Here is a great weekend project for your office.
As in any office, my co-workers and I experience several WTF-Situations during our working day. So we decided to implement a simple system to count the WTF’s and use them as a metric for our working climate :-)
The project is built using arduino that send the string ‘WTF’ on the serial line, using a python script writes them to a file and a Processing app that counts the lines in the file and offers the result via http. This is further read by another processing app for visualization.
To find out more info and download processing code, see the blog.
