This post describes how to use I2C peripherals with the Clixx.IO system. Although it focuses on using the Raspberry Pi as a host most of the concepts apply to other microcontrollers as well. It will describe how to set up I2C functionality on the Raspberry Pi, build a Clixx…

The PiStation

Ever since I got a Raspberry Pi I wanted a small standalone case to put it in. There are any number of cases available already (simply search Thingiverse for a nice range of options) but each of them simply provided a case to protect the circuit board, what I was…

PiStation Redesign

Over the past few days I've done a bit of work redesigning the frame for the PiStation. Everything now fits together very nicely with plenty of space for circuit boards and cabling while still leaving access to the Raspberry Pi GPIO pins. This post is a run down of the…

PiStation Updates

Despite a very hectic weekend where I didn't get a lot of time to spend on the project I've managed to make some progress on the PiStation. First up was testing the button circuit and making sure I could read the button state from the GPIO (oh, and making sure…

Introducing the PiStation

I'd like to introduce you to the PiStation, this is my weekend project which turned out to take a bit longer to finish than I had anticipated (isn't that always the way?). On the plus side I at least have a working prototype and only a few rough edges to…

The Raspberry Pi

The Raspberry Pi is a small (around the size of a credit card), cheap (about $US 35) and versatile (it runs Linux and a wide range of free open source software) computer. Although it is not the first of this type of device it has certainly captured the attention of…

Adding Some Smarts to Projects

Being able to add a level of smartness to projects can greatly extend their usefulness (and make them more interesting). The smartness usually involves some level of electronics - today the number of options available to do that is much greater than it ever was before, and more importantly, well…
