Hackaday Links: December 2, 2018

CircuitPython is becoming a thing! CircuitPython was originally developed from MicroPython and ported to various ARM boards by Adafruit. Now, SparkFun is shipping their own CircuitPython board based on the nRF52840, giving this board an ARM Cortex-M4 and a Bluetooth radio.

You like contests, right? You like circuit boards too, right? Hackster.io now has a BadgeLove contest going on to create the Blinkiest Badge on Earth. Yes, this is a #badgelife contest, with the goal of demonstrating how much you can do in a single circuit badge. Prizes include a trip to San Francisco, a badass drone, a skateboard, a t-shirt, or socks. YES, THERE ARE SOCKS.

We have a date for the Vintage Computer Festival Pacific Northwest 2019. It’s going down March 23 and 24 at the Living Computers Museum in Seattle. The call for exhibitors is now open so head over and check it out. So far the tentative list of exhibits and presenters include Attack of the SPARC Clones, and I must mention that SPARC systems are showing up on eBay with much higher frequency lately. I have no idea why.

Need another con? How about a KiCAD con? The inaugural conference for KiCAD users is happening next April in Chicago and the call for talk proposals just opened up. The con focuses on topics like using KiCAD in a manufacturing setting, what’s going on ‘under the hood’ of KiCAD, and how to use KiCAD to make an advanced product.

Spanish police have stopped a homemade scooter. Someone, apparently, was tearing around a public road in Galacia on a homemade scooter. From the single picture, we’re going to say ‘not bad.’ It’s a gas-powered weed wacker mounted to a homemade frame.

Every year, in December, we take a look back at what Hackaday has accomplished in the past twelve months. Sure, we gave out hundreds of thousands of dollars in awards in the Hackaday Prize, and yes, we’ve pushed our coverage of tech advancements into weird, uncharted, but awesome territory. Our biggest accomplishment, though, is always how many readers we reach. This year, we had a slight fall-off in our readership in the Democratic People’s Republic of North Korea. We’re down from 156 views in 2017 to 75 views this year. While the year isn’t over, we don’t expect that number to change much. What was the cause of this drop-off? We’re not quite sure. Only time will tell, and we’re looking forward to serving fresh hacks every day to the DPRK in 2019.

2017’s VCF West is Another Beloved Trip Down Memory Lane

This past weekend, another smashing round of the Vintage Computer Festival was held at the Computer History Museum in Mountainview. As always, VCF West gathers the sages and lords of vintage computers onto a common ground to talk old-school hardware. It also draws in a collection of unique artifacts, many of which either still work, have been brought back to life, or have otherwise been reincarnated through a modern means. [Bil Herd] and I dropped in to join the crowd, and I snagged a few pics of some new faces and pieces that have been added to the experience since last year.

[Foone’s] Digital Media Archiving

Up first on our bucket list was [Foone], a librarian of digital media archiving. Outside of VCF, he runs a digital media backup gig to help folks backup their niche, often-failing, disk formats into something more modern. His drive for doing this backup features a special “reread” capability, where the file is actually reread dozens of time to validate that the right information was pulled from it.

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.

The Best Of VCF East

Last weekend was the Vintage Computer Festival East in Wall, New Jersey. While this yearly gathering of nerds nerding out on old computers might be a bit too obscure for some, there are always amazing exhibits of actual historical importance. A few Enigma machines showed up, and the rarest Commodore goodies made an appearance. We saw the pre-history of Hackaday and ‘maker’ culture with Southwest Technical Products Corporation, and found out it was probably, possible to build a RepRap in the 80s. You can’t know where you’re going unless you know where you came from, and even though the old timers were a bit more grizzled than us the Vintage Computer Festival shows how little things have actually changed.

What was the coolest and weirdest stuff at VCF? What does the Silverball pinball museum look like? Check that out below.

VCF: Popular Electronics And Southwest Technical Products Corporation

Hackaday owes a lot to the hobbyist electronics magazines of yesteryear. Back in the day, Popular Electronics and Radio-Electronics would publish projects and articles about DIY electronics – more or less the same editorial purview we hold today. Some of these projects would become full-fledged products, and you need only look at the Altair for what can happen at this confluence of publishing and engineering.

One of the more popular companies to come out of these hobbyist trade magazines was SWTPC, or Southwest Technical Products Corporation. This was the company that brought one of the first microcomputers to the masses with the SWTPC 6800. This wasn’t just a homebrew microcomputer company – there were Nixie clocks, test gear, and stereo preamplifiers – all things that could easily find a place on the pages of Hackaday today.

This year at the Vintage Computer Festival East, [Michael Holley] brought out the test gear he’s been collecting for the past few decades. These are machines that wouldn’t be out of place on any DIY electronics blog today. This is by all accounts the pre-history of the maker movement.

VCF: 3D Printing In The 80s

The Vintage Computer Festival East is going down right now, and I’m surrounded by the height of technology from the 1970s and 80s. Oddly enough, Hackaday frequently covers another technology from the 80s, although you wouldn’t think of it as such. 3D printing was invented in the late 1980s, and since patents are only around for 20 years, this means 3D printing first became popular back in the 2000’s.

In the 1970s, the first personal computers came out of garages. In the early 2000s, the first 3D printers came out of workshops and hackerspaces. These parallels pose an interesting question – is it possible to build a 1980s-era 3D printer controlled by a contemporary computer? That was the focus of a talk from [Ethan Dicks] of the Columbus Idea Foundry this weekend at the Vintage Computer Festival.

Vintage Computer Festival Switzerland This Weekend

This weekend marks the Vintage Computer Festival Europe – Switzerland, a two-day extravaganza of vintage hardware held in Zurich, Switzerland.

Of interest for this VCF will be an LGP-30 replica (a computer without RAM or ROM released in 1956), an IBM System/360 front panel, lots of blinkenlights, Swiss computers, and [Oscarv], creator of the very successful PiDP-8/I project on Hackaday.io, will be there with his minified PiDP-11/70. If you don’t have one of [Oscar]’s PiDP8 machines sitting on your desk yet, don’t worry — the 11/70 is the one you really want. It is beautiful.

As you would expect from a Vintage Computer Festival, all the standards will be there. The flea market is open, soldering stations are present, talks will be held, and very old and very rare hardware will be blinking. From our experience with Vintage Computer Festivals, Europe does it right. Last year’s festival in Munich was a blast, and this year’s celebration in Zurich looks like it will be as well.
