Camera Shutter Tester for ESP32 (case and mount)

This github project (not owned by me) provides the firmware for a camera shutter tester, running on an ESP32 board. I created 3d models for both a laser/sensor mount jig and a controller box that are compatible with this project.

The jig uses a set of rails which allow you to adjust the horizontal position of the 3 laser/sensor pairs so it can be used for 35mm cameras all the way up to 6x7 cameras.

Note that the sensors are facing the wrong direction (which makes cable routing easier), so you need to print the white (or probably red) cap to reflect the laser light back to the sensor.

For the rails I provided two versions - one that doesn't require separate supports, but creates tiny bridges instead that you need to cut out with a sharp knife.

I used this hardware:

• ESP32 Development Board NodeMCU-32S 30Pin Board (CH340C, Type-C)
• DIY Kit 1x4 4 Independent Key Button Keypad
• 320x480 SPI modul 4.0/3,95 zoll TFT LCD display Module With Touch
• 4x 5mm M3 screws for the buttons
• 4x 12mm M3 screws for the lid/display
• GX16 Aviation plug and socket (5 pins minimum)
