Viewfinder CRT scope

The viewfinder-tube is from an old Video8 camera. It's a tiny TV monitor. I use it like a oscilloscope.
Hier seht ihr eine kleine braunsche Röhre aus einem Sucher einer alten Video8 Kamera.

very cute!

how did you find the pin volts?
-
I have tried to get video from 2 different viewfinders, fried them both. Its a tricky thing to get working (IMHO).
-
The video was cool until you put that shitty music.

Ich finde Deine hier vorgestellte Idee super schön.
Ich kann mir nur so gar keine Vorstellung von diesen orig. Kameras machen, waren das "jedermann" Kameras? In welcher Zeit wurden die gebaut, und war der "Sucher " so etwas wie ein Kontrollmonitor etwa vergleichbar dem Display der heutigen digital Kameras? Konnte man die eigene Aufnahme auf diesem "Sucher " auch wiedergeben? Video V8 war das MAZ oder FAZ?

hey i have one of those but i dont know how to use it. i have a 4 wire ribbon strip coming out of the curcuitboard, i would guess that these are 2 for power, and 2 for control. if you could help with this it would be great(not to have to spend as much on an oscilloscope that is)

Hey ben,
two wires are for the power, of course. One of the other is for the video signal. The best way to find out which one are for power is to measure the voltage while the camera is on. Power should be about 5V. The video signal is difficult to find without oscilloscope. If you use a voltmeter it should be 1 to 2 V. Ground is mostly easy to find by a close look at the view finder board.
Be carefull with touching the board while it is powered. There is a high voltage part (500V)!

do you have the schematic? anybody sell any kits? I have that tube.

Sorry for the late answer. I don't have any Schematic, but if you're interessted in CRT techniques, then I can suggest you the Philips EE2007 experimental kit. There are schematics for oscilloscope tubes.
There are no kits, but you could buy an old Hi8 Videocamera and remove the hole viewfinder. This is all what you need.

Das ist eine gute Frage, ich weiß es nicht, da ich die Elektronik vom Sucher der Kamera verwendet habe.
meikewaldmann 3 years ago
Yes, I've bought three old cameras for one euro from Ebay.
