Blackberry REACT April 2009 NewsletterQuick ClicksICS forms onlineThis site has over 40 ICS forms in MS Word format for download. There are several versions of many of the forms. Iron-on patchesWhen I was a kid, our jeans always had patches, mostly on the knees. Everybody’s did. In honor of the coming depression, I post this link to iron-on patches so modern folks can see how to handle worn-out clothes. After-action report: Silver Dragon IIII’ve posted an after-action report at the Blackberry REACT Facebook site. If you have any comments or questions, feel free to post them. If you are not a Blackberry REACT Facebook member, email me, and I’ll send you an invitation. Punks not DadSome geezers have done up a punk song called “In Me Shed” (they’re British, so they talk like that) extolling the glorious virtues of locking themselves in their garden shed to varnish picture frames, sorting out me jam jars, repotting me tomatoes, and so on. All in three loud chords on the guitars and one note on vocals. If you’ve ever had a family and needed a moments peace, you’ll feel right at home in me shed. 50 Years of Boeing badnessActually, not that kind of badness. This is a photo of a B-17 and a B-52 flying in formation near Barksdale AFB. Fifty years of bombers by Boeing. The B-17 is beautifully restored, so it’s worth clicking the photo for the screen-filling large view and gazing at all the details. (I can’t figure out where the author came up with fifty years.) CraigsList sale of vacuum tubesBecause this may disappear, I’m copying the entire text here for your reading pleasure: Hi i have 8 7591 vacuum tubes that were new old stock, i tested these in a scott amplifier and worked well. I carefully removed the glass on each tube to clean both sides as all the tops had silver inside blocking view of tubes light now the tubes have no glass but may still work. asking 50.00 each. Photographs of the glassless vacuum(less) tubes are at that link. Electrons on ParadeA 1942 film (this is part 1 of 2) by RCA that shows in great detail how vacuum tubes were made. The amount of hand labor is staggering, even though they used machines for a great deal of the construction. Apparently, RCA created the metal and forged and drew their own wire! The link to part 2 is on the right of the page. It’s a total of 20 minutes, and I watched the whole thing. There’s a brief overview of how the tubes work, with film of the anode, cathode, and grid, with animation showing the electrons, err, on parade. Hand micrometers are in frequent use, and they actually tap each completed tube with a little mallet before testing to see what breaks. At the end we get the stirring music while the voice over tells us of all the manifold uses of vacuum tubes, including the heroic hams in time of calamity. Why security dogs are not a problem
