DIY Chronograph Demo
Channel: Charles Werbick
Date: 13/02/2016

Short demo of my homemade ballistic chronograph prototype. It uses 2 beam-break sensors separated by a fixed width to measure the speed of the projectile from an airsoft, airgun or paintball gun.

The microcontroller used is an ESP8266. It was chosen for it's 80MHz clock speed (and CCOUNT register.) Project details are here-  https://hackaday.io/project/9378-diy-ballistic-chronograph
