I'm looking to build a wave pendulum such as this one:
I was hoping to build one with 14 balls with magnets on the bottom, and use the Arduino Mega 2560 to sense a ball coming close and then a kicker circuit like this one: http://home.earthlink.net/~lenyr/magkick.htm
to impart a kick via electromagnet (I was planning on building 14 electromagnets, one to go under each ball).
Is this a project that is doomed to failure, or do you think it's feasible? It doesn't matter to me if I have to initially start the pendulum by hand, but after it begins running, I would love to be able to modify its path by adjusting the amount of kick given to individual balls.
If it were to work, other ideas down the line include incorporating motion / light sensors to trigger various patterns, or even synchronizing them with music, or simply generating new patterns randomly.
Any tips or advice you may have are greatly appreciated. I apologize if I'm a little under-informed, but I thought I'd just check first off to see if this is a pipe dream or not before delving into the nitty gritty. Thanks a lot, and if I start on this, I'll definitely keep you posted.
