Todbot has more photos and a 3rd Roomba Bluetooth interface, he writes – “The case is a Hubble-Bubba bubblegum container which contained about a meter of uncut blue bubblegum. I tried some of the gum and it was pretty gross. But the container was cool, looked a bit like the Roomba and was blue, so it obviously must become a Roomba Bluetooth adapter.” Link.
