Thanks for the info and all the feed back. 3

I was merely trying to help and get more people to start building coils, and with a means of generating and testing their results.  With this info, I think it is possible that the more people build coils the quicker results can be posted.

Re: The RPM counter mod, the circuit look simple enough, one can build it, take the pic and the code to any electronics repair shop and I think they will be glade to program the pic (maybe for a small fee). Itââ,¬â,,¢s maybe a good idea to do the mod and post it.

On my side I was just looking for a decent generator, which I now got from you, (need to test it), a Scope I got last week, so now lets play !

100% in agreement.  So tired of seeing 555 timers.  They will never get OU with that. 

What uC brands are you using currently?

My fave uC so far is the PIC controller.  I have a C compiler for it.  pluss I use the Borland C++ Builder compiler for Windows.

If you look back to page 12 reply #228, X posted a PDF file with the circuit diagram for the 3 frequency generator. It uses three IC's.

You might have the pictures mixed up. The picture that shows the small circuit board that I think you are talking about has a different coil setup (single stage). The one that we are discussing (I think) are the pictures that were supplied by X in the PDF file. He is using three separate coils connected together.

Ok --- if this is the case, then I apologized for the insinuations, however remote, and misunderstandings.

This thread is somewhat difficult to follow sometimes.

I'm not saying that you cannot build a circuit that will get OU from a 555.  A 555 can be rigged   as an oscillator and if that's what you need to do the job then so be it.  I was only saying that, if that is a 555, then there's no way you can get three independent frequencies out of it.  However, it seems that this thread is not about the device in that video.  It's about the one in then ?TPUv4_tests1.pdf? file that was posted earlier.

great program here called "audio test bench"
has a oscilloscope, spectrum analyzer, tone generator, frequency plotter.

maybe will be of some help.
