The DC 3V-30V 3-Wire Digital Voltmeter with Red LED Display is a compact and versatile voltage measuring device. This digital voltmeter is designed to measure DC voltages in the range of 3V to 30V. It's suitable for a variety of low- to moderate-voltage applications. The voltmeter features a three-wire connection, commonly consisting of power (VCC), ground (GND), and the voltage to be measured (IN). The three-wire configuration simplifies the wiring process. The voltmeter is equipped with a bright red LED display that provides a clear and easily readable indication of the measured voltage. Red LEDs are commonly used for visibility and readability. The voltmeter is designed to be compact, making it appropriate for programs where the area is confined. Its small form factor permits clean integration into various initiatives and devices. The voltmeter can perform at a wide voltage range, making it versatile for use in special digital circuits and initiatives.

Different sound systems and where to use them

Studio Monitors : These sound systems are commonly found in recording studios, filmmaking, television, radio studios, and television studios.

Home Stereo Sound Systems: These sound systems are normally found in modern automobiles.

In-Wall/Ceiling Speakers :  in-ceiling or in-wall speakers Soundbars are typically installed in the ceilings of homes and can contain multiple speakers in a single enclosure.

Outdoor Speakers : Outdoor speakers are normally placed outside the home as they are waterproof to resist humidity.

PA System: PA stands for public address, and it is used to broadcast a loud sound to a large audience. It can be found in sports stadiums, facilities, and public transport vehicles.

Bookshelf Speakers : portable for small rooms, there are active and passive bookshelf speakers, normally lasting up to 10 years.

The Benefits of Renting a Sound System

Budget solution : device cost and its maintenance cost are something that bothers you when you want a budget solution, then taking a sound system on rent can be your best choice. 

Flexibility : You can try a variety of sound systems for a particular duration and decide which one is most suitable for you. And if something is not working for you, you can easily return it and choose a new one. 

Technology variation : When you take sound systems on rent, you can actually use the latest technology and a variety of brands. You can simply try out sound systems before making an actual purchase. 

A projector, or image projector, is an optical device that creates an image (or moving images) on a surface using a lens on a projection screen. Projectors are used for a variety of purposes besides watching movies, like playing games on a big screen, creating murals on walls, spending quality time with your children, cooking, redecorating your home, or even projecting artwork on walls. But when it comes to choosing the right projector for your needs, people often get confused.

Types of projectors: DLP, LCD, or Liquid-Crystal on Silicon (LCoS) are three major types of projectors.

DLP (Digital Light Processing) -  DLP projectors have more mirrors, and thus more pixels to project your desired images and videos in high definition and 3D. DLP projectors are of two types: single-chip and three-chip versions. Single-chip versions start at under $1,000, while three-chip models start at around $10,000.

LCD- LCD projectors tend to be less expensive. The images are sharp and focused, making the projector great for movies, particularly in larger environments. However, they also require more maintenance and upkeep, particularly with changing out filters and preventing dust buildup. The LCD projectors are common amongst business meetings, seminars, workshops but LCD can fail fast and replacements are very expensive. 

LCoS- LCoS stands for Liquid Crystal Technology on Silicon. It is a hybrid between DLP and LCD. So far, the lightest projector made with LCoS technology to date weighs 12 lbs. So these projectors are neither portable, nor compact.
