Hackaday Links: April 16, 2017

Guess what’s going on at the end of the month? The Vintage Computer Festival Southeast is happening April 29th and 30th. The event is being held at the Computer Museum of America and is, by all accounts, a really cool show.

Walk into any package sorting facility or Amazon fulfillment center and you’ll find a maze of conveyor belts, slides, and ramps that move boxes from one point to another. Conveyor belts are so last century, so here’s a fleet of robots.

In 2017, the CITES treaty — an international treaty for the protection of endangered species — changed a lot. While the original treaty protected individual species, in 2017, enforcement of this treaty on tropical hardwoods changed to an entire genus. This is a problem when it comes to rosewood; previously only Dalbergia nigra was covered under CITES, now the entire Dalbergia genus is covered. This sucks for guitar makers, but a Dutch guy is making guitars out of newspaper. We’re probably looking at some sort of micarta thing here, but it sounds acceptable.

Where did Apple’s Spinning Beach Ball of Death come from? 1984, or thereabouts. The ubiquitous Apple ‘wait’ cursor is from the first versions of the Macintosh Toolbox, and it has remained mostly unchanged all this time. This is Apple Wait, a demonstration of this first spinny ball of death. It’s a Raspberry Pi connected to an Apple monochrome monitor that just displays a spinny wait logo. Check out the video.

How do you make strips of RGB LEDs turn a corner? Wire, usually. Here are some corner pieces for WS2812B LED strips. It looks very handy if you’re building a gigantic RGB LED matrix.

SHA2017 is an outdoor hacker conference that’s happening this summer. They’re working on a badge, but they need some help. They’re looking for some funding for their ESP32-powered, touch controller, sunlight-readable ePaper badge. If you have a job that likes to sponsor stuff like this, it’s a worthy cause.

[Federico Musto], one of the Arduinos in the Arduino vs. Arduino saga (which finally came to an end last September) may have fabricated his academic record. This news comes from Wired, providing documents from the registrars at MIT and NYU stating [Musto] never attended these institutions. Since this story came out, [Musto] has edited his LinkedIn, listing his only academic credential as a kindergarten in Torino, Italy.

[shininglaser] built a tinnitus machine. What’s a tinnitus machine? It’s a device that, when activated, produces this sound: eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee. [shininglaser] built this tinnitus machine out of a pair of speakers, a cardboard box, a few batteries, and some sort of board with an epoxy-coated blob. We have no idea what the circuit looks like, but you could do this with any normal signal pulsing at around 15-18kHz (address pins on a CPU for bonus nerd cred) or a simple 555 timer.

This is a hackers bar. This bar in Roppongi, Tokyo is, “a place where you can enjoy live programming and business making…. The term ‘hacker’ is applied to someone who possesses top skills and knowledge to provide innovative and quick solutions even to the most difficult tasks.” It appears they have daily events/talks for JavaScript, Python, R, and Swift.

Captain Crunch needs our help. He’s facing some serious surgery, and even if it’s successful, there’s going to be a lot of stuff insurance doesn’t cover.

We can use Libreboot again. A few months ago, the Libreboot project left the GNU project after an issue with an employee at the Free Software Foundation. Hackaday chose not to report on this only because the accusations levied against the FSF were hearsay. I should emphasize this: the only reason we chose not to report on this is because the accusations were hearsay. Now the Libreboot project is under more democratic management and they’re working on the Thinkpad X220, the greatest Thinkpad of all time. Neat.

Here’s a quick and easy tip to get metal fume fever. Build a foundry out of a galvanized trash can! No, don’t worry about that galvanized coating, it’ll burn off. Oh, he’s doing this indoors. What’s carbon monoxide? Why am I sleepy?

Toorcamp registration is open. It’s June 20-24th on Orcas Island, Washington.

Hey, you. The guy still using Mentor Graphics. Yeah, you. Siemens has acquired Mentor Graphics.

CNC knitting machines are incredibly complicated but exceptionally cool. Until now, most CNC knitting machines are actually conversions of commercial machines. Beginning with [Travis Goodspeed] and  [Fabienne Serriere] hack of a knitting machine, [Becky Stern]’s efforts, and the Knitic project, these knitting machines are really just brain transplants of old Brother knitting machines. A few of the folks from the OpenKnit project have been working to change this, and now they’re ready for production. Kniterate is a project on Kickstarter that’s a modern knitting machine, and basically a 2D woolen printer. This is an expensive machine at about $4500, but if you’ve ever seen the inside of one of these knitting machines, you’ll know building one of these things from scratch is challenging.

There was a time when a Macintosh computer could play games. Yes, I know this sounds bizarre, but you could play SimCity 2000, Diablo, and LucasArts adventure games on a machine coming out of Cupertino. [Novaspirit] wanted to relive his childhood, so he set up a Mac OS 7 emulator on a Raspberry Pi. He’s using Minivmac, beginning with an install of OS 7.1, upgrading that to 7.5.3, then upgrading that to 7.5.5. It should be noted the utility of the upgrade to 7.5.5 is questionable — the only real changes from 7.5.3  to 7.5.5 are improved virtual memory support (just change some emulator settings to get around that) and networking support (which is difficult on an emulator). If you’re going to upgrade to 7.5.5, just upgrade to 8.1 instead.

It’s getting warmer in the northern hemisphere, and you know what that means: people building swamp coolers. And you know what that means: people arguing about the thermodynamics of swamp coolers. We love these builds, so if you have a swamp cooler send it on in to the tip line.

The Prusa edition of Slic3r is out. The improvements? It’s not a single core app anymore (!), so slicing is faster. It’s got that neat variable layer slicing. Check out all the features.

It takes at least a week to delete your Facebook account. In the meantime, you can lawyer up and hit the gym. Additionally, we’re not really sure Facebook actually deletes your profile when you disable your account. Robots to the rescue. [anerdev] built a robot to delete all his content from Facebook. It’s a pair of servos with touchpad-sensitive pens. Add an Arduino, and you have a Facebook deleting machine.

PoC||GTFO 14 is now out. It’s a 40 MB PDF that’s also a Nintendo Entertainment System ROM, and a Zip archive. Pastor Laphroaig Screams High Five To The Heavens As The Whole World Goes Under. Download this, but don’t link – host it yourself. Bitrot will be the end of us all.

[Photonicinduction] is back. The guy best known for not starting an electrical fire in his attic has been working through some stuff recently. He got married, went to India, and he’s going to try to blow a five thousand amp fuse. Good on him.

There’s a certain segment of the Internet that believes the Raspberry Pi Zero doesn’t exist. The logic goes something like this: because I can’t buy a Ferrari right now, Ferraris don’t exist. Now there’s a new and improved website that checks if the Pi Zero and Pi Zero W are in stock: thepilocator.com. It checks a dozen or so online stores for the Pi Zero and Pi Zero W. Guess what? They’re mostly in stock.

[bxcounter] built a PC case and holy crap this thing is incredible. This case is made out of Paulownia wood, and is made up out of fifty pieces held together with magnets. This thing is hand-carved and looks fantastic. Inside is a Mini-ITX motherboard, an i3, a Gigabyte ITX-sized 1060, and an SSD. It’s no powerhouse, but then again it’s not overkill, either. This is a fantastic addition to any battlestation.

As most hackerspaces do, the Omaha Maker Group had a storage problem. Previously, members used plastic totes someone picked up as surplus, but these totes were in short supply. Banker’s Boxes are a better idea, but how to store them? A box case. This ‘bookcase for boxes’ holds 21 standard Banker’s Boxes and only uses two full sheets of MDF in its construction.

This is from the Daily Fail, but a working Apple I is going up on the auction block. It’s expected to bring in $317,693 USD. In other news, we’re going to be at the Vintage Computer Festival East at the end of the month. There is usually an Apple I there.

The most popular crowdfunding campaign of the month is Lego tape. It’s an adhesive-backed tape with studs on the top, allowing you to clip Lego pieces into place. How easy would this be to create at home? It’s really just a silicon mold and some 3M stickytape. Anyone up for a home casting challenge?

You guys know the Hackaday Overlords have a Design Lab, right? What’s a Design Lab? It’s a place filled with tools where we allow residents to come in for free, build stuff, give them training, and let them keep all their IP. It’s like a hardware accelerator, but focused on Open Source hardware. It is our gift to the community and we ask nothing in return. But that’s not important right now. We’re doing shots.

2017 will be the first year Maker Faire will have three flagship faires. New York is a given, as is the Bay Area. and A few weeks ago, Chicago grabbed the third flagship faire. If you’ve already bought tickets and scheduled your trip, terrible news: the Chicago Maker Faire has been postponed until late fall.

Flip clocks are cool. What’s a flip clock? The clock in Groundhog Day, or a bunch of flaps, gears, and a synchronous motor that displays the time. You know what’s not cool about flip clocks? They’re usually stuffed in horrible 70s plastic enclosures painted Harvest Gold or Avacado. [bentanme] found a flip clock and stuffed it in a glass jar. It’s kept in place by a few 3D printed parts that ingeniously keep the clock from moving around while still allowing you to see the gears. Neat.

The world’s first public installation of a solar roadway caught fire or something.

Hey hardware nerds in the UK! Nottingham is having its first monthly hardware meetup. This get together is being put together by [Spencer], creator of the extremely popular RC2014 Homebrew Z80 computer kit. The meetup is free, and it’s happening this Tuesday.

[danjovic] sent in a link to this YouTube channel of a guy building stuff out of PVC sheets and CA glue. There’s a lot of stuff in here from a PVC tripod to instructions on how to get PVC sheets out of PVC pipe. Small warning: this is PVC, and it will kill you instantly, for reasons we can’t yet determine. Additionally, he’s heating PVC, which means cancer for your yet-unborn great-grandchildren. How it both kills you while still allowing you to breed is beyond our comprehension. That’s how bad PVC really is.

NASA has updated their available software catalog. If you want to go to Saturn, you first have to go to Venus three times. Here’s a tool that packs batteries. You should build a router for the interplanetary Internet.

[jlbrian7] is Breaking Android over on Hackaday.io

Last week, we had a Raspberry Pi Hack Chat with [Roger Thornton], the principal hardware engineer at Raspberry Pi. We talked about the hardware that goes into the Raspberry Pi (and the new Pi Zero W), and gave away a few Pi Zero Ws to a few people on hackaday.io that had great ideas for a project. One of the winners of a free Raspberry Pi Zero W was [arsenijs] for his Raspberry Pi Project. This is a really great project that uses a Raspberry Pi and Raspberry Pi accessories. It’s pushing the envelope of what a Pi can be, and a free Raspberry Pi Zero W couldn’t have gone to a more worthy project.

What are you doing the weekend of March 31st? We’re going to New Jersey for the Vintage Computer Festival East. This is one of the better cons we go to. Maybe this year we’ll organize a trip to the pinball museum in Asbury Park.

Statistically, more celebrities died in 2016 than would be expected. 2017 is turning out to be a little better, but we did recently lose the great [Bill Paxton]. Game over, man. Game over. A few years ago, [Benheck] built his own pinball machine. It’s Bill Paxton Pinball. A great build, and worth revisiting, just like another viewing of Aliens and Apollo 13.

Some of the most popular 3D-printable objects are [flowalistik]’s low-poly Pokemon series. They’re great models, even though he missed the most obvious Pokemon. Of [flowalistik]’s low-poly Pokemon models, the Bulbasaur is a crowd favorite. Because this model is constructed from flat planes joined at an angle, it’s possible to make a huge low-poly Bulbasaur on a laser cutter or a CNC router. Go home Bulbasaur, you’re drunk. We are eagerly awaiting details on how this grass and poison-type tank was made.

For the last few months, [Matthew Cremona] has been building a huge bandsaw mill in his backyard. It’s built for cutting logs into lumber, and this thing is massive. He’s been posting build log videos for the last few months, but this week he’s finally gotten to where we want him to be: he’s cutting gigantic logs. In the coming weeks, he’s going to be cutting a maple crotch that’s 60 inches (1.5 meters) across.

It’s still a bit early, but here are the details for the 2017 Open Hardware Summit. It’s October 5th in Downtown Denver. If you want to speak at OHS, here you go. If you want to sponsor OHS, here you go. Tickets are over on Eventbrite.

What happens when you give away a new Raspberry Pi Zero W to the fifth caller? This. In other news, Adafruit somehow acquired a real New York City payphone. I’ve heard they were replacing these with WiFi hotspots, which means there are a ton of payphones in a warehouse somewhere? Can anyone hook us up?
