Now that the puppets are almost finished, I can get onto the most important bit - adding the Jaw-O-Meter! I've made it green like Ruby's drawing and thought it would probably attach to the face around the ears so have added some straps. Where the teeth wind up - I've made some little wooden cogs to go over the handle. If people wanted to power different devices with the Jaw-O-Meter I thought it would be sensible to have the mask plug into a main transformer box which the devices would be attached to. This could also show how much power is being generated with some kind of dial.
