Bodgers – More SenseHAT

Hello again Everyone.

This week we continued to play with the Sense HAT and as we’ve been mostly focusing on projects so far this year we took the opportunity to look at some of the theory behind programming.

We looked at how we use variables, loops and decisions in our programs and we also learned about algorithms. An algorithm is a set of rules we can use to solve a problem for example an algorithm to determine if a given year is a leap year. A year is a leap year if it is divisible by four, but not by one hundred, unless it is divisible by four hundred.

We then worked on a program which would allow us to “move” an LED around the LED matrix on the Sense HAT. You can run our code on the trinket.io Sense HAT emulator.

Dave will lead the group next week when he will cover some basic electronics.

Thanks.

Declan, Dave and Alaidh.

 

Bodgers – Prizes and Plans

It was great to see everybody back after the break.

I had a big box of goodies from the recent Raspberry Pi Pioneers competition. We got more swag for both teams that entered including some very nice badges and three really interesting books.

Our Zombie Trolls also got their prize for failing really well 😊. This included a Raspberry Pi, a 5” HDMI Monitor, some basic electronic components, t-shirts and an Astro Pi Sense Hat (Hat stands for ‘Hardware Attached on Top’).

The Sense HAT add-on board was specially created for the Astro Pi competition which gives kids the chance to get their code running on one of two Raspberry Pi devices that are on the International Space Station.Astro_Pi_Ed_and_Izzy_on_the_ISS

The board gives Astro Pi the ability to ‘sense’ and make many kinds of measurements, from temperature to movement, and to output information using a special display – the 8×8 LED matrix. We had great fun playing around with the Sense Hat and it’s definitely something we will get great use out of and maybe we could enter the Astro Pi competition and have our code running on the ISS.

We also took a look at controlling an Arduino from Unity 3D which is something that could be used for 4D/Immersive Technology type game.

See you all next week.

Bodgers – Pioneers Challenge Results

Hello again Everyone.

I didn’t realize when I posted yesterday that the results of the Pioneers Challenge were out today.

Here is the Raspberry Pi Blog post announcing the winners.

Congratulations to Barry, Kevin and Zack the Zombie Trolls whose project Zombie In The Middle won the We Appreciate What You’re Trying To Do prize. the following is a quote from the website.

“Playing piggy in the middle with zombies sure is a unique way of saving humankind from total extinction! We loved this project idea, and although the Zombie Trolls had a little trouble with their motors, we’re sure with a little more tinkering this zombie-fooling contraption could save us all.”

Well done to the three boys and well done to all the Bodgers because all the Pioneers teams helped each other out, most importantly at the beginning when we were trying to come up with ideas for our entries.

See you all in January.

Bodgers – Videos From The Pioneers Challenge and Robot Wars Bodgers Style

Last Saturday we finished up for the break with our Christmas party. We played video of the projects we entered in the Raspberry Pi Foundation’s Pioneers Challenge “Only You Can Save Us”. The challenge involved teams working on projects that would help people if there was a zombie apocalypse.

 

 

We then gave everyone an opportunity to have a go at a robot wars style game with our Raspberry Pi robots.

 

 

Happy Christmas  Everyone, we’re really looking forward to next year and building more cool stuff.

Declan, Dave and Alaidh.

Bodgers – Making More Progress

This weekend in the Bodgers Group our three Raspberry Pi Pioneers teams continued to work on their projects.

The Zombie Herders were working on a PIR (passive Infra-red) sensor which is the type of sensor commonly found in burglar alarms.

They used the GPIOZero library for Python and sample code which can be found here. However they didn’t have much success so we need to do more testing on our sensor and if necessary order a new one.

The zombie trolls worked on creating a 3-D model for their project using FreeCAD which they will print out when we return after the break.

I’m afraid I not allowed to discuss what it will be used for at this point :-).

Team Green Fingers worked on more scripts for their project including using their Arduino and a relay to switch a 12 volt automobile bulb on and off.

As with most projects like this we had a little trouble getting it going as we forgot to set the pin we used on the Arduino as an Output. Thanks to James and his Dad for bringing in the 12 volt powerpack.

We are off for the next two Saturdays and we’re back again on the 11th of November.

See you all then

Declan, Dave and Alaidh.

 

Bodgers – Making Movies

There was great excitement at this weeks session as the Pioneers teams opened their gifts from the Raspberry Pi Foundation. Each team member received a Raspberry Pi USB wristband, a Pioneers Lanyard, stickers and some sweets. Each team also got a copy of the Makers Guide to the Zombie Apocalypse and some zombie make-up.

We also got to see what was in our “Mystery Box” and I’m sure we are going to get great use out of it in future projects.

We then talked about the videos we’ll need a part of our entry and we had a look at a video from Pioneers on we need to put in our videos.

Then the teams spent some time planning out what they are going to do for their films.

Next week we are going to get back to working on our our projects.

See you then.

Bodgers – Making Headway

This week our teams started coding their their projects for the Pioneers challenge.

The Zombie Trolls and the Zombie Herders started by playing audio for their Raspberry Pi projects using Pygame.

The green fingers spent the session trying out sensors for their Arduino based project like this DHT11 temperature and humidity sensor. They also got a soil moisture sensor and a float switch working.

We also got some great news from Twitter before the session.mystery win

Here is a picture of the mystery box.

I don’t know what the mystery is, it looks like a cardboard box to me 🙂

See you all next saturday.

Bodgers – Getting Started On Our Projects

Hi again Bodgers

We started today’s session by looking at 3-D Modeling using FreeCAD. FreeCAD allows us to build complex 3-D designs using primitive shapes like cubes and cylinders. You can download FreeCAD from here and the video below will help you get started.

Our teams have finished deciding what they are going to work on for the Raspberry Pi Pioneers Challenge and they also have picked team names.

See you next week.

Bodgers – Make Your Ideas

Hi Everyone

We started today’s session with some information about the group and our plans for the year ahead.

We spoke about Digital Making, Digital Makers use technology to make something and learn about that technology while doing so. Technology available to Digital makers includes Raspberry Pi, Arduino, Fritzing, Sensors, Displays, 3D Printing and basic components.

Our Philosophy in the Bodgers group is that the most important thing is to get the project working. We don’t worry about how secure, how robust or how pretty our project is as long as it works long enough to show it works and that we understand how it works. We will use whatever resources we can get our hands on, online tutorials, online code, cheap components and cheap and easily available materials.

This year we will focus on projects, I will do some demos but there won’t be classroom type sessions. We would like you to work in teams. We will do one project between now and Christmas and another between Christmas and June. We would like everyone to work on the Pioneers Challenge between now and Christmas, after Christmas you can work on anything you want maybe Coolest Projects, Scifest or even PiWars.

We watched an excellent Video by @estefanniegg who takes a similar approach to project building as we do.

We then had a brainstorming session for the Pioneers Challenge and as you can see we had some great ideas.IMG_20170923_134312

We have narrowed down our ideas to a few projects and the mentors are busy trying to source materials for next week.

We will enter some of our projects next week and we might have a look at 3D printing software.

See you then,

Declan, Dave and Alaidh

Bodgers – ONLY YOU CAN SAVE US

Hi again Everyone

Hope you had a great summer.

I’m looking forward to another great year of Bodging. This year our focus is going to be mainly on projects and I’m hoping to use the Raspberry Pi Foundation’s Pioneers challenges for inspiration.

The first theme is… ONLY YOU CAN SAVE US!!!

A calamity of epic proportions is underway, and you and your team are the only ones who can save us! Can you create something that will protect the world during the apocalypse? What about something to avert the apocalypse altogether? Time to get your survival kits out and your thinking hats on, as you #MakeYourIdeas and save us all!

 

You can get more information here and there are some resources here

See you on Saturday, bring loads of ideas.

Declan
