Introduction: Pi/Pie Clock - Pi Day

This clock is best for geeks and nerds who want a clock which shows their nerdy side. The clock uses representation in the form of Pi to represent the numbers. The value of each representation is approximately equal to the value of each number.The clock looks cool and can be made as you like. Mine looks a bit ghetto but with a little more work perfection can be achieved.

Step 1: Things Needed

The materials required are:



1. An old clock, a new one if you are up for destroying it: I used an old clock and placed a new dial above the older one. This is not the only way. You can also make your own clock, use the machinery of an old clock and build a new housing, or anything that you can think of. Let your imagination run free.
2. Thick Paper or Photo Paper: If you are the artsy kind you can use thick paper or any paper and draw the whole dial on it or if you are the computer kind, you can make the whole thing in a photo editor and print it out on photo paper. I used the drawing method for the base and printed out the decorations because taking measurements and making the dial of exact diameter was much easier by drawing.
3. Markers and other drawing equipment.
4. Geometry stuff(Compass, Scale etc.) to make measurements .

Step 2: The Process

The Procedure was as follows:



1. Open up the clock, remove everything and take measurements of the dial. Diameter if its a circle, edge length if its a square, etc.
2. Now I used the drawing path because printing something that has a specific diameter was a hard task.
3. Using a pencil. Draw a circle, divide the circle into divisions of 30 Degree each and for decoration I made kind of a pie in the center.
4. Draw the pi equations where the numbers should be. You can check out all of the equations in the photo above.
5. Decorate as much as you want. I am bad at art so this was the best I could do. Write over the pencil markings you want to permanent by a marker.
6. After realizing my artwork was very very bad I printed a pie on a photo paper and stuck it in the center of the dial to make it prettier.
7. Poke holes in the middle of the new dial and put it on the clock.
8. Reassemble and you're done.

Step 3: Ideas

This project is just for fun and can be made in millions of ways

A few ideas for you



1. Use an old clock machinery and a CD. You got yourself an easy to work with clock with no diameter restrictions.
2. You can use LED's and an Arduino to light up the pie or anything you like at 3:14.
3. You can make it using other equations as well

This is... Clever, but very wrong. At the three o' clock position it should at least be pi-.1416 or something close. Some of these you need to round down even when you should be rounding up because the decimal is greater than .5, and vice versa.

I wrote in the introduction that these are approximate not exact values. For the rounding off problem its only because I couldn't find small equations that were much nearer to the exact values, but at max the values go don't go very much above .5 . It's only because I couldn't make up anything better and smaller.

I see. I didn't read the introduction very thoroughly. You never truly can get whole numbers from constants, unless you subtract the constant from itself(and other things like that).
