To prepare each of the ten D-size battery holders, obtain phenolic washers, 3/16th-inch long brass spacers, and bolts. The spacers are the shortest size that will allow a bolt to fit with 2 washers. Each holder has four holes. The project will need 40 spacers, 80 phenolic washers and 40 bolts. Insert a bolt, washer into each mounting hole, then add a washer and screw, on the spacer. Repeat for all forty holes in the ten battery holders. Loosely tighten.STEP 2
Loosen each spacer and bolt, and move it up as high as possible, farthest to the edge of the battery holder, then tighten. This will ensure all battery holders have spacers in the same symmetrical place. Now tighten each bolt into the spacer but not too tight or the plastic holder could break over time. You want it snug but not too tight to cause undue stress.
The next step is for the next part installment, mounting the holders inside the jar.
NEW DESIGN
The holders will now rest at the bottom of the jar to provide stability. It was decided that mounting heavy D size batteries solely on the side of the thin plastic jar without any additional weight support would unduly stress the jar wall and possibly cause damage (flexing, warping, cracking, tearing, stressing). With part of the bottom of each battery holder resting on the jar floor, a portion of the weight is distributed and wall stress is reduced significantly. This causation will result in a desiccator redesign.
BACKGROUND
The circuit is designed to run on 3 volts. Each holder will hold one 1.5-volt battery. There are ten holders which will series connect in twos to provide 3 volts. Batteries are 1.5-volts each. The 5 series connected sets of batteries will connect together in parallel.

ABOUT THE MACHINE CORTEX BRAIN PROJECT
The project objective is to develop a cortex machine brain, demonstrating human-to-machine brain transfer, in particular to take some relatively simple human characteristics and transfer portions to the machine brain, whereby human traits could be given greater life longevity, leading towards immortality.
