This article is a biological muscle stimulator introduction. The principle of combining text comprehension is a good suggestion. The principle is very simple but very practical and effective. The biological muscle stimulator has a very effective and safer way to adjust the output amplitude. Fine adjustment of the "pulse" and "pulse width" is also added, plus the switch allows for more complex wave form output AC voltage signal (SW1 when closed). Is a small power transformer  T1 230 @ 100 years or 150 years, 12 volts horse. It must reverse connection, a secondary winding 12 v collector of Q3 and negative ground, and the primary winding 230 v, P3, and the output electrode. Circuits have been thoroughly tested, and it works well when 3 v - provides 9 v ranges. Running at 3 v 12 v 1.2 va supply a transformer will not be more dangerous than this circuit has been published. Note, however, use the 9 v battery supply which can output 120 v signal and can be very dangerous. Small metal plate electrode can be obtained an output connected to the circuit by a usual wires and is adhered to the skin. In some cases, a small amount of water moisture prove useful.
