7/27/2023 0 Comments 30 amp extension cord endsSome early unearthed plug and socket types were revised to include an earthing pin or phased out in favour of earthed types. Some types can also include fuses and switches.Ī third contact for a connection to earth is intended to protect against insulation failure of the connected device. Sockets may have automatic shutters to stop foreign objects from being inserted into energized contacts. Contact pins may be sheathed with insulation over part of their length, so as to reduce exposure of energized metal during insertion or removal of the socket. Sockets may be recessed and plugs designed to fit closely within the recess to reduce risk of a user's fingers contacting the live pins. Plugs are shaped to prevent finger contact with live parts. Protection from accidental contact ĭesigns of plugs and sockets have gradually developed to reduce the risk of electric shock and fire.

Depending on the supply system, one or both current-carrying connections may have significant voltage to earth ground. Single-phase sockets have two current-carrying connections to the power supply circuit, and may also have a third pin for a safety connection to earth ground. To reduce the risk of electric shock, plug and socket systems have safety features in addition to the recessed contacts of the energised socket.Ī socket may be surrounded by a decorative or protective cover which may be integral with the socket. Some plugs have built-in fuses for safety. Some plugs have female contacts that are used only for an earth ground connection. The plug is a male connector, often with protruding pins that match the openings and female contacts in a socket. Typically no energy is supplied to any exposed pins or terminals on the socket, for safety.Ī plug is the movable connector attached to an electrically operated device, and the socket is fixed on equipment or a building structure and connected to an energised electrical circuit. Clockwise from top left: CEE 7/4 (German) plug a matching CEE 7/3 socket with exposed earth (ground) projections on circumference of socket CEE 7/5 (French) socket with projecting earth pin. Plugs and sockets may sometimes combine male and female contacts. Some multi-standard sockets allow use of several types of plug improvised or unapproved adaptors between incompatible sockets and plugs may not provide the full safety and performance of an approved socket-plug combination. Coordination of technical standards has allowed some types of plug to be used across large regions to facilitate trade in electrical appliances, and for the convenience of travellers and consumers of imported electrical goods. Today there are about 20 types in common use around the world, and many obsolete socket types are found in older buildings. A proliferation of types developed for both convenience and protection from electrical injury. Plugs and sockets for portable appliances became available in the 1880s, to replace connections to light sockets with wall-mounted outlets. Different standard systems of plugs and sockets are used around the world. Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type. AC power plugs and sockets connect electric equipment to the alternating current (AC) mains electricity power supply in buildings and at other sites.

We have analysed this beautiful evening poem here. It seems a rather straightforward poem, but, as with that other Frost poem, its simplicity is only on the surface, and is belied here by several things, including the sophisticated rhyme pattern Frost employs. This is one of the most perennially popular evening poems, so had to be included here!įrost called this poem ‘my best bid for remembrance’. One of Frost’s best-loved poems if not the best-loved (the rival would be ‘The Road Not Taken’), ‘Stopping by Woods’, like Hardy’s ‘The Darkling Thrush’, takes a wintry evening as its setting but goes further into the woods than Hardy did (who was merely leaning ‘upon a coppice gate’). Robert Frost, ‘ Stopping by Woods on a Snowy Evening’. With visions, alien to long streets, of Cytharea The poem is short enough to be reproduced in full here:Īlluring, Earth seducing, with high conceits Hulme wrote as an illustration of what he thought modern English poetry should be, following the French vers libre (or free verse) model.įew poets before Hulme had thought to compare the red sunset to the naked flesh of a mistress of King Charles II, but the unusual simile only makes his poem all the more arresting and his description of the evening sunset – as seen by a London-dweller – even more visceral and vivid. However, Housman seems to have borrowed the phrase from Shakespeare’s Macbeth (‘The gaudy, blabbing, and remorseful day / Is crept into the bosom of the sea’) – but what he does with the phrase is quite arresting and memorable here.Īlong with his more famous poem ‘Autumn’, this was one of the first two poems T. The last line of the poem gave Colin Dexter the title of his final Inspector Morse novel, The Remorseful Day in the books, Housman is Morse’s favourite poet. Okay, so the first two stanzas of this poem address the morning and daytime, but it’s for the sublime final stanza that we’ve included this poem here. Housman, ‘ How clear, how lovely bright’. The poem’s speaker leans upon a woodland gate and views the land around him as a symbol of the events of the nineteenth century, the ‘Century’s corpse outleant’ the speaker is made a part of the scene, not just a detached observer, as ‘outleant’ echoes the speaker’s own action at the start of the poem (‘I leant upon a coppice gate’).Ī thrush appears, and sings so joyfully that the speaker is convinced that the bird knows something he does not – that the thrush singing in the twilight knows of brighter days to come.Ħ. This might work well with a ‘consequences’ story frame: a framework of actions already written where pupils add in nouns taken from the image to make a story.This classic Hardy poem captures the mood of a winter evening as the sun, ‘the weakening eye of day’, sets below the horizon and gives way to dusk on New Year’s Eve. To stimulate creative writing: pupils could pick two or three elements of the picture and combine them to stimulate a story. To support reading of individual poems – the image can act as a visual reminder of topics, themes or narratives for students while they are completing work on poems To stimulate pre-listening discussion about what the poems might be about Using the images:Įach programme is accompanied by a composite picture inspired by the poems in that programme. Students can read the text of the poem before, during or after listening to the recording and there are suggestions in these notes for pre-, during-, and post- listening activities. You can listen to them in their entirety or listen to and focus on one poem at a time. The programmes can be used in a variety of ways. These poems are read by the actors Maxine Peake and Julian Rhind-Tutt. The final two programmes focus on classic poetry and include a selection of well-known poems often taught at Key Stage 2. Each of the first 6 programmes profiles a different contemporary children’s poet who introduces and then reads a selection of his or her work. There are eight programmes in this series. 7/27/2023 0 Comments Happy birthday sweetie dsughterIf you ever need an ear to listen just turn to me, because you will never be too old for girl’s night with your mom.ġ3. I still remember all the nights we spent just staying up talking and eating ice cream. Think back to 98 Degrees and just “Be True To Your Heart.” Yes, that was a cheesy 90’s reference, but don’t pretend like you didn’t love them.ġ2. Daughter, if you are lost in life just take a step back and remember your teenage years. I promise you that I will devote the rest of my life to providing you with unlimited love and affection.ġ1. Happy birthday to my beloved daughter who deserves only the very best on her special day. Happy birthday from your loyal subjects a.k.a. Now, on your birthday, we get to treat you like the queen you are. From the day you first came home from the hospital, you ruled our house like a tiny little tyrant. I hope your special day is just as sweet as you are. Daughter, you remind me of your birthday cake you are full of sweetness and sprinkle my life with love. Too embarrassed, yes, but never too old! May your birthday be filled with lots of indulging in goodies this year.Ĩ. I hope you know that you will never be too old to come home and be pampered like a princess. Your presence in my life has added nothing but value and joy to it.ħ. Of all the presents I have ever been given in my lifetime you were the most beautiful gift I have ever received. Thank you for showing me how wonderful being a parent is. I never knew I could love something so tiny so much, but the day you came into my life I was overwhelmed by all the love I had for you. May your birthday be just as spectacular as you are.ĥ. Just the other day you could barely stand, and now I get to watch you run the world! Watching you grow up has been such a joy, and I know that only greatness lies ahead for you. You are such an inspiration to me, and I hope you feel surrounded by love and warmth on your birthday.Ĥ. You renew my faith in the world because any world that has as incredible a person as you in it is one that can only be good. Heal this world with your smile and love. You can be an adult woman, but you are always a small princess for your mom and dad. Happy Birthday to the best daughter ever.Ģ. Look forward your future without any sign of doubt or fear. You are the main reason we smile every day. You are our beloved daughter, our pure angel. Your princess will definitely love them because she loves you as much as you love her! Happy Birthday Wishes for Daughtersġ. Grab one or two of these birthday wishes and quotes we compiled for all the daughters celebrating their birthday today. You can show your love through the words and the perfect way to tell her you love her, is to give her the right kind of birthday wish. Aside from the gifts expensive or simple, it would be wonderful if you could tell her the sweetest birthday wishes as well. We know how special your daughter is and for her birthday, you would want to give the best celebration. But the difference between the two does not mean one is more loved than the other. Daughters are special because they are more affectionate, soft-spoken, and patient compared to sons. They share the same interest such as scheduled parlor visits, cooking, singing, gardening, and many other things. Daughters tend to be closer to their mother mainly because their gender is the same. If you really want to know what true love means, ask a mother or a father. A child who came from her flesh and blood. One of the most exciting and memorable events in a woman’s life is giving birth to a child. 7/27/2023 0 Comments Slomo gun shotThe city of Halstead is spending $85,000 to refurbish one of its main tourist attractions: the swinging foot bridge in the town's Riverside park.

7/27/2023 0 Comments Node url encode decodeSimply using Base64 encoding, which will obfuscate and create short tokens is not a reliable security solution as Base64 strings can be easily decoded. Essentially: const value = 0123456789 // Initial valueĬonst token = encrypt(value) // Encrypted tokenĬonst decryptedValue = decrypt(token) // Decrypted value In that project and some applications, where we want to encode and encrypt sensitive data, we also need to be able to decode and decrypt this information, when we need it, anywhere in our application, as such that the decrypted value is not altered during the process ensuring Data Integrity. This means that the same encryption key must be used to decrypt the data. In this case, we both shared the same encryption key, a process known as Symmetric Encryption. However, JavaScript has the problem of not properly handling large integers, as it can only store signed or unsigned integers of up to 53 bits. Ruby provides straightforward handling for signed and unsigned big endians using pack() and unpack() methods for accessing underlying bits and bytes. It involved how we could safely pass identifiable user information such as phone numbers encoded and encrypted by a third party service in Ruby, to be decrypted and decoded into our application for the user. In a project that I worked on a while ago, I was presented with a problem that wasn't very unique. If you want to learn more about Base64 conversions in JavaScript, read this guide.LinkedIn logo for sharing a link Twitter logo for sharing a link Reddit logo for sharing a link You can even use it to perform ASCII, HEX, UTF-16, and UCS2 encodings and decodings. The Buffer object is not just limited to Base64 conversions. We looked at how to use the native Buffer module to perform the Base64 encoding and decoding in a Node.js application. That's all for Base64 encoding and decoding in Node.js. log (str ) // Base64 Encoding in Node.js Conclusion toString ( 'utf-8' ) // print normal stringĬonsole. from (base64, 'base64' ) // decode buffer as UTF-8 const str = buff. Here is what it looks like: // Base64 encoded string const base64 = 'QmFzZTY0IEVuY29kaW5nIGluIE5vZGUuanM=' // create a buffer const buff = Buffer. All you need to do is create a buffer from the Base64 encoding string by using base64 as the second parameter to om() and then decode it to the UTF-8 string by using the toString() method. The Base64 decoding process is very much similar to the encoding process. The second parameter in om() is optional when dealing with plain-text (UTF-8) strings. In the above example, we created a buffer from the string and used the toString() method to decode the buffer as a Base64 string. log (base64 ) // QmFzZTY0IEVuY29kaW5nIGluIE5vZGUuanM= toString ( 'base64' ) // print Base64 stringĬonsole. from (str, 'utf-8' ) // decode buffer as Base64 const base64 = buff. Here is an example: // plain-text string const str = 'Base64 Encoding in Node.js' // create a buffer const buff = Buffer. If no character encoding is specified, UTF-8 will be used as the default. This method takes two parameters, a plain-text string, and the character encoding, and creates a buffer or binary data array for the given encoding. To convert a string into a Base64 encoded string, we first create a buffer from the given string using the om() method. Let us look at the below examples that explain how to use the Buffer object to perform Base64 encoding and decoding in a Node.js application. This includes to and from UTF-8, UCS2, Base64, ASCII, UTF-16, and even the HEX encoding scheme. The Buffer object provides several methods to perform different encoding and decoding conversions. Internally, Buffer represents binary data in the form of a sequence of bytes. Buffer is available as a global object, and you don't need to explicitly require this module in your application. Luckily, Node.js provides a native Buffer module that can be used to perform Base64 encoding and decoding. These methods are part of the window object and are only available in the browser. Unfortunately, Node.js doesn't support standard JavaScript functions like atob() and btoa() for Base64 encoding. Today, you'll learn how to do the Base64 encoding and decoding in a Node.js application. In an earlier article, we looked at how to Base64 encode and decode a string in Java and JavaScript. 7/27/2023 0 Comments Relieve bed bug itchNow, you soak yourself in this bath for about 15 minutes.Īs we know, aloe vera is known as a plant that can help improve skin health by moisturizing skin, protecting the skin, and healing wounds. You may combine with a little peppermint essential oil. You prepare one-half cup of colloidal oatmeal (the best is ground oatmeal) and warm bathwater.You should repeat this process 3-4 times a day for a week.Next, you keep waiting for 15-30 minutes before washing it off.Then, you apply it on your affected area. First of all, you mix a little water with some teaspoons of oatmeal to have a fine paste.Because of its anti-inflammatory and soothing properties, oatmeal is an excellent remedy to decrease skin irritation and itching that is caused by many insect bites. Oatmeal is famous for treating skin diseases such as eczema and psoriasis. You should repeat this process as you need.Then, you place it on your affected area for 15 minutes.Firstly, you cool a moist and used tea bag by putting it in the refrigerator at least 30 minutes.Using moist tea bags to treat bites of bed bug may help you in combating the itching and swelling which is caused by the bed bug as well as other insect bites. Thanks to containing antioxidant and anti-inflammatory properties, tea bags have many benefits on health, especially for heart health. In order to have a more soothing effect, you should cool the pieces firstly in the refrigerator.You should allow it to be on for 10- 15 minutes.You put a piece of cucumber slice or peel on your affected areas.Besides, this vegetable may reduce inflammation and give relief from swelling and itching caused by bed bug bites because it contains many minerals and antioxidant properties. You may repeat this process as you need.Ĭucumber slices and peels contain a large amount of caffeic acid and vitamin C that are good for health.You should keep it staying on there for about 10 minutes and remove.Then, you apply it to your affected area.At first, you soak a cotton ball or clean cloth in witch hazel.However, it has tannins that contain a mild anesthetic, and thereby, it may help in calming itching that is caused by bites of bed bugs. It is mostly applied as a facial cleanser. Witch hazel is known as a liquid astringent which you can buy from a drug store. 7/26/2023 0 Comments Arduino pwm frequencyKeeping in mind that I don’t have board size constraint, and I need to reach similar specs of the previous drivers (but with a modern and more reactive solution), do you have any suggestion to something that could be easily retrieved?įinally regarding the S49E, weird things happens, if I load on the board the SimpleFOC Hall Sensor test Example and I move the BLDC motor it works fine, but then If I load another example where I try to move the motor, such as the open loop one, when I load back the Hall Sensor example If I rotate the rotor by hand as before, the debug value wiggles between 2 values and it does not move from 0, this happens for 2 or 3 minutes, then it goes back to normal (anything changed on the board, just the firmware, this is extremely strange). So redesigning and winding motor no problem.īut the drivers that you used are not available, anywhere… Have a linear encoder magnetic for closed loop. Yet another high-power 50A integrated BLDC Board announcement (for this, I planned to buy a stock of these: Double BTS7960 and unsolder the drivers for my boards (so as you see I am desperate). I am completely aware that they are obsolete, but I really can’t find a similar solution that is available in component stores this days… Regarding the B0505LS as I said before it was just for overkill the Isolation, currently my MCU power supply is a combination of a 1000uf low esr capacitor, followed by a 100nf ceramic one, then I prepare the 12V power line (that I need for other things not yet implemented) with a SRH05s12 which output then goes into a L78L05ACZTR that goes to the MCU, between the 5V and the MCU I wanted to add the B0505LS, but I am no more so sure that this is a wise regarding the Drivers, I used that exactly in the way I see in the Layout Considerations you quoted. I will post the design in the next both of you have said that I2C suffer when used with cables, should I use another protocol that this magnetic sensor are providing me? I know that SPI is worse noise wise, I think that what remains is PWM, I never used that sensor using this protocol but I saw that you have created an implementation in the SimpleFOC library for that, what are the advantages and disadvantages of using PWM in this specific case? My board design is currently just double layer, I don’t have size constraint this time, so I can adapt to the best solution possible you suggest (even if it is a single layer one). In theory, from that side I should be covered. I saw your previous posts in other threads, I am currently using a setup with Arduino Uno and somewhere you wrote that it (in theory) it should not need pullups for I2C. It should already have pullup resistors on board, so I didn’t added any other. Regarding the AS5600, for now I am evaluating that using this ready board: Yes I agree with both of you regarding the fact that I should face the problem and not hide away from it, I am just curious to see if this “overkill” solution would give some results! eheh Voltage spikes) by series resistors in the range of 10 kΩ. The digital inputs need to be protected from excess currents (e.g. A reasonable value for this capacitor would be about 470 nF. > current for the switching phase via a low inductance path and therefore reducing noise Or B6 bridge design, the voltage offset between the GND pins of the different devicesĪ ceramic capacitor from VS to GND close to each device is recommended to provide Ground pin of the device (GND / pin 1) is minimized. Therefore it is recommended to assure that the offsetīetween the ground connection of the slew rate resistor, the current sense resistor and Necessary in all switched high power bridges. Stray inductances have to be minimized in the power bridge design as it is I believe in another thread I posted an MCU that burst because I didn’t do that, luckily that was just an experiment, and noone got hurt.ĭue to the fast switching times for high currents, special care has to be taken to the PCB Have you done that? Else, you will get PWM output bleeding through ground back into whatever is connected. Just a side comment, that’s all.Įdit: One last thing, all IFX/BTN/BTS drivers have the same problem where the power ground is also logic ground, so you must take extra care to disconnect them. These are really old, discontinued drivers. 7/26/2023 0 Comments Download teamviewer 64 bit
