Zero bugs, maybe.

A project log for Team Ides: DC27 / da Bomb!

A wearable, hackable, blinky badge for Defcon27 featuring RGB leds, sound, BLE, games, and more!

Our schematic passed DRC checks last night and today I've been bouncing back and forth between Mouser, Digikey, Alibaba, and the MacroFab House Parts List trying to check all of our footprints before we go into PCB Layout mode.

Our BOM currently contains about 133 parts per board-kit, and our BOM cost is much lower than last year thanks to the use of fewer through-hole parts (moar SMD!) and getting away from expensive parts like the WS2812B's.

Speaking of which, it's been pretty difficult to pick a board shape and design! (Dragons? Submarines? Triemes?)

When we did the badge for DC25 the obvious choice was Roman Something... but now that we're a couple years in and DEF CON is going to be spread across multiple hotels again, I don't know.

Because we've got BLE on the badge this year, and I wanted to do a Greek Naval battle game, I'm thinking of making the badge into a ship, but I haven't really decided yet. I think the plan for now is going to be do make it square so we can get our electrical tests done, and if those pass, we'll move on to fancier board designs. 

More updates this weekend, for sure.
