Step 1: Lets Get Fetching!
>A Shoe Box
>A Sheet of Mirror (Preferably PVC or Acrylic)
>A Projector Lens (Slide Projector ones Work Well)
And the Following tools:
>A Stanley Knife
>A Straight Edge
>A Ruler in MM
>A Marker Pen
>A Basic Scale Drawing Ability.
NB: ALL MEASURING TASKS ON THIS PROJECT MUST BE PERFORMED USING A RULER FOR THIS TO WORK.
Step 2: Cut the Lens Barrel Hole
E.G. Top Left to Bottom Right and Bottom Left to Top Right.
Where the lines Meet give you your Center. Measure the Radius of the inside of your Barrel and Cut your hole from the Center accordingly.
Step 3: Marking the Mirror Angle
Next Draw A 12x12 cm Square
If you are on the left of your box draw from The Top right to the bottom left.
Then from the right draw from the Top Left to the bottom right.
On the inside you will need to draw the lines for positioning the mirror.
Step 4: Cut the Screen Hole
Depth = Line Distance from Top.
2. Draw a Line 4cm from the top of the box.
3. Draw a line 8cm from the top of your line drawn in step 1 as if to meet the line drawn in step 2.
4. Draw lines going from the left to right sides at the level of the lines Drawn in steps 2 and 3.
5. Work out the area of your screen on your device;
Half your X and Y Axis values and mark a point for each and join the lines. Work from your center line and mark measuring half of each value on each side.
6. Then Stanley the Hole out neatly tidying the edges.
Step 5: Finalising
Get your Straight edge and put it along the line and score a couple of times with the Stanley, Continue this as Necessary then Snap the mirror out along the Lines.
Finally Put the Mirror into the Box with the edges along your pre-marked lines. When you are Happy with the Positioning simply glue gun the mirror in Place.
Step 6: Showtime!
The images Below do Not do the Actual Projection much Justice, you would have to see for yourself the actual quality and brightness.
