The Blinky kits were developed with Kicad, an open source electronic design suite. It is available for Windows, Linux, and OS X.

All our source code is also available in the Wayne and Layne GitHub repository.

The software that runs the Blinky kits is split into two parts, the bootloader and the regular, “user” code (more details). The bootloader is only used for loading new messages into the kit’s EEPROM memory, but can’t display any messages on the LEDs. The user code is used to read messages from the EEPROM and display the messages on the LEDs. You need both parts for a functional kit. We have created “combined” hex files that include both the bootloader and the user code. If you have access to a PIC microcontroller programmer and are trying to fix your Blinky kit, you probably want to start by programming one of these files to your Blinky kit, as it will reset the microcontroller to its “factory reset” condition. You can also download either the raw source code (ZIP archive with build scripts) for the bootloader and user code, for both Blinky GRID and Blinky POV.
