Flash sync port hacking


Reader [Adrian] picked up a couple cheap wireless flash triggers on eBay. Unfortunately, his Sigma EF-500 DG Super strobe doesn’t have the necessary sync port to make use of these. He popped the device open to try to figure out a way to trigger the device manually. The first idea was to use the test button to fire the device. Thanks to lag, it didn’t work for anything under 1/20th. The solution was to go straight for the optical trigger. [Adrian] has posted some teardown pictures that will help you determine the appropriate solder points for your own mod. The only bit that’s left is adding a 3.5mm mono headphone jack as a sync port. He also has a post on modifying the flash for greater head movement.

    …I guess I’m not the only hacker around these parts with that name. :P

    One day, this Adrian will have a hack on here. That is one of my big goals, believe it or not. I hold this blog in high regard.

    As for this hack…If I can figure out what I would need wireless flashes for, I would totally do this. Interesting project.

    A wireless flash is good for taking a picture with the light source not being from the camera, or to get rid of shadows that are created from the camera’s own flash.
