Electronic tonleck warning device with their own hands
The device that I designed is distinguished by compactness, sensitivity, simplicity in the manufacture, weighs less than 400 grams, is activated after throwing gear in just a few seconds (Fig. 1).
Fig. 1. General type of gear with electronic alarm: 1 - rod; 2 - coil; 3 - bandwidth rings; 4 - Punching alert; 5 - Stand for the rod; 6 - auxiliary fishing line for a biplate signaling device; 7 - clip; 8 - the main fishing line.
An alarm can be used at any time of the day, a wave and wind to him also no interference. It works in the "sound" and "light" mode - it is convenient if fishing goes to a few nearby bottom fishing rods, each of which is equipped with an individual alarm. At the same time, no connection wires are needed, additional plug connectors, plugs, etc. It comes to the siren (buzzer) - there is a bite, and on which rod - will tell the light signal.
Fig. 2. Electrical diagram of the Bleklevka alarm: V1 - transistor MP-26B; V2 - transistor MP-37B; R is a 300-680 resistor; TLF - telephone capsule TK-67; L - signal light 35 V and 0.36 A; S - Gerson Kem-1; E - magnet; B - Power Battery CBS 4.5 V; T - toggle switch.
The body of the alarm is a plastic box with a size of 92 x 30 x 144 millimeters, all its items are freely placed in it. In the lid need to drill holes for better sound permeability. The electrical circuit is shown in Fig. 2. Capset of the TK-67 headphone can be replaced with DEM-4M, DMS, DAMSH-2. His constant current resistance should not exceed 250 ohms. Instead of Herkeon Cam-6, you can use KEM-1.
The Klev sensor in the device consists of a hermetic contact (Hercon) S, glued to the spring plate (you can cut out of a visor for shaped cap), and a magnet E (a piece of core from a small-sized dynamics). The stretch of spring plate under the armor is wrapped with a thin tape, and the reserves are attached to the plate with threads (Fig. 3).

Fig. 3. Plate with Herke: 1 - ring; 2 and 4 - winding from threads; 3 - conclusions of Herkeon; 5 - Gerson; 6 - insulating tape; 7 - spring plate; 8 - corner for mounting the plate; 9 - screws; 10-hole for attaching a corner with a plate to the alarm body.
Fig. 4. Plate with magnet: 1 - tin plate; 2 - magnet; 3 - insulating tape or thread winding; 4 - slot under the fastening screw.
It is important to find a place for a magnet correctly. To do this, it is primed to a thin iron plate with threads or thin tape, and on the other end they make a slot to the fastening screw (Fig. 4). After installing the spring plate with a reservoir in the alarm case, move the magnet along the side of the box and determine this position at which the Gercon works. This can be determined by the light bulb or the zoomer from the headphone cap, if the device is already mounted.
On the spring plate above the Herkeon, the ring is attached with threads, and in front of it in the side wall of the box, the hole is drilled through which the segment of the auxiliary fishing line with a diameter of 0.4 millimeters is passed. One of her end is tied to a ring, and the other - to the clips (you can take a clothespin), which is connected on fishing to the main fishing line. When the clip is littered, it is freely removed and the device does not interfere with the retractation of the fish.
When bippying, the main fishing line is stretched, the power of the pogs is transmitted to the spring plate with the reversion, which turns out to be in the magnet action zone; The inclusion of the generator circuit occurs, the siren (buzzer) is distributed, the signal light is turned on. Instead of incandescent lamp, any LED can be applied, but in sunny weather its glow is minor.
Fig. 5. Exemplary location of the signalizer parts in the case: 1 - toggle switch; 2 - signal light; 3 - telephone caps; 4 - Power Battery; 5 - corner for fastening the spring plate; 6 - card with radio components; 7 - Bracket with holes for fastening the alarm to the rod stand; 8 - the main fishing line; 9 - ring; 10-spring plate; 11 - Geron; 12 - Plate with a magnet.
When laying the alarm (Fig. 5), the gercon and a plate with a magnet should be put closer to each other, then the gercon will be easier to work. So that when transporting the alarm is not turned on spontaneously, the packagle is put on the housing. The stand for a rod can serve as part of a ski stick, cutting tube from clamshells, etc. The two holes for fastening the alarm are drilled in it.
