Since today (11/11/11) is the last 6 digit binary date this century, I thought we should look at some kinetic binary calculators. Matthias Wandel built a beautiful 6 digit binary computer out of wood. If you want to build one, he even gives you some more information and instructions, plus the plans.

Virtual Mechanical Adder. One day I found this amazing marble binary adding machine browsing around. I want one, but didn't have serious woodworking tools lying around. So I created a simulation of it. As this is a 6-bits adder, it will overflow on number greater than 2 6 - …

Jan 21, 2012· Sometimes we were surprised by the various people. There was the 5 year old who could tell his mum "look I can do 1+1 with marbles and it says 2" as well as the grandmother who knew binary from her teaching days and was staring, eyes wide open, at the machine. And of course, it is still a marble run. Everybody loves marble runs!

5 in binary is 8*0+4*1+2*0+1*1 so 0101 7 in binary is 8*0+4*1+2*1+1*1 so 0111. So if you want to input 5 into the calculator, You DON'T put a marble in the left most input You DO put a marble in the second left most input You DON'T put a marble in the third left most input You DO put a marble in the fourth left most input So that one marble represent a 1 and no marble represent a 0.

A binary adder is easy to understand to the modern mind; for each bit you can use an XOR for the result, and an AND for the carry. But what about biquinary? how does 7 + 3 work out as 0 + carry, or 2 + 3 work out as 5, or 1 + 1 = 2? Another way to phrase the question: What …

Nov 19, 2016· A 4-bit Calculator made in cardboard and marble. 0. LOGIC. ... You place your input numbers as binary in the inputs, a marble is a one, no marble is a zero. The bit on the right is the least significant bit. You have to reset some part of the calculator before each calculation too. Then you remove the little bit of cardboard that kept the ...

This is the beauty of working in binary, it reduces arithmetic to logic. However, a half adder isn't enough because you might have a carry from the previous bit position to add in. You can build a full adder from two half adders and this is the way most people choose to implement a full adder…

Nov 22, 2010· You wouldn't take this calculator with you to a math test, but it does a fair job of adding up numbers — if you don't mind entering your calculations in binary. This calculator uses marbles and ...

The retention of this extra marble allows the state of the marble accumulator to be dumped. The adder would just as well add without it, but the number would have to be read off by the angle of ...

For fans of the metric system: a height of 58 cm, 46 cm wide and 25 cm deep. Operates with values up to 1024, and can count and multiply, as multiplying can be seen as repeated counting. ...

Here's a YouTube link to a wooden Marble Adding Machine.It helps to visually see how adders work together to add binary inputs. A half adder takes two binary inputs -- A and B -- and generates two outputs -- the sum, S, and the carry, C_out.

Building the marble adding machine This is based on an article I wrote for Make magazine at their request in early 2008. An article based on this content was published in Make Magazine issue 20 in late 2009 - more than a year and a half after I submitted it to them.

But then I had an idea as to how the divide by two mechanisms from my first marble machine could be cascaded together to function as a sort of adder register or counter. Once I had that idea, I knew I had to try it. A few months later, I spent a couple of days in my workshop and built this binary marble …

Jun 22, 2007· But a few months ago, I had an idea as to how the divide by two mechanisms from my first marble machine could be cascaded together to actually function as a sort of adder or counter. Once I had that idea, I knew I had to try it at some point, and recently, I finally got around to building my marble binary adding machine.

It does, however, make it easier to build machines that can add as we saw with this gravity powered marble binary adder. We compared this to the Curta mechanical calculator which operates with 10-digit numbers. September 6

ndogg writes "This story is all wet. Paulo Blikstein at MIT has created a water computer. The one boolean logic gate he created functions as a half-adder (i.e. both XOR and AND). He then proceeded to create a four bit adder…

The basics of any calculator lies in the ability to perform binary computations. Binary is a different way to represent numbers. Since we have ten fingers, we count in a decimal system. We count from 0 to 9 and then start again from 10 to 19. We count by groups of …

You'll learn a 'bit' about binary numbers (the foundation of all computer operations), have hands-on time programming marble driven computers for gaming, math, and problem solving, and use a marble-based binary calculator to perform simple addition.

In the preferred embodiment, each of the binary ripple adders are replaced by a smaller-scale version of the hybrid adder itself. The hybrid adder can also be configured to add two 56-bit operands, which is ample for performing summation of the 52-bit mantissas …

However, by combining two half adders, one can get a full adder, which in turn can be cascaded to produce a binary adder of any size. The pictures above show the LEGO half adder in its four different states, where A and B are the inputs, S is the sum and C is the carry bit. There is also a video available of it being operated.

Dec 18, 2012· For maximum marble action, add 63 (111111 in binary) to 63. It's also fun to use the adder for subtraction and negative numbers by using the two's complements of numbers. This means interpreting the leftmost bit as the positive or negative sign, and flipping all the other bits to convert from positive to negative.
