What is a gyroscopic hand trainer Power Ball HG3238
Gyroscopic hand trainer Power Ball — latest invention for the development of arm muscles. As soon as you take the gyroscopic wrist Power Ball simulator in your hands, it immediately begins to provide you with serious resistance. The faster you spin the device, the more force you need to apply to keep it.
The gyroscopic wrist Power Ball simulator can be used by everyone: children, women, men and even the elderly. You are able to dose your load yourself, it is impossible to harm yourself with training!
How useful is this trainer?
This gyroscopic wrist Power Ball simulator is successfully used to develop hands by both athletes (tennis players, boxers, rock climbers, cyclists) and musicians (guitarists, pianists, saxophonists), as well as all those who want to pump up their forearms, increase arm strength and brush flexibility.
The hand trainer is very useful for musicians.
The gyroscopic carpal simulator can also be used for recovery after injuries, as it makes it possible to perfectly develop hands.
Also gyroscopic hand trainer allows you to get rid of pain in the hands, the so-called tunnel syndrome (occupational disease of those who spend a lot of time in front of the computer).
Features of training with a simulator
So how does the miracle hand gyro simulator Power Ball HG3238 work? Everything is very simple. In the middle of the simulator is a gyroscope, which you run with your finger, a cord.
As soon as the simulator is started, the gyroscope begins to work in the opposite direction, creating a strong pressure on the arm. The more the simulator spins, the more difficult it becomes to hold it. The sensations are simply unforgettable: the thirst to conquer a naughty ball, excitement make training a fun, inconspicuous and very useful game.
Train with gyro simulator hand Power Ball can be anywhere and anytime: in the subway or on the road, at school or in the office, at home or in gym! You don't need a lot of space to practice, and the POWERBALL itself fits into a pocket or handbag without any problems.
World famous hand trainer. Gyroscopic hand trainer - an apple-sized trainer. This simulator allows you to develop your hands, but not with the banal "eights" and "waves through the fingers crossed", but with additional physical activity: this baby with a total weight of up to 200 grams. able to resist with a force equivalent to a mass of up to 15 kg!
This is where consciousness begins to argue with the laws of physics: No, this is NOT science fiction. This is a fitness toy. Performing exercises with the simulator, you can improve the strength and tenacity of the fingers, train the strength of the hand, shoulder and forearm.
In the middle of it is a rotor that activates the gyroscope: the inside of the simulator rotates in different planes.
The operation of this simulator is based on the principle of a mechanical gyroscope.
If some force is applied to the gyroscope (in this case, rotation with a brush), then it will begin to rotate around some axis that does not coincide with the main axis of rotation of the inner rotor. At the same time, a certain centrifugal force arises, trying, as it were, to snatch it from your hands.
And you will have to resist this force by firmly holding the Powerball in your hand. The speed of rotation of the inner rotor is up to 15,000 rpm. The compactness of this device makes it easy to always have it with you.
To start and work, you only need a regular cord (included). Wind it around the axis, pull it with a sharp movement and the rotor has already received the initial acceleration. Further, with smooth movements of the brush, slowly rotate the Powerball, gradually accelerating the movement.
To maintain this movement, you need to apply a force - from small to equal to 15 kg. It is transmitted from the hand to the muscles of the forearm, biceps and triceps. It is this basic property that was appreciated by people who often have to lead an office lifestyle, where body movements are limited only to dragging the mouse across the rug and clogging the keys. As a strengthening of the muscles of the hands, you can spend just a few minutes a day.
Just three to five minutes of intense rotation can easily replace iron kilograms in the gym. At the same time, there is no dangerous load on the joints: it is not necessary to lift weights, therefore, there are no pulled tendons and other injuries.
In addition, the gyroscopic hand trainer is especially convenient in conditions of small space and lack of free time: standing in a traffic jam, watching news or favorite programs, and even doing household chores - use this time to the maximum!
ATTENTION! Causes gym addiction! As soon as he gets into the field of view, how does a hand immediately go after him? Give him a place near the monitor or on the bedside table, and the training itself will turn into a regular one.
Gyroscopic simulator device
To start the gyroscopic hand trainer, you can use the supplied cord (the principle of a boat engine).
Exercises with a gyroscopic hand trainer
There are several fundamentally different ways of training with gyroscopic simulators.
Let's take a look at some videos showing various groups muscles that work during training with a hand trainer.
In each of these exercises, the faster the rotor spins, the more resistance there is inside the ball, and the harder your muscles have to work - thus a more intense workout!
If you are new to gyro training, we recommend that you start slowly and avoid rotating too much at the start. Regardless of your general physical fitness.
Hold the machine with your fingertips only. This way you exercise the muscles of your fingers without the risk of overtraining them.
This is because as soon as you apply less force, the rotor slows down and the load and power are reduced.
Such training is very effective for climbers, mountain bikers, and also for pianists. Indispensable for people professionally engaged in massage.
Wrist workout
Holding the Gyro Wrist Trainer firmly in your hand, increase your speed as you rotate your wrist. This good workout for your coordination. Repeat this exercise clockwise, then counterclockwise. Do the same with the other hand. After a long period of rest due to injury, you can improve the mobility of your wrist.
Such training is very useful in any sport where strong wrists are important: tennis, hockey, cycling, golf. Also this good exercise for rehabilitation after any type of injury or with carpal tunnel syndrome.
Carpal tunnel syndrome is a painful sensation in the wrist that occurs after long periods of typing or typing.
lower forearm workout
Accelerate the rotor while simultaneously trying to fix the hand firmly and firmly. Now the power will automatically come from the muscles in your lower forearm. You will even see how the muscles work and move. The Gyro Trainer is the best training device for improving the performance of the lower forearm muscles.
This is the best way to warm up the muscles before starting your main sports activities. Even while exercising a short time You will feel warmth in your hands. Regular workouts with the simulator prevent inflammatory diseases in elbow joints(epicondylitis, or tennis elbow).
Triceps exercises
Reach out your hand and turn rear surface forearms inward and slightly forward. Speed up the ball. You will feel how the triceps work. This exercise is suitable for those sports where strong upper arm muscles are important: tennis, rowing, rock climbing.
Biceps exercises
Accelerate the rotor while holding the gyro trainer up as you see it in the picture. You will feel the muscles in your upper arm begin to work. This exercise is great for sports where the biceps play an important role: for example, rock climbing, tennis, rowing and many others.
Shoulder Exercises
Stretch your arm to the side and speed up the rotation. This exercise can relieve shoulder pain, and you will feel a real effect all the way to the neck. The only thing that is true in all exercises is that in order to accelerate the gyro machine and maintain the speed of rotation, you must feel the ball.
It helps a lot in concentration and you will improve your body's sense of self.
See video about the trainer:
Carpal tunnel syndrome or carpal tunnel syndrome is pain in the arms, especially in the hand right hand, caused by a long monotonous
work based on flexion-extensor movements of the hand.
The carpal tunnel is very narrow, and the median nerve and 9 tendons of the muscles of the hand pass through it.
The wrist is a relatively small joint, around which are concentrated:
The cause of pain in carpal tunnel syndrome is a pinched nerve in the carpal tunnel. Pinching can be caused by swelling of the tendons passing in close proximity to the nerve, as well as swelling of the nerve itself.
The cause of pinching is a constant static load on the same muscles, which can be caused by a large number of repetitive movements (for example, when working with a computer mouse) or an uncomfortable position of the hands while working with the keyboard, in which the wrist is in constant tension.
This occupational disease affects embroiderers, hairdressers, drivers, sign language translators, programmers, designers, copywriters, typesetters, and other people who constantly
working on a computer.
History of the study of carpal tunnel syndrome
is over 130 years old. It began when Paget first described a patient who developed compression of the median nerve in this tunnel after a fracture that coalesced to form an excess callus.
How to disassemble and repair a gyro trainer
Gyro simulator
Appearance. A cord is wound around the rotor for its initial spin-up.
Gyro simulator is a sports simulator, the principle of operation of which is based on the properties of a two-axis rotary gyroscope.
Purpose
It belongs to the class of wrist simulators, when using which the main load falls on the muscles and joints of the hand. To achieve high degrees of untwisting of the rotor of the gyroscopic simulator, the muscles of the forearm, shoulder and shoulder girdle.
To some extent, this simulator can be attributed to entertainment items (toys), due to its rather unusual properties, demonstrating physical laws in the field of classical mechanics.
Design
It is a small object of spherical shape, which can be firmly grasped by the palm and held by the fingers of one hand of an adult. There are also models of the simulator for children with smaller dimensions compared to the adult model. There is another type of simulator with two diametrically opposite handles on the sides of the simulator body, which are held with both hands at the same time as a steering wheel.
The case contains a gyroscope device. Basically, the case is made of transparent plastic, models with a metal case are less common and more expensive than plastic ones. In the case, as a rule, there is a hole through which access is made to the rotor for its initial unwinding. Trainers without an open part of the rotor have small holes for threading a plastic starter in the form of a thin strip with teeth, which spins the rotor using a rack and pinion.
The main mass of the simulator is a massive rotor, the axis of which can rotate in a strictly diametrical position along an annular groove inside the body. The rotor, in most cases, consists of a combination of plastic and metal; rotors made entirely of metal, as in the case of the body, are found in more expensive models of the simulator.
The ability to disassemble the simulator in parts (for example, to clean it) may or may not be present.
Description of parts
In the simulators, the body of which is made of metal, in a pair, replaceable plastic rings are used, which form a circular groove and on which the rotor axis rubs, and therefore there is no advantage in terms of durability over simulators with a plastic body.
As a rule, a replacement set of such rings is included with a metal simulator along with a restrictive ring.
Peculiarities
Model with rev counter
Some simulators are equipped, or can be retrofitted with an electronic counter that allows you to register the maximum number of revolutions per minute (RPM, eng. revolutions per minute). The current world record - a speed of 16,732 rpm, was set by the Greek Akis Kritsinelis (Greek Akis kritsinelis). He also holds a record force index (number of revolutions in 90 seconds), equal to 21,228 revolutions.
There are luminous models of the simulator, on which several LEDs are installed and a dynamo that generates electricity for their operation.
Usage
The simulator must be held firmly in the hand during use, as the forces of action will try to deflect it into different sides. Do not allow the treadmill to fall, especially while it is in motion.
First, it is necessary to give the rotor a certain minimum kinetic moment. This is done by a sharp and sliding touch of the protruding part of the rotor with some finger (usually a large one) in the direction of rotation. To facilitate starting, a starter is used in the form of a lace, which is inserted into a small hole in the rotor and wound around it along the groove (like a coil), after which it is pulled out for the rest.
When the rotor spins up to 2-3 thousand revolutions per minute, a person holding the simulator in his hand can accelerate it to much higher speeds by making circular movements with a brush.
During the application of a constant external force to the gyroscope, it begins to rotate around some axis that does not coincide in direction with the main axis of the rotating rotor, that is, precess. In this case, the rotation does not occur in accordance with the direction of the external force. The magnitude of the precession is proportional to the magnitude of the acting force. In the event of termination of external influence, the precession ends instantly, but the rotor continues to rotate.
Once the rotor is started, tilting the device will cause one end of the axle to move on the top side of the groove and the other on the bottom side. When the axis of the spinning rotor comes into contact with the top and bottom surface of the groove, it will cause precession and the rotor axis will begin to circle along it. The frictional force between the axis and the groove surface can either speed up or slow down the rotation of the gyroscope.
The greatest acceleration is achieved when the rotor axis begins to “slide” along the groove surface as smoothly as possible. Since the force of friction is very important for this effect, the device should never cannot be lubricated. The maximum speed of rotation of the rotor is achieved by holding the sphere in the hand and constantly maintaining the rotation with the movement of the brush.

The powerball simulator is an effective device that will allow you to easily fully pump your arm muscles. A feature of powerball training is the use of human strength to create and maintain a load on the muscles during the rotation of this sports ball.
Components of a powerball
Powerball for hands is more than compact. Its constituent parts:
- Rotor - an element rotating around its own axis and perpendicular to the plane of rotation of this axis along a circular groove-groove.
- Housing - a covering of the rotor, consisting of two halves held by screws or latches. The function of the housing is to hold the rotor axis in the groove.
- Restriction ring - holds the rotor axle in a diametrical position, preventing it from crashing into a circular chute. It rotates with the rotor.
It is worth noting that for classes you do not have to spend money on a charger or batteries. The device only works by hand.
Benefits of using
The Powerball hand trainer is a revolutionary invention for keeping all muscles in good shape. upper limbs. As soon as you take it in your hand, you will feel serious resistance. The more actively the device is untwisted, the more force will have to be applied to hold it. It is difficult to overestimate its benefits:
- suitable for all age categories;
- they cannot be injured;
- indispensable for athletes (climbers, tennis players, boxers);
- useful for musicians (pianists, saxophonists);
- pumps up the forearms and increases the flexibility of the hands;
- applicable after injuries to accelerate the restoration of joint mobility;
- powerball will get rid of pain in the hands (tunnel syndrome), often due to long work with a computer;
- The expander takes up minimal space, and can easily fit in a woman's purse or pocket.
What are the features of powerball training
The principle of operation of the "gadget" is based only on the laws of physics. Inside the ball there is a gyroscope, which is launched at the beginning of the friction with the help of the included thread or finger.
- From the moment you start the simulator, it begins to spin in the opposite direction from the movement of the hand. The stronger the movement of the device, the more difficult it is to hold it.
- Powerball lessons can be done anywhere. You can rotate a limb with a ball clamped in it at home, in the gym or on the subway.
- Applying efforts during the rotation of the expander, it begins to rotate around a certain axis that differs from the main axis of the rotor. In this case, there is a centrifugal force, as if trying to snatch the ball from your hands.
- Trainers for hand powerball are designed in such a way that sometimes it is necessary to apply a force from one kilogram to 15 kg to continue rotation.
How to start the device at the beginning of work
Perhaps the first launch will confuse you, but getting used to it is a matter of time.
- Insert the tip of the cord into the hole of the rotor, rotating the rotor with your thumb, wind the cord around it so tightly that there is no slack left.
- When you have 4-5 cm of cord left in your hands, stop winding and take the device in a brush so that the thread is at the top. Pull sharply on the free end of the thread. The device will start moving at a speed of 3000 revolutions.
You can wind the device with your thumbs, winding the rotor. In total, you will have to make three full turns, holding it. Release your finger with a sharp movement, then the device will start moving.
Safety regulations
In all safety, try to adhere to the following rules for handling a powerball.
- If you suffer from heart failure or any other heart condition, avoid exercising.
- You cannot touch a moving element.
- Try not to drop or throw the device, as heavy stuffing can damage the inner shell of the “apparatus”.
- To train correctly, avoid getting the ball dirty, make sure that no oily lubricant or liquid gets inside.
- Keep the powerball firmly in your palm during the workout. If it slips out of your hand and falls, then it may not break, but a "knocking" sound will certainly appear.
Exercises with the Powerball carpal expander
If until now you have not encountered expander training, then we strongly recommend starting rotations with low speeds and simple rotations. We recommend several options for exercises to work out different muscle groups.
- For grip and finger strength. Hold the Powerball gyroscopic hand expander with only the tips of all fingers. Activate the mechanism, and after that, with a clamped ball, make circular movements in any direction with a small trajectory. This way you will train, but do not overwork them. This is because with a decrease in the applied rotational forces, the rotor slows down, and with it the load. In the process, the direction of rotation and the hand must be changed periodically.
- To work out the wrist. Grab the machine firmly with your whole hand. commit rotational movements flexing the limb at the wrist. Try to increase the speed when spinning. Make movements both clockwise and counterclockwise. This workout is ideal for dealing with carpal tunnel syndrome and for working out injured wrists.
- For the lower part of the forearm. Hold the expander in your hand, make rotational movements with the entire limb from the elbow to the fingers, while fixing the brush. You will see firsthand how the muscles of the forearm move. This exercise can be an excellent initial warm-up before the main physical activity.
- To work the triceps. Stretch the limb, slightly turning the back of the forearm inward. Twist your hand in small amplitude, feeling how the muscles tense up. This type training is suitable for rowers and tennis players.
- For biceps. Extend your arm out to the side, bending your elbow down. Squeeze the rotor, rotating it with a small amplitude, constantly increasing the pace. Work in the mode that suits you, do not try to start at a fast pace. During this lesson, the biceps swing, which is very convenient for both athletes and office clerks.
- For the shoulder girdle. Stretch the limb to the side, holding the expander in the hand. Twist the arm with the simulator without bending it at the elbow. You will feel warming in the muscles up to the neck.
Powerball is a hand and forearm trainer based on a gyroscope. It is actively acquired not only for sports purposes, but also for the prevention of carpal tunnel syndrome, which has become a real epidemic of the 21st century due to the rampant development of computers and mobile devices. This gyroscopic simulator will tone the muscles of the hands, teach them proper relaxation, will give strength and excellent coordination.
Powerball Benefits:
- ideal biomechanics of exercises;
- treatment and prevention of carpal tunnel syndrome;
- no risk of injury;
- affordable price for any Powerball model;
- durability;
- compactness - the hand trainer fits easily into your pocket.
powerball features
The simulator has a spherical shape, the body is made of plastic or rubberized material, partially covering the rotary gyroscope. The initial movement of the rotor is set using a lace or, if desired, in another way. The more the rotor rotates, the more difficult it is to hold the simulator in your hand.
Basic movements with a gyro trainer
There are three main movements in which the forearms are involved to a greater extent. All of them are shown in these illustrations:
It is not difficult to see that some of these movements are the main ones for certain hand trainers. For example, flexion and extension of the fingers is more related to classic expanders. Biomechanically, this is a very effective simulator, but it is able to load the forearms with only a few basic movements. Powerball combines all possible types of load that allow you to comprehensively influence the development and condition of the forearms. This is kind of the only "basic" hand trainer.
The load will always depend only on your current condition of the forearms. The maximum rotation speed is limited by the strength of the forearms. This is how the manufacturer was able to completely eliminate the possible risk of injury. Now it is the safest hand trainer.
Which model to choose?
The online store has a huge collection of gyro trainers, you can choose and buy the Powerball to your liking - the classic model with a rubber band or tape, rubberized versions and other solutions:
- Classic. In most cases, a special rubber strip is applied to the case for a more durable and comfortable hold. There is a display with the calculation of the speed of revolutions, duration and total record. Made of plastic or metal;
- With special tape. Quite often, athletes complain about the fear of dropping the projectile. Naturally, this leads to a decrease in the number of revolutions of the rotor. To get rid of such a phobia, the manufacturer produces special models with a rope that is attached to the wrist. Thus, even with an accidental relaxation of the arm, the simulator will not fall;
- Special fortified. The case has a denser rubber coating;
- Metal. Have a spectacular appearance and increased weight;
- With backlight. Allows you to train in the dark. Neon lights and high rotation speeds are another way to spruce up your workouts and avoid monotony.
"Gyroscope Ball" (Gyroscope Bol) is a unique gyroscopic hand trainer, expander for men and women, for children and adults, as well as a great accessory for entertainment! With it, it is easy to train arm muscles, improve your own dexterity, without tiring and long workouts.
Recently, the hand trainer Gyroscope Bol has been in great demand among representatives of various professions. The secret of such popularity is in effective training muscles of the hand, forearm and shoulder with just one such device. A small ball weighing 250-300 gr. able to create a power load from 3 to 20 kg! Daily exciting exercises with a wrist simulator increase arm endurance, relieve joint pain, and help to quickly rehabilitate after injuries and operations. It's no wonder that people are in a hurry to buy Gyroscope Ball (Powerball) professional athletes, musicians and representatives of professions associated with heavy physical exertion. It will also be useful to people whose work is related to working at a computer.
Watch the video:
The hand trainer is a sphere made of durable transparent plastic with a silicone rim. Inside the sphere there is a gyroscope (built-in rotor), the rotation of which is started with the help of special shoelaces or untwisted with fingers. In the process of training, you need to increase the speed of rotation of the sphere, while holding it in your hand, and overcome the resistance of the simulator. The unique principle of operation provides a tangible effect from training with the simulator.
Just three to five minutes of intense rotation can easily replace iron kilograms in the gym. At the same time, there is no dangerous load on the joints: it is not necessary to lift weights, therefore, there are no pulled tendons and other injuries. In addition, the gyroscopic hand trainer is especially convenient in conditions of small space and lack of free time: standing in a traffic jam, watching news or favorite programs, and even doing household chores - use this time to the maximum! And the Gyroscope Bol itself fits into a pocket or handbag without any problems.
Another incomparable advantage of such a simulator is its external attractiveness. Imagine what others would think about a person who came to the office or club with dumbbells! And with the Gyro Ball, the effect will be radically opposite: it will attract interest to its owner and involve everyone in the training process, during which you can even hold a competition and determine the strongest and most skillful participant.
Application:
- Insert the supplied lanyard into the groove of the inner ball of the gyro trainer, wrap it around the inner ball and pull the lanyard sharply. Put the device in your hand and rotate it, increasing the speed of the gyroscope.
Be careful! carpal expander spins very fast, do not stop it with your hands.
After the start of work, the "Gyroscope Ball" will literally "come to life" in your hands and begin to break out in different directions. Your task is to increase the speed of its rotation while holding it in your hands.
Exercises with a gyroscopic hand trainer.
There are several fundamentally different ways of training with gyroscopic simulators.
Let's look at a few videos that demonstrate the various muscle groups that work when training with a hand trainer.
In each of these exercises, the faster the rotor spins, the more resistance there is inside the ball, and the harder your muscles have to work - thus a more intense workout!
If you are new to gyro training, we recommend that you start slowly and avoid rotating too much at the start. Regardless of your general physical fitness.
Finger and grip training.
Hold the Gyro Trainer with your fingertips only. This way you exercise the muscles of your fingers without the risk of overtraining them. This is because as soon as you apply less force, the rotor slows down and the load and power are reduced. Such training is very effective for climbers, mountain bikers, and also for pianists. Indispensable for people professionally engaged in massage.
Wrist workout.
Holding the Gyro Wrist Trainer firmly in your hand, increase your speed as you rotate your wrist. This is a good workout for your coordination. Repeat this exercise clockwise, then counterclockwise. Do the same with the other hand. After a long period of rest due to injury, you can improve the mobility of your wrist. Such training is very useful in any sport where strong wrists are important: tennis, hockey, cycling, golf. It is also a good recovery exercise after any kind of injury or with carpal tunnel syndrome. Carpal tunnel syndrome is a painful sensation in the wrist that occurs after long periods of typing or typing.
lower forearm workout
Accelerate the rotor while simultaneously trying to fix the hand firmly and firmly. Now the power will automatically come from the muscles in your lower forearm. You will even see how the muscles work and move. The Gyro Trainer is the best training device for improving the performance of the lower forearm muscles. This is the best way to warm up the muscles before starting your main sports activities. Even when exercising for a short time, you will feel warmth in your hands. Regular training with a simulator prevents inflammatory diseases in the elbow joints (epicondylitis, or tennis elbow).
Triceps exercises.
Extend your arm and turn the back of your forearm inward and slightly forward. Speed up the ball. You will feel how the triceps work. This exercise is suitable for those sports where strong upper arm muscles are important: tennis, rowing, rock climbing.
Biceps exercises.
Accelerate the rotor while holding the gyro trainer up as you see it in the picture. You will feel the muscles in your upper arm begin to work. This exercise is great for sports where the biceps play an important role: for example, rock climbing, tennis, rowing and many others.
Shoulder Exercises.
Stretch your arm to the side and speed up the rotation. This exercise can relieve shoulder pain, and you will feel a real effect all the way to the neck. The only thing that is true in all exercises is that in order to accelerate the gyro machine and maintain the speed of rotation, you must feel the ball. It helps a lot in concentration and you will improve your body's sense of self.

Currently, a huge number of people, if not yet, are prone to the so-called carpal tunnel syndrome. The risk group includes people of various professions and hobbies, for example, drivers, artists, photographers and, of course, people who work a lot at the computer, they are also the most susceptible to this disease. In the advanced stage of CTS (Carpal Tunnel Syndrome), inpatient treatment may be required up to surgery (a special operation to extract excess fluid from the joints). Well and The best way solve the problem - never face it. To do this, you need to engage in prevention through a warm-up or specialized devices, such as a gyroscopic simulator.
Today I will talk about 3 models of Powerball - Classic, Fusion and Autostart. These are one of the most popular models on this moment. They can also cover the entire line of hand trainers, with the exception of metal devices. Read more under the cut.
Packaging and equipment
The Powerball Classic and Fusion models come in blister packs, while the Autostart model comes with a cylinder-shaped clear plastic case.
On the reverse side of the "blister" packages are instructions for starting the simulator and a photo of a man who pumped his bicep with a gyroscopic simulator with the indicated muscle groups that are affected by Powerball.
But the most interesting is the packaging of the Autostart model. To begin with, to open it, you need to remove the bottom of the flask, which houses the Mini-CD (23 MB) with detailed instructions(Russian available) as an HTML page.
Actually "interestingness" lies in the practicality of this box. Disconnecting upper part from transparent plastic, the lower one turns into a stand for Powerball, as it turned out - an extremely convenient and necessary thing, because because of its rounded shape, “balls of power” often like to roll off the table.
The delivery set for the Classic and Fusion models consists of the simulators themselves, brief instructions, Mini-CD and a pair of laces to launch the subject. Accordingly, the Powerball Autostart has everything the same except for the laces.
Each of the devices comes with a lifetime (!) Warranty for the rotor and speed counter. At the same time, in the event of a breakdown, a repair is promised within 14 working days or a replacement of the product.
Appearance
Externally, the gyroscopic simulator is a small spherical object. In most cases, the case is made of thick plastic of various colors and degrees of transparency. There are also metal models, but they are positioned as advanced devices, respectively, and their price is higher.
In the upper part there is a revolution counter or a seat for it, since there are models on sale both with and without a speed counter. The price difference for younger models is around $20. In any case, even if you initially purchase a model without a counter, you can install it at any time. Business there for 5 minutes, unless you have to overpay a little and give back not 20, but 25 dollars.
Due to the open lower part, you can see the "naked" rotor. The latter has a hole for the thread with which the simulator is launched. In addition, the Powerball body is framed with a rubber pad for a more confident hold of it in your hand.
The exception is the Autostart model, for which you need to “wind up” the rotor to start, and for better grip with your fingers, two rubber pads are provided.
Also worth mentioning is the backlight. This in these simulators can be called dynamic, since the brightness of the glow changes depending on the speed of rotation of the rotor. Most models in the Powerball line have a single-color glow, with the exception of one of the heroes of our today's review - Powerball Fusion. The color of its glow smoothly changes from red to blue as the RPM increases. The transition to blue is carried out when the speed reaches 8000 rpm.
The principle of operation and guts
The principle of operation of the subject is quite simple. The device is based on a gyroscope, consisting of a rapidly spinning rotor enclosed in a plastic sphere. You can set the rotor in motion with the help of a special rope included in the kit, then you need to make circular movements with your hand to increase the speed of the rotor. The simulator must be firmly held in the hand during use, as the forces of action will try to deflect it in different directions. During the application of a constant external force to the gyroscope, it begins to rotate around some axis that does not coincide in direction with the main axis of the rotating rotor, that is, precess. In this case, the rotation does not occur in accordance with the direction of the external force. The magnitude of the precession is proportional to the magnitude of the acting force. In the event of termination of external influence, the precession ends instantly, but the rotor continues to rotate.
Once the rotor is started, tilting the device will cause one end of the axle to move on the top side of the groove and the other on the bottom. When the axis of the spinning rotor comes into contact with the top and bottom surface of the groove, it will cause precession and the rotor axis will begin to circle along it. The frictional force between the axis and the groove surface can either speed up or slow down the rotation of the gyroscope. The greatest acceleration is achieved when the rotor axis begins to “slide” along the groove surface as smoothly as possible. Since the friction force is very important for this effect, the device should never be lubricated. The maximum speed of rotation of the rotor is achieved by holding the sphere in the hand and constantly maintaining the rotation with the movement of the brush.
A more detailed physical principle of the Powerball can be found on Wikipedia, and we are moving on to disassembling the device. First you need to remove the rubber pad. 
Then we unscrew the two diametrically opposite cross screws. 
Next, we need to disassemble the body, which consists of two halves. To do this, you need to place the Powerball on a hard, flat surface (as shown in the picture below) and naturally hit the seam sharply. As a result, the halves should separate. 
If it didn’t work out, then try to put pressure on it with a book with a hard cover, under load, the parts of the case should bend a little and separate accordingly. The only thing I do not advise is to “pick” the seam with a screwdriver or other metal objects. To disassemble, you will disassemble it, but at the same time, with a high probability, unpleasant traces-dents will remain, like mine: 
So, before us appeared the rotor, well, or part of it. We no longer need the lower half, so we remove it and take the rotor from the upper part of the case. 
By the way, about the upper part of the case, it (optionally) houses a speed sensor. To get it, you need to use a flat screwdriver to pry the latch with which it is fixed. 
The bottom part of the board is completely empty, only a couple of unsoldered pads for additional components are visible. To get to the back side, you need to unscrew 6 small screws, one of which is hidden under the sticker. 
On the upper part: "microcircuit-blot", reed switch (counts revolutions) and all the necessary strapping. The electronics is powered by two GP377 batteries, from which the counter, according to the manufacturer, will work up to 2 years. 
We continue the disassembly and remove the circular groove from the axis of the gyroscope. And be careful here. On both sides there are sealing gaskets that tend to get lost due to their small size. 
The rotor consists of 4 parts: an axis, a metal base, a plastic shell and a board with LEDs (if the model has a backlight). 
The backlight is powered by a built-in dynamo, so no batteries are needed. 
The internal arrangement of other models is identical to that discussed above. The only exceptions are the metal Powerball and the Autostart version, which has a special mechanism for starting the rotor.
Fast start
Starting the simulator is extremely simple. All you have to do is insert the supplied rope into the groove on the rotor, then pull it out with a sharp movement, thereby giving rotation to the rotor. Next, just spin the Powerball slowly in a circular motion hand (namely, a brush). The main thing is not to start with quick short wrist movements, otherwise you will not be able to catch the rhythm, and it will be difficult to spin the ball correctly. In the video below, I was a little worried, so the start was, let's say, not perfect.With Powerball Autostart it's even easier. To start the simulator, you need to "wind" the rotor in the direction specified by the arrows on it. Then unwind in the same way as the previous "ball".
For conventional models, there is another way - to start the rotor with a sharp movement of your finger along the axis of the rotor, but here you need to get the hang of it. Even after two weeks of active use, I do not always succeed.
In use
Carpal tunnel syndrome is a lesion of nerve tissue (neuropathy) due to some unfavorable conditions. Unfavorable conditions can be very different - usually it is the monotonous work of the brush or a long stay in unnatural positions. Habrahabr has repeatedly discussed this topic. I strongly recommend that you familiarize yourself with the works of my colleague and habrauser, that this disease is sorted out on the shelves, as well as methods for its prevention.
In general, the scope of Powerball is quite extensive and is not limited to CTS prevention alone. It can also be used to repair damaged ligaments and tendons after hand injuries, dislocations and fractures. In such cases, it is recommended to rotate the Powerball for just a few minutes a day, but in such a way that its built-in rotor operates at a limited speed, that is, no more than 5-6 thousand revolutions per minute.
But the application possibilities do not end there. "Balls" equipped with counters enable people to compete in "who will wind up the most." Thus, the obligatory warm-up becomes even more exciting. Moreover, the presence of an opponent nearby is not required. On the official website of NSD (Powerball manufacturer) there is a special table in which records from all over the world are entered (representatives of the CIS countries are also present there).
Now with regard to the operating modes of the counter. There are 5 of them in total. Switching is carried out using the FCN button, and switching on and resetting is done using ON / CLR. In the first mode, the number of revolutions of the rotor that it has completed from the moment of the last start to the moment of stopping is counted.
The second mode is responsible for measuring the speed (RPM per minute) in real time.
The third and most commonly used mode is the display of the maximum RPM (High score), i.e. this setting freezes your record and displays it until you reach a higher score or reset it with the ON/CLR button. As soon as you start to rotate the simulator, the counter automatically switches to the fourth mode (New high score) - the counter shows the highest rotation speed achieved since the last start. If you have surpassed your previous record since the last start, the number on the counter will flash, and the new record will be stored in memory as soon as the rotation of the rotor stops. If your current result less than the record, it will be displayed on the screen until the rotor stops, after which the High score mode will turn on again.
And, finally, the last setting is the measurement of the force index, its essence is in counting the number of revolutions made in a certain period of time (30, 60 and 90 seconds). A great way to measure your pussy strength (endurance?) with a friend.
The display turns off by itself after 40 seconds of inactivity.
Speaking of records, it is worth mentioning one of the most seasoned "twisters". Greek Akis Kritsinelis is an absolute champion in all possible modes and uses of the gyroscopic simulator. Eg, maximum speed to which he was able to overclock the Powerball was 16765 RPM. The video below confirms this, there are other records on the channel. Well, I already gave a link to the table with champions above.
