Hello let me start straight away by saying I know very little about electronics as I’m sure you will notice. I have been looking through your FAQ and at some of the site linked. I am trying to learn.
Anyway I started this whole learning electronics because I want to modify this timer I have (or rebuild from scratch if there are a lot of changes).
**broken link removed**
Anyway this allows me to pulse for up to 5 seconds and then pause for up to 60 seconds then repeat. Now I need to improve these lengths of time and as far as I understand using higher resistance potentiometers (I hope that’s spelt right) would do this.
So first of all is that correct?
Then secondly I want to up the times to 10 mins pulse and 7 hours pause which is a huge leap, and I'm totally guessing here, but that may be too much of a stretch for just changing the pots.
So is there anything else I should change on this to achieve what I'm after?
Here is the build guide I hope it has all the information that you need to help me.
Thank you very much for helping and if there is anything else you need to know I do have the timer with me so if the information is on a component I can tell you it.
Yes its possible do that, give us some details of what you want to switch.
ie: Voltage/Current AC/DC etc and what will be control voltage that operates the switch.
The switch will be operated by a 12V battery and it will be controlling the power to a water pump powered from the same battery.
The battery is a sealed lead acid 12v 7.2A battery.
Although the battery was based on the fact that the current switch needs 12V power it would be better for me to use a 6V 12A battery unless that causes many problems.
I came across this and it seems like it could do what I need but it is still a little out of my knowledge so could I just ask if this could do what I need and then I will spend a little more time trying to figure it out.
