The Micro-Synth
I’ve been making electronic musical instruments for a while now, and every step of the way they get more complicated, and harder to produce. Taking a break from the more intense synths, I wanted something simple, easy, and fun to build. Today I made a simple 555 timer synth with a twist – it’s smaller […]

The Arduino Controlled Laser Security System
An arduino that runs a simple sketch can become a laser security system. The hardware is pretty easy.

Circle-A-Sketch
This simple project uses an Arduino, a photoresistor, 2 potentiometers, and a resistor and uses basic serial communication between the Arduino and your computer. Basically, the user can draw by controlling two potentiometers (drawing knobs) and the photoresistor determines how dark the circle will be drawn.
