Our friends at Freeside Atlanta have been keeping busy despite the city-stopping snowstorms they’ve been suffering recently. This time it’s a 3D printer with dual extrusion: the LATHON printer. [Nohtal] bought his first 3D printer only two years ago, but his experiences led him to build his own to overcome some of the issues he encountered with standard printers.
The LATHON keeps the bed stable and instead moves only the nozzles, using Bowden extrusion to reduce the weight on the moving parts. A key feature is the addition of a second nozzle, which usually limits the print area. The LATHON, however, maintains a 12″x9″x8″ build volume thanks to the Bowden extruders. [Nohtal] documents the majority of his build process on Freeside’s blog, including using a plastic from GE called Ultem 2300 for the print bed, and running the printer through its paces with a slew of materials: ABS, PLA, HIPS, Nylon, TPE, Wood, and Carbon Fiber. You can find more information on the Kickstarter page or at lathon.net

Cruising around town, not sure what to do — oh hey look, someone is at the hackerspace! Introducing the Mobile Spacestate Indicator!
During our Hackerspacing in Europe tour, we had the pleasure of visiting ACKspace in Heerlen, the Netherlands. And like many hackerspaces, they have an online status indicator letting members and non-members alike know if the space is open. [Vicarious], the gentleman who kindly picked us up from the train station, has just finished off an awesome modification to his car. Using an Arduino Uno and a Raspberry Pi, he has created a mobile indicator of his hackerspace’s status.
The Raspberry Pi automatically tethers to his phone and checks the status of the hackerspace online. It then sends the data to the Arduino Uno which controls a small strip of RGB LEDs. He’s cleverly hidden all of this inside his center console, and it looks awesome!

Last super bowl Sunday, instead of checking the game, [Mattw] decided to extend a design and make a PCB of a trinket clone. [Mattw] altered a trinket clone design by [Morgan
Penfield Redfield] to shrink it down, perforated the USB connector to allow for easy removal and put most of the parts on a single layer.
After finalizing the design, [Mattw] put it into the LPKF Protolaser S that Seattle’s Metrix Create Space has. For those of you who don’t know, the LPKF protolaser uses a laser to directly ablate off the copper from the boards. This makes prototyping much faster without the need for a lot of nasty chemicals.
About six minutes in the Protolaser, some component placement by hand followed by a run through their reflow oven and [Mattw] had three boards ready to be tested. All told, about 4 hours from start to finish.
The end circuit looks great and the LPKF protolaser gives us a case of serious tool envy. If you’re like us and don’t have access to the fancy laser you might try our hand at this high-resolutino photo-etch process.
If you’re a seasoned hacker, you might find you need a portable workshop, because every moment away from home you feel a bit naked without access to all your tools and machines. It’s a bit of an older project that we’re quite surprised we never covered, but without further ado let us introduce you to [Steven Roberts’] Polaris Project trailer!
[Steven] is quite the seasoned hacker. In 1983, he took a 17,000 mile journey across America on a technology equipped bicycle — a very impressive feat at the time — seriously you won’t regret watching his video about it.
Anyway, fast forward to 2010, and [Steven] was invited to explain his new project on Make — with detailed build instructions! The 24′ mobile workshop utility trailer features thousands of electronic parts, cabinets filled with both hand and power tools, welders, a CNC router, a 2kW generator, a solar array, AGM battery backups, a ham radio, dedicated computer, soldering equipment, microscopes and more. It is quite literally packed to the gills with an amazing variety of tools.
The picture here doesn’t do it justice, so we recommend you check it out for yourself!
Is anyone planning on making their own mobile workshop? We don’t know about you, but we are now!
Ithaca Generator, a hackerspace in upstate New York, is running an indiegogo campaign for a laser cutter. With the recent stories of fires, and landlord problems hitting hackerspaces lately, we thought it would be good be to mention a space that is doing well and working to expand their tools. The Generator is looking to purchase a 60 Watt laser cutter. The flexible funding campaign is set for $3000 US, and they
are within striking distance of just passed their goal! As any laser veteran will tell you, $3000 isn’t nearly enough for a 60 Watt model from a reputable company. The group already has a donor who will match the campaign final funding amount up to $4000. If the campaign exceeds Now that the campaign has exceeded their goal, the extra funds will go toward a fume extraction systems for the new laser, as well as spare lenses and parts. The group has also added stretch goals for an extended warranty and an upgrade to 90 Watts of laser power.
Many of the donation perks include free membership to the hackerspace. [Vic Aprea], a member of The Generator board told us that out-of-town donors can gift these memberships to anyone local to the hackerspace. A membership would be a great gift for a Cornell or Ithaca college student. For more information on the generator and the campaign check out their website and the video after the break.

A few days ago, the folks at Nullspace Labs in downtown LA got a surprising memo: their building is going to be gutted in a month. With thirty days left, they need money to cover first and last months rent, and help with moving. We can imagine that moving a Hackerspace is no small feat, since they tend to accumulate tons of awesome stuff.
The Hackerspace has started a crowd funding campaign, and has posted a call for help. They are looking for money, new members, or help with moving. If you’ve never been, you can check out our tour of Nullspace Labs.
It’s tough deciding what Hackerspace news to cover. We can’t run individual features on every tip we get promoting Hackerspace events, developments, crowd funding campaigns, and calls for help. We’re featuring this one because we just visited them, they’re awesome, and they’ve also been the source for many great stories over the years, like craning in a laser cutter or developing a modular LED orb. So here’s a question for you: Should we be presenting more Hackerspace news that is perhaps only relevant at the local level? If you think we should, how would we present it? There’s the option of doing occasional links-post-like roundups. But if you have a better idea we’re all ears.
The HackPhx Winter 2014 hackathon was held at Heatsync Labs hackerspace in Mesa, Arizona, USA. The advertised theme was “Arduino Wearables”. Participating attendees were randomly placed on teams evenly distributed by their disclosed skills across all teams. There were 10 teams with 4 to 5 members per team competing for two winning spots.
Each team had to build an amazing wearable project utilizing the secret ingredient which was Seedstudio’s Arduino-compatible Xadow wearable platform and add-ons. The Xadow is similar to the Arduino Leonardo and participants used an Arduino cross compatibility and pin mapping chart to assist in development.
Top prize was the Judges’ prizes for the best completed and documented Xadow wearable team project. The second prize was the Jury’s prize given to the team project that the other teams liked the most regardless of event criteria.
Read more about the winning teams and watch their presentations after the break.
