Build a Metal Detectors CCO schematic Wiring diagram

This is a schematic of a simple metal detector that uses technology CCO, by Coil Coupled Operation. Thomas Scarborough designed this new incarnation of the metal detector, a new genre that he invented in 2004. This is the first project of the Internet and can be built easily.

200W Subwoofer Amplifier Circuit

Circuit Description

Here is a circuit that uses a mosfet amplifier amplicable for subwoofer as the main booster, or the basis of this boosterAmplifier. Circuit which uses MOSFET Power Amplifier is powered by the output more than 200W Speaker 8 Ohm impedance. We also include a suitable power supply circuit with the use of MOSFETamplifier with 200W of power, not only of his course Schematic diagram for the layout design is also already there.

Rolling Shutter Motor Control

Rolling Shutter Motor Control Circuit. An electrically operated rolling shutter usually has a standard control panel with a three-position switch: up, down and stop. If you would like to automate the opening and closing with a time controlled switch, a few additional wires will have to be connected. Typically, the controls are implemented as indicated in the schematic ‘Normal Situation’. If this is indeed the case, then you can see in ‘New Situation’ how the shutter can be automated with a timer. There is only one method to determine the actual schematic of your control schema, and that is to open the control box and using an ohmmeter, pencil and paper to check out and draw the schema. Make sure you turn the power off ﬁrst though! Connect a 230-V relay (with both the contacts and the coil rated 230 VAC) to the timer.

Rolling Shutter Motor Control Circuit

The changeover switch between automatic and manual control needs to be rated 230 VAC as well and may not be a hazard for the user. The relay and switch are preferably fitted in a plastic mains adapter enclosure with built-in plug, which is plugged into the timer. It is a good idea to check first if this will actually ﬁt. Because of the manual/automatic-switch, the operation is completely fail-safe and misunderstandings are out of the question. The switch prevents the issue of conflicting commands (with disastrous consequences) when, for example, the shutter is being automatically raised and manually lowered at the same time.

Power amplifier for FM radio receiver

Schematic is suitable for use in radio tuner or FM radio receiver when it is assembled and ready for use. Where if the low gear power radio receiver, with the aid of power amplifier is less powerfull voice / hard to better and just right. For use hios speakers , use a low-power , because power amplifier has only the power output of 2 X 5 Watt stereo power amplifeir with impedance of 4 Ohm. Working on a minimum voltage of 4.5 Volts and maximum of 16Volt. Use the correct voltage supply - really have been filtered out in order to improve the performance of these power amplifiers.

24 W BTL or 2 x 12 W stereo car radio power amplifier

GENERAL DESCRIPTION

The TDA1510AQ is a class-B integrated output amplifier encapsulated in a 13-lead single in-line (SlL) plastic power package. Developed primarily for car radio application, the device can also be used to drive low impedance loads (down to 1,6 Ω). With a supply voltage (VP) of 14,4 V, an output power of 24 W can be delivered into a 4 Ω Bridge Tied Load (BTL), or when used as a stereo amplifier, 2 × 12 W into 2 Ω or 2 × 7 W into 4 Ω.

Features

Flexibility − stereo as well as mono BTL
Low offset voltage at the output (important for BTL)
Load dump protection
A.C. short-circuit-safe to ground
Low number, small sized external components
Internal limiting of bandwidth for high frequencies
High output power
Large useable gain variation
Good ripple rejection
Thermal protection
Low stand-by current possibility
High reliability.

500W Low Cost 12V to 220V Inverter Wiring diagram Schematic

Attention: This Circuit is using high voltage that is lethal. Please take appropriate precautions

Using this schema you can convert the 12V dc in to the 220V Ac. In this schema 4047 is use to generate the square wave of 50hz and amplify the current and then amplify the voltage by using the step transformer.

How to calculate transformer rating
The basic formula is P=VI and between input output of the transformer we have Power input = Power output

For example if we want a 220W output at 220V then we need 1A at the output. Then at the input we must have at least 18.3V at 12V because: 12V*18.3 = 220v*1

So you have to wind the step up transformer 12v to 220v but input winding must be capable to bear 20A.

Electronic12Vdc Mobile Battery Charger Wiring diagram Schematic

Electronic12Vdc Mobile Battery Charger Circuit Diagram provides up to 20 V output from a 12-V automotive supply, to enable constant current charging of Nicad battery assemblies up to about 18 V total. VI forms a square-wave oscillator, Dl and D2, coupling this square wave to the 12-V battery supply to obtain over 20 Vdc. If this is not needed, SI is left open. Ql forms a current regulator to determine the charging rate of the rechargeable battery. R4 is selected from the table or it can be switched with a rotary selector switch.
