mini crt monitor hack




Last week I found an old broken Panasonic VHS-camcorder on the street near the recycle bins.
The camcorder was not powering up ...but... this old camcorders have very small crt b/w viewfinders. The interesting thing is that most of them have a native composite input.



Attention:
It is not recommended running them without a case as they can give you a nasty shock!

With a simple hack you can use the viewfinder as a standalone battery powered mini monitor.
You need to identify the ground, power and the signal pins on the PCB of the viewfinder. Then connect the pins with a RCA connector and a power source like this:

As power source I've used a 6v battery pack.
