Discussion Overview

The discussion revolves around the design of a shower timer circuit intended to reduce water waste during showers. Participants explore both mechanical and electronic solutions, discussing the functionality and components involved in such a system.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks a circuit diagram for a shower timer that can shut off or reduce water pressure after a set time.
  • Another participant suggests that the Shower Manager likely uses a simple timer/counter circuit powered by a 9V battery, potentially activating a solenoid to control water flow.
  • There is a proposal to consider a mechanical timer as a simpler alternative to an electronic solution.
  • A participant expresses a desire for an electronic solution that effectively stops water flow, questioning how a solenoid would achieve this.
  • Another participant explains that a mechanical timer could stop water flow at the end of its unwinding motion, while an electronic version could use a pushbutton and magnet mechanism to control a valve.
  • Links to resources about solenoids and their applications in valve control are provided for further exploration.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the best approach, as there are competing views on whether to pursue a mechanical or electronic solution for the shower timer.

Contextual Notes

Participants express varying levels of electronic knowledge, which may affect the depth of technical discussion. The feasibility of proposed solutions remains uncertain, as specific circuit diagrams are not provided.

Hi, I'm not sure if this is the right place to post this, so sorry in advance.

I'm doing a project on water. One of my ideas (I need to have a few initial ideas) is a shower timer, which stops people wasting water in the shower (like it will shut off/reduce pressure after a certain number of minutes). My model research idea is http://www.showermanager.com" , but I need a circuit to go along with in. I have scoured the internet but can't find any circuit diagrams to work with this! I'm not trying to build my own one, I just need a picture of a circuit diagram to go as part of my research. Any tips?

- Thanks.

Welcome to the PF!

It says that the Shower Manager is powered by a 9V battery, so it's probably just a simple timer/counter circuit, and it must fire a solenoid to shut down the water flow. It seems simpler to just use a mechanical timer instead (wind-up egg timer type) -- could you propose that instead, or does it need to be electrical in nature?

No it can be mechanical or electronic :)
The wind-up egg timer is easier, but I want something that will stop the water flow.
How would solenoid stop the water flow? (sorry I have very limited electronic knowledge).

Thanks for the reply.

The wind up mechanical timer would stop the flow at the end of its unwinding motion.

One way an electronic one can work is for there to be a pushbutton that pushes the valve open and there is a magnet that sticks to a piece of metal that holds the valve open. When it's time to close the valve, the circuit puts a brief, medium-sized current pulse through a coil around the metal, to oppose the magnet and force the magnet to let go. I'll see if I can find an example link...
