well... not explode.. but will it be damaged?
I need to hook up my sony viewfinder from my old camera to a smaller and more portable camera like a web cam, so Q1: is a web cam a good type of camera to do this with?
My plan is to first measure the voltage and current being supplied to the viewfinder from the original old sony camera, this is what i got:
-voltage being supplied from + wire of viewfinder to - wire = 5.10 V
-current (or power?) being supplied from + wire of viewfinder to - wire = 2.03 KΩ (not too sure about the units but 2.03 is definatly the # value obtained so Q2: is the 2.03 more likely in KΩ or Ω?
-voltage supplied from + wire of viewfinder to video wire = 2.07 V
-current (or power?) from + wire of viewfinder to video wire = 4.72 KΩ
with these values my plan is to connect the positive end of a standard wal mart 9 V battery (lets say 9V #1) to the positive end of the viewfinder, then connect the negative end of the view finder to a junction with a switch and then to the negative end of the 9 V #1. the video wire of the viewfinder will go to the video wire of the webcam. the positive end of the web cam will go to a seperate 9 V battery ( lets say 9V #2). and the negative end of the webcam will go to that same switch junction, then to the - side of 9V#2. Q3 : any problems with the setup ?
the most important question Q4: how do i find out what current the old sony camera was supplying to the view finer? and after i do is this the correct next step to:
calculate the resistor i need at the - end of the viewfinder with R= (9V- 5.1 V) / current supplied by old sony
if i find that resistor value and put it in the circuit will my viewfinder work?
Thanks a lot for you time!!
