this kit doesn't use the 555, just a couple of transistors instead, but it's very close to actual flash rate, and the kit is less than a buck for all parts, including the pcb and shipping ..
The circuit you want shown above is a simple two transistor push-pull oscillator.
RC value controls the rate. 555 is overkill, you can wire the above circuit with a small piece of perfboard and power with a 9 volt battery or a wall wart.
