Three years back in time, I bought Nikon D3000 DSLR. I started shooting, but the moment I needed remote, came one day (more over night), during on night photography session. I checked all local suppliers, but the prices were high. I ordered one from China. The problem with orders from China is that they take time. I started waiting and one day I made my IR remote, using the MSP430.
This is a youtube video showing the remote in action:
