Brain Cortex Power Mounts Part 42

CORTEX BRAIN POWER MOUNTS PART 42
THE BRAIN IS POWER HUNGRY
The brain cortex in a jar power mounts consist of eight battery holders mounted directly on the inside jar. The mounts are four hardware assemblies to a single battery holder and include a half inch spacer, nut, bolt and three sealing washers to each. Thus far, the single battery holders are stacked twins. The jar has four geometrically mounted twins.

The 32 holes in the transparent polymer jar are not drilled but rather made with a hot soldering iron to do the melting. This is the best approach considered as hot glue would damage the jar, a mechanical drill is prone to scratching the jar, there's no easy method of scoring the surface for drilling, and a punch can easily tear the substrate.

Each assembled power unit is held in position inside the jar and from the outside, a hot soldering iron melts a tiny dot over the spacer end. The power unit is removed and the four holes are melted into the jar. Then, the power unit is mounted on the jar and process is repeated for seven others. (see illustration)

JAR CAVEAT
Be careful when handing the jar so as not to scratch the surface. As the jar is made of soft flexible plastic, it can easily scratch.

Brain Cortex Part 2 - the Jar

BRAIN CORTEX PART 2 - THE JAR
PART 1 Work continues on the Brain in a Jar series of projects, this time with a single Parallax Propeller chip and larger one liter jars. Parts were purchased from the electronics stores and jars came from the grocery store pet section for rabbits (seriously), Costco (peanut butter section) and the dollar store (although ironically everything cost more than a dollar).

Did we buy rabbit food to get this jar??!!

LEFT: Jar dilemma, what to do with the rabbit food?

Non-glass jars are relatively inexpensive, more safe from breakage, cost no more than US$3, and are made of durable transparent polymer.

The cortex can communicate to the outside world through the transparent home jar with a choice of light sensors, protruded wiring, or transmitters. The battery pack is also rechargeable through the transparent jar with solar cells.

We ate peanut butter to get the peanut butter jar but we doubt we're going to eat the rabbit food in the rabbit food jar. Anyone have a rabbit?
