JLL Piano – Raspberry Pi Music Clip player

Monday, October 15th, 2018

This project is called the JLL piano. This is a school project that my daughter created for her music homework. She needed to create a project that related to Jerry Lee Lewis and she created a mini piano that plays a short clip for a different song depending upon the key that is pressed. It […]

Updated Linux and Raspberry Pi Tutorials

Tuesday, March 27th, 2018

One of the things about creating a web site is having to keep it up-to-date as changes happen. In the case of my PenguinTutor web site that is the changes in Linux and the Raspberry Pi over the last few years. In particular a new release of Raspbian was created last year (based on Debian […]

Today is the weekend of the Raspberry Pi 6th Birthday. In the past the birthday has been celebrated with a large Raspberry Jam in Cambridge (organized by Mike Horne and Tim Richardson).

World Book Day – Raspberry Pi and Pimoroni InkyPHat Badge

Thursday, March 1st, 2018

Today is World Book Day. For the last few years I’ve been supporting my local school by helping run their book sale. Last year I dressed up as The Wizard of Oz complete with Wearable Electronic flashing bow tie. This year I am a little more subtle as I won’t be wearing a full costume, […]

Thursday, February 15th, 2018

The ESA European Astro Pi Project – “Mission Zero”, involved school children creating code that actually ran on the International Space Station (ISS).

OMSCS Studying online – MSc in Computer Science with Georgia Tech

Wednesday, January 24th, 2018

I’ve recently completed an online Master degree with Georgia Tech. This has been a huge commitment in terms of time, but I’ve learned a lot. “University Master Degree – same as on-campus but it’s online” As an online course the cost is only a fraction of on-campus classes, and in my case my employer covered […]

The power of open source – Creating a GUI with Python and guizero

Saturday, January 13th, 2018

This isn’t going to be a guide about how to program a GUI (graphical user interfaces) using guizero (hopefully I’ll add some instruction on that in future), but it does explain which I chose guizero, some of the concepts I used and a bit of an insight into this open source software library. Adding GUIs […]

Upgraded Networking Challenge for Computing fair

Friday, January 12th, 2018

I have written previously about a school computing fair that I helped support. I went along again this year as a way to promote STEM and in particular computing. As I work for a telecommunications company then I wanted to promote computer networking as a career option. I didn’t want to just talk about computer […]

I backed the MeArm Pi kickstarter project earlier this year, and just received the finished product. It’s a, laser cut, plastic robot arm which has a built-in Raspberry Pi. It is created by Mime Industries who have previously created a similar robot arm without the build-in controller / Raspberry Pi. It can be controlled using […]
