  3. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...

  4. Arduino - Wikipedia

    en.wikipedia.org/wiki/Arduino

    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.

  5. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    Aircraft often use 400 Hz power internally, so 50 Hz or 60 Hz to 400 Hz frequency conversion is needed for use in the ground power unit used to power the airplane while it is on the ground. Conversely, internal 400 Hz internal power may be converted to 50 Hz or 60 Hz for convenience power outlets available to passengers during flight.

  6. Alkali-metal thermal to electric converter - Wikipedia

    en.wikipedia.org/wiki/Alkali-metal_thermal_to...

    The overall system could achieve as high as 14 W/kg with present collector technology and future AMTEC conversion efficiencies. [ citation needed ] The energy storage system has the potential to batteries, and the temperatures at which the system operates allows long life and reduced radiator size (heat-reject temperature of 600 K).

  7. Frequency changer - Wikipedia

    en.wikipedia.org/wiki/Frequency_changer

    Frequency changers are used for converting bulk AC power from one frequency to another, when two adjacent power grids operate at different utility frequency.. A variable-frequency drive (VFD) is a type of frequency changer used for speed control of AC motors such as used for pumps and fans.

  8. ATmega328 - Wikipedia

    en.wikipedia.org/wiki/ATmega328

    ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.

  9. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    The typical efficiency of TEGs is around 5–8%, although it can be higher. Older devices used bimetallic junctions and were bulky. More recent devices use highly doped semiconductors made from bismuth telluride (Bi 2 Te 3), lead telluride (PbTe), [10] calcium manganese oxide (Ca 2 Mn 3 O 8), [11] [12] or combinations thereof, [13] depending on application temperature.
