I found a great way to make money for projects! You can develop iPhone apps! I'm not sure how much it costs to submit an app, but I know you have to pay $100 to sign up. You have to have a mac. It is hard but it's really cool! I'm working on an app! If you don't know how to use it, I would suggest looking for an app called "how to make your first iPhone app".

Maybe this will make robotics more affordable...
