DLP-RFID1 for Processing

I recently had to set up a Processing application to monitor 15 RFID readers. The source was in C++ so I made a quick port to Processing. I'm adding it here in case it's of use to anyone using a DLP-RFID1 device. Is there a better way of doing it? ...

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 ...

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 ...

Arduino Leonardo and Windows 8

Ran into a problem installing the Arduino Leonardo on Windows 8 yesterday and I thought it would be useful to other people (including me, when my memory fails) to document the solution. Although the Leonardo does not require FTDI drivers, it still requires the COM port drivers to be installed. Windows ...
