Here are some of the more recent offerings that make it easier to build cool gadgets of your own.
Just funded on Kickstarter, Flotilla is aimed at making hardware hacking accessible to everyone.
Flotilla provides a dock that allows you to easily connect your Pi to sensors that detect motion, light, colour, pressure, touch and more, as well motors and simple screens. Controlling these electronics and linking them together can be done by dragging and dropping commands using a simple graphical interface.
Price: £24 ($36) - £109 ($165)
