Convert a Folder of .WAV files to numbered .MP3 files
A quick bit of bash that you can do from the command line on linux (or MacOS, if you have lame installed)…

Daisy Chaining AD5204 Digital Potentiometers
I’m using an Arduino to control two (maybe more – I haven’t tried yet) AD5204 digital potentiometers. Here’s some info about adapting the digital pot Arduino example to work with daisy chaining.

rdqcutils Quartz Composer plugin
During my weekend of procrastination, I created a Quartz Composer plugin. As I need some new patch I will probably add it to this plugin, so it will continue to grow. Continue reading “rdqcutils Quartz Composer plugin”
Mapping a value to a new range
A handy formula that I usually have to look for when I need it – make a value fall into a specific min-max range. This is the math that gives you a new, scaled up or down, value.
20 Challenges
This is a list of twenty arbitrary challenges for people who are learning to create using a tool like Processing, Quartz Composer, or the like.
Using OSCemote with Processing
This is my tutorial for using Processing with the OSCemote iPhone app.
escbox
I made a big red button to replace the Escape key. A museum that I’m consulting for needs this for a touch-screen kiosk that runs Crayon Physics.
iPhone and Processing
I made a couple simple demos for the VIS145A students at UCSD to show how we can use an iPhone as the interface to Processing sketches.
Creating Visual Rhythm in Processing
I’m teaching Processing to art students at UCSD and the course’s professor has basically asked them to create visual rhythm. I made a few sketches to show a simple way in which this might be accomplished.
