Desmontei Turns TicWatch Pro 3 Into Gear-Knob Display With 2 Functions

Desmontei repurposed a TicWatch Pro 3’s display and motherboard into a 3D-printed gear knob that shows the car’s active gear on the lever itself.
A custom Wear OS app uses accelerometer and gyroscope readings to calculate the knob’s angle and infer which gear is engaged.
Hill driving initially threw off the readings, but he said he fine-tuned the algorithm to reduce incorrect gear displays.
Swipe gestures add a second use: the modified knob can pause Spotify or skip tracks while driving.
A second version is already planned, with stronger SLS-printed material and possibly a second car-mounted sensor for more reliable angle reference on inclines.
