Technology Connections
Technology Connections is an American YouTube channel covering the history and mechanics of consumer electronics, home appliances, and other pieces of technology, created by Alec Watson of Chicago, Illinois. Subjects of focus include transportation, HVAC, refrigeration, photography, and home audio and video, among others. The channel, which has received praise for Watson's humor and the depth and insight of his research, has amassed a large following on YouTube. Channel Watson registered the Technology Connections channel on YouTube in November 2014, with his first video, exploring Alexander Graham Bell's role in the history of sound reproduction, uploaded in September 2015. In the years since, Watson has released videos on Technology Connections covering other aspects of consumer audiovisual technology—home audio and video in particular—releasing a five-part documentary miniseries on the Compact Disc audio format by Sony and Philips in 2018; and the Capacitance Electronic Dis ...

YouTube
YouTube is an American social media and online video sharing platform owned by Google. YouTube was founded on February 14, 2005, by Steve Chen, Chad Hurley, and Jawed Karim who were three former employees of PayPal. Headquartered in San Bruno, California, it is the second-most-visited website in the world, after Google Search. In January 2024, YouTube had more than 2.7billion monthly active users, who collectively watched more than one billion hours of videos every day. , videos were being uploaded to the platform at a rate of more than 500 hours of content per minute, and , there were approximately 14.8billion videos in total. On November 13, 2006, YouTube was purchased by Google for $1.65 billion (equivalent to $ billion in ). Google expanded YouTube's business model of generating revenue from advertisements alone, to offering paid content such as movies and exclusive content produced by and for YouTube.

Telephony
Telephony ( ) is the field of technology involving the development, application, and deployment of telecommunications services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone. Telephony is commonly referred to as the construction or operation of telephones and telephonic systems and as a system of telecommunications in which telephonic equipment is employed in the transmission of speech or other sound between points, with or without the use of wires. The term is also used frequently to refer to computer hardware, software, and computer network systems, that perform functions traditionally performed by telephone equipment. In this context the technology is specifically referred to as Internet telephony, or voice over Internet Protocol (VoIP). Overview The first telephones were connected directly in pairs: each user had a separate telephone wire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-speed Camera
A high-speed camera is a device capable of capturing moving images with exposures of less than second or frame rates in excess of 250 frames per second. It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion. Early high-speed cameras used photographic film to record the high-speed events, but have been superseded by entirely electronic devices using an image sensor (e.g. a charge-coupled device (CCD) or a MOS active pixel sensor (APS)), typically recording over 1 000 frames per second onto DRAM, to be played back slowly to study the motion for scientific study of transient phenomena. Overview A high-speed camera can be classified as: # A high-speed film camera which records to film, # A high-speed video camera which records to electronic memory, # A high-speed framing camera which records images on multiple image planes or multiple locations on the same im ...

Flash Bulb
A flash is a device used in photography that produces a brief burst of light (lasting around of a second) at a color temperature of about 5500 K to help illuminate a scene. The main purpose of a flash is to illuminate a dark scene. Other uses are capturing quickly moving objects or changing the quality of light. ''Flash'' refers either to the flash of light itself or to the electronic flash unit discharging the light. Most current flash units are electronic, having evolved from single-use flashbulbs and flammable powders. Modern cameras often activate flash units automatically. Flash units are commonly built directly into a camera. Some cameras allow separate flash units to be mounted via a standardized accessory mount bracket (a ''hot shoe''). In professional studio equipment, flashes may be large, standalone units, or studio strobes, powered by special battery packs or connected to mains power. They are either synchronized with the camera using a flash synchronization cabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
