Owing to the recent launching in Europe of Cranial Electrotherapy Stimulation (CES) portable sets, we have been "Electronically Stimulated" in designing a similar circuit for the sake of hobbyists. CES is the most popular technique for electrically boosting brain power, and has long been prescribed by doctors, mainly in the USA, for therapeutic reasons, including the treatment of anxiety, depression, insomnia, and chemical dependency. CES units generate an adjustable current (80 to 600 microAmperes) that flows through clips placed on the earlobes.  The waveform of this device is a 400 milliseconds positive pulse followed by a negative one of the same duration, then a pause of 1.2 seconds. The main frequency is 0.5 Hz, i.e. a double pulse every 2 seconds. Some people report that this kind of minute specialized electrical impulses contributes to achieve a relaxed state that leaves the mind alert. Obviously we can't claim or prove any therapeutic effectiveness for this devic...

This is a very simple circuit of a bio-stimulator Muscular, which has indications for the treatment of cellulite. He sends little shocks through two electrodes, and should take great care when using the stimulator. The muscle stimulator circuit is based on a 555 timer IC. The transformer must be 220 volts to 12 100 to 150 mA and the circuit is connected in reverse. Muscular Bio-Stimulator for Treatment of Cellulite Circuit Diagram The IC 555 to generate pulses at 80 Hz and 150usec by the output voltage of the muscle stimulator device is about 60 volts to 150 volts, but the output current is very small and there is no danger of electric shock. The potentiometer P1 bio-stimulator sets the amplitude of the output pulses' and must be operated by the "patient", starting with the knob fully counterclockwise, then rotating it slowly clockwise until the LED begins to light up. The functional principles of the bio-stimulator is the same commercial bio-stimulator. Parts List: Linea...
