Eye-Fi and CHDK

with 3 comments

So we’ve got these really cool SD cards made by a company called eye-fi. The eye-fi automatically upload pictures to Flickr via wifi.

I’ve also been playing with a CHDK, a hacked version of Canon’s firmware for their point and shoot cameras. CHDK has worked beautifully, allowing me to take pictures in intervals and turn the camera off when it’s not needed (excellent for long deployment on a bridge).

I have, however, had one issue. To get the camera to boot CHDK, the SD card has to be placed in the “lock” position by flipping a switch on the of the card. However, the eye-fi has no such lock. So I’ve had to be a bit creative.

With some help, I cut a slot in the side of the card with a dremel, permanently locking it. No damage to the card was done; it’s still able to save images, etc.

A little piece of tape, placed over the new slot, will unlock the card.
