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. Erik Christensen came up with the idea of adding a distance sensor to improve photo range consistency.

After building this and using it outside, I realized that the 7Segment isn't very bright, so I added a V2 lid with a bit of a lip to improve it.
