10-11-2023 - Initial Release
11-11-2023 - Added Seed Modifier
12-11-2023 - Modified Seed node to accept expressions
13-11-2023 - Added Latent Noise Provider (Transforming RF Signals) using RTL_TCP

ZSuite - Prompter

This node uses files to randomize pre-defined sorted subjects of random things.

Example line:

__preable__ painting by __artist__

This prompt will be processed with random line form the file called preamble.txt in the folder:

.\comfyui\custom_nodes\Zephys\nodes\blocks\.*txt

The node uses a trigger as input from any integer value type, to enforce a new prompt output.

ZSuite - RF Node

The data capture in the RF Node is 4096 bytes / cycle governed by duration in seconds. If the data length is smaller then the Latent shape it will reset to index 0.

Then the data is processed using numpy to normalize the data in workable format shown here:

        # Ensure noise is a NumPy array
        noise = np.array(noise)

        # Obtain min/max values from noise data
        data_min = np.min(noise)
        data_max = np.max(noise)

        # Scale and inject noise into latent samples
        print(f"[ZSuite] Injecting noise...")
        for i in range(s["samples"].numel()):
            raw = float(strength * float(noise[i % noise.size]))
            data_scaled = (raw - data_min) / (data_max - data_min)
            data_scaled = 2 * data_scaled - 1
            s["samples"].view(-1)[i] = data_scaled

(Prob poorly executed, my bad!)

If you desire to change the default device parameters locate the file:

.\comfyui\custom_nodes\Zephys\nodes\ZS_Rtlsdr.py

And open with a (code/text) editor and look for this constant definition header:

RTL Device Setup

For debian:

https://manpages.debian.org/testing/rtl-sdr/rtl_tcp.1.en.html

Commandline for listening:

user@server:~$ rtl_tcp -a <ip> -p <port> -d 0

After this you setup the RF Noise node to use this ip and port.

Important:

You do need a RTL-SDR device for this node to work
