0

Hello again everyone.

In the Bodgers group we’re starting to put our projects together for the Coolest Projects Showcase.

“Coolest Projects International is a world-leading showcase for young innovators who make stuff with technology. If you’re up to 18 and you’re making something with technology for fun, to solve a problem, or as a creative outlet, then we want you to come out and share your project with us! This free event will take place in the RDS Main Hall, Dublin, Ireland on 5 May 2019.”

Find out more here: https://coolestprojects.org/

If you have any questions you can contact me at coderdojoathenry@gmail.com.

Don’t forget we’re off for the next 2 weeks, we’re back on 27-Apr-19.

see you all then.

Bodgers – FreeCAD and Fritzing

Hello again everyone

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.

Hello again everyone.

This week we started getting our entries ready for the Astro Pi Mission Zero Challenge by looking at whose aboard the International Space Station now and what they’re doing. We followed this up by taking another look at programming the Trinket Astro Pi emulator.

We also had a small brainstorming session to come up with ideas for projects that we will be working on for the rest of the year.

See you all next Saturday.

This week in the Bodgers group we looked at controlling motors and robots withe the Raspberry Pi.

You can find the code for this weeks session here and my notes are here motors and robots

We also talked about ideas for the projects we will be working on for the rest of the year. Tomorrow we will continue to look at robots and we will also do some brain-storming for our projects.

See you then.

Bodgers – Traffic Light with Buzzer

This week we continued working with GPIO Zero, at the end of last week’s session we had started working on a simple LED traffic light, we finished of that this week and we added a buzzer to it.

I had hoped to work on the HC-SR04 distance sensor but there seems to be an issue with them on the Raspberry Pi at the Moment.

Here is a video that demonstrates what we covered on Saturday.

See you all next Saturday (08-Dec) for our Christmas party.

Bodgers – Introducing Gpio Zero

Posted on by

0

Hi again everyone.

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.

I don’t have any slides this week as we worked directly from the GPIO Zero Documentation available at https://gpiozero.readthedocs.io. This is also available on Dropbox, along with this week’s code and a sheet that contains a drawing of our circuit and drawing of the GPIO pin layout, here: https://www.dropbox.com/sh/k26mbrfmdvq9tro/AAB5jfjkIlBqLhfnUAVVUvtJa?dl=0.

See you all next Saturday.

Bodgers – Finishing Our Game

Hi again everyone.

This week we put the final touches to our game.

We added some code to increase the speed of the alien sprite as the score increased to make the game a little more difficult.

We then added some code to control what happens when the game is over.

You can find our code on Dropbox here: https://www.dropbox.com/sh/ccfaycpa1zluh8l/AAAA4dQH8EPNJicsQj7RwGgsa?dl=0

Next week we will do a quick recap of this game and then we will start looking at hardware on the Raspberry Pi.

See you all then.

Bodgers – Making a better game

Hello again everyone.

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.

I don’t have any slides this week but the code for both versions of the game are available here: https://www.dropbox.com/sh/ccfaycpa1zluh8l/AAAA4dQH8EPNJicsQj7RwGgsa?dl=0

See you all next week.

Bodgers – Making Pictures With LEDs

Hello again everyone.

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.

Bodgers – Making With Trinket.io

Hello again everyone.

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.

Capture15

The online emulator is available at https://trinket.io/sense-hat and there’s a good tutorial on the Raspberr Pi website here https://projects.raspberrypi.org/en/projects/astro-pi-mission-zero.

Here is our Trinket https://trinket.io/python/04b90b70cf.

You can play around with these and we will probably finish up with the Mission Zero Challenge for while after Saturday. My slides from last Saturday are here day 3.

See you all on Saturday.
