Installing Pibrella on Raspberry Pi 3 and GPIO Pins

With me traveling to Redwood City next week to visit HQ and then Oracle Open World the week after, I’m busy during many of my off hours preparing a new Raspberry Pi STEAM setup for a maker’s faire the beginning of October. I’d heard that many were having challenges with installing different HATs on their […]

Adding GPIO Pins to the Raspberry Pi Zero

Although the Raspberry Pi 3 is now available, many people are still interested in it’s cheaper, smaller version, the Raspberry Pi Zero.  This version isn’t just smaller, it also requires a Wi-Fi dongle for internet access, (one of the new, great features on the 3 Model!) and one of my main reasons for not recommending […]

Raspberry Pi Version 2 Wifi Inconsistent Connectivity

I’d had some difficulty with WiFi consistently staying connected on each of my Raspberry Pi units.  I’d had a little time to look into it, but no research had offered an answer and the only fixes I’d come up with was a shell script I wrote to force a restart of the NIC, which helped some, […]

Updating the Raspberry Pi Vbox Image

So one of the things I like to do is test out a lot of my python gaming code, (as far as for the coding and syntax) on my Oracle Virtualbox image of my Raspberry Pi.  Another great thing about building games on the Raspberry Pi, is a built in module called Pygame.  Well, that […]

Enhancing A Moving Art Project to Beginning Robotics with Raspberry Pi

Back on August 7th, the RMOUG’s Quarterly Education Workshop, I walked everyone through using a Pibrella board to create an art or flyer project that was powered with a python script and a motor. Today, we’re going to take that same code and reuse it with a simple robotics kit to control power and rotation […]

The Evolution of a Programmer and the Pythonic Way of Thinking

There’s an old joke about the evolution of a programmer. It starts with the programmer in their infancy and typing: Print “Hello World” and so the output returns: The programmer continues to evolve. His coding knowledge increases and his code in the end of his evolution becomes a script of 5000 to 10,000 lines. What […]
