As part of the recent OMGWTFBBQ festivities9, a contest was held, pitting the forces of gravity against the weight of cold hard cash (pennies, to be specific). The goal of the contest was to use soda straws to support as much currency as possible in as high of a position as possible, thus racking up the most “inch-cents” of score.
As it turns out, we ended up going to “foot-dollars” and using weights that weren’t exactly copper, given the engineering of some of the entries. Check out the results below.
|Stephanie & Cait||8.25||2898||23908.5||19.92|
|John & Don||11.25||271.5||3054.38||2.55|
|Claire & Dad||7.5||271.5||2036.25||1.70|
|Jess & Company||14.25||45||641.25||0.53|
|Patrick & Travis||19.375||14||271.25||0.23|
|Ben & Dave||11.5||0||0||0|
RedBull Creation challenge entry. It’s a brain-wave game. The players stand on opposite sides with wireless headsets that measure brain waves. One of them presses the big red button on the back, and then as they focus the power of their minds, the arm responds to their brain wave readings, and moves back and forth according to who is focusing best. After 10 seconds the Bullduino (visible at the front in the window) checks whether the pointer is in one of the green scoring zones. If it is still in the yellow zone, it’s a tie and it just returns to center. If it is in one of the green zones the player on that side is the loser, and the ball sprays that player.
After a run up of making throughout the week, the bridge competition began at the Makery last Sunday to test the designs of our participants. In all, there were 9 entries (some last minute).
In short, the rules:
Bridge:May contain only balsa wood and Titebond 2 wood glue.Must fit within a 50 x 20 x 10 cm rectangular volume.May not contain more than 6oz of glue by wet volume.Must have a smoothish road deck no less than 6cm in width.- suitable for a HotWheels-style car to easily roll overDeck ends must contact the upper surface of the test rig support planks.Deck must have no more than a 10% grade (where grade = 100 * (rise/run))Deck must accommodate the load plate.Some part of the load plate must fall across the midpoint of the span.There are no limits on construction tools or technique.Scoring:The load plate is 10 x 5 x 1 cm, and has a loading hook extending from the center of the bottom surface which requires 1 cm annular clearance through and below the bridge deck.Bridges will be loaded progressively (w/ minimum shock load), starting at 5kg and progressing in 1Kg increments to 10Kg.Upon reaching the maximum load, the bridge must hold for 1 minute.- Disputes as to whether a bridge ‘held’ will be resolved by voteBridges that fail will be ranked by the weight carried without failure and bridge mass.Bridges that do not fail will be ranked by the mass of the bridge.Testing:The open span between the support planks is 30cm.The open span is between rectangular, fixed, smooth, level, coplanar planks with a thickness of ~2cm.The bridge may touch the top or inner surfaces of the supporting planks, but may not touch any other surface, nor be affixed to any surface.The load plate will support a wire or rod from which the test load will be suspended.
By now you may have worked out that there is a category in the results called “Fail Weight.” Well, we at OMG like to test to the limits of design. Also, we’re all about 8 years old at heart and like to break things, filming the results in slow motion video if at all possible. So, without further ado…every last bridge getting destroyed/max tested to sexy music:
Join us for our next competition, to be held this Sunday! See the forum for details.
Last Sunday (April 1st) was the first Omaha Maker Group Egg Drop. The competition was much in the same style as the Nerf Gun Mod Contest run last fall; This competition had a lower entry barrier, and thus far greater turnout, with 10 total entries (Eric entered twice). All the eggs survived the drop, but Stephanie was the big winner, with a score that bested the next entrant by a factor of 4. Click through for full results, and a little high-speed video, thanks to Ben. Continue reading
Last night, the Makery hosted a Nerf Gun Mod contest, previously announced here. We had 5 total entrants, after a few people had things come up at the last minute, and about twice that many spectators.
Only Brandon and Eric made an attempt in this category; Brandon did a functional “pseudo-steampunk” mod (with an extended brass barrel and integrated laser sight), while Eric gave his Nightfinder a complete color revamp using Sharpie markers (Which did come off on his hands). Eric won almost unanimously, earning him an extra 10% in the distance competition.
The accuracy contest was run next, in a series of 8 rounds, with a point going to the entrant who could hit a whiteboard (At about 15 feet) closest to the center mark. The entrant with the most points won this category. The contest itself came down to a shootout between Brandon and Dave, (2.5 points each) with Brandon emerging victorious. Eric (2 pts) and Kevin (1 pt).
This contest measured total distance to rest, thereby including any beneficial or harmful rolling or tumbling that a dart did. A slight accuracy component was involved, in that if a dart went more than 75 feet or so, it had to clear a 5 foot wide doorway. The low ceiling also proved challenging to some contestants, as it limited the amount that a dart could be arced.
Distance was scored as “best of 8 darts”, with each entrant shooting all 8 in succession. Brandon’s was the only dart to clear the doorway, making him the winner. A few darts bounced off the wall, though. Eric’s 10% bonus (2.2 paces, very scientific) was enough to propel him into 3rd place over Dave, leaving the results Brandon, Kevin, Eric, Dave, Patrick.
Overall, Brandon was the supreme winner, having taken first place in both categories. Even with a smaller-than-expected field, everyone involved had a great time. Thanks to all involved for making last night a success! A few photos from the event are below.
