Hi Joerg,
<grin> I picked up some industrial shelving at a local auction.
They are 7' tall, 18" deep, 42" wide "bays". I have 6 bays
assembled (currently). I.e., 21 feet "wide". Shelves are space
about 6" apart, vertically (i.e., 12 shelves * 6 bays = 72 shelves).
That doesn't count the 4 roll top cabinets in which I store

Does your e5 multimeter resolve microvolts? If not, it's useless for
designing thermocouple stuff. Can it measure resistance to 0.02%? That
is useful too.
If all you do is muck around with uPs that have 8 bit ADCs, a cheap
meter is almost good enough.
One cool thing to do with a good DVM is measure voltage drops in PCB

Hi John,
Ha! I suspect that would work -- in "his" case.
I've been working on a filter that, so far, seems to work
quite well. If I tell it *not* to look at IP address, name,
organization, etc. (i.e., all of the "easy" things that can
be manipulated) it still manages to find every targeted post.

Yes I think it is at the edge of what PIC can do...
I even tried a 100 mS delay loop after EACH I?O related instruction...
No difference.

If you mean 'reception' in the sense of the target perceiving
a sound, I agree. Indeed the subject would temporarily lose
the sense of vision and hearing, so no new information can be
received at all.
The modulation is closer to ~16 Hz (but on reflection is probably
a complex waveform for maximum effect). The target would lose control

Exactly, I tried all clock speeds, and it only works at 16 MHz or lower.
I think this PIC is not able to do I/O that fast in a reliable way :-)
Yes, well, I like simple circuits, adding all sort of stuff to compensate for hardware errors

Hmm, probably a silly idea with a mistake. But if you could reference
the signals to some voltage half way between the supply voltages (call
it common). You could then use the summing op-amp circuit. Then
invert back about the common point and remove the DC offset at the
end... sounds like a lot of trouble just to add two voltages with

Hi Martin,

These invariably break. :<

"Any" 5" floppy leaves me exactly in the same predicament. :>
