For an NPN open emitter output, the collector is connected to the positive voltage rail, so the emitter outputs a high voltage when the transistor is on and is hi-Z when off. For a PNP open emitter output, the collector is connected to the low voltage supply, so the emitter outputs a low voltage when the transistor is on and is hi-Z when off.
Tynker is an educational programming platform, like Scratch, to help children learn coding skills, including game design, web design, animation and robotics. It includes courses in Minecraft Modding, Minecraft Game Design, Creative Coding, Python and CSS.
The game was developed open-source on GitHub with an own open-source game engine [22] by several The Battle for Wesnoth developers and released in July 2010 for several platforms. The game was for purchase on the MacOS' app store, [ 23 ] [ 24 ] iPhone App Store [ 25 ] and BlackBerry App World [ 26 ] as the game assets were kept proprietary.
The transistor continuously monitors V diff and adjusts its emitter voltage to equal V in minus the mostly constant V BE (approximately one diode forward voltage drop) by passing the collector current through the emitter resistor R E. As a result, the output voltage follows the input voltage variations from V BE up to V +; hence the name ...

A common variation omits the collector resistor of the output transistor, making an open-collector output. This allows the designer to fabricate wired logic by connecting the open-collector outputs of several logic gates together and providing a single external pull-up resistor. If any of the logic gates becomes logic low (transistor conducting ...
Donald Trump’s return to power is creating a reality television-like competition for attention among a group of black-robed candidates – some of whom may hope to one day wind up on the Supreme ...
