Projects on this page (Developed for Nestwell Technologies):

1) A registration system for events to print out QR code badges for Events

2) RFID Welcome screen for events using Flask and MySQL

3) Home automation controlling electrical loads in the home from anywhere around the world.

4) An RFID based attendance system prototype operating on GSM

Quick and easy Registration system

Developed along with Selena Vaz, Deepika Parashram and Ashish Aware at Nestwell Technologies.

An Android app running on tablet allowed people to print badges of their names by preselecting there names from a list (Fed by the organizers into a Cloud database) or print a new badge with a new name by entering all relevant fields. The system then assigned a unique number to the person, part of which was embedded into a QR Code. The data simultaneously synced to the cloud was sent to a Linux machine which ran a program that generated the QR code and badge using imaging libraries and printing the image from a Label Printer. The QR code could then be used at the Welcome screen to get an attendee count( as this would capture the attendees who had been pre sent the badges) and could also be used at other attractions such as the slingshot and photo booth at the event.

Below is a video of the implementation of the system at the TATA Weconnect event hosted across India in Mumbai, Delhi, Bangalore, Hyderabad, Chennai and Kolkata. The system reliably printed and over 6000+ badges for the events and captured their attendances.

RFID Welcome Screen:

Description: A screen connected to a Linux laptop runs in kiosk mode by launching chromium from a bash script on startup. The propped up webpage opens a websocket connection with a Flask program . Inside the Flask program is running a keyboard reader using a Python module. This module reads the RFID USB reader and the data is then cross-referenced with a database using MySQL and the name is sent to the screen via websocket while the attendee count is updated. For its actual use in the events, the rfid reader was replaced by a USB based HID QR code scanner.

The following pic is a shrunken prototype attempting to do the same with a Raspberry PI and a 5 inch screen for events.
