Sunday, May 29th, 2011

Rafael and I found this 7 segment LED display tonight while tinkering a bit. We didn’t knew what it is at first but after searching around the web we found out that it was a very vintage 7 segment LED display with 3 digits… ;) It is a HP 5082-7433.

Arduino Motion Sensor Server

Wednesday, May 25th, 2011

I tinkered a little bit this evening and I have added a motion sensor to the Arduino platform. After that I added a network shield and have coded a small HTTP server… This server provides just a 0 or an 1. 0 if I don’t have moved around; 1 if I am dancing on the desk… ;) The sensor works with a radius of about 5 to 7 meters and it is really a lot of fun. You could get such sensors very cheap at ebay, just search for “arduino motion sensor”.

I am getting the status every second using wget and are displaying the output in xterm. It looks nice to see how much I am moving when writing this Blog post:

I was on holiday in Denmark last week. It was a great time. Since I was on a danish school, I were there many times in my youth. I felt very well @home… ;)
