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.

About Arjuna EV UGM: Arjuna EV UGM is a Formula SAE from the Gadjah Mada University planning to compete in Formula SAE Japan in the 2022 competition season. Formula SAE is an international competition for university students to develop a formula race car and improve their engineer talents and skills. Arjuna EV UGM is a team of young and talented students building an electric vehicle race car.Powerstage Charging Board: Based on FSAE Rules, FSAE electric vehicle Race Car must have shut down the circuit to keep the car and driver safe from any malfunctions that happen in the car, especially on the Charging condition. Powerstage is part of the shutdown circuit and is used to process data in the form of voltage from several components of the cars, the components are Insulation Monitoring Device and Battery Management System. If Powerstage doesn’t detect any voltage from one of the components, Powerstage will detect it as an error condition for the car and shutdown the High Voltage system on the car. From the experience of previous generations, we realized that a device for detecting error components in our car does not exist, so we decided to design our new Powerstage Charging with a more suitable and efficient system. We Use Data Flip-Flop (D-Flip Flop IC 74HC74) in powerstage charging board to process our data equipped with IC NOT Gate (IC 74HC04), IC OR Gate (IC 74HC32), and IC Frequency Modulator (IC NE555) as pulse source for D-Flip Flop System. The output of this board is an Open-Closed relay that has a Normally-Open system that can open and close shutdown circuit according to FSAE Rules. Words to PCBWay: As a team from the university, we have to build cars at very tight costs and must seek funding independently from companies that are generous to contribute to the development of our education-and-research-based car. If PCBWay were able to generously deigns to give donations in the form of PCB Manufacturing and PCB Assembly, we would be very grateful. These services will greatly assist the research of our team engineers and also contribute to the development of the team as a whole. In return for your kindness, we would be able to put your name and logo on our website, booklet, leaflet, banner, X-banner, and expose you to our followers on social media. Thank you for your consideration and any help you can provide. I look forward to hearing from you soon.

The concept of internet has been accepted since the day it entered human life, but with the technological developments experienced, it has emerged as the internet IoT concept. IoT, which has gained popularity in recent years and is preferred by distinguished researchers.IoT encompasses everything connected to the internet. It is used to describe objects that interact with each other. In simple terms, the Internet of Things (IoT) refers to the tendency to connect all kinds of physical objects to the Internet. The Internet of Things is used in everything from common household appliances such as refrigerators and light bulbs to medical and wearable devices and even smart cities. Specifically, IoT is a system of physical devices that receive and transmit data over wireless networks without human intervention. This is possible by integrating computing devices into objects with the help of sensors.In this project, a system that can be monitored from outside has been created.For example, you are engaged in agriculture.There will be water pump or electrical components that you need to control remotely.These components have been stabilized by using Esp-12 in order to be a system that can be monitored and intervened remotely.Endless thanks to PCBway for their unwavering support as always.

Temperature Board – Arjuna EV Gadjah Mada University About Arjuna EV UGM: Arjuna EV UGM is a Formula SAE from the Gadjah Mada University planning to compete in Formula SAE Japan in the 2022 competition season. Formula SAE is an international competition for university students to develop a formula racecar and improve their engineer talents and skills. Arjuna EV UGM is a team of young and talented students building electric vehicle racecar.Temperature Board: From the experience of previous generations, we realized that a device for detecting battery temperature that meets our needs does not exist. So we decided to design our temperature detection system according to the Formula SAE specifications. The system consists a set of a thermistor, which is negative temperature coefficient (NTC) that functions as a temperature sensor. The data distribution system uses a multiplexer which alternately sends data reading from the NTC to the microcontroller. This system is capable to handle 24 NTC that is measuring 48 battery cells and keep the battery cell safe from over temperature.

I am Sedat a undergraduate electric-electronic engineer student. I recently started RC Airplane hobby and I purpose develop myself in this hobby step by step in systematic manner. Therefore, I ask PCBWay for sponsorship my BLDC & Servo Motor Tester project at very early stage of my hobby as it can be seen by simplicity of my project.One week ago I needed a PWM signal generator to test my new BLDC motor. My aim was to measure thrust data of my motor at different duty cycle values of PWM signal. I made a market search and I found very common servo and BLDC tester which has a potentiometer, input and output ports structure. As my aim was to measure thrust data at different duty cycles, I should know exactly at which duty cycle I am at. However, the products that I found in market does not contain any display. For this reason, I designed a circuit which includes a Arduino Nano, a 16x2 LCD display, 2 potentiometer (one for adjusting duty cycle and the other for LCD contrast setting). Then, I implemented circuit on a stripboard and I verifed it with tests. Right now, I want to conclude this BLDC and Servo Tester project by replacing stripboard with professional PCB because PCB will avoid loose cable contacts and other possible failure reasons when testing motor. Also, replacing stripboard with PCB will gain better and finished project appearence to circuit.I always see sponsorships of PCBWay with my favorite youtube channels on different countries from all around world and I hope PCBWay might be sponsor my project too generously.Best wishes,Sedat

Kind regards, my name is James and I am an electromechanical engineer, this time I would like to show you my PWM speed control for DC motors.This controller is designed to be used in motors of up to 1Kw of peak power, with a voltage of 10V to 70V and a maximum current determined by the mosfets to be used.This controller was developed mainly for the control of high power motors in factories, either for use on a conveyor belt or in any other mechanism that requires maintaining a high power variable voltage, for this project I used a PIC16F1824 as for its manufacturing and operating characteristics made it an ideal candidate for the project.Regarding programming, what I did was that I implemented a small PWM control in the PIC, which would act as an impeller to switch the input voltage through the mosfets at high frequency and achieve a variable voltage at the output of the fountain.So far I have only mentioned the first half of the work, the other half is based on the constant feedback of that output voltage to keep it stable at all times, this part is also done by our beloved PIC, which by means of a resistive divider measures the output voltage and converts it to a smaller voltage so that the pic can measure it but with the same relationship so that it can be interpreted in a proper way.With all the above mentioned, it would only remain to clarify the output filter that this source must have to obtain a decent quality of voltage at the source output, in this case I chose to use an LC filter that by means of a coil and a capacitor will smooth the pulses generated by the mosfets and allow us to obtain a voltage with a minimum ripple.without more to say I say goodbye and greetings to all.

In this bad time we are in, we should stay away from the coronavirus threat as much as possible. However, some of the people who were caught coronavirus and were quarantined in their homes, ignore this threat and escape from their homes and quarantine. Quarantined people pose a huge threat to other healthy people. We thought of many ways to minimize this threat and came up with this idea by combining our skills as electronic engineering students. We are planning to develop a wearable device to follow these people who escape from their homes during the quarantine process, to enable them to spend their quarantine processes in the most efficient way, and to provide them with instant reports to the authorities.I made the revision 2 of project. It include ATMEGA328P microcontroller, SIM808 GSM and GPS module, an SMD GPS Antenna (Linx), touch and proximity sensor, Li-Po charger and protection circuit, Nano Sim Card holder.
