and

It needs to be able to start, run for a set time say 30 minutes and stop, 12v, HELP PLEASE, happy to return in wrong and buy the right thing, as there is NO wiring help we are stumped, AUTISM

Thank you

The simplest solution is probably a plug-in timer than has a settable countdown mode, such as this:

https://www.amazon.co.uk/Digital-Electric-Socket-Countdown-Appliances/dp/B08DR71WZX/ref=sr_1_8?crid=2FC6USLV4ALR2&keywords=timer+module+plug+in+countdown&qid=1656856480&sprefix=timer+module+plug+in+countdown%2Caps%2C59&sr=8-8

Just plug the motor power supply in through that?

How can that help when I said it has a 12v supply you can see the battery "AA" supply plugged in ?????

The first timer you list should do fine. It has the 12V input for the control circuit (blue connector) and output connector (green) to control one wire for power. All you may have to do is put an extra jumper from the blue + pin to one of the green connections. The other green will be the +12V out controlled by the timer.
This all assumes your 12V has enough capacity to run the timer and run the device all at the same time. AA batteries do not have all that much capacity...

Sagor 1 Thank you

I have autism, any assistance you could offer showing me in a drawing what you mean would be most appreciated

I did not know what the other box was, there is no identification.

For something motor-driven that runs for long periods, I expected a mains PSU with 12V out.

Something like this, which would likely work and save the cost of batteries?

Where can I see this?

Here is the battery supply

And how is that an AA battery?.

celestronuser · Jul 4, 2022

Are you serious, I assume you know NOTHING about electronics that is a laugh on an electrical forum LOL ROFL

celestronuser · Jul 4, 2022

I clearly stated

"It needs to be able to start, run for a set time say 30 minutes and stop, 12v" FOR those who don't know 8x1.5v is 12v

Easy Guys , Easy !

He's been upfront and mentioned his autism, but not the difficulties that presents and he's been here before asking help but gave up and ran off because of the endless criticism and teasing he got.

We both know that's an AA battery box .. .. . probably for 6 x AA batteries. If the motor is 12v it would run, albeit slower than expected ?

Come on, please be nice or if can't - shut up !

Oh my god thank you

It is hard to ask for help, and I always tell people I am an Autistic father with THREE autistic sons.

ANY help would be so much appreciated

Thank you

The timer you bought will work fine... Sagor is probably drawing a circuit up... All you need to do is separate
The positive coming from your battery box and route it through the relay connector... The other ( blue) connector is 12v ~ 0 volts... Personally I would unsolder the battery box and connect those wires to the blue connector, then run another pair back to the battery..

Bless you, I will try that after I have had a cup of tea and calmed down as my disabled son has today been a victim of disability abuse (reported) MANY thanks

celestronuser · Jul 4, 2022

I have taken a brake as I am getting so frustrated, autism

I thought I had done 100% what is shown all I get is a red light nothing turns on

Has to be me, thanks and sorry

Ian Rogers · Jul 4, 2022

Wiring in picture 1 is correct... Has the batteries run down... As the timer is 12v it my drop out at >10v.

celestronuser · Jul 4, 2022

Idiot

You know as soon as I had powered the computer off I KNEW I should have said I am trying it with a 12v 1000mA mains adapter

SORRY

celestronuser · Jul 4, 2022

Stephen also has this one but wiring that is mind blowing
