Materials Needed to Build Your DIY Teleprompter

Shopping List for Your Homemade Teleprompter

  • Glass or Clear Acrylic: A 8x10" or 11x14" picture frame (remove the backing) or a sheet of clear acrylic. This will be your "beam splitter" that reflects the text.💡 Where to buy: Frame shops, craft stores, or hardware stores (acrylic)
  • Support Structure: A sturdy cardboard box (large shoebox or moving box) or a lightweight wood frame (plywood or MDF). Paint the inside matte black to prevent unwanted reflections.💡 Where to buy: Office supply stores, craft stores, or lumber yards
  • Display Device: A tablet (7-10 inches is ideal), smartphone, or portable monitor to display the script.💡 Use what you have! Old tablets work perfectly
  • Black Cloth or Cardboard: To create a "tunnel" between the camera lens and glass, blocking ambient light and ensuring the camera doesn't appear in the reflection.💡 Where to buy: Fabric stores or office supply stores
  • Camera: Any DSLR, mirrorless, webcam, or even your smartphone camera.
  • Tape/Hot Glue: To secure the pieces.💡 Hot glue is ideal for quick assembly and adjustments

💰 Total Estimated Cost: $10 to $30

Compare with professional teleprompters that cost $200 to $1,500+

⚠️

Beware of the Mirror Effect!

When using glass to reflect text, it will appear reversed. You'll need software that supports Mirror Mode. PromptNinja includes it for free so you can start recording right away.

📱 Using a Tablet or iPad?

Tablets are excellent for DIY teleprompters due to their screen size and portability. If you plan to use one, check out our specific guide on how to use a teleprompter on tablet for positioning tips and setup.

Step-by-Step: How to Build a Homemade Teleprompter

O que você vai precisar:

Ferramentas

  • Scissors or Box Cutter
  • Smartphone or Tablet (to display text)
  • Camera (to record)

Materiais

  • Cardboard Box or Wood
  • Glass or Clear Acrylic
  • Black Cloth
  • Tape or Hot Glue
1

Step 1: Prepare the Base Structure

Take your cardboard box and cut a front opening for the camera and a bottom opening for the tablet to sit at a 45-degree angle. If using wood, build a box in an inverted "L" shape. Tip: Paint the entire interior matte black to eliminate reflections that might appear in the video.
2

Step 2: Position the Glass/Acrylic

Attach the glass or acrylic at a 45-degree angle between the camera (which will be behind) and you (who will be in front). This angle is crucial so the text reflection is only visible to you, not the camera. Use hot glue or double-sided tape.
3

Step 3: Position the Tablet/Monitor

Place the tablet or monitor at the bottom of the structure, facing upward toward the glass. The text on the screen will reflect in the glass and appear in your line of sight, just below the camera lens. Set the tablet's screen brightness to maximum.
4

Step 4: Block Light with Black Cloth

Create a "tunnel" with black cloth around the camera and glass. This prevents external light from interfering with the reflection and ensures the camera doesn't appear reflected in the glass.
5

Step 5: Configure the Software (PromptNinja)

The most important step: the text on the tablet needs to be mirrored. 1. Go to promptninja.solutionkit.com.br on your tablet. 2. Paste your script. 3. Click the mirror icon (🪞). 4. Scan the QR code with your phone to use it as a remote control. Done!

Optimizing PromptNinja for Your DIY Setup

Recommended Settings

  • 🔆
    Screen Brightness:

    Set tablet brightness to maximum. Glass reflection reduces light intensity, so you need to compensate.

  • 📏
    Font Size:

    Test different sizes. For a 10" tablet, we recommend starting with 48-60px and adjusting based on your distance.

  • 🎨
    Contrast:

    Use white text on black background for maximum reflection contrast. Avoid light background colors.

  • ⚡
    Speed:

    Start slow (50-100 WPM) until you get used to the setup. Use the remote to adjust in real-time.

  • 🔋
    Power Saving Mode:

    Disable tablet's power-saving mode to prevent the screen from dimming during recording.

Common Problems and Solutions (Troubleshooting)

❌ Problem: Reflection is very weak or almost invisible

Solution:

  • Increase tablet brightness to maximum
  • Reduce room ambient lighting (reflection is more visible in the dark)
  • Make sure the glass is clean and spotless
  • Check that the glass angle is correct (45 degrees)

❌ Problem: Camera is recording the reflected text

Solution:

  • Adjust glass angle to exactly 45 degrees
  • Check that black cloth is blocking all light around the camera
  • Reduce tablet brightness (if reflection is still visible to you)

❌ Problem: Text is cut off or not fully visible

Solution:

  • Adjust distance between tablet and glass
  • Use a larger tablet or glass
  • Reduce font size in PromptNinja
  • Move slightly further from the structure

❌ Problem: Text is difficult to read (blurry)

Solution:

  • Clean the glass thoroughly (fingerprints cause distortion)
  • Use glass instead of acrylic (scratched acrylic distorts more)
  • Increase font size in PromptNinja
  • Use sans-serif fonts (Arial, Helvetica) which are more readable in reflections

❌ Problem: Remote control is not working

Solution:

  • Make sure tablet and phone are on the same Wi-Fi network
  • Reload the PromptNinja page on the tablet
  • Scan the QR code again
  • If needed, check our P2P remote control guide

FAQ: Frequently Asked Questions About Homemade Teleprompters

Why does the text look backwards on my DIY teleprompter?

This happens because of the physical reflection on the glass. To fix this, use PromptNinja and toggle 'Mirror Mode', which horizontally flips the text so it's readable in the reflection.

Do I need special glass or does regular glass work?

Regular picture frame glass works perfectly! Professional "beam splitter" glass (50/50) is better, but for a DIY homemade setup the difference is minimal and the cost is 10x higher. The important thing is that the glass is clean and scratch-free.

How much does it cost to build a homemade teleprompter?

Between $10 and $30 if you buy all materials from scratch (glass, box/wood, black cloth, glue). If you already have a tablet and camera, it can cost under $15. Compare with professional teleprompters that cost $200 to $1,500+.

How do I prevent the camera from recording the reflected text?

The secret lies in three factors: (1) correct glass angle (45 degrees), (2) black cloth blocking light around the camera, and (3) proper lighting. The camera, positioned behind the glass, captures the image in front of you, while the reflected text is only visible to those in front (you).

Can I use my phone instead of a tablet?

Yes, but tablets are much better due to their larger screen. If using a phone, choose one with a large screen (6.5"+) and position it closer to the glass. It will work, but the reflected text will be smaller and harder to read.

Does PromptNinja work offline on my DIY teleprompter?

Yes! After loading the page once, PromptNinja works offline thanks to PWA technology. The P2P remote also works via local Wi-Fi, without needing active internet.

Do I need to install an app on the tablet?

No! PromptNinja works directly in the browser (Chrome, Safari, Edge, Firefox). Just access the website. You can install it as a PWA (Progressive Web App) if you want, but it's not required.

Does the PromptNinja remote work with any phone?

Yes. Any smartphone that can read a QR code and has a modern browser can be used as a remote control. No need to install anything on the phone — everything works in the browser via local P2P connection.

Can I use acrylic instead of glass?

Yes! Clear acrylic works well and is lighter and safer (doesn't break). The only disadvantage is it scratches easier, which can slightly distort the reflection. If using acrylic, protect it with a removable film.
