Who we are, and what we're doingWe are two mechanical engineering students at Tufts University. As part of a project with our university robotics club, we are working on making strong, fast, accurate, and reliable robot actuators. We were inspired by robots like Spot and Atlas by Boston Dynamics, the Unitree A1, and the MIT Mini-Cheetah. This work is broken into two parts: a custom actuator with a 6:1 planetary gearbox called the OrbitDrive, and a custom-designed motor controller board: Daedalus.Project DescriptionAs mentioned above, our project is broken into two parts, but they come together seamlessly to make a state-of-the-art robotic actuator. This actuator is as small and powerful as we can make it. The Daedalus motor controller is perfectly designed to complement the mechanical design, and fits directly behind the motor. Using an integrated magnetic encoder, the Daedalus board can provide extremely precise position control to the motor. It runs at 24V and is capable of supplying up to 30 amps to the motor when required. It uses the CAN bus communication protocol, and accepts power via one of two XT30 plugs on the bottom of the board. It is designed to be fully daisy chained, with in terms of power and data to reduce the number of wires that go to your main robot controller. With it's on-board STM32 microcontroller and 168 MHz clock speed, the Daedalus Motor Controller can also perform blazing fast calculations to help offload computation from the main robot computer. It comes equipped with an SWD breakout, and Micro USB port for programming and debugging.This project is fully open source, with full build instructions and a detailed bill-of-materials coming soon.Daedalus ControllerOrbitDrive with the Daedalus ControllerFuture PlansIn the future we plan to develop the firmware to run this board and optimize it for use with our custom actuator. As with the hardware, this will be fully open-source and open for hacking and modifying to fit other projects. We intend to develop a version 2 of this board that we hope will be smaller, and capable of supplying even more current at peak.Words to PCBWayWe are hoping PCBWay will be able to help us by sponsoring our Daedalus Motor Controller board. We have put countless hours in the careful design, and re-design of this board to make full use of PCBWay's manufacturing capabilities. We intend to use the assembly service to fully assemble all the surface mount components, add our Micro-USB port, and mount our magnetic encoder to the back of the board. We want to thank PCBWay for having such an easy and inviting sponsorship program for universities and students.

This is an rc controller board based on arduino pro mini.I made this because I couldn't find any rc receivers based on arduino pro mini.This is a basic board.First, we need to solder the pin headers of the Arduino board. A convenient way to do that is to use a breadboard to stick the pin headers in it and so the board will stay firmly in place while soldering. As I said earlier, depending on your board, the pins might vary a bit, so keep that in mind when soldering them.Also, there are some Ground pins that we need to leave free as there are some traces running on the PCB under them. Once I soldered the Arduino board, I cut the excess length off the pins.Next, I placed all other pin headers in place. We need both male and female pin headers, or it’s actually up to you what pin headers you will choose to use. However, it’s a good idea to use male pin headers for the digital channels as the servo motors and the ESC connections are female, so we can easily connect them.The voltage regulator is a surface mount component so I used some Blue-Tack adhesive to hold it in place while soldering. Lastly, once we solder the two capacitors in place, we can attach the NRF24L01 module to the appropriate pin headers.Depending on the application, or the range that we need, we can use either the normal module with the onboard antenna or the one to which we can attach a bigger antenna and can achieve wireless communication of up to 700 meters in open space. So that’s it, our Arduino RC Receiver is now ready and we can use it for anything we want.

About the TeamThe EPFL Rocket Team is a project composed of students from the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland.It aims to build a rocket capable of ejecting a scientific experiment as part of the Spaceport America Cup, the largest student rocketry competition in the world. This competition takes place every year, in June, in New Mexico (USA) and is followed by references in the aerospace industry such as Boeing, Blue Origin and Virgin Galactic.The teams lining up at the competition in 2018 What we have achievedLast summer, after only two participations, we finished in the top 10 of our category on 52 teams with Project Eiger, and the year before we won the "Jim Furfaro Award for Technical Excellence" with Project Matterhorn, a prize awarded to a team on 124 participants who demonstrated the best mastery and understanding of the technologies developed in the rocket.The Eiger rocket at its presentation at EPFL, Lausanne, SwitzerlandThe EPFL Rocket Team in the New Mexico desert for the competition in 2019The Eiger rocket launched at the competition in 2019The Bella Lui Rocket This year, we want to build upon those success with "Project Bella Lui", a 4-meter, 40-kilogram rocket that will be propelled to an altitude of 10,000 feet (3048 meters) with a hybrid engine developed by students from the team, before ejecting an experiment: a life sensor analyzing the behavior of yeast in harsh conditions. The success of this ambitious project depends on the support of our sponsors. We are already collaborating with companies such as RUAG Space, Sauber Aerodynamics, Maxon Motors, and APCO Technologies, which finance us and advise us on the technical aspects of the project.Our partner are benefiting from an important visibility on the EPFL campus. We participate in many events on the campus (Association Week, Technology and Innovation Fair and Forum EPFL at the Swiss Tech Convention Center, EPFL Open days and other events on campus) where our sponsors are brought forward. We also attend many events outside the campus in Switzerland and abroad (Rockets launches, ESA Open Day…). Supporting this project is also a great way to reach passionate, talented and ambitious engineers.

IntroductionAs wildfires burn, a variety of airborne particles and harmful gases are released into ambient surroundings. Pollutants, including fine particulate matter (PM), volatile organic compounds (VOCs), nitrogen dioxide (NO2), sulphur dioxide (SO2), and ozone (O3), contribute to the poor air quality experienced in areas adjacent to wildfires. Perhaps the most relevant pollutant that is emitted by wildfires is fine particulate matter, specifically that measuring less than 2.5 μm in size (PM2.5). Reports have shown that in the vicinity of the wildfires, dangerous levels of PM2.5 are present, surpassing the World Health Organization's maximum recommended daily exposure of 25 μg/m3 by a factor of 10. The incredibly small nature of these particles means that it can be easily inhaled deep into the lungs, causing lasting damage. The NeedImprovements to air quality monitoring have the potential to contribute to resilient infrastructure and inclusive, safe, and sustainable cities by providing the situational awareness needed to adapt quickly to health concerns. Poor air quality continues to have significant health and economic impacts on those living in wildfire-prone regions, particularly in urban areas. As a result, a method to educate and inform people about the effects and onset of poor air quality conditions is required. While some solutions exist, they are generally not portable and if they are they do not provide a wide range of pollutant measurements.The Solution: Project CanaryA University of Waterloo Undergraduate Mechatronics Engineering 3rd Year ProjectProject Canary is a compact, connected, portable air quality monitor that is capable of detecting dangerous particulate matter and hamful gasses. It can indicate measurements directly though LEDs and a buzzer, but will also connect to the users phone over BLE for more in-depth analysis and to upload data to the cloud. Below is a sketch of what the completed device may look similar to.The device will be powered by an internal rechargeable battery, which will be charged via the USB port on the side. It will contain a light-scattering particulate matter sensor, and a PCB with hardware to control and read from this sensor, as well as process measurements and communicate over BLE with a mobile phone. The device also contains an amperometric gas sensor, for measuring toxic gasses like O3, NO2, and SO2, as well as a MOS gas sensor for detecting harmful VOCs.

Hello Everyone,I have a designed a PCB to be used as a battery monitor for IoT applications. I am on a team of four engineering students from the University of Kentucky and will be using this in an electric boat for the promoting electric propulsion (PEP) competition this Summer. Please reach out if you would like to help me with the PCB fabrication process or would like to see my schematic and PCB files. I am currently using KiCad for the development process. As of right now we have all of the components and only need to fabricate the PCB. I highly encourage you to visit slide number 18 and beyond within our critical design report to see how this monitoring system will play a key role in the overarching design of the watercraft!Thanks,TannerUniversity of KentuckyComputer Engineering

Valkyrie, the new electronics system: RICHARD MK IIIOur rocket, Valkyrie, is a bi-liquid rocket that uses isopropyl alcohol as fuel and nitrous oxide as oxidizer. Our engine is 3D printed in steel and has coolant channels around the chamber, so the fuel is cooling it down while operating along with optimizing the burn of the fuel. The Valkyrie rocket has an upgraded version of the Dragonfly’s “the Stack” - electronics named “The Rack” - due to the new design involving board placement like that of slot-in RAM in a computer. The Rack (Electronics)In our new rocket, Valkyrie, we will use the same flight computer we built for the previous rocket, Dragonfly, but with some upgrades. This flight computer will be put together in a rack, like RAM modules slid into a motherboard supported in each side and locked into place with a locking mechanism, so it does not fall out from vibration during operation of the rocket. Our rack has the following boards each with specific functionalities; Template boardAll PCBs in the Rack are based on a template design; an STM32g4 microcontroller with power management, external flash, external EEPROM, CAN transceiver, barometer, and IMU. This allows every board to log data, store configuration files, and communicate with the rest of the boards on the CAN bus.Telemetry boardThe telemetry board is responsible for transmitting in real time data, about the rocket, to the ground station. Among this data, there is information about the rocket's speed, attitude and location. For this purpose, the telemetry board comprises a GPS module and three LORA transceivers connected to the on-board antennas. Thereupon, there is also a similar board on ground used to receive and decode the transmitted data. Finally, the temetry board is integrated in The Rack and communicates with the other boards via CAN bus. Actuator boardThe Actuator board controls the different Servo boards located in different places in the rocket. The board sends out PWM signals for controlling the servos, enable signals to turn on power for the servos, and gets feedback from the servo board. Main boardThe Main board acts as a “leader” of the Rack, making decisions on what measurements need to be taken and which actions should be taken. It does this by requesting data from the other boards on the CAN bus, or telling other boards what to do. The Main board also has an RS422 transceiver, which is used for communication with Mission Control while the rocket is still on the launch rail pre-flight.Pressure boardThe Pressure board measures 7 different pressures in the rocket, in both the engine and the rest of the fluid system. It also reads the measurements from the level sensor, which shows how much oxidizer is left in the tank.Temperature boardThe Temperature board measures 8 different temperatures in the rocket.Power boardThe Power board provides power to the Rack on two separate grounds. It houses three switch-mode power supplies; a logic 5V line, a power 5V line, and a power 15V line. It is also responsible for switching on three different cameras in the rocket right before flight. Additionally, the power board measures the battery voltage and current output of all batteries in the rocket, as well as the power consumption of it’s switch-mode power suppliesBackplaneThe Backplane is exactly what it sounds like, a backplane for communication between each board in the flight computer. The backplane connects to each board using a slot in connector, similar to the well known PCI-E 4x slot, providing more than enough connection pins for each board. This enables super fast board changes in case of a malfunction, hardware failure etc. Besides handling all communication between flight computer boards, the backplane also connects the flight computer to the rest of the rocket, eliminating the need for multiple connectors on each board. Servo boardControls one pair of servos using PWM signals supplied by the Actuator board. It is supplied with 12.5V from a LiPo battery which is converted down to 7.4V for driving the servos and 5V for powering the on board PWM buffer. An enable signal triggering a current toggle allows for quick shutdown in case of failures.BMSBMS (Battery Management System) is a 2A charging and monitoring board for various 12V LiPo batteries around the rocket, one per battery. Several batteries can charge from a 24V bus.IgnitorThe ignitor board is a crucial part of the rocket, since the ignition of the rocket is controlled on this board. The board is supplied with a 12.5V LiPo battery and takes in 3 signals for ignition: Rocket_ready, Rocket_ARM and MC_Ignite. All 3 signals have to be set high in order to generate the ignition and are controlled through an AND gate with diodes. The current generated for ignition is done by a LM1084 which outputs 1.5V and 4A. 2 relays are added for safety features, as a mechanical shut off. 5 LED’s are added for debugging to see if the signals are activated. MiddlemanThe name of the middleman board stems from its literal function, being between our COTS (Comercial Off The Shelf) flight computers, and the servos executing the recovery operations. It is a competition requirement that the flight computers that deploy the parachute be commercial, and not made by us. This introduces a problem, as our parachutes are deployed by servoes, and the flight computers output either a high or low signal, and thus cannot control servos. This is where the middleman comes into play, receiving data from the flight computers, and generating a PWM signal that moves the servos accordingly. Apart from controlling the servos, the board has feedback features to verify whether the servos have actually moved when the signal is sent, and whether the corresponding parachute has deployed. All this is communicated to the central “Rack” flight computer.Launch rail and keybox boardTwo additional PCBs will be designed; a launch rail board and a keybox board. The keybox board sits inside a little box with a keyhole at Mission Control, roughly a kilometer away from where the rocket is to be launched. A key can be inserted in the keybox, and turned to three positions: OFF, ARM, and IGNITE. The keybox also sends RS422 data along a kilometer long cable to the launch rail board, which sits in a launch rail cabinet, which is mounted on the side of the rocket’s launch rail.Support from PCBWay would be an enormous help towards reaching our goal in time! Our next rocket is scheduled to launch in October 2021 from Portugal and here, we will hopefully break the world record for height reached by a student built bi-liquid rocket!

As METU Göksat Space Team we are planning to participate the 2021 Teknofest Model Satellite Competition held in Turkey.(https://www.teknofest.org/en/yarisma-detaylar-16.html)This project is a model satellite designed to have 2 components, which are payload and carrier.Carrier will protect the payload which contains the electronic and mechanical parts.In the course of the competition, the model satellite will reach between 500-700 meters and will be released.It will descend at the rate of 10-14 m/s until an altitude of 400m with a passive landing system.After 400 meters payload will detach from the carrier and complete the landing with a constant velocity between 8-10 m/s using an active landing system.Within this period payload will send a data-package comprised of sensor and telemetry data to the ground station while broadcasting a snapshot, and it will store the same information on itself.Also, a 1 MB video provided by TÜRKSAT will be sent to the satellite from the ground station. (Pictures show the printed circuit boards from the side and the top.)

TU Wien Space TeamThe TU Wien Space Team is a student led group with emphasis on aerospace engineering at the TU Wien, Vienna, Austria. Our focus lies on the design of experimental rockets, rocket engines and mini satellites. Our projects are meant for civil use only.Test StandFor future development of rocket engines of the size necessary for the suborbital rocket Houbolt, a larger test stand is in development. To have abundant capacities for future projects, the test stand is constructed to handle a thrust of up to 24kN, which makes it the largest of its kind ever to be used in Austria. For maximum flexibility it can not only be operated with the propellant combination Ethanol/Nitrous Oxide which is planned for the Houbolt rocket, but also with any other usual combination like e.g. Ethanol/LOX (liquid Oxygen). For more flexibility regarding the test location, the frame is mounted on a trailer which enables repair and maintenance work to be done at the workshop and reduces the requirement for the test location immensely. More information: https://spaceteam.at/ts03-24kn-franz/?lang=enI/O BoardHas 12 channels that can be configured as various types of input (Voltage, Current, Resistive Bridge) or output (Low Power, High Power). Communicates via two CAN FD busses with other boards and a server. Used 8x on the test stand for reading out many pressure and temperature sensors and controlling solenoid valves. Load Cell BoardHas 8 high resolution differential analog input channels for reading out load cells. Communicates via two CAN FD busses with other boards and a server. Used 2x on the test stand for thrust and tank weight measurement.Servo Control BoardControls a high torque RC servo and measures position feedback and current consumption. Communicates via two CAN FD busses with other boards and a server. Used 3x on the test stand for ball valve actuation.https://spaceteam.at/txvbase11/?lang=en

IntroductionOpenLF stands for "open led and fan". Its a controller that will monitor led current(max current 6A) and control brightness. It also includes a independent 3 Wire fan controller IC with option to read RPM and adjust the fan's speed. In the design one status led and a button is also present which can be configured for future purposes. An additional i2c header is also present which can be further extended to use external 2 wire peripherals like an OLED. The fan speed and led brightness can be externally set by two potentiometers.MicrocontollerThe heart of the project is Attiny1614 which can be programmed with UPDI Programmer. The source code of the programmer can be found here. The arduino core for the MCU can be found here. It has 16384 bytes flash, 2048 bytes RAM and 256bytes EEPROM on-board which makes it suitable for this project. The major reasons for choosing this IC over others are as follows:Cheap,small footprint and available in solder-friendly SOIC packageinternal clock configuration support upto 20MHz.Major PeripheralsMAX6650 - The fan controller ic MAX6650 which is connected to the MCU via I2C. It can regulate and monitor the speed of 5VDC/12VDC brushless fans with built-in tachometers. They automatically force the fan’s tachometer frequency (fan speed) to match a pre-programmed value in the Fan-Speed Register by using an external MOSFET or bipolar transistor to linearly regulate the voltage across the fan.INA226 - It is a current shunt and power monitor with common-mode voltage upto 36V controlled by I2C. It has programmable conversion times for both the shunt voltage and bus voltage measurements which makes it easy to be configured to optimize the available timing requirements in a given application. This is used to measure the current consumed by the attached led and thus provide feeback loop to the mcu to adjust PWM accordingly.ApplicationThe controller can be used in multiple led applications where DC side dimming is required for example, adjusting brightness of a led back-lit panel used in photography and videography. User can get details of power consumption of the led displayed on OLED. The external header for UART can be used for debugging or talk to other wireless microcontrollers for remote operation.Please note, this is a initial release and may not have enough features.Further improvements may include wireless mcu like ESP8266, efficient buck converter for lowering power loss, etc.

My name is Franco I'm from Mexico and I be 20 years old, I'm studying industrial engineering in the Universidad Regiomontana from Monterrey, I enjoy creating and innovate, I'm interested specially in aerospace projects, but every subject related to science is interesting for me, I love also the music production and the midi instruments, and also I like the subjects related to botany.Project description:I'm creating a new project related to botany, In my country it is very difficult to germinate some types of seeds because we have a lot of temperature changes in my city, it can be cold or warm immediately, so it is very difficult to control the humidity and temperature in this part of the country, for that reason I decide to create this project, Basically I will program everything with Arduino, I will control the cold temperature with peltier cells and the heat with a thermal lamp, it will also have an autonomous irrigation system that will provide its own water based on the condensation of the peltier cells so basically you would not need to water either.List of components:Peltier cellswater pompArduino green housethermal lampsome screwsPCB boardsSolar panel 12 volt batteryI would like to acknowledge that pcb way is not just a company as I thought, I am finding out about the support they give to young people in their projects, I do not expect to receive all the support, but having the time to support the creation and development for the projects for young people, make them have a value more than any company.Finally, I want to comment that this project will be recording for YouTube, in case of being accepted to continue with this project you will receive a space for your sponsorship, thank you.

I was always amazed at these small devices. My dad uses these to log into his work laptop, I couldn't understand how can it generate a code without being connected to any network.I fired up google and tried to search about it, and surprisingly it used a pretty amazing concept. It had a shared key with the server and then it did some computation on the shared key and current UTC time to get a 6-digit number. So, the remote device just had to be accurate at timekeeping. It uses a algorithm called TOTP (Time based one time password), it's been standardized and there's no point in getting into the details, here's the standard if anyone wants to take a look. You can read this article on freecodecamp.org for more layman-ish approach to the whole algorithm.First PrototypeComing back, so I decided to implement this using ESP32, because I had a devkit lying around, and the OLED and RTC libraries were solid, and I could use WiFi to get accurate time, which is absolutely need to generate the codes, here's a picture of the first prototype.It worked fine, I used to generate a secret key from here, and then flash the esp32 with the new key and boom, it generated codes I wanted to (It was not as easy as it sounds, I had to spend days putting together a firmware to do it, and it was start of Covid-19 Lock down so I had a lot of free time).Second PrototypeI wanted to take this to next level, make something like those RSA key id devices, but more configurable and not exactly use and throw like those and ESP32 was the right tool for it. So, I designed a PCB for the same. It was a long process, I had to handle my summer internship, finally by October I finished designing it and after getting it reviewed and rerouting again after two weeks, my PCB was ready to be ordered.Final DesignAfter the second prototype I wanted to make it more sleek as the OLED was being used as a external module and it increased the height too much. So, I designed a new board, basically updated the board design by rerouting and optimizing it. You can see both designs and see the improvements.http://freecodecamp.org

The camera feed and important electrical and sensor parameters are monitored and transmitted to the base wirelessly in real-time at radio frequency.

The Team The TU Graz Racing Team is a team ofstudent from various studies. Our goal is to build one of the best FormulaStudent Racing cars every year. For the upcoming season, we decided to leaveour successful era with combustion cars behind us and to accept the challengeto build an electric race car. With our beloved TANKIA we want to get back ontop at the FSAE competitions and therefore we are giving our best in designingand manufacturing that we can. Our PCB In out team there are two moduleshandeling all the electronics. The Low Voltage Electronics module handles allthe electronics below 60V and is also responsible for the wiring harness. TheHigh Voltage Electronics module is responsible for the high voltage componentssuch as the accumulator and the motor control. Our PCBs are designed to readout all the sensors we have on the car and handle the control of all theactuators and the drivetrain. For a race car it is therefore very important tohave reliably working PCBs because of the strong dependency of data among them. All of our PCBs are equipped with microcontrollers. The software for the PCBs is also written by ourselves. Display PCB The display PCB is responsible for thecommunication between the driver in the car. It sends the commands the driveris providing through buttons on the steering wheel to other control units inorder to change driving dynamics. The PCB also drives a display which shows themost relevant data to the driver. Low Voltage Power Distribution The LVPD is responsible for providingall electrical components with power. It distributes the Power coming from theLow Voltage Accumulator to all other PCBs and electrical components in the car. Body Control Module The BCM reads out all the sensors fromthe front of the car and provides the according values to the CAN bus, suchthat also other control units can access the data. The BCM also controls someactuators such as the DRS and the Electronic Brake Balance Control. CAN Node The Can node is a PCB that evaluatessensor data from the back of the car and provides it to the CAN Bus. It alsocontrols cooling elements such as pumps and fans. Brake System Plausability Device This is one of our most important safetyfeatures. It detects malfunctioning of the braking system and stops the carimmedeatly in case of failure Motor Control Unit The motor control unit controls themotors of our care. It evaluates data from various sensors and computes acomplex control loop in order to obtain maximum performance.

We are an interdisciplinary team composed of engineers, biologists, and clinicians in the Philippines developing ways to simplify the COVID-19 testing process. We have four ongoing state-funded research projects housed in the Ateneo De Manila University. One of the projects we are working on is the validation of a rapid, simple and efficient Isothermal COVID-19 testing technology.To achieve this, we will be reproducing Miriam, the open-source isothermal amplification platform by Miroculus. This device can run Loop Mediated Isothermal Amplification (LAMP) reactions to amplify DNA on a standard 96-well plate and it comes with real time detection of the reactions via optics. It performs this task by heating up the plate to a desired temperature and maintaining that temperature to enable amplification reaction conditions. For the optics, there are 96 LEDs and 96 photodiodes separated by an emission filter. As this is open source, all documentation can be found on GitHub.This Arduino Mega-controlled instrument is composed of 4 PCBs: two heating boards, an LED board for detection optics, and the Arduino shield. The heating boards are based on the principle of Joule heating and will be using the heat generated by the current flowing through the copper traces. In the middle of the board is a 10 kohm SMD thermistor.Figure 1: Heater BoardsThe LED board is used for fluorescence detection using 96 LEDs and 96 photodiodes for the 96-well plate.Figure 2: LED (left) and photodiode (right) PCBsLastly, the Arduino shield “contains three MOSFETs to control LED board and the two heater boards, the required components to read the heat from the thermistors as well as a WIFI chip. The WIFI chip makes it possible for Arduino to be connected to a local WIFI and this way communicate autonomously to a web service.”Figure 3: The Arduino ShieldWe are interested in having PCBWay to produce and assemble the 4 PCBs required for this open-source platform. PCBWay has been our chosen fabricator even for our previous PCBs because their manufacturing tolerances are fit for our current and future needs. With very accommodating sales representatives, working with this company has always been a great experience.
