I’m using a 12V power supply from the computer - the black and yellow wires from the Molex connector.

This is my first stab at making this table. I’ve learned a lot, esp. what I will do differently next time. I’ve made a note about the LM317. I’ll try it next - either my second table (FTIR - DI hybrid!) or if these LEDs go paff!
