Workshop: Build a Light-Controlled Oscillator

On Saturday the 17th May at 1pm we will be running a workshop at the Audio Foundation. In this workshop you will be provided with a circuit-board, electronic components, and guidance necessary to build an oscillator whose pitch and volume are controlled by light. You can play this instrument theremin-style by moving your hands near the light-sensors, or put it in moving shadows or near flashing lights for automatic control. The circuit-board is specially designed to fit into a tin can.

This workshop is suitable for beginners. We can teach you how to solder.
Only $40 including materials! Get in touch right now if you want to participate, space is limited. Email kraus [AT] kraus [dot] [co] [dot] [nz]

Thanks, see you soon!?

Alco-phono

Idea for a new instrument:

You can get these alcohol sensors

mq303and I was thinking, an idea for an instrument would be a thing where you had to blow into a tube and the sensor checks how much alcohol is in your breath. If you haven’t had enough to drink the instrument makes no sound. Keep drinking and try again, now you’re drunk enough and it starts to make sound.

Handmade Electronic Music

The book that inspired the Musical Electronics Library: “Handmade Electronic Music” by Nicolas Collins.

This book is SO GREAT. It assumes no technical knowledge whatsoever. It starts out with a lot of fun projects that don’t even require soldering, such as playing the insides of a transistor radio with your fingers. There are so many good ideas here, like the Matrix Mixer, which doesn’t require power, and is perfect for turning a pile of innocuous guitar pedals into a complex, chaotic feedback oscillator. Most of the things in the book are analogue sound generators, but there are also ideas for computer controllers, eg. using hacked joysticks, and some video circuits. The emphasis is on adventurous, bold hacking and circuit bending, with a generous helping of from-scratch DIY electronics as well. The tone is always encouraging, which makes it a pleasure to read. There is a minimum of theory.

The second edition includes a DVD, which has video tutorials:

audio examples, and, best of all, a long series of 1-minute video clips submitted by hardware hackers around the world, showing off their amazing creations:

Nicolas Collins has generously shared the pdf file of his original workshop manual Hardware Hacking, upon which Handmade Electronic Music is based.

MEL prehistory 2

So after having the idea for the library I had to think about how to go about it. Initially my rough plan was to build things myself, using my own money, and store the collection at my house. I spent April and May 2013 building the first dozen circuits for the collection. These were mostly housed in VHS tape boxes, because of these reasons that I wrote about here.

Having a limited budget and wanting to build things as quickly as possible I focused on relatively cheap, simple circuits. The average cost of parts for each box was about $20. I built mainly sound-processing rather than sound-generating stuff, because it’s easier. I built a phaser, a ring modulator, a pitch shifter, some distortions, an oscillator, two noise makers, and a matrix mixer. I did most of the work on a chaotic drum machine, then I got burned out and didn’t make anything for the rest of the year. But I still thought the library was a good idea, and so did everyone I talked to. At the start of this year I met Rob Carter and Brett Ryan, who were both very supportive and wanted to help build stuff for the library. Which brings us up to date. End of prehistory period.

MEL prehistory 1

I am Pat Kraus. I’ve been doing electronics for about 8 or 9 years. I taught myself how to solder in about 2005, and since then i’ve built a bunch of guitar pedals, battery-powered synth boxes, and, most recently, a Serge modular synthesizer. The idea for the Musical Electronics Library came to me in March 2013 when I was reading Nicolas Collins’ excellent book “Handmade Electronic Music”. There are a lot of cool ideas in that book, and I wanted to try them out, but I was faced with a problem that had bothered me for a long time: deciding what to build. There are so many nice electronics projects I’d like to make — there are a million on the internet — but of course I’ve only got limited time and money. And it’s common to encounter something that’s electronically or sonically very interesting, but which I wouldn’t actually use that much myself. So I never get around to making it.

One solution is to build stuff for sale. Then you get to make things you might not use yourself, but that someone else will. I have done this in the past, but I found it stressful, and I’m not very motivated to make money, so I never really got into it that much. Besides, there’s not a lot of demand for more esoteric, unusual gear. When I was reading Nic Collins’ book I realised that a better solution for me would be to make a lot of stuff and then lend it out, like a library. That way I could build whatever took my fancy, and someone would be bound to find a use for it. This seemed like a good way to combine my interest in electronics and music with a desire to serve my community.

What is the point of this website?

The point of this website is mainly to let you know what’s happening at MEL. We’ll also tell you what’s in the collection and how to use it. We want to encourage DIY electronics as much as possible, so we’ll also post technical information about what we’ve built, to help you to make things for yourself.

The other major goal of the website is to document the history of MEL. This is partly to provide a resource for future musical electronics librarians. If you’re thinking of establishing a similar project we’d like to help you as much as we can. We’ll write about our philosophy and ideas, and why we’ve proceeded as we have, so that you can learn what’s worked for us.
