Quint BUILDs is known for impressive, entertaining YouTube videos. Having previously relied on Arduino boards for microcontroller projects, his Knife Throwing Machine presented a new challenge due to the real-time calculations required to launch a knife at exactly the right trajectory for it to nail its target tip-first.
This is where the Teensy 4.1 came to the rescue, in order to provide the 18,000 steps per second required by the motors in use. See the resulting insanity in action in the video below, and then go behind the scenes in the video below that.
