    LED oscilloscopes can be cheap and fascinating tools to look at some curvy signals, but the resolution is so poor! When Dave decided to build an XY LED oscilloscope, he wanted to go bigger as well and solder up 400 10mm LEDs. With an XY oscilloscope, you can take a look at Lissajous figures and even watch oscilloscope music on it!
