Congratulation, good job. Your electronic load is a big update. I like your desing idea really much. The Display is the biggest Update, the old disply was too old school but now everything is fine now. You are using a hall effect sensor to measure the current, thas a good idea but i think to measure the current directly from the shunt resistors with a percision op-amp would be a good option. Finally you made it again, great projekt. I hope we see more from your engineering skils of DIY. Big thumbs Up.
Thank you for your kind words. Yes, I could be a good option to use a op-amp if you dont have a current sensor, it's easy to implement that but the hard thing is to write the correct code in order to measure the current correctly and most important precisely, and then comes the question, why to complicate things?, because INA219 is not hall effect sensor, it is a high-side current and power monitor IC, basically it does the same thing, for current measurement it's using a precision op-amp to measure the voltage drop across the shunt resistor, on V1 I used ACS712 wich is a hall effect sensor, anyways by using INA219 with a few lines in the code we can easily display voltage, current and power with quite high precision, and by selecting the desired full-scale current range to 400mA we can measure down to 0.1mA and at 3.2A full-scale we can measure down to 0.7mA, I think is more than enough to have such a resolution for this tipe of project.
I'm a tattoo artist, I really like your power supply, it's great that it can be replaced with an up and down button with 2 separate channel voltage storage.
very very good circuit !!!! thanks a lot friend.....congratulation !! I will modify your circuit with an ina226 and with three bigger power to247 mosfets to get to have 10a as maximum current
The potentiometer that I used is linear, and to answer to your second question, unfortunately I do not have the time for that, I barely have time to work on my next project.
Amazing project, I like the TFT screen. It appears (error I could not create the program) when opening the sketch in Arduino IDE, could you help me? I think it is damaged, could you upload it again? Thank you very much.
I don't think that the sketch is damaged, is more likely that Arduino IDE itself to have a problem that causes that error, try to reinstall the program.

An amazing project. Thanks a lot for share your work
You're welcome! 🙂
Very neat realisation !
Thanks!

This is not a power supply, is a electronic load.
As always, great project!!!
I’m also making a USB tester now, only the firmware is much better, there is auto-detection of protocols, all sorts of triggers, memory cells, etc.
Share your project please
I love this project ❤❤❤
I'm glad you like it, and I hope is helpful as well !

thanks for sharing 🙏🙏🙏
You are very good and make beautiful project! THANKS FROM ROMANIA! 😊
Și eu îți mulțumesc! 🙂
Nice project
Thanks!
If I want to make a tool like that with high power, can I just add mosfets in parallel?
Thank you!
What transistors did you use for power dissipation ie. Q2 and Q4 in your schematic?
Dear sir how to make T210 soldering station?
I will probably make a video about it in the near future.
@@HMProjects i waiting for your next Videos
Hola, ¿el PR2 de 5k es lineal o logarítmico? Could you make one with more than 5 amps with the TFT screen? Thank you.
The potentiometer that I used is linear, and to answer to your second question, unfortunately I do not have the time for that, I barely have time to work on my next project.
How can i up this to like 300w ?

@@HMProjects I renamed the sketch .ino according to what chat gpt told me and it was fixed
wah❤
Please,share garber file
in next project..
can you make atx bassed arduino bench power supply
To many requests from you guys, to little time make all of them. 🙂
@@HMProjects take your time no hurry😊
you could made metal box 👍👍👍👍👍👍
Why?, I already had this project box.
Nice project
Thanks!
