This is a simple power source that can be turned On or Off via a transistor using the I/O pins of any microcontroller. It can also be turned permanently on by soldering the T and 3V3 pins together. Connect battery + (15V max.) to the BAT+ pin. Connect battery - to the GND pin. 3.3V (500mA max.) will be available on the 3V3 pin.5V (1A max.) will be available on the 5V pin.The T pin is used to turn On/Off the power source. It can be connected to an Arduino I/O pin. When the pin will be HIGH, the power source will be On. When the pin will be LOW, the power source will be Off. Or the pin can be connected to the 3V3 pin to keep the power source permanently ON. Here is the schematic for the power source.And this is how it looks like when soldered on.Here is the BOM file.

TvG Kart Data Logger v4.0Here is a video showing some of the functionality of my project.https://www.youtube.com/watch?v=DxGiBHLMiP4I am Pintea Mihăiță from Romania. I am a hobbyist in electronics. As you can probably figure out, I like karting. In fact I have a 125ccm KZ2 Shifter kart. With my project I aim to build a cheap data logger for Karts. (2 stroke, 4 stroke, single speed or 6 speed karts)The professional solutions found today on the market are very expensive for those who consider karting just a hobby.My project uses the minimalist design of the Teensy 4.0 to log a lot of data in real time and transmit it via Bluetooth to a phone running the RachChrono app (that can be mounted on the steering wheel of the kart for live info or could be placed in the pocket for data logging only) and via a NRF24L01+ module to a hand held device that can be used by spectators (team or friends up to more than 500m away) to read the data. Also, the data is shown on a 2.42” oled display that can be mounted on the steering wheel and which has shift lights.Data logged/transmitted:· Acceleration pedal position· Brake pedal position· Steering wheel position· RPM (from an induction sensor mounted on the lead to the spark plug)· Wheel speed (either front wheel or rear wheel)· Current gear (for shifter karts)· G-forces· Lap time (using the magnetic strips in the track)· Heart rate (BPM)· GPS position The Teensy 4.0 microcontroler logs all this data and transmits it to a Bluetooth device running the RaceChrono app for Android. It sends the data so the app displays all of it in a user friendly interface and can be later used for analysis. Together with the GPS functionality of the RaceChrono app, the system is very robust. It also has the functionality of a ‘walkie talkie’.All the soldering was done manually by me (except for the prefabricated modules) and all the PCBs were ordered on PCBWay.com.

This is a breakout board for the new TvG KDL (DIY Kart Data Logger) using the powerful Teensy 4.0. It has incorporated the following modules:· HC-05 Bluetooth· Teensy Audio Adapter (adapted to the new Teensy 4.0)· A TRRS 3.5mm audio jack· NRF24L01+· MPU 6050· Battery mounting (4xAA or 1x9V)· 2.25 pin header for the Teensy 4.0 pins· Pull-up resistors for the I2C bus This board can be used to test the new Teensy 4.0 board functionality. It will also be used for my TvG KDL project. This is a Kart Data Logging system. It records data from a 125ccm Kart and logs it to the RaceChrono app on a mobile phone. The data is also displayer on a Oled display mounted on the steering wheel. Given the Teensy 4.0 board functionality, now I can use my TvG KDL like a Walkie-Talkie also to be able to comunicate with the pit crew. Data logged/transmitted: · Acceleration pedal position· Brake pedal position· Steering wheel position· RPM (from an induction sensor mounted on the lead to the sparkplug)· Wheel speed (either front wheel or rear wheel)· Current gear (for shifter karts)· G-forces· Lap time (using the magnetic strips in the track) · Heart rate (BPM) Basically, I am now building the 4.0 version of my TvG KDL. In the following picture you can see the 3.0 version.The 4.0 version using the board I am trying to get sponsored will use a Teensy 4.0 instead of the STM32 microcontroller and will have the added functionality of a Walkie-Talkie. This involved major design changes. Thank you for considering my project and thank you for considering sponsoring me. This way I can build my project as a hobbyist. Thank you PCB Way!

This is a 2.42 inch Oled display that can be mounted on a Kart steering wheel. Then, using the 2 RJ45 ports, it can be connected to a TvG KDL Data Logger to display all the information gathered from the different sensors on the Kart:· Acceleration pedal position· Brake pedal position· Steering wheel position· RPM (from an induction sensor mounted on the lead to the sparkplug)· Wheel speed (either front wheel or rear wheel)· Current gear (for shifter karts)· G-forces· Lap time (using the magnetic strips in the track)· Heart rate (BPM)It is also used to setup the Data Logger. (Calibrate the position of the acceleration and brake pedals, and choose how many sectors the track is divided in - for the lap time)The shift lights on the top light up just like those on the steering of F1 cars and show when to change the gear optimally (for shifter karts). Or can be use to determine rpm for other karts. Using the two buttons, the user can navigate through the menu choosing the data he wants to display.Thank you PCBWay for sponsoring me for other projects too. I could not sustain my hobby without you because I live in Romania and the shipping is expensive here. With the sponsorship program I hope to raise enough for a 20x20cm PCB to include all the PCBs needed for my TvG KDL project. Thank you very much.

TvG Kart Data Logger v3.1This is a big improvement over the last iteration of the TvG Kart Data Logger.With my project I aim to build a cheap data logger for Karts. (2 stroke, 4 stroke, single speed or 6 speed karts)The professional solutions found today on the market are very expensive for those who consider karting just a hobby. Only the main unit starts form around 300 USD. Then you would have to buy all the sensors.My project uses the minimalistic and powerful design of two LGT8F328P (basicly a 32 Mhz Arduino Nano) to log a lot of data in real time and transmit it via Bluetooth to a phone running the RachChrono app (that can be mounted on the steering wheel of the kart for live info or could be placed in the pocket for data logging only) and via a NRF24L01+ module to a hand held device that can be used by spectators (team or friends up to more than 500m away) to read the data. Also, the data is shown on a 2.42” oled display that can be mounted on the steering wheel and which has shift lights.Data logged/transmitted:· Acceleration pedal position· Brake pedal position· Steering wheel position· RPM (from an induction sensor mounted on the lead to the sparkplug)· Wheel speed (either front wheel or rear wheel)· Current gear (for shifter karts)· G-forces· Lap time (using the magnetic strips in the track)· Heart rate (BPM) The two LGT8F328P micro controllers log all this data and transmits it to a Bluetooth device running the RaceChrono app for Android. It sends the data so the app displays all of it in a user friendly interface and can be later used for analysis. Together with the GPS functionality of the RaceChrono app, the system is very robust.The upgrade to the LGT8F328P chip is useful because of the 32 Mhz speed of the chip and the 1 real DAC converter the chip has. This makes it easier to implement the Walkie Talkie functionality.

Hi. I am Mihai from Romania.This is a simplified version of a induction RPM sensor. This is designed to be used along with an Arduino of any sort. You have to use a solid copper wire and twist it 9 times around the lead to the spark plug then connect it to the COIL+ terminal on the board. The circuit uses the inducted current to switch on and off a transistor which in turn sends a signal to the Arduino used to calculate RPM. Thank you PCBWay for making this possible. Thanks to the sponsorship program I can build my PCBs easily and I can promote your services. PCBWay manufacturing cost is very low for the average consumer. THANK YOU!

This is an addition to the TvG Kart Data logging System that I designed. It is a wireless hand held board that displays all the data sent over wireless serial buy the TvG Kart Data Logging System and it can be used by the people watching from the sides. It is always good to impress the viewers with your top speed or with the fact that you did not lift through a corner. :) The hand held device has a very long range (approx. 1km). You can extend the range by adding an antenna to the hand held device using the IPEX connector. I also tested the wireless communication inside a concrete building and it works very well through the walls.The wireless system displays the following: · Lap Time in seconds.· Wheel speed in km/h· Engine RPM· Current gear· Acceleration pedal position· Brake pedal positionYou can view this data one at a time or all in one screen with nice graphs for acceleration and brake pedal position. Other than displaying data, the hand held device helps with setting up the sensors on the TvG KDL. Because the system is designed to be mounted on any kart, the acceleration and brake pedal sensors need to be calibrated once for every new installation. (Or when you see that the data is off by a margin on the display.) To enter setup, just flip the switch on the main board do SETUP and follow the onscreen instructions. This way the system will know when the pedals and released or at 100% regardless of where you mount the sensors. This is all made possible by PCBWay and their very cheap but very professional PCB manufacturing process. The display can be powered either from a power bank, or from a rechargeable LiPo battery mounted inside.Thank you very much for the opportunity to apply for sponsorship and I would be very happy if I would get sponsored because even though the manufacturing process is very cheap, the shipping to Romania costs about 30 USD. This for a hobbyist is not that little.

TvG Kart Data Logger (on the cheap) My project aims to build a relatively cheap data logger for Karts. And I am talking about all sorts of Karts – 2 stroke, 4 stroke, professional, amateur, single speed or 6 speed. The professional solutions found today on the market are very expensive for those who consider karting just a hobby. Only the main unit starts form around 300 USD. Then you would have to buy all the sensors. My project uses the minimalistic design of the Arduino Nano and Arduino Pro Mini to log a lot of data in real time and transmit it via Bluetooth to a phone running RachChrono (that can be mounted on the steering wheel of the kart for live info) and via wireless serial communication to a hand held device that can be used by spectators (team or friends). But more on this device later. The TvG Kart Data Logger (TvG KDL) in its current configuration can log acceleration and brake pedal position, RPM (either from an induction sensor mounted on the lead to the sparkplug or from a hall sensor mounted near the magnets on the crankshaft used for ignition), wheel speed (either front wheel or real wheel), current gear (for shifter karts), and later I plan to add two temperature sensors (one for engine and one for ambient), an accelerometer (for measuring G-forces), and a lap time magnetic sensor. The Arduino logs all this data and transmits it 10 times a second to a Bluetooth device running the RaceChrono app for Android (the developer of the app says that in the future the iOS devices will be able to use the Bluetooth connection as well). It sends the data so the app displays all of it in a user friendly interface. Together with the GPS functionality of the RaceChrono app, the system is very robust. The TvG KDL also sends all the information to a wireless hand held device that can be used by the people watching from the sides. Other than displaying data, the hand held device has no other functionality. But it is always good to impress the viewers with your top speed or with the fact that you did not lift through a corner. J The hand held device has a very long range (approx. 1km). You can extend the range by adding an antenna to the hand held device using the IPEX connector. I also tested the wireless communication inside a concrete building and it works very well through the walls. Thank you very much for the opportunity to get sponsored. It really helps us, amateurs, to be able to build these projects. Also the quality of the PCBs produced here is awesome.

DESCRIPTIONThis is a project that I am working on because I am a karting enthusiast. There are many great commercial products that log data on a Kart. But they are very expensive, always costing hundreds of EUROS. This is a low cost data logging project. It will log acceleration position, brake position, G-forces, RPM, speed, engine/outside temperature, lap time, and gears. With the possibility to add more sensors, depending on your needs.Not only this, but it will transmit this data to a free app for Android and iOS (RaceChrono) which can log also GPS position and show the data in graphs, while displaying all this on a mobile phone.With the wireless device (which has its own battery so you can put it in your pocket if you want), you can have a coach monitor all this data while sitting on the side of the track so that he can give you precious information to help you in your practice. Or just have you friends watch the G-forces while you zoom by at 130kph. TECHNICAL DETAILSThe project comes with all the sensors attached. You only have to mount the sensors on you Kart, connect them to the main board, connect the power source (a 5V battery) and go racing. Thank you very much for considering my project. When it is finished (PCB made, parts installed and mounted on the kart) it will be used in enthusiast and national karting events. We are a few friends who like karting and want to use this. If we will get your sponsorship, all the PCBs will be made on PCBWay. If you want, along with the PCBs, you can send us some stickers with PCBWay so that we can put them on our karts and promote the site. After the PCB manufacturing and installing the project on the kart, we will make a few videos showing the project, how it works, and promoting the site if you want. We will also post pictures showing the project on a few karting forums, both national and international.The total cost of the project is approximately 80USD+PCB manufacturing and shipping. We would be very happy if you can sponsor us. Thank you very much.

### DESCRIPTIONLog data from your Kart to a Bluetooth device using a few sensors. In the current configuration the system transmits RPM, gear, lap time, accelerator and brake pedals position and temperature.Change the refresh rate of the device and other settings using serial Bluetooth communication. ### TECHNICAL DETAILS / COMPONENTSYou will need: An Arduino Nano (or another Arduino board), 4 Hall effect switches, 3 Linear hall sensors, one Bluetooth HC-05 module, 5 resistors 2.2k Ohm, and 1 resistor 1k Ohm.As it is now, the Bluetooth module sends data to a RaceChrono app on your mobile device.You can modify the code to send data to another application. ### Words to PCBWayThank you for givving me the opportunity to apply for sponsorship. I would not have the resources to build this. You offer an awesome service with the PCB fabrication.Thank you and have fun.

A CanSat is a simulation of a real satellite, integrated within the volume and shape of a soft drink can. The challenge for the students is to fit all the major subsystems found in a satellite, such as power, sensors and a communication system, into this minimal volume.The CanSat is then launched by a rocket to an altitude of about one kilometer, or dropped from a platform or captive balloon. Then its mission begins. This involves carrying out a scientific experiment, achieving a safe landing, and analyzing the data collected.CanSats offer a unique opportunity for students to have a first practical experience of a real space project. They are responsible for all aspects: those sensors and sending it to the base station, situated on the ground.My team must build a CanSat and program it to accomplish a primary compulsory mission and a secondary one.The primary mission consists of measuring the following parameters and transmitting the following data as telemetry to the ground station at least one every second: · Air temperature – BME280 temperature and pressure sensor· Air pressure – BME280 temperature and pressure sensor The secondary mission of the CanSat must be selected by the team. We decided on the following: · Targeted landing using a parafoil – using Servo Motors for steering· Measure photosynthetic activity with a special camera filter – PTC06 Serial Camera + Infragram Filter· Gather GPS data (also helpful for targeted landing) – FONA 808 All the data will be transmitted using a LoRa (Long Range) RFM95W Transceiver.
