You could try freelancing. The pay's usually not that great unless you keep at it, but it's something. I went through a rough spot a couple of years ago and made money as a freelance programmer and translator, and I'd look for really cheap deals at yardsales and then sale them on Craiglist or pawn them. I was homeless sometimes but I always had a car and it wasn't all that bad. I was making around $500 a month for a while and basically my only charges were: Starbucks coffees so I could do my job on their free wifi, a gym membership so I could take showers, a little bit of gas, cheap food, prepaid phone, and a couple other little things.
