Justin Hyunh wrote in to share this cool project he and Chris Ladden built: a tweeting anti-shark laser security system! A laser pointer shines on a light sensor. An Arduino detects a low reading from the sensor and uses a BeagleBoard to send a tweet to @BruceSharkAlert and also sends a text message to Justin’s phone.
This may or may not have implications for real-life shark tracking, but Iโll take an excuse to have my shark tweet me when he (or she, Iโm no marine biologist) breaches the perimeter over to the sunny side of the tank.
Of course, Iโm doing this with my toy shark-on-a-stick and only a laser level and a light sensor, but itโs possible to make this much more accurate and granular just by adding more strategically placed sensors/light sources into the mix.
(In case you didn’t realize, this wasn’t meant to be a REAL shark detection system.)
