rc circuit is no way to produce a square wave.  rc circuit is by nature a filter.  a filter will destroy square waves, not make them.

What is the best and cheapest way to beat a square ware out of a rc circuit? Looks like the best way to lick some getting to the frequency problems. Transistors are to slow and weak there has got to be another way.

Hi,

If you are happy with about 4nsec rise and fall times, then consider building this simple circuit from EDN magazine Design Ideas section, see the attachment . I mean the second article "High-speed pulse generator has programmable levels". 

Sorry if this circuit is totally different from your original imagination (you have not included much detail on your square wave needs).

Get a 4069 hex Schmitt Trigger inverter IC and then you only need
one RC unit to build a working square wave generator.

Hi Stefan,

I am also trying to make a switching circuit to turn on and off mosfets to switch the voltage from some caps over a coil. Do you know of any good websites that explain how to use the IC?

I just tried a marx bank, It cascaded my mosfets, The fets can't take it- Oh bum. An alternator stator might be custom wired to pulse controlled by the speed of the alternator. I'll look at it, don't see any reason why it can't be done. But first I have to check my present circuit on water, I have decided I need to change over to stainless screen to get more surface area and am having a problem finding the screen.
In Super Capacitors abbarue posted a cap diode maybe in stead of a mosfet? And I am still looking at clipping the sawtooth of a rc, hope this generates harmonics.

Most of the circuits we are investigating are high freq. or high v or both. The government and big business know many of the secrets we are trying to find. They do not want us discovering these and have suppressed componets that can handle the required voltage and frequencies, have no doult government and big business have solid state devices that do exactly what we need to do and this devices are hidden so we have to find ways without them. This will include developing our own components and work arounds. Limiting what our circuits do by using what is availible is stopping us. I for one am not going to let them hold knowledge from me forever just out of reach. This is a simple thing generate power with a coil it has to be done. A power supply is the most basic need for any serious experimenter and all of you must realise how important it is to be able to deliver any required souce voltage and frequency at a matchable impedence.
