🔌 Today I make a cheap mini power supply.
All you need is 10 minutes of free time, a soldering iron and a 3D printer.
Have fun!

This is awesome! Can't wait for the version where you test the version with the ammeter👍 I mostly power esp32s which can draw upwards of 600mA (when using wifi) at 3.3V which is totally in reach of this project! I love content like this and wish there was more on UKposts. You've earned a subscriber from me ❤ keep it up

Thanks so much for your support and your kind words!

And many do not have a 3d printer, so there goes %75 audience.

You are right. The next one will be made of wood 🪵🪚🌈🦄🎉

Those trim potentiometers have a very limited lifespan, if you constantly adjust the voltage. I recommend replacing it to a proper one, that has more turn cycles.

@joakimjocka8022 27 днів тому

i also have this module, how many amps can it put ou?

@dariocose 27 днів тому

Depends on the voltage... You can use the formula Ampere = Watt/Volt

Was interested but the AI voice instantly made me uninterested :( try using your real voice

@zachh7375 26 днів тому

He probably a reason. The video was clear and incredibly easy to follow, which might not be the case if he used his real voice 🤷. This clearly isn't scam content, although I agree that even a strong accent is better than an AI voice...

@dariocose 25 днів тому

I am setting up to improve the voice-over in my videos... All I need is a good microphone and some courage 🙂

If you're really concerned about your accent. There are far better robot voices you could use....
