Solid State Oscilloscope
It uses a matrix of 100 LED’s for a display, and does suffer from being slow and having rather poor resolution. Still we could display a sine wave running at 500Hz without trouble, that that’s not all that dissimilar to commercial solid state osscilloscopes.The circuit displays an understanding of the mechanics of displaying an analogue waveform. The timebase is simply a 555 generating a horizontal sweep, while the vertical amplifier is 3914 with a trimpot on the front. It’s extremely simple, but it works.
