Woot Arduino Printer

I recently bought the Ardunio inventors kit from Sparkfun to play around with the Arduino and I’ve been looking for a project to make with it when I saw DangerousPrototypes Thermal Twitter Printer based on their web platform. I thought that I could build upon that and use the Arduino and add and LCD to it.
Enter the finished product

It uses the Arduino, Arduino Ethernet Sheild, a serial enabled LCD, and thermal printer from Sparkfun. It works by scraping a couple of twitter rss feeds and outputting the results. The LCD parses the @wootoff twitter account and formats the results to start with the price. It checks for updates about every minute. In my next version I’d like to add a last call notification to the display.

The printer works in a simpler function and pulls tweets from the @wootchatter account that are also displayed on Woot’s community forum. I use several variables to save the last printed tweet and check it each time that the rss feed is parsed to make sure that it is not printing the same tweet every minute. In the next version I’d like to make some better formatting of the tweets to make them more readable and stand out more.
