Connection Cloud

Every once in a while I think of a project and just have to pull something together to satisfy my own inner-geekiness. This was one of those projects.

In my humble opinion, few images are as personal and as striking as the visualization of an individual’s social network.

Since then, developers have been taking advantage of these newfound sources of information in order to provide Facebook users with fun and interesting “applications” for their personal profiles.

On GPS Accuracy with the Tripmate

I am a huge fan of my Delorme Tripmate. It’s a cheap serial GPS receiver that it is very easy to work with and interface with my microcontroller projects. It was introduced over 10 years ago and mine is still in great condition. I’ve used it for a number of projects (e.g., PIC16F88 Delorme Tripmate GPS Logger, GPS Logger with Time and Speed, and a modified version for GPRMC) and I plan on creating more. However, it’s starting to show its age and I have found that over time I’ve become less and less fond of its chipset. The biggest problem has been the gross inaccuracies in reported position.
