My original vision was to create a mechanical video game that would light up LEDs. Then I started tinkering with fischertechnik's Eco Power kit (#57485) and realized that my first step would be a simple explaination of how to use LEDs with fischertechnik models.
I play with different educational manipulatives for a living. (Visit www.weirdrichard.com and www.edventures.com). Over the years I have built different models using all sorts of toys, and I have created many different electronic based devices that use LEDs.
Step 1: Collect the Parts
I limited myself to the Eco Power kit (#57485).
