A man playing a version of the wire loop game. A wire loop game, or buzz wire, is a game which involves guiding a metal loop (a 'probe') along a serpentine length of wire without touching the loop to the wire. [1]
Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
A buzzer or beeper is an audio signaling device, [1] which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices , timers , train and confirmation of user input such as a mouse click or keystroke.
A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and ...
In 2016 Paweł Zadrożniak improved his previous version of the Floppotron with 64 floppy drives, 8 hard drives, and two flatbed scanners. Every column of 8 FDDs was connected to one 8-channel controller built on ATMega16 microcontroller; the HD was controlled by 2 push-pull outputs built with discrete SMD MOSFETs.
A joy buzzer (also called a hand buzzer) is a practical joke device that consists of a coiled mainspring inside a disc worn in the palm of the hand. When the wearer shakes hands with another person, a button on the disc releases the spring, which rapidly unwinds creating a vibration that mimics an electric shock to the unsuspecting victim.
Rather, it is a set of instructions – for example, for pitch or tempo – and can use a thousand times less disk space than the equivalent recorded audio. [52] [53] Due to their tiny filesize, fan-made MIDI arrangements became an attractive way to share music online, before the advent of broadband internet access and multi-gigabyte hard ...
A metal kazoo Other examples of kazoos. The kazoo is a musical instrument that adds a "buzzing" timbral quality to a player's voice when the player vocalizes into it. It is a type of mirliton (which itself is a membranophone), one of a class of instruments which modifies its player's voice by way of a vibrating membrane of goldbeater's skin or material with similar characteristics.
