Apologies if this is not the right kind of forum for this, but it came up in my search and appears to be the kind if place I'm looking for.
I am a complete amateur when it comes to wiring and circuit boards; not even an amateur, a complete noob, I know next to nothing other than LED's require resistors to prevent them from burning out. What kind of resistors? I don't know. So please keep that in mind and bear with me.
That said, I am hoping someone here would be willing to help me come up with a simple diagram for an LED bar graph circuit made out of parts I can find at Radio Shack, online, or other small electronics stores that I can put together myself pretty easily (So long as I can solder and follow the diagram). The LED bar graph would simply bounce up and down, similar to what you would see on a stereos sound level graph, or what is seen in the video below, but the pattern does not actually have to represent a read out.

The LED bar graph in the video was created to display the RPM of his hard drive, and from what I can tell requires special computer peripherals to program the circuit, which I'd rather not have to purchase.
There is another circuit I'm interested in too, preferably running from the same on/off switch and power source as the LED bar graph, but it doesn't have to, and it is much more simpler. It's just a couple of static LED's, a couple of blinking ones (no pattern), and a strobe LED that turns on at the press of a momentary push button.
Again, I apologize if I have come to the wrong place, and if what I am asking for is a bit more complicated than I think it is, please let me know. If anyone is curious what this is for, it's lights to go inside of a movie prop replica.
Any help is appreciated, thank you! And if you need any more info please let me know.
