1000 Volt DC to DC Regulator Circuit Input voltage from high voltage DC DC converter is 12V AC at 800mA current and then converted to DC through a bridge rectifier Diode 1A. The voltage output of converter circuit can be adjusted in the range of 0-1000V DC. This high voltage DC DC converter uses the [...]
Time Interval Relay Circuit for the clock circuit above This is a programmable clock timer circuit that uses individual LEDs to indicate hours and minutes. 12 LEDs can be arranged in a circle to represent the 12 hours of a clock face and an additional 12 LEDs can be arranged in an outer circle to [...]
This project demonstrates the use of 16×1 line LCD module to interface with Nitron 16-pin MCU, 68HC908QY4. The original idea came from one evening I went out with my son to the park near my home in Korat. The park has a nice walking way for people to exercise. I was wondering how long the [...]
NE555 Electronic Buzzer Schematic This accessible cyberbanking buzzer ambit congenital based on timer works for accepting the frequency. The IC timer NE 555 acclimated as astable multivibrator operating at about 1kHz and produces a complete back switched on. The complete abundance can be adapted by capricious the 10K resistor. You may change the 10K resistor [...]
This circuit is describes about sensing air flow using microcontroller PIC16C781. In this circuit is using Programmable Switch Mode Controllers (PSMC) that combination between the Integrated Operational Amplifier, Digital-to-Analog Converter (DAC), and gated timer to construct a thermally operated air flow sensor with minimum external components. This is the figure of the circuit. Air flow [...]
This 12V inverter is very easy to build, cheap components that many electronics hobbyists may even already have. Though it is possible to build a more powerful circuit, the complexity caused by the very heavy currents to be handled on the low-voltage side leads to circuits. The circuit diagram of 12v inverter is easy to [...]
Here’s a simple home alarm circuit is for those who are eager to know the concept of home security system. It consists of three 555 timers gets the input from a contact that could be connected to a motion detector or any momentary contact that monitors a certain process. Once the contact is momentarily closed, [...]
