    If the prop chips are mounted on a concave board, the curvature, if too much will run into pin length limitations. That's why the polyhedron ( platonic solids) suggestions are best. If you had two props per facet one on the inside of the polyhedron facet, one on the outside, the inside props could handle the facet to facet communication while the outside props could deal with external I/O. If you nested icosahedrons then the prop density could be additionally increased while still using planar circuit fabrication methods. If pushed you could add enough fiber optic communications to ensure plenty of bandwidth.

    A reason for going prop intensive is to effect maximum I/O and control in as small a volume as practical. For the moment the heating problems have been sidelined.

    Swampie777's idea of "props on both sides of the PCB", is an interesting one. Consider using 12 pentagonal PCBs to form a dodecahedron with Props inside and out. Using one "face" as the base, that leaves 11 faces and 22 Props (not an ideal number)·to integrate.·A lot of the interconnection mess would be hidden on the "inside" of this kind of 3D sculpture (Yes, the heat problem will have to be address eventually).

    Respectfully submitted,

    He was talking about using optical communication. for that the best layout is everything on the outside with no solder mask silver plated bottom. silver oxidizes so you would need to protect it with something though. gold could be used but would bring pcb cost up about $100 for the sphere.

    If the curved shape is large enough, the section under the chip mount is not a problem and was already addressed in an earlier post.

    The first board is successfully working quite well and is being refined. Some additional ways to do conductive path etchings are being investigated. These are now made manually, one at a time. I can envision a robot system to deposit the pathways automatically. Now, work is progressing on a second multi dimensional printed circuit board based on a chemical approach to hold the path etchings. There are now two projects going on at the same time if you are following this thread. This second board can also take on various curves and shapes from its original mold, like a shape shifter. It is a chemical board currently based on one mix.

    This may be the first chemical multi dimensional board. I will let you know how successfully it works on a larger scale. Don't get your hopes up - it could fail on the larger scale. However, on the smaller scale, the little model is successful. I am waiting to try another larger shape. Today I am molding one smaller dimensional shape for another clarity test, and then will go with the next larger 40ML dimensional board. Another test area will be the propagation of communication in layers through the substrate. As it dries, the properties are notably changeable. If there is a diffusion effect, the amount of permeability will come into play.

    Multi Dimensional Hyper Curve Chemical Printed Circuit Board for New Hypercomputers
    Casting of another chemical dimensional printed circuit board was accomplished tonight. (the use of "printed circuit" is loosely used) Two more are setting and will be put into use tomorrow. The photos shows the boundaries of a dimensional hyper curve, a continually deepening hyperbola to which there is no recovery at its apex. A board like this is used in the new Humanoido Hyper Computer HHC design which is made up of Parallax Propeller chips.

    The photo is probably not the best due to the limited lighting, but it's the main one showing the degree of the curve. Since the form is little, as the chemical material was only around 40 ML and had to be divided, the focus was in closeup mode. I have attached another pic which shows more and can give some more points of reference.

    As you can see, it's a very nice curve and achieves the original goal well.

    Chemical Mold Set Time

    I checked two of the new molds today and after 24 hours the chemical has only partially set. It's dry to to the touch on the outside but clearly still setting on the inside. I'll need to give it another 24 hours to dry. In the mean time, I will make some improvements to the first board design which is not chemical mold based.

    Some results of creating chemical multiple dimensional printed circuit boards... The recent chemical results are in and appear promising. After 48 hours, the material is mostly dry, though there is some shrinkage inside the mold. One of the shrinkage's caused bubbles that broke on the surface. In one form, the convex shape became concave, and in another form, the concave became convex. Obviously the material is drying from the outside in. This technique can be exploited when shaping the bord during the drying process. While the material is translucent, it is simply too opaque to run communications. The next test is in progress. A larger mold is being created for another chemical. The idea here is not to let the material dry out. So maybe you will need to keep these boards in the refrigerator for storage. Meanwhile, all the tests and prototype for the first "non-chemical" boards are working. After this week, a decision will be made for which board to use.

    Note the anterior is entirely suitable for Propeller chips and traces. The opening gains access to the posterior although this is simply not the caudal end of the form due to its multi dimensional structure.

    @humanoido: Look at the NKS forum and Stephen Wolfram. Tell me, are hypercube supercomputers equivalent to
    or transcending a universal turing machine? I would suggest that a one-dimensional computer program could emulate
    time sharing multithreading, why not just run each instruction in a hypercube VM on one propeller. It might be slower
    than a hyperspace array of them but should produce the same results. Here are some other artifacts I have designed:

    A computer-rendered hologram of a spatially 4D object. If necessary, it would be exposed in a sphere.
    If the hyperspatial polytope image is mirrored,
    then that might be a working crystal ball that reflects orthogonally to beyond all 3 dimensions.

    A tesseract shaped electromagnet. I have built a tesseract that has equal length edges in 3 dimensions.
    The proposed electromagnet would be wired in a hamiltonian path, or switched rapidly so that each cube face,
    or more of them, or all of them, are powered in some order so as to make a rotating 4D motor field winding.
    I have demonstrated the tesseract-cube sequencing with luminous EL wire. Google "instructables viron tesseract".
    Not having wound the whole 4D electromagnet, I have no idea how it would behave, and if anything unusual
    happens, it probably would only be observed if the electromagnet was vaporized to plasma by hundreds of amps
    within a millisecond of being powered on. Expected to expand outward and vanish, the plasma could stay in place
    and continue working as a 4D electromagnet, or implode, if I'm wrong. It may produce ball lightning or some never
    before seen shape of plasma. Who knows, it could even become a black hole or wormhole. It could leave behind
    a permanent field of some kind... imagine if iron dust in the air began accumulating into spheres where it vaporized,
    which just stayed there for a while until some kind of standing wave of magnetized time dissipated.

    And of course a Propeller could be used to render the 4D hologram,
    or apply multiphase currents to the windings of the electromagnetic tesseract.

    The Propeller can do anything. Anything you tell it to do. Anything you know how to tell it to do.

    No computer, regardless of its topology, can do things a Universal Turing Machine cannot. Other computers can do things faster, certainly; but, given enough time, the UTM can do anything the most powerful supercomputer can do. That's why it's called "universal".

    VIRAND: Absolutely yes, a multi dimensional hyper cube supercomputer can be simulated inside Propeller chips. It will function with a more dilatory time frame than if built from actual hardware - this is the nature of VR.

    Before beginning with hardware, I visualized a VR with a multi dimensional curve spread across the multiplicity of cogs. But since I wanted the prop chips (and cogs) attached outside of VR, decided not to go this route, this time. That will give me some time to develop a greater repertoire of programming first, before diving into the indelible water.

    I think they were planning to see if a micro graviton was created or a tiny black hole, using the new accelerator. Has anyone heard from those people since that experiment? [noparse]:)[/noparse]

    The 4D electromagnet is an interesting project and perhaps you can proto it, and relate it to a Prop chip and post more information about it. However, to punch an actual hole into the fabric of space time, it will require a tremendous amount of power in the form of some energy such as gravity far greater than what the Earth provides. You could plug some values into Einstein's or Hawking's equations to see if the transformations take place to create a micro black hole or worm hole. You may need some special equipment to observe the actions. You will also need to create one so small, that it won't have any adverse effects. Is that possible?

    Can you create a reflective (in that manner of reflectance off the actual surface of the hologram's parts) hologram? When we made holograms in Physics class, a hologram was "a negative produced by exposing a high-resolution photographic plate, without camera or lens, near a subject illuminated by monochromatic, coherent radiation, as from a laser: when it is placed in a beam of coherent light a true three-dimensional image of the subject is formed." If we can get light to reflect off the actual hologram, then we can create real world interacting holograms, right out of Star Trek.

    It was a shopping day for more chemicals to try out on a multi dimensional printed circuit board. However, later I did some shopping at the grocery store for food, and I found some Gelatin on the shelf (very surprising), which was quite expensive oddly, and some jello, which was nearly the same cost. (Jello has the same content - some Gelatin, coloring and sugar added) As I looked more carefully, there was a flavor that no one liked (it was lemon), and it was marked down in price, and it was nearly double the weight content amount of the other packages - a bonus. With tongue in cheek, I bought it, but not to eat it. If I remember correctly, at Christmas time when I was little, a tiny jello package could make an entire large bowl of Jello (Is this correct?) and it took on the exact shape of the mold. It also has other benefits of transmitting light. Does anyone remember how long it keeps?

    The current test mix makes 4.5 cups using only a 3.4 ounce box of filling. The filling sets in only 5 minutes which is advantageous, however, this particular set mix of a filling is relatively opaque. The material holds a formed shape that easily allows multi dimensional routing of conductive trace materials which is set by the amount and concentration of added gelatin base. The stability of the material is also under test. Thickening in some substances is achieved by adding Disodium Phosphate and Tetrasodium Pyrophosphate. Foaming is prevented by adding Mono- and Diglycerides.

    In the past I had cast a set of telescope mirrors and lenses using clear resin and a machine to spin the form resulting in a parabola shape with gravity and inertial effects. A resin with similar clarity could better serve the purpose of multi dimensional printed circuit board that has requirements of transparency and rigidity of embodiments inclusive of trace patterns and components. (It's a material with greater durability and stability, and likely to hold its shape a longer period of time, and no need to refrigerate.) A similar machine with various rates of spin motion could impart various shapes and curves ranging from oblate spheroids, spheres, parabolas, and hyperbolas, etc. By inducing degrees of off-axis tilt, numerous new shapes are possible.

    or you could make a mold out of jello and put the resin over that.

    It would be relatively easy and inexpensive to create molds out of Jello, with some considerations.

    1) The mold is flexible and not rigid, therefore the hardening material must not resist the form
    2) Jello has life expectancy therefore the drying material must complete its cycle within a time frame
    3) Molding materials must not be heated or release heat or the water content in jello may be affected
