Programming a message on a Microbit with a joystick

Reminds me of doing this on TV remotes, the author basically uses the joystick to go thru the alphabet and click the letter to select, then click end and the word gets “scrolled” by. https://www.instructables.com/BBC-MicroBit-Joystick-Keyboard/

Spooky eyes with a Micro:bit

Micro:bits are nice little controllers for teaching with kids. The author basically use them to make glowing “blinking” eyes. I like the use of hot glue to diffuse the light. https://www.instructables.com/Microbit-Glowing-Halloween-Eyes/

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

Simple “shield” for tutoring students

Its a simple plexiglass stand for a teacher to put between them and the student for tutoring. Nice build overall, I think the author should put a handle on it too so it can be carried around. https://www.instructables.com/id/DIY-Teacher-Desk-Shield-for-Writing-Conferences/
