My first ever Instructable. YAY!

This instructable is for building an LED night light cube.

You will need the following supplies/ tools:
bristol board
tape
felt
embroidery thread and needle
LED (brightest you can find)
scissors
glue
2 3v coin cell batteries
wire /wire strippers
pins

Step 1: Measuring the Cube Pattern

Step 1

Using a ruler, measure, and trace 6 connected squares on the bristol board.
Each square is 3in x 3in, so the long center part will be 12in wide  x 3 in tall, while the shorter cross section will be 3in wide and 9 inches tall. 
Once you've measure and traced the pattern, cut it out.  Using the ruler to create a straight fold, make a crease at each 3 in mark. 
Your paper should look like this image.

Step 2: Cutting Out the Backing for the Circuit


Step 2

On a completely separate piece of bristol board, measure a 2.5in x 2.5in square.  Measure in half an inch from the bottom and left sides, and cut a square that the coin cell batteries could fit inside.  Your paper should look like the image.

Step 3: Cut a Circle

Step 3

Using the Xacto compass, cut a circle in the bristol board that measures approximately 1.5 inches wide.

Step 4: Making the Rotary Switch

Step 4

Using a pin, poke holes in the center of the circle, and near the outer edge. It should look like the image.

Strip a piece of wire, so there is no insulation on it at all.  Run the wire through the two holes that are not in the center of the circle. Twist the wires together to tie them off.  You should have a piece of wire that creates a line on the back of the circle, and the twisted end of the wire will be on the front of the circle.  This line of copper wire, will create a contact between two points you will create in the next step.

Step 5: Creating the Circuit

Step 5

Place the circle in the upper right hand corner of the 2.5x2.5inch piece of paper.  If you need to, you can trace an outline, to remember where it is.  Using a pin, poke a hole where the center of the circle is. There should be a hole in both the circle, and the paper behind it.  Then poke 4 holes, like the points of a tiny square, underneath the copper wire in the circle.  Stripe two pieces of wire completely, so there is no insulation on it at all.  Run one wire through two of the four holes, and the other wire through the other two holes  The wire should create two lines perpendicular to the wire in the circle, so that when the circle rotates, in the circle will create a contact between the two wires on the paper underneath. Once you have all your wires laid out, you should poke the pin all the way through both the circle and the paper behind it, so that the head of the pin is tightly pressed against the center of the circle.  Clip the pin shorter with the wire cutters, and using the needle nose pliers, bend the pin so that the head presses flush against the top of the circle, and the other end of the pin presses firmly into the back of the paper behind the circle.  Tape the back of the pin in place.

Tape the two coin cell batteries together, so they are in series.  Tape an exposed wire to the positive and negative sides of the newly formed battery pack. The positive wire will go to the positive leg of the LED. The negative end of the LED will go to one side of the switch you created in the previous paragraph. The other side of that switch will go to the wire attached to the negative side of the battery back.  Point the Led up, and tape everything in place.

Step 6: Where to Place the Circuit


Step 6

Choose a square to be the bottom of your cube. This is where the switch will be placed.  Measure .5 inches in from each edge of the square you have chosen.  Using an Xacto knife, cut out the center square you've created, so that your square looks like the picture.

Tape the smaller square with the battery pack, switch, and LED on it inside this empty square.

Step 7: Decorating the Cube

Step 7

Get out the felt, and cut decorative shapes to place on the face of each cube. Once you've decided where you want to place everything, you can glue the pieces of felt in place (you could also sew them in place if you want). 

Once all the felt is in place, draw a line approximately 1/8th of an inch in from the edge of each cube.  You can see my pencil marks in these pictures.  These lines will be where you stitch the edges of the cube together.

Step 8: Sewing the Cube Closed


Step 8

Using the embroidery thread and an embroidery needle, sew the box closed.  This image is what it looks like in progress.  You can see that two edges of the top face of the cube are sewn closed, and the other two are not.

Step 9: Turn It On!

Step 8

Turn the switch on, and you've got a really cute little night light!

Enjoy!

ohh I need one of those
Xacto officially owes me some money!<br>*grumble grumble*
This it great! The designs on the face is so cool! I made something similar to this on the next page, but this is just way too cool!<br>Good luck in the contest,<br>iJohnwickham
Nice!
