Additional CAD components

I am using autocad fusion 360 to model additional components.

Here is an animated model of a switch:
 
  And this one is a bit more complicated, a 'stop':
Ryan 3D printed some of the base components for me. Here is the main piece of the 'stop'.

The part is so small that the channels are not very clean. Ryan also said he wouldn't be able to get great resolution on the 1 mm thick moving part. He suggested that we use his CNC to mill them out of wood or plastic instead.

I think my initial design of the 'stop' is too complicated. It would also be nice if all the components would lie flat on a board. My friend Justin drew a picture on a white board that showed a trigger to stop and release marbles. Here, a marble gets stopped on the left channel until a marble comes down the right and hits the trigger, releasing the marble on the left.



I also think I would like to use some micro bearings and maybe machine the moving parts out of aluminum. Also I have been doing some research and I don't think my 'switch' CAD design is good, so I plan to make some alterations or redo it.

Could I machine an entire AND gate out of a wooden board? It has me thinking.

Marble Computer Language

In symbols one observes an advantage in discovery which is greatest when they express the exact nature of a thing briefly and, as it were, picture it; then indeed the labor of thought is wonderfully diminished.   - Liebniz To build an AND gate, we need some smaller components. We also need a language to talk about the smaller components. 1. Consider a marble run component with one input track and two output tracks. If a big marble is put into the input track, it comes out on the left output track. If a small marble is put into the input track, it comes out on the left hand track. We call this component a Separator. We use the following symbol, an inverted Y with a double hash to denote which side the big marble comes out:  | // \ 2. Consider a marble run component with one input track and one output track. The marble going into the input track comes out of the output track but is delayed. We call this component a Delay with the symbol: Z 3. Consider a marble run co

Marble Separator Prototype

He is ready to separate the chaff from the wheat with his winnowing fork. - Mathew 3:12 I like to define the ones as wheat and the zeros as chaff. I need to build a winnowing fork to separate the marbles for operations like sorting. I have a couple of landscaping pitchforks in the garage with tines the perfect distance to separate 'shooters' from 'cats-eyes', but they are way too big to go into a computer and I need them to spread wood chips. Recall that we defined a separator as a component that takes in a marble and routes it one direction if it is a large marble (wheat) and routes it another direction if it is a small marble (chaff). Here is a youtube video of my first separator made with popsicle sticks and glue: Eureka! I've done it! This is the first of my components to build my marble computer!! And it's pretty small, only about 3x2x6 = 36 cubic inches. With only 8 components in an AND gate, an average gate might be 288 in^3. Then a full adde

Initial Musings

I want to build a computer out of marbles. I told a few people about this plan and they look at me like I am crazy. What do I mean by making a computer out of marbles? Modern digital computers take in instructions called 'programs' and execute them by running electricity through specialized gates. The results are then usually either returned or stored. Instead of running electricity through electronic gates, I intend to run marbles through mechanical gates using gravity to the same end (albeit slower and smaller). The 'DigiComp II' and the 'Rule 110' marble computers are already built, but I will be doing something a bit different than those and other marble computers I've seen. My computer will use 2 different sized marbles for 1's and 0's and not store all information in the marbles themselves rather than the state of the machine.
