Interesting build for a USB microscope

Simple kit to make your own magnetic stirrer

Nice build, the case is 3D printed, and the electronics are all sourced parts. Figure this would cost about $10-15 dollars each. That said I got curious and looked to see if I could get one already made for less. … Continue reading

Nice build for a prototype board for Micro:bit
