Jeri Ellsworth describes how she attached a floppy drive to a tape deck recorded and then played back audio. A simple circuit stepped the head automatically using the spindle index pulse. A push button was used to control the direction. The drive head wrote to more than one track at a time, causing an interesting reverb effect. ***Erasing the disk with rare earth magnets while spinning in the not mentioned in the video.
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.
