Most people don’t understand the low-level fundamentals of computers. Computers are made from transistors… a ton of them. When you start in on your computers science degree, the first thing you learn is programming languages, algorithms, computer architecture and the beginnings of networking. These are all VERY high level abstractions of what is happening inside… Continue reading Computers… from the ground up. A mini series… (part 1)

The Sense Hat What’s a hat? Hats are the term that the Raspberry PI community uses to identify bits of hardware that are made to plug into the Raspberry Pi’s GPIOs (General Purpose IO) – that row of pins along one side of your pi.  There are lots of these out there to make interacting with… Continue reading Lessons on PI – Lesson 4: The Sense Hat (and a little VIM)
