Let's Measure the Speed of Light (Part 2): The DIY Edition

This is a follow up video to "Let's Measure the Speed of Light" • Let's Measure the Spee... .
That video covers some of the history of determining the speed of light and then does an experiment to measure it using a Laser Diode as source of light pulses and and Photo Diode as a light pulse detector.
This video goes over further details of how to carry out the experiment yourself using as little as $300 worth equipment and parts. Other ways of generating a suitable series of light pulses for measuring the speed of light are also covered, including pulsed LEDs, Xenon stroboscopes, Laser Distance Measurer tools, and a light chopper made with a dremmel.
