![]() ![]() The voltage V EE provides a positive potential at the emitter which repels the holes in the P-type material and these holes cross the emitter-base junction, to reach the base region. The operation of a PNP transistor can be explained by having a look at the following figure, in which emitter-base junction is forward biased and collector-base junction is reverse biased. The direction of current indicated in the circuits above, also called as the Conventional Current, is the movement of hole current which is opposite to the electron current. A small forward bias is sufficient at the emitter junction whereas a high reverse bias has to be applied at the collector junction. The collector base junction is reverse biased and its resistance is a bit higher. The N-type material is provided positive supply and P-type material is given negative supply to make the circuit Reverse bias.īy applying the power, the emitter base junction is always forward biased as the emitter resistance is very small. The N-type material is provided negative supply and P-type material is given positive supply to make the circuit Forward bias. The figure below shows how a transistor is biased.īy having a look at the above figure, it is understood that The function of both the PN junctions is controlled by providing bias to the circuit through some dc supply. As one junction is between the emitter and base, that is called as Emitter-Base junction and likewise, the other is Collector-Base junction.īiasing is controlling the operation of the circuit by providing power supply. Transistor BiasingĪs we know that a transistor is a combination of two diodes, we have two junctions here. We have so far discussed the constructional details of a transistor, but to understand the operation of a transistor, first we need to know about the biasing. The following figure shows how different practical transistors look like. The PNP and NPN transistors can be differentiated using a Multimeter. In a Practical transistor, there is a notch present near the emitter lead for identification. Hence the terminals are always to be kept in mind while using a transistor. Due to the specific functions of emitter and collector, they are not interchangeable. As the collector of a transistor has to dissipate much greater power, it is made large. The arrow-head in the above figures indicated the emitter of a transistor. ![]() The symbols of PNP and NPN transistors are as shown below. This is a bit larger in size than emitter and base. Its name implies its function of collecting the carriers. The right side material in the above figure can be understood as a Collector. Its main function is to pass the majority carriers from the emitter to the collector. The middle material in the above figure is the Base. This is simply indicated with the letter E. either electrons or holes.Īs this emits electrons, it is called as an Emitter. This has a moderate size and is heavily doped as its main function is to supply a number of majority carriers, i.e. The left hand side of the above shown structure can be understood as Emitter. They have their functionality as discussed below. The three terminals drawn from the transistor indicate Emitter, Base and Collector terminals. The construction of transistors is as shown in the following figure which explains the idea discussed above. They are PNP and NPN which means an N-type material between two Ptypes and the other is a P-type material between two N-types respectively. ![]() This type of connection offers two types of transistors. Three terminals are drawn out of the three semiconductor materials present in it. The Transistor is a three terminal solid state device which is formed by connecting two diodes back to back. ![]() It also regulates the incoming current and voltage of the signals. A transistor also acts as a switch to choose between available options. Amplification is needed wherever the signal strength has to be increased. Amplification means increasing the signal strength. Now if this signal is read as it is, you cannot get a fair output. The received signal will obviously be weak due to the disturbances it would face during its journey. Suppose that you have a FM receiver which grabs the signal you want. A Transistor is a three terminal semiconductor device that regulates current or voltage flow and acts as a switch or gate for signals. After having a good knowledge on the working of the diode, which is a single PN junction, let us try to connect two PN junctions which make a new component called Transistor. ![]()

The flying is done similarly by rolling and pitching the ship and the weapons and other upgrades and items are the same as in the original(s). Other than these graphical upgrades, the game resembles the original. Still, the graphics hold onto the retro feel of Elite and you will not see well-rounded 3D spaceships in this game - rather they are still relatively blocky and textures close to the old style. Similarly, the original wireframe vector graphics have been replaced with textured 3D models. Thus, as you roll and pitch your ship around, the framerate no longer drops to around 3fps, as in the C-64 version. For a fan effort, it has progressed pretty quickly from basic flight simulation into a fully playable game and the PC port came out of Alpha to Beta in March this year and is now keeping up with development on the Mac version.īeing a fan-made remake of Elite, Oolite offers much the same gameplay as the original game, but naturally brings it up-to-date with modern technology. Oolite is an entirely independent interpretation and expansion of the original game. That is, until Giles Williams from Aegidian first released Oolite for Mac in 2004. It was only one of many projects that held up hopes, but ended up discarded because of various reasons. Those who have followed the discussion threads know about Elite: The New Kind that promised a lot, but was eventually discontinued and withdrawn from the Internet. With the lack of a true successor to the original title, some fans started their own pet projects to bring the game to the modern computer. If this game is unknown to you, I urge you to take a look at our Elite Retroview (in Features) before reading this preview. Even the official sequels, while they held on to the core of Elite, expanded it in ways that made them essentially different games. Many games since have attempted to capture the same atmosphere and playability that the original Elite had, but none, or almost none, have succeeded. Marcan did not waste time but turned his ship quickly towards the next enemy.Įlite is a game, the name of which makes many old gamers sigh and remember the numerous days and weeks that they spent playing it late into the night, living the alternate life of a commander of a small spaceship. ![]() The laser beam sheared the space around the first pirate Krait until at last it found its mark and the small ship exploded in a brilliant flash. Marcan waited for a few more seconds before squeezing the trigger of his own weapons. He knew that by the time the enemy was close enough to actually hit him, their weapons would already be too hot to continue firing. And in the darkness between the stars, an old enemy lurks, fearless, perhaps waiting for order to collapse entirely.The pirate Kraits fired first, impatiently, and as the beam lasers shot past Commander Marcan Wolfwood's Cobra Mk III, he smiled to himself ruefully. ![]() The mercenaries they hire for a few credits a kill are too few, too unreliable to do so either. The Cooperative's police force, concentrated near a few influential planets, can no longer maintain order. The trade ships that once safely travelled between planets now have to be well armed and escorted to fend off pirate attacks, from small-time criminals desperate for their next meal, to powerful robber barons extracting tithes from everyone who passes through their space. The two thousand star systems of the Cooperative once enjoyed a golden age of peace and prosperity, and perhaps the wealthiest of them can still pretend to. ![]() Perhaps one day, everyone might know your name. You've got a ship, some weapons, and enough spare cash to get started - and one day, you might get the fame, wealth or glory you want. Among the seven trillion people who are - at least officially - Cooperative citizens, you are nobody. ![]() ![]() ![]() Just because a News Feed and instant messaging are useful for work doesn’t mean you want your boss seeing how you socialize. It’s the reason that Facebook does not directly integrate your normal social network profile with Workplace, opting to keep them completely separate. For example, you might only share Excel or your web browser, but not Slack or your email client.Įstablishing this level of privacy for screen sharing is important since that’s one of the biggest concerns of clients using office software made by Facebook. That could be invaluable if you want to avoid embarrassing yourself or exposing sensitive work data or communications. Not only can you share your full-screen, but you can select to only share a specific desktop app you’re running. Screen sharing is now available on both the Workplace Chat desktop apps and on web. While Slack only added screen sharing in May over four years after launch, Workplace now has it less than a year after its debut. As Facebook evolves from text towards visual communication, being able to show people what you’re looking at could be an important complement to video chat. What’s totally new to Facebook is screen sharing. Now that it has 1.3 billion monthly users, though, it could potentially explore desktop software to keep growing. The Messenger team has been largely focused on mobile rather than desktop or even web features. Since then, several convincing but fake third-party desktop apps have proliferated. Workplace Chat is one of Facebook’s only pieces of desktop software besides its casual gaming platform Facebook Gameroom. Facebook tried offering a Messenger for Windows app in 2012 before shutting it down in 2014. You can also set up desktop notifications that ride over your other windows so you never miss a message. It provides a big dashboard of all your conversations, text search, and the typical photo, video, voice clip, emoji, GIF, and web cam sharing. The desktop app works similarly to Workplace Chat’s dedicated website, which in turn is modeled after. The desktop app is still in beta and being tested by Workplace customers who are providing feedback that we’ll use to improve the product before a wider rollout.” Workplace by Facebook spokesperson Vanessa Chan confirmed the launch of the desktop app to TechCrunch, saying “This was one of the most widely requested features by customers, so we built it. It makes it easy to message with co-workers throughout the day without relying on a browser tab that can get lost amongst all your other tabs. ![]() It’s clear that Facebook is applying its rapid development style in an bid to conquer offices with an all-in-one collaboration app while competitors only offer a piece of the puzzle.įacebook bursts back into desktop softwareīuried in the help section of Workplace, TechCrunch spotted a download link for the beta version of the Workplace Chat desktop app for both PC and Mac. Screensharing could help Workplace attract more clients and disrupt the clunky screen sharing of enterprise apps like Skype and WebEx. Workplace has over 14,000 businesses on board paying $1 to $3 per user, and recently signed up Wal-Mart. ![]() But users would surely enjoy if the consumer Messenger app got its own desktop app and screen sharing options one day. ![]() Right now, they’re only available for Workplace, Facebook’s enterprise collaboration software that competes with Slack and other business apps. TechCrunch has discovered that Facebook has stealthily launched official desktop PC and Mac chat apps with screen sharing - two features users have been begging for. ![]() ![]() ![]() ![]() Here below, you will find an interactive mindmap and a set of comparative tables and mini-reviews to make your evaluation as simple as possible. To help you select and identify the best wireframing solution for your specific needs, I have then compared and selected a number of tools (both web-based and software applications). In fact, here you will find a selection of website prototyping tools that cost under $150 per month (well below in most cases).

Spicy things like my squirrel repellent above. You can also grind up some chili pepper flakes and spread them around the base of the plants.You may think of raccoons as cute, furry little animals but they’re actually quite the nuisance! Before they get in – deter raccoons to save you grief (and cost) later! They will enter your yard and home seeking food, shelter and water and if they find any, they are quite hard to get rid of. This remedy can get a bit expensive if you use it for the entire garden though.ĭecoys - Buy fake cat silhouettes or fox decoys to stake out in the garden to scare them off. The reflection from the tin foil scares off squirrels and they won't like stepping on the foil. ![]() Tin Foil - Put a layer of tin foil around the base of plants and in flower pots. Netting - Surround your plants with netting, similar to what you would do to keep birds from eating berries.Ĭhicken Wire - Create a tent of chicken wire around smaller plants or enclose the whole garden area in chicken wire.Ĭover The Ground - Putting gravel in the beds (similar to what you would use in a gravel driveway) may deter them as they won't enjoy walking on it.
