These days, everyone is using USB memory sticks to transfer data from one machine to another. Or we are using CDs or DVD’s to install software. Well, sometimes at least.
Still remember the ‘old’ days where 3.5″ Diskettes were commonly used? Seems like these days are gone. So what to do with that hardware? Play music!
Each drive uses a Direction signal (80 steps are possible in one direction), a Step signal (performs a step on the motor) plus a low active Enable signal. Makes 8 times 3 signals plsu the 5V power supply for the drivers. The signals are generated with a National Instrument myRio board:
The drives are mounted on a wooden box as resonator.
And here a video of the system in action:
I’m thinking about using a tinyK20, store the music files on the SD card and I have an awesome music player :-).
Happy Driving 🙂
