Zedboard Calculator

2022-01-27 00:24:59 UTC

The video demonstration above features a binary calculator programmed on an FPGA (Zedboard). The switches are used to input values, and the buttons are used to perform functions (addition, subtraction, multiplication, and division). LEDs display inputted values and output solutions.

I designed and tested the logic behind the binary calculator in Simulink before using JTAG to program the FPGA.

Drone Features and Functionality

2022-01-27 02:03:25 UTC

This drone is designed to be used by hikers as a modern alternative to the flare gun.

The drone uses a GPS module to pinpoint the location of the hiker within a 5 meter radius.
The Adafruit RFM95W LoRa 900Hz radio transceiver breakout module was used to burst the signal across a 2 km range.
The one-button functionality was designed to easily start the drone in emergency situations.
The flight controller help stabilize and autopilot the drone and the ultrasonic sensors help detect the obstacles vertically above it.
The strobe light was added to make the drone visible late at night and communicate distress signals to near-by rangers.

Shown above is the body casing for the drone. It is designed to insure weather proofing and durability.

The hook hooves allow the drone to be easily attached to a backpack and carried on hiking and camping trips.

This Block diagram shows the power distribution board layout and how the electrical components of the drone worked with the battery.

It also shows the one-button functionality. After the drone is activated, it will start flying within 10 seconds of boot-up time.

Line following; Solving a maze

2022-01-27 02:28:09 UTC

The RC car is retrofitted with IR sensors on the front-bottom to detect the difference between the dark and light portions of the maze.
The tape representing the line, is laid out to deliberately confuse the robot, forcing it to get stuck in a loop. In order to solve this maze, the robot has been programmed to navigate past the loops, regardless of the end of the maze it begins from.
An Arduino is used to control the three motors and program the motors to move in different torque depending on the IR sensor values. These adjustments allowed the RC car move left and right along the line.

Autonomous RC Car

2022-01-27 03:01:45 UTC

The RC car is moving autonomously parallel to the wall.
The Arduino in this scenario was taking input from the ultrasonic sensor and the motors would respectively
The biggest issue here was finding the right angles to put the ultrasonic sensors as when it will be on an angle from the wall, sometimes it would not even signify that there was a wall

Robotic Arm Programming

2022-01-28 23:09:27 UTC

The Wii remote was connected to a computer to collect data from the accelerometer.
Then the robotic arm was assembled from a kit.
The arm is programmed with C++ to mimic the motion of the Wii remote based on the data collected from the accelerometer.
The clamp is programmed to be adjustable using the buttons on the Wii remote.

Living Hinge

2022-01-28 23:18:38 UTC

Making the Rube Goldberg Machine was one of the fondest memories of my undergraduate career. We used wood 3D printers to create unique parts of the machine, which would work together to propel the small ball forward.
The live hinge was designed to be flexible and light, with enough strength to be easily held together, given the limited materials allotted for this project.

Connecting with friends

kapoor12hardik — 2023-02-07 02:52:18 UTC

MFJ QRP-Cub Transceivers use surface mount technology to achieve high performance in a pocket-sized package.
The kit includes the designed board and parts to be mounted/soldered.
The MFJ QRP-Cub was designed by QRP-ARCI (K1BQT) for real-world low-power operating conditions.
This radio was a soldering project in my frequency class but ended up being a radio for in-dorm communication with my friends.

Solenoid Controller

kapoor12hardik — 2023-02-07 03:04:01 UTC

This board design was created for KEA Technologies' patented breath alcohol testing device, which can be incorporated directly into any motor vehicle.
BITSI was constructed to control and communicate with the solenoid next to the gear of the car.
If the reading on the sensors detects the driver is intoxicated, the data coming from the DAS (Data Acquisition System) will give the information to BITSI, which will activate the solenoid to stop the gear from changing, and effectively disabling the vehicle.

Retractor Blades

kapoor12hardik — 2023-02-07 03:10:34 UTC

There are four types of retractor blades; thin, thick, thin with finger, and thick with finger. These blades will be used to hold the trachea, esophagus, and surrounding muscles during cervical surgeries.

Falcon Cervical Retractor

kapoor12hardik — 2023-02-07 03:24:02 UTC

The cervical blade retractor uses a precise system of gears to conveniently and easily make minute adjustments during cervical surgeries. The minimum movement is only 1mm retraction. The unique design will reduce the time needed for surgeries.
The retractor's radiolucent material allows surgeons to have full visibility while performing surgeries. The blade holder is sturdy and reliable. It is able to take up to 100 kg of force with each hand.

Power Distribution of DAS

kapoor12hardik — 2023-02-07 06:05:32 UTC

The power distribution boards (above) are designed to take power from a car battery (12.5V) and distribute it to the 5V Data Acquisition System.

Retractor Blade Holder

kapoor12hardik — 2023-02-07 06:17:52 UTC

These holders are used during surgeries to position the blades into the retractor.

Falcon Pad Distractor

kapoor12hardik — 2023-02-07 06:20:40 UTC

The pad distractor is used to distract space between spinal vertebrae during a slipped disc surgery. This distractor opens parallel to the cervical vertebrae, creating a precise open space.

Falcon Pin Distractor

kapoor12hardik — 2023-02-07 06:23:33 UTC

Pin Distractors are used to support pins on top of the spinal bones. The pin distractor is made of radiolucent material in order to provide greater visibility during surgeries.

A Sensor valve, usually driven by a Solenoid valve, is not a successful product in the indian market due to the mineral-rich water, making the mechanism prone to jamming. Hence, this innovation is culturally unique to places with more mineral-rich water.

kapoor12hardik — 2026-07-20 17:52:52 UTC

Making a valve that gives us limitation, a conscious decision of choosing to drain the full potential of a faucet, or halfway as required by the situation.
