G-Scale building for garden model railway – part 3 – Adding a roof and other features

Monday, December 24th, 2018

In this final part of the design for a 3D printed model railway building I’ve added additional features such as the door, windows and roof as well as adding a smoke generator. These were all designed in TinkerCAD. These are designed in TinkerCAD and then exported for 3D printing. The smoke generator is fitted into […]

3D printed Aquarium – Gift idea for Megaquarium Computer Game

Tuesday, December 18th, 2018

Megaquarium is a computer game where you get a design your own aquarium tourist attraction. It’s like Roller Coaster Tycoon, based around a Sea Life Centre. My son wants it as a Christmas present, which is great except in the days of digital downloads a bunch of binary digits doesn’t quite feel the same as […]

Raspberry Pi Christmas Project – Christmas House and Neopixel Snowman

Monday, December 17th, 2018

This year I’ve been creating a 3D model of a building for an outdoor model railway. Technically it’s a building for a weigh bridge rather than a house, but I’ve given it a Santa’s Grotto make-over for Christmas and so Christmas House sounds better. The building is designed in TinkerCAD based on a real building […]

TinkerCAD 3D Snowman for 3D printing G-Scale model railway

Monday, December 3rd, 2018

This is a model that I’ve made using TinkerCAD. A snowman designed for 3D printing on a home 3D printer. It’s been created to approximate G-Scale (1:22.5) for outdoor model railways. It’s also hollow so that you can insert an LED inside and have it light-up (assuming it’s printed with a light coloured PLA) so […]

Model Railway – designing a G-Scale building for an outdoor model railway in the garden – part 1

Saturday, November 24th, 2018

This is my first attempt at creating a proper scale model for 3D printing. In this case I am creating a weigh building in G-Scale. This has been a huge learning curve. I’ve since learned from some of the issues in the first model and so part 2 will improve on the techniques shown. The […]

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 […]

Raspberry Pi 6th Birthday – Birmingham Raspberry Jam 2018

Saturday, March 3rd, 2018

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). I have been to the earlier birthday celebrations, supporting workshops run by others, giving presentations and running workshops. For 2018 the birthday celebrations […]

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, […]

ESA European Astro Pi Project – Mission Zero – Code that ran on the International Space Station

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). My son joined with a friend (both aged 9 at the time it was submitted) to create a Python program that ran on the International Space station during February 2018. Here’s his […]
