The proposed pacemaker good to use in travel, business trips. It is easy to manufacture and gives stable settings if the problem persists. The use of any low-power low-frequency transistors, gives an opportunity to make his novice Amateur radio. Transistors apply any: GT, N... Using silicon transistors, it is necessary to change the polarity of the electrolyte and connecting the batteries. Led - any glow with the appropriate polarity switch. I have ALB.
The design of the device to perform better with one probe, and the second to use the metal housing of stimulator. The body was taken from the safety razor, metal. To a plastic housing glued metal strip. If you use the battery type "crown", it is necessary to increase twice the capacitance.
The switch SA1 changes the polarity electrodes, SA2 - toggles the nature of the work SEARCH WORK. In the "SEARCH" search active points. When the point - the led turns on. With a steady burning LEDs switch SA2 is placed in the "WORK" and made impact on the point. Current exposure is regulated by a variable resistor R5.
