Teach Me To Make | Resources for Makers. EAGLE Tutorial: Ground Planes with Polygons. DIY iPod Passive Preamplifier. The impedance mismatch that makes your tunes sound mushy. A lack of output voltage means that you have to crank up your stereo volume to get a decent listening level. (And the corresponding heart-attack when you switch your amp from iPod to radio or CD and the volume is through the roof.) There's this Fellow Named PRR Being the well-adjusted successful guy that I am, I like to spend endless hours cruising the internet reading forums, articles and just about anything related to audio electronics.
While digging through iPod to Line-In mismatches, I happened across this wonderful thread. A fellow name PRR posted a few solutions, one of which was a passive, transformer-based circuit that purported to boost low-voltage output devices such as an iPod. I was transfixed; here was a passive (no external power required!) Using my small test rig for transformer hookup The end result? So Let's Build One! This device is really simply, basically four parts. Here's the schematic: All wired up. Sharing Music’s Source Code: Event Pairs Performances with Code, Patches, Schematics. Augmented cyborg performance by Onxy Ashanti, built with free tools and with freely-shared hardware, in the hopes of accelerating the rest of the musical human race. Photo courtesy the artist. At the Metropolitan Opera in New York, high in the rafters, there’s a set of unusually-cheap seats called the Score Desk section.
There, in addition to the seating, panels of wood are oversized enough to accommodate full-orchestral scores. While leaning over the railing to see the performance (the section is not for those with fear of heights), studying composers, conductors, and musicians can pour over the details of Debussy’s orchestrations or Verdi’s prosody. Now, the line between tool, instrument, and composition is blurred, whether we’re talking dance music or experimental sounds. So, in a new event we’re kicking off in Berlin this Saturday night, participating artist are sharing the guts inside their performances. But the experience could be a return to the tradition of the score desk. LushOne base module kit : Lushprojects.com Store, A feast of electronic fun. Have you always wanted a modular synthesizer but never been willing to pay the price? With the LushOne kit you can experience the strange, fun world of modular synthesizers without breaking the bank.
The idea for the LushOne occurred when I was thinking about buying a modular synth but couldn't bring myself to pay what they cost. I thought "wouldn't it be good if someone would make an equivalent a Sinclair computer for the modular synth world? ". I tried to design a modular synth that stripped out all the costs while providing an instrument that is cheap and flexible to allow people to get started without a big commitment. The LushOne is the implementation of this vision. The LushOne kit is designed to provide the core functions of a modular synthesizer in a low-cost single board design. The built-in modules of the LushOne create classic sounds that are reminiscant of much-loved early synthesizers.

This tutorial was featured on the CadSoft website on 06/19/2012 In the course of making my Arduino Tutorial Series (don’t worry, I have more of those in the works), I got a ton of requests for a tutorial series on how to design circuit boards. Now, I’m answering those requests with my Eagle Tutorial Series! Supported by element14 & cadsoft, this series will take you through the process of designing a complete PCB using the very popular Eagle CAD software. In this first tutorial on CadSoft Eagle, I’ll show you how to get the program up and running, how to navigate the interface, how to design your first schematic, and how to use DesignConnect to build a Bill-of-Materials. This tutorial has been made possible with support from CadSoft and element14.

The MidiVox CV sketch has been updated to work with Arduino 1.0 - grab it here Also be sure to use the new version of the Midi Library as well! Also, also: Some previous comments on earlier posts seem to have been lost in a recent Disqus migration - apologies to previous commenters. Perhaps you noticed narbotic.com looks different? It is different! A big thanks to everyone who picked up a MidiVox kit - you are now the proud owner of a rare piece of electronics.Though the kit is no longer in production, there is now a new version of the Midi Libray which has been updated to work with the Arduino 1.0 IDE.
In addition to an aesthetic reboot, this site will now serve as your premiere destination for all things Collin Cunningham on the web. New things are in the works - more to come The industrious & talented Mr. (Big thanks to Peter for sharing his code & cluing me in on this a while back via twitter) To put that in a more “step-by-step” context: Healer v2 can be downloaded here. A-100 do it yourself page. This document is intended for A-100 users who want to learn a little bit about the technical details of the A-100.
We will start with some electronic basics and introduce at first the most important electronic parts used in the A-100 circuits. Then we will show how some basic circuits (like attenuators, amplifiers, mixers, inverters and so on) can be realized with these parts. The following paragraph will show some simple modifications of A-100 modules: e.g. changing the sensitivity of CV or audio inputs, increasing or decreasing output levels (e.g. VCAs or mixers with maximum amplification > 1), adding offset feature to mixers, changing between DC and AC coupled inputs/outputs, adding feedback inserts for VC resonance to all filters and many more. This page starts September 2004. Additional information about technical details (e.g. The A-100 service manual is available only for A-100 customers (see price list for current price).

This circuit probably looks all wrong – we’ve got an NPN transistor with its base connected to ground, the emitter connected to the positive supply railvia a resistor and the collector hanging out in the breeze! If we’re trying to build an amplifier, yep, this circuit has real problems. But if we’re building a very simple white noise generator, then this circuit is perfect. It doesn’t seem to be all that well known that transistors when reverse biased actually produce decent amounts of white noise.
White noise is random noise across the entire audio spectrum. This particular circuit generates a good couple of volts peak-to-peak of the stuff and can easily be coupled to an audio output amp if you wanted to drive everyone nuts. The reason it works is that the base-emitter junction works a bit like a zener diode. So what would you do with a white noise generator?
