Oscilloscope clock made with 5" flat faced cathode ray tube similar to a 5CP1Designed 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.

This is a 5" CRT, similar to a 5UP1. View it on youtube at my channel "howchon" Oscilloscope clock on 5" CRT OSC7.1 - YouTube This is my newest version, OSC7.1, with a built in Wifi connection for automatically extracting the time, day & date from network time servers. This is designed to drive 5" or even larger CRTs and many types can replace this one, such as 5UP1, 5CP1, 3ACP1 3BP1, 3FP7, 3JP7, 3WP1, 3WP7, 5BHP2A and other similar types. Homemade, not a commercial product.
This measures about 7.5" W x 8" H x 19” D.
The clear acrylic shroud is not attached, but sits loose on top of 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
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
Below are the operating instructions. I will ship it anywhere in the world, but I cannot be responsible
for problems and/or delays caused by customs in your country.
International buyers, please send your address for a shipping quote. 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. Obviously, it is a novelty item meant for entertainment only, and since it is homemade, user discretion is strongly advised.
Some points of interest:
All the components on my clocks / kits are replaceable/repairable because they are all standard
size, not SMT
The IC's or "chips" are socketed so they can also be replaced easily, even by the layman
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 most
can be set for 120VAC (U.S.) or 240VAC (others)
