INTVAL3

What is this?

INTVAL3 is an open source intervalometer for the Bolex 16mm camera. The goal of the project is to create a cheap-to-make intervalometer that can be used to automate time-lapse or animation on the Bolex using mobile, web or physical controls.

This is the third incarnation of the INTVAL project, this time utilizing the Raspberry Pi Zero W for Wifi and Bluetooth control. Earlier versions, the INTVAL and INTVAL2 were Arduino-based. The original INTVAL used a solenoid (!!!) to hammer a camera release cable, while the second attempt was a proving ground for the motor-and-key hardware used in this version.

The INTVAL2 project should be used if you prefer a simpler, physical interface approach.

Components

  • Firmware for the Raspberry Pi Zero W running on Node.js
  • Mobile/Web/API for controlling device, using Cordova + Bleno, and Restify
  • Hardware files, parts models for 3D printing, laser cutting and CNC
  • PCB design for a Raspberry Pi Zero W Bonnet
  • Parts list
