Sam Blanchard, an Assistant Professor of Sculpture at Virginia Tech, has developed SeeMore. SeeMore features 256 Raspberry Pis attached to servo arms. It works as an enormous parallel-processing computer but it is also articulated to show how it works as a cluster. There is a touch screen attached which allows visitors to set the cluster tasks to perform. The Raspberry Pi Foundation covered it on their blog and you can visit Sam’s website here.
Jeremy Morgan has recently been tinkering with a bunch of sensors attached to a Raspberry Pi, out of which he has made a ‘weather station‘. The station measures temperature (several different ways!), humidity, barometric (atmospheric) pressure and light levels/luminosity (lux). He has now written up the whole thing as a tutorial on his blog. Read it here. It’s a really good way of getting into sensors and showing them on a web interface, so great job Jeremy! For those of us in the UK, all the parts specified in his tutorial can be purchased from either The Pi Hut or Makersify, as well as other sources such as Element 14.
Back in November 2013, Bonnie Eisenman and her team used light sensors and torches to create a set of musical stairs at Princeton:
The team have now written up the project as an Instructable so you can create your very own set of stairs! Take a look here.
