Hacking an Olympus Mju 300 Camera
WARNING - Digital Cameras have large capacitors which often are charged (and remain charged for long periods of time) - they really hurt if you discharge them through yourself and will destroy chips!
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.
Opening the Camera
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.
