places,

Please reference my previous post on this topic; clear your cache
before viewing the video (and be sure to use the url that I posted,
not that crazy Italian url), and then look for a file of the
exact size I stated in the post. Be sure to specify at least
60MB for your cache, or the file won't be there.

Regards,

Michael

A LONG time ago (maybe 40 years?), Scientific American carried an article
(in "The Amateur Scientist" pages) about making a vaccuum pump. (It may
have been part of or near an article about making your own laser which
was strong enough to bounce signals off the moon!)

You can get a reprint of this book from Lindsay books

Or, go to www.surplusshed.com and do a search on "CD". They have
copies of Scientific American's "The Amateur Scientist on CD-ROM"
collection in the Miscellaneous category (item M2071).

"From the archives of Scientific American Magazine, more than 72 years
of experiments and projects from all The Amateur Astronomer, The
Amateur Telescope Maker, and The Amateur Scientist columns from the
beginning in 1928 thru 2001. Every article is complete with all
photos, sketches, etc. More than 1,000 projects in every major field
of science.

"This comprehensive package also includes over 2,000 pages of helpful
Technical Notes that never appeared in the magazine covering topics
from choosing binoculars for astronomy to monitoring earthquakes, as
well as the full text of Procedures in Experimental Physics by John
Strong, a classic and much sought after reference on instrument making."

List price $40, being closed out for $24. I bought one a few years
ago shortly after it came it... it's an impressive collection of
experiments and ideas. Some of them are censored dangerous,
others as safe as milk.

SA's decision to shut down the Amateur Scientist column was a
disappointing one, I think.

If you drive along any levee road in my area, you can remove any number
of units from dumped refrigs' you like, just carry a crescent wrench or
two in your back pocket.

Best thing? Cost $0.00.

Immediate satisfaction too ...

$ locate Cache | grep mozilla

Mind the CaPiTAlIZatIoN there.

Also, insure you have your browser set to actually _use_ cache and
that you have your cache size set Mucho Grande! The video is 57+ MB.

$ ls -ol *.flv

(You'll want to rename it to something human-understandable getting it
out of cache.)

Very good job. Of course, having all the needed tools does help!. Does
anybody know about vacuum pumps homebrewing??? :-)

If you wish to go the vacuum pump route, an old refrigerator unit can
pull a vacuum. I would think you would need at least two in series
with a small tank (reservoir) in between the pumps ...

I was thinking, a couple of air conditioning compressors off autos would
make a heavy duty vacuum pump.

At one time I was thinking of finding a vacuum pump and bell jar to make
a chamber for the vacuum depositing of aluminum on glass for making
telescope mirrors. You need a two stage pump because a GOOD vacuum is
required to make a hard coating on the glass. Such chambers usually
first clean the glass with an ion bombardment using an electron gun
assembly or high voltage discharge.

Get the Unplug add-on, then you can snag all sorts of media files.

I finally got around to watching it last night. Quite impressive. After
all, DeForest et.al. developed these methods when such techniques were
unknown and more primitive. What he shows is that things can be done on
a small scale and don't require large factories or armies of workers.
Also, techniques like those he shows need to be preserved from being lost
to industrial archives.

Beyond the electrical knowledge to make a tube that works, his ability to
work with glass was most impressive to me.

Just where would I type these things:


$ locate Cache | grep mozilla



and


$ ls -ol *.flv
-rw-rw-r-- 1 jonesy 57195626 Jan 3 20:18 HomeMadeVacuumTubes.flv


Do you type it in some kind of SEARCH program or just where please?

I now have the file in the cache, but can't find the cache. I don't
think it's in the Mozilla directory, probably under Documents.
I cleared the cache after setting it to 100 Mb, then downloaded the
file. Still looking, will try a search on *.FLV and see if it
appears.
