Here's a Hackaday article about a 555-like circuit which operates high in the MHz region... with a pretty square wave at 50 MHz, and the waveform becoming noisier at higher frequencies.

74HC5555 from Nexperia USA Inc. hits 89 MHz, just so you know.

That is exactly what I was looking for for a project for a adjustable clock timer for microcontrollers, thanks for sharing.Vidura.

The great Nikola Tesla:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago go by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
