Use 4017, it can operate on 3V and then a transistor oscilator, or the cmos version of 555 which i think is the 7555.

or you can use another cmos ic like 4013 wich can go to 3V and make an oscilator, but there is another thing, the minimum suply for these ICs is 3V so you must have at least 3V. the suply mustnt go below 3V!!!

Thanks guys.
After posting I went back to the first circult that I tried,using a 74hc04 Hex inverter, and found that the reason it was not working was because I had connected one lead to the WRONG pin(no more late night projects).
