Convolution Explorer

Here’s a quick-and-dirty little tool which allows you to explore the effects of various convolution kernels on an image.

GeoGebra

I always keep an eye out for software that makes diagramming easier, and the other day I came across GeoGebra. GeoGebra is a fantastic, free (as in freedom), Java-based mathematical illustration tool that includes support for plotting functions.

Similar to Mathematica Player, diagrams are fully interactive and can be exported as embeddable Java applets.

Perhaps best of all, no installation is required. GeoGebra launches through WebStart.

Here are few examples that I whipped up:

My good friend, Chris Arges, set up a song exchanging site, noise.chrisarges.net.  The intent of the site is a place to post WIPs or beta tracks for your friends to critique and mash-up.

I, myself, ain’t much of a musician, but I love playing with Ableton Live and Reason, so I composed a few tracks to help get the site going. Here’s one of them.

(Headphones or a decent pair of speakers, strongly recommended)

And this is why the Internets are simply, awesome.

Here are a few sketches I created while working on my next article. The videos are mostly droplet simulations, rendered using the Cinema 4D Sketch & Toon module. The background is from bittbox, and the damn catchy tunes are from the Ting Tings, Les Hommes, and the Papa Fritas, respectively. The trailing video is a test of the C4D formula modifier. All the videos were composited in After Effects.

Vibrotactile Stimulus Verifier Shield

I’m a Graduate Research Assistant at the Haptic Research Interface Laboratory (HIRL) at Purdue University. Being a Haptics Lab, we primarily study the sense of touch; investigating the modes of tactile sensation and exploring ways to deliver information to humans by means of it.

Freescale MC(Z)33970 Dual Gauge driver IC

 While designing an ambient display project, I came across the Freescale MC(Z)33970 Dual Gauge driver IC.  The part seemed interesting, so I ordered a sample and whipped up a small C library to use in conjunction with a perf-boarded USB Bit Whacker I had on my workbench.  (An Arduino library is also available below)

Breadboarded USB Bit Whacker

Every so often you come across a reinvention of an old idea that blows you away, not only in its elegance but its sheer utility.  For me, this occurred a few weeks ago, when I came across the USB Bit Whacker.  The name was familiar, I’d surely seen it while browsing the Sparkfun product catalog, but for some reason the description hadn’t compelled me to click.

To help keep my series of articles on microcontroller development on Mac OS X concise, I’ve decided to spin-off somewhat tangential topics into their own posts.  Here’s mini-post on powering the Technological Arts NanoCore C32 development kit.

DIY right-angle header up-close

 I often find the need to stick headers on my microcontroller projects, and I’ve come to prefer right-angle headers, as opposed to the traditional straight header, due to their unobtrusive, low-profile. Since right-angle headers are usually in low-supply, here’s a couple of ways to make or acquire them from parts you probably have lying around. (The peripheral in the pictures is the LIS3LV02DQ 3-axis accelerometer)

GPS Logger Prototype

A few years ago, I came across a fantastic deal on surplus GPS modules on eBay. Given the high tinkering potential, and unable to pass up a deal, I picked up a few. Predictably, work started piling up, and the modules were relegated to collect dust in my parts bin. Earlier this month, my cousin and I decided to make a surprise trip down to Houston; what better time to slap together a project and test out the modules than a cross-country trip?

I intend for this to be a series of posts explaining how to get up and running developing for the Freescale HC(S)12, Atmel AVR, Microchip PIC, and ARM LPx platforms. These instructions have been tested on my laptop, which runs Mac OS X Leopard. However, there is nothing *explicitly* Mac-specific about what I’ll be covering; most of this guide should apply to *NIX platforms, and possibly Windows, too.
