Build your own open-source Bitcoin signing device with a Raspberry Pi Zero, camera and display! We have kits for 45€
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 lashing 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 already soldered
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
