FIRE HAZARD
Due to high power dissipations of the various semiconductors devices
attached to the heatsink, the heatsink may become extremely hot,
especially during periods of continuous operation. Please ensure the
heatsink is not installed on or near any flammable material and that a
cooling fan is ALWAYS used during operation.
SAFETY GUIDELINES FOR LINE POWERED EQUIPMENT
The electronic kit you purchased utilizes line voltages (115VAC) and also contains
circuitry that produces output voltages in excess of 400VDC. Normally, consumer
electronics equipment are safely enclosed to prevent accidental contact. However, the kit
you have purchased does not come with an enclosure, and must be handled and operated
with this in mind. Voltages exceeding 35V pose a safety hazard and depending on
overall conditions and your general state of health, voltage and current levels have the
ability to serious harm or even kill.
The following guidelines are to protect you from potentially lethal electrical shock
hazards as well as the equipment from accidental damage.
It is also important to note that the danger isn’t limited to only your body providing a
conductive path, namely your heart. Any involuntary muscle contractions caused by an
electrical shock, while perhaps harmless in themselves, may cause the person to be
injured by falling, hitting a body part on something sharp, etc….
The purpose of these set of guidelines is not to frighten you, but rather make you aware
of the appropriate precautions needed to safely build and operate this electronics kit.
Perhaps, the number one rule – Don’t work alone! If something does happen,
it is extremely important to have someone nearby to render assistance or to
call for help.
When working on energized equipment (namely those that are line powered),
always keep one hand in your pocket. This ensures there is not a complete

electrical path through your heart providing you accidentally make contact
with live voltage.
Wear footwear with non-conductive (rubber) soles. Do NOT work on line
powered or high voltage equipment in barefeet.
Always wear eye protection. Power semiconductor devices, and capacitors do
have the potential to explode unexpectedly and project sharp fragments across
the room.
Always work in a clean, open area. Avoid working in cluttered spaces,
especially if there are grounded objects nearby that could complete a circuit
path in the event you make accidental contact with live voltage.
Avoid wearing any kind of jewelry or other articles that could accidentally
contact circuitry.
Never operate your PC boards on top of conductive tables, or other conductive
objects. PC boards should ALWAYS be supported by the provided stand-offs
or placed on top of a non-conductive tabletop or other material.
ALWAYS allow proper time for any large electrolytic or other high voltage
capacitors to discharge after removing power prior to working or touching any
circuit. ALWAYS use a multimeter to measure the voltage across large
capacitors after power is disconnect to ensure the voltage has properly bled
off.
Use an isolation transformer if there is any chance of contacting line powered
circuitry. A Variac is NOT an isolation transformer!
Finally, if your kit involves a Tesla Coil – NEVER touch or attempt to draw
an arc with an object from the output of a Tesla Coil. The output of a Tesla
Coil poses not only an electrical hazard, but also a burn hazard. The output
from even the smallest solid state Tesla Coil can cause serious burns. Always
operate the Tesla Coil at a safe distance.
SAFETY GUIDELINES - SEMICONDUCTOR POWER DEVICES
Always wear eye protection. Power semiconductor devices, and capacitors do
have the potential to explode unexpectedly and project sharp fragments across
the room.
Power semiconductors may be extremely hot. NEVER touch any
semiconductors during operation or after use. Always allow proper time for
components to cool down prior to handling them.

SAFETY GUIDELINES – HIGH TEMPERATURE COMPONENTS
Power semiconductors may be extremely hot. NEVER touch any
semiconductors during operation or after use. Always allow proper time for
components to cool down prior to handling them.
The extruded aluminum heatsink will be extremely hot during and after use
until it cools down to ambient temperature. NEVER place the heatsink on any
material that is flammable such as wood, plastic, or paper. It is preferable to
place the extruded aluminum heatsink onto a metal plate.
NEVER operate the device without the use of a cooling fan. If you are using
an extruded aluminum heatsink, be sure to blow fan parallel to the cooling fins
of the heatsink to maximize the cooling effects of the fan. Always allow the
cooling fan to continue running, even after power is removed, until the
heatsink and board components are properly “cooled” down.
SAFETY GUIDELINES – ELECTROMAGNETIC FIELD OUTPUT
DO NOT USE THIS KIT if you have an implanted biomedical device such as a
pacemaker!
Electromagnetic fields are produced when the Tesla coil is operating. Ensure
that you and others are always at least five feet away from the devices during
operation (small kits), and farther away with some of the larger kits such as
the miniBrute Tesla Coil kit.
Avoid contact with metallic objects. This is mostly important for the smaller
CW based Tesla coils such as the SSTC 1.0 or Class-E Audio Modulated
Tesla Coil. What happens is that the electromagnetic fields cause charge to
build up on your person and any contact with something metallic will initiate
a potential RF burn to occur. The burns are on the magnitude of an
electrostatic shock – they are rarely harmful, but they can surprise you and
give you a small instant of localized pain – again similar in receiving a
electrostatic shock. Maintaining at least five feet away from the Tesla coil
will prevent his from occurring.
DO NOT use this kit if you have an implanted biomedical device.

Introduction to the Wireless Energy Demonstration Kit
Thank you for purchasing the Wireless Energy Demonstration Kit. This kit is perfect to
demonstrate the principle of wireless energy transfer and is designed to be used in
conjunction with our Class-E Audio Modulated Tesla Coil kits.
Notice to Beginners: If you are a first time kit builder, you may find this instruction
manual easier to understand than expected. Each component in this kit has an individual
check box, while a detailed description of each component is provided as well. If you
follow each step in the instruction manual in order, and practice good soldering and kit
building skills, the kit is next to fail-safe.
Please read this manual in its entirety before building, testing, or operating your kit!
Circuit Description
The Wireless Energy Demonstration Kit features a tuned Tesla Resonator and a ultra high
speed rectification circuit which converts the 4MHz energy from the Class-E Audio
Modulator into voltage and current which is used to illuminate twelve (12) ultra-bright
white LEDs. Firstly, a Tesla Resonator consisting of primary coil, L101 and secondary
coil, L102, which is tuned precisely at 4MHz, is brought into close proximity (within 3
feet) of the Tesla Resonator from the Class-E Audio Modulator Kit. The electromagnetic
field radiated by the Class-E Audio Modulator is then coupled into this second Tesla
Resonator where it is rectified by ultra high speed schottky diodes, CR1, CR2, CR3, and
CR4, and then filtered by capacitor, C1. The voltage developed across C1 is then used to
provide power to two strings of six (6) ultra-bright white LEDs. R1 and R2 serve as
current limiting resistors for each LED string and VR1 is a voltage suppressor to protect
the schottky diodes, CR1, CR2, CR3, and CR4, from over-voltage.

Kit Building Tips
A good soldering technique is key! Let your soldering iron tip gently heat both the wires
and pads simultaneously. Apply solder to the wire and the pad when the pad is hot
enough to melt the solder. The finished joint should appear like a small shiny drop of
water on paper, somewhat soaked in. If the pads have not heated up sufficiently, melted
solder (heated only by the soldering iron itself) will form a cold solder joint and will not
conduct properly. These cold joints appear as dull beads of solder, and can be easily
fixed by applying additional heat to the pad and wire. All components, unless otherwise
noted, should be mounted on the top side of the board. This is the side with the
silkscreen printing.
When installing components, the component is placed flat to the board and the leads are
bent on the backside of the board to prevent the part from falling out before soldering.
The part is then soldered securely to the board, and the remaining lead length is clipped
off. It is also extremely important to place the components as close to the board as
possible. This is necessary for proper operation over the wide frequency range of the
various kits we provide. Also be sure that component lead lengths are always as short as
possible. This will avoid adding any stray capacitances or inductances that can be
detrimental to circuit operation.
An alternative approach (which is actually the one I use) is to install the component into
the board and then apply a piece of masking tape on the topside to the hold the
component in place temporarily. The leads on the backside of the board are then trimmed
leaving about 0.10” lead protruding through the backside of the board, and then soldered
from the backside. You can then remove the masking tape, and finally apply a small
amount of solder on the top to complete the joint on both sides. This is shown in the
figure below.
