 Check out this cool DIY Arduino Oscilloscope which uses a cheap Nokia 3310 Screen which can often be found for $5 or $10. Watch the video below to see how surprisingly good this thing actually works!

 “The setup is really simple, connect an Arduino Pro Mini to a Nokia 3310 LCD screen, sample an analog port and then wright the pixels to the screen. I even added two potentiometers, one that adds delay to the sample to essentially provide a basic time scale and another pot that can scale down voltages as long as they are below three volts (the operating voltage of the micro controller). Unfortunately if you want to sample sign waves that have voltages over three volts you are out of luck unless you build an electronic circuit to scale it down somehow.”
