gcprand is a Python library for gathering Global Consciousness Project Dot data and generating psychorandom numbers seeded by nooetic activity. It is a thoroughly unconventional entropy generator in the tradition of Cloudflare's LavaRand.

Reading through the code could provide insights into how to pull and analyze the data myself.

EntroPy: Calculate and analyze complexity of time-series data with Python https://github.com/raphaelvallat/entropy
Sun 06 Sep 2020 03:39:07 PM PDT archive.org

EntroPy is a Python 3 package providing several time-efficient algorithms for computing the complexity of one-dimensional time-series. It can be used for example to extract features from EEG signals.

EntroPy cannot be installed using pip or conda. There is already a package called entropy on the pip repository, which should not be mistaken with the current package.

Uses the mathematical analysis modules that you'd expect.

Can calculate permutation, spectral, singular value decomposition, appromate, sample, and Lempel-Ziv entropy. Can calculate Petrosian, Katz, Higuchi, and detrended fluctuation fractal dimensionality.

A method for distributing cryptographic entropy in the form of numerical values to systems that need it. Collects entropy from other systems and hashes it into the pool. While I can't vouch for how much entropy is in those values it seems interesting to experiment with.

Entropy and Random Number Generators @ Calomel.org - Open Source Research and Reference https://calomel.org/entropy_random_number_generators.html
Tue 20 Mar 2018 12:55:42 AM PDT archive.org

An in-depth description of how pseudorandom number generators work (specifically, in Linux and OpenBSD) and how to improve the entropy pools of systems. Includes instructions on testing the entropy available, running an entropy gathering daemon to keep the entropy pool full, and how to rig up a wireless network interface to seed the kernel entropy pool.

The primary instance of the NIST Randomness Beacon. Has a REST API for access (which is going to change). Pull random numbers out of it but don't trust them because you didn't generate them yourself.
