Maker QT31416 has created a customized 3D printed cryptocurrency hardware wallet, which is created by Raspberry Pi Zero WHIt functions much like Trezor hardware wallet, but it is cheaper to use Raspberry Pi (and arguably more interesting).
The biggest problem we encountered when considering this project was safety. The official Trezor wallet does not rely on SD cards for storage, while Pi Zero does. To prevent unwanted people from accessing your wallet, the creator of PiTrezor recommends using a password to protect data.
This The best Raspberry Pi project It is a project that you can recreate at home, and this project is no exception. QT31416 shared everything needed to get started, including the original version Pietrezzo A tutorial and a complete parts list that inspired the project.
The design of QT31416 uses a 128 x 64 OLED HAT installed in a custom built interior 3D printing case. To navigate the UI in this project, QT31416 uses the button 2 button and joystick button attached to the HAT. The PiTrezor firmware relies on the left and right buttons for selection, which can be easily adapted to the joystick input.
