Precision Wire Race - A carnival game creation

On the 25th of June 2022, BMSIT&M hosted their annual fest - Utsaha Vaibhava for which I volunteered to be part of the core planning committee and undertook the responsibility to design a carnival game. The game stall was placed in the central junction of the college campus and was played by around 400 students. The fastest to finish the game end to end won a cash prize.

The circuit used was extremely simple and consisted an Arduino board that completed a circuit of open wire drawn from a constant DC power source of 5V whose open end was looped and placed on the edge of the 'U' shaped wooden frame on the start side (left). Once the Arduino detected the completion of  circuit - when the player touches the looped wire to the main wire, a buzzer along with an led receive a 5V supply that would trigger them notifying the player that they lost the game. The circuit diagram is as shown in the figure below. The maze was made to challenging at the very end only. This prompted players to attempt the game several times as they would fail when they are at the end of the maze. This created a crowd around the game which developed its own audience of students cheering on their friends. Word about the game spread through out the campus and over the afternoon the line grew longer and longer.





Unofficially, this game was the most played game during Utsaha Vaibhava 22' . Even the college dean, Dr. Anil G N and our principal Dr Mohan Babu G N enjoyed playing the game I set up inspired by an episode of 'Mr. Bean' the live action series.

GSM Based Remote Load Switching

Abstract Today the energy meter is placed in the domestic or commercial sites and collects the data of the energy consumed and displays it on either a number dial or digital display. At the end of every billing cycle the person from the service provider has to visit the place where the meter is placed to get the reading and to note it down for further bill generation. The present system of energy charge is fallible and also long. So the purpose of this project is to develop an energy meter which is used to measure the consumer’s power consumption in kWh but also enable and support real consumption and, so meter reader does not need to visit each customer for the consumed data collection and to distributed the bill slip. The energy consumption is calculated using the measurement of voltage and current. It also continuously reads the energy meter readings and automatically sends some updates like low-balance alert, zero-balance alert, recharge alert when necessary, to the registered numb...

RISC-V ALU: Design, Implementation, and Testing

Image
 Abstract This documentation presents the design and testing of an Arithmetic Logic Unit (ALU) model for a RISC-V architecture. The ALU is capable of performing various arithmetic and logical operations while also providing flags such as Carry, Overflow, Zero, and Negative. Introduction The ALU is a fundamental component of any processor, responsible for executing arithmetic and logical operations on data. In this documentation, we focus on an ALU designed for a RISC-V architecture, which is a popular instruction set architecture used in many modern processors. The ALU model presented here is implemented in Verilog and includes support for flags to provide information about the result of operations. ALU Model  Logic Diagram  Flags and Operations The ALU supports the following operations: Operation Description Addition Adds two numbers together. Subtraction Subtracts one number from another. Bitwise AND Performs a bitwise AND operation. Bitwise OR Performs a bitwise OR ope...
