's answer to the HP-16C. And a Casio fx-890P, in the box, nearly mint.

Hey @@MrWaalkman thanks for sharing. When I was a student in electronics engineer course, the most used HP was the 50G. Nowadays, I believe the students use prime more.
Since 2020, I return to school for a second degree in computer engineering, but so far I haven't been feeling the need to buy any other calculator, 50G is still very good at this job lol.

I hope you have a great day!
When I was growing up, the TI-83 Plus was the standard in schools and it hasn't changed a bit since then but still find it at Wal-Mart not simply costing the same, but actually a little MORE than mine cost back in 1998.
In fact, it costs just $20 less than a TI-Nspire CX2 CAS which I just ordered because I'm doing a lot more math now, lol.
Great topic to be opening up.
Clearly a lot of work needs to be done in this space.
Historically, though, there have been numerous instances where a "de facto" standard has emerged, and a small number of industry players have been able to corner the market.
In the last 50 years, Microsoft is a clear example with it's MS-DOS, now Windows, and the way Bill Gates ingratiated his product into IBM PCs is a worthwhile example to study.
Calculators for education is what I would term a "vertical" market and one has to consider why HP have decided not to compete in that field anymore.
Good luck with your studies. You are opening up a very salient point well worthy of further probing and opening up.
My friend and I use HP Prime calculators as engineering majors. They are much nicer than the TI variants and we help each other with any troubleshooting. It is WAY worth the extra google search to have all of the extra features and a touchscreen.
just picked up a used ti 89 titanium for $35 and its honestly so good for that pricepoint
@@cardboard952 Check out the TI-92 Plus. Basically it's the same calculator as the 89 on the inside, but with a much nicer screen. And I just got mine for $16.99 with free shipping.
I'm a retired Controls Engineer, not much need for calculators these days. :) What flavor of engineer are you pursuing? And the Prime is probably the best out there today. Do you have the G2 version?
@@MrWaalkman I'm in my senior year as a mechanical engineering major and I have the G2. One of my friends has the G1 but he updated the software. Also, much respect for you. Controls engineering is not an easy discipline!
@@brandonshaffer5295 Great to hear that the Primes are out there being used. :)
And thanks! I come from the early days of PLCs, and because it is such an oddball discipline, it was nearly impossible to teach for it in university. These days there's Mechatronics which is a step in the right direction. But it still boils down to you either get it or you don't. So what you see in Controls, that you don't see anywhere else (that I'm aware of), is a relaxation of the rules because good (any) Controls people are hard to find. And anyone who's invested in a 4 - 5 years in a EE degree isn't going to chase conveyors in all parts of the world for the rest of their life.
This leads to a group that is made up of about 50% EEs, and 50% "random citizens with curious skills". :) I'm from the latter 50%, getting my start when as a construction electrician while on a job at Goodyear in Lincoln, Nebraska.
What happened was that the engineers wouldn't fix a problem that was forcing the operators to have to clean out the "Whale Tail" (about 500 pounds of hot smoking rubber) from the mouth of the extruder. This was happening about six times a day and it was killing the operators. So I stayed late one night and fixed the problem with the PLC on the Berstorff Extruder/Calender (that's spelled correctly) line. After Goodyear finished chewing my butt out the next day they gave me a field promotion to PLC programmer. No extra money, just the promotion. :) BTW, that was the very first time that I programmed a PLC. Seemed obvious to me...
The PLC that it used was a GE Series Six (S6), which was a rarity. Once I left Nebraska, I figured that I would never see one again, let alone program one, but along came Saturn and nearly every PLC in the place was a GE Series Six. While working in Kansas City I ran into a company who was looking for a S6 guy while I was looking for some part time work to earn a bit of extra cash for one of those new-fangled things called a "Personal Computer". The lady at the company asked me out of the blue if I knew how to program a S6, and I replied "Why yes, doesn't everybody?" Or something like that. :) I was one of two people other than the GE guys who had previous experience on the S6 during the construction of the General Assembly building. The other one was my old partner Neil, who was a few credits shy of a degree. Saturn snapped us up and the rest is history.
This was back in the days where we would measure the memory of a PLC in kilobytes. The standard package from GE having 4k of programming space. While complaining to a GE engineer that the memory was too small, and that we were going to have to upgrade to 8k, he mentioned that there really wasn't a big difference between the boards. Ding, ding, ding! I took a 4k and a 8k board out and compared them side by side and the only difference was that jumper J7 was removed on the 4k board. One jumper later, and the board was rocking the "Big 8k". General Electric was not amused... :)
These days I am mentoring a couple of MEs in the dark arts of PLC programming for a project that is headed back to Antarctica. The projects' name is RAID, and here is a video of the system that we are upgrading (the FRS, or "Fluid Recovery System"): ua-cam.com/video/50_3r54gIiM/v-deo.html
You can see the old PLC at the 2:58 mark of the video. Because of the low temperatures in the Antarctic, that Pelican box would have to be removed at the end of the season and stored in a warm place (relatively warm, > -40). So the entire (huge) box would be unplugged and carried back to the States. We've replaced it with trays that we made that fit into a server rack that are about the size of two pizza boxes end to end. Two of the three trays have to be stored, the third one is just for terminal strips and can freeze to death as far as we are concerned. The two unplug and get packed into a suitcase and that's that. And all of the process metering has to be removed as well (anything electronic has to be stored), which inexplicably was hard-wired to the system. We installed plugs and sockets. Just my flair for the obvious. :)
Kira is the lead, and she did most of the initial CODESYS programming. Tyler has taken over for Kira (who now works remote) and will be doing the commissioning as well as the HMI programming (as seen at 2:58). Both of them are MEs (this is the only place that I have worked that the MEs outnumber the CEs).
I'm doing this as a favor for a friend who worked with me at GM. I'm not too interested in the money (usually I can't be bothered to bill them), but it's nice to get out and visit from time to time. Mostly I sit back and make the occasional suggestion between naps. :)
Enough rambling, enjoy your career, and poke your nose into PLC programming to see if you like it. Best of luck! :)
Video production was spot
On 👍
I've always wondered why they were so expensive. I guess it's like the same situation for insulin.
Yeah, I suppose
insuline is for free in Spain, just ask for a social healthcare system.
@@alcabellog
If only it were that simple for those of us that want one...
Damn this was a pretty wild vid that just popped up on my front page. I can definitely tell that legit effort went into this and overall a pretty good vid. In simplest terms: genuinely great. Gonna be stickin around to see what this guy cooks up next for vids that's for damn sure.
I'm from El Salvador and we were obligated to use TI Calculators for engineering school. But the HP prime is way better
Reason graphing calculators are so slow is they are almost all running zilog Z80 CPU’s for compatibility. The Z80 was launched in the 70’s and used in home computers such as the TRS80 CoCo.
Yup, but at least they are using ARM in the new NSpire line.
Agreed. You made lots of sense. TI has a monopoly. Some schools use Casio as an Alternative, but majority are TI.
Because Ti has the monopoly of calculators that can be used in SATs in the US. Well ... now HP released the Prime but I'm not sure how well it's doing in that market.
You are smart. Much smarter than I was at your age, from the Economy standpoint.
The HP Prime is a much better calculator that the TI.
Is it a better selling calculator than the ti?
@@techkidwhiz No, but it is not super hard to use and thus it can used used at the college lever and beyond.
@@techkidwhiz CASIO is a better selling calculator than TI, the TI are hardly never seen, tho HP that’s a calculator
Or NumWorks, if you're in Europe.
They are that much because they can be and, as you pointed out, they are required for school so no price is too much "for the kids". Millions of folks learned all the same stuff using a pencil and graph paper. Personally, being somewhat of a luddite, I think one gets a much better feel for how all the math works if you graph it the old way. Based on the comments, there are still some places that do it that way. I've never had a ribbon cable or battery failure using a pencil.
Love it! Really spreads the word about Texas Instruments
Good video! I'm honestly thinking of getting a Raspberry pi, putting it in a case, and running the TI emulator on it. The hard part would be putting the keyboard on it, but that could be a fun hobby.
swissmicro for hp
Oh I'm also going to do the same but with a 4 inch screen xd
Love the show. The intro is amazing!
Thank you for the support Michael!
Texas Instuments manufactures its chips in Richardson, TX. They are one of the few. Keep supporting them.
what? why would i buy a piece of tech simply because it is manufactured in texas? if the price is horrible the price is horrible, i don't care where it comes from.
they aren't a struggling underdog, they literally have a monopoly over almost every educational institution in the united states, they intentionally put their standards into the educational industry knowing they would make money by having students essentially forced to buy their products, why would i have any respect for a company that does that?
TI has multiple foundries in Texas, as well as Utah and Germany. However, none of those chips is actually used in the TI-83, no version of which ever used a processor made by TI!! The current version of the TI-83 is completely Taiwanese.
Great video and sound quality
Small market (only students require hand held calculators anymore) and a near monopoly of TI. It's a bit better here in Germany, where schools allow the other manufacturers (Casio and Sharp), at least for non-graphing calculators, which are still priced reasonably.
It used to be that everyone in a technical or scientific profession had some kind of scientific calculator. That's not the case any more--scientists and engineers usually don't even own a calculator. What they do is exactly what you'd expect--they've always got either a computer or a smartphone available, and for any kind of handheld computing, they'll use an app that is either free or costs less than 10 dollars, running on the phone they own anyway.
So, yes, this is the result of a single company owning a captive market of students who are not allowed to use something else, and they can set their prices and not innovate much.
I'm curious if there's a community for repairing old ones, there's gotta be tons of these laying around since most people don't use them once they're out of school
Texas instruments are only very very much
prevalent in America , in the whole world it's basically casio
In Europe, TI calculators are dominant. They’re so dominant that some countries literally have special versions of TI calculators made to their specifications to give to their students!
hi, i enjoyed your rant as i share your opinion on about the topic of the lack of performance on commercially availiable consumer market graphing calculators and fully agree with you on the motion to suggest a 'modified smartphone' (or similiar device), there is an open source project for a graphing calculator alive right now under the moniker of 'Numworks' which looks promising. however it seems to fail to close the gap in between potential and availiable performance on the graphing calculator "market" today, as for the problem of the lack of technologically modern graphing calculators i am growing desperate or frustrated with the manufacturers since their performance is disappointing especially when compared to their economical power and history of making these tools :-/ i will probably put together a custom diy "calculator" with some parts like microcontroller and tft display or something
anyways just wanted to leave my two cents on the topic here as i subbed your channel, keep up the good work, thumbsup and greetings from germany
Even I could make a phone without cellular data and wifi, and the fact that Texas Instrumental can't do that shows that they own the market. They don't care that their technology is 30 years behind, it sells. It's like standard oil, the only place you could get oil was standard oil, and the only place you can get a calculator is Texas Instrumental.
I would postulate that to purchase a device like a cellphone minus the wireless technology would still probably run for more money than the TIs
The apps you can download on your phones and tablets will eventually make calculators obsolete.
I had my school calculator stolen and now i have to pay $126. what. the. frick. it’s insane how much they cost. nice vid
A coffee cost $5.
So a calculator is 25 coffees, less than a month.
En USA, texas instrument acapara el mercado a manera de monopolio, haciendo tratos con las entidades educativas forzando a ocupar Texas. En mi casio uso la Casio Classpad 2, y es muy buena, intuitiva y tiene CAS, solo como defecto es algo lenta. Pero, me va mejor que usando la texas.
Dude this is some mad facts keep up the good work!
Thanks for the support!
Actually they are quite cheap for what you get. Check out the prices in the 1980s 😀
me having the masculine urge to photoshop this guy with really big ears
I have an nspire cx II with ndless installed.
Cool!
i would like your OS lol
I still have my mint ti92+ and still going strong!
I had a TI 92 I accidentally crushed it in the servo press. I have a casio calculator I am using I am probably going to buy the HP.
5 years ago my brother had ATI 89. However everything All the books are designed for TI83 and TI84 calculators.
Its called monopoly. No competition results in inferior products.
OR just get install an app on the phone that won't let you leave the calculator app in a certain time period.
The TI-83 Plus launched in 1999. The TI-83 was 1996. The TI-83 Plus has a 6MHz z80, and the TI-84 Plus CE Python has an ez80 that can reach frequencies of up to 48MHz These things are no more powerful than than an intel 80486 that launched in 1989. Going on 40 years behind the curve The TI-83 Plus is a little more powerful than a 4.77MHz intel 8088 released in 1979.
The TI 83 is expensive because a lot of crappy public schools require it.
Yes my friend, your old calculator has the same technology of my TI-86 and 84 from the mid 1990s. The processor is a z80 originally launched in 1976 (1 year before I was born). I will also mention that I wasn’t allowed to use a calculator until my senior year of high school which was 1995. It pains me to see other sectors of technology move forward while calculators stagnate. This makes apps like Matlab far more useful if you choose a math heavy study.
4:30 great idea!!!!!
anyone have 5.3.0 nspire OS?
Y’all haven’t bought a SwissMicros calc, or antique HP42
It's at least $200 here. Most of them.
And yes, my phone is a $140 Redmi Note 10 Pro with amazing performance, and can do everything these can but 1000x better. Only getting ripped off because of the test.
bro look like dewey from malcolm in the middle made a tech channel and i love that tbh
"Beginning with the 5.6 OS update in fall 2020, we have removed a system-level programming capability called ASM." By removing ASM you will not be able to play games I imagine so do you recommend upgrading?
just like you said, I bought it because it's acceptable in class and a phone is not. TI has (in times past) put forth a lot of effort to make it acceptable to use graphing calculators in class and to this point I am thankful (have you ever used a slide rule?); however, now they use that prestige to get big money for a low money product. like you, it was by way of force, the best choice that I was allowed to make.
No one will make a $100.00 phone without WIFI or cellular technology because there are no profit margins in it. Also, Texas Instruments has its own chip manufacturing plants and partnerships, allowing them to get chip pennies on the dollar. Also, since Texas Instruments has such a monopoly, no cellphone manufacturer would ever be able to get their device approved on exams by the school system since Texas Instruments hold so much soft power over them.
The other reason, as you mentioned, is that you can't use phones since every normal phone could be used to cheat. And no phone app or app developer has the resources to create software and teacher training programs that can be used in every school district across America.
It's also more than that. Texas Instruments literally works with schools and universities to help students learn the fundamentals of math education and has many resources that only they are only equipped to provide. No other company has been built from the ground up in such a way to provide such resources.
Also, why fix what isn't broken? The TI-Calculator has been the only calculator used in American schools since calculators replaced the slide rule.
And you don't need a powerful device to do mathematics. The only time you would need that is trying to run very complex computer algorithms and such. And PCs are already used for that. Plus we created the atomic bomb on a computer that weighed over 30 tons and was only 1-bit. But it was still far faster than humans and made an impossible task possible. And the TI-83 Plus is a lot more powerful than that computer.
And keep in mind that just because a device like the TI-83+ Plus is still made today doesn't mean it hasn't undergone small under-the-hood modifications over time. So the ribbon issue may no longer be an issue on newer generations of the device. The TI-83 Plus today is still often considered one of the best calculators around.
Then you are an idiot. He didn't literally mean make a calculator out of a $100 phone without the radio chip. He meant you can just use the processor and touchscreen of the $100 phone to use in the calculators without any significant increased costs (it would only be pennies more as those processors are literally less than $5-$10 a piece). He was basically trying to prove it can be done by giving an example ($100 phone without radio chip, etc). Casio (One well known company for graphing calculators) can easily take a processor from a 10 year old phone, create a touch screen for a combined increased cost of $10-$15 per calculator and literally become the monopoly over TI (give reviewers free calculators, and schools free calculators, etc). Nowadays programming is the thing (Python especially). The calculator will become dual purpose, a graphing calculator and a programming machine. If I were a millionaire, I would take cheap current processors, cheap ram, cheap touch screens, etc and partner with desmos ( or a solid staff of 25-30 people) and create a graphing calculator with physical buttons who software (ease of use) rivals TI. Then I would pay millions for advertising (videos showing speedtests against TI calculator,s displaying programming support, etc) and donating hundreds of calculators to reviewers and thousands to top schools with documentation. I guarantee not only I'll profit tremendously but I'll become the monopoly in 10 years or less.
There are a few Android MP3 players that the manufacturer could install, all without WiFi. I bought one, and have yet to figure how to load anything.
In the UK schools suggest Casio graphic calculators
not to mention they dont want u buying used calculators with their student software
how about this .... for the past 50 years no can put 5 % 60 = 3 and or to type in az 60 % 5 = 3 on any calculator it iz 0.05 and or %x when in fact there are only 5 main types % x ÷ + - and each can do the same thing .... one symbol to the equation but it dont exist any where
UA-cam channel lgr has a video explaining it pretty well, I live in Mexico and I actually preferred HP prime, tho I really hate I can't share documents and programs with classmates cuz I'm the only idiot who doesn't own a TI nspire, still mine is quite faster and easier to work on.
Nice video btw bro.
price is not higher because every school use TI calcs, it is high because TI pays a lot of money to schools teachers and all the related persons (very similar to how pharmacy company pays to doctors for prescribing their medicine) so that they will ONLY use TI calculators and also encourage students to use them. this is also similar to why textbooks are expensive, because publishing companies pay to schools, as bribe to adapt their textbook and students have no other choice, so basically the amount you paid on TI calculator is not all on cost of calculator itself but a most of it is spent on schools and teachers and may be govt persons.
Please show some evidence of these payments to teachers…
Thanks for answering my burning question. TI N-spire CAS application for laptops is quite shit also. It looks and feels like it's from the early 2000s.
Simple. Because nobody applied and paid for certification.
Graphing calculators just got basically "disallowed" here, as we will at some point switch to computer algebra systems (or back to standard scientific calculator), but Geogebra is not done with their certification yet.
A good video and wise thoughts.
Greetings from Germany.
The TI-83 *Plus* was released in 1999, not 1996.
TI has the calculator market cornered in the US and Canada, not necessarily in other countries.
See:
ua-cam.com/video/zoGl8-Wc-L0/v-deo.html
They dont make any new Graphics calculator, they stopped making them years ago
Like the review I use the HP prime the new one is faster however as you mentioned the phone is just good or better. The TI calculators are using old processors by today's standard and charging much more money for even the old outdated defunct graphing calculators like the TI83 which makes no sense what so ever or why are they even being sold.
The Z80 goes back to the 1980's microcomputers. The new Inspire uses an ARM CPU.
bro how, these calculators are weaker than a ESP32 and that costs like 5 GBP (consumer, even cheaper in mass production) and the SAME DAMN screen I HAVE AND ITS 11 GBP!!!
What the heck is going on here in the comments????
No matter what I post, it's being deleted after a few seconds.
I'm not doing that
HP probably has better support if you are using it in a business. I reckon HP likes microsoft, adobe, autodesk, wolfram, and ab initio better than TI
Casio is used over here and Asian countries. Only standard in the USA, Casio is bigger elsewhere
TI is dominant in Europe, as I understand it.
I wish the trackpad on the Nspire did not exist as it is the most annoying thing I've ever dealt with. That and they use the cheapest plastic known to man.
maybe have a script
they also have very little storage Why don't they just simply put in a micro SD card slot
the 83 came out in 99 not 96
Wait... you can still get TI 83 Plus calculators? My interest in TI started back in 93 when I saw it in Kmarts... if I've learned anything over the years its all about creating a monopoly with text book companies
Well, if worthless school textbooks cost so much, I guess it makes sense....
I wonder how much profit texas instruments makes selling their graphing calculators
About 2% of their corporate profits of around $6.5 billion, so probably around $130 million. I’m sure the profit margin is huge. This is for calculators in total, though, most of which are simpler scientific calculators which likely have even larger profit margins than the graphing models.
Never seen anyone with a TI, it’s basically always a CASIO
Maybe review the numworks calculator?
You can finally download actual graphing calculators for your phone Without having to do the work around but obviously a real calculator is nicer to use. It's just ridiculous how you can get one for free on your phone or a $100 is your only other option unless you buy used
I just never had a graphing calculator, cause I'm ✨p o o r ✨ 😎

thats so expensive. for those older generations, atleast here in europe, I find them for 1-5 euros in my thriftstores. like I just saw a 84 plus for 2.50 in very good condition last week and didnt even pick it up because I stuff like this often. I really didnt know they sold them as new there thats such mean way into getting people to spend on outdated tech.
Wow, didn't know how cheap they were over in Europe.
Good job trying to start up on UA-cam, your biggest problem I can suggest on fixing is looking directly at the camera. It’s distracting that you aren’t looking at the camera
I will try to solve that issue
You'll build confidence and personal style, quite naturally as you go along.
I misplaced the monitor for the camera, usually I place it really close to the camera. Thank you for the feedback.
All one needs to do is search
for a youtube video on the HP Prime.
very interesting vid !
consider adding a little editing tho, so that you can give more energy to you video
Thank you for the feedback, I will implement that in my next video.
You got right kid, monopoly! However, outside the U.S. Casio and HP are kings!
Your my hero I love you so much ❤ thank you so much for this amazing video titled “Why are graphing calculators so expensive?” Truly an inspiration to this generation. Although I have to critique your knowledge. The calculator was not from 96, it hit the shelves in 96 but was created in 89, it was lesser known and took a minute to become popular. Anyways just some more information, also it’s not 100$ it’s actually 102.23$ last time I checked. Those are my critiques. Anyways thanks. My 4 sons all watch your content and really enjoy it. We live in a 1 bathroom 1 bedroom house with a twin. So we stack up to the ceiling to have room. Anyways I’m just rambling on have a good afternoon.
Isn’t Casio (inventor of graphic calculators) cheaper or for CAS hp prime faster and cheaper than ti inspire. Why do you stick to Ti
Because in the US the teachers have knowledge on TI calculators and limited knowledge on other brands.
What? Me worry?
Good video, keep it up. Teachers aren't teaching math anymore, they are teaching calculator classes. This is a cruel reality in industry as well. The Schools are given heavy support from manufacturers to promote and pimp their products and in turn it creates a ready made market of addicts that are then hooked on the devices going forward to college. The "L" word is overused in casual conversation. Try to find an alternative. You're doing a good job here by asking questions and pushing back. Keep at it.
“They are teaching calculator classes” - that’s nonsense. You have to understand the math to even know how to enter it into a calculator.

Shhh...You're thinking too much.
Generally, you will see only engineers with an HP Prime. It is even more powerful than the TI-Nspire CX CASii. However, the problem with the HP Prime is you basically have to be an engineer to know how to use it.
I totally agree regarding TI. The 83/84 black & white calculators have already been around for about 25 years. They shouldn’t be selling for more than $50.
I got my first graphing calculator at the tender age of 57, just for kicks. HP Prime. I printed up the 600-page user manual and am getting to know it. I am an old science teacher-- definitely not an engineer. I'm glad I made this purchase.
@@patrickbyrnes118 It’s a great calculator. Also the most powerful one you can buy. The only problem is it’s a big learning curve.
Yeah, TI sucks. I pretty much limit my TI purchases to either TI-8x's for friends and/or family, TI-99/4As (got plenty of those), or TI calculators with Red LEDs (although I have '74s, 66s, & 95s as well). I also have a TI-Nspire CX II that I will be putting Linux on.
I just bought another HP G2 Prime brand new from Amazon for $129, so anyone who says that you can't get them, point them here. A Numworks for I think around $99, it pales by comparison to the Prime, but it makes a nice addition to my collection. There's the Zero calculator out there, but there is zero information on it.
But the Prime is simply awesome. TI ought to be ashamed.
BTW, I recently bought a couple of used calculators, a Sharp PC-1600K and a HP-41CX (just to name a few).
I scored a like new prime g2 for $60 yesterday. Fantastic calc. Thought my 50g was awesome but the prime is so quick!
@@diversionmary That's a heck of a deal! Congrats! And if you weren't aware, there is an old school forum over at hpmuseum.
The most advanced TI calculator still uses an old 8 bit CPU.
Ummm… no? The nspire series uses 32-bit ARM CPUs.
