That's pretty groovy. If you Google the guy's callsign, the first hit will
be his website: http://paillard.claude.free.fr/
I clicked the "Translate this page" link, and was able to read some of the
plethora of text. It didn't help me with the French subtitles in the video,
though!

At last!. I had been looking for vacuum tubes homebrewing for ages.
Very good job. Of course, having all the needed tools does help!. Does
anybody know about vacuum pumps homebrewing??? :-)

A simple "column of mercury" (the metal) can pull the necessary vacuum,
you can also run pumps in series--for this application--most likely
would be cheaper to buy the supply of mercury and set up a column to
pull the vacuum for you.

Does anybody know about vacuum pumps homebrewing??? :-)

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!)

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 ...

The guy is a mad scientist... The video is a real hoot to watch... It
is interesting all the jigs and tools he has/made... I wonder if he
bought some of it as surplus from a commercial tube factory, maybe
circa 1920's..
I would have liked to have seen a bit more on the details of the
gettering and filament activation...

So, there ya go guys: it is only a small step from that little triode
to making your own 3CX15000A7 in the basement...

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.

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.

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.

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.

Where Can I get the UNPLUG add on? Is it add on for Firefox
or for the Flash Player plugin? I finally found the file, but all
attempts to "Unlock" the file shuts the SWF player down, even using
special unlocking software.

Anyway, can you spell out exactly how I get this add on and install it
in Firefox?



The file is stored in Windows in the following file/directory:

C;\Documents and Settings\Joe User\Local Settings\Temp\fla_B.tmp
where the _ is A,B,C,D,C. depending on how many times you download
the thing. Any attempts to copy are fruitless, any attempts to unlock
the file are fruitless, as the SWF pugin player just shuts down
immediately and everything disappears. Perhaps there is some software
that can copy the file even though it is locked? I have UNLOCKER
installed on my machine and as soon as I tell it to unlock the file,
it disappears as does the SWF player (flvplayer.swf comes up in
Mozilla when you click on the link).

In meantime I'll try to find this UNPLUG plugin at Mozilla.

Dear Nate;

Thanks, found the UNPLUG at Mozilla site, installed it, and it worked
just fine, now have the file on hard drive to share with friends.
Outstanding film, and thanks to you fellows for helping me find
a way to get it on the computer.

I use NS7.2 (Mozilla Gecko engine); I don't know the filesystem layout
of Mozilla-branded browsers so anyone with details, please chime in.
In Netscape, you can specify cache locations which can permit working
with file and directory permissions independently of volatile temp.
directories such as you have mentioned above. I have not had any
file locking problems with cache files in Netscape when copying
them from a command prompt (I don't work in a GUI). One caveat which
I mentioned before is to allocate sufficient cache size to permit
storing the full flv file and to clear the directory prior to viewing
the video in order to ensure that the file is stored and persists in
the cache.

If your Windows environment somehow prevents access to the file when
it is in a cache on a local drive, try assigning your cache to a
network share which may permit grabbing it from a different machine
(for me, I use Netware shares for my browser's cache and it is easy
to grab them from a mounted nfs filesystem on a unix box or even to
undelete them with the Netware 'salvage' utility if they should vanish).

Perhaps you can use an ntfs undelete utility to recover the file from
a local drive if the above methods don't work for you.

Regards,

Michael
