DIY repair of Almag

Almag 01 is a device that is used to treat many diseases. This device costs about 8-9 thousand rubles. The principle of operation is a traveling magnetic field that accelerates the blood. It consists of a control unit and four inductors, which are connected in series and create a magnetic field.

The weak point in this device is the wires connecting the coils in series. I will tell you how to repair it. In the photo below, only one inductor is working on the device. This is evidenced by only one lit LED indicator.

The coil that works is the very first in the chain of inductors, therefore, the wires are intact to it. First, let's replace the wires that broke from the first coil to the second. For this we will analyze both. Previously, there were stickers on the inductors from the side of the LEDs, on this device they have already been removed and the bolts are visible under them, and on the reverse side of the nut.

We unscrew them, pry them off and half with a slotted screwdriver. It is better to hook it at the point of entry into the body of the rubber cuff.

There are two options. The first is to ring the green wires with the tester and re-solder the broken ones. The second is to re-solder all the green ones so as not to disassemble them again.

I took the second path. We sequentially unsolder each conductor, take it out and replace it with another piece of wire. It is better to take a stranded wire and about the same thickness as the original. A thicker wire is more difficult to push through and the covers may not close in the future. The sequence of actions is as follows:

1. we solder the wire on one side
2. twist with new
3. pull through the cuff
4. solder on one side
5. cut and solder on the other

I only had a thick wire, so I had to tinker to get it through.

After the wires are replaced to the second inductor, turn on and check. If both indicators light up, then everything is ok. Go ahead, collect the first and disassemble the third.

Here, repairs have already been carried out earlier, we only change the green wire and check. Everything worked, all four indicators light up in sequence. Putting it up in reverse order.

I did not take pictures of all the lit indicators, they light up sequentially. In the photo, the last inductor in the circuit is on. It is clear that everyone else is working before him. The cost of the new device and the cost of the conductors are not commensurate, and in this case, one does not need to have strong knowledge in radio electronics! Good luck with the repair!

If you cannot repair it yourself, you can contact me. Repair will cost much less than a new device. You send the device by mail to the mailing address indicated by me, and you will receive a repaired one back. Repair cost 1000 rubles. will be included in the cash on delivery. Leave a request for repair through the feedback form.

Upon examination, it was revealed that the cable coming from the first inductor

pulled out of the rubber bushing of the first inductor to the block and held

on five conductors, two of them broke

Disassembling the inductor is not difficult.

Remove the sticker from the LED side underneath the two bolts, unscrew

We see a board with wired conductors, sketching where which one goes

we unsolder the conductors pull the cable, cut it off, remove the top

cable insulation by five centimeters. We clean the conductors

we insert the cable into the bushing with rubber glue we unsolder the conductors

There is no core in the coil (I read somewhere that there is some special core in the coil)

Another Almag most often the wires are cut in the vicinity

the first inductor We disassemble the block and the inductor ring the wires

those that do not call are pulled from the side of the inductor easily pulled out

measure off cut with a margin closer to the block

We do not pull the repair to close the signal wire with a common

will lead to failure of the electronic unit

In this diamond, a break occurred between the inductors

put on heat shrink and soldered

The LED is powered in series through the coil

inductor parallel to the LED is a 2.2 ohm resistor

no longer needed a tap from the coil

field workers P5NK50Z replacement from the manufacturer

Krasnoyarsk repair Almag-01 t. 8 933 332 3164.

The first time this magnetotherapy device (fig. 1) brought about a year ago with the words "works for about a minute and turns off." It turned out that the self-healing fuse had increased internal resistance; after turning on the device, it began to heat up and after a while broke the power circuit. The same replacement fuse was not found, so an MLT-0.5 resistor with a resistance of 1 Ohm was installed in its place.

The second time the same device was brought quite recently - from constant bends, the wires broke and burned out in the places where the cable was supplied to the inductor coils and to the electronic unit (fig. 2). The repair consisted of removing the broken off conductors and re-soldering the cable.

The network can easily find a diagram of the old version of Almag-01, where meters and decoders of the 561 series are used (available in the appendix to the text). The brought device was already assembled on the 12F509 PIC controller, so during the first repair I had to copy the circuit diagram from the printed circuit board (fig. 3).

Elements FU2, VR1, C2, FU1, Tv1, R2 and R8 can be attributed to the 220 V power supply circuit - this is both protection of the device from possible overvoltage in the network and protection of the network from impulse noise that occurs in the device.

The VD2 diode passes only positive half-waves of the mains voltage, and after it there is no storage capacitor, and this suggests that the entire power section (transistors VT1 ... VT4 and their load in the form of inductor coils) works only during the appearance of these half-waves.

Their presence is also controlled by the PIC controller along the R1, R3, R7, VD5, C5 and R6 circuits. The microcircuit is powered by elements C1, VD3, VD4, C3, R4, VD6, C4, VD11 and C6.

Negative half-waves, passing through the VD1 diode and being limited by the VD12 zener diode at a level of 3 V, cause the green LED HL1 "MAINS" to glow.

The yellow HL2 LED (OPERATION mode indicator) lights up when the PIC program is started. While the program is running, a "running" pulse appears at pins 3, 5, 6 and 7 of the microcircuit, which controls the transistors VT1-VT8. The power supply of the power transistors VT1-VT4, as mentioned above, occurs with positive high-voltage pulses, and VT5-VT8 are supplied with a constant voltage of +12 V (VD4, C3).

The inductor coils themselves consist of a series-connected multi-turn coil and a 2.2 Ohm resistor (seen on fig. 2). Parallel to the resistor, there is a green LED that glows when voltage appears on the coil.

The instructions for the Almag-01 apparatus indicate that the pulse flowing in the inductor coil has a duration of 1.5-2.5 ms and follows with a frequency of 6.25 Hz (instructions are attached to the text).

To check the indicated time intervals, sensors made in the form of multilayer coils (fig. 4), and the voltage induced on them was fed into the sound card of the computer for analysis in the SpectraPLUS program.

On the fig. 5 above shows the voltage from the first coil, and below - from the second. It can be seen that the pulses are shifted by a quarter of a period. Also noticeable interference from the appearance of the third and fourth impulses. The repetition rate, as indicated in the instructions, is close to 6.25 Hz.

On the fig. 6 and fig. 7 you can see the position of the pulses in one of the coils relative to the mains voltage and the shape of these pulses in more detail. The approximate duration of that part of the pulse that can be called "positive" is close to the indicated 1.5-2.5 ms. The "negative" part is most likely the EMF that occurs in the coil when the transistor is closed.

Finally, a few overview photos. On the fig. 8, fig. 9, fig. 10 - general view of the electronic unit of the device with the cover removed, on fig. 11 and fig. 12 - for transistors STP5NK50Z and PIC controller 12F509, for fig. 13 - to the back of the printed circuit board.

On the fig. 14 - a view of the small printed circuit board that is located in each inductor. All outlets are numbered and correspond to the numbering of the pins in the electronic unit (on fig. 10 on right). The coil itself is wound with a wire with a diameter of about 0.15 mm on a plastic frame with an approximate inner diameter of 56 mm. Winding width - 6 mm, height - 5 mm.

Magnetic therapy apparatus "Hottabych"

Magnetotherapy Is a method of physiotherapeutic treatment based on the effect on the body of low-frequency constant or pulsed magnetic fields with specified parameters. The magnetic field influences the body due to its paramagnetic and diagmagnetic effects.

Factory devices are very expensive, but making a similar device yourself according to a simple scheme and from available inexpensive parts is available to every radio amateur.

It has been found that it increases the permeability of our cell membranes, accelerates redox reactions, enhances the activity of enzymes and activates local blood circulation. Magnetic fields relieve pain and inflammation, reduce swelling in tissues, reduce the activity of the blood coagulation process, stimulate regenerative processes in tissues (especially in bone and cartilage) and improve their nutrition.

Magnetotherapy provides pressure reduction in the saphenous and deep vein system, in the arteries. At the same time, the vascular tone increases, due to which there are indications for the use of magnetotherapy in the treatment of hypertension and to reduce the load on the heart. Microcirculation in the affected area is intensified, due to which capillary blood flow is accelerated, the contractility of the vessel walls is improved, and their blood supply increases. The microcirculatory bed expands, which leads to the emergence of favorable conditions for the opening of shunts, capillaries and anastomoses.

Magnetotherapy improves epithelial and vascular insight, therefore, the method is used to relieve edema and accelerate the resorption of injected drugs. In this regard, therapy has indications in the treatment of wounds, injuries and their various consequences.

Constant, alternating and traveling magnetic pulsed field enhances metabolic processes in fractures, osteo- and fibroblasts appear faster, bone substance is more actively formed, due to which this method has proven itself well in the treatment of fractures.

• bleeding;
• acute thrombosis;
• systemic blood diseases;
• thromboembolic and recurrent complications of aneurysm of the heart of the aorta and large vessels;
• cardiovascular failure from stage 2 and above;
• stable angina pectoris of functional class 3 and 4;
• serious heart rhythm disturbances;
• acute myocardial infarction;
• the patient has a pacemaker;
• diseases of the central nervous system, accompanied by sharp excitement;
• mental disorders;
• claustrophobia (with general exposure);
• acute period in disorders of cerebral circulation;
• the presence or suspicion of the presence of malignant neoplasms;
• active tuberculosis;
• general serious condition of the patient;
• acute stage of various infectious diseases;
• fever;
• exacerbation of chronic inflammatory processes;
• gangrene;
• thyrotoxicosis;
• individual intolerance.
• Children under one and a half years of age do not receive magnetotherapy even locally, and under eighteen, it is not recommended to apply a general effect.

Currently, there are many devices and apparatus for magnetic therapy on the market: ALIMP-1, AMO-ATOS, MAG-30, ALMAG and others. Their main disadvantage is the cost, which varies from several thousand to several tens of thousands of rubles. In the conditions of Russian reality, for many sufferers, these are exorbitant figures.

Therefore, I propose a diagram of a magnetotherapy device codenamed Hottabych, made on an inexpensive and affordable element base, costing about several hundred rubles. This device can be assembled by any even a novice master with his own hands.

Transistor VT3 - KT815, KT817 or similar reverse conduction (in the KT814 circuit - a typo).

The maximum magnetic field strength is such that it attracts metal objects at a distance of 9-10 cm, therefore, this device should be used from the minimum values, gradually increasing the value of the magnetic field until the pain syndrome is relieved, focusing on the frequency and voltage on the LED, if it is important for someone a more accurate value, you can set a dial or digital indicator.

It is noticed that the frequency of several hertz is the most effective (in the proposed device it is modulated by the network frequency), but in principle, it is individual for each person separately. Coil L1 is taken from a second magnitude starter

220v with an open magnetic core and filled with epoxy for safety, it is connected to the device with a flexible cable 1.5 squares in double insulation. The device is compact, but if someone does not like the high output voltage, then you can replace the transformer with a more powerful one (100 W) with an output voltage of 24 volts and power L1, naturally with a nominal value of 24 volts, from the KBSP2510 bridge connected to this winding. Dimensions and weight will increase significantly.

I cannot but mention the contraindications for the use of physiotherapeutic methods, including magnetotherapy: blood clotting disorders; problems with hematopoiesis; acute stage of thrombosis; severe cardiovascular diseases: myocardial infarction, heart failure, angina pectoris, aneurysm of the heart, blood vessels; arrhythmia; use of a pacemaker by patients; disorders of the central nervous system; increased excitability; mental disorders; malignant tumors; tuberculosis; low blood pressure; pregnancy; age up to one and a half years.

Magnetotherapy is gaining momentum successfully. And although it is not universally recognized as a medical method of therapy (for example, in the United States), in Russia it is officially recognized and used in public clinics and private practice. The effectiveness of the method has been confirmed by many clinical trials, although scientists still have work to do.

The magnetic therapy apparatus, the scheme of which I presented here, brought noticeable relief to my loved ones in case of already unbearable joint pain. We resorted to his help, since the effect of the procedures in the clinic is lost on the way to them and walking on floors, and for some reason the procedures themselves became paid.

The production of medical equipment is a licensed activity. As you understand, I do not possess such a license and the use of the device presented in my diagram is carried out at your own risk and peril, although taking into account the contraindications and our Russian reality (ecology, stress, food, indifference of doctors ...) it will not bring more harm ...

Unfortunately, the self-help principle is becoming more and more relevant in our country, and if the proposed apparatus helps you, then I will be very happy about it.

Any available radio station or radio transmitter that connects to the described device is installed inside the garage or other protected object. If the protected area is violated, the circuit generates radio control signals and a special tone signal, which is transmitted to the remote receiver and triggers the alarm. More details ...

When working on an amateur radio station, a radio amateur often needs to know exactly the frequency to which his transceiver or receiver is tuned in order not to go out of range or to fine tune to a predetermined frequency.Mechanical scales do not provide such an opportunity, therefore, electronic scales have to be designed. More details ...

How to check a light bulb, switch, fuse ...?

For checking a fuse, light bulb, boiler, extension cord, etc. You don't have to buy an expensive multimeter. You can assemble the simplest probe on one battery yourself in a few minutes.

1) The device generates an E5 error. The main emitter does not work, only the “Activation” LED is on. The quartz is working, pulses from DA2 arrive at the RXD and TXD DD1 inputs, there is + 5V on DD1, there is + 12V on the board (I have, however, the tester shows 18.3V). And there are no pulses at the inputs of DD3-DD6. What could be the problem?
And further.
2) What is the + 57V on the main emitter board? When do they appear there?

At the moment, the Almag-01 device can be purchased at a special price. The offer is limited and only available through this link. Don't miss your chance, there is a limited number of products left!

The innovative device Almag 01 is a unique device that is able to relieve the sensation of pain and reduce drug treatment by almost half. The principle of operation of this device is quite simple. The main impact is produced by generating a traveling pulsed magnetized field. It acts on charged particles that are in the human body. Magnetic radiation is capable of affecting their work, which is followed by a reflex reaction of human organs and tissues. It is in them that the points are located that are biologically active.

The set comes with the device:

• A cord that supplies the device with energy from a 220 V network;
• Round inductors, with the help of which magnetic radiation occurs;
• Cable extending from the emitter;
• Electro-distribution block.

Important! At the time of purchase, before making a payment, you must check the presence of all components.

It is quite simple to check the operability of the Almag 01 device.

1. We connect to a 220 V outlet.
2. We check the status of the indicator lights, they should light up green.
3. 2 lights on the block should light up. One of them has a green light, which means it is connected to the network. The other light has a yellow light to indicate the safety function and the standby timer. When the device is started, all two lights should be on.
4. The device comes with a special test indicator, with which you can check the magnetic coils. When the device is turned on, you need to apply the indicator to the surface of the working circle, it should glow green. In the event that it does not respond, then this means that the magnetic disk is defective.

Important! It is always necessary to check the device before purchasing. Regardless of how you want to purchase this device.

After the device is connected to a 220 volt network, current pulses are created in a block that distributes electrons. In order for the therapeutic effect on the affected areas to begin, current pulses must pass through all four coils, which in turn emit magnetic pulses. During a session of magnetic therapy, there is a constant movement of the running magnetic field with the direction from the first to the fourth coil.

Almag 01 provides the effect of a magnetic field on the human body with a depth of 8 centimeters. This depth makes it possible to act on diseased organs located far from the surface of the body. It should be noted that this function is very attractive for a home-use device.

Magnetic waves affect cellular metabolism, which contributes to the rapid recovery of affected tissues and organs. In addition, the cellular biofield and the balance of the entire human body are normalized.

The magnetic field, which is created from the operation of the device, ensures rapid cell regeneration, brings the brain cells into working condition, and relieves of arrhythmic seizures.

Almag 01, by its effect, blocks nerve impulses, which allows you to reduce muscle tension and eliminate pain.

The detailed operation of the device is described in the attached instruction card, which is always in the box with the device.

It happens that, for one reason or another, the device stops performing its functions. This may be a partial breakdown, for example, a failure of one of the coils, or it may mean a complete failure of the device system.

Important! In no case should you delay the repair procedure, even if it is a minor breakdown, because your health is at stake.

Each device, including Almag, has a warranty period. The Elamed company provides a warranty period of 12 months. During this period, Almag repairs are carried out free of charge in official specialized centers.

There are cases when the free restoration of the device is not carried out. These include:

1. Traces of an autopsy were found on the device.
2. The components and internal filling of the apparatus have been changed.
3. During the inspection, traces of damage of mechanical origin were found.
4. After opening by a specialist, traces of liquid were found.
5. During the examination, it was revealed that the connection of the device was not made according to the rules, and the socket did not correspond to the permitted voltage.

To prevent this, all the prescribed operating rules must be observed. These instructions are spelled out in the applied instruction card. In addition, the operating time of the device depends on the correct handling of the device. The manufacturer declared a service life of more than 5 years with constant use.
