Homemade strobe slave

Posted 11 January, 2007 in Camera Hacking & DIY

Photography enthusiast Nick Pagazani was hindered by the range and fixed location of his camera’s flash. Since his camera has no connector for an external flash, he needed a light-activated slave trigger to fire a remote strobe. It had to ignore the pre-flashes used for red-eye correction and fire only on the main flash. His solution: Use a microcontroller to count pulses from a phototransistor and trigger the strobe at a switch-selectable count. Brighten up your shadowy background with this flashy accessory.
