It can't give out pulses, can it? I'm not much of a electronics guy but according to my googleing and the schematics it's an inverter. I need an continious stream of pulses.
Could you please elaborate where to add the quartz/resonator to get a higher frequency.
I think 555 typically runs at 2.1MHz, usng 1k and 10k capacitor and a resistor I can get 900 hertz which is around 15 mouse clicks per second. I need ~4 times faster.
Well, am I using the wrong capacitors and resistors then? Or maybe my mentioned 900 hertz is wrong? Either case with that chip and those 2 parts I can only get 15 clicks per/s max.
Using 555 in astable mode:
10K Resistor
1K Resistor
4.7uF Capacitor

I assume R1 = 1K and R2 = 10K. That would indeed give 15 "clicks per/s", which is 15 hertz. "Hertz" means cycles per second, not per minute.
To make it go faster, you just need to use a smaller capacitor. The frequency of the output in Hz (or clicks per second) is inversely proportional to the value of the capacitor. e.g. If you go from 4.7uF to 0.47uF, the circuit will run 10 times faster.

Okay so this should work now?
Also, where should I add an LED that will also flash with that frequency when on/off is used.
Sorry, I draw both 1k, but bottom is 10 with 1/4w.
Edit: found this online editor called circutlab, I have no idea how to use the simulation.
So this is the same schematic I made before, except this time I added an LED to the output, so if push-down button(mouse button) is pressed down, the circut runs, outputting that frequency and flashing that LED at the same speed, correct?

That should work OK. However I'd connect the bottom of the LED to ground instead of to the output because it's probably flashing too fast for the eye to pick up, so it will look like a continuous glow anyway. If you can see the flicker, it will just be annoying/distracting, IMHO.
At least it let's you draw neat diagrams unlike some of the garbage that get's posted around here.

How to annoy everyone in 3 easy steps:
Draw a messy diagram with a crayon on a piece of scrap paper.
Take a blurry photo of it with your cellphone.
Upload it as a 2MB attachment.
No kidding! Some people actually do stuff like that.

BTW, I'm curious: What do you plan to use this for? It sounds like a good "cheat" for rapid fire in games. Are you planning to put the circuitry inside the mouse and add an extra button to it, or what?
