Hatred does no good to anyone, and in particular it distorts the

Thank You in advance for your input

To create a nonsilly em wave at this frequency, the antenna would be
huge (as in miles long) and the focus would be correspondingly fuzzy.
If the antenna is small, all you'll get is a local electric or
magnetic field, not a real electromagnetic wave of any consequence.

I'm thinking that not only is it impossible to focus a 25 KHz carrier
with a small antenna, it's probably not feasible to send any usable
amount of signal 50 feet. The magnetic field from a dipole coil falls
off as distance cubed - bad news - and electrostatic coupling is
probably worse.

What are you trying to do?

You can get well past 50 feet. A lot. But you are right, for a truly

I have on the negative input a 10K resistor 10Mfd

on the output. As said before the OP-Amp is powered from the 5V logic
supply via a 1N4148 diode and 10Mfd capacitor.

Signal goes to the non-inverting input presumably ?

LF353s are not intended for 5 Volt operation. A very poor choice. Why not use the
12V supply ?

Do you have any overall HF feedback around the Op Amp? Depending on the
frequencies you're interested in (I'm assuming something near the audio

be diagnostic.

Where would I place this, please?

Hmmm- I will call you on that, Mr. Woodgate. Cite any post in which I
defamed the character of the entire support base for Bush. I do admit to
using such terms as "duped morons" and this descriptor did seem to have
some scientific justification in the polling results that 70%+
considered Bush to have the best 'plan' for Iraq while at the same time
roughly the same percentage admitted to not having a 'clear' idea of
what the plan was. This kind of thing does suggest, that for some
inexplicable reason, a certain amount of mindless ( not 'clear')
hysteria ( feel 'strongly') has been incited- and the method of
incitement is called 'fear mongering'. Your posts on the other hand lack
nothing in the way of ignorant entertainment value. I especially enjoyed

I am pretty sure John assumed you don't ride horses when he assigned
the lower probability to the exploding battery pack. All computer
lithium battery packs include a thermal fuse in direct contact with
one or more cells, so a cell explosion requires multiple simultaneous
failures including at least a low impedance short across the battery
and thermal fuse failure.

The above is not true. Thermal runaway is possible within a single cell.
See:

http://www.ewh.ieee.org/cmte/PES-SBC/Downloads/sWM04_LithiumBatTech-Valence
.pdf

OK, this article claims that it is a myth that protective devices will
prevent all battery explosions, and they are probably right. But they
only provide 2 examples of battery "explosions" including a single
laptop computer, and these incidents resulted only in minor burns.
Presumably the designed in cell overpressure venting features worked,
and these "explosions" consisted primarily of the venting of hot
gasses, which are not nearly as dangerous (or likely) as being kicked
by a horse. Even if the vent failed, the case of a lithium battery is
too thin to allow enough pressure to develop to cause penetration of
the laptop case when the cell ruptures. "Possible" is quite different
than "probable", and the "explosion" of a lithium cell is quite
different than the explosion of a roadside bomb in Iraq! But if you
are really concerned about the slight possibility of second degree
burns, how about a nomex lap pad?

All good points. The purpose of the post was to determine if events had
occurred similar to http://www.cdc.gov/niosh/face9939.html involving lithium
sulfur primary batteries.
These batteries do pose an explosion hazard. Imagine if the batteries in the
above case had been in a device cradled in a person's lap!
Perhaps the venting characteristics of LiIon batteries are different from
lithium sulfur primary batteries.

Looks like the user called it an exolosion and the battery
manufacturer called it one of 4 venting incidents in 144,000 cells,
which would be 1 incident per 9000 of their 4-cell batteries. Too bad
they don't reveal what the cells were, but they look to be fair sized,
perhaps D size similar to a Tadiran TL5930 with a capacity of about 19
AH at 3.6v nominal, but probably the less safe spiral wound
construction from another mfgr., having lower internal impedance which
increases the heating rate in the event of a short.

I think that the venting characteristics of these batteries differ
from the venting characteristics of your Sony 16550 laptop battery
cells in that the Sony cells are probably more reliable (but lacking
actual data to back that hunch which based on the large number of
laptop computers out there and the small number of incidents that I
have heard of), and they are definitely smaller, storing quite a bit
less electrolyte to potentially boil as the cell overheats, and they
contain a lot less energy to heat that electrolyte up with their
measly ~2 AH capacity. So in the unlikely event a cell should vent in
your lap you will most likely wind up with no worse than a minor
nusiance burn (depending on how fast you react and how willing you are
to toss that expensive laptop on the floor).

One would hope that the battery case and cover would be designed to
retain the cells during a venting incident (unlike the Medtronic AED
battery case/cover shown in your link), but for some reason I find
myself recalling the famous Ford Pinto gas tank explosions and their
leaked management memo with the calculation that it would be cheaper
to pay for the expected couple dozen additional immolated vehicle
occupants than to fix the gas tank design so it wouldn't explode in an
accident. Perhaps the nomex pad is not such a bad idea .

1. Two flip-flops, which (in my idea) are edge-triggered (level
triggered would be a latch), so the total thing would be edge

2. Two latches, so the total thing is an edge-triggered FF.

To summarize: is a MS-FF one FF, or two FFs?
