Weekend project: ShairPort menulet

Sunday, April 17th, 2011

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 hardware skills to extract the necessary firmware from the AirPort Express ROM chip. Thanks to James for doing the work and putting out his perl script / c utility. It’s pretty simple to build and run, and the source includes a nice OS X launcher script, but I’m looking for a little GUI widget to easily control it lest someone ‘inadvertently’ decides to send audio to my computer.

I’ve been lately transitioning my iPhone-specific Cocoa knowledge to the desktop; this was a nice opportunity to wrap up the ShairPort scripts in an OS X menu bar widget. The source is available on Github, and you can get the bundled app below. This was made for my specific system, so YMMV.

Mobile Logger – GPX extensions

Tuesday, August 10th, 2010

gpx-extRolling the extra logged sensor data into the GPX export took more effort that it should have…but I uncovered and fixed a latent bug in the export feature, so that’s a win right? Regardless, it’s was nice to use the new issue tracker at bugs.robertcarlsen.net for real(z) for the first time. I’m looking to get several other features implemented before the next released update…planning on a few weeks. Otherwise, code is available, as always, on github.

Mobile Logger GPX + GoogleEarth

GPX export seems to be working, and imports fine into Google Earth. This is just a basic implementation of the essentials for a route; I’d really like to include other recorded sensors somehow into the track – maybe it could be a layer in Google Earth?

Looking at the ride data here reveals just how bad raw GPS data can be between tall buildings in NYC. Several data points often share the same GPS location. It seems that moving quickly with a clear path to the sky gives the best performance.

The app also quit midway though the ride – I have to look into that.

GPX export is available in the github repository.

Basic GPX export has been added to the github repo. That is all.

OCR for iPhone source

Tuesday, January 12th, 2010

ocr_gobbledygookThe 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 certainly a lot of improvement to be made. Automatic color correction. Page layout recognition. Perspective correction…the list could go on. The code is there, so…fork away!

(the thumbnail is a bit tongue-in-cheek…but honest. good conversion requires a good source image: well-lit, macro, focused and tightly cropped seems best)
