The Fake Badge

One particular SAO that might be useful either for this badge or the Dumb Badge is an RS-232 conversion SAO. Turns out, that's really simple to do - just one chip and a handful of passives.

I call it SAO 232. It's not really worthy of its own Hackaday project, but I'll throw the board and schematic in the files section here.

DRM-114 is going to be an async serial SAO for Defcon 2019. It'll be designed to go with the Dumb Badge, but it's conceivable that not everyone will be able to get ahold of one of those (there are a lot of folks at DEFCON). So plan B is this - it's the Fake Badge and it allows you to bridge the async serial port of an SAO v1.69bis to USB.
