no name maker, but like this one
I cannot get the 2.4GHz link working, works wired in , clipped together. Anyone know what the secret is ?
The camera is outputting syncs only , rather than CVBS is the main problem, anyone know if there is a secret way in ? I suspect as supposed to be waterproof , then a matter of hacking in. It would be much more useful with a clipped on close-up lens, for reading script, surprisingly not supplied
problem,
Convinced myself hacking-in only. I hacked in along the mould line and accessed the inside without further damage. 22 way bridge between CCD plus 2x LED and rest of pcb, maybe fudgeable for miniture 7x7x10 lens and ccd . Whole ,with current pcb, could be easily cut down to 12x 7mm access port instead of 16mm original. Anyone knows of a simple "elephant trunk" mechanical manipulator mechanism? very stiff and unweildy spiral steel trunking umbilical as is.
uses wbcam type lens and CCD and Vimicro 44 pin VC0703NLEB cant get any closer than
vimicro is 48 pin , 15 thou/mil spacing
From this odd named file
That PDF is for a USB camera which would need VID and PID info from somewhere, hence the EEPROM. Your one's VIMICRO VC0703 chip is configurable for a lot more than just PAL/NTSC. I would expect the OSD feature alone to need an EEPROM to store the text and the rest of the config might as well be kept in the same chip.

there is only 4 wires between this camera pcb , down the 1m long spiral trunking to the monitor etc, 0,3.3V, illumination LED supply (variable), and CVBS signal out.
Repaired another of thse endoscope things, just mechanical damage to the metal barrel surrounded "S video" connectors used as small polarised 4 way connections. Sticking a 20D/ 50 mm focal length lens over the lens cover means you can focus down to a conventional 16 pin DIL package to read script. Image is then linear x2 so fills the height of the LCD screen.
If you were to cut away the waterproof lens cover and picked at the weak glue around the LEDs and lens carrier you could unscrew it , web cam fashion, to focus closer. Anyway given up on this one , come to conclusion half the vimicro is kaput. Annoyingly about 40 MHz clock and 9 output lines from the CCD work with plenty of signal variation to content of view variation. But CVBS output is corrupt , absolutely no image content. There are 3 sync pulses and 2 colour bursts per line interval. Tried removing EEPROM as no clock burst , just apparently matching L to H with 2 or 3 negative pulses only, then staying high, on (presumably) SDA and SCK pins. Removed EEPROM and same signal on vimicro pins , but then no o/p signal at all. Replaced with an as found
24C04 and same nothing out. Probably too much of a workup to descramble those 9 lines to give even just a monochrome imageElectronDepot website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
