NC open with condensor microphone

[ArneF]

Hi all,

I am using an electronic timer when shooting (CED8000). This also has the possibility to record man vs man. For this I need a normally closed cable for each shooter. The cable should open for a very short time when a shot is "heard".

The manufacturer does not sell such cables, and has no tips on how to make them.

I hope someone here can show me how to make such cables.

t is for the CED8000 found here http://www.cedhk.com/show.php/Object518

have a nice day

What are you shooting? Is this for paint ball fights?

Why do you need to switch the cables? Do you have a circuit diagram of the present setup?

What are you timing?

Scenario is:

2 shoters with each 5 targets.
The timer records, among other things, the time for each shot and total time.

So I need 2 cables, each with a micophone at one end and a jack in the other end. The cables should be normaly closed and open for each shot. The opening of the closed cable will be recorded in the timer as a shot, and the time recorded.

(The competition is to shoot down the 5 targets fastest, and is done for all calibers, .22 - .38)

The shots come very fast and therefore the circuit must close again very fast after each shot. The normal time for shooting down the 5 targets is around 2-4 seconds.

Hope you have an idea :-)

Problem is solved.
Thanks anyway
