HackSpace magazine #46

Anyone can be a scientist, and this issue we’ll show you how. Whether you’re interested in space, traffic, the oceans, or something else, there’s a citizen science project for you. The world has never been more connected – so let’s use that connectivity to make our planet better!

Also: We talk to a real-life scientist on the emotional links between making and materials, turn empty drinks cans and a bit of 3D printing into a heat-exchange system for a laser cutter, coax random numbers from a humble ESP32 board, make music with a Raspberry Pi Pico, build a glorious piece of retro tech in the shape of a crystal radio, and explore a whole bunch of other things to make and do.
