Decrypt Messages and Calculate Pi: New OctaPi Projects

via RaspberryPi.org

Back in July, we collaborated with GCHQ to bring you two fantastic free resources: the first showed you how to build an OctaPi, a Raspberry Pi cluster computer. The second showed you how to use the cluster to learn about public key cryptography. Since then, we and GCHQ have been hard at work, and now we’re presenting two more exciting projects to make with your OctaPi!

These new free resources are at the Maker level of the Raspberry Pi Foundation Digital Making Curriculum — they are intended for learners with a fair amount of experience, introducing them to some intriguing new concepts.

Whilst both resources make use of the OctaPi in their final steps, you can work through the majority of the projects on any computer running Python 3.

Calculating Pi teaches you two ways of calculating the value of Pi with varying accuracy. Along the way, you’ll also learn how computers store numbers with a fractional part, why your computer can limit how accurate your calculation of Pi is, and how to distribute the calculation across the OctaPi cluster.
