We have written instructions for building two sweet microcontroller-based electronics projects for the holidays: an alphanumeric LED christmas tree ornament and an LED mini-menorah (hanukkiah).

These are open-source projects; You can download and modify the source code, use it to program your own microcontroller, and solder the microcontroller to some LEDs to help make your own holiday decorations.

If programming microcontrollers is not your idea of a good time, we understand. Not everyone has (1) access to a microcontroller programmer, (2) the time and (3) the desire to modify the firmware of their christmas tree ornaments.

Low-cost open-source holiday project kits brought to you by Evil Mad Scientist Laboratories.

In order to help our fellow citizens Evil Mad Scientists with their holiday projects, we have put together electronic soldering kits for these projects. (Updated: November 2007)

LED mini-menorah kits are now available at our new web store.

Kits for version 2.0 of the open-source LED Micro-Readerboard project are now available at the Make Store.
