I have never done any mechanical work before and I am having fun and learning a lot. I highly recommend it as an alternative to starting yet another project.
When I don't feel like working on that or am waiting for parts, I am building an original arcade game. Its in the really early stages but I hope to house it in a traditional coin operated arcade cabinet painted with original artwork from a local artist and put it in a local coffeeshop or something.
I don't have a site to point anyone to for either of these projects.
