Hi! I'm Pavel Severov, and I'm tester of that device.
Author and owner is my neighbour. He don't want to publish his name, but you can see him on the video :-)
It is hard for him to describe step-by-step process of its building. He just want to share main idea of this device.
If you need to know additional technical details - please ask me and I will forward your question to the author.
Please see schematic diagram of the device. It is in Russian, but I will translate it into English if anybody will ask for this.
You can also see photo report from the author's studio.
