    I wasnt expecting quite a comeback ...lol

    However, there is a minor error in your calculation. Conductivity is a volume measurement, not a distance measurement. You have to calculate the effective area of the connection (in all directions) and divide it by the distance. It makes conductivity go up real fast.

    I once did a little experiment at work. We were working on a high powered alternator syetem for an MRAP vehicle.

    There is a requirement that the truck has to go thru water of a certain depth, and the water might be salt water.

    I was curious what would happen if I took no precautions.

    I bought a 100 gallon rubber animal stock tank at tractor supply, and put part of my system in it (minus the alternator). The alternator was outside, running off a big electric motor. I expected the current to all be in the milliamp range so I ran some #22 wire from the alternator to the equipment in the tank and filled the tank with fresh water.

    Current was indeed in the milliamp range.

    The I dumped a cup of rock salt into the 75 gallons or so of water in the tank.

    Within a few seconds, I watched the wire get so hot that the part of the plastic stock tank that it was resting on started to melt.

    It was "lots of amps" at only 28 volts.

    Yeah I overlooked area, you get more current with the larger area of those pins.

    I know how salt can change water to a conductor too. A work we have DI water measuring 10-12 M ohms and if you touch the water with your fingers it changes to K ohms almost instantly.

    I am planning on putting that USB port on my ram tough hub when I get a few days off work to install it. That will at least isolate the motherboard.

    The next project is pimpage up front. I installed a forward facing camera and an LED Scanner bar in the "SS Mailslot". The mailslot is a fake hood scoop that the gen 5 SS Camaro's have on the bumper, so I wanted to go KITT with it. What I did not like about the scanner's available was the white LED's showing, rather I like it to look all black unless lit up.

    Here is the standard LED Mailslot Scanner installed. The LED's are visible as white squares across the scanner:


    I painted mine with a very thin layer of black spray so the white LED's would not show as much as on the standard scanner:


    Next I put clear shrink tube over it to protect the thin paint from routine car wash scratches and the elements:


    Then I tested it to see that even though painted, the paint layer was thin enough to let light through, PASS!


    I fashoned a camera bracket out of aluminum and mounted the forward facing camera inset as far back as possible on the grill, and the mail slot camera in place. The camera has a swivel mount that allows me to aim it as desired, then lock it in place with a set screw. I aimed it straight ahead so I can record videos with that high speed effect, camera being as low as it is. It's been raining, and this is my daily driver so by Saturday morning, my car is filthy!




    Back in the garage, I built a box to interface the camera, and scanner, with my carpc. I have a RAM USB Tough-Hub, and Easy-Cap Video Capture board, and a 0/16/16 Phidget I/O card inside a laser cut ABS box. The Phidget controls camera power and power to the LED scanner. I have a 5A breaker, and only intend to power LED or low current devices from the Phidget, so I alloted 2A to the Phidget and 3A to the HUB. I plan on installing it this morning since it's not raining.

    Shame the LEDs aren't red and go back and forth.

    They do go back and forth, and have something like 20 modes, but after seeing the red LED's on a white car, I decided on white LED's. I have a multi color scanner that I tried out first, but I did not like the White that it produced. It only makes 8 colors, and I did not prefer any of those colors so I bought the all white one.

    The camera was going to be my next step in my system. What camera are you using? I opted to go with a small webcam and mount it right infront of the rearview mirror for a couple reasons.
    1/ where you are mounting yours won't it be suseptable to rain, even worse dirt and grime that will basically make the capture useless or be in the need of constant cleaning off?
    2/ won't the heat from the engine be a problem...especially in the summer?
    3/ I wanted a good camera but. Couldn't find a quality camera that was small, and then a small converter. Reading up on your capture converter reviews it has very poor results overall, what has your experience been?
    4/ I don't know if this is your route, but I want data captured and recorded with mine, will you be able to do that with a camera that's not a webcam?

    I got this camera, mainly to aim down low to see the curb so I don't scrape the splitter on my ground effects kit:
    Car CCD Camera Front View Non-mirror 360 Angle Rotation Waterproof Night Vision

    Image Device Sharp CCD sensor
    View angle 120 degree
    Type Composite Video
    Image Non-mirror image for front/side
    TV System PAL/NTSC
    Waterproof Rate Yes. Ip66
    Effective Pixels PAL 720*576 pixels,NTSC 720*480 pixels
    Resolution 420 Lines
    Minimum Illumination 1.0Lux / F1.2
    Pinhole Lens f=1.8mm / F = 2.0
    Vertical Sync. 60Hz
    Video Output 1.0vp-p, 75Ohm
    Power Supply DC12V
    Current Consumption ≤120mA
    Operating Temperature -20C~70C , RH95% MAX
    Storage Temperature -40C~85C, RH95% MAX
    Construction Material Aluminium alloy shell
    Shock-proof Yes
    Dust-Proof Yes
    Diameter 18.5mm

    Heat? Speced at 70C. Should not be a problem because it is mounted 14" off the ground on my grill, about 8" in front of the radiator. The radiator is driven by 2 electric fans on the backside, so there will probably not be too much heat for this camera. Not only that, but the camera is mounted inside a folded aluminum sheet holder I made for it, so the aluminum should shield even more heat.

    I have an old EZ-Cap SM USB 007 cpature device that came with an install disc and windows 7x64 drivers. It works just fine with their capture software, with a surprisingly decent picture, much better than my OEM backup camera from Chevrolet displayed on the same screen. There is one problem however, and that is that the device does not work in Driveline. When I use Driveline to view the camera, my USB Audio DAC starts to skip and the video does not come through. So I have to use it from the Driveline Shortcuts page instead of the camera page. I am looking for a different device to try now.

    With the current mode, I can record video, at the same time as I display on screen.

    I had looked for USB webcams, but could not find any exterior rated devices that were not horribly oversized, where this cam is a tiny 3/4" ball with a pretty decent picture for 480p resolution.

    I wish I had real fab experience, but truth be told I have never layed any fiberglass before. I really want to learn to fab some speaker kick panels like were popular 20 years ago, or even today's column tweets.

    I do however have a laser cutter for cutting Acrylic and ABS panels, so I can make bezels, and other types of mounting plates or boxes. I can also do text on things, like making thin (.003" peel and stick) vinyl labels for stuff... Power, Reset, etc. If you need something along those lines let me know.
