DC-to-DC converter Basics

DC-to-DC converter
A DC-to-DC converter is a device that accepts a DC input voltage and produces a DC output voltage. Typically the output produced is at a different voltage level than the input. In addition, DC-to-DC converters are used to provide noise isolation, power bus regulation, etc.[more]

Triac light control

Triac light control
The triac lighting-control circuit in Figure 1 is small and inexpensive because load and housekeeping power come directly from the line voltage, thereby eliminating bulky, expensive supplies. The CLZD010 closed-loop controller maintains constant light intensity by automatically adjusting the timing of the triac’s firing until the feedback signal and setpoint command are equal.[more]

PIC18F458 based Solar Recorder

Solar Recorder
The device used for measuring daily insolation has been developed. The device was built with a PIC18F458 and the 128MB Multimedia Memory Card, MMC. The solar radiation is measured by a calculator solar cell. The PIC chip interfaces the MMC using SPI mode. The interval between samples is set to one minute. The firmware detects the memory card, assignes the file name and begins recording automatically. The LCD displays the file name, current sample and real-time ADC data. [more]

DC motor speed controller

DC motor speed controller
This is the circuit which inputs the control voltage which was created by the turning of the motor in PIC. The input voltage to PIC is converted by A/D converter. Changed voltage is used for the PWM function of the CCP to control the motor drive. At the circuit this time, a small motor is used as the generator to detect the number of rotations of the motor. The input voltage (the control voltage) to PIC is changed by the fluctuation of the number of rotations of the motor. [more]

Electronic Speed Controller for brushed DC motors(ESC)

Electronic Speed Controller
This is a very basic speed controller, and is still in its infancy. It lacks sophistication, is very easily manipulated by EMFs, has a few quarks, but it proves the theory and gets the job done. You have to start somewhere.In this website include very well documented DIY tutorial on how to build a basic electronic speed controller.[more]
