Wheelbarrow Bass Drives A Sound Garden

One of the best things about making music is that it’s so easy to do. There are countless ways to make interesting sounds out of nearly anything if you’re willing to experiment a little bit — just ask anyone who has ever made a guitar out of a cigar box and a broom handle.

[Vicious Squid] dug in to the fertile soil of the garden implement world and cultivated a three-string upright bass with a rich, soulful sound from a familiar workhorse — an aluminium wheelbarrow. Much of the build is made from reclaimed wood, like the solid mahogany neck from an old door frame, and a broom handle.

The bass is constructed arch-top style, meaning that the soundboard — the wood on the front with the f-holes — is a flat piece tacked to curved ribs that span the width of the ‘barrow. A broom handle sound post mounted front to back pushes vibrations from the soundboard to the aluminium body. To round out the agricultural aesthetic, [Vicious Squid] strung it with weed-whacker bass strings, which are no doubt inspired by the use of actual trimmer line.

It’s already plenty loud, but [Vicious Squid] added a piezo pickup for wheeling it into the recording studio. Slap your way past the break to hear a little ditty.

Are your instrument-building skills at the sapling stage? Start with something simpler, like a sliding rubber bandolin.

Radio Controlled Wheelbarrows Tear Up The Track

The wheelbarrow is a trusty companion to the gardening set, helping move heavy loads to and fro. [James Bruton] has an active imagination however, deciding to build a motorized racing barrow, and challenging his friends to do the same (Youtube link, embedded below).

[James] went with a straightforward design, fitting two wheels to the rear, and powering them with brushless inrunner motors. The original front wheel was then fitted with a caster mechanism to allow the barrow to be skid steered. A pair of lithium polymer batteries provide the juice, with [James] using VESC skateboard ESCs to run the motors. The whole contraption is radio controlled, with an Arduino handling the mixing for steering duties.

The motorized barrow performed well against its competition, a propeller-powered barrow from [Tom Stanton] and a leaf-blower propelled barrow from [Ivan Miranda]. Inclement weather did cause some issues, but the trio were kind enough to treat us to a destruction derby with their racing machines.

You may be familiar with [James]’ earlier work on the openDog project. Video after the break.

Electric Wheelbarrow Makes Hauling Big Loads Easier

Gardening involves a depressing amount of physical activity: haul this over here, dump it there and then cover it with this. Things like wheelbarrows are still damn hard work, especially for people like who are somewhat physically compromised. That’s why we love this build from [Karl Gesslein]. He usually makes electronic bikes, adding motors to bicycles to roam the streets faster. But this time he applied his expertise to a wheelbarrow. He added a 3000W motor to the wheelbarrow, which drives the front wheel when triggered by the accelerator on the handle.

Our Gunpowder And Tea Came From China, Why Didn’t We Copy Their Wheelbarrows?

My dad's low-loader barrow. You would not believe how useful it is.
My dad’s low-loader barrow. You would not believe how useful it is.

Everyone must have a few things that are emotive of their childhood, perhaps a sight, a sound, or a smell. For me, growing up as I did on a small British organic farm in the 1970s, my emotive things are the smell of rain hitting parched earth, or of the slightly sulphurous diesel exhaust from a clapped-out Fordson Major tractor. And wheelbarrows, strangely. My dad, you see, is both a blacksmith by trade and an inveterate experimenter in the field of handcarts and barrows. A small self-sufficient farm generates a huge range of different loads that need carrying around, and he fashioned a variety of inventive contraptions for the purpose. Of most use are his oversized builder’s barrows with a full-size van wheel at the front and able to cross the bumpiest of ground, but other highlights included the low-loading barrow for shifting the heaviest one-piece loads, or the two-wheeler for very long objects.

As you might expect then, I have an eye for a barrow, as I’ve pushed a few in my time. So when I read about how traditional Chinese barrows are constructed, they caught my attention and I had to ask: why don’t we do it that way?

Hackaday Links: Sunday, August 4th, 2013

[Craig Turner] shows that simplicity can be surprisingly interesting. He connected up different colors of blinking LEDs in a grid. There’s no controller, but the startup voltage differences between colors make for some neat patterns with zero effort.

Remember the 3D printed gun? How about a 3D printed rifle! [Thanks Anonymous via Reason]

While we’re on the topic of 3D printing, here’s a design to straighten out your filament.

It takesĀ four really big propellers to get an ostrich off the ground. This quadcopter’s a bit too feathery for us, but we still couldn’t stop laughing.

This Kinect sign language translator looks pretty amazing. It puts the Kinect on a motorized gimbal so that it can better follow the signer. We just had a bit of trouble with translation since the sound and text are both in Hebrew. This probably should have been a standalone feature otherwise.

Lawnbot400 Saves Wheelbarrow Trips

We may be good at soldering but when it comes to hauling topsoil our scrawny arms quiver. [Johndavid400] did the smart thing here by letting the machine do all the work. Instead of hauling an entire truckload of dirt across the yard one wheelbarrow at a time, he built a shelf on the top of his Lawnbot400. We saw this lawnmower Arduino-powered, remote control mower back in November. The addition of its ability to handle some of the manual labor makes it the perfect backyard hack.
