Made in the USA.
This is a new design that displays the font style as century, instead of the previous version which displayed
hand drawn numbers. Built in wifi option can be used to set time & date via network connection.
This kit is the upgrade to the OSC7.8 kit that will drive larger CRTs using higher voltages, such as 5UP1,
5ADP1, 5BP1 and similar and also even larger 7" & 8" CRTs. It includes a high voltage transformer.
Please note, the CRTs are pictured to give an example of the font in this new design, a CRT is NOT
included with the kit.
Please see the video instructions for setup: https://www.youtube.com/watch?v=oXqGBzmSzus&t=78s
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 toroidal transformers.
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: 5UP1, 7VP1, 5ADP1, 5ABP1, 7UP1, etc.. Many other 5", 7" or 8" 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.

Instructions for OSC7.0:
When the scope clock is plugged in, the blue led & the small led on the module should light immediately.
To set time manually, press the "slow set" button and hold up to three seconds until the relay clicks and the
neon bulb lights.
The relay should click on, neon light should light, and in a few minutes the screen should display time.
Press slow set button again to start, and use fast set & slow set to set the time.
Toggle button will toggle the display on & off, just press once.
To connect the clock to your network via wifi, start from power on, unplug and wait a few minutes if it's
already powered on.
From power on (blue led & led on module lit), press & hold "toggle" button 3 seconds to enter AP mode.
Use your device to look for the AP "WifiModule" on your networks.
Connect to this AP, and when connected, open your browser and type "192.168.4.1" in the address bar.
Enter your network name or SSID and your network password.
Click "Submit" button and the confirmation page should appear.
Within a few minutes, the clock should connect to the network and the neon bulb (high voltage) should light.
If the clock doesn't connect after several minutes, try resetting the chip by pressing the miniature button on
the ESP32 board marked "EN" or alternatively, just unplug the clock and wait a few minutes, then plug it back
in and it should connect.
The time should appear. If incorrect, press the "fast set" & "toggle" buttons simultaneously to refresh the time.
From the clock face screen, press slow set & toggle simultaneously to display the day & date.
From the date screen, press fast set to return to the time screen.
From the date screen, press slow set & fast set simultaneously to enter the Menu screen.
In the Menu screen, use fast set to select the line indicated by the arrow, and use slow set to
change the selection.
When the Menu settings are correct, press toggle once to exit and return to the clock face screen.
From the clock face, press fast set & toggle simultaneously to refresh the time.
To set the sleep/wake times, press fast set & slow set, and the screen will appear for setting the "on" time.
Use fast set & slow set to choose the display on (wake) time.
Press toggle once to enter the "off" time screen.
Fast set & slow set to select the off time, and toggle once to exit to clock face screen.
