Power Supply Circuits

Have anyone tried using a toy which needs 3.3V but charger gives only 5V? That too much power! This article for How to Convert 5V to 3.3V Circuit is like small helper. It take strong 5V and make it weak 3.3V which is right for device. This help when USB or charger give more power […]

To change 3V to 5V we need to use a boost converter. This Simple Boost Converter Circuit from 3V to 5V take low voltage and make it higher. It takes 3V from battery and give 5V to run our devices. Circuit Working: Parts List: Category Component Quantity Resistors (All resistors are 1/4 watt unless specified) […]

If we have 1.5V AA battery but gadget need 10V to work. Then this 1.5V To 10V Boost Converter Circuit is small power maker. It changes 1.5V weak power to strong 10V. This circuit is useful for devices which need more power than what battery gives. Circuit Working: Parts List: Category Component Quantity Resistors (All […]

If our device need right DC power to work safe then this Simple DC High Low Voltage Cut Off Circuit work like a guard. If battery is too low then circuit stop power to save our device. If battery is too high then also circuit stops power to protect. This circuit keep device safe from […]

If anyone’s project needs How to Generate a Safe 220V AC Supply from home power, then this is the circuit but we need to be careful. This voltage is dangerous. To stay safe we can use a step-down transformer. It makes voltage lower and safer. It also has safety parts to stop electric shocks. Circuit […]

Simple Low Power Ozone Generator Circuit use less power. It make ozone gas from air. It uses electric spark to change oxygen to ozone. Ozone help clean air and water and also kills the germs. But too much ozone is also not safe, it can be bad. Circuit Working: Parts List: Category Item Quantity Capacitors […]
