In the hands of the device "Paracels 7" for the removal of worms. You take two contacts, hold them in your hands for 10 to 20 minutes and after a few sessions of worms as never before.

Inside, the PIC16F628 emits a signal with a frequency of 30 kHz and an amplitude of 4.5 V. Another leg flashes with a LED. Food from "Crowns" through Krenka. All... there is nothing else there. The price is 13,000 rubles. Also delighted was the memory card of the herbs, charged in the pop of this device and representing a piece of foil textilit. It closes the contact and lights up another blue LED, even past the PIC.
