Flux Thumb 2 Good

You don’t need to be an agriculture expert to see the writing on the wall. Current farming methods just aren’t working anymore for most farmers of the world.

There are 2 billion smallholder farms managing fewer than five acres (PDF). They are growing most of the world’s food, but if you have ever visited China, India or any African country, you will have seen the challenges of their reality: yields aren’t what they used to be; climate change, drought and pesticides are getting stronger; and kids are moving to the city. For these farmers, the difference between a good and a bad crop can mean the difference between survival and starvation for them and their families. With even a modest improvement in productivity, lives can be dramatically impacted.  

It’s not just farmers themselves who have a stake in improving the system. Improving agricultural practices has also become a key political issue in many countries, such as India, where Prime Minister Narendra Modi has vowed to double the income of its 200 million farmers by 2022. The government of Vietnam has pledged incentives to help the country’s farmers remain competitive while managing the ever-growing challenge of climate change.

Politicians today can make these promises because they know they are on the cusp of a tech revolution. Low-cost sensors coupled with the internet have created an industry called IoT, or the internet of things. It’s where your hardware can go online and interface with the internet. Most people know Alexa as one of the most common home solutions; self-driving cars are soon to be in the same league.

So what about self-driving farms? Ones where hundreds of sensors listen to the plants and automate critical parts of the process, helping farmers avoid a locust invasion or tumbling prices at the market. Farming solutions can easily monitor soil temperature, water levels and other critical metrics that can be delivered as simple insights to help farmers understand and respond to environmental conditions with precision never before possible. One step further and farms can eventually plant and manage themselves. It’s not a far-fetched dream.

But, when it comes to putting IoT farming technology into practice, there remains a steep challenge. To date, most of the “smart” farming devices that exist are only accessible to big chemical and food corporations. They are siloed technologies in that the data they collect stays in very specific buckets, not to be shared with humankind, ever. These technologies are prohibitively expensive and complicated to use.

There is a reason why analysts label companies like Monsanto, an agriculture behemoth with revenues of $15 billion a year that was acquired by Bayer this year, the “best internet of things” stock investment. Historically, these corporations have held the power of IoT-assisted farming almost solely in their hands, leaving the world’s small-scale farmers to toil away with the same technology they have used for centuries. Megacorps like Monsanto and Syngenta like the deal because this is where so much revenue comes from: the toil and struggles of the small-hold farmer who must use augmented seeds and pesticides to match those seeds. If they don’t “buy in,” there will be no crop.

Individual solutions are popping up everywhere, from smart drip irrigation to optimal fertilizer use, yet they are continually being developed in silos instead of taking into account all potential interactions. Ninety-nine percent of these companies are built to be sold to tech giants. The founders of these companies see an opportunity to greenwash “environmental advancements” for lucrative commercial opportunities. They don’t care about, nor do they see, the big picture.

At Flux Protocol, a team of passionate dreamers and dedicated doers believe that this state of affairs is finally set to change. By developing MICO, a low-cost, open-hardware platform that connects to any quality analog or digital sensor paired with a data encapsulation standard and an incentivization layer for distributed storage and intelligence, the Flux solution will extend the benefits of smart farming to everyone and unlock a future of abundance for all.

The Problem With IoT Farming

As far as IoT farming goes, we have the technology. What we don’t have is a good way to place it in the hands of the people who need it most.

That’s primarily because the lion’s share of smart device development for the agriculture industry is controlled by large corporations. Their goal — understandably enough to them (not to us) — is to leverage IoT devices to improve yields for their own crops, and those of their partners, including big banks and despots. As a result, smallholder or subsistence farmers are left out of the equation.

Small-hold farmers, the very farmers we are rooting for here at Flux, have yet to realize a direct benefit from the IoT revolution as a whole. Existing IoT and blockchain implementations have mostly been centered around supply chain solutions collecting information only after their products have been harvested and left the farm.

Small individual farmers have benefited relatively little from these supply chain solutions. It’s fairly intuitive to use technology to monitor the inventory of a harvested bushel of fruit. It’s much harder, and more expensive, to acquire and maintain IoT sensors that will continuously collect data from their natural systems, like soil temperature, humidity, carbon sequestration, water retention, etc. With Flux, however, these marginalized farmers are able to comprehensively track the process from seed to harvest, or from calf to bull. Not only do these insights help increase harvest yields and reduce input expenditures, Flux-enabled sensors also aid in verifying organic or grass-fed status, earning the farmer significantly more revenue.

MICO and the Democratization of IoT Farming

MICO-based solutions, which are being developed by the Flux team, promise to change this.

You can think of MICO as the Raspberry Pi or military-grade Arduinos of IoT farming. They are small, flexible and extensible electronic boards that serve a variety of purposes and use cases. With 16 inputs and outputs (IOs) that connect any off-the-shelf analog or digital sensor combined with mesh networking capabilities, MICO-based solutions provide any grower with an opportunity to collect natural data points regardless of their location or the size of their growing operation.

Flux MICO#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

By deploying MICO-based devices, farmers can start collecting the exact data points needed to improve their future harvest(s). This could be rainfall levels for a farmer struggling to keep crops irrigated or air temperature for a home grower concerned with optimizing growing conditions in an artificial environment. It could be water salinity levels for an aquafarming site or benchmarking fields for growers trying to determine which part of their land is suitable for the upcoming season.

With a base price of around $25, MICO circuit boards will be affordable for anyone, not just big agricultural companies. As the project evolves, Flux will be creating a number of MICO-based solutions directly aimed at empowering farmers with a variety of different needs.

Developer-Friendly IoT Farming

The power of MICO-based devices goes further than just providing an affordable way to collect natural data. These solutions are just one component of a larger framework that empowers developers to create custom applications that transform natural data into AI-derived insights and value.

Part of that framework is a new data standard that Flux is developing, and which the newly hatched TARA Alliance will be evangelizing to any individual or entity collecting environmental data. By making it easy to share data, the protocol will help farmers build solutions that can help their peers maximize the collective value of the data being captured. On top of its open data standard, the TARA Alliance will promulgate its standard and solutions addressing a wide range of issues that NGOs, governments and academia are seeking to impact.

With this in mind, Flux incentivizes farmers to collect data and build new MICO-based solutions via a native token, FLUX. When collected data is used to produce insights on the platform, the creators of that data will be rewarded in FLUX tokens on a pro-rata basis. Additionally, developers are encouraged to build new applications and solutions on the open market, thanks to bounties hosted on the protocol.

What about farmers or developers who lack the capital to develop novel IoT-assisted farming solutions? Flux has an answer for these people, too. Flux’s Proof of Impact program provides funding to help them get off the ground and further accelerate ecosystem network effects.

In all of these ways, Flux is striving to unlock a future of abundance for everyone. By combining modern IoT farming technology with an incentive to collect data, Flux is positioning our global society to make good on its vision of improving the work of farmers everywhere.

          How To Maintain Connectivity in a Multiboard PCB System      Cache   Translate Page      

By John Burkhert Jr

Bringing a multiboard system together is a chance for the designer to spread their wings. As the circuit spreads, so do the risk of crossed signals. Some of the ways the circuits can get scrambled include:

  • Some connector vendors have clear indications of polarity. Others leave all numbering to the buyer. In the same way, a row of gold fingers will be anything we draw up in terms of pin numbers and signal names.
  • While the physical design typically depicts the orientation of a connector by indicating the location of pin one, rarely is the net that goes on the circuit defined at that level.
  • Each board in the system has a separate schematic, probably drawn up by a subject matter expert that naturally varies from one board to another.
  • A connector can be mirrored to the secondary side, yet we can view it as though we had Superman X-ray vision.
  • A single large connector can have a cable or flexible circuit that mates to it but then splits the larger connector’s signals into several smaller connectors that get distributed all over the system. Each of those branches will have a pin-one of its own but only one of them at the end where everything is collected together.
  • Rogue changes on one card can derail a system.
  • Library inconsistencies and simple mistakes can as well.

Closing all of those potential open loops takes a degree of organization. The system level physical designer is very concerned with everything fitting together. PCB Designers are working within their outline(s) and can also become a bit myopic in that regard. It seems as though we go over these things ad nauseam in the early design reviews when the high-level architecture is being laid out. Then, some bug crops up when we put everything together. What happens? How can we stay on an even keel?

Block it All Out

I don’t mean therapy or hitting your head against the wall. Block Diagrams, Wiring Diagrams, Interconnect Diagrams, Interface Control Diagrams, Outline Drawings, and beautiful 3D renderings all help put the big picture in perspective. They may also be considered too mundane for the critical path and be put off until everything is completely defined. What happens then is that any disconnects get cleaned up in the pre-production run. New boards/cables/flexes are rushed out and all of the expediting and long days go into trying to mitigate the risks before going to mass production. Turning up volume production on something that is mostly tested and verified is one way to live on the edge. So is blindfolded paragliding. Nobody talks about the time their parachute didn’t open. Fewer mistakes in the prototype stage pay the dividend known as peace of mind as we confidently scale up our efforts.

The bigger the job, the more we need to employ risk management in the form of stronger documentation. Nobody does testing and documentation quite like NASA, but the auto industry is really good at supply chain management. When you become part of the supply chain, you quickly become well managed. You get to generate all sorts of documents related to design verification at all levels. Just as you are managed, you become a technical manager to your suppliers as they do for theirs. But I digress.

Creating Order From Chaos, One Step at a Time

The thing is that this level of scrutiny is not as common in the typical consumer hardware setting. Getting your engineering folks to draw up a proper interconnect table may be a stretch. Starting your own “quick and dirty” version is better than nothing and may even prompt the team to fulfill their ideal destiny. We’re after a schematic of schematics. There is a lot of abstraction at this level. A box represents a board, and a list in the box represents the functional connectivity between the various boards.

Image credit: Research Gate - Use more or less detail as required

A system power tree is another important reference point. The number of functions a product has will be a close indicator of the different number of power domains required. Let’s say, for instance, that we have a camera and a display to go with a microphone and speakers to make an Arduino conference room package. All five of those items will want their own power supply even when they are designed for the same number of volts. Scale up to the devices with over 1000 pins and each little area of the device wants a particular power source all its own. They give me an 800-page owner’s manual for the Intel Skylake device. You’d shake your head at that ball-map. It does have an excellent power tree along with the reference design material though.

Life on the Analog Frontier

We got the chance to create a reference design for a Samsung Chromebook Plus. We had the main logic board and a handful of outlying boards. GPS, for instance, needed a quiet area so it could receive the small signals from the satellites. I mean quiet in an electromagnetic sense. The speakers still qualify as a problem because of their magnets. The metal enclosure, the WIFI, the Bluetooth and a number of sensors were all problems.

Coexistence is the name of the game when we try to make all of these disparate functions work together. Simulations will take us a long way, but there are blind spots. You don’t know until you have everything packed into the form factor and turn it all on. Who can forget the time that people wrapped their hands around the upper area of the new iPhone and were told that they were “holding it wrong”? The Pixel phone with its band of non-metal color is an indication of where the invisible connections are taking place through various antennas.

The short answer is that wireless connectivity is the risk that is hardest to manage. For the most part, we try to contain electromagnetic waves. In this case, we’re making them on purpose. The more wireless protocols you have, the more corner cases to explore. Life is better if you only have to tame one radio. Your phone is a war zone of conflicting interests. This laptop was no different. The prototypes were not 100% ready for prime time. The project was pulled together with a few schematic revisions including more filters and regulators; small stuff for the P1 stage except for mis-wiring the battery connector! Mass production followed on with minimal drama. I can say that now, but I was 10,000 miles from where most of the action took place. I know they worked hard too.

Image credit: Author - You’d think we could do something as simple as a battery connector.

The result was thin, light, fast, robust and flexible enough to wrap itself into a tablet, stylus included. Here is a glowing video review of the hardware. Spoiler: the man spent 12 minutes talking about this one laptop and did not have any negatives. Could it be that good? The awards at CES ‘17 were long and strong. This is the ARM processor version that has a lookalike big brother with the Intel SOC. The reviews tend to reflect that this is the lower tier of the Samsung premium convertibles. Working with the outside vendors on the reference designs was interesting.

They provided very detailed .dxf files so we could import geometry directly to the layout. The inner workings of the laptop were rendered over several layers. In a way, that was even better than drawings. The ODM (original design manufacturer) also had the wherewithal to take on the system interconnect review. Between the software models and mock-up hardware, the away team executed a nice product on a three-spin development cycle. Prototypes are the breadboard version without any physical limitations. Pre-production is the first time all of the components are joined in the form factor, and the third cycle is the one that you can still buy. Or not. I have pride in the work but, Samsung doesn’t share anything with me. They are in-house for their designs anyway. We provided a six-layer option to their eight.

Great systems start with solid documentation, strong communication, and trust that everyone is going to hit their mark. The first iteration is to see if things work. The second is to see if it fits and the third has to have 100% of both of those things. In the words of the cold warriors of ancient times, “Trust but verify.” Multiboard systems are expected to be complicated by their nature. The different voltages have to be over- and under-powered in different combinations and over varying temperatures and so on. With all that is expected of these costly systems, it is incumbent upon the designer to take care that the system level connections are fully vetted before the die is cast.

          Writing about a non-sport with a strong sport EC      Cache   Translate Page      
Hi CC, I'm in a bit of a dilemma right now as I write my common app essay, and I'd appreciate a bit of input: I have two hobbies that mean a lot to me: table tennis, and being a maker (if you haven't heard of the term, think of someone who loves spending their time in the garage building all sorts of gadgets with electronics, breadboards, Arduinos, computers, etc.). However, the problem lies in that I've earned multiple awards, national and international as a table tennis player (and I'm also ranked within the top ~300 of boys under 18 in the USA), whereas I don't have anything to show per se as a maker since most of my gadgets have been creative endeavors with household electronics. To clarify, I love both a LOT (I spend around 90% of my time doing one or the other, and the time I spend is about evenly split), and in no way do I have a preference for one over the other. I'm just worried that choosing to not write about table tennis, and instead writing about being a maker will raise questions within the admissions committee about whether I actually liked the sport, and lead them to discredit my accomplishments as a table tennis player. Am I being too paranoid, or am I making a huge mistake? To clarify, I'm not trying to get recruited (strictly for fun!) as an athlete; I'm just applying as a "normal" freshman applicant. Thank you!

USBNinja, así es el malware que se oculta en cables USB y se ejecuta por control remoto#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

Que toda memoria USB desconocida que insertemos en nuestro ordenador puede contener malware es una lección que ya deberíamos tener aprendida. Que incluso en memorias USB completamente borradas puede almacenarse un malware también lo sabemos desde 2014 cuando BadUSB demostró que se insertaba en el firmware del pendrive. Pero quizás sea hora de desconfiar también de simples cables USB como por ejemplo el que utilizamos para cargar un móvil.

Cuatro años después de que los investigadores de SR Labs nos demostrasen cómo almacenaban y ejecutaban un malware desde el firmware de un USB, llega una nueva versión que va un paso más allá para infiltrarse en los equipos informáticos. Lo que en apariencia puede ser un cable USB normal y corriente, alberga en su interior un pequeño control Bluetooth capaz de liberar una carga de datos en el equipo al que se conecta.

USBNinja#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000 El cable "fake" de USBNinja junto al control remoto.

Libera malware desde un mando a distancia o desde la app móvil

Para conseguir insertar malware en estos cables USB, lo que ha hecho el Grupo de Investigación RFID es diseñar un nuevo cable USB equipado en su interior con BadUSB. Por fuera es un cable estándar, sin embargo en su interior, justo en la terminación del cable, se ha añadido una pequeña unidad Bluetooth que espera órdenes para liberar la carga (el malware). El cable funciona como uno cualquiera, permitiendo la transmisión de energía y datos, solo que además viene con ese extra que el usuario desconoce.

USBNinja es el nombre por el que han bautizado a estos cables. Ahora mismo están en proceso de financiación, aunque en el momento de escribir estas líneas casi dobla la cifra pedida para el proyecto. Estará disponible en tres versiones: con cabezal micro USB, con cabezal USB-C y con cabezal Lightning.

Por supuesto que en apariencia por fuera son idénticos a los originales que tratan de imitar, también tienen un voltaje homólogo al de los originales. La diferencia es que como hemos indicado, vienen con la pequeña modificación interna que permite conexión Bluetooth desde fuera. En cuanto a la carga en sí que albergan estos cables es elección de cada uno. Los USBNinja se pueden programar con cargas útiles utilizando Arduino IDE o C.

USBNinja#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000 En el cabezal del USB se encuentra el pequeño transmisor Bluetooth que libera la carga.

Al adquirir estos cables vienen con un control remoto de un alcance de 100 metros que te permite activar la descarga del malware cuando el cable esté conectado a un equipo. O si no, se puede hacer uso de una app en el móvil que también permite ejecutar el malware, pero claro, debe encontrarse a un radio de alcance menor.

El cable deja de ser inofensivo

Si hasta ahora un simple cable nos parecía inofensivo "porque es un simple cable", quizás debamos replantearnos esta idea. Adivinar si el cable puede infectar o no nuestro equipo desde luego no es fácil, por lo que seguramente lo más razonable es desconfiar de cables desconocidos. Por ejemplo utilizando sólo los cables que hayamos adquirido en tiendas (tiendas oficiales y de confianza) y no los que nos presten otros usuarios. O, en casos como los cables USB de Apple, utilizar los que cuentan con certificación MFi que están avalados por la compañía.

Adicionalmente algunos equipos pueden tener diferentes medidas de seguridad para evitar estas intrusiones no deseadas. En el caso de Apple una vez más, de forma automática no permite la transmisión de datos al conectar un cable USB un iPhone o iPad a no ser que ofrezcamos una autorización expresa desde el dispositivo.

«Так, давайте сразу договоримся: вы не собираетесь снимать кино для Голливуда. Даже в Стране чудес утверждается не более пяти процентов от всех сценариев, и только один процент идет затем в производство… Таким образом, вместо всего этого вы собираетесь создать свой собственный Голливуд.»
Эд Гаскель «Снимаем цифровое кино, или Голливуд на дому»


Предисловие


Что, ещё одна погодная станция на Arduino?! Да, ещё одна и, что-то мне подсказывает, не последняя в интернете вещей.


Точно также, как каждый программист обязан написать программу «Hello World!», так и каждый ардуинщик обязан иметь за плечами опыт построения простой или не очень метеостанции.
Уже созданных проектов метеостанций в интернете описано немалое количество, читатель может выбрать любой из них для реализации. Не скрою, я внимательно изучил около десятка подобных проектов и ещё кучу смежных. Поэтому нельзя сказать, что я создал всё с нуля, конечно же я «стоял на плечах гигантов».


Сразу скажу, что в мои планы не входило использование сторонних сервисов для хранения и отображения данных. Хотелось лично пощупать и понять как всё это работает изнутри от начала до конца, от А до Я.


Так что тем, кто хочет быстро склепать нечто из ничего, эта серия статей скорее всего не подойдёт. Проще пойти и купить готовый конструктор с инструкцией по сборке. Профессионалам микроэлектроники тут совсем делать нечего, может быть поржать и вспомнить себя в начале пути.
А вот тем, кто действительно хочет разобраться, я думаю понравится. Возможно материал пригодится в качестве учебного пособия.


Автор проведет вас по запутанным лабиринтам современных технологий интернета вещей. Причём глазами новичка, так как сам им является.

«Так, давайте сразу договоримся: вы не собираетесь снимать кино для Голливуда. Даже в Стране чудес утверждается не более пяти процентов от всех сценариев, и только один процент идет затем в производство… Таким образом, вместо всего этого вы собираетесь создать свой собственный Голливуд.»
Эд Гаскель «Снимаем цифровое кино, или Голливуд на дому»


Предисловие


Что, ещё одна погодная станция на Arduino?! Да, ещё одна и, что-то мне подсказывает, не последняя в интернете вещей.


Точно также, как каждый программист обязан написать программу «Hello World!», так и каждый ардуинщик обязан иметь за плечами опыт построения простой или не очень метеостанции.
Уже созданных проектов метеостанций в интернете описано немалое количество, читатель может выбрать любой из них для реализации. Не скрою, я внимательно изучил около десятка подобных проектов и ещё кучу смежных. Поэтому нельзя сказать, что я создал всё с нуля, конечно же я «стоял на плечах гигантов».


Сразу скажу, что в мои планы не входило использование сторонних сервисов для хранения и отображения данных. Хотелось лично пощупать и понять как всё это работает изнутри от начала до конца, от А до Я.


Так что тем, кто хочет быстро склепать нечто из ничего, эта серия статей скорее всего не подойдёт. Проще пойти и купить готовый конструктор с инструкцией по сборке. Профессионалам микроэлектроники тут совсем делать нечего, может быть поржать и вспомнить себя в начале пути.
А вот тем, кто действительно хочет разобраться, я думаю понравится. Возможно материал пригодится в качестве учебного пособия.


Автор проведет вас по запутанным лабиринтам современных технологий интернета вещей. Причём глазами новичка, так как сам им является.

          Make Your Own Arduino Board – A DIY Tutorial      Cache   Translate Page      

In this DIY Project, I will show you how to Make Your Own Arduino Board using easily available components and a very simple build process. Using this approach, you can make a custom Arduino Board that suits your needs.

How to Make Your Own Arduino Board Image 1

Introduction

If you are following ElectronicsHub for some time, you will notice that we love Arduino. Not only it is a simple and easy to use platform, but also there is a huge community of users, developers that make frequent and significant contribution (either to hardware or software).

Using Arduino, you can implement simple LED Control Projects to complex Robots like these Bluetooth Controlled Robotic Arm and Line Follower Robot.

It is well and good as you can simple buy an Arduino board (an original one or a cloned one) and program it using the Arduino IDE. But what if you want to have a customized Microcontroller Board specifically for your project but still retain the important features of Arduino? Wouldn’t that be nice.

Well, in this project, I am going to show you how to Make Your Own Arduino Board by explaining the steps and process that I went through to build my custom Arduino Board.

Why Do You Need to Make Your Own Arduino Board?

Arduino Board (consider Arduino UNO as an example) provides a wide range of features like Digital Input / Output Pins, Analog Input Pins, PWM, Interrupts etc. out of the box. One of the main important features of Arduino is the USB Interface.

Simply connect your Arduino Board to the computer using an USB cable, open the Arduino IDE, write a simple code, upload it to Arduino. It is as simple as that.

But to interface with peripherals, say a Potentiometer or a Motor, you need to connect then using jumper wires.

If you some how want to integrate small components like POTs or Motor Drivers onto the Arduino Board itself to avoid the dangling wires, if would look nice and tidy and can help you go commercial (to sell your product).

The only way is to Make Your Own Arduino Board. Even if you are not building an embedded system around Arduino, you can still Make Your Own Arduino Board just for the sake of making it testing your custom design.

How to Make Your Own Arduino Board Image 7

Prerequisites to Make Your Own Arduino Board

Before taking a look at the actual process of making your own Arduino Board, you need to keep a few things ready. The first important thing is the design of the board. If you have a custom design on mind, make use of any schematic capture software and start working on the design.

The second important thing is specific to this project. To reduce the complexity, I haven’t used the USB Connector with USB – to – Serial Convertor IC. Instead, I will be using the SPI Pins of ATmega328P (the microcontroller on Arduino UNO) to burn Bootloader, which is a one-time job, as well as upload a program.

So, take a look at this tutorial on How to Burn Bootloader to ATmega328, which gives a comprehensive information on burning Bootloader as well as the program.

Circuit Diagram of Your Custom Arduino Board

As I have mentioned earlier, the first and important part to Make Your Own Arduino Board is to have a clear idea on the design of the board. This step starts with building the circuit. The following image shows the circuit of the Arduino Board in my project.

How to Make Your Own Arduino Board Circuit Diagram

NOTE: To view a larger image, right click on the above image and click on “Open image in new tab” option.

Components

  • ATmega328p Microcontroller IC
  • 28 Pin IC Holder
  • 16 MHz Quartz Crystal
  • Capacitors – 2 x 22pF, 100nF, 2 x 47µF
  • Resistors – 2 x 330Ω, 470Ω, 1KΩ, 2.2KΩ, 7.5KΩ, 2 x 10KΩ, 30KΩ
  • LEDs x 2 (Red and Green)
  • Push Button (for Reset)
  • Slide Switch (ON / OFF)
  • 5V Regulator (7805)
  • 3.3V Regulator (LD33V)
  • 10KΩ Potentiometer
  • 1N4007 Diode
  • IRF540N MOSFET
  • Miscellaneous (Screw Terminal, Male Headers, Female Headers, 2.1mm Power Jack, Perf Board)

NOTE: These Components are specific to my design and your list of components may be different.

Make Your Own Arduino Board

If you are ready with the circuit diagram (double check every connection), you can proceed to Make Your Own Arduino Board. At this point, you can design the PCB Layout using any software and make your own PCB as shown in this tutorial: How to Make your Own PCB.

But to keep things simple, I have decided to go old school. Use a Zero Board and start building the board from scratch using loads of solder. I know this is not a reliable technique but I felt this is sufficient for a small tutorial.

May be in the future, I will design a semi-professional PCB and make a better-looking custom Arduino Board.

Important Features of My Custom Arduino Board

Now, I will point out some of the important features of my Arduino Board.

How to Make Your Own Arduino Board Features

  • I have included a MOSFET to drive a Motor and it is connected to D5 so that there is a chance of PWM Control as well.
  • For Analog Input A0, I have connected a 10KΩ POT.
  • Coming to Analog Input A1, I have connected a Potential Divider consisting of 30KΩ and 7.5KΩ Resistors to directly measure input voltage up to 25V.
  • The TX and RX Pins are provided with an option of 3.3V Logic.
  • There is slide switch to turn ON and OFF the Arduino Board.
  • I have included two LEDs: One is a Power ON LED and the other is a User LED connected to D13.
  • All the Analog and Digital (as well as the power) headers come with both Male and Female headers.
  • A separate 4-pin female header for programming.
  • In the power pins, I have provided options for 3.3V, 5V as well as 12V.

Conclusion

A DIY Project on How to Make Your Own Arduino Board is implemented here. Using a similar approach (and perhaps with a proper PCB) you can make your own Arduino Board to fulfil your custom project requirements.

Заоконный датчик. Железо


Надо сразу признать, что первая версия заоконного (удаленного) датчика получилась не совсем удачной в плане электропитания и энергопотребления. Как я уже писал, у меня под рукой был только модуль Arduino Pro Mini на 5 В. И я использовал Ni-MH аккумуляторы.


При том, что я подсоединил ещё и солнечную батарею вся конструкция у меня проработала автономно около 25 дней. Очень отрицательно на ёмкость аккумуляторов повлияли низкие, часто отрицательные температуры на улице конца зимы.


Чтобы у вас всё работало гораздо дольше, произведите следующие замены:


  • Купите Arduino Pro Mini на 3,3В
  • Используйте Li-ion аккумулятор типа Panasonic NCR18650A на 3,7 В, 2 шт. примерно за $14 на 3100mAh. Можете попробовать CR123, CR123A батареи. И помните о том, что 9В батарея (типа "Крона") плохой источник питания.

          Unlocking the Full Potential of IoT Farming - [BTC Media Sponsor]      Cache   Translate Page      

Unlocking the Full Potential of IoT Farming - [BTC Media Sponsor]You don’t need to be an agriculture expert to see the writing on the wall. Current farming methods just aren’t working anymore for most farmers of the world.There are 2 billion smallholder farms managing fewer than five acres (PDF). They are growing most of the world’s food, but if you have ever visited China, India or any African country, you will have seen the challenges of their reality: yields aren’t what they used to be; climate change, drought and pesticides are getting stronger; and kids are moving to the city. For these farmers, the difference between a good and a bad crop can mean the difference between survival and starvation for them and their families. With even a modest improvement in productivity, lives can be dramatically impacted.  It’s not just farmers themselves who have a stake in improving the system. Improving agricultural practices has also become a key political issue in many countries, such as India, where Prime Minister Narendra Modi has vowed to double the income of its 200 million farmers by 2022. The government of Vietnam has pledged incentives to help the country’s farmers remain competitive while managing the ever-growing challenge of climate change.Politicians today can make these promises because they know they are on the cusp of a tech revolution. Low-cost sensors coupled with the internet have created an industry called IoT, or the internet of things. It’s where your hardware can go online and interface with the internet. Most people know Alexa as one of the most common home solutions; self-driving cars are soon to be in the same league.So what about self-driving farms? Ones where hundreds of sensors listen to the plants and automate critical parts of the process, helping farmers avoid a locust invasion or tumbling prices at the market. Farming solutions can easily monitor soil temperature, water levels and other critical metrics that can be delivered as simple insights to help farmers understand and respond to environmental conditions with precision never before possible. One step further and farms can eventually plant and manage themselves. It’s not a far-fetched dream.But, when it comes to putting IoT farming technology into practice, there remains a steep challenge. To date, most of the “smart” farming devices that exist are only accessible to big chemical and food corporations. They are siloed technologies in that the data they collect stays in very specific buckets, not to be shared with humankind, ever. These technologies are prohibitively expensive and complicated to use.There is a reason why analysts label companies like Monsanto, an agriculture behemoth with revenues of $15 billion a year that was acquired by Bayer this year, the “best internet of things” stock investment. Historically, these corporations have held the power of IoT-assisted farming almost solely in their hands, leaving the world’s small-scale farmers to toil away with the same technology they have used for centuries. Megacorps like Monsanto and Syngenta like the deal because this is where so much revenue comes from: the toil and struggles of the small-hold farmer who must use augmented seeds and pesticides to match those seeds. If they don’t “buy in,” there will be no crop.Individual solutions are popping up everywhere, from smart drip irrigation to optimal fertilizer use, yet they are continually being developed in silos instead of taking into account all potential interactions. Ninety-nine percent of these companies are built to be sold to tech giants. The founders of these companies see an opportunity to greenwash “environmental advancements” for lucrative commercial opportunities. They don’t care about, nor do they see, the big picture.At Flux Protocol, a team of passionate dreamers and dedicated doers believe that this state of affairs is finally set to change. By developing MICO, a low-cost, open-hardware platform that connects to any quality analog or digital sensor paired with a data encapsulation standard and an incentivization layer for distributed storage and intelligence, the Flux solution will extend the benefits of smart farming to everyone and unlock a future of abundance for all. The Problem With IoT FarmingAs far as IoT farming goes, we have the technology. What we don’t have is a good way to place it in the hands of the people who need it most.That’s primarily because the lion’s share of smart device development for the agriculture industry is controlled by large corporations. Their goal — understandably enough to them (not to us) — is to leverage IoT devices to improve yields for their own crops, and those of their partners, including big banks and despots. As a result, smallholder or subsistence farmers are left out of the equation.Small-hold farmers, the very farmers we are rooting for here at Flux, have yet to realize a direct benefit from the IoT revolution as a whole. Existing IoT and blockchain implementations have mostly been centered around supply chain solutions collecting information only after their products have been harvested and left the farm.Small individual farmers have benefited relatively little from these supply chain solutions. It’s fairly intuitive to use technology to monitor the inventory of a harvested bushel of fruit. It’s much harder, and more expensive, to acquire and maintain IoT sensors that will continuously collect data from their natural systems, like soil temperature, humidity, carbon sequestration, water retention, etc. With Flux, however, these marginalized farmers are able to comprehensively track the process from seed to harvest, or from calf to bull. Not only do these insights help increase harvest yields and reduce input expenditures, Flux-enabled sensors also aid in verifying organic or grass-fed status, earning the farmer significantly more revenue. MICO and the Democratization of IoT FarmingMICO-based solutions, which are being developed by the Flux team, promise to change this.You can think of MICO as the Raspberry Pi or military-grade Arduinos of IoT farming. They are small, flexible and extensible electronic boards that serve a variety of purposes and use cases. With 16 inputs and outputs (IOs) that connect any off-the-shelf analog or digital sensor combined with mesh networking capabilities, MICO-based solutions provide any grower with an opportunity to collect natural data points regardless of their location or the size of their growing operation.By deploying MICO-based devices, farmers can start collecting the exact data points needed to improve their future harvest(s). This could be rainfall levels for a farmer struggling to keep crops irrigated or air temperature for a home grower concerned with optimizing growing conditions in an artificial environment. It could be water salinity levels for an aquafarming site or benchmarking fields for growers trying to determine which part of their land is suitable for the upcoming season.With a base price of around $25, MICO circuit boards will be affordable for anyone, not just big agricultural companies. As the project evolves, Flux will be creating a number of MICO-based solutions directly aimed at empowering farmers with a variety of different needs. Developer-Friendly IoT FarmingThe power of MICO-based devices goes further than just providing an affordable way to collect natural data. These solutions are just one component of a larger framework that empowers developers to create custom applications that transform natural data into AI-derived insights and value.Part of that framework is a new data standard that Flux is developing, and which the newly hatched TARA Alliance will be evangelizing to any individual or entity collecting environmental data. By making it easy to share data, the protocol will help farmers build solutions that can help their peers maximize the collective value of the data being captured. On top of its open data standard, the TARA Alliance will promulgate its standard and solutions addressing a wide range of issues that NGOs, governments and academia are seeking to impact.With this in mind, Flux incentivizes farmers to collect data and build new MICO-based solutions via a native token, FLUX. When collected data is used to produce insights on the platform, the creators of that data will be rewarded in FLUX tokens on a pro-rata basis. Additionally, developers are encouraged to build new applications and solutions on the open market, thanks to bounties hosted on the protocol.What about farmers or developers who lack the capital to develop novel IoT-assisted farming solutions? Flux has an answer for these people, too. Flux’s Proof of Impact program provides funding to help them get off the ground and further accelerate ecosystem network effects.In all of these ways, Flux is striving to unlock a future of abundance for everyone. By combining modern IoT farming technology with an incentive to collect data, Flux is positioning our global society to make good on its vision of improving the work of farmers everywhere.
