Vacuum Tube Curve Tracer: remake of Tektronix 570

Measure vacuum tubes (triodes, pentodes) as they did in the 1950's with a remake of the Tektronix 570 "Characteristic Curve Tracer".

This Elektor-project from 2010 uses an EM84 magic eye to display the cpu usage of a pc. Great, but it doesn't work any more under Windows 10 :-(
