Anonymous

Anonymous browsing is all the rage nowadays, what with government snooping on the increase. Well now you can set up your Raspberry Pi as an anonymous router which shows up as a wireless hotspot which you then connect your desktop or laptop computer to over wifi. Take a look at this tutorial for how to do it. This tutorial is also useful for if you want to create a wifi hotspot for robotics.

Projects

DesignSpark have published some good-looking resources for teachers to use in the classroom to help students learn about the GPIO. They are as follows:

• Program a seven-segment display.
• Read digital signals and analogue signals (via an A2D chip) and how to generate an analogue output.
• Read a one-wire temperature sensor and then output the reading to a multiple-digit LED display.
• Controlling a motor using a L293D driver chip.

They look good-quality documents with plenty of Fritzing circuit diagrams to help you. Each resource comes with worksheets for students and classroom notes for teachers.
