Awesome Cat Cam
Posted on June 3, 2007 Comments (24)
CatCam by Juergen Perthold – this great project involved taking a digital camera and some additional equipment to create a camera that his cat wore around his neck which took pictures every 3 minutes. The pictures are great. The cat got photos of several other cats and seemed to like cars.
The VistaQuest made it very easy for me, because it is able to supply my circuit also if switched off. This is because of an internal DC/DC converter which boosts the voltage from the 1.5V battery to 3.3V. The DC/DC converter is always working because of the internal SRAM which holds the pictures. I just had to hook the microcontroller to the internal camera supply.
Well, I thought the hardest part is done by developing the software and soldering the controller board. But it is more the housing to protect the camera. You can not imagine what kind of requirements have to be fulfilled if you want to equip your cat with a camera. I built a small housing out of plastic plates and put it on the collar of the cat for evaluation purpose. This housing was last seen as the cat walked out of the door… Probably the wires I used for attaching were not strong enough. Or someone released the cat from the interesting looking piece.
For the second try I used the plastic package of a child toy (Kinderueberraschung), put a stone in it for loading it with some weight and attached it again to the cat collar. This time the part returned – dirty and scratched outside, water inside. What the hell is the cat doing !? This raised the requirements for the camera protective housing a lot
Big moment no. 1: attach the collar with the camera to the cat. The reaction was not very happy but finally accepted. Reality check passed 🙂
This is my favorite home engineering project. The concept is great. The explanation of the technology is great. The adjustment to real life situations is great. The end result (the photos) is great. This wins the non-existent Curious Cat Cool Contraption award. If someone doesn’t start selling prefabricated cat cameras I will be very surprised (if I was more enterprising I would do it myself). Maybe J. Perthold will, in any event he should inspire many to try making their own.
Update: site moved to a new host (after exceeding bandwidth limitation) and “CatCam fan pages and CatCam orders soon. I will also move the remaining parts of my WebWorld here.”
Update 2: order yours now.
