This variable
HV power supply is made with a TV Fly Back Transformer, giving
a pulsed High Voltage (about 15 to 20 Khz).
The circuit is based on the one give
by Jean Louis Naudin at:
http://jlnlabs.imars.com/lifters/labhvps/indexfr.htm.
It has however some improvements : type of transistor and potentiometer,
separated 12 v supply for the oscillating circuit and the numerical voltmeter
(100 v step), heaters, a 1Gohm resistance. The luminous display/voltmeter
is very useful during the study of corona effect in the dark. Design and
ergonomics have bee studied specially for the experiments in electrokinetics.
Transdimensional
Technologies (no more website) was at the origin of
the first Lifter demonstrating the Bieffeld-Brown effect
in June 2001 : a system made of two electrodes charged at
high voltage moves in the direction of the energy gradient.
The Lifter from Transdimensional Technologies was
based on the patent 2.949.550 from Thomas Townsend Brown
(see here).
Jean Louis Naudin (France) made a successful replication
in October 2001 and contributed largely to spread this knowledge
among the nations. Various tests with ordinary High Voltage
machines (Whimshurst, van de Graaf) gave only weak results
with suspended condensers, because of the too low intensity
of the currents (microamps). But with the FBT power supplies,
the effect has been fully revealed. The push from the electrode
system is enough strong to lift itself. Various tests show
that a big lifter (250g) was able to lift a 60g payload,
and the record was 100g in July 2006 (Saviour at http://www.blazelabs.com/).
Now the proportional power to make move upward a lifter is
still higher than the one to lift an helicopter. The system
is not yet profitable energetically speaking, until we understand
perhaps more what happens and how to increase the effect.
The
Fohat-30 has been made to experiment with the Lifters but may
be useful for other experiments involving more potent high
voltage than what we can obtain with the ordinary electrostatic
machines.
Warning !
Building
such a HV supply is your own responsibility. It
is only designed for people who are skilled in electronics.
High Voltage experiments
are dangerous, and may hurt you, or even cause death to people
using pacemakers, or having heart disease or any other heart
weakness. If you know only few things about high voltage or
electricity, and electronics, please ask for the help of a
more skilled person. Be extremely careful. Though the lifters
seems to be a very funny game, they are not! Consider it as
real scientific experiments, and be as serious as you can to
protect yourself and others in your house or "laboratory".
Take care particularly of the children who could try to replicate
your experiments when you're not at home. If you build a HV
power supply, the risk of any results is just yours. I take
no responsibility of anything that might happen.
We
sell this pack to make experimentation easier, and to avoid
you the tiresome research of the various components. You
will save time and posses a professional looking power supply.
The pack includes the printed circuit, the electronic components
to solder, the case and the front panel already drawn and
cut, a High Voltage cable (1m25), a 0v cable with a crocodile
clip, a discharge wand, a super-resistance (1Gohm), a numerical
luminous voltmeter, assembly instruction for the supply and
a basic Lifter.
As the plans of this device were given
freely on the internet, its price is very low regarding the ones from professional
providers.
The
profit is designed to support the
Research Center. It is a fixed rate corresponding
to the needed time to prepare the various parts of the pack: printed circuit,
front panel, super-resistance,
special cables, discharge wand, etc.
