5" Oscilloscope Clock CRT Cathode ray tube scope OSC7.8 auto time date

Description: MADE IN THE USA OSC7.8This is a 5" diameter CRT. It has a Roman numeral face option, as well as 24-hour digital option, as shown. This is my newest version, with embedded Wifi connection for automatically extracting the time,day & date from network.It also includes a GPS module as an alternate method to extract time & date from satellite. It also has a menu option to display the Roman numeral face as in the 5" clock.Homemade, not a commercial product. This measures about 8" W x 9” H x 19” D.The clear acrylic shroud and the plexiglass base are homemade. 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 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, 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 original code.Below are the operating instructions. 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. Some points of interest:All the components on my clocks / kits are replaceable/repairable because they are all standard size, not surface mount. The IC's or "chips" are socketed so they can also be replaced easily, by simply unplugging the chip and plugging in the replacement.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 can be set for 120VAC (U.S.) or 240VAC (others) _________________________________________________________________________________________ Instructions for OSC7.8: When the scope clock is plugged in, the blue led & the small led on the module should light immediately. ****************************************************************************************************************************** GPS mode: If the clock is set to GPS mode (default), the relay will click on within three seconds and the neon bulb will light. Run mode will appear when the CRT is warmed up and time will start. If equipped with the GPS module, the module will search for satellite signal, and will blink once per second when a strong lock is obtained. The time can be refreshed by pressing and holding fast set & then toggle, and then release both buttons. This can be done as necessary to refresh the time until the correct time & date are obtained from satellite signal. Time will automatically refresh from GPS at 12:00 & 24:00. (In the menu, select WIFI GPS for this mode.) ******************************************************************************************************************************** ********************************************************************************************************************************* Menu mode: To change the mode between Wifi, GPS or manual, please access the menu by unplugging and holding down on fast set & slow set buttons while plugging in, and hold for three seconds or until the relay clicks on. The menu looks as: >FREQ 60 (frequency 60HZ or 50 for 50HZ) TIMEZONE 1 (please select time zone from list below) DST ON (daylight savings time, select on or off) WIFI ON (select WIFI ON for wifi mode, WIFI OFF for manual, WIFI GPS for GPS mode) ALT (select clock display mode, alternating, digital, analog, Roman numeral, 24 HR.) In the Menu screen above, 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 and hold for two seconds to exit and return to the run screen. ************************************************************************************************************************************ ************************************************************************************************************************************ WiFi mode: First set the WIFI to WIFI ON in the menu mode. 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. While pressing & holding the "toggle" button, plug in and hold for four seconds and then release 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. This should pull up the Wifi module connect page. Enter your network name or SSID and your network password. PLEASE NOTE: White spaces in the network name and/or password may cause connection issues. 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" button and hold and press the "toggle" button and then release to refresh the time. To erase the network name & password, press and hold toggle button while powering the clock on, and release after four seconds. Wifi should go into AP mode, allowing connection to enter new credentials. From the run 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. From the run screen, press fast set & toggle simultaneously to refresh the time. ****************************************************************************************************************************************** ****************************************************************************************************************************************** Sleep/wake mode: To set the sleep/wake times, press fast set & slow set, and the screen will appear for setting the "on" time. Use fast set to choose the display on (wake) time (hours only). Press toggle once to enter the "off" time screen. Fast set to select the off time, and toggle once to exit to run screen. Please note that in order to program a PM "off" time, you will need to pass 12:00 to get into the PM hours. ****************************************************************************************************************************************** ******************************************************************** Manual mode: For this mode please select WIFI OFF in the menu mode. When manual mode is selected, the display will go to run mode (clock face) or "Oscilloscope clocks" 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. ************************************************************************ Time Zones : 1 = EST 2 = CST 3 = MST 4 = PST 5 = AKST 6 = HAST 7 = BST 8 = CEST 9 = MSK 10 = PHT 11 = ACST 12 = GST 13 = AEST
