This week we continued working on our Astro Pi entries and we also looked at FreeCAD and Fritzing which are tools that will help us with building our projects.
FreeCAD, available for download from here, is used for 3D modelling and allows us design very complicated things from simple 3D shapes such as cubes and cylinders. Here are a couple of quick videos to get you started.
Then we looked at Fritzing, download from here, an application for drawing very easy to understand circuits, here’s how to draw a simple circuit using it.
Dave will be leading next Saturday’s session and I will see you again on the ninth of Feb.
This week we started looking at physical computing and the Raspberry Pi. This involves attaching various components such as sensors, motors or controllers to the GPIO pins on our Pi. This week we connected a LED and two buttons, and we used the GPIO Zero module for Python to control them. I’ve made a video, it’s a little bit long, that covers everything from Saturday’s session.
At the end of the session the group started working on a traffic light idea and we will combine this with HC-SR04 ultrasonic distance sensor next week to create a measuring device.
We continued working with Pygame Zero this week, we began by getting everyone up to date with where we were with the game. I forgot to mention we were following the tutorial at https://pygame-zero.readthedocs.io/en/stable/introduction.html. We then changed the screen size and added a score to make our game more fun.
Next week we will add some elements to make our game more difficult and even more fun.
This week in the Bodgers group we started working with Pygame Zero. Pygame Zero allows us to write our own games quickly and easily by doing a lot of the work involved in setting up and running a game in the background. This allows us to focus on the more creative aspects of the game.
You will have to install Python and Pygame Zero if you’re going to use Pygame Zero at home, details on how to do this are in my slides. A few of us had installation problems on Saturday, so don’t worry if you have issues we will help sort it out when we return after the break.
We started of this week’s session by looking at the recent Soyuz rocket launch which was to send two people to the ISS. During the launch one of the booster rockets failed and the launch had to be aborted. Both crew members, astronaut Nick Hague and cosmonaut Aleksey Ovchinin, escaped without injuries.

We then continued to work on our pictures and messages for the Mission Zero Challenge. I made a video of some of the work we did, but it’s very hard to film LEDs so the quality is very poor.
If you want to find out more about the Soyuz incident and have another look at how to make pictures and messages with the Sense-hat LEDs my notes are here day 4.
Next Saturday we’ll start looking at Pygame Zero. See you all then.
In the Bodgers group, we’ve been working on code for the International Space Station. To do this we are using on online Sense Hat emulator, the Sense Hat is a special piece of hardware designed to be deployed with a Raspberry Pi on the ISS.
Hello again everybody.
This week in the Bodgers group we started working on our code for the Mission Zero Challenge.
We began by writing a simple text message on the 8×8 full-colour LED display, then we changed the text and background colours. We then coded a picture by assigning a colour to each of the 64 LEDs on the display. We finished the session by taking a quick look at using the temperature sensor to read the temperature. Here are my slides from this week day 2.
Next week we will recap what we covered this week and we will start to personalise our code for the challenge.
In the meantime, here’s a couple of fun videos on how the Astro Pi computers got to the ISS.
