  • Weekend project: ShairPort menulet

    Update: New version built around a native Cocoa port of ShairPort, MacShairport: ShairPort-v0.2.1.zip) Recently an open source emulator for AirPort Express / AirTunes was released by James Laird. I’ve been waiting for something like this for a long while to enable remote music playback on my media center from my laptop and iPhone. However, I lack the […]

  • Hello Fun-A-Day 7!

    For this year’s Philadelphia Fun-A-Day project I decided to write “Hello World” programs. “Hello World” is a traditional programming tradition where a programmer encountering a new language writes a trivial program which displays the phrase “Hello World”. This introduces the programmer to the basic syntax of the language and demonstrates that their development environment is […]

  • Compiling tesseract v3 for iPhone

    Update 2: Before using the script, ensure that you can build tesseract for your host system normally. Also, I only tested the script with the v3 release of tesseract, not svn HEAD. If you get build errors, please try with rev 498. Update: The script has been updated, thanks mostly to the prompting of fopen2003 […]

  • LEITv: Fly or Pie show

    This assignment was to develop a concept around a two-screen, live event experience; specifically, using TV and computer via internet. Our group’s concept was a variety-style, Gong Show inspired show with binary voting from viewers to determine via aggregate whether a performance was Fly (a rousing success) or Pie (a miserable failure) which received a […]

  • Parsing foursquare KML files

    We’re using Foursquare as a data logger for one of our assignments in the Telling Stories with Sensors, Data and Humans class at ITP. As an aid to begin understanding the relationships between venues for our tracks, it’s helpful to munge the KML into CSV so it can be plotted and played with in a spreadsheet, […]

  • Sinatra + Kara == qwerty animals

    Yesterday I released a small web app; it was my first using the Sinatra microframework for Ruby: http://qwerty.robertcarlsen.net The app arranges illustrations of animals wearing lettered t-shirts to create user-supplied messages. Kara Schlindwein created the illustrations as part of her project for the 6th Annual Fun-a-Day project in Philadelphia, and I wrote the first draft of […]

  • OCR for iPhone source

    The source code for the Tesseract OCR for iPhone project has been published. It’s really simple – more of a skeleton, proof-of-concept project than anything else. Still, though, it’s neat to have nearly point-and-shoot text conversion in your pocket. The project page is: Pocket OCR The source code is available at github: http://github.com/rcarlsen/Pocket-OCR There is […]

  • OCR on iPhone demo

    Update: Source code for demo project released. i finally got around to building a proof of concept implementation of tesseract-ocr for the iPhone. months ago, i documented the steps which helped to get the library cross-compiled for the iPhone’s ARM processor, and how to build a fat library for use with the simulator as well. […]

  • PinwheelBeta – adhoc

    In preparation of submitting Pinwheel to the App Store I’ve gone and released a beta version via ad hoc distribution. Seems like it should be a straightforward prospect, however the various device provisioning, code signing profiles and entitlements made it a bit of a process for a first-timer. iTunes also seems to be entirely unhelpful […]

  • openFrameworks iPhone 3GS / OS 3.0

    i’ve been dealing with a performance bug in a particle + accelerometer oF app. the same project which has run very smoothly on a first generation iPhone with OS 2.2.1 has a noticeable stutter on an iPhone 3GS with OS 3.0. there was no improvement despite several rounds of optimizing the openGL drawing code and […]
