DIY Intervalometer for Canon & Nikon


Completed Intervalometer from Otter Creek

This is an unusual item that Canon and Nikon photographers might find useful – an intervalometer! An intervalometer is a device that will permit the photographer to set the camera to take a series of images for a set interval. A common use is for time-lapse images of flowers opening, etc. Well, you can do the same thing with you DSLR from Canon or Nikon (others too, with the right adapter). This intervalometer is actually a kit which is available from created by Otter Creek (
Features of the CT-1 intervalometer include:
– Optically isolated interface to the camera
– Standard intervalometer function with options for setting delay time and exposure time.
– Built-in optical sensor for triggering camera with light/shadow.
– External port allows for easy integration of alternate trigger circuits (sound, light, …)
– Manual mode for simple trigger and bulb mode exposures.
– Two position pushbutton for trigger – focus/shutter, just like on the camera.
– 2′ cable terminated with Canon &reg E3 plug (2.5mm stereo)
– Optional cables for connecting with other cameras

For only $60 – and an evening of soldering – this might make a fun addition to your photo toys!!

    I’m going to be posting an update on intervalometers for DSLRs as I believe Otter Creeks may have closed up shop and are no longer available on Amazon either. I just ordered a test unit – so I’ll be posting an update soon!

    Sadly, it looks like Otter Creeks website is down.
