Sixty Symbols

The University of Nottingham have produced an excellent collection of videos covering a huge variety of Physics topics, such as "Do electrons stop moving at absolute zero?" and "What happens when two black holes collide?"
I have watched several of them now and can highly recommend the lot!
Go to http://www.sixtysymbols.com/ for full details and the videos.

Sixty Symbols: Periodic Table of Videos

"Tables charting the chemical elements have been around since the 19th century - but this modern version has a short video about each one. 
We've done all 118 - but our job's not finished. Now we're updating all the videos with new stories, better samples and bigger experiments.
Plus we're making films about other areas of chemistry, latest news and occasional adventures away from the lab.
We've also started a new series - The Molecular Videos - featuring our favourite molecules and compounds.
All these videos are created by video journalist Brady Haran, featuring real working chemists from the University of Nottingham."

Raspberry Pi and Breadboard (Raspberry Leaf)

If you have ever tried connecting jumper wires to a Raspberry Pi then you will have noticed that unlike other systems, the pin names are not printed on the PCB.
While not a showstopper it is a bit of an irritation, especially as my two older Pis have different pinouts to current ones, which is why I was so interested by this idea from Dr. Monk's DIY Electronics Blog
They are simply printed paper templates that push over the GPIO pins making it so much easier to see what you are doing, and I can tell you after this weekend that they really help.
You can grab copies of these templates from http://www.doctormonk.com/2013/02/raspberry-pi-and-breadboard-raspberry.html
