PC B Im 14 year old , I bought new 900w lab power supply , made solar shead , renovated old house , bought new quad and cross , just go work on summer and forget everything else
I love that you show how cheap it can be to start up in electronics but also show why some of the equipment can be so expensive! Im in second year of electronic and computer engineering all because of your videos! I love them and i have done so many of your projects, most recently converting a laptop screen to a monitor (i made mine portable) Keep making amazing videos man!
You made a simple statement that made the "old lightbulb" go off in my head. (I''m too old for the LED to go off in my head...) You put in the resistors first! I would not have thought to do this, but putting the resistors first could help with minor static discharges! Brilliant! If I get nothing else out of your channel, THAT was worth the price of admission... Glad I subscribed!
This is exactly what the beginner needs, unbiased compassions that show what the cheap stuff can do. If you go to other electronic sites they talk down to you for buying cheap stuff, and want you to spend $5K to set up a lab for something that you might not continue, or will always only just be a hobby. I bought that cheap $25 DSO kit, and I'm surprised how handy it is. I would now like something better, but paying $500 for something I might only use 10 times is a waste of money as the $25 DSO - only used 8 times in a year - does the simple auto stuff that I'm only ever going to do.
That was an excellent comparison video! For $7 the functions and performance is relatively good and if one doesn't have better function generator, this kind of cheap "toy" can be very useful... It just may need some modifications and there are limitations. Happy New Year!
The function cheap generator I would recommend is the FY32024S. (Price is around 80 usd) As it has 24 MHz output for a decent sine wave. 4-6 MHz for Arbitrary wave forms, square, saw, and audio. Other then this it has rather nice build quality, the case feels really cheap though, not to mention weighs so little that putting in a lead weight could be considered and upgrade.
YES! i cant decide if i want to build a PSU or buy an Ebay one like this one. www.ebay.com/itm/30V-5A-Variable-Adjustable-Precision-Digital-DC-Power-Supply-Dual-LED-Dispaly-/222181019956?hash=item33bb055134:g:2wIAAOSwzJ5XgGNw
I have one of those 30v/3a bench supplies. It's OK to start with, but eventually I got exasperated with it and bought a Korad KA-3005D. The problem with the cheaper supply is that if you're trying to do something like test LEDs or something else where you need to set current limiting very low, like 10ma, it's very fiddly to get the setting right on the analog one. With the Korad I can set up several exact programs and flip between them instantly. It is 2 to 3 times the money. I'd say get the cheap one to start with, then go to something better if you find yourself needing it later. After all, having two bench power supplies is sometimes needed anyway. Korad makes one for a bit more ($200) that has two adjustable outputs, which seems like a good deal, but I didn't like how they set up the controls on it and decided I'd rather buy two 3005Ds than one of the dual output ones, when I got to where I needed another supply.
You can improve the precision of current knob by changing it to multi-turn potantiometer. You should keep in mind that the multi-turn pot knob is bigger than one turn one.
If you already have the parts laying around to build your own, that would be the cheaper route. Though if you do not have the parts and are going to purchase the eBay one doesn't look so bad.
Great vid from Great Scott, but I would like to suggest one more option - its AVR DDS. I learned so much from doing and modding it (diy pcb, avr programming, power supply, even micro-controller button debounce problem solutions, offset and amplitude controll, opamps rise times, clipping, lines rinnging etc). 16mhz avr may run any function up to ~60khz, and square up to 8mhz (well, it drops in big steps at high freq). Additionally, I combined avr with ebay AD9850 module, what brings ~40mhz sine. In parts it may cost 30-50EUR and 10000EUR worth fun.
If all you need is a test signal for audio equipment, give both of these a pass and build a Wien Bridge Oscillator. The NTC thermistor (one of several once-common panel lamps) can be a little hard to source, and you'll have to put a few standard-value resistors in series to get the right values from the application note, but other than that, it is fairly easy to build and produces a very low distortion sine wave.
If a channel such as this doesn't generate some desire in the mind of young people to attend some electronic courses at the university, I don't know what will !
Thank you for the video ! 1. Could you do a tutorial on how to use osciloscope and/or function generators ? How to use them in real example ? 2. Please make a tutorial on how to build yourself a robot like Cozmo, please. 3. I have a Lumia 1520 camera (20MP). Please show how to make a home build hidden spy DIY camera from it ? There are such thing on amazon but cheap made with bad quality cameras and bad quality overall. Also needed this tutorial just for fun and learning purpose. Thank you very much ! Happy New Year !
I have had one of those little kits now for a couple of years, it does the job for me when I need such a thing. That said, it is rare that I am in a situation where I actually do need it. The last time I used it, if I remember right was when I built one of those cheap oscilloscope kits, just to test the scope! Guess it worked for that. I have a signal monitor deal that I can hook up to it if I need to set a specific output frequency, that was a couple of bucks more on Ebay.
audio amplifier output always has a capacitor in series, hence they are not DC coupled. This is because, any 0Hz DC will cause continuous current in headphones/ speakers and it will burn out the coil.
for me this was just a fun soldering kit, at 5 euros it's really cheap and an additional usecase is using it to test guitar amplifiers. You don't need accurate waves there, you just need a wave.
Beside the problem of the DC offset at the cheap one there is the a PCB mistake for the left potentiometer (turning right means decreasing output instead of increasing). But you can fix this problem by changing two pin of the pot.
For the same price you can get the FF3224s which includes the capability of programming the generator with you're own wave forms as well as having a higher bandwidth. The one Scott linked is made in Germany, I wonder if this was a sponsored video? Anyways, it was still great! Have a GREAAAAT New Year!
They could have probably added an op amp buffer or push-pull output to the $7 one and vastly improved the output impedance without drastically altering the cost.
Hey Scott! Wanted to ask you a question. I have the same cheap function generator, thought mine was faulty because of the 'jiggles' i see in waveforms, but it made me somewhat happy to see you experience the same as well at 4:42. Any chance you know what is causing this? And how to prevent? By jiggle i mean the waveform shakes back and forth, creating ghost duplicates with different phase. Great videos btw, already subscribed. Keep up the good work, we need engineers like you!
I bought one of those exact models of kits and for whatever reason the output was incredibly small and the amplitude didn’t change when adjusted. I got a more expensive kit that was also very quiet so I ended up just making my own amplifier for it.
FWIW, these days you can get a full 2 channel 24 MHz arbitrary waveform generator with USB interface that supports frequency sweeping and all that jazz in a nice case for about $70 on eBay. The same units are on Amazon and the reviews there are pretty good.
For $7 that is an absolute beauty. Add a transistor buffer circuit and a bunch of parallel capacitors to make sure you pass all the frequencies correctly and you have a very usable basic piece of kit. Any good frequency counter kit that you would recommend? I have all the parts to build a 1GHz counter including the prescaler IC but i'm still trying to find an excuse not to haha.
You could also, if you already are buying a decent oscilloscope, choose a model where the function gen. are integrated. I have been very satisfied with the integrated function gen. in Keysight scopes. But nice video
Yes, a video on the oscilliscope kit would be awesome. You got my hopes up there brother, for a second I foolishly thought I could avoid paying 100+ for a functional generator. But as you say "You get what you pay for". You pay peanuts you get monkeys, right? And so on. Many thanks GreatScott for another upload.
you should do like a challenge where you have a project but you can only use cheap stuff, like a cheap soldering iron, cheap lab bench power supply, the cheap ociloscope and the cheap function generator
Hi there greatscott!, i have bought myself a DIY tube headphone amp kit, and have assembled it myself, the only thing is, its making strange sounds when playing music, almost like its fading in and out really quickly, I thought it might be the 12vAC power supply being rubbish, but im just not sure, the kit i have is similar to "6J1 Tube Pre Amp Amplifier Board Valve Buffer PreAmp Amplifiers DIY Kits Tube Preamplifier Board Gall Buffers Amplifier DIY KIT" on aliexpress
i might pick one of these up at a later time once i start getting more into circuit building. just got my first oscilloscope (the $20 one) and right now i'm just using and android app on my phone. seems to be good for less than 5k for square and up to 20k for sine. once i need the higher frequencies, ill will look into a proper function generator.
To have a known frequency if you need to track its way through a circuit and see if something changes, or to find what exact frequency you need for a resonant circuit. That would be my guess.
if you have a part that has been filled by the manufacturer with resin to prevent identifying it, you can put a known signal through it and measure the changes to figure out what the circuit is
great scott can you do a video on induction heating and how it works , also can you make a comparison on cheap chinese induction heaters and a homemade one. thanks.
Hi Scott, great video, looking forward to see what projects are coming in the new year! I have a mechanical engineering background but have been trying to get more and more into electrical engineering work in my spare time (through hobbies and otherwise). Do you have any recommended paths (courses, projects, or otherwise) for someone who might want to get more familiar with electrical engineering technology? (What are filters, for example, or how does an AMP work, how to construct an AMP, etc etc.) Thanks!
I don't know the etymology. It just is the convention, can't explain. Like why is the normal English sentence word order subject, verb, predicate? (not if you're Yoda of course, he uses inverted word order all the time). Why does English put adjectives before nouns, whereas at least in Spanish the nouns come first?
I ordered the DS1074Z Ocilloscope from Rigol, but they shipped me the DS1074Z-S instead (the same oscilloscope but with a 2 channel 25MHz function generator built in). They ended up letting me keep it lol.
wait... those nuts are stand ups and not to attach the pcb to the bottom plate? *goes away running to disassemble his function generator* good video! What about doing a video on those lcr-t4 component testers then? i got one for 7 euros + 4 for the acrylic case. Quite satysfied with it.
Hey! Can we add a non inverting amplifier using opamp for amplitude adjustment and for lesser output impedance? If yes then why isnt it a thing? Why dont they do it in the kit. Why dont people talk about this?
Hi there, nice video. I would like to know if you have considered to look for the cheapest function generator that provides you the "same"features than the expensive one? Thanks and happy new year
This video answers to my concern, I like it. But, what's about using Arduino/Raspberry/... as functions generators? I'm sure Scott may provide us with a simple circuit to do decent job.
I love the way you talk. When I read tech books I use your voice in my head.
That's creepy
Same. My Diff Eqns professor had a thick eastern european accent. Whenever I have to read dry math books/papers, that's how I imagine it
I read my c++ tutorials with a Jamaican accent. “FIRST....webegonnalearnaboutdastringMON”
you are in love?
Sometimes i listen to audio books when im working, then when i read an actual book, its in the robot voice in my head
He is the reason i will do electrical engineering 😀
Awesome!
PC B electronics and programming and mechanics = robots!!
Aneesh!! I already started electronics engineering and he helped me a lot with his great videos 😊
PC B Im 14 year old , I bought new 900w lab power supply , made solar shead , renovated old house , bought new quad and cross , just go work on summer and forget everything else
im already studying electro-technical school

Thanks to you I am now a student of electrical engineering! Thank you for the inspiration!!!!!
Cheers from Greece.
I really find your comparisons and reviews of cheaper equipment as it is helpful for us on a budget
Great review...you simultaneously made the statement "you get what you pay for" meaningful and created an informed consumer.
Love your projects man! I am an Electrical Engineering student, and I want every one of your videos....I learn more from them than I do my lectures.

How about comparing a low cost lab power supply to a high cost one? :D
YES! i cant decide if i want to build a PSU or buy an Ebay one like this one.

MrSandoron i bought a very cheap 20v-2a psu for 40€ and it works perfectly fine.
I have one of those 30v/3a bench supplies. It's OK to start with, but eventually I got exasperated with it and bought a Korad KA-3005D.

I like when you do value tools, because I have a very small budget for stuff. I actually bought the DSO138 kit you reviewed. thanks!
Your English intonation is improving Scott. Thanks for the content.
If all you need is a test signal for audio equipment, give both of these a pass and build a Wien Bridge Oscillator.

If a channel such as this doesn't generate some desire in the mind of young people to attend some electronic courses at the university, I don't know what will !
You could try to add that capacitor and feed it into an op amp setup as a voltage follower with a bjt or mosfet output stage
Love the title, how it's mocking buzzfeeds comparisons.
Cool video, didn't know you could get them as cheap as $7 :o
Great! I love your projects!!! Happy new year.
Thanks. Happy new year as well!
GreatScott! Hi alles gute Guten Rutsch unf frohes neues Jahr 2017.

Thank you for the video !
1. Could you do a tutorial on how to use osciloscope and/or function generators ? How to use them in real example ?

if you dont need high frequencies, you can use an audio DAC. I found that the headphone of my phone is DC coupled!
audio amplifier output always has a capacitor in series, hence they are not DC coupled. This is because, any 0Hz DC will cause continuous current in headphones/ speakers and it will burn out the coil.
Happy New Year, Love Your Videos, Great Scott!
I don't understand most of your video, but I like it, great video
I can't believe this guy doesn't have 1,000,000 subscribers (best quality videos!)
905k right now!
1.89M now
You are doing this buzzfeed titles now :D
I bought 10$ signal generator from ebay with lcd screen , I tested it on HAMEG HM203-6 and it works great
for me this was just a fun soldering kit, at 5 euros it's really cheap and an additional usecase is using it to test guitar amplifiers. You don't need accurate waves there, you just need a wave.
Great Scott is a meticulous Scott too, look forward to your great videos in 2017 too. All the very best 🙏
very nice video again..!!! Btw the cost of your CRO is more than the total fees of my whole electrical engineering. :D
Beside the problem of the DC offset at the cheap one there is the a PCB mistake for the left potentiometer (turning right means decreasing output instead of increasing). But you can fix this problem by changing two pin of the pot.

There is like 12$ kits with lcd screen and more features on ebay.
I will be sure to bookmark your channel as I will be doing electrical engineering fairly soon...

I am in love with your oscilloscope 😄
Me too, if I have the money😅
You are best in electronics. (Happy new year)
I bought this kit just to get started with DIY synths and minor repairs. :)
If you buy the separate parts on eBay you spend much more than 6 euro! Fantastic!
Could you do a video on that oscilloscope kit?
Buy a cheap DSO112A (or similar) instead.
ua-cam.com/video/x19kwG-wJRI/v-deo.html
I bought one of those exact models of kits and for whatever reason the output was incredibly small and the amplitude didn’t change when adjusted. I got a more expensive kit that was also very quiet so I ended up just making my own amplifier for it.
Got the same one for R170.00 ZA. Was wondering about the the DC offset... Got a GW 20Mhz crt scope for free!!! Thanks for your work.
happy new year greatscott.
Got so say, I own one of these and it is great for what I do!
He is the reason i open youtube
wow happy new year. .. my best wishes to you from India ,😁😀😃
Happy new year budy. Nice video
Happy new year for everybody❤️
Good unbiased, objective and helpful video. Thank You.
FWIW, these days you can get a full 2 channel 24 MHz arbitrary waveform generator with USB interface that supports frequency sweeping and all that jazz in a nice case for about $70 on eBay. The same units are on Amazon and the reviews there are pretty good.
You can get a lot more out of that xr2206 if you have a look at the data sheet
Happy new year! Great video as always Scott
HA bad pun is bad

Any good frequency counter kit that you would recommend? I have all the parts to build a 1GHz counter including the prescaler IC but i'm still trying to find an excuse not to haha.
I bought this little thing as my 1st function gen and it lasted 2 months now getting new one for $70
I love your awesome geeky detail! Great video as always!
Happy new year.
Happy New Year 'GreatScott' . :)
I enjoy your videos, and yeah, only have a basic knowledge of electronics.!!! lol
You could also, if you already are buying a decent oscilloscope, choose a model where the function gen. are integrated. I have been very satisfied with the integrated function gen. in Keysight scopes.
But nice video
Happy new year!!
Can you please make a video on rotary encoders?
Happy new year!
Yes, a video on the oscilliscope kit would be awesome. You got my hopes up there brother, for a second I foolishly thought I could avoid paying 100+ for a functional generator. But as you say "You get what you pay for". You pay peanuts you get monkeys, right? And so on. Many thanks GreatScott for another upload.
He's the reason I'm alive
Works great for audio circuits.... with some minor mods
I was looking for this in ebay n not very sure of its function. Thanks for your review.
you should do like a challenge where you have a project but you can only use cheap stuff, like a cheap soldering iron, cheap lab bench power supply, the cheap ociloscope and the cheap function generator
hey great Scott it would be cool if you did a comparison between all forms of ardino boards (mega, uno mini etc)
Hi there greatscott!, i have bought myself a DIY tube headphone amp kit, and have assembled it myself, the only thing is, its making strange sounds when playing music, almost like its fading in and out really quickly, I thought it might be the 12vAC power supply being rubbish, but im just not sure, the kit i have is similar to "6J1 Tube Pre Amp Amplifier Board Valve Buffer PreAmp Amplifiers DIY Kits Tube Preamplifier Board Gall Buffers Amplifier DIY KIT" on aliexpress
hi great Scott, can you make a video on things you can make with the N555. btw what do u do in your free time,happy new year
I already did a basics video about the 555 timer
GreatScott! I meant what u can make with it
+GreatScott! make some projects using Ne555
Yes! Make some projects using 555 timer!
happy new year to you sir
like your videos! Respect from RUssia!
your function generator is the first instance of Æ in a model number I have ever seen
i might pick one of these up at a later time once i start getting more into circuit building. just got my first oscilloscope (the $20 one) and right now i'm just using and android app on my phone. seems to be good for less than 5k for square and up to 20k for sine. once i need the higher frequencies, ill will look into a proper function generator.
Happy New year- You should do a ESR video
Matt Zelonka yes a ESR comparison would be helpful
What is the reason for using this machine?
To have a known frequency if you need to track its way through a circuit and see if something changes, or to find what exact frequency you need for a resonant circuit.
That would be my guess.
A Real Stoner Story it gets the girls every time!
if you have a part that has been filled by the manufacturer with resin to prevent identifying it, you can put a known signal through it and measure the changes to figure out what the circuit is
Aeolwn how
Aeolwn Thanks for your efforts.
Great video. Very informative nice job! :-) happy New Year dude!
i think the crazy advanced functions come from the software
That's good to know that it has the DC offset at the output..
You can use an voltage follower
have you ever done things with digital circuits or logic gates such as FPGA boards? maybe an idea for a future video.
great scott can you do a video on induction heating and how it works , also can you make a comparison on cheap chinese induction heaters and a homemade one. thanks.
Hi Scott, great video, looking forward to see what projects are coming in the new year!
I have a mechanical engineering background but have been trying to get more and more into electrical engineering work in my spare time (through hobbies and otherwise).
Do you have any recommended paths (courses, projects, or otherwise) for someone who might want to get more familiar with electrical engineering technology? (What are filters, for example, or how does an AMP work, how to construct an AMP, etc etc.)
Thanks!
BTW...we SAY "seven dollar," but when writing it with symbols (e.g., €, $, etc.), the symbol (generally) goes first, such as "$7."
But why?
I don't know the etymology. It just is the convention, can't explain. Like why is the normal English sentence word order subject, verb, predicate? (not if you're Yoda of course, he uses inverted word order all the time). Why does English put adjectives before nouns, whereas at least in Spanish the nouns come first?
I ordered the DS1074Z Ocilloscope from Rigol, but they shipped me the DS1074Z-S instead (the same oscilloscope but with a 2 channel 25MHz function generator built in). They ended up letting me keep it lol.
not to mention the slower rise time with the square wave.(on the cheapie)
could you do a teardown of your Function generator?
wait... those nuts are stand ups and not to attach the pcb to the bottom plate?
*goes away running to disassemble his function generator*
good video! What about doing a video on those lcr-t4 component testers then? i got one for 7 euros + 4 for the acrylic case. Quite satysfied with it.
Hey! Can we add a non inverting amplifier using opamp for amplitude adjustment and for lesser output impedance? If yes then why isnt it a thing? Why dont they do it in the kit. Why dont people talk about this?
Is your time better spent diagnosing your tools or your projects?
where is the cheap oscilloscope from you showed in the video?
I presented it in a previous VS video
happy new year
Hi there, nice video.
I would like to know if you have considered to look for the cheapest function generator that provides you the "same"features than the expensive one?
Thanks and happy new year
This video answers to my concern, I like it. But, what's about using Arduino/Raspberry/... as functions generators?
I'm sure Scott may provide us with a simple circuit to do decent job.
Scott..love your work. Scott can you please send me your oscilloscope spec. and how and from where to buy if it's cheap..😜😂
awesome video credits: great scott!
Make a video about diy oscilloscope from true hole components.
Through hole*.
Yes
nice video happy new year
