Documentation and Software

To download binary (executable) versions of the software, go to:

For the documentation, please visit:


All software files are licenced under GNU GPL v3.

All hardware files (schematics, PCB) are licenced under Creative Commons 4.0 (CC BY-NC-SA).

Building from Source

I use Qt Creator to build the software interface. Open Desktop_Interface/, then Clean All -> Run qmake -> Build All. If you're on Linux (including Raspberry Pi), then you can also build the software from source by cloning the repo, cd'ing to the Desktop_Interface directory then running:

sudo make install

Then, to launch, just type labrador into the terminal.

To build the AVR software, I use Atmel Studio 7. Just load up the .atsln and push F7. You can use avr-gcc if you don't want to install a full IDE.

The PCB files can be edited in KiCAD 4.0.

Known bugs.

Most of the main bugs have now been fixed, including all synchronisation issues. Please open an issue if you're aware of any in particular.
