solution – a capacitive touch screen with a fixed number of programmable buttons presented on a display. The screen was to consist of a set of capacitors etched into a film of copper on a sheet of glass‚ each capacitor being constructed so that a nearby flat conductor‚ such as the surface of a finger‚ would increase the capacitance by a significant amount. The capacitors were to consist of fine lines etched in copper on a sheet of glass – fine enough (80 μm) and sufficiently far apart (80 μm) to be invisible

Before reaching any of these portions of the mouse‚ however‚ the current must flow through a series of mica capacitors‚ electrolytic capacitors‚ and resistors. In this mouse‚ five capacitors (two mica‚ three electrolytic) and one resistor control the current to the LED. The mouse contains two contact switches (push button switches) at the front for the left and right buttons. The

The machine‚ due to its intended purpose‚ did not provide big fat arcs – however I think it’s still impressive and worth mentioning. Behold! High voltage enthusiasts‚ who are familiar with the classic NE555 flyback driver‚ will notice the foil capacitor across the primary winding‚ which really makes wonders. (More on this here.) The output voltage depends on the oscillator frequency (set it to variable 15-30kHz for output voltage fine-tuning)‚ number of primary turns and on the resonant capacity
