Forum user Christian, writing from Germany, posted this video of an automated system he built that pushes buttons on a car radio (Becker Mexico CD 876) as a brute-force method to determine its radio code. In his system, he uses our Mini Maestro 12-Channel USB Servo Controller and 10 servos to extend rods of wood to press the numbered buttons on the radio console. You can read more about his system in this forum post.
The setup had already run for 3 days straight, but Christian expects it to take another 30 days to finish entering all 10,000 codes. We look forward to hearing back from Christian once it finishes.
