View Full Version : camera veiwfinder modified to work with wireless camera?

I salvaged a viewfinder from an old Sony camcorder, and I was wondering if there was a way to get it to take the video from my wireless cameras receiver. I want to make something similar to eyetop glasses for framing AP shots.

I have taken a couple pics of what I have.

the first is of the bottom and is the most useful, I think. The other is of the top. On the bottom, the ribbon cable from the big camera board goes into the board which I think controls the screen and then another cable goes from the board to the screen. The cable kind of splits into a sub cable before it goes into the board, and the part that splits off goes into another board, which just controls the backlight LED. I'm not sure why there's six wires going to it, but I think the bigger ones are the power wires. The part that goes into the main board also has two wires that are a lot bigger than the others and a third that is only slightly bigger than the rest.

I think the big ones are the power and the slightly bigger one might be the video signal. This is where I could really use some input:D

My plan is to use my multimeter to check the thick wires and see which is - and which is + and check the voltage. Then hook up a battery of appropriate voltage and then hook up the outer part of the video cable to the - and the center part of the video cable to the medium sized wire and see if it works, or lets out magic smoke.

thanks

I checked the voltage, and am now totally lost.

the middle of the two largest wires was negative

the one one the edge was 2.86v and so did a lot of the others

the medium sized one was 13v

the cameras batter is a 2 cell li-ion, so the camera has to up the voltage in there somewhere. My only guess is that the screen needs it to run.

I have no idea where to put the video signal, or if I even can.

Get a pinout on the chip, odds are though it will be some format where you'll need to program a AVR or something fast to decode and recode the data.

how do I get a pinout?

I don't know how to program AVRs, so my only hope is if its in a usable format:(
