Hi, I was wondering what is the simplest 40Khz oscillator schematic to use for IR transmission?

Does anyone know whare I could find the resistance values for the 555 timer
so I dont have to have a POT.
Or is there a site I can goto to find the values?
My goal is to keep things a simple as posible.
Many thanks.
