This is all I got, I cannot afford a new one. I can't work because of my eyesight but it isn't quite enough to give me disability, even though I would not be able to run a cash register now.
 
Anyway, we got hit with bedbugs. Two schools got closed over it. It was an epidemic or whatever.
 
Anyway, my laptop is infested. I have researched and found that when exposed to temperatures of 135 F for like 45 minutes it kills them and their eggs. The government and the companies who do this assure us that this is safe. It probably is if not running.
 
I just checked the oven, the lowest it will go is 170 F. Is that safe for a non, running (at the time) computer ? Could it damage the screen if by nothing else but expansion and contraction ?
 
We are about to bring in new matress and whatever, but anything happening to this laptop IS NOT AN OPTION.

Don't rely on oven gauges, I nearly came a cropper using what I thought
was a low temp set oven. Place a thermometer on insulation at the bottom
of the oven to check first. I had to leave the door open a crack to get
low enough temp

Consider Isopropanol, but check with the handbook first to make sure it
will not damage any plastic components such as the screen. If there are
parts of the laptop that might be harmed by liquid, leave the machine in
a sealed plastic bag with the Isopropanol soaked into an absorbent pad
underneath it and let the vapour saturate it for a day or two.
 
Be careful to make sure all the vapour has dispersed before switching
the machine on again, Isopropanol is very flammable and the vapour could
explode.
 
Usual disclaimer: at your own risk.

Why can't you treat the laptop the same way you are treating the rest of
the place?
 
I've never had them, thank God, but I have seen info about them and the
temperature thing is supposed to be for real. It is a way to treat your
entire apartment in fact as insecticides don't work very well. It seems
to be hard to get the chemicals into the spaces where the bugs hide.

The dry ice thing is interesting but, it seems to be a way to attract
them. Yes, you can kill the ones you attract, but with a bed bug
infestation it seems you need almost 100% kill otherwise they just breed
and you are right back where you started.
"An individual bed bug can lay 200 to 250 eggs in her lifetime. The eggs
hatch in about 6 to 10 days and the newly emerged bed bug nymphs seek a
blood meal."
I also found 118* for 70 minutes or 122* for 20 minutes.
I'd rig up something and do 118* for 2 hours. That seems much safer
than 138*.

That is a reasonable statement.
But is it correct?
 
I only speak facts.
And I'm very reasonable since I'm a logical thinker.
 
Most iOS users appear to be so inextricably emotionally attached to
whatever the Apple Marketing Machine tells them to think, that their own
words indicate that they can't even think facts on their own.
 
Contrary facts seem to befuddle them.
But the Apple Marketing Machine message soothes them.
 
So, maybe it is true that the Apple portrait mode ends up with superior
results in the final form (that is, in the photo itself).
 
Maybe it is true.
But maybe it's not true.
 
Has *anyone* shown facts either way in this thread (or in the thread
dedicated to this topic)? Nope.
 
So everyone is just guessing.
 
What we need is very simple, since it's a fact that both Android and Apple
iOS phones have portrait mode.
 
We need to find a reference that does a blind test of the results.
It's pretty easy to do the test.
 
1. Person 1 shoots a set of portrait mode photos with iOS.
2. They shoot the same set using Android under the same conditions.
3. A different person, a digital photo expert, compares the results
 
It's a simple test to run, and, depending on the conditions and the
expertise of the digital photo expert, they can pronounce whether there is
any meaningful difference in the quality of the results.
 
It's a valid question.
Does anyone have a pointer to such a reference?

I just did a 47" LG repair and was surprisingly straightforward. I followed the video (was a very similar TV) and took around hour and a half. Having a friend to help you is great though especially when lifting the LCD out of the frame.
 
The room I needed was a small (single) bed and a little table to place the TV when disassembling it.
 
Only one led had blown so I ended up just short circuit'ing it. You can tell a bit that the background is darker but worked well.

Rotating or changing the antenna while receiving a program is only
required if the signal is lousy and the user is trying to improve it.
No need to rotate the antenna if the signal quality is good. If they
were recording a lousy quality signal, I would think that rotating the
antenna might improve the situation rather than ruining the capture.

Seems that capacitor is most often used in electronics for about the
last 50 to 60 years ,but condenser stuck with the one that goes across
the points on an engine.

I don't actually see the rest of this thread, did this question get an
answer?
 
The reason the resistor is there is to limit the current in the coil
when the ignition is on but the starter is not engaged. When you crank
the starter the batter voltage is low, so the resistor is cut out of the
circuit by a relay or switch to give a good spark. The rest of the time
the resistor is there to limit the current when the battery is at full
voltage.

It was popular for industrial and commercial sound systems. It was a
US company, and I've seen their equipment for decades. I've been out of
the business for years, so I don't know if they are still around.
 
Some stadiums used their equipment, with thousands of watts of
amplification, with each amp driving a single zone. Some had N+1
installations that would automatically switch a spare amp into service
if needed.

The theory is that the fire can be kept going with the air coming in from
the compressor and the air pressure of 2psi will push the smoke through the
vehicle plumbing.
 
The caution is that most air compressors don't have a regulator that can go
that low reliably, and you don't want too much psi or you cause leaks.
 
I wonder if a diesel glow plug and hookup to the car battery will be better
for generating the smoke from the rag soaked in baby oil (he said mineral
oil is the same thing I think).

They may work if they have about 2psi of air pressure (or if it can be
bottled somehow to leak 2psi through a 3/8ths inch vinyl hose.
jurb6006@gmail.com: Apr 28 03:31PM -0700

There's an easier way to find a vacuum leak.
 
Disconnect the throttle control motor and spray the hoses with ether, which is starting fluid. When the RPMs go up, there's your leak.
 
This will set a code so if it is OBD2 you'll need a method to reset it.

Around the engine yes, but there are vacuum lines running all the way back to the gas tank. I had a small evap leak code on one of my cars and it was a bad gas cap. No propane or ether would induce an rpm change back there.

Use a propane regulator to regulate the pressure down to the 2psi
range., and yes, most baby oil is "mineral oil" and yes a deisel glow
plug can be used to make the smoke - just make sure it is a 12 volt
glow plug, not one that is connected in a series string.
I've got a fog machine - a little more elegany solution with less
danger and still to a degree DIY - and a lot cheaper than the "made
for the job" unit.

Not sure what the actual pressure is but it is enough to disburse the
smoke throughout the system and not enough to damage anytging -
particularly if you use a rubber glove as a "plug" on the intake
system.As long as you are not "given the finger" by the glove, the
pressure is safe - and you control it with the "trigger" button. I
have not made the custom adapter yet, but I plan on making a sort of
"heat exchanger" to fasten to the outlet to cool it before connecting
the hose. An aluminum or copper "pipe" with fins fastened or machined
on it.

What, if anything, are the markings on the caps themselves?
 
You ought to be able to screen a modern film cap to within a very few percent of the OEM values, go high on the voltage parameters, and go from there.

also consider in many tube applications the coupling cap has plate voltage on
one side like 250V and feeds a 100k grid resistor on the other side.
 
It doesn't take much leakage to upset the grid voltage.

Rather than just berate him you could try explaining that burning
plastic and wood and especially wood with various paints and varnishes
dumps incomplete combustion products into the air. Large scale burning
of waste is done at high temps that completely burns to CO2 and H2O so
there is much fewer toxins in the air and the ash. But heavy metals and
other toxic compounds remain in the ash. With industrial processes the
ash is treated like what it is, toxic waste.

Sounds like a good reason to tear computers and such to pieces and
dispose of the components. It takes maybe 5-10 minutes to disassemble a
computer to circuit boards and small boxes and sheet metal. If there is
no law against tossing pieces, then you are good to go. With RoHS there
is very, very little harmful substances in electronics now.

It is *very* easy to control manufacturers. Don't buy their stuff. If
we don't buy it they will stop making it. If you don't buy it you don't
have to worry with the waste.

Even the Catholic Church - not known for open policies and easy acceptance of alternate truths has a term for this sort of situation:
 
Invincible Ignorance.
 
Old School is a self-admitted thief & polluter, generally a fool whose roots are firmly set in the 50s, believes in the concept of "the good old days" (they never were) and is pretty much a lost cause. Not much short of an intellectual cattle-prod will get through his shell, and that only by repeated and assiduous application.

Anyone have a good idea for making a smoke machine?
 
My car is 15 years old, and the buna is getting old and tired but they
don't make a single kit of all the rubber parts which would be the easy way
to avoid making my own smoke tools.
 
I keep getting a P0171/P0174 (bank 1 and 2 lean condition), which, for my
engine, almost always means a crack in the complex hoses, tubes, and pipes,
so I want to see if I can build my own smoke machine for about the cost of
one diagnostic test by the pros.
 
A single professional smoke test is about $150 based on a dozen calls today
(where most charge a flat diagnostic fee). And the dealer price for
replacing all the hoses is estimated at far more than that one test.
 
I don't want to debate those two points here though (the pro diagnostic or
replacing all the rubber) because my intent here is to ask for advice on
building my own smoke machine for about one hundred dollars.
 
Just generating smoke is easy with a diesel glow plug shoved into a paint
can with glycerin in it, but you have to generate dense smoke and you have
to pump it under a few psi through the engine hoses.
 
Have you built your own smoke machine for around $100 or less?
How did you do it?

There are a lot of videos on youtube that instructs in such a project. Smoke machines are extraordinarily handy in "smoking" out leaks.
 
My son's Jeep Grand Cherokee has about 300K miles on it and needed to pass emissions (which demands no CEL). My buddy has a pro machine and found seeping hoses, mostly around back near the tank. No smoking gun (yep) but a lot of tiny issues that an old high mileage vehicle will have.

There are a bunch of sellers on ebay providing a pretty good device for $80 including freight. For the time and parts, you can't beat this. They also include a pressure regulator to make sure you don't blast anything in the evap system.

Fast answer as I run out the door. Yes, there's a balun inside. This
is the BNC version, but the phono plug variety is the same.
<http://www.cctvforum.com/viewtopic.php?f=6&t=29652>
Scroll down for the wiring diagram.
 
I've used these by the bucket load for security camera installations.
Plan on about 5% of what you buy being defective in some manner.
 
However, they are NOT made to handle DC. The transformer shorts the
line at both ends. See wiring diagram above. Also, there's no such
thing a speaker wire as I've seen speakers fed with almost every gauge
of wire available.
 
Perhaps it would be helpful if you disclose what you're trying to
accomplish and what you have to work with? There are similar device
made to handle DC over (for example) CAT5 without shoving DC through a
transformer (and causing the core to saturate).

2-pin microphone plugs and sockets make excellent DC power connectors - low cost, polarised, short cct proof and very sturdy.

Burnt contacts in the switch, or loose and corroded wiring to it.
 
Failing armature, commutator or brushes in the motor.
 
Maybe other things. But that's where I'd look first.

Looking at that image, it looks like a copy/clone/license of another
brand called 'World Dryer'.

Lenny:
 
Contact me directly, if you want to see pics of an outdoor eve install HD-8200U that isn't going anywhere. The antenna's are larger these days.
 
Although I used an Eagle Aspen ROTR-100 and a bearing that both aren't available anymore, I'm really happy with the install.
 
I didn't quite finish the install in terms of the minor details. The Rotor has a North position and you have to decide if your going to magnetic or real north so, I'm not calibrated yet.
 
I put the rotor on top of a stainless split collar,so the rotor can be rotated after the fact
 
I used Black oxide collars for temporary aides to install the antenna. All U-bolts are stainless. The guys are non-metalic and made of Phillystran and the hardware (like turnbuckles) is mostly 316 Stainless
 
There are two types of gold annodizing and one is really bad.
 
Two things that I would do differently are: Use a fiberglass mast on the antenna side of things and powder coat a couple of the clamps on the rotor.
 
You MUST use anti-seize for the stainless bolts. I used a small piece of siameze RG-6 satellite wire from the antenna to inside. The Eagle Aspen controls the rotor via Coax. I chose not to put the antenna on the same coax.
 
The Aspen rotates like 460 degrees, so it prevents having to go all the way around at times.
 
There is also 99 presets. Enough for every channel.
 
So, that's what I have to do: Orient properly so TVfool agrees and set the presets to the channels. I want to do an an antenna combine with a single channel antenna and get a custom combiner made and installed.
 
An IR to RF repeater works fine. There are lots of ways to do multi IR including over Ethernet.
 
The "bad thing" about this rotor is that the displayed position is the "desired position", not the current position unless the motor is stopped.
 
But this particular unavailable rotor has an index so it will never get out of sync.

Who are you kidding? Paper caps were already failing after ten
years of service.
The Sprague "bumble bees" and Black Beauty capacitors were
already known failures by the '60s.

They might be perfect for a project I have, except I want to use them to
transfer power of around 12 VDC @ 1 amp between components. Will these

Yes, and yes, it would.
 
Keep in mind that an RCA plug is a particularly wretched option for transferring power as it has exposed surfaces that may be shorted very easily. Yes, it may be only 12V, but still not a good idea.
 
I suggest either you use a standard barrel-type plug as with many wall-warts these days, or a phono-jack such as what was used in bygone days. These are much more difficult to short.

I did see some that looked to be the same with the word balun in it. I
doubt any of those would have an actual balun type of transformer in
them. At the price they show, I would give them a try, especially
looking at the ones that do not hae the word balun in the description.
 
They probably use the word balun to describe going from a ballanced 2
wire system to one that is not ballanced.

These *are* transformer-based devices and not designed for any level of current other than AV signal currents.
 
Apart from all that, using an RCA jack or plug for the stated purpose is just not a very good solution in the first place.

Customer wants a complete TV antenna with a rotor installed. I used
to do a lot of these so that's no problem. However the catch is that
depending on where they feel like hanging out he wants to control the
rotor from two different levels of the house. I've never tried to do
this before. Someone else suggested that I install a control wire to the two locations and have them move the rotor between the two. I know that channel Master makes a unit with an IR remote but I would need an RF based remote to go between floors. And I'm not a big fan of Channel Master anyway. Are there any RF based solutions for this? And is the equipment consumer or commercial grade?
 
Also back in the day I used to install Alliance rotors exclusively.
They were a real quality product and I never got married to one of
them. I know that Alliance has been gone for awhile now but is it true
that the only ones that are now available are the crappy Chinese
Philips rotors with the plastic gears that break in a windstorm? Is
it even possible to buy a good quality rotor, (besides a really
expensive Ham job) anymore? Lenny

Many rotators now have IR remote controls. For example:
<https://www.channelmaster.com/TV_Antenna_Rotator_p/cm-9521a.htm>
<https://www.google.com/search?tbm=isch&q=remote+control+antenna+rotator>
Put and IR repeater between floors, buy a few spare remote controls,
and you're done.
<https://www.google.com/search?q=ir+repeater&tbm=isch>
If you want quality, you'll probably end up with a ham radio type of
rotator, for plenty more dollars.

Any, repeat, any reasonable insurance company that has any, repeat, any experience with old houses will accept K&T wiring as a matter of course. Our house was built in 1890, and is by no means the oldest house in the neighborhood. Visible from our front door are houses from 1850 through 1963, with the preponderance built from about 1895 to about 1915. All but the 1960s house *will* have K&T wiring in them. The 1963 house will have ungrounded NM and thin-gauge grounded NM wire - no prize there either.
 
Our insurance company did send an inspector to check our wiring if only because we have 'full historical replacement' insurance. But we got a clean bill and no issues or additions to our premium caused by vintage wiring still in use (lighting circuits only). We do have a 200A service, and extensive new wiring, by the way. Not as if we are Luddites.
 
Any company with such an exclusion would eliminate 2/3 of Cheltenham Township from coverage. Our oldest occupied house is from 1689.

Thanks for the info. Here in Canada it was getting harder to get
insurance for K&T back in the early 00s, but I sold my house before it
became a problem, and - as you say - there are probably enlightened
insurance companies who will cover you once the house has an electrical
inspection.

It would be nice if all properties installed electrical conduit. But nearly all residential wiring, BX, MC, Romex (copper 12-3 or including a super-neutral 10 wire instead) that's been installed is attached to the walls won't pull anymore. You'd first have to get behind the walls and un-attach at each and every attach point in order to re-pull. Even from branch to panel.
