Oscilloscope Clock Kit for many CRT types. OSC7.0 includes the pc board, transformer and components to populate the board.Designed by Oscilloscope clocks in United States of America
This is a store featuring my homemade electronic novelty clocks, made using obsolete electronic tubes, and my kits designed for diy for these clocks.

The kit I have available is a professionally made pc board and the components to populate it, including the ICs and the preprogrammed microcontrollers written with my firmware, and the transformer. Please note that the CRT is NOT included with this kit. Also, the enclosure is not included. OSC7.0 uses a toroidal transformer to reduce EMI. This version is a new design that uses a faster microcontroller to draw the display from "pixels" similar to a raster. The display is drawn as the "century" font style, scanned directly from the font type, instead of the hand drawn numbers in the original design. I supply the instructions for assembly and a parts list with the board and components. You can download the Documentation, Datasheet and BOM from this page. The kit includes the following:

The video demonstrates what the kit looks like built with a DG7-6 CRT & homemade clear enclosure. CRT & enclosure are not included with the kit. Some CRT types that I have used with this board are:
Many other small relatively low voltage CRTs may work with the kit.
A video demonstrating some of the functions can be seen at:
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 and all chips are in sockets for easy replacement.
It can be set for 120VAC (U.S. standard) or 240VAC (some other countries).
