Red Bull Flugtag

buildscc | 22 Feb 2012 | | projects


Red Bull Flugtag (German: flight day, airshow) is an event owned and operated by Red Bull in which competitors attempt to fly homemade human-powered flying machines. The flying machines are usually launched off a pier about 30 feet (9.1 m) high into the sea (or suitably sized reservoir of water). Most competitors enter for the entertainment value, and the flying machines rarely fly at all. (Stolen from Wikipedia!)

Meeting Minutes for 2012-02-22


Kyle Brogle

  • Project updates…Much was done this weekend!

Dan Gastler

  • The door still runs on the old code. Notice the camera above the table? It gives a live stream (.mpeg 4 video) from the camera outside the door. This was hacked together from an old thinkpad that Danny found, together with work from both Allan and Dan.

Chris Woodall

  • BUILDS bot has spawned a minibot named 12ounce. Made from the casing of an old IR motion sensor, it’s a good start for the BUILDS bot project to get used to coding/ making (working) motor controls.

Monica Gribouski

  • Toby from IS&T came in and taught BUILDS multitouch how to ame polish their acrylic, so further progress is now blocking on the acquistion of new materials.

Chris Woodall

  • BUILDS has a table reserved at the Cambridge Maker Fair (on April 20th). Contact Chris/Kyle if you have any projects that you’d like to contribute.

(KDE) Jeff Crowell

  • The laser arrived for BUILDS drawbot, so work will continue this weekend. Contact Jeff if you’re interested.

George Silvis / Anthony Inzero

  • Many thanks to George and Zero for traveling to Micro-Center and (successfully) building three new BUILDS computers. So sayeth Baron von Computer: if you need something installed on any of the computers, talk to George or Kyle.

Liam Wang

  • VGC is still going, but temporarily blocking on Liam surviving theatre Hell Week. If you’re interested in helping out, contact Liam.

Allan Wirth

  • BUILDS Coding Bee: (Think first annual Python Bee). The acceptable languages are C, Python, and Haskell. The grand prize is a BUILDS ceiling tile with your face on it (to remain in BUILDS). If you have a language that you really want, contact Allan or George.

Dan Gastler

  • Musical Stairs:
    • New goals are to solder on two new jacks and test two new sensors. Work will begin on saturday at 3pm.

Danny Cooper

  • Work on BUILDS document camera is still in progress, but milestones are being blocked by terrible manufacturer documentation.

Chris Woodall

  • Thanks to Ian and his generous typewriter donations, BUILDS typewriter can now begin. Hacking will commence this saturday at 2pm.

Valerie Young

  • Meta Topics:
    • Funds are roughly at 600 of free-use money. If you need funding for your project, contact Valerie for other means (Jim Stone, SAO, etc). For BUILDS officer elections, the format is heading toward having a secret veto ballot (in person, not over email), and having tickets of officer groups as opposed to voting for officers individually.

Chris Woodall

  • If you want to participate in a BUILDS arduino/ soldering workshop, talk to Chris so he can get a rough idea of interest.


Artisan’s Asylum Hovercraft Competition

BUILDS recently participated in the Artisan’s Asylum Hovercraft Design Challenge, which took place from Friday January 27th at 7:30pm to Sunday January 29th at 7:30pm. Upon arrival, teams were given kits containing two brush motors, two servo motors, a radio receiver and transmitter, a hunk of foam, and a plywood plank. After getting a basic rundown on how not to kill themselves with the variety of equipment available at Artisan’s Asylum, the teams got to work.

BUILDS entered two teams: Team McFly, containing Chris Woodall, Ian Felder, Alejandro Bancalari, and Marc Beneck; and The Cult of the Devouring Fan, containing Patrick Erlicher, Rusty Shomberg, Alex Whittemore, and Billy Gulotta. For both teams, Friday night was devoted to planning. The Cult of the Devouring Fan knocked out their designs and left early due to other obligations while McFly stayed up late cutting out the basic outline of the hoverboard in foam. With a double-thick foam base, McFly’s craft was far larger than any of the other teams’.

Saturday morning the members of McFly purchased more supplies and spent the day working. By the end of the day they were the only team with a completely functioning hovercraft, and therefore left early.

The Cult of the Devouring Fan wasn’t faring so well.

“We had really grand designs,” says Patrick Erlicher of their process. Unfortunately, the complex plans to combine lift and steering into one smooth mechanism weren’t possible with their situation: at any one time, they only had one working motor due to burnout of the other, and team members had other commitments and kept dropping in and out. By Sunday morning they were in rough shape: still attempting to optimize their craft but with no real functionality, team member Alex Whittemore was forced to bring in another motor. Things continued to go downhill: a member of the Cult was shipped off to the hospital after an incident with misjudged depth perception and the main fan of their craft, and by 7pm, the race just half an hour away, the craft still didn’t have enough torque to maneuver correctly.

McFly, comparatively, were taking the day easy. Confident about their early working craft from the day before, they arrived late and spent the day decorating their hovercraft. When it came to race time, they were pitted against the other larger crafts. As the race began one team didn’t take off, but McFly and the other craft floated down the track. Approaching the finish, the other craft’s motors burnt out and it crashed, blocking the path for McFly to get through. While fighting their way around it, McFly’s engines burnt out and the race was a scratch. They were able to replace their motor for the second race and was the only craft to take off, but unfortunately burnt out before the finish line again.

Meanwhile, the Cult of the Devouring Fan, running off chicken wings and prayers, decided to completely re-vamp their design half an hour before the race. They changed their propulsion system to push rather than pull air, remounting the rudder, and only tested this new design in the hallway en route to race. The only two crafts to lift off were the Cult’s newly christened “Brogle the Insatiable”, named after the BUILDS president, and Artisan’s Asylum’s own Magic Smoke. The Asylum’s team had a clever cooling method: to keep the motor from burning out, they put the body of the motor in a soda can full of ice cubes. It was a close race in that both crafts were definitely going to finish (many crafts had trouble taking off), but due to Brogle’s speed and the maneuverability it gained from being able to bounce itself out of corners meant that the Cult of the Devouring Fan came in first.

All teams that competed won one month free membership at Artisan’s Asylum, and Brogle the Insatiable remains on display as the winning craft for the next year. BUILDS was extremely impressed with the hospitality and facilities of Artisan’s Asylum and hopes to both compete and work with them again in the future.
