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!

Introduction

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.

The Plan

  • Open the camera up and glue the on/off switch continuously on so that you just insert the battery to turn the camera on.
  • Either
    • Instead of directly interfacing with the shutter switch which often bricks the camera we are going to hack up the IR remote instead. I used this when I adapted the camera for Peg V and taped it to the front of the camera infront of the port
  • Or
    • Bypass the shutter switch This is the most generic way, it requires a bit more work and therefore more risk of bricking the camera

Opening the Camera

  • 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 - Remove 2 screws around the LCD

  • Step 6 - Remove 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.
