Check out Daryll Strauss’s Digital Dominos:

I revealed the Digital Domino at the CrashSpace booth at MakerFaire this year. It’s a small electronics kit that allows users to line up virtual dominoes and knock them over by pressing a button. Each domino lights up an LED and uses an IR pulse to knock over the next one. They can also be looped to repeat the pulses. We won an editor’s choice award at MakerFaire for them.

These were designed to be very easy to hack. The timing can be changed, the lights can be changed, they can be used to trigger other devices, they can be triggered by a microcontroller, they can sound a buzzer, etc.

    Randy Elwin’s Le Dominoux (http://www.youtube.com/user/dirtypinball#p/a/u/0/PQOjkuJtBfM) seem a little more elegant that this. Elwin was a 555 contest winner.  In particlur I like Elwin’s use of a paper clip for the battery holder.

      We started with Randy’s design (and credited him for inspiration in our About page). I feel like we improved it by lower the cost, making it easier to build, making it consume less power, and making it more reliable.

    Randy’s design was great, especially the paper clip battery holder. Daryll’s change to a “commercial” battery holder made it sturdier, and the use of IR lets it work in bright light, which is a real plus.

    Domino’s has always been great to me, I
    love their new ingredients, but I keep coming across stories of
    people who have had really bad experiences with them, there are some
    really funny vents about them here>.
