For This Tutorial You Will Demand
- Shoe box (or like)
- Thick black paper or black matte paint
- Pencil
- Ruler
- Glue and brush
- Double-sided record (optional)
- Scissors or precision knife
- Magnifying glass
- Mirror.
Step ane: Choose the Right Mirror and Box for Your Bootleg Projector
To build this projector, we will identify a mirror and a magnifying lens in a box to make the low-cal rays coming from your telephone create a bigger projected prototype. The more than light reaches the magnifying glass, the brighter your last image would be. For that reason, you lot desire to accept a relatively narrow box to avoid calorie-free dispersion before reaching the glass.
You demand a long box so that you tin can adjust the distance between the projecting lens and your phone. With that in heed, you demand to use a box that your phone'southward screen will fit across. In my example, I took a box 16x31x12 cm.
The mirror should exist rectangular and plain and be at least the same size equally the phone you will utilise.
Step ii: Black Out the Within of Your Projector for Better Image Quality
Using a precision pocketknife or scissors, cut out one of the narrow sides of your outer box. Proceed it considering it is an essential piece of your projector.
Make sure to cut the lid of the box as well.
Light reflecting off from the walls of the box would cause noise and tin can result in lower paradigm quality. To avoid that, you should make the inner sides of the projector black. You tin can coat the inside of the projector by glueing black matte newspaper.
Utilise a castor to evenly spread the gum and then that the black newspaper is attached firmly to the box. If you prefer, you tin use double-sided tape instead of glue.
Some other pick is to paint the box. Proceed in mind that you will demand to let the paint dry and make certain to use a product that has a matte texture. You also need to glaze the inside of the box lid and the narrow box side you cut out previously.
Step iii: How to Install the Lens in Your DIY Smartphone Projector
Have your magnifying drinking glass and remove its handle. Trace the outline of the magnifying glass on the centre of the narrow side you've cutting out.
Utilise the precision knife to cut out the outline and then that the magnifying glass fits snugly in the opening you've made. Now you take your Lens side ready to be installed.
Stride 4: Making an Adjustable, Transmission Focus for Your Smartphone Projector
Having an adjustable focus means nosotros need to exist able to move the lens in relation to the phone. To accomplish that, you need to construct a second box that will fit inside the outer box. Take the measurements of the inside of the box. Create folds in 4 sheets of black paper so that they fit the edges of the box, use a ruler to create precise folds in the paper.
Once you have all four folds, brand 5mm deep cuts at one of the edges and fold the flaps yous've made.
Adhere the flaps to its next ones using glue.
This will brand the structure more rigid. And so gum the papers to each other to make an open up box. Finally, glue the lens side onto the flaps of the inner box.
The inner box should have a relatively tight fit inside the outer 1.
Step 5: Installing the Mirror in the Cardboard Smartphone Projector
The lens projects images from the phone by concentrating and refracting the calorie-free. This means that the prototype nosotros go on the wall is flipped upside downwards and left to right. Fixing the starting time is like shooting fish in a barrel. All you have to do is to deactivate the phone's screen auto-rotate option and identify the phone upside down.
To right the prototype left to right, you demand a mirror to get a mirror epitome the lens would invert.
Place the mirror at a 45⁰ angle on against the side that is opposite of the lens. Cheque that when you lot wait at the mirror from upwardly, you can see the projecting lens.
Step vi: Cut Out a Window for Your Smartphone
Mensurate the width and length of your phone'due south screen. Draw a rectangle with your phone screen size on the chapeau of the projector, right higher up the mirror.
Cut out the rectangle with a precision knife. Don't worry if yous can cut the rectangle a bit also big, simply exist careful not to exceed the size of the phone itself.
Fit the magnifying glass into the pigsty y'all cut out in step 3. And with that, y'all are done! You've fabricated your very own smartphone projector. If you want, you can decorate it using paints, colorful papers or any other materials yous accept around.
How to Adjust Your Projector'due south Focus for an Optimal Paradigm
To gear up your projector, place it in forepart of a white wall or a screen. Turn your phone's brightness to maximum and place it facing down on elevation of the cut-out opening you lot've made. I recommend you to plow off the auto-rotate and set the screen sleep time to "Never". Next, turn off all the lights in the room, the projector should exist the only lite source.
Start sliding the lens slowly away from the mirror while looking at the image on the wall. Stop moving the lens when you get a sharp paradigm. Y'all might demand to change the altitude between the wall and the projector if the epitome is not abrupt enough.
Building Your Projector Without a Mirror
If you don't accept a mirror available, you lot tin yet make a projector. Place your phone with the image upside downwards directly in front of the lens. To keep the telephone secured in its position, I recommend attaching it with a Velcro. This will also brand taking the phone out easier.
Without the mirror, your smart telephone projector won´t correct the inversion of the image. For that reason, I recommend you avoid anything with writing.
