This repository includes schematics, code, and instructions for building our hardware clone of the device from Steel Crate Games' game "Keep Talking and Nobody Explodes".
The code is written for an STM32F4 Discovery board, which you can probably get for around 25 €. The rest of the materials probably cost another 25 €. A complete list of required materials can be found in the material list.
There are also complete KiCad schematics in the schematics folder, along with some assembly tips. v Our cube design requires 8 corner pieces, which you can 3D print from this STL file (Designed for 6mm M2.5 screws with nuts. I lost the OpenSCAD file but I'm sure you can remake it pretty easily).
If you want to mess with the code, take a look at the architecture description.
Lastly, there's a quick reference how to play the game.
The code does not use any libraries and requires only a GCC compiler and linker to build (prefix arm-none-eabi).
It can be uploaded to the board via USB using OpenOCD and the GDB debugger.
To read the console you will also need a 3.3V UART adapter.
From the repository root folder, run
make
openocd&
arm-none-eabi-gdb -x .gdbinit
Use the reload command (defined in the .gdbinit file) to upload the software.
