With a very simple bit of workshoppery, and a $5 companion app from the App Store, you can turn you iPhone or iPod Touch into an infrared remote for your Canon SLR camera.
It works like this. The DSLR.Bot application sends a signal to the headphone jack of your iPhone via a third-party IR transmitter that plugs into the jack socket. You buy the app, and then you watch this video, in which the iPhone Guru shows you how to build your own IR beamer:
It’s incredibly simple, involving the jack and cable from an old pair of broken headphones, a pair of 940nm IR LEDs and some “sodder”. I assume this means “solder”, as the “l” is included in the written list at the end of the video.
You “sodder” one LED to the positive and negative wires inside the cable, and then “sodder” the other one in reverse. If you have two ground wires in there, they should be twisted together. Insulate and clean things up with some electrical tape and you’re done.
Pop your new beamer into the headphone jack and point it at the camera. Tap the on-screen button to fire the shutter, or shoot with a two-second delay. You can also bracket, shoot time lapses and long exposures, and even record the GPS co-ordinates of each shot.
The app costs just $5, and the LEDs will run you a few bucks at your local electronics supply store. If you have a Canon DSLR, a “soddering” iron and a steady hand, it seems ridiculous not to do this project, so easy and cheap is it.
