May This Balloon Banjo Resonate With You

Most instruments, with maybe the exception of pianos, have consumable parts. Guitars need string changes, bows need rosin, saxophones need reeds. [Co:Creation Lab]’s balloon banjo requires both fishing line and a party balloon, lest it be semi-silent.

If you want to change the resonance, just increase or decrease the amount of air inside the balloon. Neither the balloon nor the strings need tools to adjust, but we might argue that tuning pegs are tools.

The balloon banjo was the result of a design constraint: a parent should be able to build it with their child. To that end, there are no metal screws, no recurring snap-fits in the assembly, and a single, internal, one-time-use snap fit for the adult’s tactile satisfaction. Instead, the balloon banjo uses 3D-printed screws. A six-year-old can turn them with their fingers, and it’s difficult to over-tighten them and strip the plastic threads.

Be sure to check it out in action after the break. If you would rather use extant plastic to make music, the Bottlephone 2.0 is calling.

Exquisite Craftsmanship Elevate Vic’s Creations Above The Rest

This booth was easy to miss at Maker Faire Bay Area 2019 amidst tall professional conference signage erected by adjacent exhibitors. It showcased the work of [Dr. Victor Chaney] who enjoys his day job as a dentist and thus feels no desire to commercialize his inventions — he’s building fun projects for the sake of personal enjoyment which he simply calls Vic’s Creations. Each project is built to his own standards, which are evidently quite high judging by the perfect glossy finish on every custom wood enclosure.

Some of these creations were aligned with his musical interests. The Backpacking Banjo was built around a (well cleaned) cat food can to satisfy the desire for a lightweight instrument he can take camping. His Musical Laser Rainbow Machine (fully documented in Nuts & Volts) was created so little bands formed by independent artists like himself can have a visual light show to go with their live performances. The Music Kaleidoscope is another execution along similar lines, with an LED array whose colors are dictated by music. Venturing outside the world of music, we see a magnetically levitated Castle In The Clouds which also receives power wirelessly to illuminate LEDs

The largest and most complex work on display is an epic electromechanical masterpiece. Par One is a rolling ball sculpture featuring the most convoluted golf course ever. Several more rolling ball sculptures (also called marble machines or marble runs) are on display at Dr. Chaney’s office which must make it the coolest dentist’s lobby ever. The lifelike motions he was able to get from the automatons he built into the sculpture are breathtaking, as you can see below.

Banjo Hero

We’ve posted a plethora of Guitar Hero style hardware hacks, but this one is completely different than the others. Behold, the Banjo hero. This unique controller was constructed from an old banjo and a guitar hero controller. Custom software was then built with custom songs for game play. We really wish we could see it in action. There are a couple videos available for download, but they are just pictures of the build process.

Red Bull Flugtag Portland


Off all the competitions for poorly performing human powered flying machines, the Red Bull Flugtag is one of our favorites. Honestly, it’s the only one we can think of, but that doesn’t mean we’re any less enthusiastic about giving flight to half baked ideas. Today was the Portland round of the international event. Teams have to submit an application for their craft in advance. The vehicle can have a maximum wingspan of 30 feet and a weight with pilot of 450 pounds or less. Power is from muscle or simply gravity. The vehicle also has to be easily retreivable so they can get it out of the water. Judging isn’t just for distance, but for creativity, too.

Flickr users [pdx-kate] and [Jabin] have uploaded images and video from the day: The winner was Team Yakima’s big wheel that flew 62 feet. Second place went to Greased Lightning at 55 feet. Third was the FreeBallin sneaker which you can see in flight here. The People’s Choice award went to the Space Balls Winnebago, which we unfortunately can’t find a very good picture of. You can read more about each individual entry on the results page.

Embedded below is the video of the current US record holder: a banjo that went 155 feet in Nashville. The next US event will be September 6th in Chicago.
