Finally added some more lights to the P1S. Relay controlled from USB-A port.

Trickier than I thought as the original light seems to be controlled by a NPN transistor which threw me off when using the 0V from the USB-A. Feel free to ask if you want to know how to do this yourself without risking burning your board.

Huge upgrade for very little money.

Thank you, mate!

I was considering running it switched with remote power, but the nerd in me wanted to cut wires, solder and "automate", it that makes sense.

I guess I will regret it the next time I need to do some work with my head inside the chamber hehe.

Oh I totally get it, and probably would’ve gone that route if my DIY skill level was higher. My benefit of maintenance lighting is a lucky accident. 🤣
