Make sure to match the polarity of the power source with the strip’s input. Method 4: Using a Power Bank When you’re on the go or in a situation where you don’t have access to a traditional power source, a power bank can come in handy for connecting your LED light strip. Power...
This two tone siren circuit explained here gives out a continuously varying high amplitude sound. Since the supply voltage is not critical, it can be used in cars, motor cycles or at home. It can replace the ordinary call bell. A dual one siren is an amplified alarm circuit designed to g...
A relay transistor driver circuit can be considered a great example of a boost converter circuit. The flyback diode connected across the relay is introduced to short circuit the reverse back EMFs from the relay coil and to protect the transistor whenever it switches OFF. If this diode is remov...
The chip is wired by leads (19) to terminal pins (blue) by which it can be connected into a circuit. But the really important parts are two soft iron "flux concentrators" (orange, 15, 21), which make the device very much more sensitive. When you place a magnet (22) near the ...
When either the heating or cooling activates, the auxiliary devices (fan, pump, etc) need to all turn on, with a fixed polarity. However, the TEC needs to have its polarity reversed between heating and cooling, so it can pump the heat in the correct direction. I have a circuit with th...
4. Include a title block in the footer of the page The page title block is present in the footer of the schematic page. It is a good practice to fill in all the required details such as page size, update date, revision, document number, name/function of the circuit, and company discl...
A circuit breaker is an incredibly simple tool used to control the flow of power to a household or business. Construction Photography/Avalon/Getty Images The circuit breaker is an essential device in the modern world and one of the most important safety mechanisms in your home. Whenever ...
How to replace the battery. - Shaving and Grooming If the operating instructions for a model contains a procedure for removing the built in storage battery, please note that this is for the recycling/disposal of the storage battery and is not intended as an explanation of disassembly for repair...
This circuit remains broken until you put something conductive, like solder, in contact with both halves of the tip. The solder completes the circuit, also allowing current to pass through a second light. Because of electrical resistance, both the solder and the tip heat up very quickly, and...
Power Transformer Definition: A power transformer is defined as a static electrical device that transfers electrical energy from one circuit to another using electromagnetic induction. Types of Power Transformers: There are core-type, shell-type, dry-type, and liquid-filled transformers, each designed...
