As soon as I heard about the 555 timer contest, I knew I had to come up with something inspiring! My buddy Jay recently introduced me to Nixie Tubes, and I thought… hmm, how can I use a tube and the 555 timer? I noodled on it for a while, and ultimately came up with the notion of a KEYCHAIN! Simple really, take the smallest Nixie Tube that displays digits, and make it display a ’5′ in the smallest package possible and put it on a keychain. That was the idea… and it took quite a journey to complete.
