Actually i would love to. Been looking over some circuits but truth is I lack expertise. I would be comfortable assembling a circuit if i knew and had components. So far i only dealt with bunch of Arduinos and RPi. But all breakout boards have already been assembled.Now, why don't you make one?
Now that I have a junk throw away power supply, i might try repairing it replacing what blew up. Would be great to upgrade anywhere i can.
At the end of the day, I still need 14v 40amp power supply.
