Hey, those are some pretty cool little bots! I’m glad I could inspire you, but I think you surpassed me!
I had an issue with the batteries on mine, by the way. The individual cells from the 9V rechargeable weren’t well sealed. They dried out and stopped working within a few days, even though I wrapped them tight with electrical tape. I should replace those batteries for all the bots I gave away that year!
If anyone is interested, here is my post that Gonzik is referring to, which includes links to the original Instructable and the circuit I actually used from Evil Mad Scientist Labs.
I was lucky Energizer makes good batteries, mine have been out for a couple weeks and seem to work great =) I doubt I surpassed you ignoblegnome - we’re on the level I love the glasses you made for Arnolbot and the personality Cheifbot has.
