Homemade, not a commercial product. 

This measures about 5" W x 6” H x 8” D.

The clear acrylic shroud and the plexiglass base are homemade. 

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. 

Display also moves slightly every six seconds to help prevent "burn in" of the crt. The microcontroller 

and all chips are in sockets for easy replacement, and all the components are replaceable/repairable 

with some soldering skills and basic component identification. 

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.

Below are the operating instructions.  It can be set for operation on 

120VAC (U.S. standard) or 240VAC (some other countries) It is an entirely homemade novelty craft 

project from my workbench.

 Some points of interest:

• All the components on my clocks / kits are replaceable/repairable because they are all standard size, not surface mount. 
• The IC's or "chips" are socketed so they can also be replaced easily, by simply unplugging the chip and plugging in the replacement.
• In many cases, I will repair the clock free for any reason if you ship it back to me - i.e., if a 
• component fails or is damaged (except the tube(s))
• All of my clocks use standard electric service (do not need a separate power supply) and can be set for 120VAC (U.S.) or 240VAC
