Hello I have built the 555 delay power off circuit by using these 2 guides:
I using a 10kohm potmeter + I was experimenting with 100 microfahrad - 1000 microfahrad caps. With the 10k + 100micro it switches off after 2 minutes something but not always in the same time and some time it stays on forever.
I have tried another new 555P ics in case it would fry or something but no luck. Can somebody see anything wrong with my circuit on the picture?
The red LED coming from the 2nd example (I think that circuit is bogous), even if I disconnect that part it does not make a difference.
