A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which generates energy via a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator/dynamo , supplying electric current to an incandescent bulb or light-emitting diode .
These flashlights may be designed to be impact resistant, weatherproof, and to float. [4] [5] Other models include features such as a solar cell phone charger, [6] an AM/FM radio, or a siren to call for help in an emergency. Some models include a hand crank dynamo for charging at night. [7]
A flashlight or electric torch (Commonwealth English), usually shortened to torch, is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb , but these have been displaced by light-emitting diodes (LEDs) since the early 2000s.
That’s not an issue for pocket flashlights. If you need one often, a flashlight isn’t much good if you can’t keep it nearby and easily accessible. That’s not an issue for pocket flashlights.
A photograph showing two Fulton MX-991/U Flashlights, next to an unofficial reproduction and a standard angle-head flashlight. The MX-991/U Flashlight (aka GI Flashlight, Army flashlight, or Moonbeam [1]) from the TL-122 military flashlight series of 1937-1944 and is a development of the MX-99/U flashlight issued in 1963 [clarification needed].
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
The bad came on the extra point, when the Texans got a hand on Cameron Dicker's kick and sent it flying straight up in the air. Dicker was in perfect position to get the ball as it came down and ...
It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage.
