EMF Fire Pong

August 11, 2016 by Jenny List 8 Comments

One of the installations that consistently drew a large crowd after dark at EMF Camp 2016 was a game. This wasn’t a conventional computer game though, instead it was a line of gas jets along which a pair of players had to bat a jet of flame between them at ever-increasing speed until one player missed the return. This was the Fire Pong game created by members of Nottingham Hackspace, and though there seems to have been no online write-up of it as yet they have posted enough pictures of its build for us to deduce something of its construction.

A network of gas pipes and jets with all valves brought out to a clearly labeled control panel appears to control the gas flow through solenoid valves connected to a relay board driven by what appears to be an Arduino Pro Mini. The bats are huge for theatrical effect, but contain accelerometers to sense player swipes and send the information back to the gas control circuits. A pair of much larger flame generators indicate the end of a rally, and the score is displayed on a large LED scoreboard. There is very likely to be more to the system than we can glean from these pictures and a shot of the various components, but as yet we are so-to-speak in the dark on their details.

If you will excuse the quality constraints of a mobile phone camera in a darkened field, a video of the game in action is below the break. There was a significant queue for a turn at the bat, this was one of the event’s more popular night-time attractions.

EMF: You Shall Find Us At The Sign Of The Jolly Wrencher

August 4, 2016 by Jenny List 2 Comments

It’s frustrating, the reluctance of some of my fellow hackspace members to put the cordless drill battery back in the charger after use. As this is being written I’ve just coaxed enough energy from the drill to make a few holes in a piece of PVC pipe that will form part of an improvised flagpole, and upon that pole will hang Hackaday’s Jolly Wrencher flag at this weekend’s EMF Camp. We’re sharing a village with Oxford Hackspace, and as both your Hackaday scribe and an OxHack member the last week has been a little busy.

In theory it’s a simple enough process, getting a hackspace and all its assorted accoutrements down to Guildford. Three or four members’ cars will be loaded to the gunwales and will set off in good time to have everything under way without still desperately getting ready when the fun begins. In practice it’s been a procession of narrowly averted disasters, from the gazebo someone bought at auction turning out to have five walls and no roof, to the large ball that forms an essential part of one of the projects OxHack will be featuring being a buy-while-stocks-last remaindered product from last years Argos catalogue that only certain stores seem to still have.

We’ll be on the border between camping areas A and B, next to our friends from the Netherlands. I’m told that this location was requested due to likely proximity to a source of stroopwafels. If you come along on Friday between 6 and 8 PM we’re holding the Tindie bring-a-hack event, at which we’ll be inviting attendees to bring along their hacks to share with the masses. All projects are welcome, but if you have a Hackaday Prize entry, a Hackaday.io project or a Tindie item we’d especially love to see you. My colleague Jasmine assures me that there will be a limited amount of Hackaday and Tindie swag on offer.

If you’re going down to EMF Camp this weekend then please drop by and have a chat if you’re passing our village. Otherwise you’ll probably encounter us on our travels as we try to seek out the interesting projects and hacks to feature on these pages. We hope the British weather doesn’t deliver any unpleasant surprises, and may all your projects work when you demonstrate them in front of the masses!

Door Iris Porthole Is The Perfect Fix For Detroit Hackerspace

July 9, 2016 by James Hobson 31 Comments

In order to resolve the problem of congestion at the entrance to their hackerspace, the minds at i3Detroit installed a motion-activated mechanical iris in their door’s porthole.

Grabbing the design online (which they are now hosting on their site here), the parts were laser cut out of wood, gold leaf was added for effect, and it was relatively easy to assemble. PIR sensors detect movement on both sides of the door and an FET resistor connected to an orange LED add some old-school science fiction flair. The iris is actuated by a 12V car window motor — which works just fine on the 5V power that it’s supplied with — and an Arduino filling in as a controller. Start and stop positioning required some limit switches that seem to do the trick.

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.

Inside The Supplyframe Design Lab On Opening Night

June 28, 2016 by Mike Szczys 13 Comments

Last week the Supplyframe Design Lab in Pasadena opened it’s doors, welcoming in the community to explore the newly rebuilt interior which is now filled with high-end prototyping and fabrication tools and bristling with work areas to suit any need. I had a chance to pull a few people aside during the opening night party to talk about how the Design Lab came about and what we can expect coming out of the space in the near future.

Opening night was heavily attended. I recognized many faces, but the majority of those exploring the building were new acquaintances for me. This is likely due to a strong connection the Design Lab is building with the students, faculty, and graduates of the ArtCenter College of Design. Located just down the road, it is one of the top design schools in the world.

Supplyframe Design Lab Opens Its Doors

June 23, 2016 by Mike Szczys 22 Comments

Today marks the opening of the Supplyframe Design Lab in Pasadena, California. The Design Lab bills itself as the “leading edge creative center built to foster new ideas in technology and design”. Supplyframe had the vision to acquire Hackaday a few years ago, launched the Hackaday.io Community site which now has more than 150,000 members, and established The Hackaday Prize to spark engineering projects that benefit humanity. Pay attention to the Design Lab; looking back on this day you’re going to be able to say that you remember when it all started.

Othermills lined up and ready to go

SeeMeCNC Rostock Max V2 and Deezmaker Bukito 3D Printers

Shopbot, Tormach, and Woodworking Tools

The equipment enshrined in the new space is spectacular. Name your material, and there are tools to work with it. Working with electronics? Mill your prototypes on a number of OtherMills available. Custom enclosure? Take your pick of milling it on the Tormach, PolyJet printing it on the Statasys, or FDM printing with a number of different high-end 3D printers. Need design software and beefy boxes to run it on? They have that too. Working in wood? A shopbot awaits you, as do traditional tools like a tablesaw, routers, sanders, etc. It’s a wonderland for making the imaginable real. If there ever was a time to quit your job and spend three months launching that dream product, this is it. The Design Lab has a residency program.

Supplyframe is all about enabling hardware creation. This is what sites like Parts.io and Findchips.com do: provide powerful tools for hardware engineers to better use their design skills. Founding a space like the Design Lab is a natural extension of this. Providing a work area, mentorships, and funding residencies breaks down the barriers that can prevent new hardware seeing the light of day. The Design Lab solves the issues of tools, materials, and hands-on experience that plague many a new hardware company.

Residencies will start on July 1st. Each runs for three months in which residents have unfettered access to the space and its tools, as well as financial support of $2000 per month. Each resident will self-identify into the product-track (you’re on your way to market with new hardware) or the art-track (you have a calling for an ambitious project and need to make it a reality). So far the Design Lab page lists three residents; a network of low-cost air quality sensors called Scintilla, a music synthesizer based around Teensy 3 called NanoEgg, and a mixed-reality public arts initiative called Perceptoscope. The Design Lab is still accepting applications for new residencies this summer and beyond — one of these residencies will also be offered to the Grand Prize winner of the 2016 Hackaday Prize.

New CNC Machine? DIY Machinable Wax!

June 11, 2016 by Jenny List 25 Comments

The folks at Leeds Hackspace have built themselves a shiny new C-beam based CNC mill. As you might expect everyone wants to try the machine out, but there’s a problem. A CNC machine presents a steep learning curve, and a lot of raw materials (not to mention cutting bits) can be used in a very short time. Their solution is simple: mix themselves some machinable wax from LDPE pellets and paraffin wax, then easily recycle their swarf and failed objects back into fresh machinable wax stock.

Making the wax recipe is not for the faint-hearted, and involves melting the LDPE pellets and wax to 130 degrees Celcius in a cheap deep-fat fryer. They bought the cheapest fryer they could find at the British catalogue retailer Argos, you really wouldn’t want to risk an appliance you cared about in this exercise.

Colouring came from an orange wax crayon, though they note recycling of mixed colours will inevitably result in a muddy brown. The finished mixture was poured into Tupperware lunchboxes to set, and the resulting blocks were trimmed to square on a bandsaw. The Tupperware proved not to have a flat bottom, so later batches were cast in a loaf tin which proved much more suitable.

We’ve mentioned the machinable wax recipe before here at Hackaday, but it’s worth returning to the topic here with a description of it being used in the wild. Having watched other environments get through learning materials at an alarming rate with very little to show for their effort, we can see it makes a lot of sense as a training material.
