Pretty cool, huh? This kaleidoscope gives time-lapse photography unlimited potential. Here's the steps you need to make one. Enjoy.
Step 1: Materials and Tools
- DSLR. I used a Nikon D90.
- Intervalometer. Unfortunately/fortunately, Nikon doesn't make one for the D90, so I had to buy a third party one. It actually works surprisingly well, though, and saved me a bundle.
- Long mirror
- Duct tape
- Electrical tape
- Wood glue
- PVC pipe
- Motor. I used one that had 7 RPM. It worked very well; you want the motor to turn very slowly.
- Battery snap
- 9 volt battery
- Scrap wood
- Hose clamp
- Big wooden dowel
- Nails, Screws, Bolts, Nuts, Washers
- Tripod clip/mount
- Glass cutting kit
- Washable marker
- Chop saw or hack saw to cut PVC pipe
- Utility knife
- Soldering iron and solder
- Drill and different sized drill bits
- Square and Ruler
Step 2: Building the Kaleidoscope
Measure the lens if you want to, but you can just eyeball it. This will give you a rough idea of how big to make your kaleidscope (and I would recommend erring on making it bigger).
Alright, now we can start. First, get a long piece of mirror. Then, using a glass cutting kit, carefully cut out a piece of mirror. The pieces I cut out were 6 inches long, but looking back I would have made them smaller (about 5 inches). I only know the basics of glass cutting, but you just scrape the cutter along the mirror, and then tap it with the other end of the cutter. It should just break right off. Then, trace the outline of the piece with a marker twice. Cut out those two pieces. You should now have three identical pieces of mirror. Tape them together in a triangular prism shape with a strand of duct tape. You need to allow some space between the pieces so that they can fold together, but not so much that they are loose. There! Now you have a basic kaleidoscope. Test it out with your camera.
Step 3: Housing for the Kaleidoscope
Here's a basic outline of how we want the kaleidoscope and housing to be, from one end of the pipe to the other. On one end, we want about half an inch of just PVC pipe, followed by the kaleidoscope. This gives it some protection. Then we want about 3-4 inches of just PVC pipe, so that your camera lens can slide in.
So, you may need to cut the PVC pipe if you have extra. I used a chop saw, but you could just use a hack saw.
Alright, to recap, you should have a kaleidoscope that can fit snugly in a piece of PVC pipe that you cut down to size.
Step 4: Motor
Quick test, grab a 9 volt battery, snap it into the snap, and see if the motor rotates.
Step 5: Woodwork
I used a lot of scrap wood, because I was just building it one thing at a time, and realized that I might make mistakes and waste nice wood. Bottom line: scrap wood works fine.
First things first, we need a base. Mine was 18 inches by 10 inches. It was pretty heavy, which is what you want.
Next, we need to work with the motor. First, get a piece of scrap wood about 5 1/2 inches long by 1 inch wide. Cut a small groove on the bottom of it. Then, take a hose clamp and fasten the motor to the piece of wood.
Now, take a big wooden dowel (the diameter I used was 1 3/4 inches), and cut it into two identical pieces that are about an inch longer than the kaleidoscope pipe; mine were 10 inches long. These next steps are very important. Make sure that each time you drill, it is nearly perfectly centered. Now, find a drill bit that is the same size as the motor shaft, and drill it into one end of one dowel. Then, find three long-ish nails, and a drill bit that is the same size. With the remainding three ends of both dowels, drill a couple inches deep perfectly centered and straight with the nail-sized bit. This is a good time to wrap the dowels and kaleidoscope pipe in electrical tape. It will increase friction immensely, and therefore help the whole thing spin.
Next, take two other scraps of wood. One piece you want to be about the length of the width of the base (so for me, 10 inches), and about 3 1/2 inches tall. With this piece and a jigsaw, cut out a half circle about 4 inches long from the center of it, and about 2 3/4 inches deep. Then, wood glue and nail this piece to one end of the base. The other piece of scrap wood should be cut down to a 2 1/2 tall by 3 inch wide rectangle (note: I made mine too long [4 inches], and that got into the way of the lens. I then had to cut out a quarter of circle out of the piece, once it was already nailed down. It was very tricky, don't make this mistake).
Now, you should have.... A base with a piece of wood (the one with the half circle cut out) attached to the end of it. Two dowels, one has the same sized hole on each end. The other dowel has the same hole as the other dowel on one end, but on the other end it has a differently sized hole drilled in it, sized to fit the motor shaft. The motor is attached to a block of wood with a hose clamp. Finally, a small rectanglular piece of wood 2 1/2 inches by 3 inches.
Good? Alright, next step. Remember the three nails? Take two of them. Nail them into opposite side of the board with the half circle (you may want to drill the holes where you want them first, and then hammer in the nails). Take the motor attached to the wood piece and fit it into the dowel. Then, fit the dowel into the nail, keeping it loose, and nail down the motor into the base (about two inches in, length wise). Then, take the other dowel (the one with the two identical holes), and fit one end onto the nail that is sticking out. Again, keep it loose. Now, you should have one nail left, of the three originally. You also should have the rectangular piece of wood left. Mark where the nail will meet the dowel, and then drill a hole, hammer in the nail, and then fit that into the dowel. Then, wood glue and/or nail that rectangular piece of wood onto the base.
Let's do another recap, shall we? You should have a base of wood, with two pieces of wood attached to it, and a motor. Between one piece of wood with a half circle cut out of it, and the motor and smaller piece of wood are two dowels. Both dowels are loosely suspended by two nails. The motor should be attached to a battery snap, so snap it onto a 9 volt battery and make sure the one dowel spins. Then, put the kaleidoscope pipe in between the two dowels. It should spin slowly.
