The Optical Tremolo Box was inspired by Charles Platt’s “Stomp Box Basics” article (MAKE Volume 15, page 82), which theorized using a light sensor to read patterns on a rotating disk to create a tremolo effect.

DIY Hacks & How To’s: Laser Tripwire Alarm

DIY Hacks & How To’s: Laser Tripwire Alarm

No security system is complete without lasers. We have all seen movies where the main character has to get past a high tech security system and there is always a room full of lasers somewhere.

With this you can cover an entire house with an array of light beams. If any one of them is crossed it sets off your alarm. And unlike in the movies, these lasers are practically invisible.
