i felt that it was firstly important to document what elmo was capable of doing, especially beyond notes. i've posted the following video on you tube.
currently elmo is slowly (nervously) being pulled apart, and i will post more info when that is completed.
teletubby vivisection part two
the vivisection of the teletubby is mostly complete. after fully pulling him apart, it was easy to tell how everything worked. i've attached images and an electrical schematic of the wiring.
pulled apart, it looks like a mess.
what's most interesting to me are the correlations between the mechanical systems (mostly gears) and the electronic switches. what i found is that some of the gears inside the mechanism have parts that are designed to set off one of three sensors. two of the sensors dictate the direction of motor, and one turns it off. this is how the mechanism responds to the spool of children on the inside.
