LED glow sick - A hack to make it flash
Hi I have bought a LED glow sitck. The type used in cars for "effect" lighting. I am using it on the back of my recumbent bike. However I think it would create a bit more safety for me if it flashed. It currently runs off a small 12 volt battery. I have looked through instructables to find out if there is anything already written up. However my knowledge is very limited, so I am uncertain if I could use some of the circuits described. I can solder okay and that is about it.
So my burning question is how do I make a circuit that will flip the 12 volt power supply to the LED's on and off. Alternatively are there circuits already on instructables and I just have to build and run 12 volts through it ( and it won't destroy the light stick). I dealy I would like it to flash on and off fairly rapidly. Any assistance would be appreciated.
