Building a homebrew generator

A few years ago I built my own generator. I cobbled it together with some parts I had laying around the house. I found a free lawnmower on craigslist and I used the engine from it as a power source for the generator. I coupled the engine to an automobile alternator and a power inverter. The result is a cheap AC power generator. It only produces a few hundred watts of power, but it’s enough to power lights or emergency equipment in the event of power failure. I did this project for fun, not as a replacement for a real backup power generator. Here are some pictures:
