Temperature and humidity using the DHT11 sensor and LCD display 1602 with an I2C module and a relevant code.Here I am going to display the temperature and humidity using the DHT11 sensor and LCD display 1602 with an I2C module and a relevant code.Now I have been struggling with this project for like hours now. But at the end I find out I did not have the correct knowledge. So people it is very important to know what you are making. In this case I recommend you to go through the page and not just copy and paste the code.Now, this project uses a DHT11 temperature and humidity sensor with the three pin but you can also use any other sensor the changes in the code should be as per the model. I have used Arduino UNO for this project.

Hello guys, my name is Dayana and I am an electronic engineer, this time I would like to share with you a project that is about a high power DC-DC buck source controlled by arduino.I decided to develop this DC - DC converter since there are many fake high power converters on the market that promise to handle many amps but at the moment they are very fragile and inconvenient.So I developed this very robust and versatile DC - DC source, to be used in any project, where it is required to handle large powers and currents that a common source would not handle, the design of this source is initially intended to be used in non-current currents. greater than 45 amps, and an input voltage of 100 V, (depending on the mosfets and diodes used).Although the idea by itself sounds very crazy, this source works at a frequency of approximately 60 kHz, which is a very considerable frequency for its dimensions, I decided to use this frequency since we can reach efficiency values ??greater than 90% very easily, we will only have to calculate the components correctly to use and put the source to work.Thanks to the current sensor incorporated in the PCB, we will be able to have complete control over the current that circulates through the output of the source, in this way we will vary the duty cycle of the source and by magic we will have a high DC - DC source. Power with current limit ideal for charging lithium batteries or any other type.Finally, I would like to give some guidelines for operation and calculations to take into account for the start-up of this source, first take into account the maximum input voltage and the maximum output current, since based on these data we will have to choose between a mosfet or another for our source, I have to say that in this source the inductor is of vital importance so as not to have a very strong ripple at the output of the source, therefore I recommend using an inductor that easily supports the maximum current output and we will prevent it from saturating and altering the values ??of the calculations made, thanks to all

It was designed as a development board for young developers.And it is designed for high school and middle school students to improve their skills.This is actually also a keychain.

Thanks pcbway :)

Greetings, my name is David Quintero, I am a technician in electronics and communications, and I like to design sound amplifiers.Today I would like to share with you this small, efficient and very powerful class D amplifier design.at the same time I want to recommend that the input capacitors should have a capacity not less than 1000uf since if the amplifier works at maximum power it could have a high current demand, then the capacitors should withstand it to maintain a voltage for the amplifier, Personally, I recommend the use of good power speakers, to be able to use 100% of the power of this great amplifier, additionally I want to highlight that this amplifier has protection against overtemperature, that is, if the amplifier detects a very high temperature, it will protect itself and It will stop working until it cools down, this is very useful since in many occasions we do not have the changes that can occur in the environment, so this circuit is of great help.This small amplifier has a power of 100 W RMS at 3 O, in general this integrated is widely used in very good quality speakers thanks to its efficiency, small size, and great power, I want to make clear the fact that, that a amplifier is class D does not mean that it does not consume, it only means that of what it consumes, it wastes very little, taking this into account we must think of a very good quality power source, to have a clean and powerful sound.I would like to present at this very moment the younger brother of the TPA3116, the TPA3118, which with 60 W RMS of power, becomes an excellent candidate for medium power projects, or failing that we could make a 2.1 system using two TPA3118s for high and medium , and 1 TPA3116 in bridge mode for the bass, designing a high quality and very powerful amplifier, I want to emphasize that this same PCB design works for both the TPA3116 and the TPA3118, since they are pin-to-pin compatible, the only difference important in addition to power, is the way they dissipate heat, in the TPA3116 we will have to use force a heat sink above the integrated one and secure it with screws, on the other hand its younger brother, the TPA3118, dissipates heat by means of a thermal pad that is soldered directly to the PCB, so it will use the PCB as a heatsink and it will not be necessary to use an additional heatsink, this is of vital importance since if the union between the integrated and The heatsink is soldered, it will transfer the heat in a more efficient and fast way, ensuring a long useful life to the amplifier circuit.But not everything is perfect, this implies that the PCB must be designed very calmly, because it will have to be designed with a large area of ​​copper for the correct heat dissipation in it, I would also like to talk about the power supply characteristics of These integrated, which goes from 4.5V to 26V, I personally would not recommend feeding them with more than 22V, this because it is not necessary, since at that voltage it will give its maximum power, if we introduce more voltage, the circuit will lose efficiency, and at the same time it will be more unstable, since we will be working on the maximum limit.To finish I would like to give some brief indications regarding the inductors and filter capacitors that should be used in this design, I recommend using inductors of the best possible quality, since if the inductor becomes saturated it will lose its properties and therefore its nominal inductance will change. which would drastically affect the performance of the filter, so in this case use specialized inductors for class D amplifiers.without more to say I say goodbye, greetings to all and thanks for the support :)

IntroductionPeople are constantly working in order to improve technology and increase the benefit to humanity. To this end, Turkish students with students from all over the world develop their projects in the competition called TEKNOFEST in order to develop aviation in Turkey and to benefit humanity. TEKNOFEST is known as the world's largest aviation and space festival. The TEKNOFEST Aerospace and Technology Festival is organized under the leadership of the Republic of Turkey Ministry of Industry and Technology and the Turkish Technology Team Foundation (T3), which aims at making a Move of National Technology and transforming Turkey into a technology producing society, with the support of Turkey’s major institutions and companies. Our team has been working for the TURKSAT Model Satellite Competition, which is one of the TEKNOFEST competitions, since 2019.Türksat Model Satellite CompetitionTürksat Turkey’s leading technology company, is taking another step to further expand human resources in the field of satellite and space technologies with the organization of the competition.With many universities from Turkey competing in competitions organized abroad, it gives them the chance to share their experience and knowledge with other universities at an event organized in our country.Taking into consideration the high cost of participating in competitions that are organized abroad, students have the opportunity to gain experience in actual space projects with a low budget.During the flight stage, each satellite model is required to send the telemetry information, with the sensor on board, to the ground station. In addition, with every flight, the competing team will have to fulfill special tasks designated by the competition board (pressure, height, sink rate, battery level, photograph and/or video recording, equipment opening, load carrying, ability to send location upon landing and so forth).The annually organized Türksat Satellite Model Competition gives undergraduate and graduate students, who are students of engineering, the opportunity to transform theoretical knowledge into practice and to share interdisciplinary work and experience. In addition to sharing experiences with different university teams, it also provides students the opportunity to set up communication with our expert personnel working in satellite operations, companies from the sector and non-governmental organizations.Our TeamOur team consists of Bursa Uludag University Electrical and Electronics Engineering Students. Our team, which has been working since December 2019, has been working intensely.

Greetings to all, my name is Valentina Ramirez, I am currently a student of electronic engineering at the University of Buenos Aires, today I want to show you my degree project, which is a solar charge controller based on Maximum Power Point Tracker.I decided to develop this project due to the inefficiency presented by the use of chargers called PWM which, due to poor energy management, end up wasting around 25% to 35% of energy produced by solar panels, this is largely produced by the behavior that solar panels have to give their maximum power, which must have a specific voltage and currents in order not to saturate the cells of the panels.but what differentiates a normal solar charger from an MPPT solar charge controller?The answer is found in the objectives of the different solar chargers and how they are executed, as I had already explained, due to the behavior of the solar panels they are not a normal current source, but instead need a voltage and a specific current so that they can work at their maximum power, therefore if we connect a normal DC-DC source, which is also called a PWM charger, it will take out in a very abrupt way and without any control, all the energy it has, producing an abrupt drop in voltage in the solar panel that will ultimately be reflected in solar production.On the contrary, the MPPT charge controller will seek to charge the battery with all the energy that is being generated, but the key is that it does so in a manner controlled by a microcontroller, thus finding the point where the panel voltage drops. abruptly and avoiding it, in order to find the exact point where the voltage and current are maximum to achieve the maximum power.I said a moment ago that MPPT chargers need a microprocessor to control it, so which one will we use? For this design we will use an Atmega328 that will monitor, at high speed, the solar panel voltage, battery voltage, solar panel current and battery current, this microprocessor will be powered from the battery with a DC-DC source 5V based on LM2596Moving on to more technical words, all this will be possible thanks to two resistive dividers that will be sensing the voltage of the batteries and that of the solar panels, additionally we will have two current sensors type ACS712-30A which will be capable of measuring currents of up to 30 amps. and transients of up to 100 amps, the reason for having both the voltage and the current of the solar panel monitored is because the system needs to calculate the current power by varying the cycle of the source PWM to modify the load and find the point full power.The reason for measuring the battery voltage and current is simply to control the maximum values ​​set in the program, which would be the maximum battery voltage and the maximum charging current, highlighting that this system can work to charge any type of battery. battery, already Li-ion, LiFePO4, lead acid, gel, open batteries, among others, of course modifying the desired charging algorithm for charging the different types of batteries, in addition to that the system is open to BMS implementations for example To control the cell-by-cell charge in lithium batteries, thank you for your attention, if you have questions about the design or anything else, write in the comments, I will be happy to answer you.

About the projectI'm studying a master's in electronic instrumentation. In this covid period, we work on a prototype to solve a new contingency in a course of my university (Universidad Nacional Autonoma de Méxco). This prototype for the first time was thinking to joint art and technology and experiment with this area, however, the development of the project will be used to study a relation between the pollution (PM and CO2) on air and the health of the people.Problem: Deterioration of air quality due to the industrial/social process because of the constant demand for the creation of products and services.Response to the problem: The human being is visualized as a mobile being that interacts with an environment that can be toxic or beneficial to his health. In such a way that the human being is seen as a mobile "sensor" that can map the health of a city in relation to pollution (PM particles and/or CO2/CO concentration) in the air.While qualitatively one can feel tired, say that the air is heavy or visualize a cloud of smog in the distance that does not allow to observe the volcanoes near the CDMX, Mexico, the use of a monitor that transforms these expressions to a quantitative form of what we are experiencing in our daily activities in the streets of the city.Thus, a portable air quality monitor that registers the air quality in the zones that an individual travels through in a daily day is a preliminary idea. - Technical: Numerical and analytical visualization of the data as a record of air quality in city halls/colonies. This can be a history of how much the city is degrading or how much the city is improving in a given period. Prototype on printed model3D Model, Top View3D Model, Bottom View-Artistic: Due to the constant rain of data to which we are exposed, many times the numbers are just scribbles on screens which simply move with the movement of a finger. In such a way that to visualize the air quality records we think of a structure like a small heart that has movement and color, both determined by the levels that the mobile being detects, i.e., polluted air means a slow movement or a dark color because the oxygenation of the blood is not done properly (TDB/TBC). This piece is also thought of as a response to "imagining new displays", that is, we always think of screens as a means of visualization for human beings, however, the use of a mobile object that changes color or accelerates or decreases its movement would allow someone to see the effect that in this case the air has on our body.3D model printed

MUR Motorsports is an Australian Formula SAE team competing in the Formula SAE-A competition. Our design team comprises final year Master of Engineering students, with aid from both younger engineering students, as well as students from any discipline wishing to help. Our project is to design, manufacture, manage, and market a single seater, electric race car for the FSAE-A competition.At MUR Motorsports we aim to innovate for the future of the automotive industry. With the progression from internal combustion engine vehicles to electric vehicles that are both more internally connected as well as interconnected the use of customised PCB's are an integral part of our upcoming electric racecar.Having competed in the FSAE-Australasia competition since 2000 and completing the first design cycle of an electric version in 2017 we have experience running in the team, but plenty of potential for further improvements in the new technology. While the 2020 design cycle was fraught with disaster due to lockdowns 2021 aims to advance the design principles and promote testing and validation for future cycles.PCB UsageEssential safety features in the vehicle are amalgamated and processed on custom PCBs which allow for useful signals to be sent to the central control unit of the car (Motec M150). Critical safety of an electric vehicle includes features such as plausibility of brake sensors, isolation testing between high voltage and low voltage systems (400V vs 12V), and fault detection in both the battery management system and control unit.While safety has always been important, and a key feature of the PCBs used on the vehicle the extended design and test cycle has allowed for further data acquisition and validation of design to be a key component of this years’ team. As such the pre-processing of large amounts of sensor data on custom PCBs is of importance. Sensors featuring in the 2021E design include strain gauges for torque measurements, linear potentiometers for the suspension system, and wheel speed sensors for performance improvements in launch control.FutureWhile the E car is still in its infancy the team has begun to shift focus towards the next big step in the automotive industry, automation, and driverless technology. With 18 months of design and simulation behind the autonomous team, incorporation onto the actual vehicle is the next step. Firstly, with a driver in the vehicle taking measurements with cameras and lidars to eventually letting the car free to drive around the track on its own.Sensors processing and amalgamation are hence vital to be completed on a custom PCB. While mechanical actuation also requires signals top be routed and processes, such as the high-pressure piston driven acceleration and braking activation.With limited resources and funding MUR2021E will become MUR2022D and so the design and delivery of the electric racecar will be compatible with post manufacture driverless adaptation.PCBWayWith the help of PCBWay the manufacture of these subsystems will be easily delivered, and the critical pathway of the concept vehicle adhered to. This will also allow for us to perform extensive testing on the vehicle through sensor measurements at track days and on the dynamometer, aiding in the future design of systems and assurance that our vehicle will be ready to win competition!

My project is about a smart speaker.I am going to make this project for my school project. It works as a virtual assistance. We can ask any questions to this. And we can also play music, control the home appliances etc..This speaker contains a raspberry pi 0 w as the CPU. But raspberry pi 0 w doesn't have audio in and out functionality. So for that I going to use a USB sound card. And it contains a 50+50 watts audio amplifier for good music experience. The audio amplifier also made by me. For that I made a PCB circuit in EasyEDA and i am goinh to order the pcbs in PCBway.This is the link to the gerber file and all of the details of this project:- https://drive.google.com/folderview?id=1GTlP8Gy7fXCkRDZ8sw9RJ-aB6YBXZV5_So to make this project I need the sponsorship from PCBway to provide me some beans to redeem a raspberry pi 0 w from PCBway gift shop and some coupons to order the pcbs.

I am going to make a video in youtube about homemade alexa. Alexa is a smart speaker and a virtual assistance.And it is selled by amazon but it cost above 8000.So i am going to build it within 3500 rupees($45).It is 5 times larger than original alexa. It has 40+40 watt speakers and 50+50 watt audio amplifier.This alexa is controlled by raspberry pi 0 w which is a cheapest tiny computer.For the audio input i am going to use USB mic.And for the audio out put raspberry pi 0 w has no audio jack or audio functionality.But the raspberry pi 0 w will give analog audio output from the GPIO pins and there is a problem it will give lot of noise so, for that i am going to make a low-pass filter using some resistance and capacitors.So now we have audio input and output functionality.Now to bring alexa to raspberry pi we need to create a developer account in amazon here https://developer.amazon.com/ .After that we need to install noobs os in raspberry pi. And then by using some commands we can install alexa in our raspberry pi.Then we should complete our circuit and for the power i am using 12volt rechargeable battery because our audio amplifier needs 12volt and to power up the pi i am using 12 volt to 5 volt converter.For the notification ring i am using neopixel strip and epoxy resin art kit to make it translucent.For the enclosure i am going to use 6 inch PVC pipe and for the top and bottom covering lid i am going to use plywood or mdf board.Now our alexa is ready we can ask anything to alexa.If pcbway sponsor for me I will tell some lines about PCBway in the youtube.

My name is Francisco Jose Solis, I am a high-performance computer focused developer and a computing enthusiast.Split mechanical keyboards are a reality nowadays, and much more common than some years ago! Customization of the hardware is an important key factor for gamers, but also for people like me, developers, who take much time of their days close to the keyboard.For the build of my first mechanical keyboard, I decided to go on with the open-source Sofle RGB v2.1, which is a popular split keyboard hosted in Github. I decided to contact the developers of the project as I wanted to ensure that the correct version of the keyboard PCB was sent to production, and for this task I selected PCBWay.PCBWay let me select the solder mask colour and also has a semi-automated process for accomplishing some design rule checks over the design to ensure that it is ready for production. This project contains the needed Gerber files under the repository, ready to go on and attach them to the PCBWay order with default parameters (just ensure you select your desired solder mask colour), the ZIP file is linked here.Currently, the order is accepted and it is ready for being produced, which I am very happy about that. I can't wait to receive the PCB and start building my own custom mechanical keyboard, with which I hope to contribute to the open-source scene by developing some code!Thank you PCBWay for giving me a way to reach my goals and code happier!https://github.com/josefadamcik/SofleKeyboard

Hi!I'm a student on the last year of a technical high school in Buenos Aires, Argentina. This year, if everything goes as planned, I will turn a Technician in Electronics. Me and my group are making a project for this year, involving all the concepts acquired during our stay at school. We are trying to develop a device that would let people, mainly those who have cardiac affection, to measure their own cardiac signal at any time and with a normalized and easy-to-use interface. The idea is to create a compact, ergonomic, practical, battery-powered device that also connects wirelessly to smart devices (mobile phones, PCs) to plot the signal produced by the patient's heart, enabling the user to take a snapshot of that signal and send it to his health professional of preference.Our invention has been induced by the context of the pandemic, in which hospitals are overwhelmed. A device like this one we are presenting would help decompressing the health system, and could also provide the interface for early detection of potentially dangerous cardiac affections.We are applying for the sponsorship because we want to run the necessary tests to generate the prototype of our device, and we need the PCB in order to start doing that. Besides that, our intention is to make the device as affordable as we can, in order to make it accessible to everybody.

Hello. My name is Ivan develop various electronic devices as a hobby. My instagram page @domdevice.I want to make a digital electronic device that will show the current time and temperature inside the room. This project differs from the others in that the silkscreen is applied in the form of two hearts. The large heart has a main 7-segment LED display, and the small heart has fourteen red LEDs. The project I will do on an 8-bit STM8S103F3P6 microcontroller, the temperature sensor will be used by the DS18B20 because it is quite accurate and common. RTC use DS3231.Top side:Bottom side:For main display HT1628 led driver on SPI interface. To control the LEDs, I will use the hardware interface of the SPI microcontroller together with the 74HC595 chips, also known to everyone. I plan to display the time and temperature in a shift mode, and I will try to make different lighting effects for the LEDs. For example, a running light or a smooth switching on and off of LEDs using the PWM timer of the microcontroller. As a power supply for the device, you can use 5V from a USB computer if you use it in the office or almost any charger for cell phones with 5V 1A. You can set the time, change the brightness of the display and the brightness of the LEDs separately in a simple menu. To navigate through the menu, I will use several buttons. In general, this is an electronic device with a romantic theme, as its design is very unusual.I want to develop a project so that it is not just beautiful to look at but also useful to use. There are a lot of ordinary projects of hearts on LEDs, and it will quickly get boring and the clock and thermometer in the shape of a heart can be used daily at home or at work. Moreover it can remind you of the love of a guy for a girl well or vice versa :) it does not matter. In order for me to be able to do this project, I ask the PCBWay company for sponsorship. Let's make our world a little better and brighter together. Sincerely, Ivan.
