/diy/ - Do It Yourself

>>1430545
Eh, fuck it, if i need to get a PhD in fucking battery charging to make the regulator, I will just throw money at it and buy this cunt instead.
That way I can use the extra LM317 to rig up an USB plug and charge my phone with it by connecting it to that load output on the solar regulator.
It's still lots of volts to step down from 12V to USB 5V but since the phone only draws 1A, i should be able to handle the heat by attaching an old cpu heatsink to the LM317.
Altough later i will buy a proper buck converter from Ping Pong so i don't have to waste all that energy as heat.
Hm... i should properly try it on an old phone first just to be sure though.
