Countdown to Christmas with the Arduino advent calendar!

This year, as part of the publicity for their Christmas charity gifts, Concern Worldwide (who I’m lucky enough to work for) commissioned an artist to come up with a design for an advent calendar. The resulting design by Robert Fiszer is really rather lovely (you can check out the campaign here)- and lends itself rather well […]

Official Raspberry Pi touch display review

This week saw the launch of the official Raspberry Pi display, so I thought I would write up a quick review to share some of my initial thoughts about the device. Ever since the first version of the Pi there’s been a DSI connector on the board – and although there have been lots of […]

Ryanteck Raspberry Pi Serial Debug Clip review

The Ryanteck Raspberry Pi Motor Controller Board Kit is a GPIO add on board that allows you to control 2 motors with […]

Raspberry Pi LED scrolling sign

I’ve been playing around with LED scrolling signs for a while now and have been looking for an affordable sign to use for a project. Some LED signs are really expensive but I’ve recently come across this one from Embedded Adventures: It’s a 80×8 display with three colours – Red Green, and Red/Green mixed to […]

Kano the Raspberry Pi go mainstream?

Since its launch the Raspberry Pi has been phenomenally  successful – with over 2 million units of the little computer sold around the world, it’s arguably kick-started a revolution in cheap, educational computing. The only slight worry about this is how many Raspberry Pi computers have landed in the hands of kids (who it was […]
