Made in the USA. This is the first analog design which uses a circle generating sine wave oscillator

controlled through microcontroller to create the display from circles, arcs and lines.

Please note that the oscilloscope clock shown is for demonstration only, and the CRT 

and enclosure are not included in the kit.

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 transformer. 

It uses a simple low voltage dual secondary transformer and a line fed voltage multiplier for the HV.

I supply the instructions for assembly and a parts list with the board and components. 

Some CRT types that I have used with this board are: DG7-32, DG7-6, 2AP1, 2BP1, LB-8, 

6Loi1, 50HB1, 7SJ33J, 3SP1, B7S2, LO-247, 3GP1, 3Lo1i, 1EP1. 

Many other small relatively low voltage CRTs may work with the kit.

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.

It can be set for 120VAC (U.S. standard) or 240VAC (some other countries).

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.

Instruction set for scope clock

It can be set for either 120VAC or 240VAC, please see the small four pin header

marked 120> <240 and set the jumper on the appropriate two pins..

Instruction set for analog scope clock OSC4.9 

 When plugged in, the blue led should light immediately, and in five seconds, there should be a small "click" of the relay engaging. 

The neon light in the back should glow orange. After several minutes, the filament should warm sufficiently and the screen should 

display "1", (number one). This means 60HZ was detected and set accordingly. If a zero appears instead, then 50HZ was erroneously 

detected (unless your country uses 50HZ mains of course). Unplug, wait until the blue led goes off, and then plug back in.  

If the screen only displays a dot, or if the display is not well formed, you may need to adjust OSC SHAPE (P10). Using a small screwdriver,

turn the dial slowly clockwise until a circle appears onscreen. If the screen does not display anything after five minutes, unplug and wait 

one minute then plug in again.  

The time set buttons are a pair situated close together, one is slow set, and the other fast set. To set time without programming any preset 

on/off times, just press the slow set button (on the left) once and the clock display should appear, then use the two buttons on the front to set time. 

To set for Wifi/GPS: 

 When the “1” (or “0” for 50HZ) initially appears, press “toggle” once to select your time zone. 

Cycle through the time zones by pressing “fast set” to increment to the correct time zone (i.e, for EST = “01”) (Once selected, it will be stored in 

EEPROM, no need to select it again) 

When the correct time zone appears, press “slow set” once to return to set up. 

Press fast set once to enter date select screen. If choosing date display, press toggle once to select. 

Press fast set again to enter time keeping mode. 

The screen should display correct time. GPS modules may take several minutes to acquire a satellite lock. 

To refresh the data, press slow set & toggle simultaneously. 

To manually turn the display on/off, press the “toggle” button on the right side (separate from the two set buttons). 

To program the preset on/off times: First press slow set to enter normal timekeeping mode, then press the fast set 

& slow set buttons at same time and the screen should display 12:00:00. The seconds will not count in this mode. 

Press & hold the fast set button to increment the hours. Each time that button is pressed, the hours should increment once. 

When the desired hour is shown for ON time (AM only), press the toggle button to advance to the next screen and the display 

should change again to 12:00:00. Follow the same procedure, and after the OFF time is selected, either press slow set to enter 

normal timekeeping (fast set / slow set) mode or, to set the second set of preset on / off times, press toggle and follow the same 

procedure, except this time you will be selecting first a PM on time and then an AM off time. Please refer to the youtube link for 

illustration: Note: The clock will display 12:00 AM to start, so if the present time is after noon, you will need to advance the time 

past 12:00 in order to reach the PM hours, else the preset on/off times may be reversed. I.E.: if the present time is 8:00 PM, you 

need to advance PAST 8:00 once, and then stop at 8:00. 

To change the display mode, press fast set & toggle button together and the display mode will change to a “0” (zero). 

Press fast set to cycle through 0, 1 & 2. 0 is the alternating display (default), select 1 for digital only & 2 for analog only. 

Press slow set when you have made your selection to return to normal timekeeping mode. This will start again at 12:00 AM. 

To set DST (daylight savings):

Press fast set & toggle to enter display mode, then press toggle to enter DST mode.

Press fast set to change between 0 & 1.

0 = DST off (Spring to Fall)

1 = DST on (Fall to Spring)

Press slow set to exit & return to run mode.
