Arduino Laser Show (adapted from NothingLabs’ Instructable)

This project uses an Arduino, a pair of speakers, and a laser pointer to create a laser projector able to trace out designs in a dark room. To power it, I've cannibalized a PC ATX power supply capable of delivering plenty of current for the speakers. Most of this project was directly adapted from the excellent Arduino Laser Show with Full X-Y Control by Rich Olson / nothinglabs. Step 1: The Big Idea Laser p ...

Arduino Laser Trip Wire

For this dandy little project you'll need: Arduino - I'm using an Arduino Uno a 3 x 4 keypad a 16 x 2 LCD screen a laser module/sensor a light dependent resistor (LDR) a buzzer 3 x 220 ohm resistors 1 x 10K resistor 1 x 10k potentiometer (optional, it's to adjust the LCD screen brightness) an LED and a ton of wires! So, first thing I did was to get the LCD and keypad working together. For this I pretended t ...

First germanium-tin semiconductor laser directly compatible with silicon chips

Swiss scientists have created the first semiconductor laser consisting solely of elements of main group IV (the carbon group) on the periodic table. Simply, this means that the new device is directly compatible with other elements in that group – such as silicon, carbon, and lead – and so can be directly incorporated in a silicon chip as it is manufactured. This presents new possibilities for transmitting d ...

Theremin w/Zapper,laser,Arduino using arduino

I created this Theremin like device after seeing this article in Make magazine: http://m-cdn.dashdigital.com/make/vol15/?pg=69#pg67 While this looked pretty straight forward it turned out to be a bit much for me at the time.  But after much effort, I got it to work pretty good. I had trouble getting the laser to aim correctly so I chose to mod a zapper I had available to hold the laser.  This worked well. S ...

Let’s go creative with lighting on a DIY laser device

Last year MediaInteractiveDesign and PlayModes , two interactive design and creative technology studios based in Catalonia, collaborated to develop a system to control DIY Laser robot. They created a new shield  to control Dinamyxel servomotors  to work with PWM laser drivers. The shield works using Arduino Ethernet programmed with a specific firmware to control laser and motor using Open Sound Control. The ...

BUILD YOUR OWN LASER HARP using Arduino

The laser harp is a musical instrument made of light. A fan of beams shoots up from the floor into the night sky. The performer can create music by placing their hands in the beams. Not only does “breaking” the beam produce notes, but sliding the hand along the beam will also change the sound. The harp does not produce any sound by itself, but creates MIDI data that can be connected to any modern synthesize ...

CatBot: Automated Cat Laser using an Arduino

The CatBot is an autonomous laser toy for your cat. You may say "But Joe, isn't the laser pointer the best toy for the lazy cat owner?" I'd have to say no, the CatBot takes one step further. Using two servos, an Arduino and a cheap $3 laser you can provide your cat with endless fun. Step 1: The Problem I was buying pet food and saw a $3 laser from PetCo. I thought the cat might like it. I was wrong. The cat ...
