Every day, every moment, is an opportunity to learn

Building a Morse Code Transmitter on a Raspberry Pi

Last week, I made the Raspberry Pi blink an LED a few times. As thrilling as that was ;) I almost immediately wanted something more. That led me to… Note: Source code for this project is available on GitHub. Goals Setup a simple circuit (LED and resistor) using a breadboard Learn about Morse Code in order to correctly translate a sentence Manipulate the...

“Hello World” for the Raspberry Pi (Making an LED Blink)

I finally unboxed my Pi a few weeks ago, and since then I’ve been learning some Python, which is the primary language of the Pi. You can do fun things with it out-of-the-box, like running and modifying the Python games that install with Raspbian (as well as writing your own), or playing around with MIT’s Scratch program (which also comes preinstalled). Or you could try another OS,...

A Tail of Recursion in Erlang (a C# developer’s observations)

A group of us at VHT has been meeting weekly, reviewing some Erlang basics and running through examples. Even though it means giving up a lunch hour, over a dozen people have still been showing up to learn and help each other. Two of us were recently challenged to figure out a couple problems in Erlang without using obvious built-in functions: Determine the length of a list. (without...

Learning Python for the Raspberry Pi

Once you’ve connected the peripherals, installed NOOBS, and gotten your Raspberry Pi up and running, pat yourself on the back and take a moment to bask in the glow of the large raspberry on your Raspbian desktop. Whee. Okay, that’s enough gloating, ya narcissist. So now what? Choosing a Language After getting my first Raspberry Pi 2 up and running last weekend, and taking some cursory glances...

Getting Started with the Raspberry Pi 2

I got a Raspberry Pi 2 for Christmas, and finally took it for a spin this weekend… just as the community is getting ready to celebrate the Pi’s 4th birthday. After using it for a few hours, here’s what I’ve learned so far. Invest in a Starter Kit The base Raspberry Pi 2 board is only about $35, but it comes with nothing else, not even an ac adapter....

Must… resist the temptation…. oh, for pete’s sake just MOVE OVER and let me do it!

One of the coolest things about being a parent is getting to teach your kids something new. A new game, a new skill, something they didn’t “get” before. It’s a bit of immortality, in a way. Imparting something onto the next generation! Okay, so it’s not always grand. Sometimes we’re just trying to unload something we always have to do, like getting their own milk or clearing the...

How (and why) I built my kids a bunk bed instead of buying one

Last summer, my wife was looking to reorganize the homeschool area of our living room. We had a few smallish book cases lining the wall, all different colors and sizes. They were beat up, shelves sagging. It was time to replace them, and she wanted something big enough to hold the dozens of text books, papers and other materials that homeschooling requires. We...
