I have a ccd camera that I put a peltier element into, and there is noise from the power supply, even when it isn't plugged in. Just plugging the jack in gives noise, I tried the bypassing thing with a capacitor with no effect. Plugging the PSU in gives no change. I tried moving the power supply around and this makes no difference plugged in or not, any ideas? If the noise is from the power to to camera from the usb port, why would it only appear when i put the jack in? I really am confused with this.
The case is plastic, and i just noticed that when you even touch the 0v pin of the socket for the jack with a metal object, the noise comes back.
