Safety Lifters are not Toys...
Introduction What a "Lifter" is and how
it works
Prototype Lifter
Building the lifter....
A Lifter is an extremely
dangerous High-Voltage electrostatic propulsion device. It
IS VERY DANGEROUS!
Firstly, make sure that no one can
come in contact with it - mainly onlookers, and
yourself. Keeping large distances between the potential victims from any possible contact
with the high voltage is really the only foolproof way of protecting
against electrocution. People not familiar with high voltage can be
very naive. Always keep a safe distance from
your lifter.
Using a average monitor as a power supply deals with
very
high voltages, (generally 25,000-30,000 Volts). 1kV can jump about
an 1.1mm air gap.
This distance occasionally varies unpredictably with humidity. Don't forget that
a monitor circuit contains many capacitors which can store a high voltage
charge for weeks, even months. This makes it extremely dangerous! Always
remember to discharge all capacitors with a proper discharge probe
before making adjustments. (See Capacitor discharge tutorial)
Prevention is better than a cure!!!
Be safe!
See
http://jnaudin.free.fr/lifters/theories.htm for an in-depth
explanation of how lifters work.
Color Computer monitors make the
perfect "Lifter" power supply. It is easy to access and old
monitor, It is portable and runs off 120 Volts. Always
remember that monitor are filled with capacitors that can hold a
charge for weeks. Always remember to wear very heavy duty
rubber gloves. This does not make you immune to HV shocks
though. Prevention is the best cure for a shock.
Try to not touch any off the internal working of the monitor besides
the ones specified in the tutorial.
Now lets continue....Lets make a
power supply.
! IMPORTANT ! The
picture tube is vacuum sealed and can implode very easily sending
shards of glass everywhere. Always work with the monitor
screen on something soft like a towel to prevent damage.
Step 1: If the monitor is
plugged in, UNPLUG it! Then let the monitor sit for 1-2 hours
to let HV discharge. Now wearing your heavy duty electricians
gloves, remove the screws holding the outer case in place. Then
remove the case and set it aside.
Step 2: Now that you can see the
internal working of the monitor, note the silver ground wires that
surround the picture tube, mark this as the ground.
Step 3: With the monitor still
UNPLUGGED carefully lift up the side of the rubber "suction
cup resembling" plug on the side of the picture tube. Mark the high
voltage wire as "+"
Now that we have a Power supply,
we can continue to build the lifter.
Things You will
Need
Step 1: Measure and cut out 6 sticks
of balsa wood, 200mm Long and 2mm Wide. Then do the same for 3
sticks, 75 mm long and 2mm wide.
Step 2: Glue three of the 6 200mm sticks in a
triangle (see below)
Step 3: Next take the 3, 75 mm sticks and glue
one upright at each corner (see the above picture for an example of
the first one)
Step 4: Take the remaining 3,
200 mm sticks and glue them 30 mm up from the bottom one (one
between each two sticks)
Step 5: Cut 3 sheets of
aluminum foil. 210 X 45 mm.
Step 6: Glue one of these
to each side.
Step 7: Now your lifter
should look like this (see below)
Congratulations, Your Lifter is now ready for testing...
--------WARNING : HIGH
VOLTAGE--------DANGER--------
-
MAKE SURE MONITOR IS TURNED OFF
-
You will need to support both wires ate least
10 inches form the testing surface
-
Your supports must be not conductive, such as
glass or PVC.
-
Connect the top corona wire to the positive
connection on the picture tube, and connect the foil wire to the
ground wire or the picture tube.
-
Tether the lifter down with fishing line by attaching an equal
line to each corner of the lifter. This determines the height
that the lifter will go and keep the "+" and "-" from touching
-
THESE WIRES MUST NEVER TOUCH
IMPORTANT STEP
-
Find a power bar with an on/off switch.
-
With the monitor unplugged turn it on.
-
Now with the power bar OFF plug it in.
-
Attach the Monitor to the power bar.
-
When you are ready, turn on the power bar
from a safe distance.
WHAT SHOULD HAPPEN
-
After about three seconds you should hear a
hissing noise and possible sparks between the corona wire and the
foil.
-
Then your lifter should immediately lift from
the ground. Due to static cling it may not rise so try gently
blowing on it.
-
After 10 seconds if it does not lift turn it
off. !Consult Below!
If you lifter does not function Consult -
