A workable all-transistor radio was demonstrated in August 1953 at the Düsseldorf Radio Fair by the German firm Intermetall. Texas Instruments had demonstrated all-transistor AM (amplitude modulation) radios as early as May 25, 1954, but their performance was well below that of equivalent vacuum tube models. There are many claimants to the title of the first company to produce practical transistor radios, often incorrectly attributed to Sony (originally Tokyo Telecommunications Engineering Corporation). The scientific team at Bell Laboratories responsible for the solid-state amplifier included William Shockley, Walter Houser Brattain, and John Bardeen After obtaining patent protection, the company held a news conference on June 30, 1948, at which a prototype transistor radio was demonstrated. Vacuum tubes were also inefficient and fragile compared to transistors and had a limited lifetime.īell Laboratories demonstrated the first transistor on December 23, 1947. The need for a low voltage high current source to power the filaments of the tubes and high voltage for the anode potential typically required two batteries. Although portable vacuum tube radios were produced, they were typically bulky and heavy. A transistor is a semiconductor device that amplifies and acts as an electronic switch.īackground A seven-transistor Soviet Orljonok radio with the back open, showing parts.īefore the transistor was invented, radios used vacuum tubes. Beginning around 1980, however, cheap AM transistor radios were superseded initially by the boombox and the Sony Walkman, and later on by digitally-based devices with higher audio quality such as portable CD players, personal audio players, MP3 players and (eventually) by smartphones, many of which contain FM radios. The pocket size of transistor radios sparked a change in popular music listening habits, allowing people to listen to music anywhere they went. ![]() ![]() Billions of transistor radios are estimated to have been sold worldwide between the 1950s and 2012. ![]() Transistor radios are still commonly used as car radios. The mass-market success of the smaller and cheaper Sony TR-63, released in 1957, led to the transistor radio becoming the most popular electronic communication device of the 1960s and 1970s. Following the invention of the transistor in 1947-which revolutionized the field of consumer electronics by introducing small but powerful, convenient hand-held devices-the Regency TR-1 was released in 1954 becoming the first commercial transistor radio.

With our creative ideas for better storage, you'll appreciate your laundry room again-no matter how small it is.

The only class we needed to use in this case was. The selectors above get us pretty close to everything we would need for now. There's many more selectors for for doing various tasks, like selecting certain child elements, specific links, etc., that you can look up when needed. No need to do nested selectors when using ids. ids, such as, are unique so you can usually use the id selector by itself to get the right element.The space tells the selector that the class after the space is a child of the class before the space. example gets an element with class example nested inside of a parent element with class temp, E.g. temp a gets an anchor element nested inside of a parent element with class temp, E.g. temp.example gets an element with both classes temp and example, E.g. #temp gets an element with an id of temp, E.g.temp gets an element with a class of temp, E.g. select_one('a') gets an anchor/link element, select_one('body') gets the body element To get a tag, such as, , use the naked name for the tag. ![]() ![]() Both of these methods use CSS selectors to find elements, so if you're rusty on how CSS selectors work here's a quick refresher: To find elements and data inside our HTML we'll be using select_one, which returns a single element, and select, which returns a list of elements (even if only one item exists). Sometimes there will be a disallow all pages followed by allowed pages like this: Many times you'll see a * next to Allow or Disallow which means you are either allowed or not allowed to scrape everything on the site. On the other hand, we are disallowed from scraping anything from the /scripts/subfolder. In this example we're allowed to request anything in the /pages/subfolder which means anything that starts with /pages/. The Crawl-delay tells us the number of seconds to wait before requests, so in this example we need to wait 10 seconds before making another request.Īllow gives us specific URLs we're allowed to request with bots, and vice versa for Disallow. A * means that the following rules apply to all bots (that's us). We don't really need to provide a User-agent when scraping, so User-agent: * is what we would follow. Common bots are googlebot, bingbot, and applebot, all of which you can probably guess the purpose and origin of. Some robots.txt will have many User-agents with different rules. The User-agent field is the name of the bot and the rules that follow are what the bot should follow. Since this article is available as a Jupyter notebook, you will see how it works if you choose that format. If I'm just doing some quick tests, I'll usually start out in a Jupyter notebook because you can request a web page in one cell and have that web page available to every cell below it without making a new request. We don't want to be making a request every time our parsing or other logic doesn't work out, so we need to parse only after we've saved the page locally. Every time we scrape a website we want to attempt to make only one request per page. With this in mind, we want to be very careful with how we program scrapers to avoid crashing sites and causing damage. With a Python script that can execute thousands of requests a second if coded incorrectly, you could end up costing the website owner a lot of money and possibly bring down their site (see Denial-of-service attack (DoS)). Every time you load a web page you're making a request to a server, and when you're just a human with a browser there's not a lot of damage you can do.

Get the desired look by clicking on the Effect Panel your Mask and tweak the values. Though not always, you may have to expand the mask while feathering because when a mask is feathered, the overall inward mask area can be shrinked.Īdjusting mask can be in two ways – Expansion and Feathering.Īcross all the Adobe tools, Opacity works similarly that changes the cropped images opacity with the addition of the mask. So, before feathering, you may try expansion. Next, the Expansion mask moves or expands the individual vertex, inward, or outward when it is already lined up. The dotted line around the mask represents feathering that blends the soft edges of the mask with the rest of the clip. Using the handles, click and drag the point and create the curved edges. One-click on the vertex point creates a corner point which gives a sharp angle to your shape. Directly draw on the media player over the video clip after selecting the pen tool. If you want to mask any video clip with any shape other than circle or square, the pen tool can be of great help. When you keep clicking, the path is created with straight consecutive lines shaped from two vertexes. When you use the Bezier path segment, it becomes easier for you to create smoother curves that give you greater control of the mask shape.Ī straight line with two vertex points is the simplest path that the pen tool can draw. Just draw the mask with the pen tool adding straight and curved lines. With pen tools, you can draw complicated masks around any object you wish to. If you wish to ensure where the effect was applied, is it within the mask or outside it, use the inverted checkbox for designating the effect at the right place. You can remove a few parts within the shot for creating the cropping effect by using the Crop Percentage in the Effects Control Panel.
