Cylinder shock

OPERATION: The pulses are generated by a simple oscillator hartley with a single transistor, pulsations that are coupled to a processor that raises the inverted voltage of 1 or 2 small batteries. R1 and C1 are responsible for determining the frequency of oscillations, if you change any of these components or voltage, the frequency will be changed. The sensations are different with each frequency.
List of components:
capacitors :
C1: 160 µF. 10 V. (electrolytic)
Q1: 2N2222 (NTE 123A)
Resistors:
R1: 1.8K
Other:
S1: pushbutton
T1: Transformer with primary and secondary for 115 volts to 100 volts for 6 or 200mA.
B1: 1 or 2 batteries of 1.5 volts
1 plastic tube of 2 inches in diameter and 10 inches long.
Contacts: Strips of aluminum in the form of caps that fit the plastic tube font>
