Despite having some experience with Minecraft, the use of redstone is one thing that I never managed to get the hang of.
I have no issue creating simple works such as redstone doors and other manually powered mechanisms, but one trick has managed to elude me. This technique is a repeating redstone charge.
How would I create a repeating charge in a redstone circuit? Despite my tampering and experimentation with redstone repeaters and such, I've been unable to prepare my own answer.
Minecraftaddict's "Extreme Delay Redstone Timer" is the longest delay circuit I know of. (But I can see from the comments that you've already found it). However, directly using this circuit won't work with a light sensor output, since the output of a light sensor would be 10 minutes on and 10 minutes off.
The solution to this is to connect the output of your light sensor to a falling-edge and rising-edge monostable circuit that are OR'd together.
This is an image of a rising-edge trigger on the left, and a falling-edge trigger on the right. You would connect the A inputs together – to the output of your light trigger. When the A input is turned on, the Q output of the left circuit pulses. When the A output turns off, the Q output of the right circuit pulses. Because of this, you can connect the two Q output wires together (ORing them) to have an output that sends a signal whenever the light-sensor changes.
However, these circuits are designed to make a very short pulse. Because Minecraftaddict's delay circuit comes with a built-in pulse shortener, you will want to send a slightly longer signal to it. To do this, just add more repeaters to the edge triggers (add an extra repeater to when the current repeaters are). Leave the repeaters that should be on the first setting like that, but change the repeaters that should be on the second setting (according to the image) to the fourth setting.
It sounds like you want a lot of AND gates (sub-switches) with one common input (the master switch) in each gate.
Note: The piston is just an example of an output device.
Try constructing one AND gate for each sub-switch and connecting all the "A" inputs to a single lever and each "B" input to its own lever.
When connected properly, each AND gate will not be able to output power unless both the master switch is on and its corresponding sub-switch is on.
Be aware that redstone signals will only travel 15 blocks. A repeater can be used to extend this.

I believe you are asking how to make a redstone clock; a signal that pulses on and off.
There are many different ways to do this. For example,
Additionally, a more complex and less compact way of doing it is:
I hope this helped! If not please comment what is wrong! Oh yeah, welcome to the Arqade!
