Skeleton Surprise

myminifactory

A spine-tingling skeleton surprise swoops down on unsuspecting visitors! Muwahahaha! A motorized pulley and quick release mechanism quickly drop a skeleton in front of trick-or-treaters, then raise it back up to scare another visitor. (A LEGO Mindstorms EV3 kit and some additional LEGO Technic parts are required for the electronics of this build.) The picture shows the orientation of the 3D printed parts as they will be assembled (without the required LEGO parts). To assemble this project, you will need: String (the amount varies on how high it is mounted and the amount of travel desired) One EV3 or BrickPi One M motor One L motor Two LEGO axles, some LEGO gears, and a LEGO gearbox gear with the clutch engage feature https://www.google.com/search?biw=1680&bih=806&tbm=isch&sa=1&q=lego+clutch+gears&oq=lego+clutch+gears&gs_l=psy-ab.3..0i24k1.9393.11966.0.12061.13.13.0.0.0.0.100.1019.12j1.13.0....0...1.1.64.psy-ab..0.13.1016...0j0i67k1j0i30k1j0i5i30k1.0.Q7HHdvDsVUM#imgrc=ggU1oAhzoZwfSM: This object was made in Tinkercad. https://www.tinkercad.com/things/6r5R7qzwukF
