An Oscilloscope Clock made with a 5” rectangular CRT (cathode ray tube).

Fully assembled version; not a kit.

Embedded wifi module.

Homemade, not a commercial product.

This measures about 6.5" W x 7” H x 14” The case is homemade from plexiglass. The board has pots to adjust vertical & horizontal height/width, focus, astigmatism, brightness, and vertical and horizontal centering. Automatically sets for 50/60HZ. The display alternates every ten seconds between digital and analog style. The display also moves slightly every six seconds to help prevent "burn in" of the CRT. The microcontroller can be exchanged (it is socketed) and all components are replaceable/repairable, as opposed to modern electronic devices which are basically "throwaways". This "old school" tech has been salvaged from obsolescence by marrying it to new digital tech. It is an entirely homemade/handmade product, including the base and shroud, which I thermoform from plexiglass stock, and the firmware the microcontroller is programmed with, which is my own original code. It can be set for 120VAC (U.S. standard) or 240VAC (some other countries.)
