THIS IS A REMIX AND AN UPGRADE TO THE ORIGINAL JET ENGINE: https://www.thingiverse.com/thing:1327093 with the forward covers and ducting bits from: https://www.thingiverse.com/thing:4193487

This project implements many mechanical modifications to the original jet engine model paired with an Arduino and other electronics in the base to allow the user to get the main fan blade spinning up to 1700rpm! With a 12V DC motor and L298N motor driver, the rotary encoder on the front is used to control the speed from 60rpm to a user-set (and non-volatile) maximum speed. A 4-line LCD screen displays the current estimated fan blade speed, motor speed, and real-time measured voltage across the motor terminals. This project can be a great introduction into electronics if you are looking for a challenge, or a fairly comfortable build for the more experienced hobbyist.
