The nearby seismic waveforms are interesting regarding this video. The P wave arrives before the S wave and is orders of magnitude smaller. I think that cat is reacting to the P wave. The first P arrived about 7 seconds before the S wave and the cat jumped about 5 seconds before the big shaking
Monet is primarily viewed today as a prominent impressionist. What isn't so well known is that in his later years, he could be seen to be dabbling with surrealism.
Really temperature. I've heard people in Phoenix complain about temperature this high.
Bank of America is trying to make sure their customers can't be part of class action lawsuits ... or much any lawsuits. Happily, consumers can still opt out of these one-sided changes. I have. My guess is that you should as well. #banking #consumers #consumerprotection #classaction
So the boards came back for this and the results were pretty cool. I wanted to make a filter to get high quality signals out of a cheap AD9851 board. Based on feedback from @de6u99er.bsky.social, though, I decided to add a two layer version. Here's an alt-text spoiler. 🧵 #electronics #hamradio
The README describes the function. Here is a projected response with quasi realistic Q. The design methodology was to start with a designed filter with 65MHz cutoff, 0.2 dB ripple and 55dB stop band attenuation. Then I replaced components with what I had handy with simulation in KiCAD.
I just whipped up a design for a better quality anti-aliasing filter for chips like the AD9851. Most cheap boards that have the AD9851 have seriously bad filtering which leaves a very strong signal at the clock frequency (180MHz) and with any aliased signals. This filter should fix that.
Building stuff is sooo much fun. It's almost more fun when it's tiny. Source is at github.com/tdunning/sma... #hamradio #electronics
Just to check that something in the world still works the same, I verified that you can still get into the tardis at Earl's Court station (on Google maps)
I have updated my toy project to make an SMA based oscilloscope probe based on building the first version. Links to the github, to a place you can buy the boards (for <$1 each!) and more below. #hamradio #electronics github.com/tdunning/sma... oshpark.com/shared_proje...
It seems only right that somebody establish a B&B in New Mexico, NSW called Sydney, New South Wales. It would be right up there with the Indiana University of Pennsylvania, Indiana, Pennsylvania.
That complement is the rural place called "New Mexico" which is found in New South Wales (in Australia).
Today, from the annals of Great Marketing Blunders, I present the B&B near Acoma pueblo in New Mexico known as "Sydney, New South Wales". If this place actually exists, it would be completely impossible to find via a Google search. There is an interesting complement to this, however. 🧵
Posole at our house is a little bit late this year. But late is better than not.
I was putting on an ancient Tish hinojosa t-shirt this morning and got a good reminder. Yes, we can. We can cultivate awareness.
Here's a cool way to visualize how progressive lenses work. I printed a 2mm grid and taped it to the wall. Then I used an old fashioned clothes pin and cable ties to mount the glasses in front of the grid about 30-40cm away. Taking a picture focussed on the magnified part of the grid gives this.
I just threw a quick donation at KiCAD. Those guys do some really wonderful work I get a ton of enjoyment out of playing with circuits.
This has since been fixed on their web site, but it seems that the NYT now depends on readers for copyediting their headlines.
