I have been looking for a way to add external power to my camera for a while. I have had some good ideas and even hacked together a workable prototype a while back. The problem was it wasn’t very ‘tight’ and I was always afraid I was going to reverse polarity, or short it out, and it took a lot of time to set it up every time I wanted to use it.
I used the same wall-wart from before. It is a Nokia phone charger rated at 6.2V 720mA. I soldered on a female plug and electrical taped it into a nice little wire. On the camera side I opened up my battery/intervalometer grip and soldered in a female plug to the + and – battery terminals. It took more time than I have expected it to, but in the end it came out reasonably clean.
Now all I need to do to in order to get on wall power (or big old external battery power) is to plug a wire into the grip! Nothing groundbreaking here, but it will help me out a lot doing long timelapses.
While I am thinking of it, I also found out about this free timelapse app called sofortbild for mac that seems to have almost identical functionality to nikon camera control! I have used it for a brief period of time, and I’m looking forward to testing it out more. Give it a shot!
