online engineering job hunt

Hi,
I am 3rd year electrical engineering student. I would like to earn some money with my knowledge but as I still study I can't search for full time employment so I would like to ask if anyone of you knows some site where occasionally jobs could be found. I have found www.rentacoder.com and it seems good. There are some projects that have to be done and you can work from home. I would be really thankful if anyone could direct me somewhere.
Thanks,
Niko
