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.

SXSW Create: ATX Hackerspace Area

We had a wonderful time over the weekend at the 2015 SXSW Create. I was really excited to see that there was a very large area set aside for the Hackerspaces of the Austin area and they took full advantage of that. Most notably, ATX Hackerspace who had multiple tables and was drawing a huge crowd.

sxsw-atx-thereminThis table is a good example of the demonstrations on hand. Primarily It’s a collection of ultrasonic theremin. The classic theremin uses oscillator-based sound production (we’ve been running a series on that concept) with a set of antennas that uses your body’s proximity to tweak that signal. This version mimics the user interface but greatly simplifies the skillset needed to produce the instrument by swapping the antenna for an ultrasonic rangefinder and generating the audio digitally. The more astute viewer will have noticed the instrument being held. I neglected to ask about this but it sure looks like a Holophonor which is another great seed idea for your next project. Update: it’s a Hulusi.

sxsw-atx-solderingI do think it’s worth noting that ATX also set aside a lot of table-space for their members to actually work on building projects at the event. We’re big advocates of this rather than simply exhibiting finished projects. It doesn’t really matter what you’re working on; seeing a table covered with interesting parts and tools, being worked on by fun people obviously enjoy each other’s company is the core message of a Hackerspace… right?

I talk with [Gardner] about ATX in the video after the break, and make a quick loop around the display tables.

Powered Double Pendulum is a Chaotic Display

If you’ve never seen a double pendulum before, it’s basically just a pendulum with another pendulum attached to the end. You might not think that’s anything special, but these devices can exhibit extremely chaotic behavior if enough energy is put into the system. The result is often a display that draws attention. [David] wanted to build his own double pendulum display, but he wanted to make it drive itself. The result is a powered double pendulum.

There aren’t many build details here, but the device is simple enough that we can deduce how it works from the demonstration video. It’s broken into two main pieces; the frame and the pendulum. The frame appears to be made mostly from wood. The front plate is made of three layers sandwiched together. A slot is cut out of the middle to allow a rail to slide up and down linearly. The rail is designed in such a way that it fits between the outer layers of the front plate like a track.

The pendulum is attached to the linear rail. The rail moves up and down and puts energy into the pendulum. This causes the pendulum to actually move and generate the chaotic behavior. The rail slides up and down thanks to an electric motor mounted to the base. The mechanics work similar to a piston on a crankshaft. The motor looks as though it is mounted to a wooden bracket that was cut with precision on a laser cutter. The final product works well, though it is a bit noisy. We also wonder if the system would be even more fun to watch if the rotation of the motor had an element of randomness added to it. Or he could always attach a paint sprayer to the end.

1.37″ CRT Restored by Hacklab for Miniature MAME Cabinet

For $5, [William] of Toronto’s Hacklab hackerspace got a hold of one of the smallest CRT screens ever made – about the size of a large coin. Over the course of a couple sessions – including a public hack boothside at their Mini Makerfaire – [William], [Igor], and several other members managed to connect it as a monitor directly off a Raspberry Pi. The end-goal is the world’s smallest MAME cabinet (smaller by almost half than this LCD one).

As Canada followed the US and stopped broadcasting analog back in 2011, it became quite a challenge to feed the screen a video source. They disclosed early that the easiest solution would just be an RF transmitter on the Pi and then tune the micro-set to that channel. Too easy. They wanted something elegant and challenging so they went digging into the circuitry to find a place to insert a composite video signal directly.

The real story here is their persistence at reverse engineering. The PCB was folded like a cardboard box to fit in the original case, making large portions of the circuitboard and wiring inaccessible. Even when they managed to trace the signal to what they thought was the appropriate chip (marked C80580), they could not find any information on the 30 year old chip. Noting that every other chip on the board was Panasonic and started with “AN5”, [Igor] suspected the mystery silicon was just renamed and went through every single datasheet he could find with that prefix. Combined with form factor, pin count and purpose, his sleuthing was rewarded with a guess for a match – the AN5715. His hunch was correct – using that datasheet led him to the answers they required.

Then they just had to figure out how get the composite signal the Pi outputted into something the chip would use to display the correct image. There were no shortage of challenges, failures and dead ends here either, but they had help from the rest of their membership.

Their project log is an interesting narrative through the process and in the end of course, it worked. It is displayed beautifully with a clear acrylic case and ready for a cabinet to be built.

Push Button, Receive Bacon.

Members of the Rabbit Hole hackerspace spent the last weekend competing in The Deconstruction, a 48 hour hackathon competition. The hackerspace’s theme was “Light it up!”, so members created some awesome projects involving light. The star of the show was their bacon cooking machine. The Rabbit hole made the “Push Button. Receive Bacon” meme real.

A broken laser printer was gutted for its drive train and fuser assembly. Laser printer fusers are essentially hot rollers. The rollers melt toner and fuse it with paper as it passes through the printer. The heat in this case comes from a lamp inside the roller. That lamp also puts out plenty of light, which fit perfectly with the team’s theme.

The Rabbit Hole members wasn’t done though, they also built a pocket-sized infinity mirror from an empty Altoids tin. The bottom of the tin was cut out, and a mirror glued in. A filter from a broken projector made a perfect half silver mirror, and some LEDs completed the project.

The members also built a fandom art piece, consisting of 25 fans connected together in a skull shape. The eye and nose fans were lighted. When the fans were plugged in, they kicked for a few seconds before spinning up. Once they did spin though – there was a mighty wind in the Rabbit Hole.

Click past the break for The Rabbit Hole’s Deconstruction video!

Because You can’t go to germany without seeing model trains

As with all our extracurricular adventures, we needed to visit a few hackerspaces while in Munich. The first one was MCSM/Make Things Munich, formerly the Siemens Club for model engines. We’ve been to a few hackerspaces and have the passport stamps to prove it, and we can say without a doubt this space is unique.

MCSM was a hackerspace before the concept of hackerspaces existed. Originally, this was the Siemens Club for Model Engines, filled with engineers from the Siemens plant tinkering with model trains, model boats, and models of anything that moves. One of the members that guided us through the space, [Carlos Morra] told us when he joined, he alone dropped the average age of the space’s membership by a decade.

Inside the space, you’ll find the usual tools and equipment – lathes, CNC mills, an electronics workbench, and a bunch of old but still valuable equipment. Most of this equipment was salvaged from the Siemens plant. The organization for this space, though, cannot be compared to anything I’ve ever seen. There are floor to ceiling cabinets filled with everything you can imagine, all carefully indexed and sorted.

Of course, being formerly called the Model Engine club, there will be an immense train layout. I counted at least five gauges of track in two sprawling layouts, one of which was easily 15 square meters. It’s a true hackerspace built from a model train club, how can it get better than that?

Pictures below.
