Kit Complexity: 4
(1=Easy, 5=Difficult) Is the kit easy, moderate, or challenging to build for its most likely target audience? Kits clearly aimed at children would, for example, be rated differently from microcontroller kits.
Coil Driver
If you like high-voltage sparks arcing through the air (and who doesn’t?), check out the Coil Driver, which drives an automotive ignition coil at audio frequencies. Like other musical kits, the Coil Driver makes a great group build because you can all make cool sounds together when you’re done. However, while it’s an easy solder, […]
