Make your own CDI!

CDIs(capacitor discharge ignition) is what makes our spark plugs spark, but it's rarely mentioned how they actually work.  I bet most of us didn't know that making your own would be practical, but it turns out the CDI is a relatively simple piece of electronics.


Rohmell from motorbicycling.com found some CDI schematics and decided to replicate them in reality.  If you'd like to venture into building your own CDI, check out his thread for more details!
