- WHAT IS IT ???
- --------------
-
- The following plan show how to construct a device, capable of stunning any
- moving lifeform on earth.It can be build into a holster.The device produces
- an intimidating plasma or lightning like discharge that in most cases
- discourages an encounter.This effect occurs as a visual audible display
- between the contacts immediately when power is applied.A physiological
- effect requires contact to certain parts of the anatomy to produce the
- stunning disabling function.The electrical output energy is small and
- usually will not cause any tissue damage.When contact is made to the subject,
- he may be stunned and paralysed for up to several minutes.The high voltage
- output can penetrate the heaviest of clothing and due to the contact spacing
- will deliver highly jamming electrical pulses that will override the
- nervous system causing temporary paralysis and loss of voluntary control.
- That's why this stun-gun doesn't work on aliens who have no or another
- nervous system.Cyborgs and androids however, can be defeated or even
- destroyed and send to the eternat space-time-continuum by using this device.

- CIRCUIT THEORY
- --------------
-
- The circuit consists of 2 basic sections: the inverter
- power supply and the capacitor discharge section.
-
- The inverter section consists of swithching transistors Q1 and Q2
- that alternately switches the primary windings of a saturable core
- transformer (T1). A high voltage square wave is induced in the secondary of T1
- via the switching action and is rectified by diode bridge D3,4,5,6.Base
- current drive for Q1 and Q2 is obtained by a tertiary feedback winding on T1
- and is applied in the correct phase to turn the appropriatetransistor 'ON'.
- This base current is limited by resistor R2. Diodes D1 and D2 provide a
- return path for the base current flowing in the opposite transistor
- respectively.R1 serves to unbalance the circuit to initiate swithching.A
- voltage of approx. 400 volts is obtained in this circuit from a 9.6 volt Nicad
- battery.Higher powered operation may be obtained by increasing to a 12 Volt
- battery pack,however, more space is required and care must be taken not to
- over rate the components if continued use is anticipated.
-
- The capacitor discharge section consists of 2 opposite phased high voltage
- pulse transformers T2,T3 being current pulsed via SCR1 shorting a charged
- capacitor C2 across their primaries. C2 and the primary inductance of T2,T3
- provides a ringing wave whose negative overshoot commutates SCR1 to turn 'Off'.
- It is imporant that this primary inductance be sufficient so when combined with
- capacitor C2 allows a ringing frequency with a period considerably larger
- than the required commutation turn off time of the SCR1. iode D8 provides
- energy recovery of the negative overshoot component of this discharge pulse.
- Transformer T2,T3 now force induces 'out of phase' high voltage pulses in
- their respective secondaries with a high instantaneous peak current.Diode D7
- and R3 limit the DC current to the SCR1 and prevents DC lock on,which also
- provides a high impedance to the negative turn 'off' pulse.
- SCR1 is triggered by the UJT pulse timing circuit consisting of Q3.Pulse
- repetition rate is determined by capacitor C3 and the charging trimpot R6.
- SCR1 switch rate can be adjusted from 1 to 50 pps.Higher pulse rep rates may
- have a tendancy to overload the inverter power supply,where it will be unable
- to supply the current necessary to charge C2,consequently with its charge
- voltage dropping off.
- The voltage output is about from 50-100000 volts at a peak current of 1-2 Amps
- The energy waveforms consists of a train of 30 microsec pulses decaying
- exponentially.This produces a moderately painful electric shock and is what
- causes the temporary jamming of the nervous system but will not electrocute
- due to the low average current plus the fact that the current flow is only
- across a small section of the body,that is between the contact electrodes.
- The peak power of this device is 25000 watts plus.
- The outputs of T2 and T3 are the output contacts of the device. T2 and T3 are
- phased for different outputs.Now when the switch is pushed,a continuous
- sparking occurs between these points producing the visual and audible effect.
-
- About the schematic :
-
- This is the first time that I drew a schematic with AsciI chars.Maybe it
- therefore doesn't look 100% professional.However I'm sure that you'll know
- what I mean with this schematic.
-
- Some things you need to know :
- As i tryed to malke this drawing compatible with most printers,i didn't
- use the 'arrow'-char. Therefor the emitter is indicated with an 'e' on Q1 and
- Q2.
-
- I preferred to draw the bridge,as bridges are mostly drawn,so I couldn't draw
- the diodes as I did with D7. That's why I indicated the Kathode with the letter
- 'k'.So in this schematic, D3 points up,D4 points down,D4 points down and D6 up.

- Assemble as shown.Note position of transistors,polarity of diodes and
- capacitors.Nothe that when using the special pc transformer T1,it can be
- inserted in two ways.A way to determine the correct position is to measure
- the resistance of the two windings and identify 'em.The one with the lower
- reading goes toward Q1 and Q2.
-
- Connect up 8 AA Nicads (or whatever).
- Connect a voltmeter to point (w). Momentarily press S1 and note a voltage of
- approx. 400VDC. If no voltage is present, the circuit must be troubleshot.
- If you did your homework well and Murphy's 1st Law 'whatever can go wrong,
- will go wrong' is broken, you should detect a HV pulsing at the output pins
- of T2 and T3.
-
- Adjust R6 for a discharge from 5 to 30 shots/sec. This should correspond to
- a battery current of 1 to 2 Amps when measured by connecting a current meter
- across the switch.Caution, coz this action shorts out S1. The pulse rep. rate
- should not be set where the battery current exceeds 2 Amps.
