Now driving all three phases with an improved circuit design considering Rds(on), gate capacitance, bootstrap component values, and timing. I used an Analog Discovery 2 to drive the gates and analyze the phase waveforms.
A folded cascode design implementing "baby" op-amps for gain boosting, designed in Cadence Virtuoso with a teammate as the final project for Analog Electronics (ECE511) at NC State University.
As part of my work in the Vasquez Research Group at NC State University, I developed my microsoldering skills and achieved multiple working boards using 0201-size components.
Working in the research lab on tuning capacitor values to achieve optimal tuning for RF wireless charging circuitry.
The smart tourniquet near completion: the pump tightens until a pulse oximeter detects occlusion, then maintains pressure within a margin and uses PID control to reduce pressure back toward minimal occlusion pressure while keeping the limb occluded.
As part of a biomedical instrumentation class project (ECE 522), a partner and I developed and constructed a smart tourniquet system with the goal of achieving minimum blood occlusion pressure to prevent tourniquet related nerve injuries (TRNI). It was voted best class project.
In this video I am wearing a VR headset and calculating finger angle and position in Unity, then sending that data over Bluetooth to an ESP32 to control a servo.
Using an improved hall effect glove that can track multiple finger joints and a joint kinematics algorithm with matplotlib in Python to visualize the finger in 2D.
Using the hall effect sensor glove to control a servo.
The latest Synth Aesthetic version, with small software improvements and a stronger focus on aesthetics. I used white PLA to 3D print an enclosure and pushed the visualization toward 2.5D.
Using a custom sleeve to compress the electrodes on my forearm, advanced filtering, and real-time control techniques, I achieved responsive finger control using EMG signals.
