Microwave disassembley

You lucky man. Presenter of an appalling day-time TV show (which I might add, I've only ever seen about 10 seconds of in total) which may as well be subtitled "My mother is my sister and my Dad's run off with my brother. Can I get compensation?"

I vaguely recall seeing it when I was off sick from school, but I was too young for school in 1964. Could it have been shown later?

I really am pleased that I know nothing of this.

Could be. I wonder if they used it for colour test transmissions later on. However, that would only be three years because they went into production scheduled colour in 1967. Even so, I'm not sure that the SIDE film was in colour. I remember the participants looked like stereotyped research scientists at a government centre complete with short back and sides haircuts, pens in the top pocket and those expanding bands that draughtsmen wear that go over shirt sleeves to keep cuffs out of the way

You can buy it ready made "Rat zapper" or somesuch.

So you can!

Now how do I make just the squirrels go in there?

(I have redesigned my 'live squirrel cage trap. What must be dozens of times now. However clever I think I have been the buggers always suss it out first go; in the dark! All I managed to catch were the young ones and the odd mouse: the culprits just sit on the fence laughing, and waiting for the next freebie.)

Cheers for the tip.

Its only a couple of uF, but its enough to kill several people.

How does that compare with tazers?

Tasers are higher voltage, but lower capacity and much lower potential for a current. HT in the home is normally found in low-power devices like TVs, flashguns (and "home-radar" garage door openers, if you root in the same skips I do). If you take a zap from that, it's painful and the muscle spasm may cause you to leap through a glass door or off a ladder, or somethign similarly injurious, but it's _unlikely_ to kill you outright.

A microwave oven OTOH is a high power transmitter. Seriously high-power. So its PSU works with a seriously high power (and thus high current), even at these voltages. It'll have a damned good go at killing you.

Yes, it was one of the trade test colour films:

ON THE SAFE SIDE An Atomic Energy Association Film (U.K.A.E.A.) 18 minutes duration First showing 1st May 1968 Final showing 17th July 1973 A film showing safety precautions undertaken in a UK power station. Made In 1967. [Info from

power station above read high-voltage test lab, I's say.

Never seen it, but it was broadcast during period when I wrote "TV watching causes cancer of the eyeballs" on demands that wanted to know why I didn't have a TV licence.

It seems that nowadays that films made with similar intent are shown at

2AM - 5AM and that daytime TV consists of chavs "emoting" about their relationship problems, which most of them wouldn't have if they could communicate rather than grunt, whine and scream abuse.

Ah Steve, how is life in Tunbridge Wells?

I wouldn't know, I have no desire to live in chav central.

Brilliant - brought back memories of an old Dynatron with a hinge up panel wit 27 convergence controls.

Blimey, the chavs round your way must be incredibly affluent if they can afford to live in TW.

Even the chavs around my way would consider TW as beneath them. It is in Kent, which runs in second place to Essex as Chavheim. FFS they can't even speak English there.

Steve :-P

Talking out of your backside, mate!!!

The OFFICIAL (look it up) capital of Chavism is Gornal, near Dudley, West Midlands where 87% of the population under 27 is a chav.... and

77% of the population over 27....

Who says? Is there an OfChav now?

You mean, 164% of the peopleation is chavs, innit.

Ah, a Kentchav stands up to be counted.

Not too much wrong with all this advice, BUT: Be careful. Very careful! Microwave ovens sometimes described as 'One of the most dangerous domestic appliances ever made'. Reasons:

1) They are essentially a one thousand watt (or thereabouts) radio transmitter inside a box**. That's why there are essential safety door switches, and checking for unwanted radiation/leakage can be important. If it can cook a piece of steak in minutes etc. it can fry your hand, or worse, your eyeballs, and or some internal organ. So do not operate when it's open. Also make sure it goes back together properly when the cover is replaced, there are sometimes RF sealing devices on the edges and overlaps of the various panels. Tricky to get right sometimes; but essential! 2) Yes; there are dangerous voltages and the capacitor/s can store some of those as others have described. The transformer can typically provided 2000 RMS, volts which is then voltage doubled by a rectifier- capacitor to a peak of sometimes over 5000 volts. Strongly recommend that unless one is an experienced electronics, preferably one with radio transmitter training, technician be EXTREMELY careful. Or leave it alone. The cost of a microwave oven these days does not warrant IMO the risks of fiddling with something that costs well under $100! Recently a local 'big store' here had stainless steel smallish m.waves on sale for around $50 Canadian (About 25 quid!) And it wasn't an 'In store' or 'Manager's' special to get rid of stock. It was a national price in their printed circular! Have fixed quite a few units using background as communications technician/manager of some 40 years. But although being a fix-it junky in this throwaway society do urge everyone to be extra careful; not only fixing them but also using them and having children and pets around where they are operating. BTW as a cruel experiment put a wasp (large fly etc.) or other deemed undesirable insect in a microwave in a glass jar; switch on and it will die in seconds! Note: Radio amateurs can transmit around the world using 150 watts; one sixth the output of a microwave oven and if one thinks of say a 1000 watt electric fry pan or electric hot plate ................... well you wouldn't put your hands or head close to that; would you? Or rather like putting 10 100 watt light bulbs inside a box and then wondering why things got hot!!!!!
