[net.graphics] Circuit to control camera...

jpj@mss.UUCP (06/23/84)

Greetings!  I am looking to control a Super 8mm movie camera by connecting
it to either a Centronics parallel port or (less desirably) an RS-232 port.
The intent is to be able to photograph graphic images automagically w/out 
having to hang around while they are being computed.

Surely this is a solved problem - could anyone share a solution with me?
My camera simply needs a closed switch contact so it sounds to me like I
want to drive a small relay - I'm just not sure how to do that.

Thanks in advance...

One of the neatest ideas I have seen to control a camera used a terminal's
internal "bell". You can either acoustically couple to the bell (using
a sound activated switch) or you can build a little circuit which detects
when the bell is being stimulated. The latter is probably a better idea
if someone has to work while you are taking pictures.

The result? For a couple hours of work you can drive your camera!
You might even be able to find an accessory for your camera which
is acoustically triggered.
