We’ve mentioned one way to take split-second photos, but if you have a few electronics skills under your belt, you can make a more advanced, Arduino-based version that responds to sound instead of pressure.
Instead of having to place your object on a pressure-sensitive plate, this model works on sound — so the action being photographed needs to produce some sort of noise — but it broadens the number of things you can shoot. It works in a similar way as our previously mentioned model, closing a circuit that sets off a camera flash when it detects a noise. It’s a pretty neat photo experiment if you have the necessary tools, so check out the video above for a more detailed explanation (and a few cool demonstrations).
