Seedsigners are open-source DIY signing devices which can be built using "normal" hardware like a Raspberry Pi and act as kind of hardware wallets to sign Bitcoin transactions. Since the hardware is missing a secure element chip, the keys are saved externally, usually via self-drawn QR-codes which are read again for every use via the build-in camera.

We brought a few kits with us which we sell for 45€ and build together. We will solder the 40pin GPIO header to the Raspberry Pi Zero, flashing the firmware on the MicroSD card and then build everything together in the 3d-printed enclosure.

The kit includes: Raspberry Pi Zero 1.3 (without Wifi or Bluetooth chip), GPIO-header to solder Display-Hat with joystick and buttons Camera 64GB MicroSD card MicroUSB to USB-C cable 3D printed enclosure 6 printed templates for self-drawn QR-Codes
