Supercon 2016 blinky. I walked in on people hacking their badge and got immersed in hacking my own! Found a table full of supplies and went for it.
Badge pwr + transistor + relay + 9v + leds + hot glue. LED on/off = up/dwn badge buttons. It was a fast build, not the prettiest.
Sooo satisfying. ::click:: Lol. Thanks Zach. Honestly after watching you hack your badge, I felt inspired. I thoroughly loved how you built your larger display. Very unique and creative.
Definitely one of the better ones, in my opinion. Nothing better than the feel of a relay in your hands.
