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?

A Goldmine Of Radio Shack Goodies Is Up For Auction

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.

Quick question: what was the first personal computer? We love pointless arguments over technological history, so let’s just go down the list. It wasn’t an IBM, and the guy who invented the personal computer said he didn’t invent the personal computer. The Apple I is right out, and there were some weird Italian things that don’t quite count. Here’s an auction for, “The first personal computer”, a MICRAL N, released in 1974. There’s an 8080 running at 500kHz with 16kB of RAM and ‘mixed memory’. This is an important bit of history that belongs in a museum, and the auction will start at €20,000. The starting price might be a bit high; recently an original Apple I sold at auction for €90,000. This is a pittance for what these things usually go for. Is the market for vintage retrocomputers dropping out from underneath us? Only time will tell.

In Upstate NY? There’s a Hacker con going on June 16-17. You can get 20% off your ticket to ANYCon by using the code ‘HACKADAY’.

Colorblind? Hackaday readers suffer from colorblindness at a higher rate than the general population. [João] created this really neat tool to differentiate colors on a screen. Windows only, but still handy.

Everyone’s excited about the $150 3D printer that will be released by Monoprice sometime this summer. Here’s a $99 3D printer. Yes, it’s a Kickstarter so the standard warnings apply, but this bot does have a few things going for it. It uses actual NEMA 17 motors, and the people behind this printer actually have experience in manufacturing hardware. The downsides? It’s entirely leadscrew driven, so it’s going to be very, very slow.

What do you call the dumbest person with an EE degree? An engineer. It’s at this point where you should realize the value of a tertiary education is not defined by the most capable graduates; it’s defined by the least capable graduates.

Here’s your Sunday evening viewing: [Bunnie] gave a talk on RISC-V and the expectations of Open Hardware.

Hey, OpenBuilds has a new Mini Mill. It’s a basic CNC router designed for small ~1HP Bosch or Dewalt laminate trimmers. Small, but capable.

Kerbal Space Program, the only video game that should be required study materials at the Air Force Academy, Embry-Riddle and for everyone working at NASA, has been acquired by Take-Two Interactive. By all accounts, this is good news. According to reports, the original dev team left for Valve a few months ago, reportedly because of terrible conditions at Squad, the (former) developer of KSP.

The Stratolaunch carrier aircraft has rolled out of the hangar. It’s two 747s duct speed taped together.

Penny auction hacking; put on your statistician’s hat

Penny auctions are where you must pay a fee each time you bid. Certainly this alters the behavior of the bidders, but there doesn’t seem to be a lot of info about exactly how. In preparation for an analytics degree, [Jay] decided to study penny auctions and see if he can win a contest based on his findings. Now he’s not necessarily looking to make a living by gaming the auction system. But we were interested to see how he went about getting information, and what he has to say about the results.

Since there really isn’t a large body of data available, he scraped it himself. You’ll want to page through his posts on the topic, but basically he’s using Python on a fast machine. This is made quite a bit easier through the use of Selenium RC, but it also means he’s got a lot of instances of Firefox running to track multiple auctions. Scraped data is stored in CSV files, and posted to his front page daily.

From what he’s captured so far [Jay] suggests that time of day, type of auction, and several other factors dictate when you should bid to attain the best deals.

Grizzly suit up for auction

Do you have a burning desire to fight grizzly bears? If you do, We can’t guarantee that the first bear you face will win, but we really can’t imagine another outcome unless you use [Troy Hurtubise]’s Mk IV suit, which is currently up for auction. We have discussed the suit before along with several other high-tech power suits, but this is the only one with bear-resistance in mind. The suit features several safety features, including layers of chainmail and titanium.The suit was also featured in the film “Project Grizzly.” [Hurtubise] is hoping to sell the suit for $40,000 or more to offset his personal costs, and judging by the current price, he may well make it.
