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!
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.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
