Badgebit turns a Digispark (tiny AVR device) into a Wiegand/HID-compatible badge access control device.
Features:
- Wiegand-compatible 2-wire reader interface. Supports many devices (ie OmniProx OP40, ~$30 on ebay).
- General-purpose output triggered on badge recognition.
- Can be used without a host computer (standalone mode).
- Single-button "learn mode" for storing or clearing known badge IDs.
Potential uses:
- Badgebit -> Lockitron -> Unlock home door
- Badgebit -> usb-serial-for-android -> Self-checkout kiosk
- Badgebit -> Raspbery pi -> Relay board -> Garage door opener
Board schematic and layout are on Upverter.
Arduino/Digispark-compatible program is in this tree.

Upverter is a Bay Area tech startup that makes an online EDA tool.
We were interested in trying out their tool, so we entered their hackathon and came up with this contrived project as something possibly feasible in an afternoon.
