Shield against Communication.

I've shielded my PC for the perfect language study in order to emit no electric-magnetic field. I succeeded to obtain no communication PC, as perfect standalone.

Fig.1.

Fig.2.0. The side panel over CPU cooler. But the bottom side ventilation capability is down to 50%, therefore I use another small electric fan with dry cells.

Naturally, ventilation for CPU cooler and the power supply is working.

Fig.2.1. Outer-side shields. Also the ceiling has been shielded.

There is outer electric-magnetic shield which is 20cm far from PC, it makes the air flow enough. Heat destroys any computer especially CPU (central processing unit).

Fig.3. In fact, 0 μTesla and 0 Volt/Meter.

Fig.3.2. My PC for the perfect language, no outward appearance is smart.

Fig.4.

About in 2019, I scanned my DVD recorder, then the recorder emitted 138 Volt/Meter in spite the device was unplugged from a wall socket. See fig.4.

A minimum radio communicator requires 7 resistances and 9 condensers and an antenna as faked as earthing (grounding). Naturally if it is from inside PC, additionally a device controller is required.

I needed a safe computer, but if the device is installed by anyone like fig.4, it is too small to find, because of present technology.

Therefore I've shielded my PC.

I could bought the electric-magnetic shield from Amazon, it is made in China, $10 for two sheets, and 3 hours was required as my work.
