Disc Sander(remixed)

- Used an old WD(Western Digital) hardrive. Modified the plastic disc and sander box to make it ticker to fit on WD motors .Also provide with 6 holes instead of 4.
- Use also any normal cheap 6-10A esc(no opto with BEC,with full servo PWM leads) from old quad(drone) -servo PWM controlled

- Used a servo PWM generator in arduino programmed on a re-purposed old DIY rx with ATmega328.Or any setup with an ATmega328P(arduino promini,nano)

I used my own servo PWM generator code(one channel) but it can be used any arduino Servo code for one channel from internet
