I love hearing about the journeys pupils’ projects have taken them on, so I thought I would share one of my own.
At the end of last year I put together a little code machine in Scratch (you can see it here), it used a simple Caesar cipher to allow you to send secret messages. This got me into reading a great many books on codes and it wasn’t long before I wanted to create an unbreakable code of my own.
I also met a few people along the way, including someone at the Secret Army Museum who discussed with me methods to check whether a coded transmission had been tampered with. All really interesting.
I have now packaged up what I’ve learnt and built an app titled The Code Machine, soon to be available for free so all can enjoy.
