A "business card" PCB. It's supposed to be the best and perfect, of course, so it will be a synth with touch-sensitive backlit keyboard, an integrated speaker, single-sided load (with a design on another side), as slim as possible and running on a coin cell battery. I have no idea what I'm doing, so this is a learning exercise first and foremost
Testing out the idea of casting hot-glue light pipes into 3D prints, directly onto PCB. This is for directing the light from "side-firing" LEDs onto and through the PCB, for keyboard backlighting.
So, it shapes nicely and sticks well. Only I need to use both ports to fill the whole area, and maybe add air vents. LEDs arrived, I can try woth them now!
