MAKE: Blog: Make your own vaccum tubes?: "Check out this absolutely mesmerizing (17 minute!) video of a French amateur radio operator who rolls his own vacuum tube triodes! I love the ease with which he performs these rather high-end skills (like glass forming), the gestural flourishes (like it's hand magic), and the Zelig-esque soundtrack"
And O thought the guy in our Ham group was hardcore making his own radio from a kit. This is real hardcore. But it reminds me of a hot dog pushcart vendor from NYC who used to make it look like he was conducting symphony while putting a hotdog together.
