Learning new things and building new projects. Mostly we'll hope for the best but we learn from our failures.
Figured I'd share what I learn about some new projects. The main reason is a lot of times I'll find videos with a crucial part of the information missing. Probably not a problem for people familiar with a topic but can be tough on someone starting out.
Made alternating flashers for my kids 4 wheeler. Used a 555 timer because I had a ton of them around. The circuit I used can be found at: http://www.555-timer-circuits.com/flashing-railroad-lights.html
