He explains in comment section how it is done. If true what I don’t understand is why the leds are the same brightness no matter how many he lights at one time. Seems to me that more in series would be dimmer.
He explains the "magic" is done with a powerful transmitting coil under the table and a receiving coil and Cmos gate circuit on each LED. The 9V battery might be connected only to the switches and not to the LEDs.
hi
thanks for replying
in some of videos, the person who does this video, touch some points of circuit with his finger and with this,some of the leds turn on/off.
can you explain to me what is the effect of touching with finger?
