Kapanadze and other FE discussion

[AlienGrey]

Yes nothing like stretching a 'point' however the point that's being missed is a spark 'gap'
can also be used as a switch, as most semiconductors 'fry' as low or far lower than 2 or 3 kvolt.
there are a few other points that are being missed out as well when comparing the don smith
device with other soviet devices.

Let's continue the review of Kapanadze's video.

What do the sounds that occur during operation mean?

1. When turned on, the device makes a strong rattling sound, which then subsides.
The sound is very similar to the operation of a vibration pump at low outlet pressure. During operation, the vibration pump probably creates the necessary pressure in some container. In the absence of this pressure, the armature of the electromagnet of the vibration pump hits on the core. When a high pressure is reached, the vibration pump piston needs more force to move, and the electromagnet armature associated with it no longer hits the core during vibrations, so the sound becomes quieter.
In addition, a feedback system is possible. When the pressure sensor detects the required level, it controls the triac regulator, which reduces the amplitude of the oscillation of the pump electromagnet.

2. Strange sounds from the spark gap.

At first it works rarely and aperiodically. Then the spark gap fires more and more often. Then the device is stopped by the operator with comments from observers that "the device is broken".
The device most likely has a microprocessor control in a separate shiny metal box.
The control system check the parameters of the output voltage and current. If there are any problems: voltage drop, frequency change, too much current in the load - the control system automatically changes some parameters of the device.
It can be assumed that rare stimulating discharges in the spark gap are necessary for the normal operation of this version of the device.
Probably at the end of the video, some problems occurred in the device, for example, something burned out, or some kind of tube broke and the component stopped flowing in the amount necessary for work. The control system attempted to compensate for voltage or frequency drops in the load by applying voltage pulses to the spark gap more frequently, for example by charging a storage capacitor at a faster rate. But this did not help, since the defect was fatal and the operator had to turn off the device.

Or such a situation was specially programmed in the control system to show that the device is still imperfect and further development is required.

A transformer in resonance also has such a sound effect and transformer welding machines too.

Some other points, the Don Smith device operates at 35.1 khz, be aware that that is a sub sonic
frequency it's used in ultra sonic kleaners ( sub sonics can fry your insides ) nice eh!

A transformer in resonance also has such a sound effect and transformer welding machines too.

1. But in the aquarium, the sound of the vibration stops completely, and the bulbs continue to glow. How so? "Resonance" is over, but the lights are on?
2. You need a very bad big transformer so that it vibrates so loudly that the sound from the plastic case drowns out the conversation of the observers.
3. A large iron transformer of 2 to 5 kilowatts would weigh too much, more than 10 kilograms. It would be very difficult to lift this device with outstretched arms. This is not visible in the video.
