Rendering 3D Graphics On An Oscilloscope
In this video, we're learning how to draw on an oscilloscope. By utilising the X-Y mode of the scope, combined with some clever firmware to generate the right signals, and a sprinkle of DIY digital-to-analog conversion, we can render animated 3D graphics on a scope in real time!
