I was away this weekend so Dave looked after the group.
He covered some basic electronics theory such as Ohms Law, how we use resistors in our circuits to protect other components and how to wire up an LED. He also helped the group build a simple traffic light circuit controlled by an Arduino which they then programmed.
The Raspberry Pi Foundation have announced that they are not running the Pioneers Challenge this year and are instead concentrating on the Coolest Projects. This means that Coolest Projects is now open to Code Club and Raspberry Jam members. There will be a UK Coolest Projects in April in London and Coolest Projects in Dublin will now be called Coolest Projects International. See more info here.
We have two sessions before the mid-term break so we will concentrate on coming up with ideas for our next projects and how we might implement these ideas and that will leave us a couple of weeks to get components etc. organized.
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.
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.
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.
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.
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
This Saturday the Bodgers group looked at some of the tools available to set up and use the Raspberry Pi or Arduino at home. We looked software for formatting SD Cards, some of the SD card images available for the Raspberry Pi, putting images on SD cards, configuring the Raspberry Pi and connecting to the Raspberry Pi.
We also did a quick overview of the Arduino IDE. This software allows us to write and upload software to the Arduino.
You can find the links to the software we used short tutorials on how to use them in my slides from Saturday here pi-and-arduino-tools.
We also took a look at the MagPi Magazine which is the official Raspberry Pi magazine. there are a load of interesting articles in the Christmas issue which is in the shops now or is available for download for free from https://www.raspberrypi.org/magpi-issues/MagPi52.pdf . There are a few nice articles on basic stuff like breadboards and GPIO Zero and there are also some articles on robot sensors which anybody who wants to continue from where we left off with robots will find very interesting.
There is also news of a new programme from the Raspberry Pi Foundation which is aimed at kids that are around the same age as the Bodgers group. The Pioneers is a series of challenges that will roughly last the length of the school term and will be open-ended to allow you to come up with your own ideas. Unfortunately the competition is limited to the UK for now but it will be open to the rest of the world soon. Check out The MagPi for more information.
The MagPi needed to show some examples of what kids can make for the Pioneers article so obviously they looked to CoderDojo Athenry for inspiration :).
