If you look closely at the camera, so that drops to about 2/3 of the housing volume is occupied by the battery compartment. Only the front, round part houses the electronics. Since I want to use the camera in a confined environment, I've broken down the same time, what is going amazingly simple. The round part of colorful ring is clipped and can be easily removed with your thumbnail. If one has the hemispherical cover are removed even the two boards free, the complete electronics.
The top board includes among other things the camera the bottom including the wireless chip. Both are connected to a Board to Board Connector and obtain a distance of about 5 mm to each other. This distance have the boards but also urgently needed because the bottom is hot at room temperature without housing about 65 ° C or 75 ° C. These temperatures I measured at two unterschedlichen cameras. This suggests two things: 1. The life will not be too high because hot components age much faster than cool. And 2. the battery should not hold too long. The module takes approximately 1 W to. Judging from about 950 mAh a CR2 from safe arise no more than 2 to 2.5 hours at impeccable, not superimposed brand batteries.
The upper board can simply disconnect. But Beware! The Board is determined via two cables on the battery. The bottom board is clipped only into plastic. If you are just curious and want to then build the whole thing back together one must be careful here not to lose the small slide for the switch, the loose is below the lower board.
For better cooling I have filed the smaller heatsink, a set which itself was intended for a Raspberry Pi to 2 mm. He just does not fit between the boards but beware, the heat sink in the middle of the chip place otherwise there shorts. This brings about 10 ° C probably right on the chip a little less.
Now I'll instruct my 3D printer with a compact housing. :)
All in all, a very compact wireless camera that delivers an acceptable VGA image. With a little tinkering you get an even more compact camera, the MA can then be built into a small robot or similar.
Oh, who takes his camera so apart needs are guaranteed not to worry :) The then there no longer!
