Brain Cortex Jar Study Part 54

BRAIN CORTEX In the forth corridor, the spirit thermometer bisects the compartment making space for dual desiccators at this location. The jar has three remaining full size dessication compartments created by the corners of mounted power units. The jar study verifies the necessity of a sizable desiccation system. After the jar is hermetically sealed, RH will settle although the temperature may fluctuate based on the external temperature variance and heat given off by the internal energy source.
BRAIN CORTEX JAR STUDY PART 54
As work progresses on the construction of a brain in a jar and electric devices are coming together, experiments are conducted on the atmosphere occurring inside the jar.

With the jar kept a bit ajar on the lid, the temperature and humidity are monitored without the Desiccator Unit in place. As the temperature drops below 70 degrees Fahrenheit, we see the RH shooting up to 65 without any indoor climate control in place.

High levels of humidity are to be avoided inside the jar to prevent any surface sweating condensation and resulting corrosion, and as a result of this study, the jar will received a Quad Desiccator to bring down RH.

It's recommended to keep the jar sealed, activate the QD, and monitor the internal temperature particularly during charging to prevent any overheating conditions.

Desiccators can be removed for dessication recharging, by removing heat safe chemical crystals in the container and baking the contents on a metal pan in an oven to remove their moisture content. Instructions are on the web and follow all safety precautions.

The QD will reside in the four remaining corners produced by mounting the Power Units. In the fourth containment, a space bisection results leaving two narrow vertical corridors which are perfect for mounting cylindrical desiccators, one one each side of the spirit thermometer.

The QD is currently under construction, mainly involving a large collection of the dessication chemical. The dessication chemical is free by scrounging assorted sources and packaging.

Brain Cortex Desiccator Part 24

The jar floor design is curved to strengthen the jar. This forms an ideal shape for creating a jar desiccator. The top plate is bolted to the apex and the plentiful underlying perimeter space stores numerous bags of free desiccant. The jar bottom indentation prevents the bolt from touching or scratching the surface of a table where the jar is setting.
BRAIN CORTEX DESICCATOR PART 24
Nearly every large brain cortex in a jar needs a desiccator to prevent or remove moisture from internally forming on the walls when hermetically sealed.

DESIGN
The Desiccator design is completed and makes good use of the existing 3-liter jar floor design. As seen in the photo, the floor is curved in the upward direction with a sagitta of about .75-inch. (In geometry, the sagitta of a circular arc is the distance from the center of the arc to the center of its base.)

DISICCATION PLATE
A desiccator plate is fabricated from transparent cut into a disk of maximum diameter that will fit through the jar opening. A hole at the center accepts a mounting bolt. Under the plate, bags of free desiccant are distributed.

FREE DESICCANT
Free desiccant is obtained in large bags found in large bottles of Centrum (310 count) and other vitamins. Numerous other products include desiccant bags and these work too.

BATTERY ARRAY
At the plate perimeter is the array of battery holders, mounted flush with the plate. The combination of the battery holders and the plate holds the desiccant in place.

PLATE REMOVAL
In the updated desiccator plate design, the diameter determines a perimeter that meets the battery holders but does not extend under. The facilitates easy plate removal for changing desiccant without the need to remove the battery holders.
