If the great Samuel Clemens were alive today, he might modify the famous meteorological quip often attributed to him to read, “Everyone complains about weather forecasts, but I can’t for the life of me see why!” In his day, weather forecasting was as much guesswork as anything else, reading the clouds and the winds to see what was likely to happen in the next few hours, and being wrong as often as right. Telegraphy and better instrumentation made forecasting more scientific and improved accuracy steadily over the decades, to the point where we now enjoy 10-day forecasts that are at least good for planning purposes and three-day outlooks that are right about 90% of the time.
What made this increase in accuracy possible is supercomputers running sophisticated weather modeling software. But models are only as good as the raw data that they use as input, and increasingly that data comes from on high. A constellation of satellites with extremely sensitive sensors watches the planet, detecting changes in winds and water vapor in near real-time. But if the people tasked with running these systems are to be believed, the quality of that data faces a mortal threat from an unlikely foe: the rollout of 5G cellular networks.

If you think Apple products are overpriced now, wait until they’re 50 years old.
This original Apple I recently sold at auction for $375,000, making it one of the most expensive 6502-based computers in history. Given that only something like 60 or 70 of the machines
were ever made are known to exist, most built by hand by [Jobs] and [Wozniak], it’s understandable how collectors fought for the right to run the price up from the minimum starting bid of $50,000. And this one was particularly collectible. According to the prospectus, this machine had few owners, the most recent of whom stated that he attended a meeting of the legendary Homebrew Computer Club to see what all the fuss was. He bought it second-hand from a coworker for $300, fiddled with it a bit, and stashed it in a closet. A few years later, after the Apple ][ became a huge phenomenon, he tried to sell the machine to [Woz] for $10,000. [Woz] didn’t bite, and as a result, the owner realized a 125,000% return on his original investment, before inflation.
The machine was restored before hitting the auction block, although details of what was done were not shared. But it couldn’t have been much since none of the previous owners had even used the prototyping area that was so thoughtfully provided on the top edge of the board. It was sold with period-correct peripherals including a somewhat janky black-and-white security monitor, an original cassette tape interface, and a homebrew power supply. Sadly, there’s no word who bought the machine – it was an anonymous purchase.
Hackers, check your scrap bins. Anything hanging out there that might be worth six figures in a few decades? It’s unlikely, but if you get lucky, hacking just might turn into your retirement plan.
Thanks to [my wife] for the tip on this one.
It may not be the typical fare that we like to feature, but you can’t say this one isn’t a hack. It’s a camp trailer fashioned from the back half of a wrecked Honda Civic, and it’s a pretty unique project.
We don’t know about other parts of the world, but a common “rural American engineering” project is to turn the bed and rear axle of an old pickup truck into a trailer. [monickingbird]’s hacked Civic is similar to these builds, but with much more refinement. Taking advantage of the intact and already appointed passenger compartment of a 1997 Civic that had a really bad day, [monickingbird] started by lopping off as much of the front end as possible. Front fenders, the engine, transmission, and the remains of the front suspension and axle all fell victim to grinder, drill, and air chisel. Once everything in front of the firewall was amputated, the problem of making the trailer safely towable was tackled. Unlike the aforementioned pickup trailers, the Civic lacks a separate frame, so [monickingbird] had to devise a way to persuade the original unibody frame members to accept his custom trailer tongue assembly. Once roadworthy, the aesthetics were tackled — replacing the original interior with a sleeping area, installing electrics and sound, and a nice paint job. Other drivers may think the towing vehicle is being seriously tailgated, but it seems like a comfy and classy way to camp.
Now that the trailer is on the road, what to do with all those spare Civic parts? Sure, there’s eBay, but how about a nice PC case featuring a dashboard gauge cluster?
The name Cray, as in [Seymour Cray] is synonymous with supercomputing. If you hurry, you can bid on a Cray J90/J916 on eBay. You might want to think about where to put it though. It is mounted on a trailer, requires 480V, and the shipping is $3,000!
First introduced in 1994, the J90 was an “entry level” machine. This particular machine supported up to 16 CPUs (each CPU was actually two chips) running at a blazing 100 MHz. The memory system was more impressive, achieving 48 GB/s.
The Cray T90 computer was much faster (and more expensive) but none of these computers had the performance of a typical PC’s graphics card these days. Even your phone may have more raw computing power, depending on how you choose to measure. Don’t fear, though. Cray Research still makes supercomputers that can eat your phone for lunch.
Still, at the time, this was big iron. The I/O system used SPARC processors that would have been entire workstations in that era. The eBay listing says it might need a little work — we weren’t clear if the seller meant in general or just the cooling system, but you can assume this is a fixer-upper. Apparently, the Retro-Computing Society of Rhode Island restored a similar beast so it can be done.
If your holiday budget doesn’t have room for a real supercomputer, here’s one that is 1/10 the size and much less expensive. Or, you could just pretend.
Ok, we’ll stipulate it right up front: this isn’t a hack. But you have to admit, it would make a fine starting point for a truly epic one. Robby the Robot — the robot from the 1956 movie Forbidden Planet is up for sale. Well, technically he isn’t so much a robot as he is a suit with some animatronics. The auction lot includes Robby, his (non-functioning) vehicle, a control panel, and some other accouterments. If you have deep pockets, you’ll need to bid before November 21.
MGM reportedly spent $125,000 on Robby which was a crazy amount of money in the 1950s. In today’s currency, that would be well over a million bucks. They got their money’s worth, though, as Robby appeared in movies and TV shows including Lost in Space and several episodes of the Twilight Zone. He even made a motionless cameo on The Big Bang Theory.

We found the most boring man on the Internet! HTTP Status Code 418 — “I’m a teapot” — was introduced as an April Fools Joke in 1998. Everyone had a good laugh, and some frameworks even implemented it. Now, the most boring man on the Internet and chairman of the IETF HTTP working group is trying to get 418 removed from Node and Go. There is an argument to removing code 418 from pieces of software — it gums up the works, and given only 100 code points for a client error, with 30 of them already used, we don’t really have space for a joke. There’s a solution, though: someone has submitted a request to register 418 as ‘I’m a teapot’.
The Travelling Hacker box is a migratory box of random electronic junk. The box has traveled across the United States several times, and earlier this year it started across Canada — from Vancouver to St. Johns — to begin an International journey. The box is now missing, and I’m out. I’m turning this one over to the community. There are now several rogue boxes traveling the world, the first of which was sent from [Sophi] to [jlbrian7] and is now in Latvia with [Arsenijs]. The idea of the Travelling Hacker Box is now up to you — organize your own, and share random electronic crap.
Bluetooth 5 is here, or at least the spec is. It has longer range, more bandwidth, and advertising extensions.
Guess what’s on the review desk? The Monoprice Mini Delta! If you have any questions you’d like answered about this tiny, very inexpensive printer, put them in the comments. I only have some first impressions, but so far, it looks like extending the rails (to make a taller printer) is more difficult than it’s worth. That’s not to say it’s impossible, but with the effort required, I could just print another printer.
Interested in PCB art? [Drew] found someone doing halftone art with PCBs. This is a step up from nickels.
Indiana University is getting rid of some very, very cool stuff in a government auction. This device is listed as a ‘gantry’, but that’s certainly not what it is. There have been suggestions that these devices are a flight sim, but that doesn’t sit quite right either. It’s several thousand pounds of metal, with the minimum bid of $2.00 at the time of this writing. Any guesses on what this actually is?
Where did you buy the parts for your first electronic project? That’s a question likely to prompt a misty-eyed orgy of reminiscences from many Hackaday readers, if ever we have heard one. The chances are that if you are from North America or substantial parts of the English-speaking world, you bought them from a store that was part of the Radio Shack empire. These modestly sized stores in your local mall or shopping centre carried a unique mix of consumer electronics, CB radio, computers, and electronic components, and particularly in the days before the World Wide Web were one of very few places in which an experimenter could buy such parts over the counter.
Sadly for fans of retail electronic component shopping, the company behind the Radio Shack stores faltered in the face of its new online competition over later years of the last decade, finally reaching bankruptcy in 2015. Gone are all but a few independently owned stores, and the brand survives as an online electronics retailer.
The glory days of Radio Shack may be long gone, but its remaining parts are still capable of turning up a few surprises. As part of the company’s archives they had retained a huge trove of Radio Shack products and memorabilia, and these have been put up for sale in an online auction.
There is such a range if items for sale that if you are like us you will probably find yourself browsing the listings for quite a while. Some of it is the paraphernalia of a corporate head-office, such as framed artwork, corporate logos, or strangely, portraits of [George W. Bush], but the bulk of the collection will be of more interest. There are catalogues galore from much of the company’s history, items from many of its promotions over the years including its ventures into sporting sponsorship, and numerous examples of Radio Shack products. You will find most of the computers, including a significant number of TRS-80s and accessories, tube-based radios and equipment from the 1950s, as well as cardboard boxes stuffed with more recent Realistic-branded items. There are even a few retail technology dead ends to be found, such as a box of :CueCat barcode readers that they evidently couldn’t give away back in the dotcom boom.
If you are interested in any of the Radio Shack lots, you have until the 3rd of July to snap up your personal piece of retail electronic history. Meanwhile if you are interested in the events that led to this moment, you can read our coverage of the retail chain’s demise.
Thanks [Mark Scott] for the tip.
