Hot shoe rangefinder

thingiverse

Camera Rangefinder designed for improving consistency in photogrammetry scanning. Uses Arduino proMicro, HC-SR04 Ultrasonic Distance Sensor, and 7 segment backpack. Concept from Erik Christensen who came up with the idea of adding a distance sensor for improving photo range consistency.

After building this and using it outside, it turns out the 7Segment isn't very bright so I added a V2 lid that adds a bit of a lip.
