A good way to make money I found is on computers. Wether it be ebay, programming, selling the part, or building them, you can always find a way to make easily 50$ an hour.

If you know anything about programming flash animation and such, you can make a flash game and submit it to kongregate.com. They hand out prizes weekly and monthly with weekly up to 150$ and monthly about 1500$. People will also pay you to design web pages and other neat things for them which can fetch about 500$ per task. Programming is hard to learn when your first getting into it but if your good at math i recommend doing this.

If you know about computer software and hardware, people will pay you for your knowledge on fixing computers. As long as you know the right commands you can fix any software problem with minimum effort on your part. Heck, most of the time is spent waiting for the computer to finish the task FOR YOU. This is a hobby you should defiantly be getting into if you want to make some cash from time to time.

Another good computer based business to get into is buying part and assembling them into working computers to sell. The parts can cost up to 200 but you can make about 800 on the computer once it is complete.
