Here are some photos of the relay boards I have been assembling for my relay-based art projects. Each relay is 12V 4PDT and has an LED to indicate if it is energized or not. The back of each board has solder pads to allow manual wiring of the relays to configure them as needed.

Why the relays? Because they’re noisy? Or because they’re bright yellow? They do look cool.

Geoff thanks for the comment. See my latest post on this for more information.
Cool project. I’m working on some relay computing projects myself.
