VISION CONTROLLED ASSAULT ARMAMENT
​
A system that enables a soldier to target and fire a weapon by tracking his head movements. It comprises of two sub systems, a wearable VR like Headset (SPOCULUS) with a display,hand trigger and a Remote Targeting Module (RTM) to which the weapon is mounted. The headset houses a mechanical pitch sensor and a HMC5883L compass to track the soldier's head, this data is then processed by a microcontroller (PICAXE) into pitch and yaw coordinates and then transmitted to the RTM with an XBee transceiver. This system significantly reduces war causalities as the soldier is far away from the war zone.

VU METER (STEREO)
​
A compact unit with two precision calibrated VU meters driven by a class d audio amplifier. The meter is a vertical displacement type and the stereo channels can be switched individually. The input audio is buffered with a PAM8403 amplifier and then converted in to DC with a diode bridge before the signals reaches the meters. This unit enables the user to monitor the levels with utmost precision during audio mixing and mastering.

ELECTRONIC QUICK SHIFTER
(Mini Project)
​
A module that uses an actuator (SERVO) to shift gears of a motor bike with a press of a button instead of clutches and shift levers. The EQS is used in combination with a Ride-by-Wire system. When the shift switches are pressed the microcontroller immediately dips the throttle and actuates the gear selector shaft to shift gears. This process does not involve the rider to use the clutch, thus the gear shifts are made in a few milliseconds. This allows the motorbike to achieve greater acceleration along the power band.

A BOOKLET ON AMPHIBIANS OF WESTERN GHATS
​
An small booklet containing prominent frog species found in the Western Ghats. This project requires me to venture out to different parts of the forest system during the monsoon to sight, photograph and record calls of various frog species. I believe that this booklet will serve as a handy field guide.

Personal Hobby / Project
Project commenced in the year 2015
ACCELEROMETER CONTROLLED POWER TRAIN
​
A PICAXE based module that senses hand movements (gestures) and controls a hobby RC car. The module uses an ADXL335 accelerometer to sense pitch and roll of the palm. This data is then read&processed by a microcontroller which then determines the gesture and controls the car. The whole unit is made wearable and can be strapped to the palm. This concept can be scaled up for controlling a regular car.

MAUDIO DELTA RACK INTERFACE MODULE
​
A 2U size audio rack module which serves as an outboard distribution/patchbay to various inputs and outputs of the MAUDIO DELTA 410 24/96 sound card. The card has 2 in / 8 out analog channels and can be used with the rack interface. The rack module has an LCD displaying the status of each channel. The individual input and output channels can be switched on&off as and when needed with a dedicated channel-arm switch. The module can also be operated with a visual basic application*.

INTELLIGENT DOOR LOCK
​
A lock module that uses an electronic key to unlock the door instead of conventional metal keys. The keys are preset digitally with several possible combinations. This module is theft proof as it is tedious to unlock without an authorized key. The lock is driven by a metal gear digital servo for added protection. If the module detects a preset number of unsuccessful attempts the lock drive (servo) is temporarily disabled and can only be enabled with the master key.

PICAXE 20X2 MICROBOT
​
This is the bot which I received as a compliment for winning the project contest held by PICAXE on August 2013. I received a kit which I had to assemble. The bot uses a patented microbric system for assembly. The kit included many sensors from which I decided to use the line sensor to make a line follower robot. I also used the included bump sensor to stop the robot if it hit some obstacle. This was so special to me and had a good time with it.

Ride-by-Wire Throttle Controller
​
A controller that electronically actuates the carburetor's throttle valve according to the position of the throttle stick. The stick has a potentiometer that gives out an analog voltage value relative to its angular position. This value is then read by a microcontroller and then maps its with the servo limits. It then sends out a PWM signal which directss the servo to the desired position. Ride-by-Wire uses an electrical wire for inter-connection rather than conventional mechanical cables.

SOUVENIR DISPENSING MODULE
​
A SERVO based module which is a sub part of a nature QUIZ that dispenses a souvenir when the operator receives a score of 100. The souvenirs are boxed and stacked in a removable magazine and the whole mechanism is similar to a file stapler. When the quiz operator scores a 100, a signal is sent to the servo controller board which actuates the servo arm, pushing a souvenir box into the tray where the operator can collect his prize. The magazine is fitted with a sensor that triggers a warning light when the stack is empty.

OXYHYDROGEN GAS GENERATOR
​
An apparatus that converts water into a gas consisting of Hydrogen & Oxygen by electrolysis. This gas is then filtered to remove moisture and then passed through a flash back arrester (HHO is inflammable) before metering it into the air intake of a Spark Ignition engine. The HHO gas increases the thermal efficiency as well as reducing the Specific Fuel Consumption. This improves the mileage, thus making the operation economical and less polluting. The test which I conducted showed a 30% increase in efficiency*.

SHOP FLOOR AUTOMATED GUIDED VEHICLE
​
A Concept Robot that navigates itself around a shopfloor by tracking a line laid on the floor. It can be used for transporting parts and finished assemblies to various stations along the production line for effective production. The bot uses two pairs of infra-red line sensors which senses the line. This information is then processed by a microcontroller which controls two drive motors through a motor driver chip. Thus the bot effectively navigates around the shop floor following the line.
