VERBIS - Desktop 8x8 RGB LED Matrix Word Clock + ('''Wooden photo frame''' You can make you … '''Wooden photo frame''' You can make your own frame, there are a dozen of articles about this, even here on Instructables. But a simpler solution would be finding a framing company where you can order a personalized frame with your required dimensions and you can choose from many frame types. This is exactly what I did. I ordered my frames with a specific dimension: the framed photo, in my case object (display) is 80x80mm. I also asked for an accurate dimension, I didn't want the frame to be too big for the 3D printed plastic grid. '''Plexiglass support''' The plexiglass support can be also be made DIY but for an amateur it is not very easy to cut and blend plexiglass. So I ordered several supports from an advertising company that makes all kinds of plexiglass objects. The dimensions I used are: width - 120mm, first part length - 180mm, second part length - 50mm, 15° bending angle. '''Display plexiglass sheet''' The 3mm grey smoked plexiglass sheet can be cut from a bigger sheet, obtaining the required 80x80mm dimension. '''Plastic grid''' The STL file for 3D printing can be downloaded from [https://www.tinkercad.com/things/arRYOVE5Lbk Tinkercad] '''Display Printed Paper Sheet''' The SVG file for the Printed Paper Sheet is attached, and it can be edited with Inkscape. You can make your own display layout based on this SVG file, I used [https://www.wordsearchkit.com/ Word Search Construction Kit] software to generate a words layout for the time display. You can print the file repeatedly on the same sheet of paper to achieve a good, opaque, black background. I got very good results with a cheap inkjet printer and standard white copier paper. I cut off the layout with a pair of scissors. '''Plastic box for electronics''' The files that you can 3d print are also on [https://www.tinkercad.com/things/2vKBHQ1HEI3 Tinkercad].

Focus the flame on the areas above and below where you will do the bending so that part doesn’t get hotter and thus weaker than the rest of the steel. Once the copper turns blackish and starts making a cool psychedelic rainbow effect you know the copper is warm enough to begin bending. Turn off the flame and wait a moment. Once the pipe has cooled a little use the pipe bending tool so make an appropriate bend. This is more craft than technical skill and you just have to observe and see how the metal flexes.

Don’t put too much pressure on one spot, this may result in a distorted pipe. You want to keep the diameter of the inner pipe as even as possible. Use a pipe bending tool.

This way, when the PCB will be mounted on the arduino uno board, one end of the resistor will connect to A0, the other one to GND. Next, cut two pieces of electric wire, each about 20 cm long. The length doesn’t really matter, however, longer wires will enable you to distance the arduino board further away from liquids. Solder one end of one wire to one end of the resistor. This will connect to A0 on the board. Solder the other end to n° on the PCB. The latter will then connect with A5 on the arduino uno board. Strip off the other ends of the electric wire you just soldered onto the PCB, and connect them to the top of the binding post. Now cut two short pieces of electric wire (about 10 cm long each), and strip off both ends of each wire. Connect one end of each to the bottom part of the binding post.

Showerloop - Guide 2: Filters + (There are 2 lids per filter, the top lid a … There are 2 lids per filter, the top lid and bottom lid - duh. A hex nut is used to fasten the hose nipple (facing away from the filter) to the filter lid. The dimensions of hex nuts and/or hose nipples may vary regionally so it's best to get them first,check the measurements and modify the file if needed. In the picture of the lid only a circle was etched/milled into the acrylic lid to fit the hex nut but the design was later revised to have the shape of the hex nut itself, thereby fastening it to the lid so that it could no longer rotate (and prevent fastening) when adding the hose nipple on the outer side of the lid. hose nipple on the outer side of the lid.)

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.

Crypto Mining with ESP32 + (Money is one of the most important inventi … Money 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.)

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. I will recommend about purcharse Keto One Shot from Official website.harse Keto One Shot from Official website.)

Arduino to ThingSpeak via SIM800 No Wi-Fi + (The legacy project documents that were ori … The legacy project documents that were originally designed with the SIM800 module may necessitate slight adjustments. This project will prove invaluable to those who continue to rely on 2G and GPRS technology. It offers essential support and guidance for individuals who intend to persist with these communication methods. Sending data from an Arduino microcontroller to the ThingSpeak platform using a GPRS module, specifically the SIM800, is a fundamental concept. The crucial aspect is that this communication method operates independently of Wi-Fi, constituting an IoT connectivity solution that relies on GPRS for data transmission. 1 / 2 In this project, LM35 temperature sensor data is being transmitted to the ThingSpeak platform through an Arduino Nano and a SIM800 module. The SIM800 module is leveraged to establish a GPRS connection, facilitating the transmission of data to ThingSpeak at specified intervals. To ensure a reliable connection between ThingSpeak and the hardware, users must configure the SIM800 module to establish a connection with their mobile network. This configuration encompasses setting the Access Point Name (APN) specific to their mobile carrier. It's important to note that the specific AT commands for this configuration may vary based on the user's chosen mobile network provider. For this project, I utilized the services of the network provider '''Airtel''' to establish the connection. Communication between the hardware components, specifically the SIM800 module, Arduino Nano, and ThingSpeak platform, relies entirely on AT commands. To ensure successful project implementation and effectively troubleshoot any issues that may arise, users must possess a basic understanding of SIM800 AT commands. This knowledge is crucial for configuring, managing, and diagnosing the communication process and resolving potential challenges during the project.g potential challenges during the project.)
