Achievement unlocked: Unisolder revived

Clicking is the current limit of my PSU

2018-05-21 22:13:42 +0000 UTCExcellent work. You were the inspiration a while ago that caused me to attempt this build. It's infuriating and gratifying at the same time. I had the power board working and when I went to plug in the digital board or blew up the 74hc02 for some reason. I built a second power board and when I tried powering it from my small bench supply it seemed to kill the large transistor next to the voltage ic. The third power boatboard I built I managed to install the mosfet driver chip backwards. I looked at the pinout and didn't think out would have killed the chip, but I cant get any voltage reading on the power connector. I have 7 more attempts left.

2018-05-21 16:24:25 +0000 UTCIn that PSU there are multiple transformer taps that can be used to operate efficiently. The current limit happend to cause the voltage to drop all the way into another transformer tap, so it switched back and forth all the time. But there actually are older power supplies that use relays as inverters

2018-05-21 16:13:30 +0000 UTCDoes your PSU use a Relay to regulate current!!? It's so loud 😂🙉
