We’ve seen a few builds using this firmware to take pictures of the sunrise every day and transmitting images over a radio link, but this build is far more interactive. The camera in question is a Canon IXUS70, although any camera supported by CHDK will work.
#CANON EOS 350D FIRMWARE HACK ANDROID#
They’ve made a Bluetooth controller for a cheap Canon camera, allowing pictures to be taken with an iPhone or Android device. Loading point and shoot digital cameras is old hat around here, but and are taking it to the next level. Posted in digital cameras hacks Tagged arduino, canon, digital photography, dslr, leica, logic probe Of course, if you don’t mind completely gutting the camera, you could always convert your old Leica into a point and shoot.
#CANON EOS 350D FIRMWARE HACK CODE#
What makes a beautiful piece of work even more beautiful? Sharing the source code and schematics. These quibbles aside, it’s a beautiful hack so far. Additionally, the Canon’s anti-IR filter didn’t fit, but he has a new one ordered. The shutter speed is limited by the latency in getting the signal from the Leica to the 350D back, so he’s stuck at shutter speeds longer than 1/8th of a second. There are still a few outstanding details. The Arduino listens for the Leica’s bulb-flash signal to tell when the camera fires, and then sends along the right codes to the EOS back. But it’s not even that simple.Īlong the way reverse-engineered the EOS 350D’s shutter and mirror box signals (using a Salae Logic probe), and then replicated these signals when the Leica shutter was tripped by wedging an Arduino MiniPro into an old Leica motor-winder case. Just a little bit of extremely precise hackery. It sounds simple, right? All you’d need to do is chop off the back from the EOS 350D, grind the digital sensor unit down to fit into exactly the right spot on the film plane, glue it onto an extra Leica M4 back door, and you’re set. So he Frankensteined them together and added a digital back to the Leica’s optical frontend. starts at 'firmware' offsetįirmware length (encrypted part).Wanted to use his vintage Leica M4 as a digital camera, and he had a Canon EOS 350D digital camera sitting around unused.
