I was hoping to get some ideas about how to make extra money. I'm currently working as an undergraduate researcher for next to nothing, it allows me to pay rent but only barely. I need to make some extra money so I can do extra-curricular things. My background is computer engineering, with an emphasis on electronics, I have experience with Java, Python, and basic knowledge of HTML 5, C. If you guys have any ideas that would help me to make some extra money while using my current skill set that would be greatly appreciated.
With your knowledge/experience, you should easily be able to find work through one of the freelance developer sites out there. It would let you work flexibly on your own schedule, and you can decide what types of work you're willing to do at rates you choose to work for.
You could always come up with your own ideas for a commercial website of some kind that could help generate some degree of passive income that won't interfere with your full-time work. That's only limited by your imagination and creativity.
The third alternative is to find a "real" job (I chuckle at that one!) like most people do.
I hope this helps.
