I absolutely like the idea! Huge success!!
It is amazing to have people like you sharing their hard work for free as open source!
Thank you so much!
Aggreeeeee u …sometimes i find people like this.. they sell that what they have done.. but its up to the creator
@@ELECTRONOOBS Sir if you want to see "good inovation" and truly "cheap/free" energy, you have to check out the "hydraulic accumulator" that they published couple of weeks ago. It changes completly the rules of the game forever! ua-cam.com/video/uTbIJnEOw8Y/v-deo.html
There are no someone's ideas, our brains take informations from the environment and put them together by natural laws depending on needs, basically everything is open-source, patents are closing off human knowledge and stop progress this way, patents are anti-natural anti-evolutionary, that's why almost nobody can understand the things they use all the time, every generation starts from zero, except for those who work for the companies that own the patents. Not everyone has the same abilities and this is why we need each other, he still can profit from it, in first place in the natural way with his self-esteem by knowing he does something that other people like or even that is important to them and in capitalist way by using adds for his videos and selling things from single parts up to complete devices.
I think you've done an amazing job with this design. I tried the same a few years ago and ran into too many "small technical issues" that made mine inaccurate and I gave up. Well done, I'm going to build myself one of these. Thank you for the countless hard hours of work.
For the next pcb, I would suggest adding a USB C connector. It would require some more space and 2 5.1k resistors on the CC pins (I think), but it's much better than USB micro. Also, adding pads on the back for a usb to serial conversion chip, would make it so much easier to program because you could just plug it in to USB.
Actually micro b is better although it's more fragile but it's much thinner and will fit in it
With the cluster* of USB-C standards, I actually now prefer micro USB for anything that has low power requirements (up to about 3A)
@@JB-fh1bb what cluster of USB standards? USB-PD isn't a moving target.
@@entx8491 No? Did you know that a USB-C charger manufacturer can choose which voltages it supports? Out of a dozen chargers I don’t think any two supply the exact same list of voltages. 5V, 9V, 12V, 15V, 20V, “3.3-11” (whatever that means). These are all USB-C PD. I even have a bunch that supply 5V, 9V, and 15V, but NOT 12.
Yes please
The atmel 428 gets used heavily in component testers. Perhaps add that functionality too so it can identify most major 2 and 3 legged semiconductors? Accuracy still has some problems, but this project has tons of potential. Last week I was looking at pen style DMM's and refrained from getting one. I think you gave me a new project! Build one of yours!
Man I really appreciate it making it free
I bought one similar to it months back somebody else must’ve come up with the same idea where it’s yours it was earlier version the only thing difference between when I have the one you’re having now as it doesn’t have a screen on it but it’s a very useful tool I haven’t used it too much because I haven’t done too much but it’s getting there thank you very much your video was very informing
You are a legend, man!
I’ve been doing battle with two cheap LCR meters that I can’t trust to give me accurate readings, and my very accurate Fluke meter doesn’t measure inductance and can’t measure capacitance under 10nF.
Thank you very much for uploading this video!
Well done, when I was your age, I suppose in your early 20's, that's nearly 40 years ago, I made a voltmeter with 3 x 7 segment LED display that could fit inside a 9V battery case: I used the old CA3161 and CA3162 full size DIL Chips.
That was only a single range volts reading, you made a full multimeter.
Personally speaking, I absolutely love this project.
Well done mate.
Your timing is perfect. I've literally been shoppibg for some kind of a super handy meter for testing things things that are mounted to a wall, for example. Trying to hold the meter and the probes sucks a LOT.
Awesome job!
Just my two cents... maybe a good idea is to use a replaceble pogo pin (the ones used for ICT) which are fine pitch and retractile with some resistance to avoid damages.
The integration with the glasses though 🥵🥵
U are the king of micro controler…youtube should give u crown.
Please make V2 of the digital electronic load, with all safety functions....
Meu amigo você é incrível, seus canais só tem projetos e dicas TOP (é assim que falamos aqui no Brasil quando algo é muito bom e de nível elevado), mas com esse projeto você se superou, esse é top, muito top mesmo.
Mi amigo, eres increíble, tus canales solo tienen proyectos y consejos TOP (así hablamos aquí en Brasil cuando algo es muy bueno y de alto nivel), pero con este proyecto te superaste, esto es top, realmente top.
My friend you are amazing, your channels only have TOP projects and tips (that's how we talk here in Brazil when something is very good and high level), but with this project you surpassed yourself, this is top, really top.
Try to add a component tester, frequency generator and basic oscilloscope to it, I think about it for such a long time already but don't make it to realize it, would be cool if someone could finally do it. Very cool man, it's not the first time I see you creating something I plan but don't make it to realize for various reasons.
This is like the best project,awesome work!
Im 15 years old and your videos are very inspiring for me!
This thing is awesome! Maybe consider sending this over to Dave at EEV blog youtube channel when you finish it up. He even has a mailbag to send him stuff
Great job my friend ✅✅✅✅✅✅✅✅
Me encanta sobre todo la posible conexión con las gafas para ver el voltaje, sobre todo para saber en placas de componentes smd si estás midiendo correctamente o no. Me gusta mucho este proyecto 🤠.
I’m SO ready for a “TS-100” of multimeters!
Awesome project, glad to see the continued progress and evolution of the multimeter idea. The compact form factor is excellent and very practical indeed. Keep up the great work
This is awesome. I've been looking for something just like this. Thanks for putting this together.
Hi very interesting project, maybe I suggest you can use MUX and analog switch SMD for encode the functions and only use single switch for select the menu of your multimeter
Nice little multimeter! Something I'd actually like to have in a small tool bag for when out in the field with my radio gear. Especially for checking inductance.
Using an ATMega leaves you with a small voltage range that will never be as accurate as dedicated chips for measuring voltage, but it does let you have all the other features. its a trade off
Great tool , I cant wait to see the measurements on the glass.
it seems to be a revision is needed .
Some improvements I think would be nice to add are,
Tp4056 li ion charging block,
mAh count function for rechargeable
Watt measurement function
Autorange for voltage and ohm measurements
Oscilloscope function
Wave generator function
All the functions mentioned here can be gather on two parallell boards.
you might think to continue with a kickstarter project after some revisions.
you could get rid of the two slide switch and just use an extra button for a menu system on the display. like the ts100 and ts80. it will make the case more thin and better to hold
It's an awesome project! Is it a 16bit ADC converter like in the previous model?
The only thing missing for me is a small buzzer for continuity test
Every electonix hobbyist dream tool!-😱😘
holy moly, thats amazing, have no words for this
Another great project Andrei! I look forward to seeing the next version of this project. Thanks for all your hard work and sharing.
Amazing work! You can add a reverse measure button (switch the 2 probes => diode/voltage polarity).
Wow, what an amazing little gadget, congratulations on coming up with such a fantastic and complete design!
Did you ever get around to making the additional enhancements you mentioned?
I’d gladly pay some nominal amount for the improved design to support your work, have you thought about maybe selling the design files for the improved version? (Or maybe it’s already available as a Patreon bonus? I’m going to go check out your Patreon now :-)
Nice! You should sell this as a kit!
You are using on one side some very big component for example the tp4056 ic for charging the battery. In my case I use for such small battery's the TI mcp73831 ic, a smaller alternative to the tp4056 ic. 500mA max charging current instead of 1Ampere.
Using a rotary encoder is the best choice for this little project. I will defenitively recreate this project when the final version appears, I am looking for a pen style multimeter all the time. Thumbs up
Omg man, you are amazing, this project is great !! And complicated as well. Good job !! Really apriciate that is open source ! Good luck in what you're doing !!
Would be nice to have the indicator in a formated view, the number right aligned.
wanted features: instant beeping for continuity mode (or tiny vibration motor instead of beeper), and non contact AC detection (maybe on the back/rear end of the pcb
Thank you for your video, it's an awesome project and I think you are very cleaver designing and making it.
I would love to have one but at my old age I don't think I could solder all the small components, but thanks for the videos
Very interesting project,Thanks for sharing your knowledge, Thanks.
If you run into trouble, developing an Android application for BT connection, feel free to reach out. I really like the project and already used some of the code on your website. Since you obviously want to have barely any inputs on the device itself, you may want the pwm function generator to be a BT controlled feature.
Very nice as always ❤️
Shipping on PCBs from both JLCPCB and PCBWAY makes the price way higher than in the video, at least to Canada. A $5 PCB with $25 US in shipping is just insane. I really wish shipping costs would come back down so projects like these were more reasonable. :(
I realize $30 might not break the bank, but I just have a hard time justifying spending 5x the cost in shipping.
dang, what a cool project! thanks for sharing it
Super nice! Thanks a lot! You can even call it IoT multimeter.
It's kinda cool project. Liked it 👌
fantastic job. Nice work. congratulation to you. Thank You
Great project. Definitely on my TODO list
This is great project with lots of hard problems to overcome. Great to watch. Why don't you have the boards populated in China? It's so inexpensive to have them do all the part sourcing and soldering.
The problem is that is double sided and to solder parts on both parts automatically is very very expensive....
Very cool project!
Watching her in Philippines.
Thats a pretty handy device
Great project!
Nice concept and realisation. Looking forward to the completed project.
Gran proyecto, cuando en español 🧐
Very cool and nice project
Very good work and idea. Like so much!. Thanks.
Amazing work.
Nice work man
Great project
Pls make rf spectrum analyser if you can
You can change 2 switches by HC4053 Multiplexer/DemultiplexerHigh-Performance Silicon-Gate CMOSThe SL74HC4053
Very nice project
There's is bt module so there's also Its App for data recording and UI features ?
Hi there this looks great I think that I will probably have a look at building one and maybe the glasses
Could you use the comparator that is used for the frequency measurement to drive an analog switch to do the rectifier for AC?
You could also bias up to mid span on the ADC for the AC measurement.
Really awesome !
Great video thank you for sharing
Amazing project, will be awesome if you implement some kind of temp measuring with a thermocouple probe. I will be waiting for new updates from the project. Really good video congratulations 💪🤟
nothing of noobs here...lol maybe 6 years ago
nice project my boards are on the way
what about osciloscope incorporated via bluetooth to screen? and transistor tester at least lol
it would be a great adiition as pokit-pro
keep updating firmwares plz
All the best!
Nice project..
Awesome, no word to appreciate
Amazing 🤩 btw waiting for the laser projector project 😊😊
Good Work Brother👍🏻. That's why I never miss a single video from you💓.
Keep it up 😇
This is awesome and I would be happy to put my name down for one or a kit of one or something when it's finished.
Someone has already done this, see the Pockitmeter Pro. It is way more advanced than yours, bc they've been working on it for years, had better manufacturing capabilities, etc. They also started with a better uC. The final product is an actual final product, worthy of being mass-marketed. Their PC & Android software is a little "clunky" but they were trying to get the hardware right, now they can finish developing the software!
I know, it's nice to build things yourself. But in my case, I've gotten that out of my system, and have projects to work on, so I need a functioning multimeter. So I'll go with the pro product that's already finished, & I don't have to assemble it!
Cheers!
In general, I'm with you but I think it's unpractical to always have to use a smartphone for a meassurement. For me, that's a no go.
I really like it 🙂
If you had used a better microcontroller (like a 16-bit, with more timers, more ADC bits, etc), you'd have the basic building blocks for more features, plus greater accuracy with the basic DVM functions.
Otherwise, nice work!
(That's why I don't understand why you didn't start with a better uP.)
Really cool. I wonder how much hours you put in on this.
Thank you for your awesome job, and for making it accesable, I really like all your videos
Very nice!
Perfect project,i cant find that big board version in your videos,i think it’s easier for me to made at home.i don’t know which of your video is last version with big board?
This is going to be awesome 👍
Nice work brother.
Will be waiting for the next video
Awesome project and beautiful work as always. Can't wait for the upgrade. Can you please tell me what software do you use for the 3d box that you made...do you use another software for 3d animation or the software that you use has this feature?
9:20 you did it in little wrong way..
Because if you add options to switch two probs at The front So it can easily measure smd Just like smd twiser and other wise also as separate Probs .
I love your projects. But I am curious why do you never use ESP8266 or ESP32 instead of arduino. Those are cheap yet more capable.
Also in next version could you add thermocouple based temperature measuring system?
For very simple projects like this, arduino is more than enough. Also the power consumption of esp is much higher than atmegas
Please add continuity check with a little buzzer.
awsome bluetooth, so community can make android os for the display
great job
You should make the product and sell it sir its very good
Love it!
Awesome project 💯
very interesting watching you work through this especially some of the problems which crop up with these types of projects I think this would make a great product and if you or somebody else could manufacture it I think there's a big market.
You could probably mass produce them with JLCPCB if you ordered the components from LCSC. If you try and put as many components one one side then you can use the SMDA service and hardly have to do anything, just solder any components on the other side
Wow. So cool.
Perfect! i want one☺️
Great! 👏👏👏
are you really Spanish ??
holy moly guacamole, that's the first time I hear it from you
