Previously, “White LED Lights with Caravan” written in white LED lamp designs that can be used also for interior lighting of the car. The LEDs used in the LED lamp project are easy to install but they do not light very much because they are low power. .. This LED lighting project is also used…
SMPS Soldering Station Circuit However, this voltage is linear increasing tendency due to the existence of the magnetizing current of the main transformer and due to the limited inductance of the inverter output choke. By comparing this actual current flow (pin 3 UC3845) with the setpoint setpoint (pin 1 UC 3845) is directly generated PWM…
Electronic Active Crossover Circuit Subwoofer Crossover NE5532 The audible band is in the frequency range 20 Hz to 20 kHz. Signal loud speakers are used, but they are not capable of transferring the entire audible band. Speakers are also used broadband that transmits most of the band but not whole. They still have a problem…
The most important part is the construction of a functional sample of a Arduino Uno software-defined one transmitter. After agreement with the supervisor and current options, she was elected concept with SI4713 digital circuit for FM band 76-108 MHz. first the point of practical implementation is a block design with the necessary description of the…
The game console is made up of an Atmel ATmega32 processor, comprising 32kB Flash program memory, 1kB EEPROM memory and 2kB SRAM memory. Next is the console consisting of an LCD display and a speaker. To the console for ease of maneuverability games joins the joystick. This is a 64×128 pixel LCD. Available under different…
Motor Control Circuit design and regeneration of a three – phase inverter for supplying an asynchronous motor. The inverter is designed to drive a rack drill with approx up to 1 kW. The device will be constructed using integrated circuits. Single-purpose integrated Circuits simplify the design and manufacture of low-cost applications. And thanks to that…
For a long time I was going to share with you the materials on assembling a transistor amplifier with unipolar power, assembled in retro-topology, which is still of interest to some radio amateurs. At the forum Diyaudio this ULF can be found under the name APEXAX6. This circuit does not need DC Protect, because the…
Low frequency TDA8954 class D power amplifier circuit frequency crossover circuit and digital signal procesor (DSP) complete 2-way active speaker system, simulation schematics pcb desing and Speakers solidworks Speakers coreldraw autocad desing low – frequency amplifiers in Class D and their use in active bi-amp speaker systems. It also deals with it by means of…
UC3843D STEP-UP for supplying of notebook in car. Introduction presents dividing of switching power supplies followed by a choice and a proposal of power supply. In this work we can find the specific proposal of inductor, the proposal of electronic connexion and the proposal of PCB layout. In the last part of work there are…
Li-ion 14.4V Battery Pack UC3844 SMPS Charger the UC3844 integrated circuit is supplied directly from the DC link via the resistor R2. After the circuit switches on, the power transistor Q1 is powered by the auxiliary winding. The RCD cell, consisting of R3, capacitor C3 and diode D1, protects the power transistor from positive overflows…
