This week in CoderDojo Athenry, the other streams joined us at the start, as we began with a demo of the Raspberry Pi, a really interesting low-cost computer that has been brought out in the last year. It only costs about €30 for a basic one, to which you add a power supply (many mobile phone ones work on it), an SD card (instead of a hard drive), a keyboard and mouse, and connect it to your TV to get started.
We saw it running Scratch and Python programs, and a couple of them were passed around the room for everyone to examine.
We took the opportunity to learn about the main components in a desktop PC: how to identify them and what the function of each one is. We also saw the equivalent components in the Raspberry Pi.
After that, we returned to Mesh networking and the Chatty program that we started a couple of weeks ago, that not everyone had finished.
Here are my notes from the day (PDF format): CDA-S2-Challenge13-RaspberryPi-Demo.pdf
Ninjas who had finished the Chatty program and wanted to do more did work on a 2-player Rock-Paper-Scissors program. We didn’t have notes for this, but I showed the code and it is posted here: http://scratch.mit.edu/projects/cdathenry/3077050 (This is code for one of the players. Similar code is needed for the other one.)
