I made a badge this year for the photo team at
@Defcon

I've been quietly working on this for several weeks as time allowed. I love my team and wanted to appreciate them!

Based on an ESP32s3, It's a touchscreen, and the badge is rechargable via USB-C.

The TFT_eSPI library is doing a lot of the heavy lifting here. It's also pulling the GIFs off of an SD card instead of internal memory. The community for the screen hardware is minimal at best so there was a lot of fumbling about getting this to work.

I also cut my own header pins trying to keep the badge as thin as possible. It's also stacked on top of a 2000mah lipo battery and it should run 14 hours on a charge.

The CAD program used to make the case is Onshape, can't say enough good things about it.

Because it's an ESP32s3 the GIFs had to really be optimized to work on the 240 display.

There are more gifs on the badge but you'll need to find one of us if you want to see the rest!

There are slits in the case vertically and horizontally.

The vertical slit is so the conference lanyard can be passed through, and the badge won't require an additional lanyard of its own.

Horizontal slit are thick enough to accept a zip tie and wide enough for velcro strips.
