The time-gate project was a simple Arduino add-on project which made it possible to measure time-intervals of a passing projectile in time increments of 100 nsec. And to make the project a little more challenging, the projectiles involved were potatoes. Yes, potatoes.

This project would be an excellent choice for a science fair project or high school science/physics class in general. It entails electronic design and fabrication, laser diode emitters and detectors, fresnel lenses, microprocessors (Arduino), LCD display, and writing C-like software for the Arduino. And it is a crazy amount of fun to say the least!

A fairly detailed description of the electronic/mechanical design can be found in Part I with actual test measurement results found in Part II.

The Arduino chronograph assist can be provided fully assembled or in kit form. Contact sales@am1.us for additional details.

CAUTION! Only use compressed-air potato cannons rather than any combustible explosion for sake of both fire hazards, and the precise control of maximum pressures everywhere in the cannon!
