Want To Create A FabLab In Your Garage? Start By Joining Your Hackerspace

August 31, 2015 by 58 Comments

For many hardware enthusiasts, it’s hard to stop imagining the possibilities of an almighty fablab in our garage — a glorious suite of machines that can make the widgets of our dreams. Over the years, many of us start to build just that, assembling marvelous workbenches for the rest of us to drool over. The question is: “how do we get there?”

Ok, let’s say we’ve got a blank garage. We might be able to pick up a couple of tools and just “roll with it,” teaching ourselves the basics as we go and learning from our mistakes. With enough endurance, we’ll wake up ten years later and realize that, among the CNC mill, lathe, o-scope, logic analyzer, and the graveyard of projects on the shelves–we’ve made it!

“Just rolling with it,” though, can squeeze the last bits of change out of our wallets–not to mention ten years being a long journey while flying solo the whole time.  Hardware costs money. Aimless experimentation, without understanding the space of “what expectations are realistic,” can cost lots of money when things break.

These days, the internet might do a great job of bringing people together with the same interest. But how does it fare in exchanging the technical know-how that’s tied directly to tools of the trade? Can we get the same experience from a chatroom as we might from a few minutes with the local ‘CNC Whisperer’ who can tell us the ins-and-outs about tuning the machine’s PID controllers?

I’d say that we just can’t. “Getting started” in any subject often seems daunting, but we’re at a compounded disadvantage in that the gurus on the forum have some shared implicit knowledge and jargon on the subject that we wont have if we truly are taking our first steps. (Not to fear, though; none of us were born with this stuff!)

Ruling out forums for taking our first baby steps, where can we find the “seasoned gurus” to give us that founding knowledge? It’s unlikely that any coffee shop would house the local hardware guru sippin’ a joe and taking questions. Fear not, though; there are places for hackers to get their sustenance.

A month ago, we ran a post about [Jim]’s rare and strange transparent microchips. He’s back at it again, this time taking a look at the inner workings of MOSFETs

The Unallocated Space hackerspace is moving, and they’re looking for a few donations to get the ball rolling.

Yes, it’s a Kickstarter for a 3D printer, but the LumiPocket is interesting, even if only on the basis of the engineering choices. It’s a UV laser resin printer, and they’re using a SCARA arm to move the laser around. They’re also doing a top-down resin tank; it requires more resin, but it seems to work well enough.

Around DC or northern Virginia? We’re going to be there on September 11th through the 13th. We’re holding a Hackaday Prize Worldwide meetup at Nova Labs in Reston, Virgina. Sign up now! Learn KiCAD with [Anool]! Meet [Sudo Bob]! It’ll be a blast.

Not around DC or NOVA? This Wednesday we’ll be hosting another chat on .io.

The GEnx is one of the most beautiful and advanced engines in the world, and that means [Harcoreta] oven on the RC groups forums has made one of the most beautiful electric ducted fans in the world. On the outside, it looks like a GEnx, including reverse thrust capabilities, but inside it’s pure electronics: a brushless motor rotates a 100mm, 18-blade fan. He’s hoping to mount it on a Bixler (!). We can’t wait for the video of the maiden.

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

June 11, 2015 by 5 Comments

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

June 4, 2015 by 2 Comments

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 inventory, layout, and guidelines at the CBA website.
