Introduction to MindSphere Analytics APIs - The notebooks use @mindconnect/mindconnect-nodejs CLI for API calls.

Data files and Matlab codes for analyzing a multilayer thin-film photonic radiative cooler

mVARbox is a Matlab toolbox for uni/multivariate data series analysis in both time/space and frequency domains, with focus on mutivariate autoregressive (VAR) models

This repository contains a model for Digital communication system employing 32-ary PSK modulation scheme for a Bird signal.

A wrapper for the Tektronix RSA API for Linux, which streamlines control of Tektronix RSA devices using Python.

Offline-first satellite RF observatory for SDR capture, deterministic DSP, orbital propagation, and evidence-based candidate scoring.

SpectraMatcher is a fast, GUI-based, interactive Python program for comparing computed and experimental vibronic spectra. It features real-time spectral adjustment, automated peak assignment, type-specific anharmonic corrections, and export to publication-ready formats. Supports Gaussian log files and plain text or spreadsheet experimental spectra.

Passive RF rogue-emitter detector — finds hidden cellular modems, rogue APs and wireless bridges in air-gapped OT sites from a spectrum sweep, transmit-free.

This repo parses and preprocesses the binary files created by the CFRS RFeye Node Logger Script

Digital Singnal Processing Practice

HTML/JS timeline of videos recorded by a Raspberry Pi camera with corresponding audio spectrogram for audio analysis

Professional audio quality analyzer for Windows that scans and grades music libraries from S to F using FFmpeg-powered spectrum analysis. Detects upsampling artifacts, clipping, stereo phase issues, and evaluates loudness via EBU R128 with full batch processing and export support for CSV, JSON, and plain text reports.

Project Ouroboros is a modular, dual-use cybersecurity platform encompassing multiple ESP32-based hardware and firmware modules for wireless defense, monitoring, and controlled research/offense experiments.
