Project Goals

We are artists following in the footsteps of the DEFCON Badgelife scene. Badgelifers create custom electronic devices to replace the ho-hum badges that display your name and affiliation at conferences. These badges feature playable video games, animated LED displays, wifi connectivity, and more! But what would happen if we released a simple badge template that non-engineers could program and expand upon themselves? Let's find out.

BOM

After much experimentation, we've settled on this board. It includes the following features in one tidy package:

  1. Wifi/bluetooth (via ESP32, the recent update to the ESP8266)
  2. LIPO battery clip/recharging circuit
  3. Arduino IDE compatibility
  4. OLED screen

Design

After flirting with building a project from scratch, we've brought the process back down to earth. Right now the plan is to focus on a cool little breakout for an existing ESP PCB (see BOM) that will allow for the addition of sensors etc. in the form of pluggable modules. The form-factor could even take the shape of a robot or action figure! Once we release the platform specs, other developers could develop their own modules to extend the project's ecosystem. Ideas include:

  1. Co-planar PCB connectors (image)
  2. Hemaphroditic connectors (image)
  3. 5-way tac switch
