I will be building one of these myself shortly. I used to have a nice 25 VDC bench top power supply but a leaky water pipe sent it to electronics heaven. The units looks like to needs a load to stay on, that would normaly be the mother board of a PC but in my casse I think I’ll use a 12V neon case light. Should be hard to forget that I left it on with it glowing like a spent fuel storage pool.
