> "I found them!" you might say to yourself. But who are you telling? I don't, personally, have this internal monologue. My interior world is a roiling foam of images, feelings and…

As Morse speeds up, you stop relying on individual dots and dashes and begin recognizing common combinations of letters. Faster still and you are mainly hearing word stems and suff…

Yes, it is real time, but due to interrupts you have to manage critical sections with cli() and sei() and your time base is a 16.000 MHz crystal. Most instructions for ATmega and A…

Missing from Open-World Survival Sandboxes: Astroneer. Incidentally some of the best sound design and music I have ever heard in a video game.

Amateur radio is a series of narrow regulatory carve-outs of the radio spectrum for the public good, somewhat like a national park. It has existed since the discovery of radio itse…

Judging by amateur radio subreddits, there is significant crossover interest in this among the prepper and mutual aid community. Rhetorically speaking, what does one do with the fo…

My fear would be Helium and rightwing extremist groups. Currently happy to have the encrypted P25 users on the wrong side of part 97.

A stacked Yagi array. Seriously!

It's not to trim the BOM, it's because electric vehicles emit copious amounts of interference. It is easier to drop AM radio than suppress the RFI. https://www.nytimes.com/2022/12/…

I empathize especially with the author's account of "covid nose." For me, Coca Cola now tastes like patchouli. When I say that out loud, it's easier for others to believe I'm simpl…

I believe you're thinking of the ISM bands - problematic chunks of the spectrum that are given over to industrial, scientific and medical technologies that emit RF by design. The F…

The silver particles in the film aren't very transparent and you can see this for yourself with a microscope. All tonal representations of B&W film, whether a scan or traditional e…

That's a fair question. The time slots I called out above are occupied by learners in the CWops academy. The density of transmissions can be so high that the waterfall resemble the…

And if you want to hear what morse telegraphy sounds like in 2022, you're in luck because it's still alive and well. Simply tune your shortwave radio to 7.028-7.045 or 14.028-14.04…

I worked on a project once involving divination from texts and wrote Terry about this topic. Here's what he told me (2015): """The easiest way to pick a random passage is to read t…

I share your concerns. I created a dedicated-purpose Microsoft account by following Mojang's official migration link. The process went smoothly and I have not been asked for a phon…

Three extraordinary examples from the earlier days of the internet. taxi1010.com. A veteran taxi driver (?) organizes his thoughts around "verbal self defense," creating a highly c…

Background noise - that's one way to put it! The path loss is around 250 dB, so a practical amateur moonbounce station makes use of a very powerful RF amplifier feeding an array of…

LinuxCNC will ( http://linuxcnc.org/docs/2.8/html/gcode/g-code.html#gcode:g2... ) - but your CAM may not. Edit: did not realize I was replying to solvespace, bring on the arcs!

In a way you are describing state of the art robotic arms, but computer vision in that domain is less about economizing and more about coping with everyday materials and objects th…
