How to make Simplest ever Oscilloscope Clock

Get 10 pcs of 2-layer 100x100mm PCBs in purple for only $5 - https://www.pcbway.com/?from=MirkoP
This time I decided to make an Oscilloscope clock in the simplest possible way. It even avoids the use of a mains transformer which is expensive and difficult to obtain, and initially the device works on 12V. But despite its simplicity, it is fully functional, highly adjustable, and has the option of automatically setting the time via the Internet. So it even outperforms more complex devices of this class.
SAFETY NOTE: Please do not attempt to recreate the experiments shown on this video unless you are familiar with High Voltage Safety Techniques! Direct Current even above 60V maybe lethal, even when the AC supply voltage has been disconnected due to the stored energy in the capacitors. I have no responsibility on any hazards caused by the circuit. Be very careful. This is a humble request.
