Can you plug 120v into your car? If you want to power a laptop or other large electric device in your car, you need an inverter that turns your car’s 12-volt DC power into 120 volts of AC like you … Continue reading →

For a quick and simple dual power supply, use two resistors in series connected in parallel with two capacitors. Connect the two ends to the battery or power source and BAM! You have a dual power supply. What is dual … Continue reading →

An Adapter pattern acts as a connector between two incompatible interfaces that otherwise cannot be connected directly. An Adapter wraps an existing class with a new interface so that it becomes compatible with the client’s interface. What is an adapter … Continue reading →

Adaptors are a form of nonverbal communication—a class of gestures and movements that help people deal with discomfort, such as stress, anxiety and any other unsettling thoughts. What is an example of an Adaptor? An adaptor is a body motion … Continue reading →

After each diode, the voltage can be seen to drop by 0.6 volts. In this way, diodes can be used to reduce voltage, in a circuit. Zener diodes allow electricity to flow through them, in the same way as normal … Continue reading →

Connecting 24V to 12V LED Strips The most straightforward way to force a 12V LED strip to work in a 24V system is to split a 12V LED strip into two identical 12V LED strip segments and connect the copper … Continue reading →

Balancing resistors can help with this. To reduce the voltage down to 6, there’s a number of possibilities, depending upon how precise the voltage needs to be. Voltage regulator(s) are the way to go here. Adjustable regulators that provide 6V … Continue reading →

Powering your home TV from the 12-volt lighter socket in your car, truck or RV is possible. Since the home TV uses AC (alternating current) power and the vehicle produces DC (direct current) power which is stored in the battery, … Continue reading →

A laptop doesn’t have a power supply inside the case that converts power. Instead, it has an AC adapter that works same as power supply does and it provides the power to the laptop. Which power supply is best for … Continue reading →

If you were to run a 12v motor off a 24v battery the stall current could then be excessive if it weren’t limited by the controller. Therefore, provided you chose a controller suitable for the motor you use, you can … Continue reading →

The cigarette lighter socket still continues to be present on most modern cars for attaching various equipments like mobile, laptop chargers, vacuum cleaners, compressors for inflating tires and the like in addition to a 5V USB socket too. When did … Continue reading →

What is a 1.5v Battery? A classic nominal voltage, most AA, AAA, C, & D cells are 1.5 volts, and many household and handheld devices have been built to use that voltage. The first zinc-carbon dry cells naturally produced 1.5 … Continue reading →

To learn how to set up a TV at a tailgate, the good news is you have plenty of options, such as: Hotspot a Smart TV. Digital TV Antenna (simplest method) Satellite dish (DISH Network or DIRECTV) Screen mirroring (worst … Continue reading →

A buck converter (step-down converter) is a DC-to-DC power converter which steps down voltage (while drawing less average current) from its input (supply) to its output (load). Why buck converter is step down? A buck converter, also known as a … Continue reading →

The positive lead on most chargers is either colored red or has red on the connecting end. The negative lead is often colored black and/or has black coloring near the connecting end. How can you tell if a battery charger … Continue reading →
