The project involved the use of a Diac-Triac pair for controlling the speed of an AC motor connected to the AC mains.

The project involved the use of a microcontroller 8051 using an IR sensor to determine the speed in RPM and Hertz of the shaft of a motor. The output of the system was displayed on a 16x2 LCD display.

Part of the Data Scientists Toolbox coursework by the John Hopkins University via Coursera.org.
Study and analysis of given hospital data using the R programming language was submitted in the form of a short dissertation.

This project designed a substitute to the traditional cane used by the blind to tackle safe spatial navigation for the blind. Ultrasonic sensors interfaced with an Arduino Uno board were mounted on a glove. When obstacles were detected below or ahead, the user was alerted using vibrator and a buzzer respectively.

Implemented an autonomous vehicle using a ROS on an ARM Cortex-A9, Phidget IMU, 2 IR Sensor. Also implemented Visual inertial SLAM, Powerslide, and Sparse map. Raced the car on a track of about 150m in 22.37s

Implemented an AWS based Embedded System to connect three RaspberryPi3 to each other and the cloud(AWS). One Rpi is mounted in a refrigerator, the second is with the User, and the third is a gateway to AWS. Python3 was used extensively to integrate and implement all the services.
The first Rpi -fridgeRpi takes a picture of the fridge periodically, splits up the image with OpenCV, and determines what items are present in the fridge using MachineLearning library TensorFlow. This data is sent… Mehr zeigen

Implemented an AWS based Embedded System to connect three RaspberryPi3 to each other and the cloud(AWS). One Rpi is mounted in a refrigerator, the second is with the User, and the third is a gateway to AWS. Python3 was used extensively to integrate and implement all the services.
The first Rpi -fridgeRpi takes a picture of the fridge periodically, splits up the image with OpenCV, and determines what items are present in the fridge using MachineLearning library TensorFlow. This data is sent to the UserRpi using CoAP. The fridgeRpi also hosts a NodeJS based server which serves HTML pages that run Javascript to keep the page up to date with current information.
The UserRpi runs a PyQT based GUI. Only authentic users are permitted to proceed as the data is protected by using a UART based RFID module. It is capable of receiving the information from the fridgeRpi using CoAP. It allows the user to place orders over AmazonDRS using the gatewayRpi. It transmits data to the gatewayRpi using AMQP protocol RabbitMQ.
The gatewayRpi makes connections to AWS services like SNS and AmazonDRS to place an order for the requested item. The user is notified over UserRpi using MQTT from a Lambda in AWS IoT. DynamoDB is used to keep track of the items ordered.
With this project, the User will be able to keep track of the food items in the refrigerator as well as place orders.
This is a project towards the completion of the course Embedded Interfaces Design Weniger anzeigen

I worked on a Voice over Internet Protocol using Real Time Systems concepts. The project utilized various real time concepts like Pthreads, Semaphores, Mutexs and scheduling. The ALSA project was used for the sound architecture and Socket Programming was implemented on both ends to transmit and receive the data. The entire system was implemented on 2 Jetson TK1 boards running Ubuntu and also tested and implemented on Laptops running Ubuntu

The outcome was a unidirectional VoIP system… Mehr zeigen

The entire system was implemented on 2 Jetson TK1 boards running Ubuntu and also tested and implemented on Laptops running Ubuntu

The outcome was a unidirectional VoIP system that could record data at 44.1kHZ 16bit stereo and transmit it over TCP to another system which would play out the sound in Real Time. The testing was performed with music and perfect transmission and reception was observed Weniger anzeigen

Developed a Cloud connected system to make a user more aware of his environment in terms of Temperature, Pressure, Humidity and Heart rate while on outdoor trips. This data stored is on a cloud server to help him make better decisions about the location of such trips for future use. The same project can also be mounted on a bike when going on mountainous trails.

Communication interfaces: BLE, WiFi, I2C, UART

In this project two games, SNAKE and RACING were designed and tested on an 8051 board. It consists primarily of 8051 board as the CPU and Graphic LCD as a display. The 8051 loads the game and runs it by utilizing internal and external memory space to display on Graphic LCD. Graphic LCD helps in improving the user interface. A gaming controller is used to control the game. An NVSRAM was interfaced for memory of the game.

Engine Knocking is a very common problem in engines which occurs when combustion of the air/fuel mixture in the cylinder does not start off correctly in response to ignition by the spark plug. This generally leads to inefficient burning of fuel which causes wastage of fuel and can damage the cylinder wall, the piston itself and the engine. In this project, we make use of an accelerometer and the temperature sensor on the FRDM KL25Z board to continuously monitor the knocking on the wall of the… Mehr zeigen

This generally leads to inefficient burning of fuel which causes wastage of fuel and can damage the cylinder wall, the piston itself and the engine. In this project, we make use of an accelerometer and the temperature sensor on the FRDM KL25Z board to continuously monitor the knocking on the wall of the combustion cylinder in the engine. If the knocking crosses a certain threshold then the user is sent an alert, the important data is logged using UART and stored on the system that monitors the data.
