A Crummy Commercial

I remembered that my 8th grade English teacher, Miss McGrath, would read aloud to us from the book: H*Y*M*A*N K*A*P*L*A*N .  So I did a little searching and found out that Leo Rosten (pen name: Leonard Q. Ross) started publishing the Kaplan stories in the New Yorker Magazine. I fired up my copy of The Complete New Yorker and quickly found the Rosten stories:    In a way they are perfect as separate short stories since the 1930s were a different time with plenty of unfortunate stereotypes and language usage.  So a little taste goes a long way. But I also saw this ad (the New Yorker used to be able to sell a LOT more ads than they do today): Interesting in that this was a compact set made to run from 6 volts and probably included either an RF stage or an extra IF amp to boost the gain.  Plugging the price into the inflation calculator: Wow, that is a LOT of money today and considering that the Depression was still an ongoing thing, yikes, I wonder how it sold ?...

This seems interesting: source:  https://spectrum.ieee.org/electric-salt-spoon-and-cup But the price: source:  https://www.ebay.com/itm/306611168384 The only electric spoon I own: slide the black switch and press the red button and a red LED would light up the clear spoon has lost the ability to light up :(  It was a Kellogg's premium.  I never figured out how to get at the battery.

Saw this: Immediately wondered about the semi-obligatory inflated price: And because it is almost 2026, I am thinking of raising my postage charge on kit orders to $6 per order from the present $5, as someone would have said in the 1960s: "rats" Best Regards, Chuck, WB9KZY http://wb9kzy.com/ham.htm 

Continuing from yesterdays blog: https://wb9kzy.blogspot.com/2025/12/short-circuits.html   Here is a simple, fun, discrete component AM Morse Code Transmitter from the Short Circuits volume 1, page 30: The circuit shows .1 uF audio timing caps for the flip flop but I changed them to .22 uF which  lowered the frequency to about 660 Hz: I can't remember where I got the ferrite antenna but it was the only one I had with 4 leads:      After hooking up the last transistor I got these waveforms at about 480 kHz: damped carrier about 6 div x .25 ms per div = 1.5 ms period or about 670 Hz damped carrier, 4.2 divisions x 500 us per division = 2.1 us period or about 476 kHz The bell shaped decay - is this similar to how a spark waveform would have looked ?  Anyway a functional simple circuit, worth trying but it needs work.  It is lower in frequency due to the scope probe capacitance as well as the solderless breadboard capacitance. The Short Circuits volume 1 c...

I saw these Jaycar (an Australian electronics seller) electronics books for beginners mentioned on the GQRP list (page down to the bottom): https://www.jaycar.com.au/short-circuits The idea is relatively simple and fun circuits that are easy to construct and understand.  The first volume has discrete circuits assembled on a solderless setup.  The later books have solder projects with circuit boards and parts kits sold by Jaycar.  For example this FM radio caught my eye: But then I looked for the TDA7000 and found that while it could be found on Ebay it is discontinued.  The prices on the TDA7000 chips that are available are high, probably would be cheaper to just get an old FM radio that used the TDA7000 ?  Here is a really interesting blog post on the TDA7000: https://www.righto.com/2025/08/reverse-engineering-analog-TDA7000.html BTW the blogger, Ken Shirriff, is one of the cast of the Curious Marc videos on Youtube !  Here is his traced out schematic for ...

It didn't really turn out that well: I still had 4 quarts of canned maple sap that I never drank (was going to use it for iced tea or lemonade or ?) so the decision was made to do a final boil to maple syrup.  Except that I forgot to measure the sugar concentration before starting.  So I stopped too early and got maybe twice the volume (7 oz) that I should have. It's sweet and will work OK to sweeten coffee or tea but a little too watery for pancakes. Best Regards, Chuck, WB9KZY http://wb9kzy.com/ham.htm 

I do try to do computer backups on Saturday, mainly of this blog.  Today after the backup I checked and found this: Quite a gap from October 11 to December 13.  What am I doing wrong ?  I'm not sure.  But today I was signed into Archive, hopefully that will help.  I clicked the link at the bottom of the weekly listing of blog posts and then backed that weeks worth of blogs up.  In that way I was able to save all the posts in the gap (I think).  Luckily I have a pretty high threshold for boredom - it was 9 weeks worth of blogs. So a backup is worthless unless verified, especially with a somewhat slap-happy entity like archive :( update 2025-12-14: signing in didn't help, the Wayback dumped my backup attempt yesterday:    I will try a nastygram or maybe turn off the VPN ? Weird ! Best Regards, Chuck, WB9KZY http://wb9kzy.com/ham.htm
