Wherever you live, you can enjoy the DIY and open hardware inventions coming out of Texas. Or, as the famous song goes: “That’s right, you’re not from Texas / Texas wants you anyway.”

Austin, Texas may be associated with the strum of guitars. But it’s also populated by some of our favorite electronic music hardware inventors on the planet, led by the likes of Bleep Labs, 4ms, Eric Archer, and more. They’ve taken the idea of a “Handmade Music” and come up with the best formula for building a community around DIY hardware I’ve seen yet:

1. Get beginners – even if they’ve never soldered before – making noises with a beginning kit workshop.
2. Do an advanced workshop that pushes the envelope with new hardware.
3. Turn that noise into a performance/party: i.e., “After all the kits were built, we plugged in to the PA and partied until the amp overheated.”
4. Provide your specs and software freely.
5. Make a kit available for people to buy.

Notice that it’s possible to make “free hardware” (open sourcing part or all of the code, publishing specs and circuits) and still sell a product. And it’s possible to act locally (workshops in Austin), and sell globally (sharing documentation online, and shipping kits everywhere else).

And notice that it’s possible to make events beginner-friendly. In fact, this isn’t just to teach experienced musicians how to solder. I find that many people who are too shy to make music via traditional means find there’s a freedom to a glitchy, blippy electronic thing that makes noise. After all, through the ages music was never intended to be exclusively the domain of professional specialists.

Here’s the latest on their activities – and a chance to meet the hardware that has come out of their series.

First, let’s meet the devices:

Meet the Beasties

Thingamagoop 2

Bleep Labs’ Thingamagoop seems as much electronic creature as electronic instrument; its sounds seem like the vocalizations of an alien and, yes, it’s darned cute. The new Thingamagoop 2 is more usable (easier-to-access battery), sounds better, and has more features. But it’s also more open in every way. CV in and out lets it interface with analog gear. A programmer jack lets you reprogram it with your Arduino, if you so choose (the Arduino isn’t required, but it does let you reprogram the sounds on your Thingamagoop). And now the sonic effects — sample and hold, arpeggios, noise, and bit crush — all use open-sourced code. That makes what was already an ingenious soundmaker more open to hacking by advanced users.

The Thingamagoop 2 debuted to the world at Austin’s Handmade Music. Now, perhaps we need some hack sessions to get people working on reprogramming this and other sonic oddities.

I expect to get one of these soon, so expect a hands-on.

Nebulophone

Nebulophone is a coming kit that builds on the Arduino platform to create a playable, DIY Stylophone-style instrument. Having debuted at Handmade Music Austin #4, the instrument features “adjustable waveforms, a light controlled analog filter, LFO, and arpeggiator that can be clocked over IR.” Yes, you read that last bit right: it’s all part of the new wireless, infrared sync revolution these guys are leading.

Official site has code, schematics, instructions – so you can actually make your own – plus sound and advance info on the coming kit. I expect a video and more on the kit soon.

SimSam

The SimSam is a noisy, glitchtastic product.

It’s also the subject of a beginners’ workshop, a chance to get people working with electronics for the very first time.

And its cost – a tiny $8 in parts.

It’s also a brilliant use of the ATTINY85, an ultra-compact, 8-pin AVR chip. (AVR chips also live at the heart of the Arduino platform.)

And the SimSam debuted at – you guessed it – a workshop at Handmade Music Austin #4.

Tons of info and everything you need to build your own:

There are actually some details that could use improving, so have a look and see if you can do an updated version.

Autonomous Bassline Generator + Andromeda Space Rocker + MIDI-IR Sync

The Autonomous Bassline Generator…

…can sync up with drum modules like this Andromeda Mk-4 by Eric Archer:

…and sync together via infrared, wirelessly, connecting to each other or slaving to a MIDI clock signal generated by Wooster Audio’s MIDI-IR.

Together, you get the Andromeda Space Rockers: a whole little galaxy of wirelessly-synced sonic gadgets. And all of the above are available as kits, so you can sooth your soul by assembling them yourself.

The creators have debuted and jammed with these gadgets through Handmade Music, and presented workshops on the technologies and concepts that underly their creation.

Arduino, Sound Libraries, and Resources

I asked Dr. Bleep himself (John-Mike) about what resources might be useful for working with the Arduino platform (and similar architectures) and sound. The main secret is, use Pulse Width Modulation to accomplish sounds with a minimum of code:

Here are a few of the pages I used when designing the code for it:

http://little-scale.blogspot.com/ is a fantastic source for “Oh man why didn’t i do that/ this guy is incredible!” projects.

I’m also not the first to mate the stylophone with arduino

The two biggest/ earliest arduino synths were :

One difference with the Nebulophone is that it is very low part count. No multipexers or DACs. Just PWM out to an two opamp analog filter. This does limit the number of keys and controls but makes for a tiny, simple pcb.

Handmade Music Austin, in Videos

How do these events go down? Here’s a look at some of the sonic mayhem.

Handmade #4 lacks a video, but we’ll watch for #5 when it happens.

The next Handmade Music Austin is on February 28. Details aren’t up yet, but I’m told you can expect an advanced workshop on building a digital delay by Nathan/Wooster Audio, plus a simple, light-controlled noisemaker for beginners. Stay tuned to:

Autonomous bassline generators? Wireless, modular, infrared sync? Tiny drum machines networking together? Welcome to Texas, and the minds of Eric Archer, Bleep Labs, 4ms Pedals, the Church of the Friendly Ghost, and Andromeda Space Rockers.

One look at a floor full of blinking circuits, and most ladies and gentleman might assume they’ve stumbled upon some alien technology. “Imagine the things we could learn from this civilization – advancements far beyond our own,” as the stock line from sci fi goes. “Man and woman are not meant to learn such things. You’re meddling in things beyond your comprehension.”

In other words, you couldn’t build something like this, right?

Or could you?

In Austin, Texas, Eric, Dann, and Dr. Bleep are launching a new Handmade Music series, kicking it off with kits and classes so that anyone – including beginners – can start building stuff. For the 101 crowd, there’s a free beginner class even if you’ve never touched a soldering iron, so you can build your own analog drum. “I’m no n00b,” you say, “impress me.” Sure – the “upper division” gets to talk more advanced synth design and walks through the full-blown modular, networkable kit.

At the end of it all is an open jam and featured performance.

If you’re anywhere near Austin, Texas – or can find a bargain plane fare – you’ll want to clear your calendar for October 18!

Full Event Details, October 18 Handmade Music in Austin [Handmade Music @noisepages]

That’s just the first of more events to come, so stay glued to the Handmade Music site for events in Austin, New York, Portugal, Germany, and beyond.

“That’s right / you’re not from Texas / Texas wants you anyway.” For those of us in New York, Lisbon, Rio, Sydney, and Jakarta, there’s still hope. The kits will be online, and I”m looking at ways of putting together a full Handmade Music curriculum of projects online for all of us on the site we’re developing this fall, noisepages – ideas welcome.

I certainly didn’t expect to get deep into these geekier topics in high school while I was busily trying to fail Calculus and screw up science lab results in ways that baffled my teachers. But it’s a glorious age we live in, in which we get to assimilate alien technology as our own. Stay tuned.

Cybernetics is poised to make a comeback. The theory is, everything from electronic circuits to plants and animals can be understood in terms of feedback loops, as organisms – mechanical or organic – respond to input from their surroundings. The father of modern cybernetics, MIT mathematician Norbert Weiner, was inspired by working on the guidance systems of missiles. His writing was picked up Louis and Bebe Barron, informing their organism-like sonic circuits, as used in the film Forbidden Planet. The word cybernetic itself comes from Plato. Plato was talking about human self-governance. But designed with cybernetic ideas in mind, technology, too, becomes self-governing and autonomous – and the sonic circuits, too.

Young designers like Eric Archer are to me the newest continuation of work like the Barrons’. Inside his lab, Eric and others are creating hardware that behaves like intelligent life. In the video at top, four tiny drum machines, equipped with insect-like brains and reflexes, network together wirelessly over infrared, responding to light by way of photocells. These tiny devices form a colonial consciousness.

Eric may be a mad scientist, but he isn’t keeping his work secret or proprietary. He’s sharing the tools, sharing his methods, and with a whole growing crew of sonic DIYers in Austin, Texas, inviting anyone to join the revolution under the banner of the Handmade Music series. (More on the upcoming event shortly.) If you’re not from Texas, a lot of this documentation is also appearing online.

Here are more of the creations, plus the simple but powerful circuit that makes it all happen.

And yes, there’s a lot of potential to wireless IR sync.

The drums have names:

Drum Machines (Eric Archer)
ASR mk I “pops”: two analog damped sine oscillators with photocell pitch control, 16 presets
ASR mk II “snappy”: analog white noise, photocell controlled filter, envelope + VCA, 16 presets
ASR mk III “twiki”: photocell tuned analog osc, photocell tuned LPF, envelope + VCA, programmable
ASR mk IV “boomer”: analog damped sine oscillator, long decay, photocell pitch envelope, programmable

But drum machines are just the beginning of what could eventually be wirelessly synced. First up, this autonomous bassline generator, created by 4ms Pedals

The Autonomous Bassline Generator creates deterministic bassline patterns in a sci-fi retro sound by generating melodies on the fly, based on a knob. It’s just an AVR (attiny44) chip doing all the work, plus an opamp to act as the filter (photocell). The blue button is Tap Tempo, or if you hold it down for 1 second, it syncs up to the pulses on the IR receiver (this lets you beat-sync multiple Andromeda Space Rocker modules). The red button lets you edit a single note in the melody. Pulse-width modulation is currently pre-set to a certain envelope, but that will become user-controllable soon!

Part of the “Andromeda Space Rockers” series of modules, see www.ericarcher.net for drum modules.

The 6-pin header board dangling to the right is an ISP header. Totally hackable!

“Ah,” you say. “But I have computers and things. I don’t just want a bunch of little drum machines running around my studio like so many electronic beetles while I furiously tap my tap tempo in Ableton. Can’t I sync thing up?”

Yes. Yes, you can. There’s already a MIDI-to-IR prototype in the works.

Four analog drum machines are synchronized with a desktop computer running Logic. Logic is playing a loop with TR808 samples. MIDI timecode from Logic is converted to IR Sync with a PIC microcontroller. The PIC flashes an infrared LED, providing wireless clock to a chain of analog drum modules. Each drum module has an onboard sequencer, analog sound generator, and IR Sync repeater. At the end of the video, the tempo is increased to almost 3000 BPM. In a separate test, the system played OK at 1000 BPM. Of course this tempo is ridiculous but it is a nice “torture test” of Nathan’s PIC code.

PIC stuff: Nathan Wooster
drum machines: Eric Archer

Our friends at Bleep Labs also have projects in the works.

Eric and 4ms have contributed the circuits at the heart of this.

This simple circuit handles infrared clock networking. (Click for the full circuit.) I’m assuming you know how to read this; we may have to put together an actual how-to tutorial for those new to electronics, too.

And 4ms has a version for interfacing with microcontrollers.

The Barrons would be proud.
