Three20 TTTableViewController commitEditingStyle

This post is mostly for my future reference. I found the documentation of the TTTableViewController's commitEditingStyle to be lacking. Some of the comments on StackOverflow provide the right answer, but the code wasn't posted so I struggled for a bit. Below is an example of the version I managed to ...

Augmented Reality

Recently Saqoosha's port of ARToolkit from C to Flash has taken the Flash world by storm. The biggest hurdle for me was that the comments in the source were all in Japanese. That was until Mikko Haapoja published a getting started in FLARToolkit entry. Now we're witnessing an onslaught of ...

Thinking out loud — Arduino as Webcam

Lately much of my work has been dealing with getting Flash to talk to the Arduino. There's no real functionality to do this on its own, so you have to rely on some other components to host the conversation. There's a whole host of methods you can use here: Socket Connection ...

Mapping GPS Data

When I last left the data logger project off I was having quite a few issues with managing the size of the data in the allotted EEPROM space on board the Arduino. I built up an SDCard writer based on several specs I found in the messageboard and it worked ...

Conversation Clouds with Physics

So after posting the previous entry I went to sleep, only to find myself thinking about improving the visual aspect of the Conversation Cloud. I decided that adding physics would be the way to go, it would allow words to deflect off of each other, grow and gain mass, and ...

Conversation Clouds

Word of mouth is one of those impossible things people like to track. The best people seem to be able to do is to ask the question on a registration form, "Where did you hear about us?" Is it possible to track word of mouth any better? This is the premise ...

The Great Internet Migratory Box of Electronics Junk (TGIMBOEJ) is a box. It's a box that arrives on your doorstep after you drop your name on a wiki page and wait a good deal of time. It's a box that has electronics junk inside and it works off the premise ...

Power Monitor Packet

As Hugo helpfully commented in a previous post, here is the link to the Power Monitor Patent. The specific page I'm linking to is the Packet model. Lots of reading to do here, but its pretty interesting. One of the things I find most interesting about this patent is the citations ...

Building a Scooter Bike for Kids

Ages ago I bookmarked a design posted on Make for a Scooter Bike, as I intended on building one when my daughter got old enough. On a recent trip to the surplus store I picked up a wheelset for $3 and figured what better time to start than now. I ...

Without an access to an oscilloscope with packet capture capabilities we built our own with an Arduino. Essentially, the code waits for ...
