This is a circuit diagram for a solid state charge detector. It can detect very weak electric fields. The circuit has three components: a 6-volt battery, a light-emitting diode (LED), and a field-effect IC ADM666A..
This is a slight modification of that circuit. In the previous circuit you have to keep the switch pressed for making the IC play the full music. Here if once the push button is pressed C1 is charged and the transistor Q2 will keep the IC playing the music....
The main part of this doorbell circuit are two NE555 timer ICs. When some one presses switch S1 momentarily, the loud speaker sounds a bell tone as long as the time period of the monostable multivibrator built around IC1...
MAX2659 low-noise amplifier (LNA) is designed for GPS, Galileo, and GLONASS applications. Designed in Maxim`s advanced SiGe process, the device achieves a 20. 5dB gain and an ultra-low-noise figure of 0. 8dB while maximizing the input-referred 1dB....
Equipment designed to detect changes associated with fire, monitor the integrity of their operations and provide automatic control, the transmission of information necessary to prepare the facility for fire, temperature, light based on a predetermined....
A common topology for DC-AC power converter circuits uses a pair of transistors to switch DC current through the center-tapped winding of a step-up transformer Examine these checkplot images from a PCB drafting program, for a control board based on this....

The circuit uses two LDRs which are placed one after another (separated by a distance of say half a metre) so that they may separately sense a person going into the room or coming out of the room. Outputs of the two LDR sensors, after processing, are used in....
This is necessary to set the 10K potentiometer while pointing the device at your TV to block the IR rays from the remote. This can be done by trial and error..
The Electronics Schematic Diagram MJR7-Mk3 Mosfet MJR6 page includes distortion extracted using the nulling method with a speaker load and a music signal to demonstrate that these designs have no audible distortion in normal use. The MJR7 has even lower....
The first section of the 555 timer is wires as an astable oscillator with R2 and C1 setting the frequency. The output is available at pin 5. The second section is wired as a phase inverter. That output is available at pin 9. Resistor R3 and R4 keep output....
The mixer circuit below has 2 line inputs and 2 mic inputs, 2 line outputs. The mic inputs are suitable for low impedance 200-1000R dynamic, simple mixer was designed for three dynamic microphones...
This small FM transmitter with a range of about 50 meters designed for hoby. With lots of mini-transmitters then you have a comprehensive, action-packed radio program. Due to the power supply via the USB port of a high frequency stability is achieved.....
How many speaker attach with this amplifier and what is the what is the speaker Ohom and watt valu of this speaker plz ans me my email Sir, you made this amp and reallly properlly works this amp to used life time. Which transfarmer used for 2 channals .....
