Commercial Items Identified on my Commute

-

I see a lot of interesting commercialitems on truck on I-75. When you make the commute many times you start to see the same items over and over again. Sometimes it is huge equipment tires, sometimes heavy equipment of different types. I see these huge blocks of aluminum going North. I think about what the mill must look like and where it is going. And how much aluminum foil a block like this will make. Using the Tesla Full Self-Driving (supervised) allows me to look for these things on the highway. The FSD also helps me through the crazy stop and goes. Easily over 70MPH and then sudden traffic at dead stops, frequently. I see accidents every trip. It is amazing there aren't more. A side note- aluminum foil has a shiny side and a dull side. The reason why is that the foil is folded as it goes through massive rollers. The shiny side is the side that faces the steel roller. The dull side faces itself - aluminum.

I guess I cant stop buying radio equipment. I found a good deal on a few pieces of test equipment I didn't have. I had to buy them. I bought an IFR FM/AM-1200S service monitor. It is a classic. It is mostly pre digital. I consider this unit to be an "argument breaker" as far as determining what exactly is happening on frequency. It is very good at determining sources of interference and it has practically every bit of test equipment in one package. And it is battery powered. I also bought a Rigol DG1022 Function/arbitrary waveform generator, a BIRD watt meter/dummy load and a variable transformer. The only regret is that the Variable transformer is not the isolating type. I will have to figure out if I can make it isolated. It is an important piece of test equipment for old vacuum tube radios.

Ditches, Vents and Drains

Beautiful morning on the lake. I needed to put some vents in the basement. It's never about just one thing. The vents through the brick was one thing. Getting a window well to allow proper airflow and a drain to ensure the window well doesn't fill with water are other things. I had some fun with my bobcat and digging in the dirt. I am glad its over. We went out to dinner at the American Legion Post in the neighborhood. It only made sense to drive my M998 and pose next to the tank. The humvee has been my grocery-getter lately.

Knives and Septic Systems

I went to the largest knife show anywhere. It was in Atlanta. https://bladeshow.com/home/ It's not like I am crazy about knives. I am however, interested in intense human efforts and world class passion in particular areas. I find myself having very involved discussions with folks that are sharing their passion and expertise. I met with folks about knife making from the US and Western Europe of course, but also South Africa, Finland, Australia. It's a effective and pleasant way to learn. I had an issue (sewer pipe was broken by my stump grinder) with the septic system here in Duluth. Of course, I had to ask lots of questions and do inspections and assessments myself. Septic technology is interesting. Nothing to be scared about and although the technology is ancient and sometimes unplesant there is a lot to know. https://extension.uga.edu/publications/detail.html?number=B1421&title=a-beginners-guide-to-septic-systems Having that knowledge is especially important if you...

The Electromagnetic Spectrum --DC to Daylight (and actually well beyond)

Besides carrying my scintillation detector with me looking for ionizing radiation (over 2.46 petahertz) and decaying isotopes, I have been playing in the more friendly "basement" of the electromagnetic spectrum (under a gigahertz). A pic of my radio bench. I sold my IFR ( http://blog.theguysatwork.com/2025/02/updates-storm-and-other.html) . I needed to replace the function (at least a lot of it) with a cheaper digital produt. So for 1/10 the sale price of my IFR, I ended up buying a TinySA Ultra+ ZS406 Spectrum Analyzer. It is indeed tiny. It does what I want it to do and it's a fun new toy. Our autographed copy of the "Fall of Civilizations" arrived from the UK. Paul Cooper does such a great job with his pobcasts and videos. I felt compelled to get a personalized copy of the book. ( https://www.paulmmcooper.com/ ) Seeing this licence plate on the front of a pickup truck seemed fitting-- not so much as contrarian, but as a Komatsu equipment fan. It's g...
