RBCreation: Down to the wire–30 minutes remain

 

 

 

We are down to the last 1/2 hour of the competition, an dour team is working so hard!

our team is exhausted — but they are finishing right down to the last second

The “WhirlyTubulator” will go live for demonstration at 6:30pm.

We know our team is really focused on getting their creation finished because we have not received an updated photo of Matt’s hair…

but here’s a snap of it on the live-feed; along with Eric and Sean!

We’re confident that our team will get rave reviews!

 

Recap: DIY Dentistry Class

Extract the fun!The i3detroit DIY Dentistry event was a big hit, and everyone had a fantastic time- at least until the anesthesia wore off! i3 member Dustin returned from a recent trip to Latvia armed with the knowledge and tools to make this class a jaw-crackin’ success.

Interest in self-dentistry is higher than ever. Thanks Obama!

A group of eager new mouth-hackers.

Dustin began the day with a brief history of DIY dentistry, and provided many DIY DOs and DON’Ts (for example, DON’T use bondo for fillings; DO visit Thingiverse for fillings and crowns you can 3-D print with ease.)

The hammerdrill setting is only for the most stubborn cavities.

Bob Ross: Happy Little Painters

We just had an awesome time running a paint-along class with everyone’s favorite late 80′s-early 90′s eccentric oil painter, Bob Ross.  Yelp was kind enough to sponsor us with free snacks and drinks for this event! i3 member, Kevin, (while donning a bob ross wig) guided the students through the intricacies of wet-on-wet oil painting.

The students spent two and a half hours following along creating a majestic mountain landscape while learning innovative ways of working with oil on canvas. While the paint will take about two weeks to dry, the painters were able to take their paintings home that day carefully transported with plastic wrap. The painters can now demonstrate their newly-learned skills in wielding a fan brush, and palette knife.

There was a huge demand for the event, so we will definitely be running more of these in the coming weeks. Stay tuned, and like us on facebook for future updates!

Member field trip: Quadrotors and datacenters

IMG_0062When first stepping through the door, the University of Michigan’s Walter E. Wilson Student Team Project Center feels familiar, like a well-equipped hackerspace/makerspace. A Haas vertical mill dominates the main floor, more modern than i3′s but otherwise similar. In the back are manual mills and lathes, and a nontraditional vehicle (in this case, a solar car) hangs from the ceiling. Upstairs, an electronics lab is giving rise to the next generation of self-contained autonomous quadrotor helicopters. There’s a feeling of easy camaraderie and a subtle sense that the future is taking shape within these walls.

What’s different about the Wilson STPC is that there’s no hobby activity here — no couch, no gaming, no rogue bumper stickers, no tinkering for the sake of tinkering. Use of the Center is for students only, of course, but beyond that, it’s restricted to official student teams competing in various events. Among them is the Michigan Autonomous Aerial Vehicles team, competing in the International Aerial Robotics Competition. Dissatisfied with the suitability of commercially available UAV platforms, MAAV is building their own, and they were kind enough to give i3 Detroit a behind-the-scenes tour on Sunday.

IMG_0085Unlike the internet-darling quadrotors performing aerobatics in a sensor-studded room, MAAV’s machines are almost entirely self-contained, designed to operate in an uncontrolled environment. So in addition to the obvious motors and rotors and batteries, they’re flying sensor platforms, with two onboard LIDAR units, accelerometers, gyroscopes, cameras, and several processors to handle the numerous tasks required. That’s all fixed to an astonishingly strong carbon-fiber frame, home-brewed using a novel molding technique.

i3 Detroit’s tour group got to meet several MAAV team members, check out various early and current hardware versions, and ask tons of questions. As several of our members have robotics and quadrotor experience, there was idea-sharing in both directions.

To demonstrate the stability of the quadrotor’s control system, our guide Jonathan told it to take off and hover at a particular position, and then grabbed one corner of the machine and pulled it several feet out-of-place. It returned immediately to its commanded position and held there, steady as a hummingbird, until commanded to go somewhere else. See the full video of the demonstration here.

IMG_0100After leaving the STPC, half of our group continued on to the day’s second destination, a datacenter by the name of MACC: the Michigan Academic Computing Center. Housing servers and equipment for numerous university departments, it’s a rack-mounted forest of Infiniband cables, storage arrays, and machines with names like “dixiedynamite”. We compared notes about power and cooling, talked about fiber optics and interconnect latency, and hunted down a lone GPS time server.

There are plenty of interesting places in southeast Michigan, and with these field trips, we’re exploring some of them. Stay tuned!
