I've developed a remote control for my D70 digital SLR camera. I have built a protototype which is pretty functional. Contact me if you want more information.

Features

• "standard" shutter release, just like Nikons ML-3
• programmed shutter release, i.e. "take a picture every n seconds"
• programmed bulb release, i.e. "take a bulb exposure with n seconds exposure time"
• an LCD and some navigation buttons to control the whole thing

Technical Details

The remote control is based on an AVR Atmega16 microcontroller. I programmed the firmware in C (avr-gcc). The D70 is controlled using an IR led modulated via a PWM port. I got the timing diagram from here. The device is powered by a 9V block using a 7805 voltage regulator to get the 5V. I might replace this by a more powersaving solution if I see the battery draining too quickly.
