Couple of Inchworm HEX Bugs showed-up recently on my workbench and they were a lot of fun to play until we have drained the two L1154 button cells that power it. The simple way to extend the fun (for a bit more!) is to swap the batteries from the remote control but it is only a temporary solution. Once the inchworm stops moving the only option is to get more L1154 or is it? The plan is to hack these little creatures and give them some real power and extra smarts!
