Well well well. What is the first thing you do after you have first populated your circuit board? Test the power supplies!

I hacked together a barrel jack connector and an ethernet cable, found out which wires were connected to +12V and GND on my board, and soldered it up. I just used a +9V wall wart.

All the power supplies test good, the LED lights up, and nothing overheats. That's all for today.
