NESblinky - Nintendo Controller Bike Flasher

Step 9 Flasher Circuit

I was trying to use the simplest LED flashing circuit I could find. The Flip Flop circuit at the bottom of this page seemed perfectly suited: http://www.talkingelectronics.com/projects/FlasherCircuits/Page83FlasherCircuitsP1.html

However, I did not have the right size capacitors, and could not get any capacitor/resistor combination to work. The circuit below shows the values that I used. This was based from the circuit found here: http://www.zen22142.zen.co.uk/Circuits/Misc/flasher.htm
If you have any insight on how to make it work, please let me know. Is it because 2.4-3 V is not enough voltage?

I may give these circuit a try:

This circuit is interesting due to it's simplicity and unconventional use of a transistor. However, I do not know if it will work at less the 10V?

I did not have enough time to get the flasher working before I had to leave on a trip, so for now the lights are always on. I will work on the flasher circuit when I return and update the page.
