Schema modifications

Assembling the metal detector with your hands (diagram shown below), you need to remember that the main elements of the device are a damper on the microcontroller, a capacitor and a pen holder. The control unit in the device consists of a set of resistors. Some modifications are made to drive the modulators, which operate at a frequency of 35 Hz. The Desk is made directly with narrow and broad plates of the disc shape.

Instructions for the simple Assembly of the model

Build a metal detector with his hands is quite simple. First and foremost, it is recommended to prepare the pipe and to attach to her pen. To install the control unit will need a resistor of high conductivity. Operating frequency of the device depends on many factors. If we consider modifications to the diode capacitor, they have high sensitivity.

Working frequency of detectors is about 30 Hz. The maximum detection distance of the object from them is 25 mm. Work modification capable batteries lithium type. The microcontroller for the Assembly will be required with the polar filter. Many models are on the sensors open. It is also worth noting that experts do not recommend the use of filters of high sensitivity. They greatly reduce the accuracy of detection of metal objects.

Model Pirate

To Make a metal detector "Pirate" your own hands can only be based on a wired controller. However, in the first place to build is procured by the microprocessor. To mount it you will need a blowtorch. Many experts recommend the use of grid condensers with a capacity of 5 pF. The conductivity they must be maintained at 45 MK. After the installation of the capacitors, you are ready to solder the control unit. The rack must be durable and withstand the weight of the plate. For model 4 In not recommended to use plates with a diameter greater than 5.5 cm. system LEDs do not have to install. After fastening the unit will only have to install the batteries.

Using reflex transistors

To Do with the reflex-effect transistors the metal detector with his hands is quite simple. First and foremost, experts recommend to do the installation of the microcontroller. Capacitors in this case, suitable channel type, and the conductivity they must not exceed 55 microns. At 5 volts they have a resistance of about 35 Ohms. Resistors mods are used mostly contact type. They have negative polarity and do well with electromagnetic oscillations. It is also worth noting that in the Assembly it is allowed to use lithium batteries. The maximum width of the plate for the modification is equal to 5.5 cm.

Model with convection transistors: experts ' comments

Build a metal detector with his hands only on the basis of the collector controller. The capacitors are used at 30 MK. If you believe the experts, it is better not to use high powered resistors. In this case, the maximum capacity of the elements shall be 40 pF. After the installation of the controller should have control.

These metal detectors are getting good reviews for reliable protection from wave interference. With this purpose, two filters are used the diode type. Modifications to the display systems are very rare among self-made modifications. It is also worth noting that the power supply must operate at low voltage. Thus, the battery will last a long time.

Using chromatic resistors

How to make a metal detector with his hands? Model chromatic resistors to build fairly simple, but keep in mind that the capacitors for the modifications you are allowed to apply only for fuses. Experts also point to the incompatibility of resistors with continuous filters. Prior to Assembly, it is important to prepare for model tube that is the handle. Then installed the unit. Better to pick up enchanted to 4 microns, which operate at a frequency of 50 Hz. They have a small coefficient of dispersion and high measurement accuracy. It is also worth noting that the seekers of this class will be able to work successfully in high humidity conditions.

Model with pulse Zener diode Assembly, reviews

Devices with pulse Zener diodes are distinguished by high conductivity. If you believe the experts, the improvised modifications are able to work with objects of different sizes. If we talk about the parameters, the accuracy of detection of them is equal to about 89 %. Begin Assembly of the device is from the stock rack. Then mounted to the model.

The Next step is set the control unit.Then mounted controller which is powered by lithium batteries. After the installation you can do the soldering of the capacitors. Negative resistance from them should not exceed 45 Ohms. Expert reviews indicate that modifications of this type can be produced without filters. However, it should be borne in mind that the model will have serious problems with wave interference. This will suffer the condenser. In the end, the battery models of this type quickly.

Application of low frequency transceiver

The low-frequency transceivers models significantly reduce the accuracy of the instruments. However, it should be noted that the modification of this type is able to work successfully with objects of small size. The small parameter of self-discharge. To assemble the modification of their hands, it is recommended to use a wired controller. Transmitter is primarily used on the diodes. Thus, the conductivity is provided by at around 45 µm with a sensitivity of 3 mV.

Some experts recommend to install net filters that enhance the security models. To raise the conductivity of the used modules only transitional. The main disadvantages of such devices is considered to be a blown controller. If such damage is difficult to repair the metal detector with his hands.

Using a high-frequency transceiver

High-frequency transceivers to build a simple metal detector with his hands only on the basis of the transition controller. Before you install the standard stand is harvested under the plate. The conductivity controller is equal to the average of 40 MK. Many experts are not used in the Assembly of the contactors. They have a high heat loss, and they are ways to operate at the frequency of 50 Hz. It is also worth noting that to build a metal detector uses a lithium battery that recharges the control unit. Directly sensor of modifications is established through the condenser, whose capacity should not exceed 4 pF.

Model with longitudinal resonator

In the market frequently device with longitudinal resonators. They stand out among its competitors is the high detection accuracy of objects, and thus can operate at high humidity. To self-assemble model of the harvested stand, and the plate should be applied with a minimum diameter of 300 mm.

It is Also worth noting that the Assembly of the device will need to contact the controller, and one extender. Filters are used only for mesh lining. Many experts recommend installing a diode capacitors that operate at a voltage of 14 V. In the first place they are little drain your battery. It is also worth noting that they have a good conductivity in comparison with field analogues.

The Use of selective filters

To Make a deep metal detector with his hands not just. The main problem is that in the device you cannot install a conventional capacitor. Also worth noting is that the plate for the modification is selected with a size from 25 cm In some cases, stands are installed with extender. Many experts advise to start the Assembly with the installation of the control unit. He must work at a frequency not exceeding 50 Hz. In this case the conductivity depends on the controller that is used in the equipment.

Quite often picked up by surface to enhance safety and security modifications. However, such models often overheat and are not able to work with high precision. To solve this problem it is recommended to use the conventional adapter, which is installed under the condenser units. Coil for metal detector with his hands is made from a block of transceiver.

Contactors

The Contactors in the device are installed together with the control units. Stand for modifications, use a small length, and the plates are selected at 20 and 30 cm, Some experts say that the device is to collect on the pulse adapter. The capacitors you can use low-capacitance.

It is Also worth noting that after the installation of the control unit is to solder a filter that can operate at a voltage of 15 V. In this case, the model will be maintained conductivity at 13 MK. Transceivers are most often used on the adapter. Before switching the detector on the contactor check the level of the negative resistance. The specified parameter is equal to the average of 45 Ohms.
