Rotary Tool using brushless motor
thingiverse
This is a Dremel-like rotary tool that utilizes a brushless motor and an Electronic Speed Controller (ESC) for operation. A pre-programmed arduino board controls the speed of the tool in five distinct steps, allowing it to reach impressive speeds of 16,000 rpm. Motor and ESC details can be found at https://www.amazon.com/Hobbypower-1000kv-Brushless-Multicopter-Quadcopter/dp/B00E7LG85O/ref=sr_1_1?ie=UTF8&qid=1486392333&sr=8-1&keywords=2212+motor+combo A JT0 drill chuck, suitable for use with the tool, can be purchased at https://www.amazon.com/Electric-0-3-4mm-Mounted-Connecting-3-17mm/dp/B01AW7NDOA/ref=sr_1_6?ie=UTF8&qid=1486392393&sr=8-6&keywords=jt0+drill+chuck
