Running a Hackerspace is Hard: Egypt Edition

It’s no secret that it’s difficult to run a hackerspace. Different personalities, different material requirements, and often constrained spaces can require continual negotiation. But if you think that having the metalworking types getting their shavings on your electronics bench is a problem, try having your entire hackerspace demolished on short notice.

The situation in Cairo is far from normal at the moment. The building that Cairo Hackerspace had recently moved to was raided, closed for two months, and then re-opened under strict surveillance in February.

All was well until a part of the building unexpectedly collapsed. Then they got a demolition order, followed by postponement, followed by armed police entering anyway and breaking stuff, followed by a further declaration of the building as safe, and now a heritage site. And all of this over a week’s time. While some of the art studios in the Townhouse were saved, the Cairo Hackerspace’s space is gone.

The good news? Nobody got hurt in all of this, and the Cairo Hackerspace crew were able to get their gear out after the initial demolition notice. They’ve been working on a mobile hackerspace-in-a-van approach lately, so hopefully they’ll be able to keep on hacking.

So when you’re bickering over who didn’t clean up the hackspace’s coffee machine, or the proper location of your favorite soldering iron, think kindly about the Cairo crew and get back to doing what you do best — projects.

Hyperloops and Robot Cars, A Glimpse into The Future

His mobile blooped at him with one of those noises a company spent money to get. A timer started on the screen as he rushed to put his shoes on. He finished and pushed open his door, running down the stairs two to a bound. By the time he reached the bottom of the stairs he had his backpack slung over both shoulders, which he mentally cursed himself for since he’d just have to take the dang thing off again.

It was morning on January first, and he was due at his parent’s house for a new year’s dinner fifteen hundred miles away. He should have booked a plane weeks ago, but now the Loop was his only option. The Loop didn’t really have peak rates, and while the plane would be a little faster, more direct, and cheaper IF he had remembered to book it in time, the Loop would take him the same distance today. Plus, the seats were comfier. They reclined nicely, and he intended to nap on the way. Hopefully, by the time he got there, the bleariness from last night’s celebration would be undetectable by parental senses.

He locked the door to his apartment complex, a reassuringly square assembly from the seventies, and walked to the sidewalk where a friendly light blue car waited for him. When he got close, his mobile vibrated and made another distressingly cheery noise. The doors of the car swung open opposite of each other to expose the space inside. The car displayed two rows of inward facing bench seats, a panoramic row of windows around the entire perimeter of the vehicle, and… yes, his nose was telling him before his eyes fixed on it, a very unsettling amount of vomit in the center of the floor.

He turned around, a bit squeamish, and took out his mobile. He navigated through the controls. Where is the menu option? What year is it now? Why is this still hard? Three awkward menus deep and he finally found and selected the option to let the dispatch know the car had an issue which made it uninhabitable. The car immediately began to chirp warnings and the doors soon started to close. In a moment, a human somewhere in the city would be looking at a video of the inside of the car, determining him a liar or not. As expected, a few seconds later, the little car began to drive off. The lights on the rear of the car turned from bright red to the yellow amber of headlights as it decided its front would be its back. It drove off to the dispatch center for cleaning and repair. Someone would be eating a 100 dollar cleaning bill today. He didn’t feel sorry for them.

His phone began to vibrate. He picked it up to answer a call from a bored customer service representative who was trying hard to sound earnest. “Sorry for the trouble sir, the ride today will be free. We have another car on its way”

Makerbot Has Now Cut 36% of Staff in Last 6 Months

The CEO of Makerbot, [Jonathan Jaglom] announced this week a massive reorganization. Twenty percent of the staff will be laid off, management will be changed, an office will be closed, and perhaps most interestingly, the production of 4th generation of Makerbots will be outsourced to contract manufacturers.

This news comes just months after Makerbot announced its first 20% reduction in staff, and follows on the heels of a class action suit from investors. These are troubling times for Makerbot.

So Goes Makerbot, So Goes The Industry

In the last six months, Makerbot has closed all three of its retail locations in Manhattan, Boston, and Greenwich, CT. It has moved out of one of its office buildings in Industry City, Brooklyn as the company faces a class action suit from investors for possible securities violations. These are by any measure troubling times for anyone at Makerbot.

The 3D printing industry has been forced through the rollercoaster of the hype cycle in the last few years, and where Makerbot goes, media coverage and public perception of 3D printing goes with it. According to pundits, we are now deep in the doldrums of the trough of disillusionment. No one wants to make their own parts for their washing machine, it is said, and 3D printers are finicky devices with limited utility.

Despite these pundits’ projections, the 3D printing industry doubled in 2015. Multiple manufacturers of sub $5000 machines are going gangbusters, and seeing the biggest revenues in the history of their respective companies. By any measure except the one provided by Makerbot, we are still in an era of a vast proliferation of 3D printing.

Makerbot, for better or worse, is a bellweather, and public perception and media attention is highly dependant on the success of Makerbot. The Verge writes – incorrectly – “…The consumer 3D-printing market’s rise has slowed”, and Business Insider writes ‘consumers are beginning to lose interest.’ These are not statements backed up by facts or statistics or even hearsay; they are merely a reflection of the consumer’s disinterest in Makerbot and not of the 3D printing industry of the whole.

Unfortunately, we will not know the extent of how bad it is at Makerbot until Stratasys releases its 2015 financial report sometime in early March next year. Wohlers Report 2016, the definitive guide to the 3D printing industry, will be released sometime around May of next year. Keep one thing in mind: Makerbot did not build the 3D printing industry, and the public perception of Makerbot does not necessarily translate to the public perception of 3D printing.

The Alexanderson Transmitter: Very-low Frequency Radio Rides Again!

Is your ham radio rig made of iron and steel? Is it mechanically driven? Classified as a World Heritage Site? We didn’t think so. But if you’d like to tune in one that is, or if you’re just a ham radio geek in need of a bizarre challenge, don’t miss Alexanderson Day 2015 tomorrow, Sunday, June 28th

The Alexanderson Transmitter design dates back to around 1910, before any of the newfangled tube technology had been invented. Weighing in at around 50 tons, the monster powering the Varberg Radio Station is essentially a high-speed alternator — a generator that puts out 17.2 kHz instead of the 50-60 Hz  that the electric companies give us today.

Most of the challenge in receiving the Alexanderson transmitter broadcasts are due to this very low broadcast frequency; your antenna is not long enough. If you’re in Europe, it’s a lot easier because the station, SAQ, is located in Sweden. But given that the original purpose of these behemoths was transcontinental Morse code transmission, it only seems sporting to try to pick it up in the USA. East Coasters are well situated to give it a shot.

And of course, there’s an app for that. The original SAQrx VLF Receiver and the extended version both use your computer’s sound card and FFTs to extract the probably weak signal from the noise.

We scouted around the net for an antenna design and didn’t come up with anything more concrete than “few hundred turns of wire in a coil” plugged into the mic input.  If anyone has an optimized antenna design for this frequency, post up in the comments?

Thanks [Martin] for the tip!

Hackaday Links: June 14, 2015

You know we’re running this gigantic contest to build hardware and send someone to space, right? We’re doing community voting right now. If you’re on Hackaday.io, head over there and pick the best project. We’re giving away t-shirts and $1000 gift cards to people who vote. The drawing for this round is next Friday.

MicroPython is a pretty interesting development in the area of interpreted languages running on microcontrollers. It’s Python, the BASIC of the modern era, and now it’s being funded by the ESA. Great news, there’s going to be a port to SPARC, and it looks like MicroPython is going to be in a few satellites.

[EloquentlyMawkishBunny]’s calculator stopped working on the morning of his AP Physics test. It was the ribbon cable for the display. What did he do? He grabbed some magnet wire and made it work. If I’m reading this right, he did this the day of his AP test. Wow.

[Will] has made a name for himself by building roller coasters in his backyard. He’s also worked on the ProtoPalette, and now he’s building a hackerspace in Concord, California.

[Josh] needed to drill some very large holes with his mill. He decided a hole saw was the easiest way to do this, but his hole saw has a hex shank. He ended up chopping the shank of a hole saw extension, basically turning it into a hex to round adapter.

Did you know the Arduino IDE on Raspbian is stuck at version 1.0.5? The newest version is 1.6.4, and there’s useful stuff like autosave in the IDE now. Amazing. [CRImier] got the latest Arduino IDE working on the Raspberry Pi 2. Yes, there’s an issue up but if for some reason you’re programming Arduinos on the Pi, you should probably do this yourself.

Oooohhhh, case modding. The Intel NUC is a pretty interesting platform for case modding; it’s small, and I shouldn’t have to remind anyone of all the cool case mods that were created when the Mini-ITX format gained popularity in the early ‘aughts. [Femke] got herself an Intel NUC, made a case, and the results are amazing. How’d she get that metal bowl? Metal spinning. Very cool.

Circuit Love With Multicolor Solder Masks

The cheapest PCBs – and therefore most common – are green solder mask with white silkscreen. It works, but it’s also incredibly boring. This is the way things were done up until a few years ago with the explosion of board houses trying to compete for your Yuan, and now getting a red, yellow, black, blue, green, and even OSH purple is possible. This doesn’t mean multiple solder masks aren’t possible, as [Saar] demonstrates with his demonstration of multicolor solder masks and circuit love.

We’ve seen a lot of [Saar]’s designs, including a mixing desk, a cordwood puzzle, and an engineer’s emergency business card, but so far his artistic pieces have been decidedly monochromatic. For this build, [Saar] teamed up with Eurocircuits to create a board that exploits their capabilities.

Althought Eurocircuits has PCB PIXture, a tool for putting graphics on PCBs, [Saar] made this with his own tool, PCBmodE.  The design of both the red and yellow variants are abstract, and only meant to be a demonstration of what can be done with multicolor solder mask. It looks great with five backlit LEDs, and with an acrylic top and bottom, makes a great coaster or art piece.

We like [Saar’s] work so much that we put his Cordwood puzzle in the Hackaday Store.

“Superfan” Gaming Peripheral Lets You Feel Your Speed

Virtual reality has come a long way but some senses are still neglected. Until Smell-O-Vision happens, the next step might be feeling the wind in your hair. Perhaps dad racing a sportbike or kids giggling on a rollercoaster. Not as hard to build as you might think, you probably have the parts already.

HAD - Superfan4Off-the-shelf devices serve up the seeing and hearing part of your imaginary environment, but they stop there. [Jared] wanted to take the immersion farther by being able to feel the speed, which meant building his own high power wind generator and tying it into the VR system. The failed crowdfunding effort of the “Petal” meant that something new would have to be constructed. Obviously, to move air without actually going on a rollercoaster requires a motor controller and some fans. Powerful fans.

A proponent of going big or going home, [Jared] picked up a pair of fans and modified them so heavily that they will launch themselves off of the table if not anchored down. Who overdrives fans so hard they need custom heatsinks for the motors? He does. He admits he went overboard and sensibly way overbudget for most people but he built it for himself and does not care.
