Description:

Tonight, we venture into the hidden depths of the #media's most clandestine practices - #sonic #manipulation and #mindcontrol. We're joined by #Veritas veterans, John and Bonnie Mitchell, who have dedicated their lives to uncovering these veiled technologies.

The journey begins with John's unsettling discovery of secret sonic weapons embedded in a popular movie. This revelation opens the door to a world where #infrasound and #ultrasound are not mere scientific phenomena, but tools for covert influence and harm. We'll delve into the intricacies of a mysterious wave file, an apparent breadcrumb in the larger scheme of media manipulation.

Bonnie, with her wealth of experience, sheds light on the alarming health effects associated with these hidden frequencies. Drawing parallels to the notorious Havana Syndrome, she reveals how deep the roots of these technologies run, entwined within the fabric of our daily media consumption.

Bio

After retiring from distinguished careers in the United States Merchant Marines, John Mitchell and his devoted partner, Bonnie Jean Mitchell, embarked on a mission that would reshape their lives and illuminate hidden truths. Together, they founded Awakenvideo.org, a platform dedicated to unveiling the secrets and disinformation perpetuated by the clandestine forces within the government. Their journey led them to delve into the intricate world of mind control techniques imposed upon the unsuspecting masses. In 2012, John and Bonnie unveiled the unsettling reality of Digital Mnemonic Mind Control through their research.

Bonnie Jean Mitchell, a luminary in her own right, stands as the visionary founder of Alienabductionhelp.com. She is a multifaceted researcher, accomplished author, and a lifelong contactee with extraterrestrial entities. For over two decades, Bonnie has provided guidance and solace to individuals navigating the enigmatic realms of paranormal and metaphysical experiences. Her literary contributions include the insightful books "Journey with the Star People" and "The Shift: A lifetime of Contact Leading to Higher Consciousness."

In 2014, John and Bonnie made the daring choice to leave the United States, setting their course for Uruguay in South America. Today, their focus remains steadfastly fixed on the spiritual battle being waged as humanity seeks a transformative paradigm shift in consciousness. You are invited to join their thought-provoking Awakenvideo Livestream, hosted on Rumble, every Friday night at 6pm EST, where they continue to shed light on vital issues shaping our world.

For millennia, musicians have looked to the #heavens for #inspiration. #Now a new collaboration is enabling actual data from NASA telescopes to be used as the basis for #original #music that can be played by humans.
enter image description here
Since 2020, the "sonification" project at NASA's Chandra X-ray Center has translated the digital data taken by telescopes into notes and sounds. This process allows the listener to experience the data through the sense of hearing instead of seeing it as images, a more common way to present astronomical data.

A new phase of the sonification project takes the data into different territory. Working with composer Sophie Kastner, the team has developed versions of the data that can be played by musicians.

"It's like a writing a fictional story that is largely based on real facts," said Kastner. "We are taking the data from space that has been translated into sound and putting a new and human twist on it."

This pilot program focuses on data from a small region at the center of our Milky Way galaxy where a supermassive black hole resides. NASA's Chandra X-ray Observatory, Hubble Space Telescope, and retired Spitzer Space Telescope have all studied this area, which spans about 400 light-years across.

NASA's Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory's Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

"Where Parallel Lines Converge" is a #sonic rendering of a composite image of the #GalacticCenter, or the center of our #MilkyWay #galaxy, with data from NASA’s #Chandra, #Hubble and #Spitzer #space #telescopes. The song is a tryptic, highlighting three astronomical objects or moments in the image: the X-ray binary, the arched filaments, and the #supermassive #blackhole, #SagittariusA*.

The piece was conceived using the same principles as the original NASA Chandra data sonifications, converting data to sound by matching different parameters of the image with musical parameters. Composed by Sophie Kastner, this was recorded by #Montreal based #Ensemble Eclat conducted by Charles-Eric LaFontaine on July 19, 2023 at McGill University.

  • one can install a very decent Debian and have okay working speed so yes it can be seen as a very energy efficient (5V based) and still usable (definately faster than pi2) desktop system (99% of all packages available
  • clock for performance: one can manually set the CPU to “performance” with the tool: <span style="color: #00ffff;">gksu odroid-cpu-control</span>

or

  <span style="color: #00ffff;">/usr/local/sbin/odroid-cpu-control</span>

(maximum clock speed at all times) but then things get very fast but also 90°C and more hot (very very hot) so not recommended, so better to select “ondemand” and “from 200 Mhz to 1400 or 2000 Mhz
- if one needs maximum performance consider installing active cooling fan and set clock to permanent maximum.

Super Mario Kart (retroarch) can be played pretty smooth (50-60fps at about 60-75°C) with a little cpu tuning.

this blog post update is written on the xu4 Debian Jessie 8 (Game Station Turbo Image, (direct download link) then recommended to download 500MBytes of updates then firefox stable) and Firefox 60.9.0esr (32-bit)

one is pretty new to Kodi (it comes with older version Javis) can’t really say anything about it… have never used it.

what it does not:

  • it does not 1080p full hd with 100 frames
    • it is okay at 720p but still one is wondering: where is the GPU hardware acceleration? the 8x ARM CPUs seem to do all the work on Firefox playing Youtube on Debian 8 (hd is stuttering)
    • kodi (latest version on android) plays stuff fine
  • netflix.com refused to work (well this guy has managed to even on an older C1)

tried all possible variants (if one got it working let me know)

suspected problem: no Widevine Support? (Google Chrome will drop 32-bit machines but Chromium is still going. (Source))

so this could be the problem… that 32Bit ARM is simply not supported by Widevine?

(Raspberry Pi 3 can run it… the older Raspberries seem too slow for the job)

neither Debian 8 (Jessie) Firefox (60.9 esr) nor Android + NetFlix App (won’t install straight from Play Store because it says “hardware not supported” but even when one exports the App via AppExtractor from a Android Phone and installs it on Android on xu4 Netflix refuses to work 🙁

who needs netflix if one can have Scott Manley’s Youtube Channel about Space stuff? HURRAY 🙂 (one is serious about this… really love it)

what does it look like?

What SoC are you using?

The SoC is a Samsung Exynos5422 Octa.

What GPU does it include?

An ARM Mali-T628 6 Core.

heat

Complex components such as the XU4 processor may reach temperatures as high as 95°C. At high temperatures, the processor will throttle itself and operate slower so that temperatures do not continue to increase.

robotics

The 30-pin GPIO port can be used as GPIO/IRQ/SPI/ADC, and the 12-pin GPIO port can be used as GPIO/I2S/I2C for electronics and robotics. The GPIO pins on an ODROID-XU4 are a great way to interface with physical devices like buttons and LEDs using a lightweight Linux controller. If you’re a C/C++ or Python developer, there’s a useful library called WiringPi that handles interfacing with the pins, which is described in Chapter 4. Note that all of the GPIO ports are 1.8Volt, and the ADC inputs are limited to 1.8Volt. If a sensor or peripheral

needs higher voltage, the GPIO ports may be level-shifted to 3.3V or 5V using the XU4 Level Shifter Shield.

Serial console port

Connecting to a PC gives access to the Linux console. You can monitor the boot process, or to log in to the XU4 to perform root maintenance.

Note that this serial UART uses a 1.8 volt interface, and it is recommended to use the USB-UART module kit available from Hardkernel.

A Molex 5268-04a (2.5mm pitch) is mounted on the PCB, and its mate is Molex 50-37-5043 Wire-to-Board Crimp Housing.

RTC (Real Time Clock) backup battery connector

If you want to add a RTC functions for logging or keeping time when offline, just connect a Lithium coin backup battery (CR2032 or equivalent). All of the RTC circuits are included on the ODROID-XU4 by default. It connects with a Molex 53398-0271 1.25mm pitch Header, Surface Mount, Vertical type (Mate with Molex 51021-0200).

Gigabit Ethernet

The Realtek RTL8211F is a highly intergrated 10/100/1000M Ethernet transceiver that complies with 10Base-T, 100Base-TX, and 1000Base-T IEEE 802.3 standards.

USB MTT hub controller

The Genesys GL3521 is a 2-port, low-power, and configurable

USB 3.0 SuperSpeed hub controller.

setup

depending on if you can connect a monitor or not:

  1. insert micro sdcard…
  2. LAN connect ODROID XU4 to a DHCP-server ((DSL) router/fritzbox with DHCP enabled)
  3. LAN connect PC/Laptop to the same DHCP-server
  4. start wireshark on your laptop and power on ODROID XU4.

networking: dhcp and finding odroid’s ip

can be a little pain in the a….fternoon.

the ubuntu ODROID XU4 image does not come with a fixed IP, so you will have to connect it to some sort of DHCP-server (router) in order to ssh into it, or install the dhcp-server-service under debian 8. (maybe as VirtualBox VM).

you can also use wireshark and to listen to network activity related to the odroid (dhcp-offer) and find it’s IP this way.

you are looking for simething like:

15 2.286036000 <span style="color: #ff0000;">Wibrain_</span>30:cf:9b Broadcast ARP 60 Who has 192.168.0.1? Tell <span style="color: #ff0000;">192.168.1.101</span>

or use nmap network scanner to find it’s ip…

nmap -n -v -p 1-255 -n -sS 192.168.<span style="color: #ff0000;">10</span>.0/24
Initiating SYN Stealth Scan at 22:21
Scanning <span style="color: #ff0000;">192.168.10.10</span> [255 ports]
Discovered open port 22/tcp on 192.168.10.1

modify the above line depending in what kind of subnet your router is operating. (192.168.XXX.XXX)

ssh into it

usr: root / usr: odroid
pwd: odroid

            Kernel: Linux 4.14.5-92
      Architecture: arm

CONGRATULATIONS! YOU LOGGED IN SUCCESSFULLY THE FIRST TIME TO YOUR EMBEDDED POWERHOUSE!

fix the ip

to not have to hassle with dhcp servers again one can change the ip to fixed via:

<span style="color: #00ffff;">nano /etc/network/interfaces</span>

fill it with this content:

# The loopback network interface  
auto lo  
iface lo inet loopback  

# The primary network interface  
auto eth0 
iface eth0 inet static  
address 192.168.<span style="color: #ff6600;">0.111</span>
netmask 255.255.255.0
gateway 192.168.<span style="color: #ff6600;">0.1</span>
dns-nameservers 192.168.<span style="color: #ff6600;">0.1 
</span>

modify the orange parts so it fits your LAN settings – then type:

<span style="color: #00ffff;">reboot
</span>

if everything went straight… you should be able to ping the odroid on 0.111 and ssh into it on 0.111

messing with the odroid

the first thing you probably do with a new system is check for updates…

if your network settings are correct your odroid should be able to access the internet.

============ CPU BENCHMARK
sysbench 0.4.12: multi-threaded system evaluation benchmark

Running the test with following options:
Number of threads: 8

Doing CPU performance benchmark

Threads started!
Done.

Maximum prime number checked in CPU test: 20000

Test execution summary:
total time: 37.4554s
total number of events: 10000
total time taken by event execution: 299.4689
per-request statistics:
min: 23.26ms
avg: 29.95ms
max: 44.59ms
approx. 95 percentile: 40.59ms

Threads fairness:
events (avg/stddev): 1250.0000/327.26
execution time (avg/stddev): 37.4336/0.01

so the benchmark ran in 37 seconds. (rerun with the debian jessie 8 turbo game station image and performance governer: execution time (avg/stddev): 56.9216/0.01…)

on an QuadCore Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz the benchmark run in 14.60 seconds.

so the 8x core ODROID X4U is 2.5 times slower than the 4x core i5 at 1.60 GHZ using all available cores.

while doing this

<span style="color: #00ffff;">vim /scripts/cpu_temp.sh</span>
#!/bin/bash

while true ; do

cpu_temp=$(< /sys/class/thermal/thermal_zone0/temp)
cpu_temp=$(($cpu_temp/1000))
echo $cpu_temp C

sleep 1;
clear;

done # executes COMMAND every second

i monitored the temp of the cpu for around 30minutes while running all 8 cores full speed.

the system is PASSIVELY cooled and seems to throttles the CPUs automatically when 80 degrees Celsius are reached.

maximum measured temp was 82 Celsius (179.6 F).

the passively cooled case got warm but not uncomfortably hot. i have heard raspberry had problems with heat.

when the benchmark was over the temps dropped instantly to 53 C.

Real Time Clock: RTC

just as the Raspberry pi, the odroid needs a battery to keep clock when it is turned off.

ODROID-HC1 no HDMI but SATA version

there is/was a NAS/SATA variation (headless, no GPU, no HDMI, no screen/monitor) : https://www.pollin.de/p/odroid-hc1-einplatinen-computer-fuer-nas-und-cluster-anwendungen-810766 for 60€.
