The Open Hardware Summit is coming on Thursday, September 27th at MIT.  OSH Park and Screaming Circuits are producing an electronic conference badge this year for the Summit.  The badge features an e-paper display and an ESP32 microcontroller.

 

The OHS18 badge also features the DefCon 26 #badgelife add-on header.  Andrew Sowa designed this OSHWA-themed Learn to Solder add-on board to connector the badge add-on header:
