Don't worry! These people will just buy another microwave, then
another... and so on... Still, I suppose this group IS d-i-y, so some
people will try anything! From the web:


"The vapors or fumes released from most DVD's and CD's while
microwaving them are TOXIC. Do not do the above unless you have a
spare microwave, as the fumes can attach to the walls of the
microwave, or cling to your food."


Just because some ignorant fool claims something, doesnt make it gospel.

If you zap them for a second or 5 and dont get the plastic even warm, that doesnt happen.


But by recommending this idiotic misuse of quite a high tech piece of
kitchen equipment, you're encouraging the even more foolhardy and they
might well leave a CD in for longer, maybe much longer.

Like I said, in a newsgroup that specialises in DIY you would be the

trying to justify completely the wrong tool for the job, when the
completely right tool is available right now at hundreds of outlets

it will cost you peanuts to get another from a yard/garage sale.

The amplitude of the standing wave will rapidly increase until
the air breaks down and you get arcing somewhere in the oven.

I know two people who quickly wrecked their ovens by doing
this - no more heating. I guess the magnetron was wrecked, but
I don't know the mechanism that kills it when this happens.

I might speculate that the large standing wave could kill the
self oscillation in the magnetron, in which case its power
output as heat (instead of microwaves) could increase by a
factor of 3, and that might rapidly melt some of its innards,
which are shaped into tuned cavities. Just guessing though.

I do it all the time: None of that happens. I am always taking the food
out before the timer finishes and then shutting the door on an empty
microwave. Nothig happens, nor is there a warning not to do it.

I therefore conclude that the waveguides and magnetrons are desinged not
to draw power when the effective endpoint load is a pure reflection. It
can be done although I forget how.

But IIRC the actual 'anode current' (as it were ) of the magnetron will
very according to whether or not its matched into the load properly - if
it isn't, the current drops.

I am not sure that's how a magnetron behaves... but I was never that
interested in radar and magnetrons and its been a long time..

How long have you left it on for though? When I do that I turn it off again within a few seconds. What if you left it on while you ate your dinner?

It restarts automatically when the the door closes? Ours doesn't you
have to press START again.

There were certainly warnings on early microwave ovens about not
running them with nothing in them. Perhaps modern ones are more
robust and/or protected?

In theory you can, but decent modern designs allow for that.


Corse all bets are off with the cheapest **** from china.


even the cheapest **** from, china has to be essentially protected
against anything a consumer can put in it because at some point a
consumer will..


Will it overheat as there's several hundred watts of microwaves
with nowhere to go but the dummy load in the magnetron?


Normally not.


Not sure if there is no 'load' the magnetron will draw much power at all.


I thought they produced the rated output no matter what.


Doubt itl, where is that energy going to go when the microwave is empty ?


That's the problem. The energy inside the oven will increase until something melts.

The magnetron doesn't know if there is water in the oven or not.


It must be possible to measure what its putting out.


If they bothered putting in safety features.

Then if the microwaves aren't absorbed, they bounce around and come back to the magnetron where they're absorbed by
the ballast or whatever it's called.


Not clear what you mean there.


As I understand it, there is a hole at the side of the oven cavity. Behind that hole is a magnetron that produces microwaves, and next to it something to absorb any microwaves which happen to bounce back in there, so they don't damage the magnetron. There's some kind of T shaped thing between them to direct the microwaves the right way. Now if the ballast can't absorb all the power the magnetron can produce (which would happen if there is no water in the oven to absorb any), then something will catch fire.

You are not comparing like with like. A car is designed to carry
passengers and personal items, which could be just about anything that
fits inside, providing road safety and safety of occupant(s) is
maintained. Rooms are designed for activity as well as sleeping, in
that you have to walk, hop or skip into the room (crawling would also
work...) in order to assume your sleeping position on whatever surface
you happen to have contrived. Thus, reading a book is one of many
recognised activities in a room, such as eating, fornicating or
picking one's nose (not necessarily in that order), therefore your
analogy fails.

The laser shines through the pressed side.

And the lacquer is a spun coated thermosetting *plastic* resin.


ITYM its usually UV setting and its really not a plastic layer at all, its
just thick enough to level the disk for the printing.


Just a minute there denboi

Are you saying that you print on the read/write side of the CD

wenkkah!


You aren't very bright are you geof..

They use a negative blank to press the plastic which means the laser shines
through the pressed plastic.
The other side is lacquered and printed on.

Its all very simple really.


You will find single layer DVDs are the same, but not dual layer.
I will leave the exercise in how they differ to the reader.

Does anyone know if you can bust a microwave if there is nothing (or not much to absorb like water) in it?


In theory you can, but decent modern designs allow for that.


Corse all bets are off with the cheapest **** from china.


even the cheapest **** from, china has to be essentially protected against anything a consumer can put in it
because at some point a consumer will..


Will it overheat as there's several hundred watts of microwaves
with nowhere to go but the dummy load in the magnetron?


Normally not.


Not sure if there is no 'load' the magnetron will draw much power at all.


I thought they produced the rated output no matter what.


Doubt itl, where is that energy going to go when the microwave is empty ?


That's the problem. The energy inside the oven will increase until something melts.


Not when its designed to cut the power back when it sees it getting
reflected back when there is no effective load with the oven empty.

Thats how its done with modern microwaves.

The magnetron doesn't know if there is water in the oven or not.


It must be possible to measure what its putting out.


If they bothered putting in safety features.


They do, because you can be pretty sure that someone will manage
to do that, even if its just a kid stuffing up heating something up.

Or more strictly, the brand name products do.

Not clear if the cheapest chinese **** does tho.

It obviously depends on how expensive it is to do that.

Not much basically.

Then if the microwaves aren't absorbed, they bounce around and come back to the magnetron where they're absorbed by
the ballast or whatever it's called.


Not clear what you mean there.


As I understand it, there is a hole at the side of the oven cavity. Behind that hole is a magnetron that produces
microwaves,


Yes.

and next to it something to absorb any microwaves which happen to bounce back in there, so they don't damage the
magnetron. There's some kind of T shaped thing between them to direct the microwaves the right way.


I dont believe there is now.

Now if the ballast can't absorb all the power the magnetron can produce (which would happen if there is no water in
the oven to absorb any), then something will catch fire.


So it makes much more sense to measure what gets reflected
and cut back what the magnetron is producing instead.

And thats the way its done.

And it doesnt cost much to do that.

MM has clearly never put a plastic dish in a microwave. In fact it is

What I do know

well lawks a mercy!

is that microwave ovens are designed for heating and
cooking food, not destroying CDs. This is something that you do not
appear to know.


Actual;ly they are designed to sell. The fact that they heat things is
simply a way of selling them.


Another way of selling them would be to list on the box, "Can also be
used to destroy unwanted CDs".

Ever seen such inclusion listed?

OK - blööööde trottel

you say you lived in germany. What is a bottle opener called?


Flaschenöffner.

Next!

It's called a siebzehner


No, it's not, it's called a Flaschenöffner.

because a seventeen mm spanner is often used as
a substitute. Is that the correct job for the tool? No


That is correct, a 17mm spanner is not the correct tool for opening a
bottle, a Flaschenöffner is. I'm pleased you're taking my tutorials on
board.

Failing that, folk use a cigarette lighter


To open a bottle? Whew! What, you *burn* it off?

, knife or whatever else
happens to be lying around.


For example, a Flaschenöffner.

"Hey, Manfred, what is this tool for?"
"It's for opening bottles."
"D'you think it'd open mine?
"Don't see why not."
"Hey, it WORKS! Crikey, that's bloody clever!"
"Yep, we Germans know a thing or two!"

Nope. There is a big difference in the price of the name

I thought there was always some reflection (the waves that happened to hit the hole before the food), and magnetrons hated even the smallest amount coming back.
