Step 1: Materials
For the ninja:
Black material (I used felt)
Flesh colored material
Needle and thread
Glue (hot glue probably works best)
Some sort of fiber fill
Paper (to make the pattern for the ninja) or you can print the jpg or PDF that are on this step.The PDF is a bit bigger, and on top of our tree it's a pretty good size.
For the light-up part:
Some kind of switch or battery holder with a switch
A soldering iron
Perhaps some extra wire.
Step 2: Creating Radnor
Anyway, draw a ninja on a piece of paper. Or you can print out the PDF I have on the previous step.
So once you've drawn the pattern, cut it out and pin it to a piece of black material. I bet you know where I'm going with this, don't you? Yes, you probably do.
Cut out two of your ninja shapes.
Step 3: ...
Then on the other piece of your ninja sew on the flesh colored piece of material wherever you want his eyes to be, since they don't completely cover ALL of their face. Or at least Radnor doesn't.
Now take some kind of sharp object (Scissors, pen, xacto knife, axe, etc.) and stab two holes where you want his eyes to be. I never said this wouldn't be violent. Make sure the LEDs can fit through the holes.
Step 4: Putting Together Radnor
Step 5: Radnors New Brain
Solder (or tape or whatever) your two LEDs together with the positive lead touching the negative one. You might have to put some wire between them, depending on how far away the eyes will be.
Then solder the correct leads of the LEDs to the battery holder. Stick some batteries in it and see how it works! After I soldered it I put tape on all the places I soldered, because it was the first time I had ever soldered ANYTHING so I wasn't too confident in how well it would hold :P
Below is an overly simple and terribly drawn diagram for you to look at if you feel like it. If you don't have a battery holder with a switch, you can just put a switch in there connecting to the battery holder and then complete the circuit normally.
Step 6: Now for the Dirty Work.
Step 7: Radnor Is Almost Alive
Sew up the gash in the back of your ninjas head and stick the batteries in the pocket on his back. The top of the tree goes in the other half of the pocket on his back. If the batteries in the pocket on his back make the top of the tree bend you can just connect the batteries to the tree behind him.
Give him some accessories like a cape. Even though NINJAS DON'T WEAR CAPES! Or you could make him a "scarf thing". Or a cool little mask. But he kinda already has a cool little mask. But really, that's no big deal.
