(binary) C10CK app in App Store!

Thursday, May 12th, 2011

My second (personal) iPhone app, C10CK, is now available in the App Store. It is a clock which displays time using binary notation – the same way everything is (eventually) stored in a digital computer. I’ve been using a binary clock since a staff member of ITP passed this past year and several alumni recalled stories of the binary clock she kept on her desk and would happily explain to anyone who asked. I now keep a binary clock on my desk and think of her when people ask me what it is. (more…)

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.

Sinatra + Kara == qwerty animals

Saturday, February 20th, 2010

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 the app while sitting in a chair at the show a couple of weeks ago, still nursing my broken ankle.

OCR on iPhone demo

Sunday, December 6th, 2009

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. several folks have helped immensely in noting how to actually run the engine in obj-c++. thanks to everyone who has commented so far.

anyway, below is a short video of the POC in action. the basic workflow is: select image from photo library or camera, crop tightly on the box of text you’d like to convert, wait while it processes, select / copy or email text. (more…)

Summer time: BeachBall

Thursday, July 30th, 2009

beachball_submitThe BeachBall app has been submitted to the iPhone App Store. I’m pretty sure that I’ve crossed all the t’s and dotted the i’s throughout the application and am holding out hope for a smooth process. If all goes well it will be a great surprise just before the next semester kicks off.

Thanks to everyone who has been beta testing the (codename) Pinwheel app. I’ll be sure to give you all a copy of the final app when (if?) it’s approved.

In the meantime there are several other projects which need my attention. I’m committed to getting the in-progress work finished before moving on to new stuff…which is a strong motivator since I have a few things I’m really excited about working on. Onward…!
