I write when I've got something to share - a personal project, a solution to a difficult problem, or just an idea. We learn by doing and sharing. We've all got something to contribute.

Create a Raspberry Pi Virtual Machine (VM) in VirtualBox

I was flipping through The MagPi back-issues and came across an article about setting up a virtual Raspberry Pi environment. It got me thinking... I’ve been playing around a lot on the Pi itself, but it’d be nice to experiment with code even when I don’t have access to a physical Pi.

Building a Morse Code Transmitter on a Raspberry Pi (version 2)

I created a morse code generator before based on entering a string at the console. Now I extended it to generate a message by clicking a button.

Using PullUp and PullDown Resistors on the Raspberry Pi

Using PullUp and PullDown Resistors on the Raspberry Pi

When you start out creating circuits with the Raspberry Pi and its GPIO pins, there's an unexpected but important concept to understand, called "floating". To adjust for it, you need to understand how to use pullup and pulldown resistors.

Building the model 4-stroke combustion engine from Smithsonian

Last summer, I found this “Smithsonian Motor-Works” set at a garage sale. Once built, it models a 4-stroke internal combustion engine. I’d shelved it for a rainy day and rediscovered it last weekend while cleaning the basement. The girls were out - time for a little father/son bonding!
