Finished build

2019 DEF CON Car Hacking Village badge

A wearable, working electronic badge shaped like a clear acrylic SUV. I designed the board, the circuit board doubles as the car’s chassis, and the acrylic body is laser-cut. I did much of the design of the acrylic body, and the owner of Specialized Solutions finished the internal structure. About 350 units were built; I designed the board and assembled them.
