A 3D slide allows you to take to photos parralle to each other so you can combine them together to produce a great 3D image.
It will not include instructions on how to make the 3D photos themselves. There are other places on the web that show how once you have taken the 2 photos. I use a free program called Paint Dot Net http://www.getpaint.net/ to make mine.
Here is a tutorial that shows you how to use Photoshop to do the same thing. http://www.opentutorial.com/Make_3d_images
Here is one for Paint dot net http://docs.google.com/Doc?id=dsgjq79_473fn2g73dc
The parts for the slide should cost less than $5.00 and can be found at Home Depot or Lowes.
You will also need a tripod and digital camera (the camera must have a tripod fitting on bottom.
Tools you will need:
Here are the parts you will need:
(1) A 2x2 piece of wood. at least 8 in or so
(2) A 5/16" drill bit and 1" in paddle drill bit.
(3) 1ea 1/4"- 20x5/16 'Tee' nut coarsehttp://www.mcfeelys.com/product/SSN-2520/14-20-Stainless-Steel-Tee-Nuts
(4) 1ea 1/4 bolt and washer
(5) RTR Strong Tie. I bought mine at Home Depot for about $1.25. The are in the lumber section and are normally used to hold to pieces of wood together. http://www.strongtie.com/products/connectors/rtc-fwh.asp
Step 1: Cutting and Drilling
Mark a spot in the exact center of one side. This will be your top.
Drill all the way through at the center with a 3/16 drill bit.
Drill almost all with way through with a 1" paddle bit stopping at 1/4" from going all the way through.
Use drill to expand hole on RTR Strong Tie so it will be big enough to accommodate 1/4" bolt for camera.
Step 2: Putting pieces together.
Push all the way down then take a hammer a screwdriver and lightly tap the Tee nut into place.
At this point you can now attach to your tripod.
