Printing Inside the Brain


What are brain printed objects? Tell the brain, instruct it, and internally it will print an object that exists only inside the brain. What you can do with this object is where the fun and fireworks begin.

The process considers using a Parallax Propeller chip and its internal components to achieve a new kind of three dimensional printer, inside the chip.

GETTING STARTED The Brain Printing idea is limited to the internal world of the chip. Previously, tiny machines, some of nano sizes, were created inside the chip. These used the existing parts and components internally and combined their functioning with both hardware and software. How can these constructs be used to create the object we want? Is it possible to use a combo of hardware, software, firmware, to layer an object of choice?

STEP BY STEP First, one must examine the available resources and then decide what functions are possible in the internalized printing machine. The Big Brain is comprised of chips where this process will take place. The first object to consider is a square of deposition material, and the first question regards, "What is the composition of the deposition material?" Since the deposition material must include a "memory layering," it's likely there are several options for use. For example, one could deposit layers of different physical elements, such as the effects of magnetism, frequency, current, infrared heat, specific types of radio waves, period of oscillations, and voltage or amount of charge. The device can also involve the use of traditional components such as ROM for reference points or concatenation of specific values and elements, or a build up of memory cells and registers.

For this project, SPIN software is the programming language agent. The finite sides of the square are represented by a mathematical matrix. The matrix is extruded along one axis to make a geometric cube which is the first object internalized. This is analogous to programming the CAD model in a computer before the item is printed if a conventional 3D printer was used. Here, a kind of CAD model is internalized inside the Propeller chip using a few tools that must be developed, such as the mentioned matrices and mathematical models.

Once the model is complete, it can be brought into real world by virtual representations for study. The video generator is a good tool to make this happen graphically on a TV using NTSC 1V p-p standards. The Propeller built in TV generator is easy to use and several examples are found at the Parallax web site. Only a few resistors need to be added to the circuit to make this happen. The remainder is software to draw the screen representations. Another programming language for drawing images on the screen is LOGO. Information about a propeller version of LOGO is found at this site.

The next step is to create, or print, the object inside the chip by the layering method of printing. The printing agent is the unique key to process and is based on the choice of material. Experiments are performed in the layering of various physical elements mentioned. See the list of Layering Physical Elements.
