Discussion Overview

The discussion revolves around the need for a normally closed cable with a microphone for use with an electronic timer (CED8000) in a shooting competition context. The focus is on creating a custom solution for recording shots based on audio input.

Discussion Character

  • Technical explanation, Experimental/applied

Main Points Raised

  • One participant describes the requirement for a normally closed cable that opens briefly when a shot is detected, to be used with the CED8000 timer.
  • Another participant inquires about the type of shooting involved and requests clarification on the need for switching cables, suggesting a circuit diagram might help.
  • A later post elaborates on the scenario involving two shooters and the timing of shots, emphasizing the need for rapid closure of the circuit after each shot.
  • The final post indicates that the original problem has been resolved, but does not provide details on the solution.

Areas of Agreement / Disagreement

The discussion does not reach a consensus on the technical solution, as the final resolution is stated without elaboration on the method used.

Contextual Notes

Details regarding the specific design or components of the proposed cable solution are not provided, leaving potential gaps in understanding the implementation.

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
Arne

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
