look like I've Burned Up my Wireless 1.2 GHZ Camera.....

[lazy-b]

Have Installed a cheap Wireless Camera on Robinson R22 Coaxial Helicopter, works perfectly, have make a 2 flight......on a 3rd Flight, it stop working.

Have open up the Camera and find a Burned Up PCB Trace from the Power Supply input to Regulator.

The original power adaptor is 8 Volts, and I am assuming that it would be ok to use a 2 cell Lipoly Battery that about 8.4 (Fully Charge)

I am not sure the cause of its Burned Up PCB circuit board......plan to installed a single Silicon Diode (1N4001), this will drop the voltage by 0.7 Volts or can use 2 Schotty Diode in series (2 x 0.2 =.4 Volts Drop)

here is the video of Internal Camera, you can see a Burned Trace near that Regulator :

Have you encounter this problem.

Inside the original power cord near the end away from the camera is a 5 volt regulator. It is actually embedded in the plastic barrel at the end of the cord.

If you remove the original power cord you will need to regulate the power to 5 volts yourself. This can be done with a simple LM7805 linear regulator.

I don't know the specs on the original voltage regulator, but perhaps you provided more voltage than it could regulate down. If this is the case, you simple replace the power and ground lines to the camera and make sure they are regulated to 5 volts.

If something behind that is broken, its probably the camera, and now you have a nifty little miniature transmitter. Its the part with the tape around it in that video. Don't toss it, it might come in handy. You can attach the input wires to any compatible video source and transmit it just like the original device did.

Also FYI, I've given my similar camera up to 9.6 Volts with no problem at all. I can't imagine that 8.4 would be too much for that regulator to handle.

Plug it into a power source and check the voltage output at the camera board.

BushmanLA, Thanks for the Info........Yes, will try to reconnect that Burned circuit trace and hope it still work......better installed an Ammeter to measure current flow.
