Micro:Bit -The YoYo

myminifactory

This custom YoYo leverages two Micro:Bits to facilitate digital comparisons and potential interaction between them, alongside more conventional measurement experiments with Accelerometers to gauge speed and motion and analyze 'wobble'. Random Number Generators are utilized to investigate the generation of random numbers from each Micro:Bit. Experiments can be conducted to generate linear length during spins and explore pattern creation from LED's while spinning. The design consists of 7 parts, divided into three per side with a central connection known as the 'spin-ring'. Each part is securely held together using tight push-fit connections with locating points, measuring 68mm x 60mm in size. Two AAA batteries connected in series power the device, producing 3 volts, and require the maker to connect two power connectors - one for each Micro:Bit - and fabricate metal end-points for the battery holders. Printing this design should be relatively straightforward with some support required; however, it has not been printed yet due to its late entry, but results will be uploaded once printed and tested with a Micro:Bit if available.
