  • Crypto Mining with ESP32  + (Money is one of the most important inventiMoney is one of the most important inventions in human history. It is a medium of exchange, a store of value, and a unit of account. Money enables trade, commerce, and economic growth. However, money also has its limitations and challenges. For example, money can be counterfeited, stolen, or inflated. To overcome these problems, some people have invented a new form of money: cryptocurrency. Cryptocurrency is a type of digital currency that uses cryptography to secure and verify transactions. Cryptocurrency is decentralized, meaning that it is not controlled by any central authority or government. Cryptocurrency transactions are recorded on a distributed ledger called a blockchain, which ensures transparency and immutability. Some examples of cryptocurrencies are: * '''Bitcoin''': The first and most popular cryptocurrency, created in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto. Bitcoin has a limited supply of 21 million coins and uses a proof-of-work algorithm to validate transactions and create new blocks. * '''Ethereum''': A platform that allows developers to create decentralized applications (dApps) and smart contracts using its native cryptocurrency, ether. Ethereum uses a proof-of-stake algorithm to secure its network and enable faster transactions. Cryptocurrencies have many advantages over traditional money. They are: * '''Secure''': Cryptocurrencies use cryptography to protect transactions from fraud and hacking. Cryptocurrencies also have no single point of failure, as they are distributed across many nodes on the network. * '''Transparent''': Cryptocurrencies allow anyone to view the history and details of every transaction on the blockchain. Cryptocurrencies also have no hidden fees or charges, as they are based on peer-to-peer transactions. * '''Inclusive''': Cryptocurrencies enable anyone with an internet connection and a digital wallet to access the global financial system. Cryptocurrencies also have no barriers to entry or discrimination, as they are open to anyone regardless of their identity or location. * '''Innovative''': Cryptocurrencies foster innovation and creativity, as they allow developers to create new applications and services using blockchain technology. Cryptocurrencies also have the potential to disrupt various industries and sectors, such as banking, e-commerce, healthcare, education, and more. Cryptocurrencies are not without challenges and risks, however. They are: * '''Volatile''': Cryptocurrencies are subject to high price fluctuations due to supply and demand dynamics, market sentiment, regulatory uncertainty, and technical issues. Cryptocurrencies can also be affected by external factors, such as geopolitical events, cyberattacks, media coverage, and public opinion. * '''Complex''': Cryptocurrencies require a steep learning curve for users to understand how they work and how to use them safely and effectively. Cryptocurrencies also involve technical jargon and concepts that may be confusing or intimidating for beginners. * '''Unregulated''': Cryptocurrencies operate in a legal gray area, as they are not recognized or regulated by most governments and authorities. Cryptocurrencies may face legal restrictions or bans in some areas, which may limit their adoption and usage. Cryptocurrencies may also pose ethical and social issues, such as tax evasion, money laundering, terrorism financing, and environmental impact. Cryptocurrency is a new era of money that offers many opportunities and challenges for the future. Cryptocurrency is not just a technology or a currency; it is a social phenomenon that reflects the values and aspirations of its users. Cryptocurrency is not perfect or flawless; it is an experiment that evolves and improves over time. Cryptocurrency is not for everyone or everything; it is a choice that depends on one’s preferences and needs.at depends on one’s preferences and needs.)
  • What are the top 10 Indian stocks for a retirement portfolio for a person in mid-50  + (Most investors want to make investments thMost investors want to make investments that will provide them with significant returns as rapidly as possible while minimizing the danger of losing their principal. This is why so many people are on the search for great investment programs that will allow them to double their money in a matter of months or years while posing little or no risk. Unfortunately, there is no such thing as a high-return, low-risk investment product. In fact, risk and return are inextricably linked; they go hand in hand, i.e., the higher the risk, the higher the reward. When it comes to saving for their financial goals, Indians consider the following investment alternatives. '''1 Direct Investment''' Because stocks are a volatile asset with no guarantee of profits, they may not be suitable for everyone. Furthermore, it is difficult not only to select the suitable stock, but also to timing your entry and exit.The only silver lining is that stock has beaten all other asset classes in terms of inflation-adjusted returns over long periods of time. '''2 Mutual funds are a type of investment that allows you''' Equity mutual funds are mutual funds that invest largely in stocks. According to the Securities and Exchange Board of India (SEBI) Mutual Fund Regulations, an equity mutual fund scheme must invest at least 65 percent of its assets in stocks and equity-related securities. An equity fund might be actively or passively managed. '''3 Dept Mutual funds''' Debt mutual fund schemes are perfect for investors who want a steady income source. They are less volatile than equity funds and so considered less risky. Debt mutual funds invest primarily in fixed-income assets such as corporate bonds, government securities, treasury bills, commercial paper, and other money market instruments. These mutual funds, on the other hand, are not risk-free. They are fraught with dangers such as high interest rates and credit risk. '''4 National Pensions Systems.''' The Pension Fund Regulatory and Development Authority (PFRDA) manages the National Pension System (NPS), which is a long-term retirement-focused investment product. The annual fee for maintaining an NPS Tier-1 account has been reduced from Rs 6,000 to Rs 1,000. Stocks, term deposits, corporate bonds, liquid funds, and government funds are all included. Based on your risk appetite, you can decide how much you wish to risk. '''5 Public Provident Funds (PPFs).''' Compounding of tax-free interest has a substantial impact, especially in the later years, because PPFs have a 15-year tenure. It's also a safe bet because the interest earned and the principle invested are both backed by the government. Remember that the PPF interest rate is reviewed by the government every quarter. '''6 Bank Fixed deposit (FD)''' In India, a bank fixed deposit is seen as a safer investment than stocks or mutual funds. The deposit insurance and credit guarantee corporation (DICGC) guidelines cover each depositor in a bank up to a limit of Rs 5 lakh for both principle and interest as of February 4, 2020. Previously, the maximum principle and interest coverage was Rs 1 lakh. Depending on your preferences, you can choose between monthly, quarterly, half-yearly, yearly or cumulative interest possibilities. The interest rate is applied to one's earnings and taxed in accordance with one's tax bracket. '''7 Senior Citizens' Saving Scheme (SCSS)''' Most retirees' first option is the Senior Citizens' Saving Scheme, which is a must-have in their financial portfolios. As the name implies, this service is only for older citizens or early retirees. SCSS can be applied for at a post office or a bank by anyone over the age of 60. SCSS has a five-year duration, which can be extended by three years if the scheme matures. You have a maximum investment limit of Rs 15 lakhs. It's also feasible to create more than one account. SCSS interest is paid four times a year and is fully taxed. Keep in mind that the scheme's interest rate is reviewed and adjusted on a quarterly basis. The interest rate on an investment in the scheme, on the other hand, will not vary until the scheme matures. Senior people can deduct up to Rs 50,000 in interest from SCSS in a financial year under Section 80TTB. '''8 Pradhan Mantri Vaya Vandana Yojana (PMVVY)''' PMVVY is a savings plan for people over the age of 60 that guarantees a 7.4% yearly return. Depending on your preferences, your pension income may be paid monthly, quarterly, half-yearly, or annually. The minimum and maximum monthly pensions are Rs 1,000 and Rs 9,250, respectively. A maximum investment of Rs 15 lakh is allowed under the scheme. The project will last for ten years. The plan will remain in effect until March 31, 2023The senior individual receives a repayment of the amount invested at the conclusion of the term. The money will be paid to the nominee in the event of a senior citizen's death. '''9 Investing in Real Estate''' Your home is for your personal use only and should never be viewed as an investment. If you don't plan to live in the second house you buy, it can be used as an investment. The location of your home is the single most important factor that will determine its value and potential rental income. Capital appreciation and rental income are the two ways that real estate investments pay returns. '''10 Gold''' Having gold in the form of jewellery has its own set of problems, such as security and expense. Then there are the ‘making charges,' which typically vary between 6% and 14% of the gold price (and may go as high as 25 percent in case of special designs). For those who are interested, there is still time to purchase gold coins. A number of banks now sell gold coins. Paper gold is a unique way to get gold. Investing in paper gold is more cost-effective and can be done through gold ETFs. Such investment (buying and selling) takes place on a stock exchange when gold is the underlying asset (NSE or BSE). Investing in Sovereign Gold Bonds is another option to possess paper gold.

  • One Shot Keto reviews for Canada  + (One Shot Keto, like any other exogenous keOne Shot Keto, like any other exogenous ketones, has the same function: to boost ketone level in your blood and help the users to reach the stage called ketosis. Ketones are the derivatives of fat that are used by your body as a fuel. This is the most important aspect where most of the people seem to be confused. Let me clarify for you as simply as possible. First, I want to clarify the myths regarding the use of exogenous ketones. '''Does One Shot Keto Perfect Work?''' This is the most important aspect where most of the people seem to be confused. Let me clarify for you as simply as possible. First, I want to clarify the myths regarding the use of exogenous ketones. '''If keto diet is necessary, what is the use of One Shot Keto?''' If you can remain strongly committed to Keto diet no matter how hard it may be, restrain yourself from over-eating no matter how hungry you may feel and wait as long as it may take to lose your weight then you don’t need One Shot Keto or any other supplements. So, the bottom line is, One Shot Keto helps you a lot in your transition from your normal diet to Keto diet and to remain in the Keto diet. '''One Shot Keto Real-Life Usage Experience''' After seeing most of the people claim to have a positive experience with One Shot Keto, I decided to give it a try. Instead of trying at a single time, I took One Shot Keto at different times of the day. '''i. Morning''' I took One Shot Keto in the morning to check whether it curbs my appetite and it did, to some extent. It allowed me to go some extra hours without eating. '''ii. Afternoon''' It is very common to feel dull, lazy, and exhausted during the day, especially at the beginning of keto diet or when we are fasting along with keto diet. Although it wasn’t as quick as I expected, taking One Shot Keto in this situation actually energized me and definitely made me feel a lot better. It took around 10-15 minutes to actually see the results and only lasted a few hours but it felt like taking a painkiller. '''iii. Before Workout''' I could do some light to moderate workout after taking One Shot Keto. I got tired and needed more rest than the time I was on a normal diet but being able to workout on Keto diet is a huge plus point. Doing heavy exercise is a bad idea during keto diet as it may lead one shot keto, so, we avoided it. '''One Shot Keto Pricing''' If you are worry about the one shot Keto price, so just I will reveal here, it is available at afffordable price in canada.

  • Word Clock  + (Start assembly by making the stencil. You Start assembly by making the stencil. You can either get a stencil cut by a local sign writer to your own design, or use a pre-cut vinyl stencil from my web site. I have always felt that the clock looks more majestic if there is a border around the letters (I normally use about a 30mm border), but you can use whatever size you would like. Vinyl by itself is floppy, so it needs to be attached to a clear acrylic (Perspex) backing sheet to provide rigidity. Make sure that the acrylic sheet is the size you want the final clock to be.
    Before you start, mix up a couple of drops of dish washing liquid with a cup of water, and load that into a spray bottle. We will use this to make applying the vinyl lots easier.
    The vinyl stencil as supplied will typically be larger than required. This is so as to provide extra material for variations in face sizes. We need to cut the vinyl stencil to the final size of your acrylic sheet, allowing an extra 10mm allowance around the edges.

Next, ensure that your working environment is clean – vacuum your table if necessary – or work inside the house, instead of the garage. Lock up your Golden Retriever dog and your cats. If you get small particles between the vinyl and the Perspex, you will have enormous trouble making the surface look flat. Spend some time 'weeding' the stencil, by removing the letters that you don't want there on the final stencil. The removed letters will provide space for the light to shine through. Once you have removed all of the letters (being careful to leave the centres of letters such as 'A' and 'P' behind), apply some masking tape along each row so that when we remove the backing sheet, the centres of the letters stay in the correct spot on the stencil.s stay in the correct spot on the stencil.)

These will go into GND and Analog 5 in th arduino uno board. Next, solder an extra pin on the opposite side of the PCB. This will connect to Digital 9 on the arduino board. The speaker will also be soldered onto the PCB. Solder the positive end of the speaker to the pin which goes into analog 9 on the arduino. Solder the negative end of the speaker into the PCB. Then connect a short (5 cm max) piece of electric wire to the negative end of the speaker. The other end of the cable is soldered on the pin which goes into GND. Use a 1Mohm resistor to connect the pin which goes into GND and the one that goes into Analog 5 on the PCB (see photo above). It’s now time to add the antenna of your EMI detector.

Next, grab the 1Mohm resistor, and solder one end to the PCB pin which leads to A5 on the board, the other end to the PCB pin which goes into GND. To make the antenna of your device, take a piece of solid core wire (about 15 cm long), and solder one end of it to the PCB pin which leads to GND on the arduino nano. Finally, grap two short pieces of electric wire. You will use them to connect a 9V battery to the arduino nano and power the board.

  • PiKon telescope  + (The PiKon telescope is a robust design butThe PiKon telescope is a robust design but there are two issues that need care if you are to get the most out of your project. '''Dust and the Camera Sensor''' PiKon benefits from a very simple design that has just one optical component. The lens of the Raspberry Pi Camera is removed to allow imaging by the Optical Mirror.

  • 3D CNC milling avec CAM Fusion 360  + (<section class="step"><br />Be

    Before beginning CAM programming, you need to consider the part and the best approach to machining. These decisions depend on the shape of the model, the material, and the constraints of the CNC machine you are using. In this lesson, you will learn how these factors impact your machining strategy with respect to workholding, registration (making sure the CNC knows where the part is), and CAM settings.

    3D Toolpathing

    If you completed the CAD and CAM Class, you worked with 2D toolpaths, in which the end mill stays at a fixed depth (Z-level) throughout a machining pass, moving only in X and Y while cutting. This type of machining is ideal for prismatic parts - parts in which all machined faces lie normal to the machine tool spindle.

    When programming non-prismatic parts, such as molds or organic shapes like the the parts below, 2D operations are insufficient. You need to use 3D CAM operations, in which the end mill moves dynamically in X, Y, and Z.

    Workholding

    Workholding is the strategy for holding your part rigidly during the machining process. When programming with 3D toolpaths, workholding is an important initial consideration. This is especially true of parts that require machining on both sides, when the part will be flipped between setups.

    When programming for prismatic parts, you may have noticed that 2D and 2.5D CAM only requires a CAD model of the part that you want to machine, without any extra features for workholding attachment or registration. This is because the part takes the shape of a rectangular prism, which can be held easily inside a vise or fixed to a spoiler board.

    But what do you do when your shape is more organic or irregular, and also must be flipped to machine on both sides? In this case, you need to model additional material that will hold your part inside a vise, against a spoiler board, or flat against the bottom of the machine. It's very hard to program the CAM without having these features incorporated into your model.

    In other words, 3D flip machining requires that you model the stock you want left behind, as well as tabs to prevent your part from coming loose inside the machine. These tabs will be cut off and sanded down after machining, usually with a bandsaw and disk sander.

    Note: Another, more advanced, technique for workholding for irregular shapes in metal is a soft jaw system. You would machine your own custom aluminum jaws to use with a Lang or Kurt vise, and these custom jaws would hold your part after the flip. No tabs needed.

    For your serving spoon, you will have two tabs--one on each end--and a rectangular prism of stock that will hold the spoon flat after the flip. When modeling, it's a good idea to make your stock and tabs another body, separate from your part.

    Registration

    Because the spoon will be machined from both sides (flip machining), you need a way to ensure that the CNC machine can locate the part accurately after it has been moved. This is called registration.

    If you have used the Haas before, you're familiar with using a probe to locate your part . The DMS, however, like many table routers, does not have a probe. When using the DMS to locate the origin of your Work Coordinate System (Work Home), you will insert a tool into the spindle and jog it to the correct location. It's common to trap a piece of paper between the stock and the tool to ensure that Z is correct. In the DMS machine class you will learn how to enter the codes to set your WCS in this way. As you might imagine, this system is not accurate, because you're just "eyeballing" this location.

    This means that if you have a part that requires flip machining, you need to consider how to get the two sides to line up properly with one another. There are lots of options, and they all have advantages and disadvantages based on the specifics of your part. Some common methods include:

    --Attaching stops to your spoiler board (waste board under your part that can be machined) or machine bed

    --Machining a contour into your spoiler board, then placing your stock exactly inside that contour

    --Drilling holes for dowels that go into the spoiler board beneath your part (most accurate)

    This final technique is the the method you will use for the spoon. While machining the front side of the spoon, you will also drill three holes through the stock and partially into the spoiler board. After you flip your part, you will insert dowels through the holes and into the spoiler board that will align your part perfectly with your first side.

    CAM Settings

    The specifics of the project - machining wood on the DMS router - will also determine some of the choices you make when programming toolpaths.


    
-Tool numbering

    If you are a Pier 9 shop user, you will be using the DMS tool library. When you have simulated and finalized your CAM program, make sure that your tools are labeled in the chronological order that they are used. You will learn later in this class how to edit tool numbers.

    Remember that the chronological tool numbers in your program do not correspond to the numbers in the DMS tool library drawer. For instance, the fifth tool you use in your program might be the 1" Rough Short End Mill, which is labeled #34 in the DMS library. You will see the DMS library number in the comment for each tool, which will appear in your setup sheet (machining plan). You will learn later how to generate setup sheets.

    If you are not using Pier 9's DMS, you'll either be using custom tools, or tools from your own tool library. If using your own library, be sure to label your tools in the chronological order they will be used.

    -Rules for roughing

    Machining in wood or plastic on the DMS is not high speed machining (HSM). This means that you may use Adaptive toolpaths for roughing, but you cannot use the whole length of the cutter.

    When machining wood or plastic, follow the Stepover and Stepdown Rule: The stepover and stepdown should never exceed 50% of the tool diameter.

So you should confirm the network runs well when you are downloading the songs or playlists from Spotify. If it is this reason that causes your problem, you should download the songs again with a good internet connection. 3. Your downloads of songs from Spotify exceed the 10,000 number limit. As Spotify only allows Premium users to download up to 10,000 tracks in total, you should check whether you have hit that limit or not. If so, Spotify will delete the previously downloaded songs automatically if it finds you adding some new tracks. Normally, you'll be noticed by Spotify with a warning message once you reached this limit. 4. You may be out of Spotify Premium. So you need to verify your premium membership.  You are required to log into your account online every 30 days even if you use Spotify Offline mode. Otherwise, the downloaded songs would disappear from your Spotify account.

The result of learning these certificates is to make you useful, not just this certificate. it works. Some people ask whether the current certificates are still useful? I actually answered this question just now. Certification is useful, but only if you really understand it, not just buying a certificate. This certificate is not the same as a university diploma. It requires you to be able to work. The current situation in the industry is difficult because there are too many people looking for a job with a certificate. They actually don’t understand anything, and they are also very good at companies. No value, of course they don't want you. As for the concept of understanding, you can probably say that as long as you give you the equipment, you can adjust it, and you can solve the problem if it fails. This is called understanding, and it depends on your hands-on practice. You should set aside a few months to prepare for the exam, and work steadily to learn, which will help your future. Learning is lifelong. You have to distinguish clearly between the training based on textual research and the training based on learning technology. It's like taking a four-level certificate and learning spoken English, each taking what you need is very different.

High-pressure operations under the production network involve the required professional qualities, and the mentality of learning is simple.

After that, you can gradually strengthen all aspects of technology according to the needs of the work. In general, the learning and upgrading of technology has never stopped for the senior engineering who has been in the industry for decades, but one is enough to support your entry into the industry. Or a solid foundation to start is indispensable.

  • Energy module for People Pedal Power  + (You can chose between different buffering You can chose between different buffering systems, an battery, a supercapacitor or a flywheel. We chose a supercapacitor. A supercapacitor is an electronic component able to hold a charge. It can be used in the same function as batteries with the following differences : + a capacitor is easier to recycle than most batteries (references will follow). + a capacitor can provide and absorb a higher peak power. – the voltage varies with the charging state of the capacitor (it needs an additional converter to provide the voltage of the system) – the energy by weight capacity is less interesting than with batteries. – the cost by energy is higher. – the lifetime is quasi infinite (1M cycles). The energy storage of a supercapacitor : energy = 1/2 * C * voltage difference^2 http://www.engineeringtoolbox.com/capacitors-energy-power-d_1389.html ex = 1/2 * 500F * (16-12)^2 = 4000J = 1.11Wh = 1 cyclist for 1min20sec http://www.maxwell.com/products/ultracapacitors/16v-large-modules/documentsltracapacitors/16v-large-modules/documents)

  • Purificateur d'air anti-Covid  + (Les calculs des concentrations et des quanLes calculs des concentrations et des quantité de virus respirées sont détaillés ici: [https://wikifab.org/images/a/ad/Purificateur_d_air_anti-Covid_CalculsConcentrations.pdf Purificateur_d_air_anti-Covid_CalculsConcentrations.pdf] Ces calculs sont nécessaires pour appréhender clairement l'action des purificateurs. La comparaison du débit de traitement avec le volume de la pièce est une indication intéressante mais pas suffisante pour appréhender la dynamique des phénomènes. '''Photo 1:''' On y voit l'évolution des concentrations pour deux volumes de salles (75 et 150 m3) et trois débits différents (0, 300 et 600 m3/H). Si on ne fait rien, la concentration de virus croît linéairement avec le temps. Le traitement par les purificateurs limite très rapidement cette croissance en une asymptote dont le niveau est inversement proportionnel au débit du traitement. '''Photo 2:''' On y voit l'évolution des virus respirés pour deux volumes de salles (75 et 150 m3) et trois débits différents (0, 300 et 600 m3/H). Si on ne fait rien, la quantité de virus respirés croit comme le carré du temps passé. Le traitement par les purificateurs limite très vite cette croissance qui se réduit à une croissance linéaire. On note que la vitesse d'ingestion du virus ne dépend plus de la taille de la salle mais seulement du débit de traitement. '''Photo 3:''' On y voit l'évolution de la réduction de la quantité de virus respirés (réduction du risque) en fonction du temps pour deux volumes de salles (75 m3 et 150 m3) et pour deux débits différents (300 et 600 m3/H). On peut noter que l'intérêt est le plus grand lorsque l'on doit passer du temps dans une petite salle.oit passer du temps dans une petite salle.)

  • Showerloop - Guide 2: Filters  + (Laser cut or CNC the files in [http://googLaser cut or CNC the files in [http://google.com this pdf]. Since laser cutters handle cutting a bit differently there may be come problems with the file. Generally red / hairlines (0.001mm) is for cutting and black is for engraving.
    If you don’t have access to a laser cutter or CNC machine, a manual router can be used to cut out the groove in the filter and the whole shape if need be. To cut a perfect circle with a router a special tool may need to be made (look for circle jig on youtube).
    The lids and mounting plates can also be a single piece if you are using thick material. Four 10cm diameter x 50cm filters are required to have an appropriate flow rate of 10l/min. With 6.6l/min two filters are sufficient and 1 filter for 3.3l/min. The surface area is more important than the length of the filter because that determines the flow rate through the filter and thus reaction times. I use 10mm thick acrylic sheets for the lid and compression disks but I have used 4-5mm acrylic sheets in previous prototypes and glued them together with decent results.
