However, [Jeremy P Bentham] has found a way to leverage the Pi’s hardware to overcome these limitations. The trick is using the Raspberry Pi’s little-documented Secondary Memory Interface.

And how much prettier can you get than an LED matrix? If you're interested in sprucing up your room or office with a cool light show, this Raspberry Pi project may be just what you're looking for.

With Opto-pi, there is not an electrical connection between the Raspberry Pi and connected loads (motors, relay coils, etc.) or input signals. Opto-pi uses light to isolate the 8 digital GPIO pins.

Which is amazing. Too much interface: the ports on the Raspberry Pi This led me to thinking of an analagous digital parallel: the miniaturizationism of the interface in software.

Inspired by the Google Creative Lab’s anypixel.js project, London-based Solid State Group has created a huge LED wall which is powered by a Raspberry Pi and takes pride of place in their office ...
