For the forth coming [brixhibition] Exhibition at the end of April, I have been asked to set-up and run a couple of interactive Robot Soccer fields.The Robots needed to be robust and reliable as members of the public will be interacting with them. Also they need to have a a simple, intuitive, and easy to use hand held controller. I have used Sony Playstation PS-2 Controllers, but they have far too many controls that would be unused and confusing to the first time operator. I chose to use a Nintendo Wii® Nun-Chuck Controller for the job.

How to License the Universe, and then Rule Us All!

How licensing deals helped LEGO become the most profitable toymaker in the world:
  • LEGO, pre-millennium: stackable bricks, generic yellow-headed characters, revenue sputtering.
  • LEGO today: Crushing the toy industry under its interlocking feet, having overtaken Mattel and Hasbro as the most profitable toymaker in the world.

That’s partially due to licensing deals, which, starting in 1999, and added icons like Darth Vader and Batman to the mix. Many other properties followed—and The LEGO Movie, out from February, features many of our favorite modular heroes meeting for the first time.

Setting Up a Static IP Address for the Raspberry Pi

Static IP Address
en.pdf24.org    Send article as PDF   
When you wish to log in to your Raspberry Pi remotely, you will need the IP Address of the Raspberry Pi. By default, the Raspberry Pi will be given an IP automatically by the router (called Dynamic IP and denoted by DHCP) when you connect to a network. However, as the name suggest, the IP can change whenever you remove the Pi from the network or turn it off.

Having a static IP isn’t essential, however it will make repeated access to the Raspberry Pi via SSH and VNC much simpler, as you will always know that the Raspberry Pi has the same address every time.

Remotely Control the Raspberry Pi using VNC

Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network. VNC is platform-independent – a VNC viewer on one operating system may connect to a VNC server on the same or any other operating system. There are clients and servers for many GUI-based operating systems, including Java.
I will endeavour to explain how to install and use VNC with your raspberry Pi. This will allow you to see/use the Raspberry Pi’s graphical desktop remotely, using the mouse and keyboard as if you were sitting in front of your Pi.

The staff at Dexter Industries have busy developing an interface between the Raspberry Pi, and the world of Arduino called the Arduberry. The Arduberry allows the mating of Arduino shields too the Raspberry Pi with a simple, inexpensive hardware interface. Slide the Arduberry onto your Pi, fit a Arduino Shield, copy your Arduino code across, and hit the go button.
