Copper Foil Makes Music–With a Little Help

Posted on by

Craft stores are often the source of odd inspiration. In the stained glass section, we’ve seen the copper foil, and even used it to prototype some RF circuits on the tops of shoeboxes. However, we could never get a good method for connecting ICs to the relatively thick foil. [Bryan Cera] did it though. His paperSynth uses some paper and cardboard for a substrate, copper foil, and an ATtiny CPU to make music. You can see the device in operation in the video, below.

The copper foil is sticky and it isn’t conductive on the back, so anywhere the foil …read more

The 35 Year Music Synthesizer that Spawned Chiptune

Posted on by

If you are a certain age, MOS6581 either means nothing to you, or it is a track from Carbon Based Lifeforms. However, if you were a Commodore computer fan 35 years ago, it was a MOS Technologies SID (Sound Interface Device). Think of it as a sound “card” for the computers of the day. Some would say that the chip — the power behind the Commodore 64’s sound system — was the sound card of its day. Compared to its contemporaries it had more in common with high-end electronic keyboards.

The Conversation has a great write up about how the …read more

A Mess Of Wires Turned Into An Analog Synth

Posted on by

Over on YouTube, [GumpherDM3] built one of the greatest musical projects we’ve seen in a long time. It’s an analog synthesizer that is one of a kind. It’s going to stay one of a kind, too: no one would ever want to copy this mess of wires and perfboard that was successfully turned into a complete musical instrument.

The design of this synth is what you would expect from something that draws its inspiration from semimodular synths such as the Minimoog and Korg MS20. There are four VCOs on this synth, two audio and two used for the LFOs. A …read more

It’s a Synthesizer. It’s a Violin. It’s a Modulin

Posted on by

It sounds a little like a Theremin and looks a lot like the contents of your scrap bin. But it’s a unique musical instrument called a modulin, and after a few teasers we finally have some details on how it was built.

Making music with marbles is how we first heard of [Martin] of the Swedish music group Wintergatan. He seems as passionate about making his own instruments as he is about the music itself, and we like that. The last time we saw one of his builds was this concert-ready music box, which he accompanied with an instrument he …read more

A Six-Voice Synth Built On The Raspberry Pi

Posted on by

Over the last few decades, audio synthesizers have been less and less real hardware and more and more emulations in software. Now that we have tiny powerful computers that merely sip down the watts, what’s the obvious conclusion? A six-voice polyphonic synthesizer built around the Raspberry Pi.

The exquisitely named ‘S³-6R’ synthesizer is a six-voice phase modulation synthesizer that outputs very high resolution (24-bit and 96 kHz) audio. It’s the product of R-MONO Lab, who have displayed interesting musical devices such as a recorder-based pipe organ in the past. This build is a bit more complex, offering up some amazing …read more

Sync Your Pocket Synth with Ableton

Posted on by

The Teenage Engineering Pocket Operators are highly popular devices — pocket-sized synthesizers packed full of exciting sounds and rhythmic options. They’re also remarkably affordable. However, this comes at a cost — they don’t feature MIDI connectivity, so it can be difficult to integrate them into a bigger digital music setup. Never fear, little-scale’s got your back. This Max patch allows you to synchronize an Ableton Link network to your Pocket Operators.

little-scale’s trademark is creating useful software and hardware devices using cheap, off-the-shelf hardware wherever possible. The trick here is a simple Max patch combined with a $2 USB soundcard …read more

Building A Wavetable Synth

Posted on by

Every semester at one of [Bruce Land]’s electronics labs at Cornell, students team up, and pitch a few ideas on what they’d like to build for the final project. Invariably, the students will pick what they think is cool. The only thing we know about [Ian], [Joval] and [Balazs] is that one of them is a synth head. How do we know this? They built a programmable, sequenced, wavetable synthesizer for their final project in ECE4760.

First things first — what’s a wavetable synthesizer? It’s not adding, subtracting, and modulating sine, triangle, and square waves. That, we assume, is the …read more

MIDI DAC for Vintage Synth Hacks

Posted on by

A lot of classic synthesizers rely on analog control voltages to vary parameters; this is a problem for the modern musician who may want to integrate such hardware with a MIDI setup. For just this problem, [little-scale] has built a MIDI-controllable DAC for generating control voltages.

It’s a simple enough build – a Teensy 2 is used to speak USB MIDI to a laptop. This allows the DAC to be used with just about any modern MIDI capable software. The Teensy then controls a Microchip MCP4922 over SPI to generate the requisite control voltages. [little-scale]’s video covers the basic assembly …read more
