555 timer help
I thought this would be an easy project, but apparently it's a little out of my league. Any help would be greatly appreciated.

I am trying to breadboard an astable 555 circuit.

Input: 12VDC @300ma
output: 50-200Khz (anywhere in that range) square wave w/ 10:1 mark-space

No matter how I work the formulas, I can't seem to get it where I want it.

Thanks.
