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 new design. The first thing I needed to do was move the the button row to the bottom of the front panel to allow space for the PCB the buttons are mounted on. You can see how it all fits together in the image on the right (all held together with sticky tape for the moment). I added mounting stubs for the button PCB so it can be…

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 I didn't let the smoke out of the Pi with the circuit either). I put the circuit together using a set of breadboard cables I got from Adafruit. Not as neat as I normally like but certainly quick and easy to do. To test it I wrote a simple Python program using the RPi.GPIO library. All it does is periodically poll the status of the IO pin…

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 sort out. Basically this is a simple case for a Raspberry Pi that includes some buttons for input and an LCD screen for audio and video output. It leaves the Pi accessable so you can use it as a nice portable base station for hardware hacking. Have a look at the project page for more information. There you'll find links to the GitHub reposito…

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 a lot of people in a very short amount of time. This post tries to explain the Raspberry Pi in the bigger picture - what it's for, what the intentions behind the project were and how it has the possibility of ushering in a sea change for education. What is the Raspberry Pi for? To clear up any misconceptions the Pi is not immediatel…

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 within the average hobbyists budget. To explore what can become possible with various levels of complexity I'm going to use the example of a display table. The general idea is a coffee table with a recessed rectanglar area covered by glass or plastic that is used to display small objects - a fossil col…
