11/25/2023 0 Comments E ink magic mirror raspberry pi![]() ![]() To create our magic mirror, we will create a ‘sandwich’ of the frame, a piece of observation mirror acrylic, and the screen. This can be built in an afternoon and is a great way to find out whether you want to take it to the next step and get working on something a bit bigger. In this tutorial, we’ll assemble a simple magic mirror using off-the-shelf parts. Although the results are undoubtedly impressive, it can make the hobby look a little daunting to the beginner, especially if you don’t have access to the necessary equipment to build a custom frame. There have been some impressive magic mirror projects as makers around the globe challenge each other to improve on previous designs. Would you like a magic mirror, but don’t fancy all that carpentry? Here’s a first project to ease you in without having to reach for the band-sawĪ Raspberry Pi Zero would seem ideal for this project, but MagicMirror2 is incompatible with that model and the original Raspberry Pi 1. It’s no wonder it won the number one slot in our best projects feature for The MagPi issue 50. Best of all, you can expand the capabilities of your mirror through the hundreds of community plug-ins available and, if you wish, you can write your own. This modular system takes away all the programming and design pain. Fortunately, the team at MagicMirror2, headed by Michael Teeuw (see The MagPi issue 54), have not only compiled tutorials and fostered a great community, they’ve also built their own open-source application. Let’s take a look at one of these makers and then have a go at building our own mirror.Ĭreating a good magic mirror requires experience in many disciplines including carpentry, electronics, programming, and graphic design. Although they come across as advanced builds, the community behind the projects have made significant advances in making magic mirrors accessible to all. The information displayed is typically what you need as you’re preparing to leave the house: weather, news headlines, and transit information. Initially created by combining old laptops and semi-reflective observation glass, they appear as normal mirrors but with text and images that appear to float in mid-air.

And "That Metal Show" led to his earning a part in a comedy this summer, "A Little Help," with Jenna Fischer and Chris O’Donnell. He thanks Howard Stern for putting him on the radio a lot, boosting his stand-up career. So we’ll be (messing) around and say, ‘What can we do to amuse ourselves?’ " I don’t drink like a fish or anything like that. "We’re on the road (for comedy tours) constantly. ![]() "Who would have thought heavy metal and prank calls would pay the mortgage? And now I’m on a heavy metal show for five seasons," he says. "I made prank phone calls on a show for five seasons. In a real way, Florentine is a contemporary American Dream, because he’s become richer and more famous following the passions he developed as a child - pulling pranks and listening to metal. "I say, ‘Listen to what a baby your dad was.’ And they’re like, ‘Yeah what a baby, Dad. It’s not like I’ve got a college diploma to show ’em."įlorentine already brings up this story with his brother’s grown kids. "Now I’ve got something I can tell the grandkids. "He fired me right on the spot, right on the highway," he says. One day, he was bored and hid an open can filled with poop in the back of his brother’s junky van.Ī week later, Florentine’s brother went crazy, pulled the van over on the Garden State Parkway and started ripping apart the van until he found the can. He believes if you prank someone, you deserve consequences, like when he was a kid, working construction for his older brother. "They say, ‘This guy is an idiot or an asshole, or both.’ " I didn’t want to make too many trips back and forth.’ "I’m like, ‘I’m not supposed to pull a chair up to the buffet and start eating from the buffet? I didn’t know that. He tries to allay tensions with angry victims by acting dumb. You never know the reaction you’re gonna get." ![]() But that’s the great risk of pulling pranks. I asked Florentine: If people pulled the pranks on him that he pulls on them, wouldn’t he want to punch them in the face? One day, he went on the street to interview Van Halen fans, pretending to be simultaneously talking to band members on the phone and relaying dumb messages back and forth. He’s still pulling practical jokes for VH1 Classic’s "That Metal Show," a combination prank/metal music show. "The show hasn’t been on the air for three or four years, and if I do the voice, the place goes nuts." His Special Ed still resonates with fans who go to Florentine’s stand-up shows. "Eventually, if we got through that list, we’d just open the phone book and start making phone calls. To protect myself from the potential ravages of "Crank Yankers," I started talking very cautiously and briefly to any odd squirrel who called.įlorentine now tells me that was a good plan because, normally, he and other comedians would be given a list of 30 phone numbers to call. Florentine would stay at Bellagio, then record his calls at a nearby studio.Īs the rock critic back then, I sometimes fielded bizarro calls from weirdos. The show was produced by Adam Carolla and former Las Vegan Jimmy Kimmel, who set up a lot of calls from here. Years back, he played Special Ed ("I got mail, yaaay") and other characters while making prank calls for Comedy Central’s "Crank Yankers."Īt the time, I knew "Crank Yankers" was operating from Las Vegas. Comedian Jim Florentine changed the way I talk on the phone to strangers. ![]() 11/25/2023 0 Comments Convert string to char![]() ![]() NOTE: a string is zero index based, similar to an array. It returns a character at the specified index of the current string. Use charAt() Instance MethodĬharAt() is an instance method of the String class. You can read more about the toCharArray() instance method in the Java documentation. I used the toString() static method from the Arrays utility class. We can use various ways to print an array. ("Length of \'vowelArray\' is " + vowelArray.length) Let's check the length of both vowels and vowelArray : ("Length of \'vowels\' is " + vowels.length()) When we convert a string to an array of characters, the length remains the same. Let's check out an example: // define a stringĬhar vowelArray = vowels.toCharArray() It returns a new character array based on the current string object. ToCharArray() is an instance method of the String class. Let's Convert a String to a Character Array 1. Now, we have a basic understanding about what strings, characters, and arrays are. ![]() For example, let's declare an array of characters: char vowelArray = For example: String vowels = "aeiou" What is an Array in Java?Īrrays are fundamental data structures which can store fixed number of elements of the same data type in Java. It's anything inside double quotation marks. A string is made up of a string of characters. For example: char firstVowel = 'a' What is a String in Java? ![]() It can be a letter, a digit, a punctuation mark, a space or something similar. A character is a single character enclosed inside single quotation marks. What is a Character in Java?Ĭharacters are primitive datatypes. I'll also briefly explain to you what strings, characters, and arrays are. NET Framework is the System.Char structure.In this article, we’ll look at how to convert a string to an array of characters in Java. Char has no identifier type character.įramework Type. Appending the literal type character C to a single-character string literal forces it to the Char data type. This means you can convert Char to String and will not encounter a System.OverflowException. If you pass an 8-bit argument to such a component, declare it as Byte instead of Char in your new Visual Basic code. NET Framework, for example Automation or COM objects, remember that character types have a different data width (8 bits) in other environments. If you interface with components not written for the. In any case, you should not use Char to hold numeric values. Char is an unsigned type and cannot represent a negative value. ' The following statement succeeds because it specifies a Char literal. ' This statement generates compiler error BC30512 because Option Strict is On. The second compiles successfully because the c literal type character identifies the literal as a Char value. The first assignment to the charVar variable generates compiler error BC30512 because Option Strict is on. ![]() If the type checking switch (the Option Strict Statement) is on, you must append the literal type character to a single-character string literal to identify it as the Char data type. You can use the Chr or ChrW function to convert an Integer value to a Char that has that code point. You can use the Asc or AscW function to convert a Char value to an Integer that represents its code point. Visual Basic does not convert directly between Char and the numeric types. You can use methods like IsDigit and IsPunctuation on a Char variable to determine its Unicode classification. Unicode uses the remaining code points (256-65535) for a wide variety of symbols, including worldwide textual characters, diacritics, and mathematical and technical symbols. The second 128 code points (128–255) represent special characters, such as Latin-based alphabet letters, accents, currency symbols, and fractions. These first 128 code points are the same as those the ASCII character set defines. The first 128 code points (0–127) of Unicode correspond to the letters and symbols on a standard U.S. The default value of Char is the character with a code point of 0. In some cases you can use Char(), an array of Char elements, to hold multiple characters. Use the Char data type when you need to hold only a single character and do not need the overhead of String. Each code point, or character code, represents a single Unicode character. Holds unsigned 16-bit (2-byte) code points ranging in value from 0 through 65535. ![]() 11/25/2023 0 Comments Recoverit safe![]() ![]() zip, etc.Īny Data Loss Situation: Recover deleted, formatted, or otherwise inaccessible files.

11/25/2023 0 Comments Hanley submarine drawing![]() ![]() “After all, we don’t have the blueprints.CSS Hunley The CSS Hunley was the first submarine to sink an enemy ship. All of them add into the mix of what happened and how this sub was operated,” Scafuri said. “We keep seeing parts that no one has seen in 150 years. What’s more, the scientists are finally beginning to get a handle on the inner workings of this thoroughly analog piece of military technology. Each step tells them more about the craft and its crew, from what their faces were like to the lucky gold token found in the captain’s pocket. “I would love to get to that point absolutely,” he said, but made no promises about whether it would be possible.įor now, scientists are focusing on the excavation, removing more of the corrosion and underwater matter from decades on the ocean floor. By measuring the forces, they finally had the data to back up a long-held suspicion.ĭespite these advancements, Scafuri says they were still a while away from being able to say definitively what had happened inside the submarine. “It was sufficiently large that the crew were killed.” In their 2017 study, researchers made a scale model of the submarine, then blew it up in a pond. “The pressure wave from the explosion was transmitted into the submarine,” graduate student Rachel Lance told Nature. It’s why researchers at Duke University proposed that they must have been killed instantly, perhaps by the blast from the submarine’s own spar torpedo. The Hunley was small and cramped-not even large enough for its crew to stand up straight-yet its men showed no attempt even to get away from where they were stationed. The discovery suggests two options: The crew may not have realized they were in danger, or not anticipated a need to surface quickly. The levers would have released 1,000 pounds of so-called “keel blocks,” bringing the submarine up to the surface and allowing the crew to swim away to safety. ![]() “It’s more evidence there wasn’t much of a panic on board,” Scafuri told the Associated Press. After removing layers of corrosion, silt and shells from the sub, his team of researchers found that the emergency levers were all locked in position. (Credit: De Agostini Picture Library/Getty Images)Īrchaeologist Michael Scafuri has been working on the submarine for 18 years. This suggests the crew may not have seen whatever sunk the sub coming. Researchers have found another piece to the puzzle: A hidden failsafe mechanism in the Hunley’s keel should have helped the crew escape the vessel, but it was never activated. The discovery has generated a raft of possible theories as to why it sank, and why the crew aboard didn’t seem to make any attempt to escape. Inside, all eight crew members were eerily in position at their stations, around a giant hand-crank that ran down the middle of the sub. Five years later, it was brought to the surface. Over 130 years after it sank, the submarine was found on the seabed in 1995. LISTEN: The Hunt for the Hunley on HISTORY This Week (It was recovered twice.) Its final sinking, shortly after it plunged a live torpedo into the hull of the Union warship USS Housatonic, has long mystified maritime and military historians. In a career of just eight months during the Civil War, between July 1863 and February 1864, the sub sank three times, killing nearly 30 men-including its inventor. ![]() But despite its claim to fame, it was a dangerous vessel to be inside. Hunley was a Confederate submarine with a crew of eight. Made out of 40 feet of bulletproof iron, the H.L.
