Children should not build or operate this kit. This kit is not intended for children! Assembly of this kit requires high-temperature soldering and the use of sharp edged components and cutting tools. Some included components may become hot, leak, or explode if used improperly. Images strongly recommends that you wear safety glasses when building or working with any electronic equipment. High voltage discharges and shocks can cause injury and/or death. Additionally high voltage electricity as generated by this assembled kit can cause damage to property. SI Images disclaims liability for damage or injury caused by the use of the Fly Back Generator Kit. By using this product, you agree not to hold Images liable for any injury or damage related to the use or to the performance of this product. This product is not designed for, and should not be used in, applications where the malfunction of the product could cause injury or damage. 2 High Voltage Safety The High voltage Generator produces 15 kV (15,000 volts). This is extremely high voltage and may be lethal. The current our high voltage power supply can deliver is approximately 600 uAmps (0.6 mA). A person's health has an impact on the amount of current that would be lethal to any particular person. So please follow the safety guideline provided and do not use if you have a health condition which makes you susceptible to shocks. An electrical shock can cause you to jump, move or fall and can thereby cause a secondary injury, unrelated to the electric shock itself. Take the following precautions and treat all high voltage power supplies with the respect they deserve. Follow these simple guidelines and rules. 1) Keep one hand in your pocket. Only use your other hand to work with the high voltage equipment. This reduces the probability of accidentally passing high voltage current across your heart from hand to hand. 2) Set up your work area away from possible grounds that you may accidentally contact. Keep your work area neat and clean to easily identify high voltage wires and grounds. 3) Be sure the floor is dry and wear preferably rubber-soled shoes. 4) Prove to yourself the high voltage power supply is off, by unplugging the device's electrical power cord. Don't trust power switches that could be hit or pressed and accidentally turned on. 5) Discharge all high voltage before working on the device. This means attaching a wire to the circuit ground and touching the high voltage output terminal with the grounded wire. This will dissipate any stored high voltage charge. 6) Do not work on high voltage apparatus when you are tired and not alert even if it means a delay. 7) Never charge a capacitor using the high voltage power supply. Even small high voltage capacitors can deliver lethal current! 8) Never leave the generator plugged in while unattended. 9) Do not use the generator if you have a heart condition, are pregnant, or have any condition or health issue that might render you susceptible to electrical shocks. 10) Keep your mobile phone, personal computer, tablet, or other personal devices at least ten (10) feet away from the generator as they may be permanently damaged. 3 11) You must furnish your own power source for this kit. Never use an incompatible or incorrect power source as it may result in the generator overheating or fire. 12) Use safety precautions when soldering and assembling the kit. 13) Do not use the kit except as assembled per the instructions contained herein. 14) Do not add, substitute or remove components to the kit assembly.

How it Works Look at the schematic on page 6. When power is applied to the circuit, the current through resistor R1 and feedback winding (14T) coming in to the base of the transistor and puts the transistor into conduction. This initiates current through the primary windings (16T) creating a magnetic field in the transformer and inducing a current and high voltage spike on the secondary windings (4,200T output) of the flyback transformer. At the same time the magnetic field reversed the polarity in the feedback coil (14T), turning off the transistor. With the transistor turned off the current is cut which causes the magnetic field in the core to collapses, keeping the current in (14T)feedback winding reversed. After magnetic field in the transformer dissipates, the transistor is again pushed into conduction through the R1 resistor and circuit operation repeats. High voltage is generated when the oscillation is adjusted to a resonance frequency of the transformer which in this circuit is approximately 22KHz. 5 6 Construction Begin construction by attaching the TIP35C transistor to the aluminum heat sink, see figure 1, using the 6-32 machine screw, nut and #6 split lock washer. Figure 1 Next, solder the transistor to the pcb board and solder the mounting pins of the heat sink to the pcb, see figure 2. Figure 2 The fly back transformer is soldered to the PC board. The ring terminal on the HV wire output of the fly back transformer. See figure 3 Figure 3 7 Locate P1 and P2 on the PCB. Insert a small piece of wire into the top 2 holes at each position and solder into place (see figure 4). Figure 4 Next mount and solder the following components; C1A and C1B, 1000 uf 50V capacitors, SW1, on-off toggle switch, D8-D11 (diodes 1N5402/01), D2,D3 and D4 (FR102) D1 (FR204) making sure the band on the diodes are oriented properly according to the silk screen outline for the diodes, resistor R1, 7.5K ohm and power resistor R2 (470 ohms). Finish up by mounting C2 (2.2 uF 100V) and C3 (2.2 uF 250V) capacitor. The C3 leads are bent as shown in figure 5 and mounted as shown in figure 6. C3 does not have a polarity and may be mounted with either lead in the + pcb hole. Figure 5 Figure 6 Finish the circuit be mounting and soldering the green two terminal block. Next mount the four clear plastic feet on the bottom of the pcb. Usage: To power the high voltage generator you need to attach a power supply to the two terminal block. We recommend a 12 VAC 500 mA or 12 VDC 500 mA power supply. Attach power supply wires, any polarity to the terminal blocks and secure the wires with the top screws. Turn on the high voltage generator using the on-off switch. Pictures to the right are shown with optional discharge ball (not included). 8 Lighting a small Geissler tube.

An ion is an atom or molecule that is no longer electrically neutral, it has become unbalanced electrically. The way it becomes unbalance is by the loss or gain of a positive or negative charge. When this happens the atom (or molecule) turns it into an ion that is either positively or negatively charged. So an oxygen atom (or molecule) that acquires an free electron becomes a negatively charged ion. If however the oxygen atom loses an electron it becomes a positively charged ion. Generating Ions There are a few ways ions are generated; radioactivity, high temperatures, UV light or high voltages. We will focus on how high voltage can generate ions. When dealing with high voltages, the shape of a conductor has an impact. For instance a sphere will hold a high voltage charge. While a sharp point bleeds ions into the atmosphere. This property is used to generate air ions in commercial ion and ozone generators. To generate ions using the Plasma generator you need to connect a sharp point to the high voltage ring terminal. Be careful, a spark from the plasma generator can jump further from a sharp point that a sphere. 10 More fun things to try: William Betty has a number of ion experiments to perform on his website: http://amasci.com/freenrg/iontest.html More experiments: Visit http://www.imagesco.com 11 Parts List 1 Transistor TIP35C (Q1) 1 PC mount Toggle Switch SW1 1 2.2 uf 100V capacitor (C2) 1 2.2 uf 250 V capacitor (C3) 2 1000 uf capacitors ( C1A and C1B) 1 FR204 Diode (D1) 3 FR102 Diode) (D2, D3, and D4) 4 1N5401/02 diodes (D8-D11) 1 7.5K ohm resistor (R1) 1 470 ohm power resistor (R2) 1 Two position terminal block 1 Flyback transformer (with ring terminal) 1 Printed Circuit Board Hardware: 4 Plastic stick-on feet 1 6-32 x 7/8" machine screw 1 6-32 x 1/4" machine screw 2 6-32 nut 1 Aluminum heatsink Option Power Supply (not included with kit) 12 VDC 500 mA wall transformer power supply with wires for connecting to PC Board PN# ACA-12VDC-MWW $9.95 12 VDC 500 mA wall transformer power supply with 2.5 mm connector.

The first band is the one nearest the end of the resistor. Start reading from this band. The first band represents the first significant number, the second band, the second significant number and the third band is the multiplier. If the third band is gold or silver this indicates a multiplier value of .1 or .01 respectively.
