The shaking table, or base plate, is not a "non-moving mass", but is the
coupling factor which transfers the energy from the sum of all the other moving
masses from the strongest to the weaker. Another example of "majority rule", if
you will.
Remove the resonance frequency of this coupling fact

Dave,
The actual number is x.75 degrees but the program you're using (LH?) apparently
truncates the display. TBoltmon doesn't have this problem. Regardless, there's
much more to it than just which program you use.
I never finished this article, but it explains a few things about the TBolt
1620
I understand it means parts per trillion (10^12), but can someone tell me what
the trace is measuring? Is it an indication of how far off frequency the osc
is at incremental times, relative to what the unit thinks is correct by way of
PPS (over time)? Or point me to reading material please. I
I've been observing my Temp trace for a week or so now. Seems like my sensor,
if I let the unit cool off to room temp, starts at a real temp say 25, then
ramps up to about 37 or so degrees and then goes into this mode where it
switches between 2 one degree levels, 35.7 and 36.7. There is also
And, in fact, the mass of the "shake table" has a big impact on the lock time,
as does the mass of everything else besides the mass of the pendulum weights.
Would there be a natural resonant frequency of the non-moving masses (shake
table etc) that could prevent lockup?

If 99 out of 100 metronomes were slower than the one fast one, I don't think it
would rule. I think you're overlooking the fact that this is a "greatest

Not true. It depends on the strength and reciprocity of the coupling.
If essentially equal as with the metronomes which are coupled pendulums
(the math exists for this), the systems will come to some combination
frequency, though as has been mentioned in a many-oscillator system
there may be
Maybe not. We need the math that describes the phenomenon, but it
won't come from me.
Consider the way that television sync pulses synchronized the sweep
oscillators. The pulse has to get there before the oscillator cycles
on its own. Similarly, the movement of the common base has to occur
before
Hi
The effect applies to a lot more than metronomes.
Where things lock up depends a lot on the level of coupling. In some cases they
arrive at a compromise. In others they "decide" to lock at one or the other
side of the average. The decision in that case is fractal, so predicting which
side
Compromise.

Hi
Some of the similar boards have *lots* of 0.5 Hz coming out on differential

Split off to front connector and "cellular interface" so there is 2 places to
pick of 0.5Hz.

Hi
The issue is the efficiency drop off as the voltage differential goes low. The
ebay boards normally don't have any heat sinking on them. The LPRO pulls full
