Stuff is getting away from me

Image
I tried checking on an online magazine, mentioned before here: https://wb9kzy.blogspot.com/2022/11/that-time-hitlers-girlfriend-visited.html I apparently don't read that site very often: It's been over a year since my last visit ?  Here is the explaining link: https://hakaimagazine.com/article-short/so-long-and-thanks-for-all-the-fish/ And here is a new website done by the same  people: https://www.biographic.com/ The internet loves to change but only seems to get worse.  But Biographic looks like an interesting site with a bigger portfolio than Hakai.   One strange thought: the Littoral Combat Ship USS Milwaukee (some of the LCS ships were built in Wisconsin and tested near the island) also only lasted about a decade: https://wb9kzy.blogspot.com/2023/09/lcs-yikes.html Operating near the shore like the LCS or Hakai must be trickier than people thought !

Crystal Radio is still relevant in the 21st

Image
Yes, I know that there's not much worth listening to on AM radio.  But it's still fun to build a crystal set,  mentioned here: https://wb9kzy.blogspot.com/2022/01/alfred-p-morgan.html I recently saw this Superboy's Workshop Razor Blade Radio which I'd like to try:   Watching this Vertitasium video reminded me of crystal sets: source:  https://www.youtube.com/watch?v=YSJY3DvnybE It showed multiple places where the concept of a bare bones crystal radio (basically a diode and a tuned antenna) was used by the CIA for bugging the Soviets.  It is also used in RFID tags to provide power.  And it is used in credit cards and debit cards to power the chip. One thing they didn't do too well in the video was differentiate between credit cards and debit cards.  About the only place I use a credit card on the island is at Mann's store.  But somewhere I do have some thin sheet metal - might be hard on the wallet though.  I think I will also stop carrying m...

The Price ? Astounding !

Image
I became aware of an adjustable voltage regulator IC, the LM338K, which is a 5 amp adjustable regulator in a TO-3 can: Yikes, over $100 ?   The LM338T is the same part in a TO-220 package: The only reason I can see for offering the part in the expensive package is that the TO-3 steel case is probably hermetically sealed (hermeticity requires metal, glass or ceramic) - this is important in certain commercial and military applications.  I suspect that these are for repair / spares only - although it's surprising that they still offer the chip at all in this package.  The TO-220 packaged chip would be fine for me :) Best Regards, Chuck, WB9KZY http://wb9kzy.com/ham.htm  

Opening Day

source:  https://www.youtube.com/watch?v=g24WKKj0kA4 And the White Sox are already in last place: This game reminded me of a Jean Shepherd story about the White Sox: source:  https://www.youtube.com/watch?v=O2e3Ov1lFyg The Old Man hated Lou Gehrig ?  I shudder to think what he said when The Pride Of The Yankees premiered !  And what would The Old Man have said when Munetaka Murakami (the big money slugger from Japan) hit a 9th inning homer into the 2nd deck in right field for the Sox on opening day 2026 ?  Just like Lou did  :) Lou Gehrig: source:  https://en.wikipedia.org/wiki/Lou_Gehrig Ted Lyons: source:  https://en.wikipedia.org/wiki/Ted_Lyons Zeke "Banana Nose" Bonura: source:  https://en.wikipedia.org/wiki/Zeke_Bonura   Munetaka Murakami:    wiki:  https://en.wikipedia.org/wiki/Munetaka_Murakami   BTW, if any part of Jean's story is untrue I don't want to know it :) update: here is the story on the Shepherd WOR...

Another failed whisper to an AI

Image
This was the input: from the side: kid sitting and soldering at a workbench, plans on wall. in front of him, posters and pennant on wall to his right, open small suitcase on floor with a skunk in it These were the results: This was the original McCloskey drawing from Homer Price: the skunk's name is Aroma, he rides up to Homer's room in that basket Anyway I got 20 Microsoft Rewards points by trying it.

Maple Syrup Update

Image
The new stand is working well - it was mentioned here: https://wb9kzy.blogspot.com/2026/03/new-perch.html Then a couple things happened.  First there was the snow storm so I wasn't able to get any sap to boil.  The second was that I realized something.  I hadn't checked the calibration on the refractometer in a long time.  So I put a little distilled water (sap) on the slide and zeroed the reading. there is an adjustment screw under the round black cap above: ATC I was able to restart the boils after the ski experiment: https://wb9kzy.blogspot.com/2026/03/red-ski-is-for-right-foot.html The last few boil results have been good (ideal brix is 66.7): boil    brix    evaporation in grams (roughly 1 percent) ----    ----    ----  29     66.5     44  30     67       47  31     67       46  32     65...

Henry Reed, Inc.

Image
Henry Reed, Inc. is a kids book from 1958, written by Keith Robertson and illustrated by Robert McCloskey.    https://archive.org/details/henryreedinc00keit The McCloskey drawings are what make the book for me.  Mentioned him previously: https://wb9kzy.blogspot.com/2024/06/homer-price.html I am pretty sure I read Henry Reed, Inc. in the 6th grade.  But maybe it was a similar book - I remember it because we had to do drawings with our book reports and mine was of a runaway balloon that had to be shot down like the one in Henry Reed, Inc. : It's a fun book - I noticed two items that would have passed me by in 1966-67, first sunspots: Since the book was written near the greatest sunspot peak in the radio era but I was just into radio at that point and hadn't known that.  Anyway it must have been the thing to blame everything on sunspots in the late 1950s. The second item was this: I remember hearing Jean Shepherd voice the same opinion so I don't know if it was c...
