I am a student. How can I learn new things while making a TINY bit of money?

I'm just a student, and my goals aren't very high. "Get rich quick" schemes are ludicrous! I'm talking a hundred or two a month. Mostly I just want to learn. I'm not planning to go into business or startups, so I'm not looking for an enormous resume-boost either. I'm overflowing with ideas but most of them are extremely complex and would require an enormous initial investment and months of full-time work-- while I'd love to pursue these in the future, right now I just want something interesting that will help get me by. I'm not sure if I'm asking for (general) ideas or advice, so I'd appreciate anything you could offer.
