Half Gallon Brain in a Jar

Built by Humanoido in June of 2011, this award winning pint sized "brain in a jar" was a first at HL, having the ability to think, ask questions, and carry on a rudimentary conversation. With 128K RAM/ROM, the AI life form could evolve to a higher state of knowledge after the initial power-on and talking to humans. It utilized sixteen cores based on two Model 1 Parallax Propeller chips. The "serial number one" Pint Size Brain PSB still exists, displayed in the HL Museum gallery.

HALF GALLON SIZE
BRAIN IN A JAR
TWO years ago when a pint sized brain in a jar was built, it contained two Parallax Propeller chips for a total of 16 cores, could think and learn, and was completely housed in a recycled peanut butter jar.

HALF GALLON SIZE BRAIN HGB
Today, a new project in the works has improved vastly over the pint sized brain and the subsequent project, the Jar'd Brain (see below). The half gallon sized brain has more multiprocessors, more features and can do more brain thinking. The light weight larger polymer peanut butter jar allows many more Propeller chips to fit inside, along with a power supply, solar panel, and additional sensors and peripherals.

LEFT: The pint size Brain in a Jar was a two chip quick build, with one chip mounted on top of the other.

PEANUT BUTTER JAR
A polymer peanut butter jar is used as a housing, simply because it's free, it's the perfect size, it's durable and won't shatter like glass, it can recharge batteries through its transparent sides, and it recycles to help save the Earth. Scoop out the peanut butter and throw it away to maintain a lean diet. The jar could also self-contain sealed mineral oil to act as a cycling coolant for running the brain at overclocked speeds. A clear jar allows viewing of LED status lights, and it can show the output of a serial LCD through the jar. Light sensors also work for detecting light levels outside of the jar.

AUTONOMIC
It's an automatic brain, i.e. you only need to talk to it, if you want. It self charges. It's spontaneous and it will volunteer conversation and information.

PURPOSE
Same as its predecessor, the primary purposes of the Half Gallon Size Brain in a Jar are thinking, learning, evolving, and experimenting, but at a higher level.

THINKING
The HGB is faster thinking with more cores and chips. Chips and cores function in parallel, and Brain Lobes are introduced to increase learning, retention and recall.

BRAIN LOBES
Multiple instances of learning channels, or brain lobes, are at the implementation of one brain lobe per chip. Each Brain Lobe can learn new and different information compared to the others. Brain Lobes function in parallel. All brain lobes are preloaded with the same basic information and allowed to evolve to a higher state.

DESIGN
Propeller chips are no longer piggybacked, for a more safety efficient design. The multi chip design allows thinking in Parallel.

LEARNING
It uses the new upgraded Learner program by Dave Hein and saves memory into a battery backed non-volatile RAM array for recall. Eight instances of Learner can run at the same time in the Half Gallon Brain. The smaller Pint Brain only ran one instance of Learner, although two were possible.

POWER
The brain is designed to stay on, recharged by a self contained solar cell panel. It can achieve an autonomic sleep state for less power consumption during the night. Power includes sources for processors, peripherals and motion servo motors.

LOADING
The HGB is loaded with a program via a USB interface which is retained in RAM memory via a battery power supply which is solar power recharged. Loading can occur individually or at once with the At Once Loader developed for the Big Brain.

PROGRAMMING
Programming is in SPIN, Assembler, versions of BASIC, and Propeller C. About 250 Propeller languages and their versions are available.

BRAIN BEHAVIOR
When the simple Quart Sized Brain is not texting with humans, learning, thinking, or recalling information from memory, it will spend the remainder of its time sleeping and dreaming.

SLEEP
To conserve power during the night, the HGB will sleep. This uses a trickle of battery power in conservation mode.

NAP
During the day, the solar panel charges the batteries and the brain operates at power capacity. To conserve power during the day, and when idle, the brain will nap.

HGB ANATOMY
This brain uses the high density solderless breadboards, the same found inside the Big Brain. Each HD breadboard fits two Propeller chips with 16 cores. Two 6.5-inch long breadboards are placed back to back and hold four Propeller chips for a total of 32 cores. As each breadboard is 2-inches wide, space is available to mount the power pack, and solar panel on one side and two smaller breadboards on the other side with each holding one Propeller chip. This makes a total of eight Propeller chips and 64 computing cores (see arrangements below). Experiments continue to see if more Propeller chips fit inside the jar.

BOARDS & CHIPS
Center - 2 back-to-back boards, 4 chips
Left Side - 1 board, 1 chip
Right Side - 1 board, 1 chip
Front - 1 board, 1 chip
Back Side - 1 board, 1 chip
Left Side - Solar Panel
Bottom Back Side - Power Supply
Total: 8 chips, 64 cores

SENSORS
Sensors allow seeing and communicating with the outside world. While Ultrasonic eyes don't work well through the jar, light sensitive sensors work great. A couple CaS cell eyes will determine the location of light sources, know day from night, measure light intensity, and process light signals for communications.

THE JAR
The jar is a two quart, half gallon, 64 ounce (net weight 64 oz, (4 pound) peanut butter jar, Skippy Extra Crunchy Super Chunk brand/style. It has a mouth opening of about 3 5/8-inches and a jar diameter of about 5-inches at the mid-section.

OPTIONAL LCD
The LCD is dangle mounted in a clear visible space so data and text messages are easily seen through the clear jar.

EXPANSIONS
The primary expansion is adding capability for the Half Gallon Brain to talk using one of the Propeller chips in a text to speech TTS arrangement.

BRAIN LOBE PROGRAM
It would be highly interesting to dump the memory core of each brain lobe and compare what it has learned relative to other brain lobes. This will require a special program.

DREAMING
The Brain optionally dreams in ASCII based on a random state occurrence which is saved to memory and output to the LCD in ASCII formats. The LCD draws 10mA. The new idea is to record dreaming with a data logging program to upper memory RAM and play it back during the day on the LCD, so that dreaming will remain at the lowest possible power state during the night when the batteries cannot solar charge. This method of saving dreams for playback was experimental with the SEED Supercomputer's ten life forms. (see link)

MOVING
Optionally, the brain is capable of full locomotion and sets up a type of brain/body language. Two servos move two base wheels in robotic motion. Mobility can include conventional light seeking or avoidance and other functions popular with the BoeBot robot. With the light seeker program, the Brain in a Jar will always stay by your side when the light lamp is next to you. Mobility uses its own Propeller chip to control the servos and activate the code based on its enumeration.

JAR'D BRAIN
By July 19th, 2011, the initial Propeller Brain in a Jar was expanded. Named the Jar'd Brain, the larger form jar was introduced, and a series of smaller color coded jars were added. Cap color denoted brain functionality. The design upgraded and improved the jar brain by connecting Propeller chips using sockets, with a unique mounting, thereby permitting pin to pin protection.

Propeller LED Machine

PROPELLER LED MACHINE
From August 26th, 2010
Updated July 7th, 2013
 
The LED Machine is made from one Parallax Propeller chip and wiring with banks of LEDs connected to the chip through 100 ohm resistors (color coded brown black brown) on a 3.3-volt circuit.

The 32 LEDs are on all 32 ports. All eight cores are filled, each core with up to 125 Vprocessors for testing programs. This is a new test board, designed to supplement the Demo Board. It was put together in 20 minutes, mainly from resistors and LEDs. This is the virtue of breadboards. The new board can handle every pin on the prop, and it's decoupled and clock enhanced yet can be rewired in only a few seconds. As you can see, it was decided to have the power supply external to the breadboard. The LED machine's original purpose is to test Vprocessors. Vprocessors were created with this chip in banks for testing from one up to a total of 1,000, with a method to switch banks. After the booting process, all pins on the Propeller chip are available. LED colors are staggered between red and yellow to help identify pins, processors and programs. This works in terms of current draw because not all LEDs are on at the same time. Test programs blink LEDs according to specific unique cycles.

Black Hole Contort Space

Strange Erie Relativistic Space Warped by Temporal Time
FIRST VIEWS OF CONTORT SPACE! 

— INSIDE A BLACK HOLE — 

While other astronomers are focused on the jets from these black holes, the Big Brain Initiative is looking at the very luminous heart’s center, where relativistic event space is warped and the curvature of time is changed by huge gravity. This data can provide information for solving the riddle of going beyond the singularity when space and time was born in the Universe.

In this very deep image, the very distant galaxy 3C348 Hercules A, located 2.1 billion light years from the Earth, is penetrated to reveal the black hole at its core. Next, we used the Power Dynamic Telescope to penetrate further, deep within the black hole and its vicinity.

This image represents a very massive undertaking. The giant Power Dynamic Telescope uses nearly 30 Adjunctives for penetrating deep inside the elliptical galaxy’s core and mining this powerful black hole treasure. This far in, contort space looks strange and erie, warped by temporal time.

The black hole object  has such high gravity that not even light can escape. The image shows matter glow from the mad rush of incoming matter into the black hole itself as it’s crunched into fundamental molecular mush. This black hole was likely formed when a massive star died and its core collapsed into a superdense mass.

PGT-ET Telescope Crab Nebula Test

Stunning image of the Crab Nebula taken with the Lab's most powerful telescope!

TELESCOPE ENHANCED TECHNOLOGY
TEST RESULTS BLOW MINDS!

Not expecting the unexpected... 
The recent result from our new unveiled telescope, the PGT-ET, outstrips our wildest imagination! In the history of our professional work in Astronomy, we have never seen such a highly detailed image of M1 - the Crab Nebula. It's mind boggling and stunning and the wealth of detail was unexpected. See for yourself by clicking above to examine a larger size image. (the full size image is not reproduced here and is even more stunning - and available upon request.)

— the PGT-ET Telescope uses the PMM molecular controls and the Big Brain Supercomputer —

As seen below, a typical image of the Crab Nebula through a modest telescope, captured with a CCD camera, is uneventful and nearly featureless. The image above shows stepping up to the new PGT-ET opens up new worlds!

Modest telescope image

INTRODUCTION
The recent PGT-ET is thought to be the most powerful telescope in the Big Brain's arsenal of scopes. In theory, we expected higher resolution, finer detail on objects, more color, greater image scale, and much deeper penetration into the hidden depths of the Universe. It's design was anticipated to be more ideally suited for the Big Brain Machine's Prime Directive, and exploratory initiative and conducive to learning more about the Universe and what lies beyond the greatest barrier known to mankind.

The Prime Directive
http://humanoidolabs.blogspot.tw/2012/03/prime-directive.html

ICONIC NEW DESIGN - GOING MOLCULAR
Keep in mind, the new design of the PGT-ET telescope has the added instrumentation of the GMM microscope — initially a somewhat novel and ironic idea to attach the devices from the molecular processors onto the telescope. Apparently, according to WYSIWYG, this was a good move and instrumentation to process micro worlds is well adept at processing macro worlds.

THOUGHT PROCESSOR
The telescope is the first to have a Thought Processor, though, for this test, the TP was not utilized. It's currently unknown exactly how the PGT-ET will use TPs for observations. There's some speculation that the actual telescope will become part of the physical observation in terms of quantum thought although the resolution of this issue remains to be seen.

PERFORMANCE
— SIGNATURE PERFORMANCE — Ever since its conception, we've become very anxious to take the new telescope for a test drive and see what it can do and see how it will perform. We estimated performance on a scale of around a 10 percent increase compared to the previous PGT telescope would be possible. In reality, after the first test was completed, the results simply blew us away and outstripped our wildest imaginations, indicating that overall performance is more like a thousand percent increase over previous telescopes like the ULT, NULT, GT, and PGT.

TEST IMAGE NEW DISCOVERIES
The Lab's preliminary M1 qualitative test results analysis

Beginning an elemental analysis of M1, obviation examination by moving from the outer remnant perimeter and settling towards the dimensional inner core, and where the final location of the ulterior realm indicates the presence of the alkali metal element Cesium CS 55 deep within the core (which is liquid at or near room temperature on the Earth). The elemental analysis was achieved by the telescope's new molecular components.

It this case, it's a frozen tenuous material spread throughout the space within the cosmic complex. On the Earth, Cesium is a byproduct created by huge power from atomic and nuclear fissions inside powerful nuclear reactors. Inside M1, Cesium was created by a nuclear fission reaction byproduct from the exploding supernova star. The class of supernovae is considered to be one of the most powerful objects in the Universe.
 
The filamentary structure is far more complex and rich than originally thought. Previously described as containing clouds, it now appears to contain a complex and vast interconnection of intricate and widely varying structures described as connected, island, open ended, with density, tenuity, and both patterned and randomized pathways with particular arrangements and alignments.

The elemental plasma is illuminated by nearby stars.

It appears to contain more filaments than ever anticipated or viewed in the past.

New unexpected and unusual filament structures are visible.

The visual range of spectral emissions is more complex and vast than previously seen.

A new depth of spatial perception and material emanating and migrating inwards towards the core is detected.

The image is far more dimensional, i.e. imagery not only penetrates into the depth of the core but also shows the outer matter mantel.

This data can provide details for many more in depth studies.

INITIAL SITE SELECTION CANCELLATION
Previously we did research to select the largest known volcano in the Solar System, Olympus Mons on Mars, as a test site, with the idea to peer deep into its vast caldron of opportunity and look for new discoveries within the walls of fossilized materials. By the time we were ready for the test, Mars had changed position and the orientation of the OM caldera had changed to an angular geometry that was not satisfying in terms of perceptive depth imaging. Therefore, the OM test was delayed, but not cancelled, and a more stellar and nebular object was selected.

MARS OLYMPUS MONS

SELECTING THE CRAB NEBULA FOR TEST
Why was the Crab Nebula selected for this test?

1) Well known object is easy to make comparisons with other telescopes
2) It's coordinates are well known and it's relatively easy to locate
3) 8th magnitude bright enough for engagement, tracking, testing
4) Previous "discoveries" overlooked with less powerful telescopes 
5) 11 light year dia has considerable depth, perimeter to explore
6) Coverage is within the range of Multiple Adjuncts
7) Geometry is nearly always good for an object of this distance
8) Suitable for the telescope's instrumentation

WHAT IS THE CRAB NEBULA?
The Crab Nebula is a vast remnant of an exploding star that went supernova. The explosion result was so bright and intense, it was recorded by the Chinese, Japanese, and Arab astronomers in 1054 AD. M1 is a key feature in the constellation Taurus the Bull and appears to have stellar matter including dust, various material elements, and nebular gases. It resides at celestial coordinates RA 5h 34m 32s and Dec 22° 0.870'. Distance as determined is 6,523 light years with a magnitude of 8.4.

STAR RICH ELEMENTS VISIBLE
THERE'S NO DOUBT about the variety of colors within the M1 structure as different elements produce different colors. "The filaments are the remnants of the progenitor star's atmosphere, and consist largely of ionized helium and hydrogen, along with carbon, oxygen, nitrogen, iron, neon and sulfur. The filaments' temperatures are typically between 11,000 and 18,000 K, and their densities are about 1,300 particles per cm³."<sup>[11] (source: Wikipedia)

Survivable Multiprocessor Machine

BUILDING A SURVIVABLE MACHINE WITH MULTI PROCESSORS
Can Your Machine Take a Hit and keep on ticking? You know... cosmic ray, project falls to the floor, incoming asteroid, all can upset your precious machine and ruin your day. How can we better ensure the machine will take a hit and bounce right back for more?

At what level can you build a multiprocessor machine which will continue functioning if one or more chips fail? In this blog we will consider some of the ideas required to construct a more reliable machine.

EXPOSED WIRING AND CIRCUITS
Machines with exposed wires and circuit are easily bumped, and oops, a wire is pulled out and the machine no longer functions correctly. Consider when a bump causes a single integrated circuit to dislodge. Another oops. After the machine is built and fully functioning, cover it with microwavable Seran Wrap or a housing containment.

EARTHQUAKE AVOIDANCE
It's almost impossible to avoid earthquakes in some regions of the world unless you move to calmer continents. Unknown to many people, an earthquake often has a rapid vibration effect that can remove paint from walls and ceilings. This high speed oscillatory motion can also effect electronic components and circuits. Pad electronics to absorb oscillations.

SPECIFIC INTERFACE WIRING
The machine with wiring that can continue to function when one or more ICs drop out, is very desirable. To accomplish this, special wiring is required so that the loss of one chip will not hang the interface.

AUTO CHIP REPLACEMENT
Both wiring and software must work together to accomplish the Auto Chip Replacement method, where some unused chips are standing by, ready to fill in for failed chips.

DIAGNOSTICS
On the fly diag is highly useful to determine the stats of each chip. This can be run at power up, mid range, and power down. The trick is to find a test algorithm that functions very effectively and very quickly. Remember, the time required to run the test is multiplied by the number of chips and the number of cores. For a 100 chip machine, this equals 800 cores. If the test requires one minute per core, the test will finish in 800 minutes or 13.3 hours later.

Multiple Processors Over MultiProcessor

MULTIPLE PROCESSORS OVER MULTI PROCESSOR
One question that has arisen in this field is, "Can you do more with a multiple processor machine with many chips rather than a machine with a single chip that contains multiple processors?" This notion divides into more considerations. Is one more flexible over the other? Which is more cost effective? Which is easier to program? Which can help solve applications in a faster manner? Which one has better hardware? Which is the better controller? Which one  has more I/O pins? Which is faster to troubleshoot? Which is more repairable? Are all processors useable? Which is easier to to use in constructing a machine? For these questions and more, let's build a machine and start our comparisons.

For this study, we base our answers to questions by comparing
two actual brand chips, the GA144 by Green Arrays and the Propeller by Parallax. We will create a Propeller machine with the closest number of whole cores to the GA144 chip with 144 cores.

Note: In this comparison, in each category, the processor winner is in parentheses.)

NUMBER OF CORES
Each Propeller has 8 core risc processors. 144 processors is equal to 18 Propellers.  So we will compare a one chip machine containing multiple cores to a machine with multiple chips and multiple cores. All chips are different in one way or another. Let's focus on the questions. 

INPUT OUTPUT PINS (PROPELLER)
First up, which one has more pins for input output? The Propeller. Each chip has I/O 32 pins. With 18 chips, the machine will have 576 pins. The GA144 has 88 pins with only 25 for I/O.

HARDWARE (GA144)
Which chip has more hardware? The GA144 offers more built in hardware.

FLEXIBILITY (PROPELLER)
Because the design of the Propeller uses software to create hardware, it's more flexible.

NUMBER OF LANGUAGES (PROPELLER)
The GA144 has one language to the Propeller's over 248 languages and variations.

AS A MICROCONTROLLER (PROPELLER)
The Propeller machine as a controller has full access to more I/O pins.

USABLE PROCESSORS (PROPELLER)
Unfortunately the wiring of the GA144 does not permit all processors to be used at the same time for some apps. With Propellers, all chips are up and running, and all cores have access paths.   

WHICH IS FASTER? (PROPELLER)
The GA144 would seem faster at first. However, the Propeller is faster when the speed of all 18 Propeller chips and 144 cores are added up. 

COST (PROPELLER)
The GA144 is $20 per chip but you are forced to buy a minimum of ten chips. The Propeller is $7.99 each or $143.82 for 18 chips with 144 cores. Because, to get one GA144 you must buy ten, the cost of one GA144 chip will be $200. The Propeller is more cost effective. Also when the Propeller machine has a chip go out, if it ever does, the chip can be replaced and the entire machine is still usable. This makes the Propeller more cost effective because if a single core goes out in the GA144, the entire unit must be replaced.

EASE OF PROGRAMMING (PROPELLER)
The GA144 has only one language - FORTH. The Propeller has options with over 248 languages and their variations. The Propeller is significantly easier to program because it has more programming options, more flexibility and you can choose your favorite language for programming to make things more easy.

MORE REPAIRABLE (PROPELLER)
With the propeller machine, if a chip fails, just unplug it, remove it, and insert a replacement with the handy DIP configuration. With the GA144, the entire chip must be replaced.

TROUBLESHOOTING (GA144)
Which chip is faster to troubleshoot? There's an edge advantage with a single GA144 chip not working. Just throw it away. No need to test other chips.

EASE OF WIRING (GA144)
The GA144 is already permanently wired inside the one chip.

SPECIAL WIRING (PROPELLER)
You can wire in between the chips of processors which is not possible with the GA144.

SUPPORT (PROPELLER)
As we see, and based on the Forums given, the Propeller appears to have ten thousand times more support in terms of the individuals using the product around the world, and with the support offered by Parallax Inc.

CONCLUSION
We looked at 15 comparison points. The propeller wins over the GA144 in eleven points, while the GA144 holds its own in 4 categories. We therefore conclude that for our purposes and for the purpose of this analysis, the Propeller chip, and the technique of using multiple Propellers is superior.

We also believe the GA144 is a very useful, advanced and powerful chip with many potential applications. It may very well win over other processors in other areas not considered in this study.
