This is the prototype of the tie pin we plan to make for our own little Learn-to-Solder sessions. It’s inspired by the Makershed tie-pin. We don’t have any RGB flasher LEDs at the moment, and won’t in time forb BarCamp. But the red LEDs still look pretty cool.
At some point we’ll put an order out to a real PCB shop and get a circuit board with red solder mask and black silk screen. But these boards are plenty of fun for now.
