Electronic bite signaling device electrical circuit. Homemade electronic bite alarms

All experienced fishermen know how difficult it is sometimes to peer into the float for hours, trying not to miss the bite. The glare of the sun and the wind hurt the eyes, the body stiffens from immobility. And fishing at night, when the float is not really visible?
The perfect solution to all these problems - electronic bite alarm, which can be assembled at home in a few evenings. There are probably a lot of schemes, tips and recommendations on the Internet for making such devices, but many of them are rather dubious. We present you the most reliable, time-tested mechanisms.

Preparation for work

Before you start making an electronic bite alarm with your own hands, it is advisable to acquire the necessary tools and materials. Of the tools you will need: wire cutters or pliers, soldering iron, multimeter, knife. The choice of materials and parts completely depends on which of the described types of signaling devices you will work on, but in any case you will need: solder and flux for soldering, wires with a cross section of 0.15 ... 0.5 mm, finger batteries, LEDs or light bulbs (they can be obtained from old flashlights or garlands), a button or toggle switch for turning the device on / off, plywood or thick cardboard for making body parts, electrical tape and glue.

The simplest light indicator

For creating light indicator no special knowledge in the field of electronics, no expensive parts are required. The electrical circuit will consist of only three components - a power source (an ordinary finger-type battery is fine), an LED or incandescent lamp from an old 1.5-3 volt flashlight and any type of sensor. For now, consider the application as a sensor closing reed switch, and at the end of the article you can read about other possible types of sensors. So, the reed switch is a glass bulb, inside of which there are movable and fixed metal contacts. The principle of operation of the reed switch is simple - when a magnet is brought to the body, the contacts close and an electric current can pass through the device. It is most logical to solder the circuit by surface mounting, although you can do without soldering at all. If you are using an LED, pay attention to its polarity. The signaling device is fixedly mounted in any housing of a suitable size, while the magnet is fixed inside the housing not far from the reed switch on a flexible springy strip, for example, galvanized. Lead to a magnet extra line so that when it is pulled, the magnet approaches the reed switch and closes it. The second end of the additional fishing line is attached to the main fishing line with a clip-clip from headphones or an ordinary clothespin. Now the result of any bite will be a bright glow of our signaling device.

Required radio components:

• Battery type AA or AAA - 1 pc.
• Closing reed switch

Improving the mechanism

A light indicator is a great solution for night fishing, but does not eliminate the need for constant eye contact with the device. A combined signaling device will help to solve this problem - in addition to the light indication, it will give sound signals.

The principle of operation of the device and the drive mechanism will remain unchanged, but you will have to work on the circuit. In parallel with the light source, it is necessary to connect a circuit responsible for generating sounds, for example, multivibrator, capable of making the speaker "beep" at different frequencies. A classic multivibrator circuit based on two bipolar transistors of the same structure is suitable (it is better to use transistors n-p-n structures, for example, well known to all radio amateurs KT315). The capacitors used are electrolytic, when connecting them, do not forget to observe the polarity and make sure that the maximum voltage allowed for the capacitor is not exceeded (capacitors of 16 volts and above can be safely used). Resistors are suitable for any type, with a power of 0.25 watts. The capacitance of the capacitors and the resistance of the base resistors will set the frequency of the sound, it is better to determine them by selection or initially install tuning resistors. We will replace one of the resistors connected to the collectors of transistors with a speaker with a resistance of 8 ohms and a power of at least 0.5 watts. By combining multivibrators with different parameters, various complex sounds can be achieved. You can even find schemes to imitate the singing of a nightingale or the mewing of a cat. Whichever scheme you choose, you will most likely have to pick up another current source - perhaps a pack of several batteries or an old mobile phone battery.

Required radio components (when using a simple multivibrator):

• Battery type AA or AAA - 3 pcs
• Closing reed switch with a resistance of not more than 200 Ohm - 1 pc.
• LED or incandescent lamp for rated voltage 1.5-3 V - 1 pc.
• Resistor resistance 100 ... 500 Ohm (pick up) - 1 pc.
• Resistor resistance 10 ... 50 kOhm (pick up) - 2 pcs
• Capacitor electrolytic with a capacity of at least 10 microfarads (select) - 2 pcs
• Transistor bipolar (we recommend KT315, KT3102 or BC547) - 2 pcs
• speaker resistance 8 Ohm - 1 pc.
• toggle switch or slide switch (light/sound switching)–1

Video lesson

If you have an old broken one quartz alarm clock, do not rush to throw it away - the part of its circuit responsible for the sound supply may well help you in creating an electronic bite signaling device. The principle of operation of such a mechanism is similar to that described in the previous section, with the only caveat that instead of a multivibrator, an alarm sound module is included in the circuit. Technical documentation or a multimeter will help determine the necessary contact points on the board. The reed switch acts as a sensor, as before.

Can be used as an alarm clock pager, doorbell, children's toys- any simple device capable of making sounds. Each of them has its own disadvantages and advantages, but the principle of their use is the same - we find and connect the section of the circuit we need.

At the end of the last century, they were very popular musical postcards . If you still have one, the manufacture of a bite signaling device will be much simpler, because the postcards used a similar principle of operation. Having disassembled the postcard, you will find the same reed switch, a board responsible for generating sounds and a piezoelectric element - the simplest sound emitter. It remains only to place a board and a magnet in the case. The design flaw is a low volume, so when fishing, the signaling device will have to be kept as close to you as possible. Another solution to the problem is to add to the schema audio frequency amplifier. It will be easiest to assemble a single-stage bipolar transistor amplifier, but you can create a more complex design. A good result will be the use amplifier chips, for example, TDA2003 - its price is less than 30 rubles. An 8 ohm speaker and an additional power supply must be connected to the amplifier.

Sensors

Energy of sun

A very reasonable solution would be backup power electronic bite alarm solar battery located on the body of the device. You can buy a solar battery, or you can, if you wish, make it yourself. High-voltage multi-chip diodes with a removed case, some types of transistors are well suited for this. But the easiest way is to connect diodes in a transparent case in series to generate the required voltage and in parallel to generate the required current. All these indicators are easy to control with an ordinary multimeter, and the manufacture of such a module will be excellent. practical exercise by soldering. The use of Soviet diodes of the D2 and D9 series is most justified in terms of price, power and ease of manufacture.

We hope our article was useful to you. Collect an electronic bite alarm and go fishing as soon as possible. Good luck with your catch!

All fishermen know how important it is to notice a bite in time and prepare for hooking. To date, the market offers a very large selection of different signaling devices and floats. But, in the event that you make a signaling device with your own hands, then you can get a very high-quality product without spending a single cent. The signaling device is made quite simply and the work, moreover, will not take much time to manufacture it.

Bite alarm. Manufacturing.

In order to start manufacturing a bite signaling device, it is necessary to prepare the following materials:
- Wire.
- Cambric (2 pcs).
- Pliers.
- Stationery knife or scissors.

It takes only 15 minutes to make a bite alarm.

So, you can get started.
First you need to take the wire, the length of which should depend on the size of the rod to which it will be attached. Approximately, you can take about 30 cm. In principle, it does not matter what material is taken for this work. If you take a strong steel wire, it will be difficult to work with it. That is why in this example the most common aluminum wire is taken, because it is soft and durable.

Now you need to take the cambric. This is necessary so that this design holds well and the fishing thread does not get stuck in the signaling device. By the way, you don’t need to buy cambrics in a store, because this is exactly the thing that you always have quite a lot on hand.

For example, you can take any cable available at home that will fit in diameter and remove part of its insulation. For this homemade product, it would be best to take a cable from a satellite or television antenna. Now you need to cut off part of the cable with scissors or cut the insulation with a clerical knife and remove it.

After the cambric is ready to use, you need to cut a large piece into two parts, because this is the number of parts you need to work.

Now we need to get back to the wire. It is necessary to bend one end of it exactly as shown in the photo below. The bent part will be attached to the rod. It is for this that one of its edges is rounded. The bottom of the wire must be left flat. It is necessary to make a bend in such a way that its edge goes to the base of the signaling device, in order to fix it all with a cambric after a while.

After the work done, it is necessary to immediately put on the existing structure two cambric.

Now you need to bend the edge of the wire on the other side, while the eye made should be directed upwards. Next, you need to bend the wire in the other direction, when compared with the first. You need to bend quite a bit, just enough to create a second ring.

So, now you can make the second ring, this time you need to make a completely rounded shape. You also need to leave a little wire that is adjacent to the base of the signaling device and secure it with a second cambric.

Next, you need to put on cambric in order to clamp both sides. So, now you can see the finished product, which you just need to attach to your rod.

For such a product, you can use a thicker wire in order to make the design even stronger and more reliable.

To fix this signaling device, you simply need to remove the cambric and attach the first bend to your rod (on the first large ring), and through the second you need to pass the fishing thread.

When the rod is folded, the signaling device will not interfere with the transportation of fishing tackle.

The positive thing about making a signaling device with your own hands is precisely the fact that no money is spent in its manufacture. At the same time, we have a really high-quality signaling device of our own production, which is enough for many fishing trips. Due to the fact that this signaling device was made of aluminum, it will not corrode and breakage.

Perhaps many fishermen are faced with the fact that plastic analogues from stores cannot withstand a long period of operation and break quickly. In the case of making a signaling device with your own hands, a lot of effort and time is not wasted, but it turns out it is much better than a store one. Such a signaling device performs well when fishing with bottom rigs. At the same time, even the smallest bite will be noticed and there will be an opportunity to respond in time.

When hooking and withdrawing fish, the signaling device will not interfere. It will also be during long-distance casting of the bait. In addition, there is no need to prepare the signaling device for casting the rod, because everything will always be ready for perfect work.

Radio circuits for beginners

V. POLOVINKIN, Zheleznogorsk, Kursk region.
Radio, 2002, No. 4

Recently, Chinese-made quartz alarm clocks, which are distinguished by a relatively high ring volume and low cost, have become widespread. If the clock is out of order, but the alarm is still working, it can be used in various amateur radio designs. For example, in the proposed bite alarm. It reacts both to a sharp bite, and to a cautious one, both to a pull inside the reservoir, and to movement towards the shore.

The operation of the signaling device is based on the interaction of magnetically controlled contacts (reed switch) with a permanent magnet. While the magnet is near the reed switch, its contacts are in one state, and when the magnet is removed, they are in another state.

The signaling device circuit is shown on rice. 1,a, and the location of the pins on the alarm clock board - on rice. 1b. When the contacts of the reed switch SF1 are open (when carrying the device), the transistors VT1, VT2 are closed, the current consumed from the power supply G1 does not exceed 1 μA - this is the consumption current of the alarm clock chip DD1. In standby mode, when the magnet is located almost above the contacts of the reed switch, they are closed, but the state of the signaling device does not change.

It is worth at least briefly moving the magnet relative to the axis of the reed switch forward or backward, as the contacts of the reed switch open. A negative pulse will be sent to the base of the transistor VT1 through the R1C1 chain. The transistor will open and capacitor C2 will be charged through it. As a result, the transistor VT2 will open and turn on the alarm sound generator, and the capacitor C2 will start to discharge through the resistor R3 and the emitter junction of the transistor VT2. The duration of the generator operation depends on the parameters of the C2R3 chain and, at the ratings indicated in the diagram, is approximately 2 s. During this time, an audible signal will sound. At the same time, an alternating voltage from output 3 of the alarm clock is supplied through the capacitor C3 to the LED HL1, and it flashes. The brightness of the flashes depends on the capacitance of the capacitor C3, unfortunately, it is small, because with an increase in the capacitance of the capacitor, the volume of the alarm sound decreases.

If you want to increase the brightness of the LED, you need to assemble the amplifying stage according to the diagram shown on rice. 2.

The reed switch can be KEM-1, KEM-2 or another with closing contacts. Transistors - any other of the series indicated in the diagram. Capacitors - KM-6 and K50-35 (SZ - in Fig. 2), resistors - MLT-0.125 or MLT-0.25. Diode - any other silicon, LED - any of the AL307 series. Magnet - from sensor burglar alarm"SMK" in a plastic case with holes for attaching fishing line. It is possible to use another permanent magnet, to which two rings are attached with EAF epoxy glue at such a distance that after passing the fishing line through them, the magnet cannot rotate around its axis.

Details are mounted on the board ( rice. 3) and attach it to the top cover of the case - a soap dish.

The LED is fixed on the cover with 88H glue or epoxy. Opposite the alarm emitter, holes are drilled in the side wall of the cover. And on top of the cover, a rectangle is drawn above the reed switch - it will allow you to accurately orient the permanent magnet. While fishing, the rod, signaling device and permanent magnet are placed as shown in rice. 4.

In the absence of the specified alarm clock, the signaling device can be made on transistors ( rice. 5).

The input stage remains the same, but the capacitor C2 is used with a much larger capacitance. From it, the voltage is supplied to a multivibrator made on transistors VT2, VT3. The repetition rate of its pulses is about 2000 Hz. From the collector of the transistor VT2, the pulses are fed through the capacitor C3 to the LED and light it up. The sound emitter - capsule BF1 - is included in the collector circuit of the transistor VT3, being the load of the cascade.

The capsule is best used from foreign lighters with music, the resonant frequency of which is approximately equal to the specified frequency of the multivibrator. The TEMK-3 and DEMK capsules used in telephones sound somewhat worse. You can also try to use the TK-67 capsule by rewinding its winding until a resistance of 15 ohms is obtained. In any case, to get a louder sound, you may have to more accurately set the frequency of the multivibrator by selecting resistors R4 and R5.

From the editor. It should be noted that with the selected LED switching circuit, it is impossible to increase the supply voltage above 1.5 V.

Regularly visiting the nearest reservoirs with a fishing rod and bait, I thought about how to apply the education of an electronic engineer to automate fishing. Fishing rods, fish finders, boats, baits and much more can be improved and offered to the fishing community. It was decided to start with something simple and, no doubt, useful in every workplace of silent hunting. So, in this article, you will read about how the bite alarm was developed.

Donkey fishing and bite alarms

I'll tell you in order. The principle of bottom fishing is that the bait, complete with bait, is placed in a special feeder and thrown into the water with a fishing rod, where it lies on the bottom. Floats are not used, instead an indicator is put on the fishing line - a sliver, a bell, a light bulb, etc. When a fish bites, it pulls on the line and the indicator moves. The fisherman picks up the rod and reels the line, at best, along with the fish. Sometimes the indicator is worn on a rod that oscillates when biting. The evolution of indicators began with wooden pegs fixed on a fishing line, then they were replaced by bells. A little later, devices luminous with chemical or LED light appeared. Now the market is full of Chinese devices that, when biting, produce sound and light signals simultaneously. One of the advantages of electronic alarms is that they continue to beep and flash for a while after a bite has ended, giving the fisherman a better chance of noticing it if he or she is looking away or just gaping. As a rule, indicators are placed on the rod or permanently on special pegs. The principle of operation of such devices is based on capturing vibrations of a fishing rod or movements of a fishing line. Important point: there are practically no (I have never seen) electronic devices that are directly attached to the fishing line in the same way as pegs or bells were previously attached.

Simultaneously with the evolution of indicators, there was an evolution of their mounts. It ended with the appearance of a universal suspension, worn on a fishing line, into which Chinese bells or LEDs can be inserted. My own experience and communication with fellow fishermen suggested that not everything has yet been invented and improved.

So, let's designate the living space of the proposed design: a light-sound indicator will be developed, worn directly on the fishing line or inserted into a Chinese suspension. If such things already exist, then I will not be upset, because it is simply interesting to work in this direction.

Principle of operation and choice of element base

Several constructions came to my mind that can be used as the basis of a signaling device:

• piezo alarm. The piezo element oscillates, deforms and generates voltage. This principle is used in many alarm systems, for example, automobile ones;
• movable magnet combined with a Hall sensor. The element fluctuates, the sensor picks it up, the signaling device works;
• the same, only with LED and photosensor;
• sensor with reed switch and moving magnet.

I decided to stick with the first option. A piezo element is good in that it generates voltage when it is deformed, and if voltage is applied to it, then, on the contrary, it deforms and at the same time makes a sound.

That is, it turns out a sensor and a tweeter in one bottle, an obvious savings in space and weight. It remains to choose a specific model of the tweeter. To do this, I went to the nearest radio store and bought all the available models.

Among all the variety, it was necessary to find the loudest and most sensitive squeaker that would work on battery power. It is important to note that in order for the tweeter to make sounds, it must be supplied with a voltage that oscillates at a frequency of the order of several kilohertz. To get such a voltage, I planned to use a special device “signal generator of a special form”, but it just broke down, there was also an idea to take voltage from a sound card, but in the end I decided to solder the generator on a breadboard, and immediately debug both the tweeter and the circuit as a whole . After a short search on the Internet, several variants of multivibrator and single vibrator circuits on logic integrated circuits were found, they were slightly modified and the result was a circuit containing both a single vibrator and a multivibrator. The single vibrator starts for a few seconds after receiving a signal from the piezo sensor (tweeter). While on, it supplies voltage to the multivibrator, which generates oscillations at a frequency of 1-5 kHz, and thereby causes the squeaker to make sounds. After a while, the single vibrator turns off, the circuit calms down and goes into standby mode. Such a bite alarm circuit can be assembled from fairly simple and cheap components. But, being embodied in a real device, it is difficult to change and this is its main drawback. However, the circuit board was soldered as shown in the following figure. In addition to logic elements, it also has a battery compartment and operational amplifier(AD822), which is needed to increase the signal from the piezo sensor if it is too small.

After testing various piezo sensors, the MFT-31T-2.8 element was chosen. It turned out to be the most sensitive - during oscillations with a period of 1-2 Hertz and an amplitude of 5-15 cm, a voltage of about one volt is generated. The sound it makes is also pleasing. Anyway, the sound seemed quite loud in the room. Other elements produced less voltage, on the order of several hundred millivolts. And in terms of sound level, they were slightly superior or slightly inferior.

Having decided on the piezo element, I proceeded to select other components of the device. The decision to use logical elements OR-NOT/AND-NOT as a control part bribed with its simplicity and cheapness. To be honest, I didn’t know how else to assemble a penny scheme and have even begun to prepare this one for production. But then the PIC10F220T microcontroller caught my eye. Owners of smartphones, computers and tablets will be interested to know that there are devices with the following characteristics:

This chip is ideal for a bite alarm: small size, low power consumption, necessary peripherals on board, including an ADC and a timer. All this at a price of $0.5. By changing the software, you can experiment and bring to mind the functional part, which means that the device receives the design flexibility that is so necessary for new developments. Without hesitation for a long time, I replaced the logic chips with this microcontroller. It remains the case for small - to decide on the power source. A battery with a charge circuit and a connector on the board would complicate the design too much. Just in case, I flipped through several catalogs of radio components. The widespread 2032 batteries were pleasantly pleased - a voltage of 3V with a capacity of 210 mAh. It is easy to calculate that a microcontroller that consumes 100 nA in sleep mode can use such a battery to sleep through autumn, winter and spring, in general, the entire break between fishing seasons. In working mode, she also promised to serve more than one fishing trip. The voltage level allowed the microcontroller and other structural elements to work. Given the penny cost of these batteries, it was decided to use them. In addition, suitable holders KLS5-CR2032-03 were chosen, from which the battery can be easily removed and replaced after a complete discharge. In general, the cost of components is $ 5-7. Having adopted the indicated element base, I developed a schematic diagram and turned to a familiar printed circuit board designer. After brief discussions and verbal statement of the TOR, a printed circuit board was designed and then manufactured, which is eventually used in the first prototypes.

Case design and manufacture

What the electronic device without a case and what is a prototype without a case printed on a 3d printer? In a few days, the same familiar designer developed the necessary drawings. The body consists of a base and a cover. The base contains a pin for inserting into a Chinese suspension (my know-how) and an eye for attaching to a fishing line.

At that time, I did not yet know that a transparent case could not be printed on a printer. Faced with the harsh realities of early 3D printers, the case walls had to be made thinner to allow light from the LED to shine through the ivory plastic (the only one available in the print shop). Having gained experience in the field of 3d printing, for future samples of this and other devices, a Chinese reprap prusa i3 printer was purchased with a kilogram of translucent plastic. I hope this will increase the freedom of choice in terms of cases, but at that moment I had to use the services of a third-party manufacturer.

The placement of the LED inside the case is dictated by the requirements of the waterproofness of the device. Transmission of light is provided by translucency, but what about the controls - the power button and the choice of sensitivity modes? The answer was found in Google. It turns out that in a computer keyboard under the keys there is a special silicone gasket. The first keyboard that came across was disassembled, the gasket was removed, rounds were cut out of this gasket and glued to the body to seal the buttons. The board is fastened with screws, in the same way, only with the addition of rubber gaskets, the cover and the body of the signaling device are connected.

Software

After sending the printed circuit board to production, the development phase began software. The operation algorithm is quite simple: you press the button - and the signaling device wakes up, subsequent presses change the sensitivity mode, there are four of them in total. If the signal from the ADC exceeds a certain threshold value, which means a bite, the microcontroller generates a sound signal using a piezo emitter. If the button is pressed for more than 5 seconds, the device enters sleep mode. The program came out small and simple, the only difficulty was to fit all the code into the available 256 bytes of flash memory.

Characteristics of the signaling device

In the end, the board was soldered, the program was written, and the whole device was packed into a case. It's time to give the characteristics of the signaling device:

• dimensions 43 x 35 x 18 mm;
• weight 15g;
• fastening on a fishing line or in a suspension;
• 4 sensitivity modes;
• CR2032 battery;
• time to battery discharge in operating mode is approximately 400 hours;
• time to battery discharge in sleep mode > 1 year;
• moisture protection from rain or splashes.

Tests

And then came the long-awaited moment of field testing. End of September, small pond, non-flying weather. Three donks were abandoned and brought to combat readiness three indicators. Unfortunately, not a single bite happened in a few hours, so I had to imitate them by twitching the fishing line. At the same time, it was possible to evaluate the reaction of the signaling device to bite and side roll in strong wind conditions, the audibility of sound and the visibility of light signals. The sensor showed good sensitivity with small bites, while the response was equally good with various directions line movements. However, a strong side wind rocked the device and also caused it to fire. To eliminate the effect of side roll, the sensitivity had to be lowered, lowering it to the fourth level. Of course, at the same time, the reaction to light bites worsened, but in a strong wind they are basically not noticeable. The audibility of the signal was worse than expected. So, during strong gusts of wind, the sound is practically inaudible already from a distance of two meters, although at home or on a fine day on the street it was perceived loud and sharp. It should be noted that we were in hoods.

The visibility of the LED was significantly worsened by the opaque body. At the beginning of fishing, even at dusk, the indication was noticeable, then with the sunrise I had to look closely to distinguish it. The device has two LEDs - front and rear, this was done so that the alarm was visible from any angle. After testing, I'm thinking of placing both LEDs on the side of the fisherman.

It also turned out that it is necessary to change the algorithm of the button. IN real conditions- with a strong wind and frozen hands, switching occurs with some emotional effort. Perhaps increase the chatter filter time constant or add a separate on/off button.

Results

Tests have shown that the bite alarm basically performs its functions, while some components require modification. First of all, I plan to make transparent or translucent cases, change their shape and carefully consider the junction of the base and cover for better moisture protection. A more expensive operation is to increase the volume, since this requires changing the circuit and the circuit board of the device. And, finally, the most difficult is to eliminate the sensitivity to roll.

In general, work on the indicator took two months of episodic work, or a total of one and a half weeks, not counting substantive communication with fishermen, which brings only pleasure and, of course, does not count towards the total time.

Since ancient times, people have used various ways, for effective tracking of fish bites. These were all kinds of floats, gatehouses or visual observation of the tip of the fishing rod. With time and experience came the desire and ability to improve these devices. And with the advent of new technologies, more “smart” bite alarms began to appear. Now it is different kinds nods, bells, light, mechanical and electrical bite indicators.

Electronic signaling devices

In the distant 60s, the development of electronic signaling devices began. They combined visual and audible alarms. One of the more popular bite alarms was the Heron. The main disadvantage of this device was the need to connect it to an external battery.

Development did not stand still. Contacts with wires were replaced by small sensor blocks built into the body of the signaling device. They are much more reliable and more sensitive than older models.

Modern electrical signaling devices can receive a bite signal through:

• Form

Such devices are mounted directly on any convenient location rods with sticky tape. It can be used for both summer and winter fishing. The indicator housing is made in the form of a small cylinder, weighing about 12 grams. It is sealed and does not sink. The cylinder has an on-off button and sensitivity level settings for:

1. Predatory or large white fish;
2. Small white fish;
3. Winter fishing.

There are also auto (on-off) functions of the device when hooking. To save energy, there is an option to turn off the device if there are no bites for a long time (more than three hours)

The principle of operation of such devices is to remove information from the rod blank by a sensor built into the body. False signals from the wind, disturbances of the reservoir are not recorded. The bite signal is given by sound (up to 50 m) and LED (up to 100 m).

• Lescu

These are electrical signaling devices of a traditional form. They are produced with fasteners for installation on a rod blank, or mounted on a rod pod, a rod stand. They consist of:

1. Corps;
2. signaling roller;
3. Batteries (crowns);
4. Microcircuits;
5. Sound, light signaling device.

The body is made of plastic or metal. It has a special place where the power supply is installed. In the upper part there is a roller with a photocell for fishing line. Inside the case there is a microcircuit, LEDs and a sound signal speaker. On the surface there are buttons for on-off, volume, sound tone selection, as well as a light signaling button.

The case has a threaded mount for screwing onto a stand or rod pod. The signaling device itself is also a stand for the rod. More expensive models have waterproof cases. For budget models, you can advise - to fill the board with candle wax on your own. This will prevent moisture from getting on the chip.

One of the most popular mechanical signaling devices is Megatex (picture below.)

Operating principle such signaling devices is simple:

1. The body is screwed onto the stand. It is brought to the working position (power is connected, turned on). The desired sound tone and volume are adjusted (this is convenient when fishing with several rods).
2. Tackle is thrown, a fishing rod is installed on the signaling device. The line starts up on the roller.
3. Slack is selected (swingers or mechanical bite alarms are needed to tension the fishing line), the friction on the reel is correctly set.

When biting, the fishing line through the roller sends a signal to the photocell. In turn, it generates a signal with sound and light. This informs the fisherman about the beginning of the bite.

As a rule, electrical signaling devices have 2 indicators. Red shows bite. Green or blue lights up when the device is turned on. It also burns for a few more seconds after the end of the bite. This makes it possible to see on which of the fishing rods the fish were biting.

Rating of top 3 models of electronic signaling devices

Electronic Chinese signaling device "Hoxwell" It has:

1. Light, sound indicator of inclusion;
2. Eight tone levels;
3. Volume control, mute mode;
4. Settings memory function;
5. LED bite direction scale;
6. Built-in signal transmitter;
7. Enable night mode.

These are models protected from moisture ingress, with a lateral arrangement of control buttons. The case is additionally protected by rubber pads along the seams of the joints. A battery is used for power. These models are also equipped with pagers.

Electronic signaling devices with pagers

Modern professional signaling devices are equipped with built-in signal transmitters. This is convenient for day or night fishing, being at a relatively large distance from the rods. The bite signal is transmitted to the pager. The signal transmission distance reaches 200 m. The pager can notify the fisherman with a vibro, sound or light signal. Each set of signaling devices has its own pager. It can simultaneously receive signals from 4 devices.

Advantages of using models with a built-in signal transmitter:

1. Obtaining information about the tension of the fishing line, at a distance from the place of fishing.
2. On which of the rods did the bite occur?

The pager is configured together with signaling devices, which allows you to select and control the signal. It is necessary to remember about the timely charging of the device, so as not to be left without communication with signaling devices during fishing.

Ready-made sets of signaling devices

Such sets are equipped with a pager, usually 4 signaling devices, batteries and chargers (if necessary). The set is packed in a plastic case. The signaling devices are equipped with built-in transmitters for communication with the pager.

They also have special connectors for connecting electronic swingers. They have waterproof cases. These kits are easy to transport, easy to assemble and use. Ready-made sets of signaling devices have a rather high cost. However, they differ in the quality of the models and in practice, the absence of fakes.

Light signaling devices (firefly)

For night fishing, one of the most common types of signaling devices are fireflies. They are easy to use, affordable and suitable for all types of fishing (bottom, float or spinning).

Basically, signaling devices manufactured by the manufacturer have the following forms:

• In the form of a nail or stick;
• In the form of a light bulb, which increases the area of ​​​​illumination.

According to the principle of operation, such devices are divided into three types:

1. Collapsible capsules with small batteries and LED. Such fireflies are reusable, thanks to the replacement of batteries.
2. Light-accumulative signaling devices. The principle of their operation is the accumulation of light during their short-term illumination. For their work, you need to have a good flashlight.
3. Disposable chemical fireflies. They consist of a plastic flask with component A. Inside of which there is a capsule with reagent B. Under mechanical action, components A and B are mixed, and a reaction occurs - luminescence.

Light signaling devices can be of different colors. For chemical species, the most popular is the yellow-green glow. It's pretty bright color. He is calm enough not to irritate the eyes. There are also light and sound bite alarms. They will be discussed below.

Fireflies are attached:

• On the float, inserting into their silicone antennas. Or with the help of elastic bands - on their tops.
• To the tip of the rod, using silicone rubber bands. Special plastic fasteners are also sold. Several fireflies can be installed in such mounts.

The main brands that you can buy in a fishing store: Ocean Sun, Kostal, Balzer, Salmo, Rodinson, Liman Fish, Strike Alert.

Do-it-yourself light signaling device

As mentioned above, light signaling devices have proven themselves well for night fishing. In order not to buy them in the store, you can easily make such an indicator at home. For manufacturing you will need:

1. Straws for a cocktail;
2. Crocodile clips;
3. Glue gun;
4. LEDs;
5. Round flat batteries 3 V;
6. Heat shrink, according to the size of the battery.

A piece of straw, 3–4 cm long, is filled with a glue gun. An LED is inserted inside. Its legs protrude by 0.5 cm. A battery is inserted into the heat shrink tube, 2 cm long. A piece of straw with a fixed hairpin is inserted into one end of the heat shrink. Fits tightly with a lighter. A straw with an LED is inserted into the other end. The legs of the LED are located on different sides of the battery (+, -). Sets down so that it can be pulled out.

Such homemade device enough for the whole fishing season. Manufacturing does not take much time, does not require soldering and high costs.

Audible alarms

1. Bells on a clothespin;
2. Rattles;
3. Bells.

Such indicators are used on bottom gear at night. Sound alarms are also installed during daylight hours, when it is difficult to visually monitor big amount with Anastasia. They are usually mounted on a fishing line or donkey rod tip. (Pictures enlarge.)

Very often, the factory fasteners of the bell are difficult to reset during cutting from the fishing line. This interferes with the normal reeling of tackle when fighting. Therefore, you can modify the signaling device holder yourself. For this you will need:

1. Thin-walled rubber hose, approximately 3 cm in diameter.
2. A small bolt with a nut that will fit into the ear of the bell

A ring is cut off from the hose, 1.5 cm wide. An incision is made on the ring and a hook is shaped. A hole must be made in its long part. Through it, the bell is attached to the elastic with a bolt.

You can make your own bell. For example, from decorations, on the backs of old iron beds. They look like a cylinder with conical tops.

For manufacturing you will need:

1. Saw the cylinder in half;
2. Make a hole in the upper part;
3. Attach a nut to the self-tapping screw, tying it on a fishing line. This will be the tongue of the bell;
4. Self-tapping screw, screwed into the hole from the inside of the bell;
5. A wine cork is put on the tip. An incision is made in the cork for attaching the indicator to the fishing line of the rod.

You can make a bell out of an old phone call. We disassemble the call, we get two cups. In the upper part, through the hole, the tongue is fixed. For it, you can use the nut on the fishing line. To install the signaling device on the fishing line, you can use a cork.

Do-it-yourself bells differ from factory fixtures in their special sound. This allows you not to confuse their sound on a fishing trip with their neighbors.

How to increase the catch of fish?

For 7 years of active passion for fishing, I have found dozens of ways to improve the bite. Here are the most effective ones:

1. Biting activator. This pheromone additive lures fish the most in cold and warm water. .
2. Raise gear sensitivity. Read the appropriate manuals for the particular type of tackle.
3. Lures based pheromones.

Mechanical signaling device

Mechanical signaling devices play the role of visual control over the bite. One of the simplest can be a piece of clay or dough, suspended on a fishing line or an ordinary part of a branch found on the shore.

Purchased mechanical signaling devices can be divided into three types:

• "Monkey". This is a fairly simple design of a rod and a tube (cylinder). The tube is put on the fishing line between the reel and the first ring. The rod is stuck into the ground at an angle or vertically. A signaling device is hung on it. When biting, he moves freely along the line. Such a signaling device can be made with your own hands, using foil instead of a tube.
• Bad (hanger)- This is a load fixed on a chain or flexible cable with a clip for fishing line. At the other end is a stand mount. This is a fairly sensitive type of alarm. Works well in calm weather. Hangers are much lighter than classic swingers.
• swinger- is one of the most popular (especially among carp anglers) mechanical types of signaling devices. The principle of their work is to raise, lower the device on the fishing line. There are several options for sale:
• Classical is a swinger, consisting of a weight of 100 grams, which moves freely along a metal lever. One end of the lever is equipped with a hinge for attaching to the stand. At the other end is a plastic head with a special clip for fishing line.

It is installed as follows: after casting, the rod is placed on a stand; excess fishing line is reeled; the fishing line is wound into the mount on the head; the desired sag is regulated by the movement of the load along the lever; when hooking, the line comes out freely from the clamp on the head.

Classic swingers are mainly used in combination with electronic signaling devices.

A lightweight swinger consists of a plastic tube with a wire rod inside. At the front end is a bright head with a fishing line attachment. At the other end there is a loop for installing a signaling device on the rod throughput ring. It works in the same way as the classic swinger. Only constantly is on the form. The price of this model is much lower.

Another of the mechanical signaling devices is a nod. It's very easy to make it yourself. To do this, in any fishing store you can buy a spring nod for a winter fishing rod. This spring has a whip attachment and a bright ball on the end. To put a nod on the bottom gear you need:

1. Cut the rubber mount near the hole through which it is put on the whip
2. Put it on the tip of the rod near the first ring
3. To secure, a thread is wrapped around the fastening circle and tied. Top with insulation
4. The fishing line is passed through a ring, a spring with a ball

The gear is ready to go. The sensitivity of the nod is adjusted by the movement of the spring. This design allows you to see even the lightest bites. It is good to use for gear with a hard blank tip.

Side bite alarm for feeder

At its core, the feeder itself is a rather sensitive tackle. However, sometimes this is not enough with strong winds and large breaking waves. Also, on reservoirs where it is not possible to put the feeder parallel to the shore, the visibility of bites decreases. For such conditions, a side signaling device or a side jib tip will be indispensable.

Finding a ready-made design in stores is quite problematic. Here are some tips on how to make such a device yourself:

Details for the signaling device: attachment to the rod; metal rod; steel wire.

1. Fasteners can be made from a conventional plastic clamp for PVC pipes. A rubber ring will help to fix it on the rod.
2. The tube or rod is selected according to the diameter of the hole in the clamp.
3. Steel wire with a diameter of about 1 mm and a length of up to 20 cm is bent in an arc. One end is bent at an angle of 90º. The length of the bend is approximately 5 cm. It is attached to the rod with glue and threads. At the second end, a hook is made for fishing line. To better see the bites, colored cambrics are put on the wire.
4. The whole structure is attached in front of the first winding ring closer to the coil.

Take the usual shop nod for a winter fishing rod, insulating tape. Installation method:

1. There is an elastic band on the nod for putting it on a fishing rod. With the help of electrical tape, it is mounted on the form next to the coil.
2. A cut is made on the nod ring, into which the fishing line will be wound.
3. A nod is installed in the groove on the elastic band, a fishing line is started. The signaling device is ready for operation.

These simple and sensitive adaptations respond well to even sluggish bites from inactive fish.

Bite alarm for ice fishing for girders

Zherlitsy are designed for catching predatory fish on live bait. Gutter devices:

1. Base;
2. Reel with fishing line;
3. Rack with a signaling device.

For a bite signaling device, a flag is most often used. This is a piece of bright matter (usually red) on a narrow, thin plate 40 - 60 cm long. Sometimes springs are placed. The operation of this indicator is very simple. When setting up, the flag, in a bent position, is fixed on the coil. The predator, taking the bait, pulls the line. Scrolling, the coil releases the flag. It straightens up, which allows you to see the bite.

A little advice. To distinguish your flags from other people's gear, it is better to make the signaling device of the original shape and color.

From all of the above, we can conclude that regardless of the conditions and methods of fishing, signaling devices play an important role in successful fishing. The angler himself can choose which model suits him. Buy signaling devices in the store or make them yourself, with your own hands, how to improve your gear.
