Twitter Popularity Meter – Code

Posted by chemicaloliver on 06/10/2009

Recently I’ve been working on a popularity meter which searches twitter and displays a bar graph of the popularity of the search term on an LED Matrix driven by an Arduino. It currently relies on a PHP script on my webserver to do the actual twitter search and the arduino reads the page via ethernet and then displays the number on it bar graph.

Fritzing! (A new electronics CAD Program)

Posted by chemicaloliver on 20/05/2009

While I’ve been experimenting with circuits and ardunio stuff recently I’ve been looking for a simple solution for converting a schematic to a breadboard/stripboard design, I’ve explored a few options like stripboard magic and eagle and non seem to be ideal however today I came across a new project via twitter.

Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to take the step from physical prototyping to actual product”

Available here

It allows the user to create circuits in a simple drag and drop environment on a 3D breadboard complete with arduino template, it can then convert this design into a schematic or etchable pcb and vice versa. It is still very much in development but from my initial playing looks like a very promising project.
