Here's the resulting circuit, hurriedly made on a breadboard. It's sloppy and ugly, but I don't care. The circuit worked exactly as designed. You'll note that the original circuit we worked from lists a 2.2uF tantalum capacitor. I didn't have one on hand, and used an electrolitic capacitor instead, and it worked alright.

You will notice in the video that there is a duty cycle of about 90% (the lights are on 90% of the time, and blink off for 10% of the time). This is due to the external components (resistors and capacitors) attached to the 555 timer. If you're interested in changing the duty cycle, please review th links I provided earlier. If there's interest, I'll write up an instructable on it.

Hope this instructable was helpful. Feel free to make any corrections or ask any questions. I'd be glad to assist where I can.
