I was wondering if anyone had suggestions for intervalometers for a Nikon D90. The D90 lacks a remote port, so it has to be triggered either by USB or IR, which limits the 3rd party remotes it is compatible with quite a bit.

  • Ended up making my own. A fully functional one can be put together for about $10 with a little bit of electronics knowledge. Everything else available seemed way overpriced for what they did.

The Nikon D90 can in fact accept a wired remote. It plugs into the GPS port which is the second rubber-covered area on the side of the D90. While some cameras have separate ports, the D90 uses this single port for both purposes.

Here are a couple options from Amazon:


I ended up making my own using some slapped together electronics. Personally I think this is the best option considering how overpriced everything else is.

The setup is very simple. I use a TI Launchpad with an MSP430G2231 to generate the IR signal. It's a $5 solution that is very flexible and I can set it up to do just about anything I need.

Here is a link to the schematic: Link to schematic :) (link broken)

  • Can you write up somewhere what you did?

    Right here in the answer would be a nice "somewhere".

  • +1 for @Evan as I too would like the schematic and overview to build my own

  • Looking forward to the writeup.

    I too built my own using the Arduino platform but it cannot go beyond 1/3 shutter speeds in bulb mode. So IR and CableTrigger only good for timelapse style photography (which is where the intervalometer shines!)
