Adventures In Hackerspacing: GA Tech’s Invention Studio

GaTech's Invention Studio

We feature hacker/makerspaces of all kinds here at Hackaday, and these days, encountering a hackerspace at a college or university isn’t uncommon. School-backed spaces are often mildly impressive, too, with plenty of room and better-than-most equipment.

Georgia Tech’s Invention Studio, however, is different. This space is nothing short of staggering.

Once you’ve walked past the wall of commercial-grade 3D printers lining the entryway, you’ll find yourself in the Electro-lounge, a general meeting and hangout room with some basic tools. Each room beyond has a specific purpose, and is packed full of equipment. We aren’t just going on a tour, though, because this is Adventures in Hackerspacing. Click through the break for a behind-the-scenes look at how this hackerspace provides a top-rate experience for its makers and how Invention Studio thrives with an entirely student-run leadership.

This wasn’t my first trip to Invention Studio, but it was the first where I had time to sit and chat at length with some of the students and with my friend [Chad Ramey]: Computer Science major, fusion reactor operator, Invention Studio president, and all-around nice guy.

On the table in the Electro-lounge is a 3D printer model that I don’t recognize. [Chad] explains that manufacturers will sometimes send Invention Studio their prototypes because the students at Tech will drive them until the steppers fall off. There are few places that can provide that kind of continuous use and supply meaningful, technical feedback: the space accommodates hundreds of students during the school year and 3D printers are perhaps the most popular piece of equipment.

I follow [Chad] further into the depths of Invention Studio and into a room dedicated to consumer 3D printers, where printing ABS or PLA is free of cost to the student. [Chad] affectionately refers to this room as the Wild West of the Invention Studio, where students with good intentions but a lack of experience often break things. That’s okay, though. Tech has enough printers that anything short of a natural disaster wouldn’t inhibit their production capabilities, and allowing the students to fail helps foster a community of hackers who work to resurrect the devices together, leaving everyone with a better understanding of the printers.

Invention Studio Armband
The Invention Studio ULI’s armband.

Although Invention Studio has some faculty oversight (grant writing and fundraising, ensuring safety standards) the space is otherwise entirely student-run. The system centers around ULI’s, University Lab Instructors, who volunteer their time to supervise the various sections of the space. Anyone associated with the university has access to Invention Studio during regular hours, and at least 3 ULI’s are on duty during this time. Each wears an identifying armband.

Prospective ULI’s must first attend an introductory meeting to learn basic procedures and rules. after which they complete a competency check via an online document. ULI’s must volunteer a minimum of 3 hours per week. In return, however, they receive the keys to the kingdom and can use the facilities any time. Not literal keys, though; this is Georgia Tech. Access control is through NFC used by the Student IDs, but it’s a proprietary NFC standard rather than the typical RFID, which limits how the students can use the devices. For now, access to any given room happens through faculty request.

Some ULI’s naturally gravitate toward a particular interest and become “masters” of those areas—or, in the case of 3D printing, “masochists.” For these students, making is a consuming part of their lives, and they spend a lot of time around the shop, helping maintain their given area and provide some more advanced guidance.

Each tool has an acrylic silhouette for easy replacing.

[Chad] leads me out of the 3D printer room and through the rest of the Studio. We pass through the wood shop, which has a large CNC router and a slew of tools carefully organized along the wall—very cleverly, I should say. Each tool has its own piece of acrylic cut into the form of the tool’s silhouette and mounted on the wall behind it, to simplify the re-shelving process. Back near the entrance we encounter rows of sticker-laden lockers: personal storage is yet another ULI perk.

Inv Studio Waterjet
Who doesn’t want a waterjet?

A massive waterjet shares a room with a couple of laser cutters and a small kiln. Students don’t enjoy the same Wild-West-Freedom to tinker with these larger, more expensive devices as they would the consumer-grade 3D printers, and any malfunctions—although industrial equipment is less likely to break down than the RepRaps—are handled through the manufacturer. That doesn’t mean students are discouraged from using the equipment. Countless components are carved out of all types of material for everything from business cards to electric vehicles.

More equipment...
CNC lathes and more.

[Chad] has to turn the lights on in the last room he shows me. Inside is a fabricator’s dream space, packed wall-to-wall with CNC mills and CNC lathes. The room is unoccupied, however, and although Invention Studio isn’t busy at the moment, these machines don’t see as much use as I expected. 3D printing, as [Chad] explains, has stolen much of the attention away from other manufacturing techniques, but the occasional ambitious student will resist the urge to melt plastic and fire up one of these impressive machines instead.

Makers of all kinds.

If you’re looking for a hacker/maker-friendly college, Georgia Tech is hard to beat. Even during the slower hours of my visit I encountered at least five students actively tinkering away at a variety of projects. As a space, Invention Studio is one of the best I’ve seen: self-sustaining, student-run, welcoming and bustling with people who just love to make.

    1. You can start one! I started a MakerSpace at my school 4 years ago as a freshman and it’s still going strong. Just find a professor, find some dedicated students, and off you go. The space is much more about the people then the tools.

  1. whatever happens, NEVER make it hard to use the machines for students~! My uni has just about all the same stuff, but after many little incidents over the years, it’s near impossible to get to use any of it now! One instance, I had them machine peices of MDF for me, as they wouldn’t let me do it. Now they have a new rule “NO WOOD” because they had a huge saw dust issue! It’s not my fault that they don’t know what the heck a $200 dust collection system is. Also now I can’t use the equipment without a teacher approving the work I want, this rule immediately destroyed any chances of most students’ personal projects – which are where I learned most of my skills!

    Be nice, be forgiving, share, and you guys will have awesome students graduating, reinforcing the engineering departments’ epic viewpoint.

        1. To be fair, wood dust mitigation is rarely solved with a $200 solution. You need actual filters, cyclones, blowers, fire prevention considerations, grounding. It’s not as simple as one might think at first glance.

    1. We have very strict rules at the invention studio, and we enforce them. That’s the only reason we’ve been able to keep it this open and running so well.
      We’ve had to bann users permanently before for things as simple as not cleaning up after themselves, or working alone in the machining room. The ULIs are very vigilant against ignorance and any lack of common sense as well. We know that if anyone were to be seriously injured by any of the machines, the Invention Studio would be shut down completely. Luckily, though, the worst injuries we’ve had so far are cuts and scrapes.
      We definitely try to let student’s experiment and learn as much as possible, but at the same time we can’t be cavalier about letting just anyone hop on (the water jet, for example). We’ve had people break the nozzle tip because they didn’t know how to adjust the height properly. I probably don’t need to say how expensive those parts are. I tell people that if they’re not sure about how to do something, ask one of the ULIs, and we can almost always find a safe way (even if it is a bit unorthodox).

        1. I don’t know why the previous poster is being super secretive. Mixing tubes are about $100 if you buy them from resellers and about $135ish each if you buy them from the manufacturer (in this case, OMAX). They are functionally the exact same part, you just get to pay more. So each one you break costs about that, assuming nothing else broke. It happens. They are wear items so they wear out in addition to breaking. They are broken by an operator that directs the machine to slam into something, usually by accident or because the machine has no impact detection equipment (more likely). Such upgrades to exist, they don’t prevent every possible problem but they mitigate it quite a bit. Unless you simply intentionally or unintentionally lower the mixing tube into the part, in which case it probably isn’t going to help you prevent a broken mixing tube.

          Oh and waterjets normally bill out at about $150 per hour to run. Maybe less, depending on the machine and how often you have to rebuild them (direct drive vs intensifier). That assumes you are not breaking mixing tubes but instead using them until they wear out.

      1. Sounds fair to me.

        In chemistry labs, if you didn’t follow proper acid handling procedures, you were instantly kicked out of the class and likely faced further discipline from the department.

        HF and tert-Butyllithium are not compounds to play around with.

          1. even 400 level undergraduate classes for EEs have HF all over the place for silicon wafer manufacturing. I was scared every time I handled it.
