Wonderful Sculptural Circuits hide Interactive Synthesizers

Posted on by

When it rains, it pours (wonderful electronic sculpture!). The last time we posted about freeform circuit sculptures there were a few eye-catching comments mentioning other fine examples of the craft. One such artist is [Eirik Brandal], who has a large selection of electronic sculptures. Frankly, we’re in love.

A common theme of [Eirik]’s work is that each piece is a functional synthesizer or a component piece of a larger one. For instance, when installed the ihscale series uses PIR sensors to react together to motion in different quadrants of a room. And the es #17 – #19 pieces use ESP8266’s …read more

Analog Synth, But In Cello Form

Posted on by

For one reason or another, electronic synthesizing musical instruments are mostly based around the keyboard. Sure, you’ve got the theremin and other oddities, but VCAs and VCFs are mostly the domain of keyboard-style instruments, and have been for decades. That’s a shame, because the user interface of an instrument has a great deal to do with the repertoire of that instrument. Case in point: [jaromir]’s entry for the Hackaday Prize. It’s an electronic analog synth, in cello form. There’s no reason something like this couldn’t have been built in the 60s, and we’re shocked it wasn’t.

Instead of an electrified …read more

The Portable, Digital, Visual Theremin

Posted on by

The theremin is, for some reason, what people think of first when they think of electronic musical instruments. Maybe that’s because it was arguably the first purely electronic musical instrument, or because there’s no mechanical analog to something that makes sound simply by waving your hand over it. This project takes that idea and cranks it up to eleven. It’s a portable synthesizer that’s controlled by IR reflectors. Just wave your hand in front of it, and that’s what pitch is going to sound.

The audio hardware for this synth is, like so many winners in the Musical Instrument Challenge …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

Elegant Drum Machine from Teensy

Posted on by

Playing the drums is pretty hard, especially for the uncoordinated. Doing four things at the same time, all while keeping an even tempo, isn’t reasonable for most of us. Rather than hiring a drummer for your band who is well versed in this art, though, you might opt instead to outsource this job to a machine instead. It’s cheaper and also less likely to result in spontaneous combustion.

This drum machine is actually a MIDI Euclidean sequencer. Euclidean rhythms are interesting in their own regard, but the basics are that a common denominator between two beats is found in order …read more

Can You Build An Open Source Pocket Operator?

Posted on by

Toys are now musical instruments. Or we’ll just say musical instruments are now toys. You can probably ascribe this recent phenomenon to Frooty Loops or whatever software the kids are using these days, but the truth is that it’s never been easier to lay down a beat. Just press the buttons on a pocket-sized computer.

One of the best examples of the playification of musical instruments is Pocket Operators from Teenage Engineering. They’re remarkable pieces of hardware, and really just a custom segment LCD and a few buttons. They also sound great and you can play real music with them. …read more

Synthesizing Mother Nature’s Sounds Like You’ve Never Seen Before

Posted on by

We’ve all heard the range of sounds to be made electronically from mostly discrete components, but what [Kelly Heaton] has achieved with her many experiments is a whole other world, the world of nature to be exact. Her seemingly chaotic circuits create a nighttime symphony of frogs, crickets, and katydids, and a pleasant stroll through her Hackaday.io logs makes how she does it crystal clear and is surely as delightful as taking a nocturnal stroll through her Virginia countryside.

The visual and aural sensations of the video below will surely tempt you further, but in case it doesn’t, here’s a …read more

Fail of the Week: How Not to Design an RF Signal Generator

Posted on by

We usually reserve the honor of Fail of the Week for one of us – someone laboring at the bench who just couldn’t get it together, or perhaps someone who came perilously close to winning a Darwin Award. We generally don’t highlight commercial products in FotW, but in the case of this substandard RF signal generator, we’ll make an exception.

We suppose the fail-badge could be pinned on [electronupdate] for this one in a way; after all, he did shell out $200 for the RF Explorer signal generator, which touts coverage from 24 MHz to 6 GHz. But in true …read more

OTTO: A Pi Based Open Source Music Production Box

Posted on by

Want an open source portable synth workstation that won’t break the bank? Check out OTTO. [Topisani] started OTTO as a clone of the well-known Teenage Engineering OP-1. However, soon [Topisani] decided to branch away from simply cloning the OP-1 — instead, they’re taking a lot of inspiration from it in terms of form factor, but the UI will eventually be quite different.

On the hardware side, the heart of the OTTO is a Raspberry Pi 3. The all-important audio interface is a Fe-Pi Audio Z V2, though a USB interface can be used. The 48 switches and four rotary encoders …read more

Shell Script Synthesizer Knocks Your SoX Off

Posted on by

Sound eXchange, or SoX, the “Swiss Army knife of audio manipulation” has been around for as long as the Linux kernel, and in case you’re not familiar with it, is a command line tool to play, record, edit, generate, and process audio files. [porkostomus] was especially interested about the generating part, and wrote a little shell script that utilizes SoX’s built-in synthesizer to compose 8-bit style music.

The script comes with a simple yet straightforward user interface to record the lead and bass parts into a text file, and play them back later on. Notes from C2 to C5 are …read more
