Fighting robots are even more awesome than regular robots. But it’s hard for us to imagine tossing all that money (not to mention blood, sweat and tears) into a bot and then watching it get shredded. The folks at Columbia Gadget Works, a Columbia, MO hackerspace had the solution: make the robots out of cardboard.
The coolest thing about building your robots out of cardboard and hot glue is that it’s cheap, but if they’re going to be a modest scale, they can still be fairly strong, quick to repair, and you’re probably going to be able to scrounge all the parts out after a brutal defeat. In short, it’s a great idea for a hackerspace event.
If you’re going to pass the hat for donations to your hackerspace, you might as well add to the value proposition and give potential donors a little something for their generosity. And what better way to cash in than to channel the inner Brony in your donors with a My Little Pony themed dollar-bill vortex box?
Sick of the boring cheezy-poof jug her hackerspace was using as a donation jar, not-a-Brony [Michelle] was inspired by the CRASH Space mascot Sparkles, pictured left, to build a new box that will maximize donations by providing donors with a multimedia extravaganza. The Plexiglas box, resplendent with laser-cut acrylic hearts and spangled with My Little Pony stickers, is fitted with a sensor so that donations trigger an MP3 of the MLP theme song. A scrolling LED marquee flashes a gracious message of thanks, and to complete the experience, a pair of fans creates a tornado of the fat stacks of cash in the bin.
Putting a little [Twilight Sparkle] into your donation box makes good financial sense, as does providing incentive to deposit bills rather than coins. This project reminds us of our recent post about a custom claw machine which could be leveraged as a value-added donation box – just add a coin slot. And rainbows.
If you’re in the DC area, clear your schedule this Saturday night. Hackaday is hosting a Meetup at Nova Labs starting at 6pm. All you need to do is let us know you’re planning to attend.
The Reston, Virginia hackerspace is minutes away from Dulles airport. If you haven’t stopped by the hackerspace since they moved this is a great chance to see the new location. Bring along any hardware you’re working on. You can give a lightning talk about it, or just show it off casually while enjoying some food and beverage. Several members of the Hackaday crew will be on hand: [Anool Mahidharia] will be in town presenting a weekend-long workshop on PCB design using KiCAD. [Mike], [Brian], and [Sophi] will join him for the meetup on Saturday evening. For more details on what is going down that weekend take a look at the original announcement post. See you soon!
Last week we got an invitation in the Hackaday tip line to attend the grand opening of a hackerspace in Troy, New York. Styling itself the Tech Valley Center of Gravity, the group seemed intriguing – a combination of makerspace and business incubator. But what was this about a grand opening? Hackerspaces don’t open – they just occupy a found space and grow by accretion until they reach a critical mass of equipment and awesomeness. I decided I needed to see this for myself, and being only a two-hour drive from my home, I headed off with my kids in tow and a small pile of Hackaday swag to see what a ribbon cutting for a hackerspace would be like. Plus I absolutely had to find out what in the world a “Quackenbush Building” was.
I was not disappointed. The Center of Gravity is a really special group of folks with an incredible vision of what it means to be hackers. Hackerspaces make a lot of things – great projects and gadgetry, plus sawdust, metal chips, and the occasional puff of Magic Blue Smoke. The Center of Gravity makes all of that, but it also makes entrepreneurs, businesses, and actual products. And it can reasonably claim to have a hand in community renewal.
I have to admit my first impression of the event was a little confused. There was a huge crowd stuffed into the high-ceilinged first floor of an old building taking up most of a city block. There were a few 3D printers set up on tables, and groups of people demonstrating cool stuff – my son was especially keen to try the Airsoft rifle interface to Counterstrike. But the whole thing had a decidedly science fair atmosphere to it, with obvious civilians mixing and mingling with the black t-shirted hackers. There were also quite a few folks in business attire, plus white-shirted wait staff circulating with appetizers and drinks. But where was the machine shop? The laser cutters? The electronics benches and oscilloscopes and function generators? Where were the projects in various states of assembly? Had I driven all this way just to see a community outreach event?
Disappointed, I headed down the stairs to the basement, which was mercifully cooler than the first floor. Ah, ha! Here were the shops – huge and brand new, with separate areas for woodwork and metalwork. And here I met [Bob Bownes], vice president of CoG, serial entrepreneur, and the fellow who invited me. And this is where I finally learned the full story of what was going on.
The ribbon cutting that was going on upstairs – the ribbon being a copper braid and the scissors being a MIG welder – was the official start of the CoG’s residency in its new space in the renovated Quackenbush Building. Built in the 1850s, it was home to the Quackenbush Department Store until the 1930s, when it switched hands to another chain. It finally became a Rite Aid pharmacy which, in a sign of the hard times Troy would fall upon, closed in the early 2000s. The beautiful old building was purchased by a local developer, renovated with the help of various state grants, and its 48,000 square feet were turned over to the CoG group, who could now move out of their cramped and confining home in the bottom of a parking garage that was once a McDonald’s and an off-track betting parlor.
It wasn’t just good fortune that lead to the CoG being able to expand so dramatically. As [Bob] explained, the CoG had been designed from the ground up to be a business incubator as well as a hackerspace. If you have an idea, you can turn it into a product in the CoG hackerspace, then turn the product into a business in the incubator. The upper two floors of the Quackenbush are devoted to the incubator, which provides fledgling companies with access to administrative functions, provides conference and office space, and helps get businesses off the ground.
One such business is Vital Vio, a maker of visible light disinfection fixtures. Vital Vio got its start in the aforementioned former McDonald’s, and will take advantage of the 3,000 square foot light manufacturing swing space in the basement of the Quackenbush to ramp up its production. The goal is to have Vital Vio and the companies that will no doubt follow it move on to space of their own, at which point the next company will take over the swing space for their first manufacturing operation – hack, rinse, repeat. With quite a few businesses already in the incubator stage, it should be exciting to watch what comes out of the CoG over the next few years.
I had been to Troy a few times back in the ’80s and ’90s, and I wasn’t impressed. It always seemed seedy and run down to me, like so many towns and cities in the northeast US that had their manufacturing hearts ripped out of them in the 1970s. But the Troy we saw on Wednesday was a totally different place – vital and happening, with bistros and bakeries and funky public spaces. [Bob] explained that CoG had plenty to do with that – at least six new companies had relocated to the area around the Quackenbush specifically because of CoG. And it’s hoped that the businesses that spin off the incubator will choose to stay close to the nest, which will attract more businesses and more people to the area. That’s quite a change from the point where even a McDonald’s and an off-track betting parlor are no longer viable.
My trip to the Tech Valley Center of Gravity was not your typical hackerspace tour, but the CoG is not your typical hackerspace. There’s a lot to be said for the vision that created this place, and the model they’ve adopted for churning out businesses really seems to be working. Almost the entire incubator space is spoken for already, so there are plenty of companies waiting to be born there. That’s not to say that the average hacker who just wants a place to play won’t feel at home in the CoG – there’s plenty of room for them too, and the CoG even welcomes families with special memberships and STEM outreach programs. But if you have the germ of an idea, it can go from product to business with the help of a place like this, and that’s a pretty cool idea.
My thanks to [Bob], [Matt] and [Tait] for taking so much time out of their celebration to show us around. I hope we can visit again once everything is moved and you’re settled into your awesome new home.
We were in Boston last week and Artistan’s Asylum welcomed us in to host a Hackaday Meetup. We usually pack the place when the Hackaday community turns out, but this was exceptional. This hackerspace has a sizeable open area that I’m told fits triple-digits and we were using all of it. In addition to food and beverage (courtesy of our parent company Supplyframe who also make trips like this one a possibility), we had lighting talks for people to show off their projects. One of the hits was a functional hoverboard shown above, but there were dozens of others.
Here is the quick gallery of images (from our Hackaday.io event page) to give you an overview. After the break you’ll find dozens more highlighting the builds which were being shown off.
We brought the Hackaday Omnibus with us

We’re in Boston this week and my first stop was at MITERS last night. This is the MIT Electronics Research Society, which started as a way to provide free access to computers for all students. Since those humble beginnings the organization has grown to include a slew of fabrication and test hardware, as well as a vibrant community that makes the group a great place to hang out.

Ah, the comfort of a hackerspace

Walking into the building you’re greeted with double doors strewn with interesting electronics and many examples of fabrication in the form of the word MITERS. The group, which is pushing 60-years of existence, feels immediately like a hackerspace where creativity and anarchy duke it out in a wild dance of experimentation. On this particular Wednesday evening we encountered a room of about 10 people working feverishly to fabricate electric racers for the PRS racing circuit in Detroit this Saturday.
Like a hackerspace, MITERS is completely member (read: student) run. There is a board that helps keep things on the rails. There is no membership fee; funding for the organization is sourced from Swapfest, a weekly flea market during the summer.
Machinist’s tool kit
CNC machine tools
There is a strong slant toward machine shop at this hackerspace. In addition to a respectable Bridgeport CNC Mill, the machine tools and hand tools provide for almost all your fabrication needs.
Uni-balancer and it’s creator
Black strip is the deadman switch
What can be built in this space? How about a unibalancer? This is a single-wheeled, human-ridable vehicle that has a 7-mile cruise radius between charges. For me the most interesting feature is the deadman’s switch. You know those black rubber strips on public buses that you press for the next stop? This unibalancer has one that you need to stand on to make it go.

Tiny electric racer
The hackers at MITERS excel when it comes to electric vehicles and this time of year that means the Power (Wheels) Racing Series. There are restrictions on size, and power output so the teams squeeze every bit that they can. For me, the most interesting build is based off of a pair of Ryobi electric chainsaws. The 40V batteries for these are themselves quite formidable but not used at all in the build. The team has reverse-engineered the driver circuits and written their own firmware for the STM8 microcontrollers on the boards. The chainsaws use chains to drive the two rear wheels. The entire system is monitored with XBEE-based wireless data which is displayed on a tablet.
This isn’t the only PRS build. The MITERS plan to take three different vehicles with them this weekend. The one they can’t bring is the huge electric shopping cart (with mandatory wheelie bar) which hangs from the ceiling of the space.
Best sounding musical Tesla I’ve seen
Top coil of massive tesla coil
In addition to the formidable fabrication projects, there are a multitude of electronic projects to be seen. There is a musical tesla coil which is the best I’ve ever heard. It could easily be mistaken as a proper speaker. If you need more bass there’s a massive ceiling-mounted sub-woofer for that. And if you want a more formidable tesla coil, the parts are there.
Look hard enough and you’ll even find battle robots. This one had diamond plate that spins with a variety of nasty accoutrements intended for maximum damage of its foe. On the underside you’ll see a brushless motor used the opposite of how you might think. The shaft is attached to the locomotion frame of the bot. The underside of the spinning diamond plate has a ring of antistatic mat against which this brushless motor body spins.
Thanks to the MITERS for welcoming us in. It was a blast seeing all of the projects they’re working on!
Meetup at Artisan’s Asylum Tonight
If you’re in the Boston area, head on over to Artisan’s Asylum tonight starting at 6. They were gracious enough to open their doors for a Hackaday Meetup. Bring some hardware to show off if you can, if you can’t that’s fine as well. We’ll have a few lightning talks, some social time, and maybe an afterbar!
To wrap things up, we have covered a few projects from MITERS already, like this Power Wheels Racing build, and an electric go kart done the right way. Now that we’ve met them in person we’ll be on the lookout for a lot more awesome hacks from them.
One practical use of large switches and indicator lamps is to make a power distribution panel which can be useful when you want to control and monitor the power consumption of numerous devices such as your electronics work bench or amateur radio station. Old-school in appearance and using military surplus electronics, this power distribution panel allows for control of outlet on back. Did I mention I built it when I was 16?
Building it was easy, 120 VAC line enters through a main breaker. It is fed through an AC amp meter (with built-in shunt) then to a line filter. From the line filter it goes to a line voltage meter and filament transformer to power the indicator lamps. This AC line is then bussed out to the circuit breakers. Each breaker controls one outlet on the rear panel. As devices are switched on or off the current draw can be measured. This is well demonstrated in the video overview found after the break.
Be creative. Use military surplus switches, indicators, and other unique looking hardware. Customize to give your preferred mad scientist look while also providing valuable functionality.
