The short circuit is due to the VCC line being directly connected to GND. By removing the GND flag you can fix this. R9 should be moved so that it connects VCC with the RST line through the resistor. So one end of R9 should be connected to VCC, the other end to the RST pin.

The important point is that the HV terminal is high-voltage relative to the chassis (ground), not the Earth. The technician is discharging any voltage in the internal HV circuit.
Technically / ideally, if the device is not connected to mains earth/ground then you can touch any one point inside without a shock. (This is a bit light the bird on the high-...

Yes, this is the only(!) correct way of doing that. The CRT itself acts like a plate capacitor (and a very good one at that). The charge is stored between the inner parts of the CRT and its outer conductive coating - not between the CRT and earth. If you short the inside of the CRT (via the anode cap) against its outside (via the various grounding strips ...

The ground wire should not be connected through the breaker, and directly to the ground.
Connecting it through the breaker would be a safety hazard.

Of your drawn circuits, the last one with caps to GND2 will be best to shunt Common Mode noise. The one with caps to the common mode voltage will be worse, because you want to clamp the shield voltage to a low impedance node (e.g. GND)
However, the use of two physically separate cables for the LVDS lanes is questionable. You form a large loop, into which ...

One can often gain insight into the effect a resistor has on a circuit by thinking about what would happen if the resistor was increased to the point that it becomes an open circuit, and what would happen if the resistor were decreased to the point that it becomes a closed circuit.
Without knowing the exact circuit you are describing, I would assume that ...

By attenuating the Vin- feedback to be compared with the Vin+ The output must rise to match the Vin- input , thereby causing gain. The virtual ground occurs only if the inputs are equal when the output is not saturated at either rail then there is no gain if acts as a comparator.

It is not my intention to be pedantic. But I want to clarify a point just to make sure we are talking about the same thing. A PCB is a printed circuit board. By convention, it is usually called a PCB when it has no parts on it. So it is not static sensitive and does not have any special handling requirements. Sometimes a PCB will also be called a "bare ...

The most important thing is that you, and everything you touch, are at the same voltage. So if you're installing a PCB into a metal case, then touching the case will help.
Proper anti-static workstations have a conductive rubber mat, which is grounded through a high resistance (about one megohm). So if you connect a wrist strap to the mat, and place your ...

Isolation is your tool to make sure crazy currents don't trigger digital signals or mess with analog signals. Since it's "just" a drone, you don't need isolation same way it's required in industrial applications.
So to your question, if you can be sure you design the current flow such a way you don't get grounds bounced each time a motor is turned ...

The power must be supplied to all from the LiPo, with step down
voltage regulator on controller board... Will ground bounce be induced
if the ESC connectors are on one board, and the controller board is
completely separate?
If they are all supplied from the same power source than they cannot be completely separate. To prevent problems due to current flowing ...
