Built using...
Early version of SenseCam
... Analog devices accelerometer
... A PIC microcontroller
... A digital camera (could only take 64 images)
... Hand soldered in Veroboard
... Programmed in PIC assembler (in 4k of memory)
First picture taken using SenseCam
King's College, Cambridge
And was further enhanced...
...changed the camera to a fish eye lens with very wide angle (104 degrees)
...light and color sensor to trigger an image (i.e. door frame detector)

...temperature and passive infrared detector (when a person is in front)
other people who contributed in sensecam project
- Andrew Blake (suggested to add camera)
- James Srinivasen (did the memory card software and other clever bits)
- Trevor Taylor (did a lot of the early pcbs and hardware)
