This is a store featuring my homemade electronic novelty clocks, made using obsolete electronic tubes, and my kits designed for diy for these clocks.

A clock made using a 3" B7S-1 cathode ray tube (CRT), homemade enclosure with wifi connection & GPS option

OSC7.8 displays in "century" type font and has built-in wifi connection. We used alligator clips to connect to the CRT on this one which would make it easier to change out. A Mini Oscilloscope Clock made with a B7S-1 3" round CRT (cathode ray tube). Optional GPS module for time / date set.

Homemade, not a commercial product. This measures about 5.5" W x 6" H x 10" D. The clear acrylic shroud is attached to the plexiglass base. 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.) Obviously, it is a novelty item meant for entertainment only, and since it is homemade, user discretion is strongly advised.
