Homemade variable power supply, ideal for testing leds, motors and other electronics:
Dual Meter : bit.ly/2u6Uykx
or bit.ly/2T8ItVK
DC module : goo.gl/J9oZwy
4mm jack : goo.gl/93L5mm
Power jack : bit.ly/2BMSMsw
10k precision potentiometer :goo.gl/oq6SrG
or goo.gl/SyZ4Qo
or
Normal 10k Potentiometer : goo.gl/uqZDMe
Multi charger: goo.gl/RzrCf8
or bit.ly/2GIQ09Z
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
