thingiverse
This design is a game-changer for digital programmable timer relay, which turned out to be a super handy little gadget. You can use it to flip electrical devices (AC or DC) on and off at programmable intervals, or when triggered by a switch. I put it to work programming a time delay into a vapor polishing chamber project.
