Electron Micrographs: The ‘Applied Science’ of Grooves on an LP
After watching earlier this week how vinyl records are manufactured, we were reminded of this great video by Ben Krasnow, capturing the movement of a record needle in the grooves of an LP using an electron microscope. (This video is probably well-known to many readers but it’s always worth a watch – and if you haven’t seen it already you will be overcome with happiness to imagine this is what is happening when you listen to analog vinyl records!)
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.
