Create a Reaction Test Circuit with LED and Electric Shock Feature

Click For Summary

Discussion Overview

The discussion revolves around the design of a reaction test circuit that incorporates an LED and an electric shock feature for players. Participants explore the technical aspects of the circuit, including the timing mechanism for the LED, the relay system for activating the shock, and the specifications for the electric shock itself.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant outlines a plan for a reaction test circuit where an LED lights up after a random delay, and the slowest player receives an electric shock.
  • The same participant seeks advice on how to disable the slowest player's switch to prevent them from being shocked while ensuring the fastest player is affected.
  • There is a query about the appropriate current and voltage for the electric shock, with a mention that typical devices use 9V cells, while an op-amp could increase this to 13V-14V, which may not be sufficient.
  • Another participant strongly advises against designing a circuit that delivers electric shocks, suggesting instead to use a reward system for the fastest player.
  • A later reply humorously suggests that a more complex circuit could potentially dispense chocolate as a reward, countering the initial suggestion of using shocks.
  • One participant expresses a nostalgic interest in building such circuits but clarifies that they do not support the idea of incorporating electric shocks.

Areas of Agreement / Disagreement

Participants generally disagree on the appropriateness of using electric shocks as a punishment in the game, with some advocating for alternative reward systems. The discussion remains unresolved regarding the technical feasibility of the proposed circuit design.

Contextual Notes

The discussion includes ethical considerations about using electric shocks, which may limit the scope of technical advice provided. Additionally, there are unresolved questions about the specific electrical requirements for the shock feature.

I am trying to make a reaction test circuit where a LED comes on at after a random amount of time and the slowest player gets and electric shock.

The switches they press turn on a relay to another circuit connected to the device which shocks them. I need to find a way to stop the slowest players switch working so the fastest player doesn’t get shocked.

I also need to know what current and voltage the electric shock should be. Some one told me that it ises a small current and a large voltage. The ones you can but in shops are mostly use 9V cells, but using a op amp would make it 13V-14V which probably wouldn't be high enough.

If anyone has any suggestions to either problems it would be very useful.

It is not a good idea to design something that will electrically shock an animal, person etc.. I suggest instead of using a pain to punish the slowest player, how about using a reward as incentive, such as piece of chocolate to the fastest player :-p
 
Well it was a reason to do something with amplifiers but I have solved the problems now. Chocolate can’t be given out by a circuit:smile:
 
Sounds like something I would have wanted to try in my younger days. (The building part, not the playing)

Sure it can. The circuit just needs to be more complex. :smile:

Sigh. You were doing okay until the "help me figure out how to shock people" part. That's not something you will get help with here on the PF.

Thread locked.
