Thread: Displaying reverse camera on a carputer?

I got it hooked up this weekend just as eCar described - I unsoldered the switch off the board and ran a pair of wires out to a relay triggered by the backup lights - works great. The switch on the board is a double pole-double throw but you only need a single pole-single throw to trigger it. The Cheesebox needs a constant 12v to keep the vga passthrough active - I used the Opus +12v to supply it and the camera (a reverse camera off eBay), together they draw about 170 ma. There's about a 3 second delay when it shifts to the camera but the switch back to the vga is instantaneous.

So you connect the 12V to the Cheesebox? I got one of tehse, and the DC power supply it comes with specifies 9V input only.

Would it work to connect the + to my Opus's 12V and the - to my ATX 3.3V, or would that make something explode?

Also, in the diagram there's the SPDT at the bottom, then a blue box, then two squiggly fuses. What's the blue box between the fuses and the SPDT?

That's a SPDT relay at the bottom. You could also use a SPST-NO (normally open) relay, as it is the same thing without the unused #87a pin (that provides a NC output). I showed the SPDT because SPST-NO is not too common.

The other blue box (at the top) is a SPDT 3-position ON/OFF/ON switch (shown in the OFF pos). You use it to select the automatic mode (connected to the reverse lights), camera mode (connected to +12V), or VGA mode (switch is off).

why don't you get a usb quickcam???

Aksor, if that was directed at me, I am looking for something that will be on as soon as I start the truck. The reverse camera makes the most sense when backing out of the driveway or a parking spot - I don't want to wait the time for the CPU to boot and everything to load - it would be simpler to just push the button to change sources. If I have to go with the cheese box I will, but I know it is probably possible to do something similar with the lilliput since it has VGA and RCA inputs, but don't have the skillz to do it

I was looking for the same. I dont found any post about it
but if anywone finds anyting so let me now maby Armen have a solution

I figure that it would need to provide a single momentary closed state when in reverse to get to analog, and then two momentary closed states when going out of reverse to return to VGA. It's be cool to see this work.

Hey guys i want to have a reverse cam and a cam for the front of the car. How would i go about connecting theese. The front cam can wait till my carpc is booted but i want to use the reverse cam asap so on something like the cheese box. I live in the UK so is their a cheesebox alternative to this ?
