Hello Techies
Thanks for your help in advance.
I am a electronics tinckerer and a diehard fisherman, I was looking to build my own underwater camera for ice fishing this year because all the retail ones are too expensive and don't have the photo quality I could build.
So heres the setup
The casing will be made out of plexiglass tube welded with weld-on 3 to a piece of 3/16 plexi on either end and a micro HD CCTV camera encased in there along with 6-8 leds and a tether to topside and the power and screen. Now I am looking to power this with a standard Vexilar 12v 7Ah battery. This is the spec sheet that came with the camera. One thing I don't understand here is it says 3.3 - 6v but came with a 12v wall wort power suppy, now I realize this has to do with unregulated and regulated whereas I will be hooking it stait to a 12v battery which would be not unlike hooking it to a regulated power supply at 12v not falling off during draw.
Now my question how do I run this camera without damaging it with a 12v deep cell battery? What resistors and such would I need to put in series with the supply line to make it not fry the camera? How long would the battery last?
Also I have a 7" Color TFT LCD Car Rearview Monitor for DVD Camera VCR that I bought off ebay here and it says it consumes around 8W how long would the battery last powering both the screen and the camera?
