Charlie's Angels

Image
Charlie's Angels was a show that probably everyone watched at least once but might not want to admit it.  Kate Jackson was my favorite :) I remember them like this: But I kinda wish I hadn't seen this: But consider the fact that Kate Jackson is 77, Jaclyn Smith is 80 and Cheryl Ladd is 74.  They've got nothing to apologize for. Also, don't want to forget Farrah Fawcett-Majors (who would have been 79 now):   as Roger Ebert liked to say, the girl with the great . . . TEETH  :) BTW, this is why I never attend any school reunions, I remember those people as they were: young and slim and strong - with lots of plans and ideas for the future.

Foot Power

Image
Here is a really cool video: source:  https://www.youtube.com/watch?v=G5WJUFvKzWk Go back 100 years => movies were still silent.  This one does have sound but no narration although it does have notes on the process (sorta like title cards in silent movies) - turn on CC to see them. This fellow is the silent screen version of Roy Underhill from PBS :) update 2026-05-12:  forgot their site:   https://trampverkstan.se/     Use some form of translation unless you've recently brushed up on your Swedish !  This video also reminds me of G5BD who has been mentioned before: https://wb9kzy.blogspot.com/2024/05/saw-gil-cartoon-in-qst.html also see:  http://wb9kzy.com/g5bd.htm Can you say: Foot Mangle ?  :) Here's another G5BD page with a 1928 QSL mentioning foot powered: https://hamgallery.com/qsl/country/England/g5bd.htm And of course our Glen Gates Gang Field Day natural power efforts (the armstrong method was used rather than foot power): the lash...

Inchfab

Image
This is really clever: https://spectrum.ieee.org/inchfab They don't mention packaging or for that matter, test.  But the concept of smaller wafers implying smaller equipment never occurred to me.  The IC fab machines that ASML makes are handling wafers which are at least 300 mm (think of something the size of an LP record).  Inchfab is using 100 mm wafers (smaller than a DVD). I remember one of the test engineers at GTE talking about when he worked at Teletype in Skokie, IL.  He mentioned that they had a 2 inch wafer fab there which really impressed me - I never knew that there were semiconductor fabs in the Chicago area.  The later Teletypes (like the model 43 ?) must have used these chips.  Think of a keyboard with a printer: I also recall him saying that Teletype worked on a 10-30 process.  Once they got to 10% yield they went into production, when they reached 30% yield it was time to advance to a newer design.  And sometimes they'd come back ...

Saturday Miscellany

Image
Went tramping through the woods, looking for ramps when I came upon this scene: Not sure how old it is but those appear to be turkey feathers.  I see their tracks in the snow during the winter. Someday I will have to try a wildlife cam - a good way to use batteries AND a good excuse to get exercise tramping out in the woods after the ramps are done. Lucky Strike Extra:  I went to the store yesterday and bought a dozen large eggs:  $1.39 - last weeks price $3.09. payment info blanked out just because I could :) So eggs are less than 1/2 price this week ! Is the Wisco curse over ? Maybe only partially, left fielder Lockridge hurt himself badly (bone visible, yikes !) running into a low wall: The Brewers gotta do something about that padding on the wall ! Oh yeah, the Miz had a good night, the 5 fastest pitches thrown by a starter: Best Regards, Chuck, WB9KZY http://wb9kzy.com/ham.htm

A Show About Nothing - the originator

Image
source: https://www.youtube.com/watch?v=sXYWZhN8Yks But the original maker of a show about nothing was Yasujiro Ozu - that's probably not totally fair but not much action in an Ozu movie - no swords or guns or horses - lots of silences though :) Previous Ozu post:   https://wb9kzy.blogspot.com/2023/06/ozu-was-right-at-least-in-my-case.html Here is what prompts this post: source:  https://www.youtube.com/watch?v=s5P22nEmF3k As mentioned before, Good Morning is probably the most accessible of the Ozu movies - kids gotta move ! Every Frame a Painting is an amazing Youtube channel, mentioned it before: https://wb9kzy.blogspot.com/2024/10/every-frame-painting-is-back-kinda.html Hopefully TCM and Every Frame a Painting will team up on more videos in the future.  Best Regards, Chuck, WB9KZY http://wb9kzy.com/ham.htm

Robotic Familiar ?

Image
Interesting article in IEEE Spectrum : https://spectrum.ieee.org/familiar-machines-and-magic It's not a pet or a friend, it's a robotic familiar ?  The first thing I thought of was Jiminy Cricket - but this robotic familiar is trying to help humans become better rather than trying to turn a puppet into a real boy :) Here's the company site:  https://www.familiarmachines.com/ I dunno, seems like a mechanical pet or artificial friend to me.  And with real pets or friends you feel bad when they die.  This thing will eventually die.  I've heard that the Sony Aibo, the robotic dog, was beloved by it's owners and now that Sony doesn't support it anymore, they feel bereft when nothing more can be done.   They were called Artificial Friend (AF) in this book:  https://en.wikipedia.org/wiki/Klara_and_the_Sun I shudder to think what kinds of short videos will be made by teens for social media - the poor familiar !

Schottky Diodes

Image
I took a second look at measuring the leakage current of the Renogy solar panel - that first reading of ZERO current kinda bugged me. https://wb9kzy.blogspot.com/2026/05/the-renogy-solar-panel-dischargeleakage.html   I used the newer Triplett DVM just in case there was some kind of problem with the Metex used before.   At 12.84 volts I again measured zero current in any of the three ranges. So I was thinking about that and this is my surmise: there are lower voltage Schottky diodes like the 1n5818, 1 A diode I used on the other solar panel.  The low voltage diodes have somewhat high leakage currents.  Then there are higher voltage Schottky diodes for use in switching supplies and the like.  They have higher forward voltages but smaller leakage currents.  Here is part of a Nexperia Schottky diode data sheet: I will have to pay the tariff tax and get some of these How does this fit in with the Renogy solar panel ?  The Renogy has 72 solar cells which I a...
