NOT!

Here is a kit, for assembling an Analog Clock (displaying  Binary Numbers). 

                                                   WOW!

The 4 main numbers on the old fashion (analog) clock face are 3, 6, 9 and 12.

Your clock will help you advance from knowledge of the familiar DECIMAL (10) 

numbering system to the BINARY (2) numbering system (used by computers & your clock).

          Decimal (base 10)                                    Binary (base 2)

          10   1                                                         8  4  2  1

           0    3                         same as                  0  0  1  1

           0    6                         same as                  0  1  1  0

           0    9                         same as                  1  0  0  1

           1    2                         same as                  1  1  0  0

For an explanation and for further exploring, take a look at:

See the blog ‘Magic Cards Explained’ (above in the recent posts list) for further exploring:

Be sure to see the Turing Tumbler count to 20.

You can Download & Print the page containing the cards, creating a very nice magic trick for yourself.

Enjoy exploring magic, numbers, clocks and computers!

I hope that it will help make the transition from Decimal numbering to Binary numbering easy.  And to excite and stimulate them to self educate in the world of Binary mathematics.  This knowledge will serve them well in the computer sciences.

Here is how you could make an Analog Binary Clock:

First read and understand the information above.

Go to website https://www.thingiverse.com

Search for ‘GeeEaZy’ then select ‘Binary Clock’

            (This is my Analog Binary Clock Face design)

Download the .stl file.

             (This is what your 3D printer software wants)

             (Once downloaded the .stl file be among your downloads for today)

Run your 3D printer software and submit the .stl file for slicing and rendering

             (select filament color – scale for size – other adjustments)

             (a .gcode file should be created to be sent to the hardware 3D printer)

Close the thingiverse page to return to this blog

Go to amazon.com or other commercial source and buy:

            A clock mechanism with a short shaft (less than $5)

Install Clock, with AA battery, per these instructions.

Here is a extra puzzle of more Binary numbers that might be added to a clock face … :
