Over the last few years, Maker’s Asylum in Mumbai has grown from a garage to a very well stocked workspace with 140 members. They’re getting kicked out at the end of the month and they need some help. We just had a meetup at the Delhi branch of Maker’s Asylum, and these guys and gals are really cool.

Speaking of crowdfunding campaigns for hackerspaces, South Central Pennsylvania might be getting its own hackerspace. The 717 area code is a vast wasteland when it comes to anything anyone reading Hackaday would consider interesting, despite there being plenty of people who know their way around CNC machines, soldering irons, and welders. This needs to happen.

Need some help with Bluetooth standards? Tektronix has you covered with a gigantic poster of the physical layer. If only there were a repository of these handy, convenient reference posters.

Forgings and castings make for great YouTube videos, and this aluminum bell casting is no exception. There’s about 18 pounds of aluminum in there, which is pretty large as far as home casting goes.

Electronic Goldmine has an assortment of grab bags – spend a few dollars get a bag of chips, LEDs, diodes, or what have you. What’s in these grab bags? [alpha_ninja] found out. There’s some neat stuff in there, except for the ‘SMD Mixture’ bag.

Remember the found case molds for the Commodore 64C that became a Kickstarter? It’s happening again with the Amiga 1200. This is a new mold with a few interesting features that support the amazing amount of upgrades that have come out for this machine over the years. Being new molds, the price per piece is a little high, but that’s your lesson in manufacturing costs for the day.

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.

Hackerspace Happeninging: A Booc For C-Base

In the annals of hackerspace history, there’s one space that stands above the rest. It’s c-base, the crashed spaceship below Berlin that’s also one of the first hackerspaces in the world. Before NYC Resistor, Noisebridge, and every other building filled with tools and cool people, there was c-base.

Although the Hackerspace movement has only been around for a little less than a decade now, c-base itself is much, much older. It was founded way back in 1995, marking this year as the second decade of c-base’s existence. A few of the members of c-base are celebrating this occasion by publishing a book on the vast and storied history of their hackerspace.

The mythology of c-base includes a space station crashing in the middle of Berlin, with the giant, famous disco ball in Berlin being the station’s antenna. Yes, it’s weird, but all good hackerspaces have some sort of irreverent mythos surrounding them. The c-booc will document the twenty year long excavation of the space station, chronicling how this hackerspace came to be.

The booc is a Kickstarter project, and if funded, will be available for pickup at the Chaos Communication Camp this August

Prof Gershenfeld Speaks on Fab Labs and all-things Digital

Fab Labs have developed hand-in-hand with the all-too-familiar hackerspaces that we see today. If you’re curious to discover more about their past and future, [Prof Gershenfeld], founder of the Fab Lab, and director of MIT’s Center for Bits and Atoms brings us a fresh perspective on both these fab labs and the digital world we live in.

In a casual one-hour chat on Edge, [Prof Gershenfeld] dives deeply into the concept of digital in our world. We might consider digital to be a binarized signal, an analog waveform discretized into a 0 and 1 from which all of computer architecture is built upon today. Digital doesn’t just exist in the computing sense, however; it’s a concept that has been applied to communication, computation, and, these days: personal fabrication.

[Prof Gershenfeld’s] talk may highlight coming changes in the future, but changes are already happening today. These days, fab labs and hackerspaces serve their communities in a very special way. They take “experts-of-the-field” away from universities and isolated labs, and they scatter them all over the world. With this shift, anyone can walk through their doors and build a solid foundation in fields like embedded programming and computer aided manufacturing by striking a conversation with these local experts. In a nutshell, both spaces found a culture for development of expertise far more accessible to the world community than their university counterparts.

If you can spare the hour, put on some headphones, tune in, and resume your CAD work, PCB layout, or that Arduino library. You may discover that your work is built on a number of digital principles, and that your contributions push the rest farther along the development chain towards building something awesome.

Finally, if you’re interested in taking notes on building your own fab lab, have a look at the inventorylayout, and guidelines at the CBA website.

Here’s a worthwhile Kickstarter for once: the Prishtina Hackerspace. Yes, that’s a Kickstarter for a hackerspace in Kosovo. Unlike most hackerspace Kickstarters, they’re already mostly funded, with 20 days to go. If we ever get around to doing the Istanbul to Kaliningrad hackerspace tour, we’ll drop by.

Codebender is a web-based tool that allows you to code and program an Arduino. The Chromebook is a web-based laptop that is popular with a few schools. Now you can uses Codebender on a Chromebook. You might need to update your Chromebook to v42, and there’s a slight bug in the USB programmers, but that should be fixed in a month or so.

Here’s a great way to waste five minutes. It’s called agar.io. It’s a multiplayer online game where you’re a cell, you eat dots that are smaller than you, and bigger cells (other players) can eat you. [Morris] found the missing feature: being able to find the IP of a server so you can play with your friends. This feature is now implemented in a browser script. Here’s the repo.

The FAA currently deciding the fate of unmanned aerial vehicles and systems, and we’re going to live with any screwup they make for the next 50 years. It would be nice if all UAV operators, drone pilots, and everyone involved with flying robots could get together and hash out what the ideal rules would be. That’s happening in late July thanks to the Silicon Valley Chapter of AUVSI (Association for Unmanned Vehicle Systems International).

SOLAR ROADWAYS!! Al Jazeera is reporting a project in the Netherlands that puts solar cells in a road. It’s just a bike path, it’s only 70 meters long, and it can support at least 12 tonnes (in the form of a ‘fire brigade truck’). There’s no plans for the truly dumb solar roadways stuff – heating the roads, or having lanes with LEDs. We’re desperately seeking more information on this one.

Trademarking Makerspace

UnternehmerTUMMakerSpaceGmbH, a tech accelerator in Munich, Germany, has just filed an application to trademark the word Makerspace. This has caused some contention in the German-speaking hackosphere, and if this trademark application is approved, the few spaces in Germany that identify as a makerspace may soon be changing the sign out front.

It must be noted this trademark application only covers the word ‘Makerspace’, and not “Hackerspace”. To most of the population, the word ‘hacker’ – in English and German – conjures up images of someone wearing a balaclava and using a laptop to steal bank accounts. To the uninitiated public, a hackerspace is distinct from a makerspace. In reality, they are remarkably similar: a hackerspace has a room filled with tools; a makerspace has a room filled with tools that allow people to control their language. Little difference, really, if you discount the [Frank Luntz]-level wordsmithing.

While this could go badly for any ~space in Germany with a ‘maker’ prefix, trademarking ‘makerspace’ isn’t really that much different from calling it a TechShop, and the trademark application is probably just a product of lawyers. In any event, it looks like  UnternehmerTUM MakerSpace GmbH has a pretty cool space; 1500m² (16000sq ft) of space, a water jet, and even some sewing equipment. We’d be happy to take a tour, so long as they don’t enforce the trademark.

Thanks [Moritz] for the tip.

Crazy Whirlwind Pre-Hackaday Prize Launch Tour

The Hackaday Prize was about to launch but the date wasn’t public yet. I decided to do a pre-launch tour to visit a few places and to drop in on some of the Hackaday Prize Judges. It started in Chicagoland, looped through San Francisco for a hardware meetup and Hardware Con, then finished with visits to [Ben Krasnow’s] workshop, [Elecia White’s] studio, and the Evil Mad Scientist Laboratories.

The Prize is now running and it’s time for you to enter. Look at some of the awesome hacking going on at the places I visited and then submit your own idea to get your entry started. Join me after the break for all the details of the adventure.
