Made in the USA. This is the original, vector style version, OSC4.6 with updated "system font"
characters. For the OSC7.8 design, please see my other listings.
Please note that the oscilloscope clock shown is for demonstration only, and the CRT
and enclosure are not included in the kit.
This kit can be configured to drive larger CRTs, but this requires an additional 320VAC HV transformer,
which is not included, but can be added for additional $64 & additional $12 shipping.
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 OSC4.6:
______________________________
When plugged in, the blue led should light immediately, and there should be a small “click” sound of the relay engaging. The orange (neon) bulb should light.
After several minutes, the filament should warm sufficiently and the screen should display “1” (number one) for 60HZ (USA) or “0” (number zero) for 50HZ (some other countries).
Sometimes the wrong frequency is erroneously detected. In this case, please unplug the clock, wait until the led goes off, and then plug it back in.
To start in manual time set mode, press "slow set" button once, and the screen will enter run mode.
The time set buttons are a pair situated close together. One is fast set and the other is slow set.
The toggle button is on the side. Press this once and hold for one second to toggle the display on/off.
To manually turn the display on/off, press the toggle button (separate from the two set buttons).
************************************************************************************************************************
Selecting timezone and date mode on/off and GPS / Wifi auto set mode (if equipped):
Note: In most cases the time zone has already been set by default so the following step will not be necessary for most.
To select your time zone (if using GPS or Wifi autoset) you must start from the startup screen (number “1” or “0” displayed after plugin)
If the clock is plugged in already, unplug it to start this procedure.
From the start screen ("1" or "0"):
Press the toggle button once to select the timezone, please refer to the list below to find your timezone number..
Press fast set to increment through the selections to choose the number for your time zone.
Press slow set twice to enable the time zone selected and return to setup.
To enable GPS / Wifi autoset (if equipped), press fast set once and the screen will momentarily blank and then display “0” or "2".
If enabled, the date will display on seconds count 50-53.
Press toggle to change the selection between 0 and 2.
0 = no date displayed
2 = date displayed
When your selection is displayed, press fast set twice to enter GPS/Wifi set mode.
The display will be "3" while the module is searching for satellite or network.
When data is found/ locked, the screen will enter run mode.
*****************************************************************************************************************************
****************************************************************************************************************************
To set up the WifiModule (if equipped), please follow these steps:
Connect to the network named "WifiModule" on your device (you may need to first disconnect from other networks)
Open your browser and type "192.168.4.1" in the address bar. This should open the webpage
WifiModuleConnect, where you can enter your SSID (network name) and password.
Click "submit" and the module should connect and the clock should display the time.
SSID & password will be saved.
To erase the network (if a SSID & password is already saved), press the reset button on the module and power the clock down and restart it after ten seconds.
*********************************************************************************************************************************
*********************************************************************************************************************************
To program the preset on/off times:
Press the fast set & slow set buttons at the same time, and the screen should display the clock face without hands.
Press the fast set button again, and the hours hand should appear. Each time that button is pressed, the hours hand should increment once.
When the desired hour is shown for ON time (AM only), press the slow set button once to confirm, and the colons (dots) should appear. This indicates the ON time is set.
Press either button once to enter the OFF time set mode.
Follow the same procedure, and after the OFF time is confirmed (colons appear), 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 fast set and follow the same procedure, except this time you will be selecting first a PM on time, then an AM off time.
Press either button to exit sleep/wake and enter run mode.
To erase the preset times:
Follow the same procedure as in setting up the times, except just select 12:00 each time and move on until the on / off times are all set to 12:00.
Note: If the GPS autoset is not enabled, 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.
If GPS autoset is enabled, the correct time will set automatically at this point.

*********************************************************************************************************************************
Display modes:
To set the display for digital only, analog only or alternating:
Note: This is only included in the gps/wifi program, which is the 18f2685 PIC.
Press slow set & toggle buttons simultaneously.
Press fast set to cycle through the options,
0= alternating
1 = analog only
2 = digital only
3 = big digital
When your selection is shown, press slow set to set & it will return to ‘run” mode.
