Series Connected Voltage Boost Circuit for a Battery Operated LED Lantern Using Atmega

Photo. This is the test circuit -the basic driver is only two transistors, two resistors, the circuit was evaluated using a white LED, but when it was time to button it up and archive it, I replaced the expensive white LED with a cheap green one. Othere LED Driver Circuits on this site: White LED …

White LED Battery Powered Power Failure Light Using Atmega

Overview Where I live most of the time, the AC power drops out upon occasion. This used to leave me groping around in the dark for a flashlight. I could have bought a battery-backed up “emergency light” for about US$35, but being basically metal boxes with floodlights attached, they would make my living room look …

Timekeeping test circuit

Real Time Clock/Calendar/Alarm with Interpreter for battery backed-up and battery powered operation with DS interface using ATtiny12

Based on the Atmel ATtiny12L-4PI microcontroller -A real Time Clock/Calendar for less than US$1.50 in moderate quantity. This is the timekeeping test circuit. It includes a one-transistor circuit to switch in the 5V power supply when present and drop back to the 3v battery the rest of the time. That loop of blue wire-wrapping wire …

Grid Intertie Inverter

Solar Power / Panel Inverter – Grid-Intertie Inverter using Attiny45

For the last year I’ve been working on a prototype for a Solar Inverter that can be Grid Intertied. A solar inverter takes the 12V DC (or other voltages) from the solar panels and converts it to 120V AC which is the power that most of your household appliances use. A Grid-Intertied inverter allows you …

Micro-controller Programming on a Bread Board Using Atmega

In playing around with DIY electronics, Pugs has developed enough confidence to share his knowledge with his juniors. So, in one such occasion, he decided to give a try to program a micro-controller, as part of the electronics hobby club. There have been many hobbyist micro-controllers, like 8051, PIC, AVR, … and an equivalent or …
