John writes in with a how-to on making a Nikon D70 IR remote control –
“This is just the thing you need to have in your camera bag. I have one that I bought online but if your not in a rush and have the skills to solder this would be a clever little device to have around. Very handy for tripping the shutter when your doing macro work or your doing long exposures where camera vibration is a bad thing.” – Link.
