work in progress (isn't everything?)

After sudo apt-get upgrade and using raspi-config enable the camera and reboot with camera connected to the black connector next to the network socket.(lift the sides to open)

The camera takes around 250mA and while in use the pi itself will be working hard to control and write data. This should be considered when chosing a power supply. an old Pi b, wifi dongle and a camera may well tip your avo over 1000mA.

Infra Red

I now have a a pi Noir cam, identical to the usual pi camera except it does not have the IR filter on the lens therefore it is able detect infra red at around 850Nm. This coupled with some small IR lights will allow me to use the camera in very dark environments. The lights in the picture above are IR but the cameraphone I used has picked up the infrared very well. The momentary aim is to monitor my garage door as someone has been attempting to steal my motorbike from within. I would also like to use the picam for some high framerate rideout movies by attaching the pi to the motorbike or my helmet.
