For Arduino fans, a printed Las Vegas gambling machine.Three low cost steppermotors (Aliexpress) including a driver pcb, are used to generate random outcome. Insert a coin and the arm becomes active. A jackpot is anounced by a buzzer and ledlights. A magnet in the door is pushed away by a coil, the door opens and all the money present falls out of the opening below. A pcb proposal and an Arduino sample sketch are included, as well as the design files in OpenSCAD. Some details have to be filled in yet. Made for 5 cent Euro coins or similar.Thanks to BobD for the name plate customizer of thing:880672Thanks to the 3D doctors team for the other name plates.http://3ddoctors.net/templates/textsigns/textsign.html
