Photo Booth

Requirements

• A Laptop
• A Camera that is compatible with gphoto
• An Arduino
• A Force Resistant Sensor (FSR)

Getting Started on macOS

• Install gphoto2 on macOS (See here for instructions)
• Connect the camera to the laptop using an appropriate USB cable. Verify the connection with the command gphoto2 --auto-detect. Connect and unconnect the camera to see the port list changes.
• Try to take photo through gphoto2 and command line with the test_gphoto.sh script. Change port parameters accordingly
• Construct the Arduino / FSR unit according to a schema (To be updated)
• Flash Arduino with a Firmata firmware that is compatible with JonnyFive (See Johnny Five docs for detail). For Arduino UNO, it's the StandardFirmata Plus.
• Clone this repository
• npm install
• Open two terminal sessions. One running npm run arduino
• Another terminal runs npm run dev
• Goto http://localhost:3000 and try to step on the FSR.

Cameras tested

• Nikon D5300

Troubleshooting

• gphoto2 responded with PTPTimeout: The transfer of image to your computer might have taken too long. Try reduce the size of the image in the camera.
• gphoto2 cannot connect to the camera: Some machine will have a default PTP service running. Try disable that with the kill_default_ptp.sh script.

Fine tuning

The force threshold for activation could be set in arduino.js
