Video Quick Bit: The Best DIY Musical Instruments

Posted on by

The Hackaday Prize is almost over, and soon we’ll know the winners of the greatest hardware competition on the planet. A few weeks ago, we wrapped up the last challenge in the Hackaday Prize, the Musical Instrument Challenge. This is our challenge to build something that goes beyond traditional music instrumentation. Majenta’s back again looking at the coolest projects in the Musical Instrument Challenge in the Hackaday Prize.

We’re old-school hardware hackers here, and when you think about building your own drum machine, there’s really nothing more impressive than building one out of an Atari 2600. That’s what [John Sutley] …read more

The Swiss Army Knife of Audio Synthesis

Posted on by

Thirty years ago, we would be lucky if a computer could play audio. Take a computer from twenty years ago, and you’ll be lucky if it can play an MP3 in real-time. Now, computers can handle hundreds of tracks of CD-quality audio, and microcontrollers are several times more powerful than a desktop computer of the mid-90s. This means, of course, that microcontrollers can do audio very, very well. For his entry to the Hackaday Prize, [Fabien] is capitalizing on this power to create a Swiss Army knife of audio synthesis. It’s called the Noise Nugget, and it’s just what you …read more

Wavetable General MIDI For Everyone

Posted on by

There are only so many ways to generate music with a computer, and by far the most popular method is MIDI. It’s been around for thirty-five years, and you don’t get to be a decades-old standard for no reason. That said, turning MIDI into audio is a pain, but this project in the Musical Instrument Challenge for the Hackaday Prize makes it easy. It’s a Fluxamasynth Module that turns MIDI into something you can hear.

The key to this build is a single chip that takes MIDI data in and spits out audio, according to the 128 general MIDI sounds. …read more

The Incredible Judges Of The Hackaday Prize

Posted on by

The time to enter The Hackaday Prize has ended, but that doesn’t mean we’re done with the world’s greatest hardware competition just yet. Over the past few months, we’ve gotten a sneak peek at over a thousand amazing projects, from Open Hardware to Human Computer Interfaces. This is a contest, though, and to decide the winner, we’re tapping some of the greats in the hardware world to judge these astonishing projects.

Below are just a preview of the judges in this year’s Hackaday Prize. They’ve been busy looking over all of the finalists and on Saturday we’ll announce the winners …read more

The Ultimate MIDI Wind Controller Is The Human Voice

Posted on by

When it comes to music, the human voice is the most incredible instrument. From Tuvan throat singing to sopranos belting out an aria, the human vocal tract has evolved over millions of years to be the greatest musical instrument. We haven’t quite gotten to the point where we can implant autotune in our vocal cords, but this project for the Hackaday Prize aims to be a bridge between singers and instrumentalists. It’s a hands-free instrument that relies on vocal gesture sensing to drive electronic musical instruments.

The act of speaking requires dozens of muscles, and of course no device that …read more

With Grinning Keyboard and Sleek Design, This Synth Shows It All

Posted on by

Stylish! is a wearable music synthesizer that combines slick design with stylus based operation to yield a giant trucker-style belt buckle that can pump out electronic tunes. With a PCB keyboard and LED-surrounded inset speaker that resembles an eyeball over a wide grin, Stylish! certainly has a unique look to it. Other synthesizer designs may have more functions, but certainly not more style.

The unit’s stylus and PCB key interface resemble a Stylophone, but [Tim Trzepacz] has added many sound synthesis features as well as a smooth design and LED feedback, all tied together with battery power and integrated speaker …read more

Chiptunes In An Altoids Tin

Posted on by

For [Dejan]’s entry to the Musical Instrument Challenge in this year’s Hackaday Prize, he’s tapping into some of the great work that has been done over the years to bring bleeps and bloops to the masses. He’s building a drum machine, a bass synth, and an arpeggiator that fits in your pocket, in a handy form factor that fits in an Altoids tin. It’s the FATCAT Altoids Tin Mod Tracker.

This is a simple build meant to fit in an Altoids tin, so you’re not getting a whole lot of hardware here. There’s a battery, there’s a boost circuit, and …read more

Hardware Controllers For Software Effects

Posted on by

There is an interesting multi-effect available for all you musicians out there. It’s the Turnado from Sugar Bytes. It’s a real-time effects unit that takes advantage of a computer’s horsepower to add reverb and ring mods to whatever audio you feed into it. There’s flanger and a phaser. If you feed a drum loop into your computer, there’s a stutter function which means you too can become a Soundcloud rapper.

Unfortunately, this multi-effect runs on a computer. That means you have to deal with the user interface of a desktop or laptop — GUIs, a mouse, and keyboard. Maybe a …read more

Gutters To Gardens: The IoT Rain Barrel

Posted on by

There’s nothing quite like having a garden in your backyard. You get tomatoes with flavor. Fresh herbs are easy. If you’d like to go crazy, you can always grow a gigantic pumpkin. But there’s a problem with gardening: the work. You’ve got to water, and you’ve got to weed. You’ve also got to deal with the thousand ladybugs you bought for a laugh.

For his Hackaday Prize entry, [Kent] has solved at least one of these problems. It’s an Internet of Things rain barrel. It’s designed to be as simple as possible so that anyone can set it up …read more

Looks Like a Glove, Plays Like a Musical Instrument

Posted on by

The GePS is a musical project that shows how important integration work is when it comes to gesture controls. Creators [Cedric Spindler] and [Frederic Robinson] demonstrate how the output of a hand-mounted IMU (Inertial Measurement Unit) and magnetometer can be used to turn motion, gestures, and quick snap movements into musical output. The GePS is designed to have enough repeatability and low enough latency that feedback is practically immediate. As a result, it can be used and played like any other musical instrument that creates sound from physical movements in a predictable way. It’s not unlike a Theremin in that …read more
