Art With Steppers And STM32

Automotive dashboards are something that largely go untouched in the average car’s life. Other than the occasional wipe with a damp cloth, they’re generally reliable for the life of the car and considered too tricky to repair as age sets in. Nevertheless, some hackers find themselves tinkering with them, and learn skills in the process, such as how to control stepper motors and talk to the CAN bus. Having done some projects in the past, [Dan] had some old tachometers lying around and decided to turn them into a piece of art.

The build is powered by an STM32 – a powerful ARM-based platform with plenty of IO and potential. [Dan] leveraged its capabilities to have the board generate music and react to its onboard accelerometer data while also driving the stepper motors from the old tachometers. The project was then completed by 3D printing a mounting plate and placing the tachometer assemblies into the back of an IKEA canvas print.

The end result is a piece of wall art that emits eerie stringed music while twitching around. It came about from [Dan]’s prior projects in working with dashboards. It’s a fun use of some well-earned hacking skills, but we reckon there’s even more potential. There’s a huge number of projects that could benefit from lightweight tiny actuators, and we’d love to see a robot made entirely out of junkyard dashboard parts.
