DIY Headtracker Arduino NANO33 BLE (SENSE)

thingiverse

This is a housing design to be used with the open source head tracker from https://github.com/dlktdr/HeadTracker. My goal was to use it for both my Fatshark and DJI goggles by simple attachment with velcro. You can use either the NANO33 BLE or the NANO33 BLE SENSE board. The top part provides the holes and internal optical shielding required for the proximity sensor to work correctly. I used a 6x6mm micro push button for re-centering the tracker (works in parallel to the proximity sensor in case of SENSE board). While the front side of the Fat Shark goggles is flat, a simple piece of velcro will do. In contrast the DJI goggles have no flat surfaces. So I took some self-adhesive and stiff rubber plate as base for the velcro. Even if it is not really flat, this will work good enough.
