Dimmable led9/18/2023 For more information please read the article "What is Dali?" Many manufacturers supply LED drivers that will accept a DALI input. A DALI signal is delivered to the LED driver(s) via two wires that are in addition to the wires delivering the mains supply. DALI is the most widespread communications protocol for commercial lighting control in use today. The most common methods of controlling a driver are as follows:ĭALI (Digital Addressable Lighting Interface). In each case the driver will require a continuous supply of mains power plus a control signal to tell it what to do. There are several ways to control a driver, or instruct it what to do. The more important question for the specifier and installer is how the driver is to be instructed to make the LEDs brighter or dimmer. They are internal to the driver and have little or no effect on the end user and the quality of the dimmed light they will see. However, if a driver uses PWM or AM is generally of little interest to an installer or specifier. There are two mains ways that a driver does this - pulse width modulation (PWM) or amplitude modulation (AM) - and these are discussed below. LEDs work at low voltages on direct current.Īs a dimmer it raises and lowers the amount of electrical energy flowing out to the LEDs. This is necessary because LEDs don’t operate on mains. If desired, the driver can be the dimming type, performing the twin functions of a driver (transforming the incoming power from 230V AC to 12-24V DC) and a dimmer.Ī dimming driver performs two functions: it is both a driver and a dimmer.Īs a driver it converts the mains AC supply (typically 230V, 50Hz) to 12-24V DC. The LED driver – seen here to the left of the picture – is a separate item and is accessible to the installer. Installing a common design of commercial light fitting. This is how most dimming is achieved in commercial and industrial installations. If the driver is separate from the lighting fixture, or is accessible within it, then the best way to dim the LEDs will be by using a dimming driver. DIMMING LEDS WHICH HAVE A SEPARATE DRIVER So, to answer the very general question “Can LEDs be dimmed, and how do you do that?” one first has to determine if the driver is separate and accessible or if it is integrated with the LEDs. The driver is in the lamp base and the unit is sealed, so there is no possibility of connecting any dimming control wires. The LEDs and driver come as a single sealed item.Īn LED lamp. In LED lamps the driver is built-in and cannot be accessed. The driver is separate from the panel, so it is accessible for the connection of dimming control wires if required. This means that the driver is accessible to the installer so that, if the driver is the appropriate type, dimming control wires, in addition to the mains supply wires, can be connected to it.Īn LED panel with its driver. In commercial lighting fixtures, such as LED panels, downlights and spotlights, the driver is usually separate from the fixture. LEDs work at low voltages on direct current. Its main function is to run the LEDs at the correct voltage and current, converting the mains AC supply (typically 230V, 50Hz) to, usually 12 or 24V DC. So, to answer the question “Can these specific LEDs be dimmed?” it is necessary first to understand a little about LEDs and drivers.Īll LEDs need a driver, which is a piece of electronics. If it is practical or not to dim a particular LED lamp or lighting fixture will depend on the driver that is being used to control it. Yes, all LEDs can be dimmed, but it is not always simple. As a lamp or fixture is dimmed its lumen output decreases. The output of a lamp or lighting fixture is measured in lumens (lm) and is sometimes known as its “luminous flux”. What is Dimming? AN INTRODUCTION TO DIMMING LEDs / HOW TO DIM LEDS / LED DIMMINGĭimming means reducing the output of a lamp or lighting fixture.

Season three house of cards9/18/2023 Despite having no secrets between her and Frank and a willingness to participate in three-ways with their security detail, Claire has always been her own woman. Yet one of the largest misconceptions about the show has always been conflating Claire Underwood as a Lady MacBeth stand-in, quietly moving her husband’s agenda forward no matter what the cost, the real power behind the throne, etc. She pulls of some clever backroom deals here and there (and her flawless delivery of the line “Hand me a towel, would you?” practically makes the season), but it doesn’t prove to be enough, and despite her personal popularity being at an all-time high with the public, she tarnishes the Underwood brand politically, her forced resignation from her post being one of the terms that the Putin-esque President of the Russian Federation Viktor Petrov (a remarkable Lars Mikkelsen) demands before moving forward with a conditional agreement with Frank after a mysterious military operation kills Russian soldiers. Frank appoints her anyway, and before long she runs into numerous instances of her being disrespected or marginalized due to her lack of experience. Early on, she guns to be the Ambassador at the U.N., but despite some rather intense whipping of votes in what is arguably one of the best sequences in the entire season, she still comes up short. This season is all about Claire trying to find her place in the world, and Robin Wright carries off Clarie’s struggle with aplomb. Let’s not sugarcoat things though: despite the focal point, this season isn’t about Frank Underwood doing his best to consolidate his power. His gradual recovery becomes a focal point for the first half of the season, and his own life interweaves in interesting ways, his dedication to the Underwood’s being one of the show’s most relentless driving actions even as the storyline involving his former hacker buddy Gavin Orsay (Jimmi Simpson) remains the season’s weakest aspect. House of Cards‘ Third Season doesn’t waste much time setting things up, jumping six months into the Underwood administration where his own stock and popularity are at all-time lows, with even Stephen Colbert grilling Underwood and bringing out a venom we have rarely seen in him since his real-life interview with Julian Assange back in 2010.Ī majority of the first episode is actually seen from the perspective of Doug Stamper (Michael Kelly), Frank’s former Chief of Staff whose obsession with former sex worker Rachel (Rachel Broshnahan) lead to him being left for dead at the close of Season Two. While viewers have marveled at Francis’ gradual rise from Majority Whip to the Commander in Chief, our interest doesn’t so much lie in what Frank accomplishes so much as how he gets there, maneuvering and taking punches and somehow still coming out on top. He is the President of the United States, and slowly, his empire of power is unraveling all around him. “What are you looking at?” Frank Underwood sneers at us, the viewers, at the end of “Chapter 32”, the sixth episode in House of Cards third season. Crunch fitness around me9/18/2023 Tuck your knees toward your chest, then push your feet through and shoot them toward the ceiling, extending both legs above your head. Start in the hollow hold position, then extend your arms overhead, holding your band or towel tight. This move is similar to reverse crunches. Tuck your pelvis and engage your core, then slowly peel your upper back off the floor to perform crunches, always looking toward the ceiling. Lay on your back with your legs extended. Here’s how to do a side crunch for more tips. Look forward at all times, engage your core, then lift your upper body toward your hips. Lay on one side and extend your arms above your head, holding a resistance band or towel pulled tight. Your obliques run down your waist, so any twisting or side-crunching exercises will target them. Doing leg raises while your core is under isometric contraction (when the muscles contract without moving) will light a fire in your abs. Grip a resistance band or towel above your head and raise one leg at a time to touch the band. Tuck your pelvis toward your spine and lift your upper back off the floor - you can learn how to do a hollow hold here. Here are your exercises: Hollow body alt leg raises Unlike Kim Kardashian, whose punishing new strength training workout sees her in the gym for two hours per day with Greca. Ouch.

A post shared by Senada Greca, MBA photo posted by on Transcribe voice recording to text9/18/2023 Use a share button in another app (such as Voice Memos, or the Files app) that can share audio or video content, then select Drafts in the share sheet.Tap and hold the “+” button for new draft options, select “Transcribe…”.Here’s a few of the ways to access transcription: The most straightforward way to transcribe audio from an existing file is to open the audio or video file in Drafts. Most (but not all) common audio and video formats are supported. Expect the process to take less time than listening to the full audio, but not by a large margin. Processing time varies depending on your device and its capabilities. Due to time limits imposed by speech recognition, content longer than one minute is broken up and a separator ( =) inserted between segments in the transcription. The transcription process works by extracting audio content from the media, breaking it into segments suitable for processing by Apple’s speech recognition APIs, and transcribing each of those segments. Transcription may also be helpful to extract text from spoken word audio recording and video media of other types, but the quality of the results may vary significantly with the quality of the original recording, clarity of speech, etc. It is best suited to transcribing recordings of a single person speaking and supports dictation commands for adding punctuation, new paragraphs, etc. Transcription passes audio content through the same speech recognition process used in dictation. Drafts transcription features are here to help. Still, there are also times when you encounter recorded speech you might like to transcribe to text–perhaps a recording from the Voice Memo app, a lecture, or even a video of a conference presentation. It is often convenient to use Drafts’ dictation feature to create text content.

Mind palace exercise9/18/2023 What you can do is imagine yourself walking up the stairs, and bananas start falling down, raining down the stairs, and just toppling down step by step.Īnd then you go to the next room, which could be, you know, the hall at the top of the stairs. You get to the staircase, and you have bananas. Perhaps it's the staircase that's going upstairs. And so, you see that.Īnd then you walk on to the next room. See, without the method, my memory is not good that I think it was apples and so, you could perhaps look in the hall and you could imagine that the walls of the hall are just made out of apples like there are just walls of apples everywhere, and it's a long hall, and it's just walls of apples, green and red, or mixed. And now you want to remember the next one, and I think it was apples. You're in the hall that's next to the kitchen. And for this sake, I'm going to say it's the hall. You close the fridge imagine yourself doing that right now in your kitchen.Īnd now you walk to the next room. Once you've done that, say the fridge, you walk into the kitchen, and the first thing you do is you open the fridge, and it's all carrots. And when you open your fridge, it's full of carrots. Or perhaps you imagine there are lots of little carrots like all over, lying all over the floor. You imagine that orange is just a big carrot stretched out of the table. Maybe you have an orange cover on your kitchen table. Now you need to link the kitchen to carrots visually. What you could do is you could imagine five rooms in your house, and you could walk through them step by step at a time, and when you're in the first room say the first room is your kitchen. It would help if you planned a five-step journey. You have carrots, you have apples, you have bananas, you have bread, and you have milk. You have five things on the shopping list. I'm just going to use five things to make it simple. So, as an example, we're going to do this with a shopping list. Then, as they come across certain objects on that particular path, they will visually link them to the object they're trying to remember. The most common way that a lot of people do this is they have a particular route that they take through their house for example, they go through the house. So, the mind palace technique involves linking memories to some visual stimuli. The reason you can remember these certain things easier is that they're stored visually. Now, if I told you to visualize the last 10 words that you read in a book two hours ago, why is it that you can't remember those 10 words? It was only two hours ago the last time you were in your bedroom might have been a day ago, or something like that, you might not be in your house at the minute. If you think about it like if I told you to visualize your bedroom right now, you could easily see it. It's happening to you, either because you're there or because you've seen it in your head, then that stores a much stronger response or memory that you can access for years and years to come. If you just read something in a book, that's just one way of memorizing something, but you experience it if you see something. The Mind Palace technique essentially utilizes the way our brain processes visual memories compared to just auditory or written memories.

Van halen bumblebee9/18/2023 The ’79 Bumblebee tribute model features all of the original specs, including an ash Strat® body, bolt-on birdseye maple neck with oiled back finish, straight 12” radius birdseye maple fingerboard with 22 jumbo frets, katalox dots and black side dots, and skirted Strat-style “Tone” volume knob. 40 years later, EVH has meticulously recreated this wildly iconic guitar in the form of the 50-piece worldwide run of the ’79 Bumblebee. Eddie was Dime’s main influence and Bumblebee was Dime’s all-time favorite guitar. In an eternal sign of deep respect, Eddie’s original Bumblebee guitar was buried alongside Pantera guitarist “Dimebag” Darrell Abbott, who died tragically in 2004. Bumblebee remains a longtime favorite for Van Halen listeners everywhere. “Bumblebee,” as it would come to be known by fans, debuted on the cover of the 1979 album Van Halen II and was heavily played by Eddie throughout the 1979 world tour.Īlthough Eddie continued to wrestle with the overall capabilities of the guitar, the black-with-yellow-stripes theme became insanely popular. After all these modifications, only the original body, striped paint job, screw-eye strap hooks and Schaller® tuners remained from the first version of the guitar. He also swapped out the chrome volume knob with a Strat-style skirted “Tone” knob. He instead outfitted the instrument with a prototype two-point Floyd Rose® bridge and locking nut with retainer bar, becoming the first professional rock guitarist to use a locking-nut tremolo system. He rewound the pickup by hand, dipped it in paraffin wax and put copper tape around the windings.Įddie also stripped out the original Charvel bridge, leaving its six screw holes behind. After selecting a DiMarzio® Super Distortion humbucking pickup, he swapped out its ceramic magnet for an alnico 2 magnet from a Gibson® PAF. He installed a new Boogie Bodies maple neck with a natural headstock, unfinished back (which he has always preferred) and 12″-radius dot-inlay maple fingerboard. While pleased with the looks of the guitar, Eddie was less impressed with its tone and quickly began tinkering with it, as he was prone to do. Other features on the first-incarnation guitar (as pictured on Van Halen II) were a standard nut, single Mighty Mite humbucking pickup with transparent bobbins, single chrome volume knob, original Charvel six-screw brass tremolo bridge, and Schaller® tuning keys. While he tasked Wayne Charvel to cut the body, the maple neck was made by Lynn Ellsworth at Boogie Bodies with dot inlays on a maple fingerboard. “So it may have taken 40 years, but I now have everything I wanted back then - a bitchin’-looking guitar that plays and sounds great.”ĭuring the process of recording 1979 album Van Halen II, Eddie Van Halen sought something fresh to play other than his original “Frankenstrat,” which at the time was being heavily copied by just about every major guitar company in the world.Įddie had the idea to build a new guitar with an ash body and black-and-yellow-stripe paint job, with rear-loaded electronics so there would be no pickguard. “The ’79 Bumblebees that we’re making sound very much like how I always wanted the original to sound,” said Eddie Van Halen. Only 50 instruments will be produced worldwide, featuring all the original’s specs. The recreation of the historic black-and-yellow striped guitar celebrates the 40th anniversary of Van Halen II, and subsequent world tour. They also contain small parts and are not recommended for children under the age of 14.A very exclusive limited edition of Eddie Van Halen’s ’79 Bumblebee guitar is now in production.ĮVH unveiled the new ’79 Bumblebee tribute model at Summer NAMM over the weekend. *AXE HEAVEN® Miniature Replicas Look Great But Are Not Playable.
