This will show you how to take a scanner lens, and make it into a kaleidoscope. I chose not to seal the edges with tape, or glue to let light in. This way, it has a nice streak effect.
Step 1: Open It Up
Below the light, you will find three mirrors, CAREFULLY remove the light.
Now--be very cautions, the bulb in the scanner unit contains mercury vapors, and has the durability of a piece of uncooked spaghetti. Mercury vapors are invisible in most conditions.
Unscrew the brackets holding in the mirrors in the bottom of the unit.
Step 2: Assembly(A)
Now you should have three narrow long mirrors
There are two thicker ones, and 1 thinner one
Align the mirrors as shown:
(or however you like, if you think you can find a better arrangement)
Step 3: Assembly(B)
I held the mirrors in place with masking tape to let just a little light in to add a streak effect.
Your more than welcome to hold it together any way you want.
In these pictures I blocked the end, this is just ambient light coming in the sides where I didn't tape.
