Just a small dual linear power supply using LM78Lxx and 79Lxx chips. Very flexible… just use a center tapped transformer with enough voltage for your regulators, and appropriate capacitors.

Interface board to easily use an ESP-01 with RGB LED strips. I use this for a TIX clock. Board (and LEDs) powered with 5v DC. A 3.3v regulator powers the ESP-01. I also use a mosfet level converter for the data line, though I don’t know if it’s absolutely necessary… better safe than sorry though.
U1 - TPS732xx (whichever one is 3.3v)
Q1 - BSS138 mosfet
R1,2,4 - 10k
R3 - 300-500 (not critical)
C1 - 10uf
C2 - 0.1uf (I've used 1uf for both and it works)

Light bar for under my desk cupboards. I have a bunch of super bright white LEDs that I need to use up and these will help throw light around the desk.
With a 12v supply and 47 ohms for the resistor, I was reading 8ma current draw, and the LEDs were pretty bright.
Apparently there’s a bug with the board outline code so it displays funny on the web site - the 9 boards I ordered all came out fine.
