Wires are so 2017
As a challenge to ourselves, we decided to make the controllers for ClunkerJunker completely wireless to allow players greater freedom of movement. Depending on the exhibition space, the four stations can be set up in several different configurations, forcing the players to maneuver around each other as they try to keep everything functional.
Despite the nature of the game, we're actually quite proud of the construction! Both the controllers and stations were modeled in Solidworks and are made of CNC cut wood. Each repair tool has a 3D printed cap on the end of each dynamo, and a small 3D printed cover for the rectifier bridge on its top. The business end of the tool is a Home Depot sourced copper pipe, and inside sits the DC converter which is wired to, and powered by, the dynamo crank. When engaged, the converter lights up a blue LED, which is read by the photo-resistors inside each station. That light value is then translated into a 'repair speed' depending on how fast the dynamo is cranked. Status LEDs on the inside of each station change from red-orange-yellow-green to indicate the state of each repair. Once green, the panel can be closed the station will function again.
