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.

  2. Hi! I'm in a similar quest and I can't figure out why I can't turn my viefinder on (I wonder if it is broken, because the led that indicates it's on, brights) Do you have any idea on whay amp does the viewfinder runs? Could it be that my 1A charger burned it out?

    thanks!
