12V to 110V Converter The meaning here is the 110V converter to convert 12V DC voltage from the battery into 110V or 220V AC. Let us call this the DC to AC inverter. Why is that, because the term converter is usually devoted to a type of voltage conversion, for example, from AC to AC through a transformer, or DC [...]
Build an DC Adaptor using 110V Transformer Speaking of transformers often take you for a little understanding about the voltage (V) and current (I) of electricity. A transformer is very closely related to two components. Simply put this has provided information to you regarding the power (P = in Watt) that is owned by the transformer, i.e. by multiplying the [...]
DC Laptop Computer PSU Circuit Operate your laptop from a car can be done easily if you have a DC to DC Converter, namely a power supply device for changing a DC voltage into another DC voltage is greater (step-up) or smaller (step-down). Changes in output voltage is usually followed by changes that accompany the current. This Step-up DC-DC converter [...]
Basic Photocell Sensor Circuit What is a photocell sensor? Photocell sensor can be regarded as a transducer that is used to detect the light intensity. At full intensity beam with a photocell resistance could be worth about 10 Ohm and the low intensity light (in darkness) could be worth several hundred Ohm. A photocell sensor resistance value varies between the [...]
Wireless Infrared Alarm Circuit An infrared alarm is an alarm that works via infrared. Infrared is used as a sensor, from an infrared transmitter to the receiver. When infrared lights are blocked by people who passing through it, the alarm will activate a buzzer. This infrared alarm is suitable for use in a corridor or small gate to detect people [...]
