Electronic conference badges are cool and everything, but they're A LOT of time, money, and effort including but not limited to hardware, software and art design, testing, manufacturing, testing, provisioning, and repairing.

I've got a relatively simple, cheap, mass-producible badge design. We'll start out by looking at and understanding the design and implementation, highlighting the areas worth customizing (and which to leave as-s). Then we'll spend the majority of our time working in KiCAD to customize the hardware, CircuitPython to customize the software, or both if you have time.

We'll wrap up with some discussion of how to handle badge logistics for events of different sizes, and warn about some of the many pitfalls that electronic badges suffer. You should walk away with the design for your own customized badge design plus everything you need to have it mass produced.
