"Must-Have, Survival" Discretes

Hi all,

Some years ago on this group I posed the question, "if you were washed up on a desert island and could take only a suitcase-full of discrete semiconductors with you, what would it comprise?

Many years later, and in the light of supply changes/shortages and whatnot....

Gentlemen, (and Lady (as I am recently informed)) which semiconductors would *you* - TODAY - take with you to some distant, foreign shore, to ensure your survival and contact with what remains of a post- apocalyptic human race?

TNX., Me. (the tall, intelligent, good-looking one who used to post here some time ago).

Phased-plasma rifle, in the 40-watt range.

Oh _today_? Never mind.

About 1000 ft. of hookup wire, a deep-cycle battery, an ignition coil, and a fingernail file. ;-)

Hope This Helps! Rich

They\'d come looking for you, all right, but not to save you. ;)

Toss in a 14V solar panel to keep the thing charged, eh?

Better yet, take one of those army pedal generators in case the sun don't shine. Keeps you in shape as well, remember, there's no gym memberships on desert island.

And don't forget at least one of grandpa's coal-fired solder irons. It would be really sad if whatever charge scheme you used failed, battery is empty, you find the cause but can't solder in a new transistor because there's no juice left.

Wonder how to screw the bolts into sand, to keep it from wobbling... concrete, epoxy, bolts? ;-)

charcoal fired solder iron, then? (not likely to be a whole lot of coal on a desert island)

Toss in a charcoal retort then, to make charcoal?

Say, what would the range be for such a contraption?

Sand, ashes, and urine? ;-)

Oh, yeah - a firestarter. ;-)

Dunno, but Carl & Jerry did it once after a car crash in the boonies. ;-)

Nah, it has to be done the true island way. Take strands from a palm tree, weave a rope from that and use it to tie the generator to tree roots. Then after the first amp-hours has gone into the battery, climb on top of the highest hill and let off a Tarzan yell :-)

Is there electricity on that island?

A different question: suppose you had a time machine and wanted to send volumes of one chosen electronic part back in time, to the US Army, at the start of WWII, to help them win the war sooner. What would that part be?

I'd vote for 2N7000.

I'd vote for the BFP620. Now wait, that's from ...

At the _start_?

A decent magnetron.

"An early 6 kW version, built in England by the GEC Research Laboratories, Wembley, London, was given to the US government in September 1940. It was later described as "the most valuable cargo ever brought to our shores" (see Tizard Mission)."

That was *before* we were officially in the war.

The three key components of microwave radar were the cavity magnetron, the crystal diode mixer, and the klystron, which was developed by the Varian brothers, Russell and Sigurd, here in California.

The history of the klystron is an interesting story in itself.
