Undergraduate uses Arduino to streamline high-speed photography

Wednesday, February 11, 2015

Cornell ECE student Ope Oladipo ’17 recently created an Arduino-based project that triggers a flash when it hears a sound above a certain threshold. Built and tested over the summer with the help of Senior Lecturer Bruce Land, Ope further tested his device over winter break, leading to the creation of this photograph. The delay is set via a computer, which in this case, turned out to be 100 ms.

“I became interested in photography about three years ago, and I’ve been taking high-speed photographs ever since, mainly because I thought it was cool and felt surreal,” said Ope.

A problem with taking high-speed shots is timing. His initial photos were taken by trial and error—he’d spend hours setting up the scene and even more time trying to create the picture he envisioned in his head. Now, after building and implementing the high-speed flash sound trigger, he only has to spend his time setting up.

“I think it’s great to be able to combine my knowledge from ECE and photography together to develop a more streamlined technique of taking high-speed pictures,” said Ope. “I hope to continue to apply my ECE knowledge to future projects and create photographs that are even more interesting.”
