    A Call For Humor!

    Names of towns? Back when you got maps at the gas station, I had one where they split that name into two parts to make it "fit".

    Soaring

    There's a light crosswind from the right, I want to align the fuselage parallel with the runway. So the "yaw string" will be blown off to the left a bit. --- To align the string would require a crab to the right, more right rudder. But I'd still need to straighten up before touchdown, and...

    Soaring

    15 miles - It's remaining within gliding distance of the airport. Gliding distance being a calculated ability to reach the airport at a safe altitude without catching any lift along the way, with some fudge factor in case you get into some strong sink. I set my "safety altitude" at 2000 feet...

    Soaring

    Last day of the 2024 Seniors Contest at Seminole Lake Gliderport. Looks like they had a turnpoint up by Ocala. You get more points if you go past the turnpoint. This is an image from FlightRadar24 filtered for gliders. Here's one glider track so far. The North/South track distance is about...

    Opening up a small boutique HiFi shop in retirement?

    Except for the main speakers (bought in 1998), it all came from internet stores and eBay (used stuff) and Amazon and the junk box from work (retired in 2002).. I'd wager the last time I was in an actual Audio Store the calendar started with a 19. Oh, wait, the TV came from Sam's Club, saw one...

    Starlink is very good

    A new(ish) worry to worry about if you're a worrier: "To date, most modeling of reentering space junk has focused on whether any pieces will endure to threaten bystanders on the ground, says Daniel Murphy, the study’s lead author and a research chemist at NOAA’s Chemical Sciences Laboratory in...

    A list of Radio Asytonomy Frequencies http://www.astrosurf.com/luxorion/radioastronomy-lines.htm http://www.astrosurf.com/luxorion/radioastronomy-lines2.htm I wonder how much variation there is due to distant red-shift.

    Post pictures of anything, with comment...couple words.

    No plans, just wishful thinking. If you want to buy a new one, put down a deposit and wait a couple of years for it to be built and shipped from Europe or South Africa. Most being built now include either a sustainer (keep you up) or self-launching electric or gas engine. I doubt there are any...

    I went to drool over the $250k gliders... Mine cost me $12k and is 44 years old. Its performance is maybe 60~70% of the top gear. I didn't see any "for sale" signs. Lots of motorhomes dragging glider trailers from all over the country. Met Sylvia Grandstaff at the back of the line, in the...

    Circuit breaker - which to choose

    My little Krells emit an interesting transformer noise for a second or two from a cold start. If both start at the same time, they have popped the breaker, so I don't do that. Each monoblock rated 350/700/1400W for 8/4/2 ohms, on a single 15A breaker, (along with the rest of the stuff in the...

    How much Watt amplification for 4 Ohm speaker at 65 DB SPL?

    Maybe this... https://sengpielaudio.com/calculator-spl.htm Or this, for up to 30 sources https://sengpielaudio.com/calculator-spl30.htm For eleven sources of +3dB it give a 13.39dB total SPL increase, for incoherent (not identical, as with music) souces.

    Is this the most embarrassing thing you could be caught doing in front of a webcam on the internet?

    If all they are changing is an intermediate ethernet switch there would be no level changes.

    If it takes that long, I can't commit the necessary time to formulate a fully informed opinon.

    Circuit breaker - which to choose

    What PSU? Oh. This, I guess: "Transformer inrush current is the instantaneous current drawn by the primary winding of the transformer when the transformer is initially energized with the secondary side left open-circuited (no load). The inrush current also referred to as magnetizing inrush...
