The resonator technology is only one component
in a much larger system I am researching about, and the following descriptions
are only a very tiny, but hopefully useful fraction of those resonator-
related things I have experience with.
In context of modern psychedelics
a resonator is an inflatable membrane structure with the main purpose of
conducting, intensifying and modifying signals of bodily vibrations.
The main type of resonators used in my yoga is made
from rubber gloves those get closed with a nylon cable tie (e.g. by using
2 pliers). Gloves with a skin- sympathetic coating can be turned inside-
out before doing so to make the resonator surface feel different. The
end of the mounted cable tie should be cut off with small scissors or wire
cutter in a way that no sharp edge remains (that otherwise could perforate
the membrane or injure you).
Important is to free the resonator from potentially
toxic chemical remains by washing them now carefully, but thoroughly with
lukewarm water from outside before using them the first time. Sorts with
a chemical smell or smeary remains of chemical protective fluids should
be washed in detergent water for safety reasons. Important is not
to soak latex rubber in water for long time, because long enduring humidity
and especially soap water is not good for latex. (To remove possibly harmful
dusts from inside, rubber gloves can also be washed from both sides before
processing them, but to avoid damage of the material it is important to
dry them completely before mounting the clip, which needs a bit more effort.)
The resulting resonators can be inflated afterwards
by cutting a small, round hole into the tip of one of its fingers, which
can be closed afterwards with a knot to keep the air inside. (Don't knot
too tight, to make it possible to let the air out again later, and
avoid to cut the hole in a slit like or jagged way, because this would
tear out very easily.)
Another possibility to make such resonators inflatable
without knotting a finger of it is to include a small plastic pipe as an
inlet into the cable tie clip. Important is here not to roll, but to fanfold
the glove's opening around the pipe before closing the clip, because otherwise
its membrane will tangle during inflation - resulting in a one- way- valve-
like effect. As inlet pipe an empty pen ink cartridge with removed bottom
is well suited. Important is to mount it with the bottom- hole outside,
because though for closing it another empty ink cartridge (with bottom)
can be plugged into the opening of the 1st one. All ink cartridges should
be washed out under a water tap before installation to remove the ink remains
as good as possible, because ink can be toxic and may cause allergies.
Water should not remain inside the cartridges, because latex suffers from
long exposure to humidity. To get it out of cartridges with intact bottom
again, simply shake them like an old style fever thermometer. (Squeezing
the cartridges works also, but easily cracks the plastic and though makes
The PE of ink cartridges is a bit fragile and
tends to crack when flexed too often or bent or when the plug is jammed
in or cable tie is fastened with too much force. Thus to improve the reliability
of all frequently used resonators, I recommend to make their inlet pipes
from a piece of PU hose instead (ø6/8mm polyurethane, available
e.g. as hose for PC water cooling or fish tank air supply). This material
is rigid enough not to be crushed by the cable tie, but flexible enough
to avoid cracking, and unlike plasticized PVC it does not attack latex
over time. Also here ink cartridges work well as a plug.
If the inlet pipe diameter is a bit too small
to fit tightly into the opening of a standard airbed pump hose nozzle,
a few layers of adhesive film can make it fit. However some adhesive
film or -tape glues seem to decompose latex over time, so I do not recommend
this anymore. Adhesive films with perfectly transparent ("crystal clear")
glue seem to be less aggressive than those with yellowish or brownish glue;
the latter generally tend to stay stickier and leave sticky residues on
surfaces when peeled off later. But adhesive film also makes trouble because
it tends to loosen in the worst moment, which can disturb meditation a
lot. To make the nozzle fit perfectly without it, make an adapter from
a piece of rubber hose. Generally it is a good idea to make a set of adapters
with several diameters (e.g. from short pieces of rubber or silicone tubing,
cable insulation etc.) to snugly fit on all kinds of inlet pipes.
When a resonator slowly looses air, there is most likely a problem
with the inlet. Inlet pipes e.g. tend to easily get leaky as well by a
too loose as a too tight cable tie. While a too loose one simply doesn't
seal well enough or loosens further by use, a too tight one crushes or
deforms the plastic pipe or even pinches a small hole into the latex membrane
and though causes leakiness. Crushing of the pipe can be prevented by inserting
a round, solid stick (e.g. screw driver) of well fitting diameter into
it before fastening the cable tie. How well this construction seals also
depends much on the thickness and structure of the glove's material. (Thick,
hard or embossed rims tend to seal worse.) To improve the sealing, it can
help to roll a few layers of a strip of thin latex foil (e.g. cut out of
a defective glove) around that section of the pipe where the glove rim
gets folded together before fastening the cable tie over it.
To remove a cable tie for repair, hook with a small screw driver or
similar into its eye and bend the small flap upwards. (To simply cut the
tie with scissors or knife is not recommended, because it would easily
perforate the resonator's membrane.)
To detect small holes in resonators, their air current can be felt
best with the eyeball by holding your eye close to its surface. Also dipping
the slightly inflated resonator under water to search for rising bubbles
may be performed, but remember that remaining humidity would be not good
There are also other special types of resonators;
some are secret, many are not reliable enough, and many are only of limited
use, but another very well functioning, quite big, kidney- shaped resonator
can be build from a thin latex swimcap by mounting an inlet pipe in a similar
way like described above. (More informations about resonator details
and additional resonator types can be found in the pictures
section of this site.)
Tip: For acute latex allergics
(also see here) silicone swimcap resonators (described
might be an alternative to benefit too from most of the following meditation
exercises. Unfortunately at least the sorts I tried seem to emit toxic
chemicals those vapours maladjust my nervous system badly and made me feel
To a newbie the effort of building resonators may appear strange, because
he may think that ordinary cheap toy balloons from any shop around could
serve the same purposes also. But as an experienced person you can trust
me that the material qualities of good resonators of this kind can be very
different from those of simple throwaway toy balloons and have sensually
nearly nothing common with them. It is really worth this work - when treated
with care, the lifetime of a good resonator can last very long. The
inlet pipe construction can also well be added to (e.g. large) toy balloons
to make them easily deflatable for re-usability.)
Laws of latex...
For safe work with elastomer
(rubber) resonators it is important to know that elastomers follow their
own physical laws those need to be urgently regarded to avoid to destroy
them. Important is especially to learn to distinguish in which range the
resonator's material is operated.
The sensitivity with that the membrane of a resonator
reacts on an increase of stress with an increase of strain is called the
"steepness" of the membrane (due to the steepness of the material curve
in the stress/ strain diagram).
The more the membrane gets stretched, the lower
gets its steepness (i.e. the tighter gets the material) for a short time.
The problem is that at higher operating ranges (i.e. higher given strain)
the molecule chains of an elastomer begin to drift slowly apart from each
other, causing the steepness to locally increase again (making the material
softer) there with the time. And increasing steepness causes the less stretched
areas (those steepness is still low) to draw the more stretched ones into
even higher ranges. And because not stress, but strain is the limiting
parameter, the membrane therefore gets endangered to get destroyed by this
instability as soon the system just gets driven into a too high range and
left alone without any additional load.
Finer definitions of the operating ranges can be
indicated using a dot. Though "range 2.1" describes that the material is
operated somewhere at the lower end of the linear range, while "range 3.5"
indicates that a resonator is driven quite high into the 3rd range and
though must be treated very carefully.
||(not in operation)
The membrane is not stretched at all.
||(the safe range)
The membrane is only stretched little. (ca. <
20% of max. possible strain)
Vibration transmission begins to get possible.
There is no danger of damage in this range.
||(the linear range)
The membrane is much stretched. (ca. 20% <
75% of max. possible)
Vibration transmission works well.
Only up to this range a resonator should be stressed
by body weight for a longer time.
The membrane is extremely stretched and gets
feelable tighter. (ca. > 75% of max. possible)
Vibration transmission is excellent, but strong
drift begins =>danger of destruction when operated this way for
a longer time.
The lower part of the 3rd range can be suitable
for a few special applications, but operating the material in the upper
3rd range without careful observation is not recommended, because the drift
can easily lead it to spontaneous destruction.
Fore surely determine whether the membrane of
a resonator is operated in the 2nd or 3rd range, simply touch the membrane
at its mostly stretched area with the spreaded fingers of your flat hand.
Then move your fingers horizontally together (unspread them) while still
touching it; if the surface easily follows this movement, than the membrane
is operated in the 2nd (or lower) range. But if you feel a noticeable resistance,
then it is already in the 3rd range.
Remember that an inflated structure like a resonator
forms a wholeness, though for its
safety it is not crucial how little stretched large other membrane areas
may be, but instead only whether or not there is any small area somewhere
on it which is endangered to get destroyed by operation in a too high range
or by a visible material fault or anything else.
The differences in the properties of resonators
made from different rubber glove sorts are enormous, though I can only
recommend here to try out many different ones for getting experience.
Don't use resonator sorts those emit a stingingly chemical smell that makes
you feel bad! Such antiprana is not only unpleasant, but unlike latex
itself or weak remains of ammonia, most chemical smells also easily prevent
success in meditation and can maladjust or even damage the nervous system.
(More about this later.) Chemical
smells can sometimes be removed from new rubber simply by letting it openly
lie around in a room for one or few days to let the odorous substances
Tip: Very plain and cheap no-name
latex rubber gloves tend to smell much better than expensive brand products,
because no-name ones are typically of much purer natural latex rubber,
while expensive ones rather include costly chemical surface coatings etc.
those emit chemical odours.
After releasing the stress from a stretched elastomer
that was operated in a high range and/ or for a long time, due to drift
phenomenons the material usually can not entirely contract to its original
size anymore; this phenomenon is called hysteresis.
E.g. the material of ordinary toy balloons has an extremely high hysteresis
(which gets obvious after deflating them). The hysteresis of good rubber
glove sorts in comparison to this is often by magnitudes lower. There are
short term and long term hysteresis phenomenons.
long enduring hysteresis can sometimes be decreased by carefully supplying
mild warmth and motion to the material (e.g. by gently massaging it with
warm hands); to gain best results this should be performed as soon
For many applications resonators work nicely already in the 1st operating
range, which makes them last almost forever when treated correctly. As
sufficiently large resonators for this inflatable latex cushions work great;
also shoulder long latex gloves and stockings make nice resonators. Such
accessories are available as rubberist
supply - watch out that the prices vary extremely among manufacturers and
shops - many are expensive, but some reasonably priced sources and tips
are on the links page. Also giant balloons of latex
make great long lasting resonators for 1st range operation. Especially
the really big ones (fully inflated size 2m or larger) and large figure
balloons are interesting, but always check their uninflated size first,
because some types can be disappointingly small. Also here the prices vary,
but eBay tends to be a good source for them.
It is important to understand that latex gets
easily damaged when treated wrongly. The material must not get in contact
with any oil- or fat- like substances, and it also reacts sensitive to
heat, UV radiation (direct sunlight) and to air pollution like e.g. ozone.
(Therefore put that smelly laser printer better elsewhere...) The material
reacts especially sensitive while it is stretched, and also a small amount
of drift is always present already in the 2nd operating range, though don't
keep resonators inflated higher than in the 1st range for a long time without
having a reason to do so. Some sorts of natural latex rubber even already
react on simple contact with warm water with getting discoloured brownish
(especially while driven in 2nd or 3rd range), though the material must
be treated very carefully. Long exposure to humidity in general is not
very good for natural latex objects, though it should be avoided to inflate
them by mouth to prevent that humidity gets enclosed in their air chambers
for long time.
Important: When a latex resonator
got in contact with body fluids (e.g. tear drops, sweat stains), they should
be washed off very soon (by hand under a water tap) to prevent damage.
Oils and acids and possibly also germs and enzymes in body fluids can destroy
it. Whenever latex gets in contact with anything oily or fatty (essential
oils, foods etc.), it must be washed off immediately with detergent
water; otherwise it will dissolve. The washing water must not be hotter
than hand warm, the soap must be washed off again and after wash the latex
must be quickly dried completely (e.g. using a towel). Soaps for cleaning
latex must be mild, free of "re-moisturizing" (i.e. re-fatting) skin care
substances and not be perfumed, because fats and many fragrances decompose
latex, and fragrance smells last extremely long in the material and though
easily disturb meditation. Best is ordinary cheap
dishwashing detergent; soap bars and most body soaps harm latex.
Latex must not be washed in strongly stretched state and never during contraction
from it, because there it would get much stronger attacked and damaged
by contact with water and especially soap. Humidity must not get into air
chambers (where it can't get out again), though always close the inlet
of resonators before washing.
When not in use, resonators should be stored best uninflated in closed
plastic bags at a dry, not too warm place and away from UV light. Light
with UV very easily decolours certain dyed latex sorts and also damages
the material. Closed plastic bags especially serve the purpose of protecting
the resonators from continuous contact with ozone from circulating air,
which otherwise attacks the latex (and though e.g. would make it smell
soon). Also avoid to store nice smelling latex objects together with bad
smelling things (including such rubber sorts) because latex easily picks
up bad smells. Do not store latex together with soft PVC; plasticizers
in PVC decompose it. Also contact with metals containing copper or silver
(especially combined with humidity) damages latex. Never store moist
latex or anything moist together with it in air tight containers
like plastic bags - much like paper, latex will otherwise soon rot
and decompose into a brown crumbly mess when exposed to humidity for longer.
Hints like these may appear exaggerated to newbies, but it is important
to understand that latex rubber is a chemically very vulnerable material,
which in many ways can be rather compared with a living organism than with
those durable solid materials most nowadays technical goods are commonly
The membrane of a new elastomer resonator stays
quite inelastic (steepness stays low) until it has been stretched for the
1st time. Due to geometrical force distribution reasons it is not possible
to equally stretch the membrane of a (non- round) resonator by simply inflating
it freely. Though to avoid damaging it by those instability effects explained
above, the membrane can be stretched more equally by carefully inflating
it while using the own body weight in a skilled way to squeeze the resonator
into a shape where no area of its membrane will reach the 3rd range much
sooner than the other ones. The process of doing so is called "elastAyama".
Important is especially in elastAyama never to
use raw force against the material. Latex always needs to be treated with
respect and awareness - otherwise it will get soon destroyed.
If you intend to expand a precious latex inflatable
to modify its shape or steepness permanently, better drive it repeatedly
only into the 2nd range and deflate it again, which is much safer than
3rd range operation. Stretching too far can even make latex decompose;
for the same reason also strictly avoid contact with sweat (or any body
fluids) during elastAyama if you want to make the inflatable last long.
For inflating resonators in a careful and sensually
pleasant way, a small, dome- like shaped airbed pump/ bellows consisting
of soft- plastic (without a hard top and bottom plate) can be very recommended,
because such a pump can not only be operated by foot, but also by hand,
by knee and many other ways comfortably, which is e.g. important for performing
elastAyama experiments. For larger inflatables a large single stroke piston
pump is recommended (like used for inflatable boats). Modern dual action
pumps (those pump during push and pull of the handle) are less suitable,
because they need more force to pull the handle up again and so their stand
needs to be held down by foot during use.
yogic use of resonators
As the term suggests, the main purpose of resonators
is to intensify and modify vibrations - especially the vibrations of the
human body in the yoga.
It would be far beyond the scope of this text
to introduce in the basics of yoga, and I also can not detailedly describe
all the various exercises featuring resonators here, though I only will
give a tiny overview of which sorts of things can be done.
When applied correctly, the feelings of resonator
based psychedelics can be absolutely fantastic.
Important is that the methodologies I use are
very effective and though have strong consequences, therefore they must
be used carefully to avoid harming yourself/ feeling worse afterwards.
Generally in yoga any hectical body movements should be avoided and no
yoga exercise should be performed by force for a longer time/ with a higher
intensity than it stays feeling pleasant.
Remember - the dynamics range of our nervous system
is limited, therefore too strong signals will maladjust it. Though when
any yogic exercise feels unpleasant, it is much more likely that this happened
due to too high intensity than to too low one. Generally never do anything
(no matter what) which causes a complete, total bodily exhaustion, because
this state is always harmful and will maladjust and easily damage the nervous
system. Though always recognize your body as your friend - not as your
body postures with resonator)
A typical way of applying resonators is e.g.
to sit in the lotus seat (i.e. with crossed legs) on the floor and gently
press the resonator with in certain ways crossed arms and/ or clasped hands
against the chest and/ or the lap while concentrating the awareness at
ones pulse, breathing etc. The vibrations of these body signals get intensified
and conducted to other body areas by the resonator's membrane, which synchronizes
various brain areas* with each other by the synchronous perception.
(* Synchronizing various brain
areas with each other to a common, low frequency (alpha waves, theta waves,
delta waves) is in general the most important, central main principle of
meditation; it enables the brain (beside others) to process previously
blocked information jams and though to work more efficiently again. The
application of special body postures as a key element to create altered
states of mind by intensifying/ guiding bodily vibrations, controlling
blood flow etc. is already known since the earliest shamen cultures and
it lead finally to the meditation assanas of the yoga. By the use of resonators
in assanas, many of these positive effects now got achievable much easier
to people from today than to the generations before us.)
The effect of such assanas can be intensified
by carefully bending your trunk forward, though making a fraction of the
body weight rest on the resonator. (Very important is here not to cover
a too large area of the membrane with your body, because otherwise the
vibration signals will get damped too much for working properly.) For such
meditation assanas in the lotus seat also latex swimcap resonators are
well suited. Placing such a quite big resonator horizontally on ones lap
and resting the crossed arms upon it creates a very good sync and can feel
a rubber glove resonator in a way that its glove fingers touch shiatsu
points in the face creates interesting sensual effects.
Another useful meditation assana (lanternBoato_assana)
is simply to lie flatly on the back on a hard ground and hold a resonator
with both hands at its sides gently against your chest/ abdomen and keep
the elbows resting left and right on the ground - concentrating the awareness
at the resonator's vibrations.
There is also an assana group with sitting on
a resonator (in the lotus seat), which leads to a completely decoupled
state (and also stimulates the muladhara chakra,
which eases to achieve enlightenment),
but the technical problem is that it is very difficult to get resonator
sorts strong enough to bear the body weight for a longer time.
In another class of assanas (the subtena_danurAssana
group) you can lie on the floor with your chest/ abdomen resting on a resonator.
Dependant on the steepness of the resonator's membrane (and the degree
of inflation) it is possible to make it bear a fraction or even the entire
weight of the body by carefully lifting the legs into the air in certain
positions (e.g. lotus seat), which has strong effects on breath and blood
flow and can feel very refreshing when done correctly.
Important for positive and pleasant effects of
especially this sort of assanas (but also others) is not to perform them
with a full stomach and to completely empty your bowels on toilet before
beginning them. For supplying energy to the body (despite keeping the stomach
empty) dextrose bars are very recommended. Also don't practise yoga in
a too warm room; the effect would be neither pleasant for your body nor
very good for the resonators (because it increases the drift in their material).
Important to know is that the membrane of a resonator
will never forget what you ever have done to it. Like your body the elastomer
will not tolerate repeated overload, and though it will get destroyed soon
when you disregard the laws of the latex.
of static electricity)
By rubbing a resonator against e.g. a hairy part
of the own body, the membrane can be charged electrically. By letting the
electric force fields influence the skin nervous system by holding the
resonator close to it, very strong manipulations of the body's signal processing
are possible. (E.g. the charged resonator can be moved slowly upward a
few cm distant from the front of the body, moving from the genital area
up to over the head for influencing all the the chakras.) The effect of
this can be very pleasant and energizing when done carefully.
The electrical activity of different resonator
sorts varies a lot. Sorts with a very smooth surface usually have a high
activity. The chargeability is also dependant from the actual air humidity.
is already part of the higher methodology - I only mention it here because
some people might otherwise re-discover it without me and carelessly make
nonsense with it. Electrical methodology is a very powerful tool and no
toy! It can seriously maladjust the nervous system when used with too high
intensity, though it should only be applied for maximum a few minutes.
If a kind of weak burning is felt on the skin, then it is already a symptom
of an overcharge of the nervous system, which must be recognized as an
alarm signal to immediately stop. Also be careful not to damage microelectronic
devices (e.g. mindmachine) by touching unprotected contacts of them while
being charged electrically.
resonator as a sound instrument)
Resonators intensify and modify vibrations, though
by carefully drumming with the fingers on the membrane of a resonator (in
a tabla- like way), a great variety of interesting sounds can be generated
those are useful for creating altered states of mind. (The perception of
sounds and vibrations is an important key element in the meditation systems
of yoga. Also remember the drumming of shamens... ResonaKampaña
can also be applied well in music therapy.)
This methodology is one of my favourite ones!
- I really love to work and play with quiet sounds in many subtle ways.
A secret is that most of the interesting sounds
in resonaKampaña normally can only be perceived in the near- field
of the resonator, because the complex, revolving wave forms cancel out
each other already in a distance of few centimeters. Though the resonator
needs to be held close to the ear to listen to them. (Don't worry, a resonator
will never explode at your ears without having a serious reason to do so;
though so long you won't operate it recklessly in the upper 3rd range and
keep pointed and sharp objects away from it, nothing harmful can happen.)
By holding the resonator in one hand in a way that it can vibrate freely
(e.g. on its glove fingers) and slowly changing the relative position of
the resonator to your ear and moving the drumming hand over its surface,
very interesting, morphing sounds can be generated, those can be only compared
with the ones of electronic synthesizers. (For recording them, a special
kind of in-ear microphone is needed.) Other sounds*
are creatable by gently rubbing on various areas of the membrane with your
of these sounds are a kind of dolphin- like. From brain research it is
well known that the perception of dolphin sounds (the sonar staccato etc.)
influences the autonomous nervous system and synchronizes the brain waves
in a way that can create altered states of mind with strongly harmonizing
(and seemingly even seriously healing) effects. Though creating such sounds
for psychedelics purposes should make a lot of sense.)
On singing at the membrane a resonator will responds
with vocoder- like reverberation sounds.
By squeezing the resonator partly against the
body while drumming on it with the fingers, the response will change to
more typical drum sounds those can be varied in many ways by placing your
other fingers at different locations on the membrane. Gently pressing
the membrane near the space between 2 glove fingers causes interesting
buzzing noises when it makes them loosely touch each other. Also
by knocking against the glove fingers, the membrane area near the clip
etc. many very different sounds can be produced (and felt in the entire
body for meditation).
The sonic characteristics of resonators made
from different rubber glove sorts etc. are extremely different (from dull
drum sounds up to nearly bell- like tones), and also the operating range
has an influence (usually the higher, the more spectral tones get audible),
though this is a very wide field for interesting experimentation.
This was only a very brief abstract about some of
all the nice things I have learned about, written down here with the hope
that they can enrich people's life in a positive way.
