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.
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.
