Improvised medical vibroacoustic device “Vitafon” is intended for the treatment of bronchitis, sinusitis, tonsillitis, arthritis, ulcers, open wounds, fractures, bruises, hemorrhoids. Acting contact method (with continuously changing the sound frequency) at a particular organ, the apparatus excites mikrovibratsiyu affected (and adjacent to the nidus) of the tissues, activates the healing processes and recovery. A fundamental principle is the same therapeutic effect, as shown by the results of the research is a local increase in capillary blood flow and lymph flow due to reduction of hydrodynamic resistance of blood vessels within the area of vibro-acoustic influence of waves of a certain range.

SHINE EVEN BLOWN
Inspired by the originality of technical solution, published in the journal “modelist-Konstruktor” No. 11’78, I modified the circuit for fluorescent lamps and for many years its use in residential lighting fixtures. As in the prototype, economical and not scarce ЛДЦ40 (ЛДЦ80) light up instantly, their work is not accompanied by annoying clicks and “wink” for missing an unreliable starter. And best of all — for such lighting you can even use the bulb.
SINCE THE BATTERIES “DO NOT PULL”
