Portable USB power supply for less than 5€

🔌 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!

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

[@dariocose]

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

[@zachh7375]

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 TH-cam. You've earned a subscriber from me ❤ keep it up

[@dariocose]

Thanks so much for your support and your kind words!

[@dhdani]

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]

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

[@dariocose]

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]

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]

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

[@semaja2]

@@dariocose you got this :) everyone’s a bit nervous at the start, but stick with it

[@edwardfletcher7790]

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

[@liforra]

You should really use your real voice, some people will be dicks but no matter what ur voice sounfs like its always better then ai

[@dariocose]
