23. Awesome! I sometimes find it hard to believe what one skilled & determined man and a shop full of powertools can do. He is a real master at work!
Very nice find, thank you hack a day...

24. Yeah, that was cool, but if I hear the first 60 seconds of "The Man I Love" on piano more than 20 times, I go insane and kill the closest bystander. Good thing the video ended at 17 minutes. That was a close one!

25. "also, what kind of setup is required for cutting glass with a wire like that?" - atrain
I've seen something like that done. Basically, you just get a power supply capable of putting out some amps, and hook up a thick enough wire to it (you could probably pilfer it from a toaster -- I think we used piano wire). Wrap the wire around the glass (making sure not to have the two ends touch, which would short circuit your short circuit!) and hit the power. The glass cracks due to thermal expansion. If needed, you can squirt some liquid (like alcohol) around the joint, which will cool off the glass quickly, causing it to break.
26. unbelievable. I just loved some old school manufacturing that i saw around his workshop. Proof that you can do awesome things with a little inovation :)

27. Ok, now we need someone to go and make about 17,000 of these and build their own ENIAC.

28. @25: And high-current, low voltage power supplies aren't actually all that exotic. A soldering gun is one, for example -- it's actually a step-down transformer. The U-shaped piece of metal tubing the tip fits into forms a very thick one-turn secondary winding.

29. (...)
his first article for radio-ref (in 1959) is a bfo for the bc453 "command set" that attract attention for their remarkable selectivity.
he became the editor of "analyses de revues" (analysis of reviews), a column he held several years. he will be also a member of the board of the ref for 3 years.
he publishes, among other things: a linear amplifier equipped with 811, a oscillographic device allowing continuous monitoring of the modulation quality and also of the emitted signal purity, a tv camera equipped with integrated circuits and several ssb ("blu") equipments including a transistorized transceiver which will be widely used in mobile.

30. The dude's got patients.

31. Wow! He made a light bulb? Man life was hard for on indicator lights before LED's. All that just so he could see that his radio was on? In my opinion the sounds is enough :/

Hahahaha sorry couldn't help it.

32. Actualy I think he did use mercury, advance the movie to
15:24 I think thats what he is vaporizing, if im correct that is mercury dripping, I think he is attempting to make Mercury vapor with that machine, probably through decompression, but dont quote me on that one. Im assuming thats how he made the tube following. and why it glows like that. if any one else has specifics please correct me, Im merely commenting on observations.

33. Glad I'm not the only one who felt a deep respect for this guy once I saw his workshop and skills
Now my dream is to be like him in the future... but with transistors :-D
I wonder how hard would be to make an almost-hand-made transistor..

34. @33 (dioxide)
It would consist of a rusty razor blade and a pencil to make a contact diode you could then make this into a contact transistor relatively easily.

36. I think it's especially cool that he's even injection molding the little blue bases himself too!

37. in one word - genius.
In a few short days Hackaday has shown us everything from modding new hardware, someone pushing the edge of car aerodynamics and now this master!
2008 is going to be a great year if you can keep this up!

38. He's probably a retired engineer..

39. Instructables website (Instructables.com) has a home brew Arc welder made with two microwave oven transformers - he home brewed the secondary transformer windings with wire laying around.
Seems things may be more simple than we think.
I mention this because of the Idea of creating the necessary tools to cut glass and spotweld. High amps low volts - :-)
I would also love to try to make a Homebrew spotwelder

40. then, this is the realization of a 2300 mhz station and after of a 10 ghz equipment whose descriptions appear in radio-ref. these both realizations are crowned (with success) in the field by "france-england premieres" in 1968 and 1969. a superb "cross-band" 2.3-10 ghz qso over a distance of 40 km (24.85 miles) is still in memory of the sacred good times of the signatories!
lover and respectful of the old and venerable components, he revives reception tubes of 20s in making emitting it 3 watts on the band 80 m in telegraphy. qso across europe will be realized ... see chapter qrp transmitter.
his reverence for the sir arthur collins's equipment, lead him to restore a number of collins radios, and especially the 618-t.
and then, is it to participate in its own way to the centennial of the invention of the triode by lee de forest in 1906, he launch on the manufacture of the mythical tm developed by the general ferrié in 1915. making a lamp, it's not so easy, but to getting things complicated with difficulty, f2fo will make everything he needs for this project, and especially various pumps, and a molecular one, to get vacuum allowing employment in emission of the made tubes.
a dozen lamps will thus see the light of day ...
to check the measurements, a qso will be realized on january 1, 2005 on 80m in cw between montrouge, 92 and camaret, 29. the tubes are robust and will comme on contacts ...
the original purpose, which was to cross the atlantic, was reched by f6bwo who has realize numerous qso on 4 continents.
the work
the work -- amply illustrated -- is composed of the following chapters:
tubes: history of vacuum tubes, from their emergence in 1906 until the advent of the transistor in 1960
qrp transmitter: realization of a transmitter using lamps from before 1925
triodes: making of a tm triode and necessary tools (pumps, oven ...).
photos: some photos of making steps
mr mignet (pdf: 58 pages - 2 mb): original document describing the making of the "3-electrode vacuum tubes" by a pioneer in the twenties
additions of 6 october 2005 (not reproduced in pdf format)
review after one year of made triodes use (published in megahertz magazine #281 - august 2006)
