Box / case
I’ve built the camera to be modular which helps when tinkering about with it but does take up a lot of space, hence the rather cramped appearance.

Examples
Filmed through glass and saved as an mp4
Filmed outside running on batteries. Video has been cut down in length using windows movie maker so is saved as a wmv
Now using adobe elements and with the interesting vids cut together
Improvements
Now that the weather has given me the chance to run the project outside, there are a couple of areas that I’m not happy with:
- reflection – there looks to be a noticeable reflection from the light on the lens (not helped by the badger nosing it!. I need to find some way of keeping it waterproof whilst stopping the reflection – also might try and find a way to stop the IR filter cutting off the corners of the image.
- Brightness of image – the image is too dark and noticeably darker than the previous version. I think that this is partly due to the camera being set as “auto” (hence it brightening up after the bager nosed it) and partly due to the lamp
- Lamp connection – The hardware weak point is the connection to the lamp. At every opportunity the wires fall off to such an extent that the solder pads on the lamp have fallen apart.
