Gravitational Engineering - What We Can Do Now

I find it somewhat humorous that old tv parts could help determing the SOG. It sounds wacky enough that it could work. It would also renew the garage inventor in American folklore. Someone head over to Sammy's Used Appliance store and make it happen. (send me a schematic, i have all of that equipment except the xtals. I will build this!) - MV<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>
Very cool. The next big hurdle (how will we actually Do the things we talk about here) seems to have at least an inital solution.

Thanks Mark,
LB

I'd recommend using a non-inverting CMOS bus driver IC's (don't use the open-drain/open-collector variety); connect all the elements in the package in parallel, load the output with the series connection of a ~50 pf variable capacitor (to fine-tune the freq), the xtal and a ~30 Ohm variable resistor (potentiometer with one end and middle connected) to the ground wire, also shunt that potentiometer with a ~100 pf capacitor. Bias the input into about linearity with pull-up/pull-down resistors and arrange a positive feedback from the point of connection of xtal and the potentiometer to the input througn ~1 nf capacitor (1 nf is not critical). Then adjust the potentiometer to max signal current through the xtal.

(Or use any regular non-inverting 5V CMOS element with a complementary follower made of mid-power FETs, or use an op-amp with high enough output current rating or with an additional follower circuit in the output - the choice of active element is all yours.)

I think you guys might be on to something. I am concerned about the proof however, in that there is going to be a lot of finger pointing about the response of electronic components. Particularily where capacitance is used.

Not saying it won't work. I'm saying you will have a hard sell once you have data that you think is viable.

Mac,
You are correct, sir. The burden of proof now rests on US. If you or anyone else lurking around out there even suspects that you see a problem with some part of this enterprise, please say something.

I have a question on that setup. What are you measuring and how is it calibrated. I didn't read anything about the calibration of signal readings corresponding presumably to some physical quantities. Do you have a model for linking measurements to physical quantities? This sounds like mearuring the speed of the resonant coupling of crystals. The non-screenable part may be due to self-excitation.

I'mwith Mark. I have read over but perhaps not fully digested your game plan. If I understand correctly you propose to excite a large crystal at a frequency that can induce gravitational response in a reciever crystal.

1 - Should you crystals system be encased inside a vacuum chamber?

2 - How are you shielding the reciever from EM from the transmitter?
