Have you ever seen a common water fountain hat was modified to
produce hot water? A second coil is added, near the condenser to adsorb
heat to provide hot water for a bathroom sink.

Tell you what, Michael, buy one of these ACT units and give it a proper
work out.
I have one and say it does what it claims to do.
You don't, and appear to be basing your views on 'experience' which is
years out of date.
Or you could just visit a decent battery shop and see what they use these
days.

And you think there are no US citizens who say bad things about your
country? But perhaps you'd wish them silenced. You certainly give the
impression of not wanting to allow others to have their own opinion.

The one that was mentioned by model number was quoted at 399 British
pounds. I have better things to spend money on that overpriced toys.

Yawn. You don't know me at all. It doesn't matter, though. I'm

Mine was used for pro purposes and in no way a toy. And was worth its
cost for convenience alone - your dinosaur type wouldn't fit in a pocket.
However, the one I have cost nothing like that much. I've had it for
several years. This appears to be the latest model - and seems to be well
regarded in your country.

Perhaps. But I've seen them.
Some years ago VCRs were redesigned to, at turn-on, scan the broadcast band
for a station with an embedded time code, and set the clock. These were
usually NPR stations.

I do. I have two atomic clocks.

Dunno. I haven't used a VCR in more than 20 years :-/
(The one that still is in use here is only used for playing
prerecorded tapes)

I had one here -- but it always kept losing signal. So, you
get a false sense of security *thinking* it is telling the correct
time -- only to discover it wasn't. I guess they are sensitive to
where they are located/oriented. Given how "unattractive" this one
was (think: functional not decorative), the choices for where it
could acceptably be sited were limited. So, it got relocated -- to
the trash. :<
(It *was* fun, though, to watch it go into "set" mode... minute hand
sweeping across the face of the clock as if it was a *second* hand...)

Such clocks are best kept away from computers and other sources of EMI/RFI.
Once you find a clean spot, you should be okay.
Those with LCDs usually have an indicator that shows whether the clock has
been recently resynched.

i got a desk lamp from ebay like the one in the image link below. the
bulb is held up by two adjustable telescopic rods, exactly the same
type as you would find on the aerial of a FM radio. they are metal.
i saw the double insulated symbol on the bottom, which go me thinking.
how did they get the wiring through these rods double insulated, they
are pretty thin. then i examined the rods. they had joints in them.
they werent even hollow! there was no wiring. they were the
conductors.
a quick check with the meter gave 20V AC. thats how it was designed
to light the bulb .
my question is can you have the double insulated symbol on a product
with exposed 20V AC conductors?

I'd guess because 20 volt AC is considered safe. A 20 volt AC power supply
could also have output terminals etc which wouldn't conform to mains etc
voltages. The 'double insulation' is to help prevent mains appearing on
parts you can touch easily.
BTW, it's more likely to be approx 12v under load.

Because humans aren't likely to be electrocuted by 20V, AC or DC.
But this does raise a question... What about insulation between the primary
and secondary windings? Its failure could put line voltage on the secondary.

Depends on transformer design - assuming it does use one.

I doubt it's the cable. Have you done a search with your

When this happened to me once, I just reset the Uverse receiver
and all was well. Unplug it for 10 seconds, or press and hold the

As I remember, early Roland units used the 3 inch Hitachi 360k
byte minidisc. Electromechanically, they looked like the 5 1/4 inch
DD drives. (Half the bit rate, and 300 RPM). Other major users of
them were the Amstrad computers in the UK. And, I think, fancy sewing
machines of the time.

610 turns of 40AWG / 45 SWG wiring in 4 "layers" anyone experience of such
winding and thoughts on resulatant (lack of) structural integrity,
slip/sliding turns with temp cycling/magnostriction etc leading to failure.
I've never seen a transformer design brief, so perhaps interesting to others
on that aspect alone

some general info including bank winding, I've only ever seen on high DC
chokes so structurally sound

Not sure what you are getting at. According to the winding winding
diagram and notes, the 610 turn winding is machine wound in a 'bank'
winder so it should be tight and even. I would expect that the #40AWG
wire is 'served' with polyester yarn which gives it a high surface
friction so the turns tend to lock together. Finially, I imagine the
finished coil assembly is vacuum 'varnished' to seal out moisture and
fill all air gaps as well as lock the whole assembly into a solid
mass.
I am surprised to see bank winding is back in fashion; we used to bank
wind torroids 50 years ago to give minimal parallel capacitance to the
inductance, but that seemed to fade out when ferrite pot cores
replaced powdered iron torroid cores through the '60s. For very low
capacitance coils we would then use 'Pi' or 'universal' wound coils,
but they too must be flooded with a sealing compound to lock their
rather frail structure that relies wholly on wire tension for
stability in the 'as wound' state.
