I WANT TO LEARN THAT...build a circuit..learn what you are doing but i dont know what course should i take in college..! its electrical engineer or electronics engineer?????....suggest me pls..!
Except in my case, I need a 130VDC source to trigger a coin relay in a Western Electric 1D2 pay phone. Yes, I know I can modify it t use a lower voltage but I want to keep it original.
Line voltage here is 125VAC (I've measured it!). So a 1:1 isolation transformer into a bridge rectifier and sufficient filtering caps should give me what I need.
Good video, Collin. I can see you wear at least a 7 5/8 hat (XL) like me.
