I'm normally pretty good about writing close to length, but the first draft of this 950-word article was over 2,000 words long. :) I only get three pages per issue though, so even though sometimes it's painful deciding what lore t

You should check out the Media Archeology Lab, they are very interested in alternate networks of all types! https://www.mediaarchaeologylab.com/

Original article author here: Yes, key pages were multiple times over teletext. It's a bit of a grey area for amateur radio regs, so I didn't mention it in the article, but you could use the software with say, an license-free par

Original article author here: There's isn't anything on the wider web about this project because it is a bespoke creation for IEEE Spectrum's Hands On column! If you're not familiar with the column, it's always writ

Author of the OP article here: Yes, you could 100% send teletext frames over meshtastic: if you're using the unlicensed bands you could even send full carousels with many pages, which is something that isn't really kosher under my

You have me pegged correctly :)

Thank you, I'm glad you agree they are nice! The artist is James Provost, he's done most of the illustrations for Hands On since we switched over from photography a few years ago (I'm the IEEE Spectrum editor responsible for

You're in luck! David Schneider, the author of this piece, also built a $150 hydrogen line antenna for us, based on a TV tuner SDR: https://spectrum.ieee.org/track-the-movement-of-the-milky-wa... :)

I'm the editor of Spectrum's "Hands On" DIY column: thank you so much! The general goal is to have projects that can be done in a weekend or three for less than roughly $300 and which point to something interesting beyon

The back end we use for article infographics on the Spectrum website is from a company called Flourish, so anything that looks like it's from them is actually editorial content. We used to roll our own Javascript for the Top Programmin

There's an embedded interactive chart at the very top of text: have you blocked embeds from running?

Ugh, should be fixed. Another transfer problem that always has to be catched manually. I've been putting articles online since the mid-1990s, and in 30 fecking years of watching ever more elaborate text processing, DTP, web and content

Congrats on being an early reader, b/c I spotted this on a fresh read Monday morning and zapped it! [I'm a IEEE Spectrum editor] This is a problem that's got me the odd time before—when you've read an article so many tim

For reals, we thought about putting one in, although the blobs and spires would have been the payload in the center of a solar sail, but we couldn't squeeze it in! [I'm an IEEE Spectrum editor :) ]

If you are doing passive radar, then a UHF/VHF TV antenna should cover you for whatever digital channel you choose

Thanks! I have notes scattered around, but they're not coherent (unlike the RTLs! <rimshot>) and I doubt I'll have time to publish them as once I've written an article I generally have to move on the next thing, which i

Yes, the United States has a you-can-recieve-anything philosophy (with some limits for old analog cellphone frequencies, and restrictions on using, e.g. a police scanner in a car) that isn't matched in many other countries, which is th

Sorry if I didn't make this clearer in the article due to space constraints, but the TV surveillance antenna gives me a fair degree of directionality, enough to distinguish planes on different LGA and JFK approach/departures paths

One other crazy detail I didn't have space to put in the article is that half of the driver chips are mounted upside down in cutouts in the circuit board! It's so the data bus and some other control signals can be daisy chained be

The low memory was another impetus for upgrading it. I use a REX chip upgrade, which gives me a lot more storage, but the RAM can only hold an article's worth of words at a time, anything longer and you're having to save and loa

That's why I was so motivated to keep it! (I'm the author of the article!)

The only issue with the 102 is that it uses surface mount components throughout, while in the 100 they are only in the display module, which makes 100's easier to repair, but YMMV.

It's nice that the Tandy's haven't seen the kind of price escalation that's affected other computers of the same vintage, especially compared their original price!

We have an accompanying article that goes into that in more detail here: https://spectrum.ieee.org/the-rise-of-sql I've added a link in the TPL article to make it easier to find.

Okay, to be technical, we get the raw values for each metric: say the number of job ad that mention language X, or the number of Google search results. Then, using R/R Studio, we normalize the the raw values so they range from 0 to 100

That's what I thought happened too: that I had slipped by one combining the descriptions with the numerical data, but it turns out that the first five were permuted when I looked in the data for the presentation engine! Don't quit
