Using the MAX038 Chip, I built a function generator that allows independent Mark Space and Frequency adjustments and Frequency fine tuning, with the future possiblity of integrating a phase locked loop.

The output wavform is solid. However currently only 0.2 V amplitude.

The chip is hard to find because its no longer produced, but was easy to hook up and has a very large range and the independent Freq and Mark adjustments are nice. FUTURELEC.COM has some for sale at $20 each.http://home.vicnet.net.au/~olaf/hho/FREQ_GEN_OPMEYER.jpg

If somebody could suggest how I can boost the output voltage. Please tell me how. Thanks.

the specification on the MAX 038 is at http://pdfserv.maxim-ic.com/en/ds/MAX038.pdf

Take a look at this circuit with MAX038 (http://babelfish.altavista.com/babelfish/trurl_pagecontent?lp=ja_en&url=http%3A%2F%2Felm-chan.org%2Fworks%2Fwave%2Freport.html) (Babelfish translation of ELM - Electronic Lives Mfg. (http://elm-chan.org/works/wave/report.html), it uses some old microcontroller to control the frequency and it's rather old (1996) but it provides 0-4Vpp.

I would like to modernize it with a PIC chip instead of that TMP chip and already had ordered two MAX038 from Futurlec. :)

What I'm more interested is to make an output using a vacuum tube due to its impedance characteristics (or so I'm told) that better match human skin resistance (hehe I guess you know where this is leading to - fancy zapper like circuit).

my consortium has the technology to make a frequency generator that covers 0 - 300 trillion htz.
here is our problem.... we cannot adjust it. (we are not electrical engineers)

is there anyway to make a fully adjustable frequency generator(micro adjustable) within that range?

Here's the thing though, how do you know you signal/frequency you have goes up to 300 THz (EHz?) and what creates this kind of vibration to begin with?

I'm trying to fathom the idea of an electronics circuit operating at 300 Tera Hz (or Exa Hz). I am not even sure there are standard components that would fit into that range, so we are talking exotic hardware from some underground lab, or grinding and melting elements (shiny rocks) to make your own semi-conductors, just like JB did in his early years ;)

Again what would be the nature of the signal to begin with, electrical, mechanical, photonic...?

secrets, secrets, all proprietary secrets my friend...
(and a little understanding of the nature of an electron... HINT!!)

Here's another circuit with MAX-038 and frequency control: Mondo Technology (http://mondo-technology.com/max80.html)

to answer your questions above, the only hint i can give you is that an electron has the potential to vibrate at ANY known physical frequency.
there are ways to cause ALL possible physical frequencies to vibrate at the same time. 1hz - 7 Thz Tesla knew exactly how to do this, and i think he developed that first, and then worked backwards from there into isolated frequencies and vibrations.
after this, all higher frequencies rest in the Quantum realms and cannot be replicated by normal physical means.

all of this knowledge has been around since pre-flood times... even before egyptians and sumerians. the Ark of the Covenant is a perfect example of the Quantum frequencies being used... and NO it was not made of regular gold, and it did a whole lot more than just zap people.

Hmm, am I to assume that you firmly believe the theory there is an electron in the first place? :)

How would you induce such a broad spectrum vibration, 0 Hz - 7 THz - wouldn't that mean that you would have to vibrate at those same frequencies first to create resonance?
Thinking in electronics terms, it would not be a conventional signal generator then, you would need to have an infinite number of channels in that range, or some way to produce primary frequencies and harmonics at the same level at the same time.

I thought that Tesla used sort of a snowball effect, slowly building up the vibrations by amplifying the return signal (effectively creating a phase conjugation mirror or did I use that term incorrectly?) It's that story about the pocket device he created and tested while in NYC on some building under construction where things started to shake pretty bad...

Are you suggesting that 7 THz is some sort of a limit to a physical vibration we can create in general, or is that our technological limit at this time?

Throw me couple of more bones, will ya? :D

this is the technology i was referring to when i said he "worked backwards to isolate the frequencies" he figured out how to do as you say
or some way to produce primary frequencies and harmonics at the same level at the same time. YES
only one specific type of input needed, and electrons will "sing" every known physical frequency at the same time. well, it isnt actually only ONE electron that is doing it, think of it like an electron "orchestra"

approximity 7 Trillion Htz is the known physical threshhold until you cross over into the Quantum Realms. then there are an untold number of Quantum frequencies.

was that a big enough bone? :whistle:

Would that imply that there is a "sweet" spot that needs to be "hit" with a tone for example and the whole thing would start resonating? Is this done mechanically or electronically?

If so then this sweet spot must be dependent on the chemical element and its resonant frequency, something that perhaps John W. Keely was applying back in the 19th century with his experiments?

Or is this element independent and it's actually on a sub-atomic scale? Wouldn't that theoretically resonate or even decompose all matter at once?

thanks, will keep chewing...

hi guys im needing some help with the math on my 555 timer im confused on one thing basicly to calculate the percent high time the equation is: r1+r2/r1+2r2 well the part im confused on is the 2 in front of r2 does that just mean r2x2 ?? i just wana make sure
:cheers:

r2x2 is corect
