Hi,
Has anyone any ides on a circuit to make a random on / off switch.
The switch would need to switch up to 300ma.
With a random switch on time from 1 to 10 minutes and stay on for from 1 to 10 seconds.
Any ideas would be very helpful, thanks.

I doubt you'll find a circuit that will do almost exactly what you want. Everything is computerised these days compared to a few decades ago. You should learn how to make use of microcontrollers. I never had help from anyone, I taught myself. You can get premade microcontroller boards from the SparkFun website. They sell nice stuff there. Just get one of them boards and hook up whatever devices you want to it. You program the microcontroller in whatever language and mission complete! You'll be proud of yourself. I kick arse in microcontroller class. |

Hi Wasssup,
Thanks for the advice.
You are quite correct in that I am not up to speed on micro controllers or programming in C unfortunately.8-((
I think that I had better stick to a standard electronic circuit?
I have googled extensively but can't as yet find a circuit, been close with dice circuits but not the whole thing as yet.

Aaaah yeah! Just use a micro controller. If you program in C there should be a function like rand() that will generate a random number for you so that you can randomly get 1 to 10 as a delay. You probably wouldn't have asked this question if you knew about micro controllers. Anyway that's how I would do it. |
