State Inter State
Recorded improvisation: 19’23 Hardware Components: Scott Petersen/Ethan Bernard: Custom HEF4046BP audio feedback circuit Koma Elektronik: Field Kit FX Korg: Delay Monotron Technical description: This performance was accomplished through the slow rotation of a single potentiometer (one of six) that changed the internal feedback relationship between the three oscillators of the custom circuit. The knob was…

Read MoreFun with the Wien Bridge Oscillator
To the fledgling electronics enthusiast who has just enough knowledge of electronic music theory to be dangerous, it makes sense that the simplest tone, the sine tone, should be the simplest/easiest to construct in the analog electronics domain. Of course, this is not the case. While geometrically simple to describe, the sine tone is not…
Read MoreMake Testing Speakers for Free**
Required Parts: 1-2 8 ohm speakers an enclosure (cardboard box, tea tin, coffee can, etc.) insulation (cotton, an old shirt, the hair you get from your pet when using the Furminator.) wire glue ( any will do, but… I cannot recommend a hot glue gun enough. see below) alligator clips (deluxe version) or just some…
Read MoreSparkfun Amplifier Kit (and Power Supply Solution)
The Sparkfun STA540 amplifier kit is a cool, fun to put together amplifier kit that employs the STA540 amplifier chip at the core of the device. The chip itself is a 4-channel AB amplifier chip that can be employed in a number of ways depending on the circuit configuration. The kit is really easy to…
Read MoreIBeam Laser Show (2011)
It has been almost five months since MuCo performed for the 2nd time at Ibeam and for one reason or another the recording has sadly sat neglected on a hard drive since then. I finally dug it out, mixed the tracks together (output of kane + scacinto) and here it is for your listening pleasure.…
Read MoreElectronic Music from “How Things Work” c.1970
On a recent outing to a local bookshop I encountered a 4 volume set of books titled “How Things Work.” It is a wonderful compendium of knowledge in simple but not simplistic language with really great illustrations. The four volumes cover everything from knitting to jet engines. Naturally what caught my eye were all of…
Read MoreXbee: Information and Resources
The XBee RF radio is certainly not new technology, but it remains a tried-and-true means of communicating with microcontrollers in DIY electronic projects. For those of you unfamiliar with the XBee, it is an RF radio module that can be attached to a circuit via a breakout-board and used to communicate wirelessly with that circuit,…
Read MoreAnalog Ring Modulation Circuit
[youtube=http://www.youtube.com/watch?v=kc5JLWrVEQg&hl=en_US&fs=1] Above is a video and below are some pictures of a simple ring mod circuit I whipped up last night. The circuit is the classic circuit, and I’m simply running two oscillators from a hex schmidt 6-oscillator IC through the circuit as the carrier and modulator. The frequencies of the hex schmidt are being…
Read MoreIntroducing The Little Princess!
What was once the hideous DJ Crappy Tunes (aka DJ Crappy Turntable) has been reborn as the beautiful and talented “The Little Princess!” To see/hear some of the genesis of this beautiful machine, please see our previous post. Below is the first video of The Little Princess. Here, Kane is taking her for a ride…
