Giant D20 Is A Critical Hit In More Ways Than One

September 24, 2017 by James Hobson 18 Comments

[Mikael Vejdemo-Johansson] is a member of the NYC Resistor hackerspace and an avid fan of a D&D themed improv theatre called The Campaign. To show his appreciation, he decided to gift them a Christmas present: a giant D20. The original plan called for integrated LEDs to burst alight on a critical hit or miss, or let out pulses if it landed on another face. Cool, right? Well, easier said than done.

[Vejdemo-Johansson] figured a circle of 4 tilt sensors mounted on the one and twenty face would be enough to detect critical rolls. If any of the switches were tilted beyond 30 degrees, the switch would close. He mounted eight ball-tilt switches and glued in the LEDs. A hackerspace friend also helped him put together an astable multivibrator to generate the pulses for non-critical rolls.

This… did not work out so well. His tilt sensor array proved to be a veritable electronic cacophony and terribly sensitive to any movement. That and some other electronic troubles forced a shelving of any light shows on a critical hit or miss. [Vejdemo-Johansson] kept the pulsing LEDs which made for a cool effect when shining through the mirrored, red acrylic panes he used for the die faces. Foam caulk backer rods protect as the die’s structure to stop it from being shattered on its first use.

Before The Campaign’s next show, [Vejdemo-Johansson] managed to stealthily swap-out of the troupe’s original die with his gift, only for it to be immediately thrown in a way that would definitely void any electronic warranty. Check out the reveal after the break (warning, some NSFW language)!

Hackerspace Jukebox!

June 2, 2017 by James Hobson 11 Comments

Depending on whom you talk to, music can be an integral part of getting work done. At the Hackheim hackerspace in Trondheim, Norway, [Nikolai Ovesen] thought that the previous system of playing music over Bluetooth took away from the collaborative, interactive spirit of the space. Solution: a weekend build of a Raspberry Pi-powered jukebox.

The jukebox is simply laser-cut from plywood and bolted together. Inside, the touchscreen is mounted using double-sided tape, with the Raspberry Pi 3 and buck converter mounted on its rear with motherboard spacers. An IBM ThinkPad power cable was re-purposed and modified so it supplies the amp, as well as the Pi and touchscreen through the buck converter.

Once everything was connected, tested, and fired up, a bit of clever software working around had to be done in order to get Golang working, along with setting up the touchscreen and amp. Hackers interact with the jukebox using the Mopidy music server and its Mopify(Spotify) plugin — but they can also request songs through a bot in the Hackheim Slack channel.

Trademarking Makerspace (Again)

April 11, 2017 by Brian Benchoff 31 Comments

A British company has filed a trademark application for the word ‘MakerSpace’. While we’ve seen companies attempt to latch on to popular Maker phrases before, Gratnells Limited, the company in question, is a manufacturer of plastic containers, carts, and other various storage solutions. These products apparently provide a space to store all the stuff you make. Something along those lines.

This isn’t the first time we’ve seen someone try to glom onto the immense amount of marketing Make: has put into the term ‘makerspace’. In 2015, UnternehmerTUM MakerSpaceGmbH, an obviously German tech accelerator based in Munich, filed an application to trademark the word ‘Makerspace’. A few days later, we got word this makerspace wasn’t trying to enforce anything, they were just trying to keep the rug from being pulled out from under them. It was a defensive trademark, if something like that could ever exist (and it can’t under US trademark law). Swift and efficient German bureaucracy prevailed, and the trademark was rejected.

The trademark in question here covers goods including, ‘metal hardware and building materials’, ‘trolleys, trolleys with trays’, ‘guide rails of non-metallic materials’, and ‘lids for containers’, among other storage-related items. While this is far outside the usual meaning for a ‘makerspace’ – a building or club with a whole bunch of tools – if this trademark is approved, there is always the possibility of overzealous solicitors.

Fortunately, Gratnells released a statement today saying they would not defend or continue this trademark. This is in light of the recent, limited reaction to the trademark application. The word Makerspace is safe again another day.

Thanks [Tom] for the tip.

Hackerspaces Are Hard: Insurance

July 19, 2016 by Kristina Panos 48 Comments

Do you dream of opening a hackerspace, makerspace, or co-working space? Maybe it’s in the works and you’re already scoping out locations, intoxicated by visions of all the projects that will emerge from it. Here’s a sobering thought: makerspaces are a great big pile of risk. If the doors of your ‘space are already open, perhaps you’ve come to realize that the initial insurance policy you signed doesn’t really fit the needs of your particular creative paradise. Even if it does, the protection you need will change as you acquire new toys.

So why should you even get insurance? For one thing, your landlord will probably require it. If you own the building, you should insure it to protect yourself and anyone who uses the space. Do it for the same reason you’d insure a car, your house, or your collection of vintage pinball machines: to mitigate risk. It takes a lot of hard work to open a makerspace, perform the day-to-day operations, and keep it growing and getting better. Whenever the unthinkable happens, insurance will protect your investment as well as the people who make it a great place to be.

In researching this article, I contacted several well-established makerspaces in the United States as well as most of the major insurance providers to get both sides of the story. My intent was not to make a how-to guide, but to simply explore the topic and provide a view of the process and the struggle.

Makerspace North, From Empty Warehouse To Maker Magnet

June 30, 2016 by Steven Dufresne 5 Comments

Makerspace North is unique out of the 5 makerspaces in the Ottawa, Canada area in that it started life as an empty 10,000 square foot warehouse with adjoining office spaces and large open rooms, and has let the community fill it, resulting in it having become a major hub for makers to mix in all sorts of ways, some unexpected.

Many makerspaces are run by an organization that provides tools that groups or individuals use, along with qualification courses for select tools. Makerspace North, on the other hand, provides the space and lets the community provide the maker component. The result is a variety of large scale events from indoor drone flying and various types of maker faire style days, to craft shows, garage sales, and even concerts. Smaller meet-ups, most often open to anyone, are held by such groups as the Ottawa Robotics Club and the Ottawa Electronics Club as well as some more general ones. Courses offered by the community are also as varied.

This also means that the owners of Makerspace North don’t provide tools for people to use, but instead provide dedicated rental space. That doesn’t mean there aren’t tools — it means that Makerspace North encompasses a microcosm of various renters who fill out the task of things like tool rental. This is just one example of how the community has embraced the unique approach. Let’s take a closer look at that and a few other novelties of this system.

How To Set Up And Run A Makerspace

June 16, 2016 by Moritz Walter 34 Comments

A bunch of people who share a large workshop and meet on a regular basis to do projects and get some input. A place where kids can learn to build robots instead of becoming robots. A little community-driven factory, or just a lair for hackers. The world needs more of these spaces, and every hackerspace, makerspace or fab lab has its very own way of making it work. Nevertheless, when and if problems and challenges show up – they are always the same – almost stereotypically, so avoid some of the pitfalls and make use of the learnings from almost a decade of makerspacing to get it just right. Let’s take a look at just what it takes to get one of these spaces up and running well.

Hacking Education – A Makerspace Experiment

January 19, 2016 by Anool Mahidharia 18 Comments

This is an Education hack, and it’s pretty awesome. [Abhijit Sinha] received an Engineering degree and took up a run-of-the mill IT job in Bangalore, considered India’s IT hub. 7 months down the line on Dec 31st, he gave notice to the company and quit his “boring” job. He ended up in Banjarpalya, a village just 30 kms out of Bangalore. But it could well have been 30 years back in time. The people there had never come across computers, and there wasn’t much sign of other modern technology. So he set up Project DEFY – Design Education for You.

He bought a few refurbished laptops, took a room, and put kids and computers together. Except, these kids just knew a smattering of English. They went to the village school, run by the government and staffed by teachers whose training was basic, at best. He told the kids there are games in those boxes for them to play, but they’d have to figure it out on their own, without help from him. Pretty soon, all of them were playing games like they were pros. That’s when [Abhijit] stepped in and told them that they’d created a base line for having fun. Everything else they did from now on had to be more fun than what they had just done. If they were interested, he would show them how.

He had a gaggle of kids waiting to hear him with rapt attention. He showed them how to look online for information. He showed them how they could learn how to build fun projects by looking up websites like Instructables, and then use locally available materials and their own ingenuity to build and modify. Once a project was done, he showed them how to post details about what they had done and learnt so others around the world could learn from them. The kids took to all this like fish to water. They couldn’t wait to get through 5 hours of school each day, and then head over to their makerspace to spend hours tinkering. Check out their Instructable channel – and see if you can give them some guidance and advice.

A year onwards, on Dec 31st again, [Abhijit] gathered the kids, and several adults who had joined in during the year, telling them he had news. He had figured they were independent enough to run the space on their own now, without any help from him. He would still get them the 500 odd Dollars they needed each month to keep it operational. Other than that, they were on their own. He’s been monitoring their progress, and from the looks of it, the hack seems to have worked. More power to [Abhijit] and others like him around the world who are trying to bring the spirit of making to those who probably stand to benefit from it the most. Check out the videos below where they show off their work.

PS : Here’s the latest update from [Abhijit] : “Got back to the Banjarapalya Makerspace after quite a while, and this is what they show me – they built a little plane. Of course it crash lands, and needs a better programming, but I am super impressed that they are ready to fly.
Anyone who wants to help them technically? Financially? With parts and components ?”
