Dealzmodo Hack: Juice Up Your Canon Digital Camera With CHDKJohn Herrman10/30/08 4:00pmFiled to: Dealzmodo hacksDealzmodo hackDealzmodoDIYHacksCanonCHDKCanon firmwareCanon upgradePowershotelfIxisCanon softwareCanon chdkDigitalCamerasCamera28EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkDigital cameras are generally closed platforms, built and programmed under the assumption that they would never be modified. To get more features, you pay more for different firmware, even though the guts are mostly the same. Canon didn't batten down their hatches quite enough. The result is CHDK, a full-featured OS substitute that runs from your memory card and unlocks the tremendous unrecognized potential of most Canon A-series and SD Elphs plus several others—for free. CHDK isn't hacked firmware, and it doesn't require any risky flashing or OS replacement. It's non-destructive software that runs directly from a memory card, so it won't affect your warranty. But you'll still get an experience akin to an entirely new operating system. What new features will your tired old Canon gain with CHDK?

You'll need: AdvertisementA Canon digital camera from this list, with compatible firmwareA card reader for whatever format you use (probably SD)A build of CHDK for your camera from this page Once you've got all your stuff together, you're ready to load CHDK up: 1. Copy the PS.fir and Diskboot.bin from your downloaded ZIP file to the root of your SD card (not in a folder) 2. Turn on your camera in "Play" Mode 3. Press "Menu", and select the menu item "Firm Update" and confirm For instructions for automatically booting into CHDK, check here. Again, since this is not an actual firmware upgrade, you can just pop out the SD card and batteries should anything go awry. When you put the batteries back in and restart your camera, you'll revert to where you started. Installing CHDK isn't quite like getting a new camera, but it's a sure value-add to your trusty old one. For more information, hit up CHDK.
