Okay, sometimes robot technology reallocation can provide rewarding results...even if the effort is less than stupendous.
That said, I have re-used my electric-wheelchair hack technology and applied it my ever-morphing holiday bots. Today's submission - Donna the Dead - "one mad bride that goes for a ride".
Using "low-tech" Home Depot pipe technology (tie-wrapped to her head), she seems to float though the chilling evening sky -- moaning at the mad scientist who wired 5 volts into her "Party City" vibrating scull. A $10 strobe running from a 12V scooter battery inverted to 110VAC makes sure she's noticed, and the 110V makes for easy use of a wall-wart to send 5 volts up the flat-black pole.
Spread spectrum dual channel RF technology insures she won't stray. The AVR code, that taps into the wheel-chair pot electronics is freely available at www.thespiritedtree.com and also was first posted in Trossen forums. Hope ya like her.
