cam_20181029_175031.jpg - Sony SNC-RS84P all the bottom networking and powersupply stuff removed
cam_20181029_175036.jpg - the camera unit is full resolution PAL 576i S-video with seperate Y-C
This video format I simply "convert" to composite, with 470pF from C-Y and out put from Y, looks great

cam_20181029_191521.jpg - stepper motor controller and switchmode supply for cam board
I was affraight I had to invent the wheel and make my own stepper controller, but lucky me, it turned out
this pcb also use a normal sony visca protocol to handle cam control, offcourse they do, this way other cams can use this pcb alone
At power up it even say a short number on the serial, so i could measure the baud to 38400, the first address is 81
and what luck it responded all perfect. So i saved alot of time here.

cam_20181225_205925sensors.jpg - to be able to "see" in all 360 deg, no matter where is cam is pointing
I add 8 sonic distance sensors under the cam mounting, this way there should be no surprices from sides og behind.
cam_fusion360-design-sonic-holder.jpg - it is easy and fast to design simple objects in Fusion 360 and 3D print them
cam-magnet_20200310_183137.jpg - camera zero point magnet, 4 x 1 mm metal holds the magnet
cam-magnet-offset-thingy_20200312_200026.jpg - here is a little 3D printed thing to offset the magnet
this way the camera can look a little bit down as needed.
