The hornets DID return this summer! My daughter found their nest today in a new tree. I’ve been walking under this branch all summer, oblivious to the fact that a hornets’ nest was only 18” above my head! I need to figure out how to preserve the nest this winter. Anyone know how?

My teenager is on day 7 of 11 of his backpacking trek in the Sangre de Cristo mountains in New Mexico with his Scout troop at Philmont. I got a single “all is well” message with this photo on Wednesday. It looks like a fantastic adventure and I can’t wait to hear the stories! 😊

‘End of an era’: The last RadioShack in Maryland is closing its doors - Maryland Matters
Before the 2000s, RadioShack was the place to go if you needed a cable or help with anything tech related. Now, the last brick-and-mortar store in Maryland is closing its doors after more than 40 years.

My internet stopped working today. I power-cycled the cable modem, but it didn’t work and I noticed a periodic high pitch whine coming from the modem. I tried a different power supply, and the problem was fixed. Curious, I put the scope on the bad supply. Whoa, that’s not right for 12V DC!!

The hike to the Annaly Tide Pools on St. Croix is fantastic. We were there when tide was rising but it’s so amazing we didn’t want to leave, even if we had to wade back through the surf.

I found the Very Long Baseline Array (VLBA) radio telescope on St. Croix! I have been wanting to see all of these sites since I saw the VLA in Socorro, New Mexico in 2002 and the VLBA telescope on Mauna Kea, Hawaii in 2008.

I did it! This old hot tub may survive the Minnesota winter after all! It has held temperature for 12 hours without the dreaded OHH error. I replaced a pump, slice valve and PVC section, the heater, and the heater relays on the control board.

It hit 45°F today, so I pulled the hot tub control board out for repair. Man, this board had a really bad day at some point, and it’s amazing it was still working. I’ve got the two new heater relays soldered in. I am worried about the power connections, though. We’ll see tomorrow if it works or not.

Heads up, everyone! It appears that 3M has a deal going on where you get a free 11th floppy disk when you buy a new box of 10! #Commodore64

Who needs KP2 on satellite? 🏝️ 🛰️ I’m traveling there February 9 through 12. If I can remember how to use my radios, I’m going to bounce some RF off the birds. #amsat

It’s been almost 3 months and I’m still in awe of having seen the maestro David Gilmour on his #LuckAndStrangeTour in Los Angeles. The show was indescribably amazing. I didn’t want the night to end. Thank you @gilmourtour.bsky.social and my wife for the best Christmas gift ever!

Long time listeners know my evangelical tendencies regarding Vise-Grips pliers (not to mention zip ties). Look at these two little guys that are travel-sized for all occasions! The curved jaw set is 4.5 inches long, the long nose 5.25 inches.

This summer in the Boundary Waters, I actually found the lake in XKCD #1024! If you want to go sit by this lake yourself, it’s at 48.1685, -91.53. 😁 #BWCA

My son was practicing classic for his high school Nordic ski team tonight, so I had to figure out how to use his skate skis this time. I like that there’s a real rhythm to both types of cross-country skiing, and if you get into the groove then you can just GO! ❄️

I got a print of my daughter’s (4th grade) artwork for my office. With a makeshift frame, it not only covers the electrical panel but also adds beauty to my new space.

My friend Eric helped me install a drop ceiling in my new home office / mad scientist laboratory. The main project is nearly done at this point!
