Solar Cell Based Camera Flash Trigger Circuit
Photography flash units need correct timing. However, many old flash units do not have trigger input, so a Solar Cell Based Camera Flash Trigger Circuit is useful. This circuit is very simple as it uses very few components and also it does not need any battery. The circuit works using light only and when a […]
12V Boost Converter Circuit from 3.3V to 5V Supply
Nowadays, many electronic projects need higher voltage. However, the available supply is very low for example 3V or 3.3V batteries are common. But many circuits need 12V so, here we have designed a 12V Boost Converter Circuit from 3.3V to 5V Supply. This circuit increases low DC voltage to high DC voltage and therefore, it […]
Boost Converter Circuit From 5V to 12V using Transistors
Many electronic projects need 12V power, but sometimes only 5V supply is available, for example from USB, logic board or microcontroller. So, here this Boost Converter Circuit From 5V to 12V using Transistors is useful which converts 5V DC to 12V DC. It uses simple components like transistors and inductor, it is with low cost […]
Simple 12V Power Supply Circuit with Filter Capacitor
Today, many electronic circuits need DC power, but main supply is AC power, so we must change AC to DC. Therefore, this Simple 12V Power Supply Circuit with Filter Capacitor is needed, as this circuit gives 12V DC output and current capacity is up to 2A. This circuit is very simple, easy to make, cost […]
5V High Current Buck Converter Circuit using IC MC34063
Today, many electronic circuits need stable 5V supply. However, input voltage is not always fixed, sometimes it is 12V and sometimes it can go up to 30V. Therefore, a buck converter is needed. This 5V High Current Buck Converter Circuit using IC MC34063 reduces voltage efficiently and it also saves power. Here, we used the […]
