Anyone here have difficulty dealing with this firm? I ordered parts
from them to build a kit, but the remainder of the parts needed are
outdated. I contacted them, but they take forever to respond and said
they would refund but that's been well over a month ago. Anyone know
how to get them moving?

If paid by credit card challenge the charge as "Goods not as advertised".
 
If PayPal complain to PayPal...
 
and so on...

Tell them that you will expose them in a world-wide-popular
electronics forum.

** That is not near as silly as it sounds.
 
Cos it actually happened to me, about 13 year ago - after I posted a fairly innocent complaint on usenet about a circuit idea published in an Australian magazine called "Silicon Chip".
 
Little did I know I was being watched.
 
Soon got a red hot phone call from the magazine with thinly veiled treats followed up by a letter from a Sydney based lawyer with an American sounding name and writing style: Lynden E. Hooper. It demanded a formal apology in the next 7 days posted on the same forum.
 
The letter spoke of "defamation act" plus "Chat room" and fair had me in stiches when I read it.
 
So I whipped off a reply of about 250 words, written in the style of Jed Clampet of the Beverly Hillbillies.
 
Never heard a thing back.....

Electronic equipment has a rubber like material on the handle.
 
It is coming off and I want to glue it back on.
 
What is best to clean both the plastic handle and the rubber-like material ?
 
What is best glue to use to put it back on.
 
Probably needs to be slightly flexible since the rubber-like material is
the hand grip.

Try auto paint thinners and re-glue with a rubber cement like contact
cement etc.

Much too high. In the UK, inflation from 1999 to 2019 accounted for a
price rise of about 72%.
<https://www.officialdata.org/uk/inflation/1999?amount=1>
You have to go back to 1985 for inflation to triple the value in 2019.

Looks like I should have bought one at the time. There's now way I'll
shell out 4x for it now. Oh well.

If you're talking a "plasma globe", yes I have one of those. It is
about 14" diameter and cost me $19 at Walmart about 15 years ago.
However, I see that even those in many cases appear to be somewhat
higher in price, but certainly not nearly as high as the luminglas!

No, I meant an ordinary light bulb.

John means a lightbulb with a tungsten filament in it which burns very
brightly when a current is passed through it. You have to have attained
great age, like John and I, in order to remember such obsolete atrocities.

But don't heat the filament, just apply a lot of high voltage, high
frequency stuff to it.

Yes, Ive applied clear incandescents to a HV source too! It can produce
a different display from an actual plasma globe depending on bulb vacuum
or type of gas used. One has to be very careful of the 25 watt
incandescents though if applied to high voltage. Some of those used to
produce x-rays because they were vacuumed but not backfilled! I think
manufacturers have corrected this nowadays, but 20 years ago they were
not backfilled.

Like putting one in the microwave.
To protect the microwave, also put a glass of water inside.
The lamp does not need to be in working order.

Part of that price is the size. If you must have a 15" disk, it's going to
cost you. 6" are about $25 to $30.

I don't think it's really 200% though. It won't run when it's not condensing. I think a small amount of heat is generated by the motor and fan, maybe friction of the refrigerant in the pipes, but the majority of the heat produced is the latent heat. It should be 100% efficient but it may not be much more, maybe 110%.
 
Where would that other kWh of heat come from, or go? Not into the air, because we've already agreed the air is cooled and reheated to effectively no loss or gain. The refrigerant is compressed, expanded, evaporated, and condensed, but again I don't think there is a net loss or gain.

I have not had time to really research it,but seems to me if the
condensed water stays in the room long enough to equal the room
temperature,
 
Then the total heat gain would be what ever the electrical power drawn
from the AC outlet would make. That heat would be mostly the power it
takes to run the compressor and fan motors.
 
There is no way for the power drawn from the AC outlet to escape from
the room except what may go through the walls.

Typically, it DOES reach room temperature (empty the tank every couple of days),
but the 'latent heat' also has to include the heat that evaporated that water in the first place;
you get heat out of the vapor that originally evaporated the recovered liquid-water,
and that shows up in the 'hot' side of the coils, it's not in the water-vapor any more.
 
Pumping heat of evaporation OUT of the airstream causes the condensation, putting heat into
the hot-side coils and raises the outflowing air temperature accordingly.

Here in Canada, on our national radio station CBC, we get a fellow named
Terry O'Reilley on the air with a show called "Under the Influence" -
which is all about advertising. Where this story is leading is he had a
great show on pricing where he talked about the above subject and
people's perception of prices and what influences them.
 
The episode is: S3E02 (Archive) - The Psychology of Price
 
Listen to it here:

Or go to the main page at and track down S3E02:
 
https://www.cbc.ca/radio/podcasts/arts-culture/under-the-influence/
 
I've been listening to him for years, lots of great info on how
advertising (both good and bad) influences us.
