- Schematic at 2:29
1º-Power the DC Step-Down module using a transformer from 4 to 30 volt, conect the amp meter to the source "in"
2º-The yellow wire is pluged to the "out" positive side of the buck converter
3º-The remaining bigger black wire is conected to the "out" negative side, the the red is the output negative

Muito bom , trabalho fascinante!
Thank you for ur idea. That's very helping me a lot.
Can I use this supply for mobile phones for testing? Reply plz
what an awesome craftmanship... really appreciated !!
Nice job . Thanks
can you send a link to your mini driller?
So cute! And you gave me some ingenious ideas. You've got yourself a new sub!
Im sow bad know english, but, man, you firestarter😉👍👍👍
Excelente video, puede enseñarnos a hacer un cargador de batería con una reguladora de voltaje y la conexión de la pantalla voltimetrica para cargar batería de moto
請問一下 小電鑽鑽孔的鑽頭叫什麼??
¿¿¿Donde la venden????
