Lords of the Ring

Well the mechanics of the coils have wound up all over the place, pulses have been tested widely, alot of materials have been layed down. So why not curve through space with sine waves and audio circuitry. The graphic of the microphones pointing inward to the spearker cone wasn't that far fetched and we haven't aired in this area yet. SM was was/is an audio engineer. Stands to reason this is good. Soft, smooth operation like an exercise into violin music.

Don't know why I left the concert hall to join in the paint ball games, but it was fun. And as Edison stated 'We know another way that doesn't work'.
So I am working on the 3 channel digitally controlled sine wave, 10 mip, 16 bit d/a output to a fet audio amp. Then the analog side will be covered.
I can even do PPL next step with a variance window.
If I could find 5 xr-2206 I would settle for that.

No problem, I build, you watch, we see, open source. Right?

I will find fet amp in a few.

Brilliant giantkiller! I think you got what it takes. You adapt to fresh ideas and have the resources to do it. Some have the resources but wont adapt they just get stuck in a rut. Its very much like trading stocks or forex. There are many ways to trade but 95% of people that try lose. The winners takes all because they cut their losses and let the winners win!

Put SM's bible in front of you and check EVERY word he says. Please make sure you make a kill switch. A microswitch with lever is a good start either hand held or mounted to a block of wood on the floor under your bench so it anything happens its like taking your foot of the gas and kills the PSU instantly. Put fuses in the main coils too. If you hit these 3 frequencies with precision then SM has warned this can turn into a bomb. I really believe this to be the case because his big mama device handles a kw or two easily. In fact he was able to blow a 70 amp fuse with it detuned and there is no way you will have chance to lean over your workbench and pull the plug its too late. When you read his bible notes it looks like he is going off on tangets. Absolutely not. Even the audio story has embedded information.

A pratical standpoint use a master clock, make division controller, use high quality very low noise mosfet Op Amps. Output stage should be class A power mosfet DC coupled but i think 4 watt a channel will be more then enough. This setup should run from DC to several megs if you stay away from coupling caps. SM adds this to hint:

"I last measured it at 35.705K at a really high level.
It is a good thing that I can't hear that high. But it does prove that my output transformer is capable of going up to 245K HZ.
Which I measured."

AND

"You know transistors just don't do well at those high frequencies.
They try hard but they just make all sorts of harmonics all over the place.
Dirty things transistors.
MOSFETS are better you know if you wanted to make an amplifier that behaved as though it was a tube amp but in a smaller size."


Well i think thats as clear as mud LOL

laters...

[innovation_station]

well im glad your mud is transparent cuz mine is a little clouldly just a wee bit dirtty too

is

well i just aint got the skills to play anymore  l8rz all

best luck

@bolt,
Thanks for the bolt of confidence.
It will run about $100.00 for the whole setup. The IDE, sample code and asm libraries from Parallax will have the answers. And that is the free part. Done this before, not difficult. Besides, Parallax is always good support. Especially when you give a little shpeil 'bout what you are working on. I got the whole device platform, plus some goodies, worked out from their site. I will go over it again tonight and call in the morning. Everything just plugs together. The boards are also in the the range of 1 to 3 inches big. Shweet!
I estimate 1 week till it's up. Till then, mind if I keep throwing design ideas out there?

I would not be surprised if the parameters of the coil physics aren't that tight as we have thought of them. Was just waiting for a natural break in the clouds instead of crackin' one myself.

--giantkiller. When we search for the truth, we end up where the answers are.

GK,

thats great that PIC board is the business! I could have great fun with that, programmer at heart me!

Will you publish your shopping list here? $100 seems like a small investment for a nice setup. I should imagine that because it is so flexible there is a good chance that whether this is the final solution or not these boards will figure...

also could do with a diagram for dummies like me showing how all the parts of the coil are connected in detail, saw your two previous diagrams. Or may be someone out there can whip up a 3D model?
