Olympus Mju 300 Digital Cameras are 3.2MP cameras that are suprisingly good cameras to hack up, they have 3x optical zooms, Li-ion batteries, accept XD cards (slightly annoying) and have IR remotes. But the best thing is that the on/off switch (which is activated by sliding the cover back) breaks very easily, these models end up on ebay - however this is easily fixed.

• Open the camera up and glue the on/off switch continuously on so that you just insert the battery to turn the camera on.
• Instead of directly interfacing with the shutter switch which often bricks the camera we are going to hack up the IR remote instead.

• Step 1 - remove the front cover (force should take it off)

• Step 2 - Remove screw on the top left side

• Step 3 - Remove screw on the bottom

• Step 4 - Remove screw hidden beneath the battery cover, its the small one in the bottom right - I didn't take this screw completely out so that I didn't lose it.

• Step 5 -

• Step 6 - Remove 2 screws around the LCD and the 2 screws inside the side cover

• Everything laid out

• Step 7 - Careful pull everything apart, avoid touching the capacitor (its quite well hidden in this model), the on/off switch is just above the IR receiver, a blob of super glue can keep this stuck down and always on.

• Step 8 - This is the IR transmitter, I haven't yet adapted it but the plan is to bypass the on switch with a wire soldered between so that the transmitter is always on and remove the 3v cell instead replace this with power supplied by a GPIO. Just turn the GPIO on, it powers the transmitter which triggers the camera to take the picture.
