TechnicBrickPower Posted June 2, 2021 Posted June 2, 2021 Hi there everyone - here's a video I did recently. This Lego Technic project was to design a demonstration unit for the Fantom Wallet - a slimline wallet for holding credit cards. The mechanism opens and closes the wallet uses a 4 state cycle based on an earlier design of a 4 state multi-function gearbox (https://youtu.be/AdWiViLtmdk) that switches between two outputs using the reverse directions of the motor for state changes. That gearbox drives one output at a time in either the forward or reverse direction which was exactly needed for the Fantom Wallet opener. One output drives the opening mechanism and the other output drives the closing mechanism. In the opener the states are driven by the orange rotary catch component and changed by one length 2 liftarm driving another and using a 90 degree stepper. Quote
