Haptic control optical filter wheel for a standard servo

thingiverse

This is a filter wheel designed to hold standard 1-inch circular optical filters. It's engineered to be driven by a Futaba/Parallax servo, providing a tight push-fit onto the servo at all times.\r\n\r\nA magnet and Hall sensor were added to enable force-feedback control using a MicroPython PyBoard as the central controller: Users can now turn the wheel manually!\r\n\r\nThis project was a fun exploration of low-cost possibilities for an optics laboratory.
