How to Build a Tiny Electronic Patch That Makes Your Phone Waterproof Using Stuff You Already Have Around the House

Making your phone waterproof can seem daunting, but with a few simple household items you likely already have, you can create a tiny electronic patch to keep your phone protected. This cheap and easy method will allow you to use your phone worry-free around water without spending money on a bulky waterproof case.

What You'll Need

• Clear packing tape - This provides the waterproof barrier and allows the touchscreen to still be used. Regular clear household tape can work in a pinch.
• A small piece of plastic sheet - A stiff plastic material like an old gift card, expired credit card, or cut piece from a plastic container works well. This gives the patch structure.
• Scissors - For cutting the plastic and tape to size.
• Rubbing alcohol - To clean the phone where the patch will adhere.

How to Make the Patch

Step 1: Cut the Plastic Base

Use scissors to cut your plastic sheet down to a size that will fully cover the charging port/earphone jack area of your phone. Leave some extra room on the edges for the tape border. Cutting a rectangle an inch or two wide usually works well.

Step 2: Clean the Phone

Use a cloth or cotton pad dampened with rubbing alcohol to clean the area where you'll apply the patch. This helps the adhesive stick firmly. Make sure to clean both the phone and the plastic base piece.

Step 3: Apply Tape

Place the plastic directly over the port area on the phone. Apply strips of clear packing tape over the plastic piece and phone surface until completely covered and firmly adhered. Press the tape down firmly as you apply it, smoothing out any air bubbles.

Step 4: Seal the Edges

Apply additional strips of tape extending at least 1/2 inch beyond the edges of the plastic, adhering them to the phone surface. This seals up and waterproofs the edges.

Step 5: Check Adhesion

Once assembled, firmly press and smooth the whole patch to maximize adhesion. Ensure the tape is stuck tightly with no lifts at the edges.

Using Your Waterproof Phone Patch

• Avoid submerging your phone in water, even with the patch. It's water resistant, not fully waterproof.
• The touchscreen and buttons will still work with the thin tape barrier.
• Whenever removing the patch, use new tape pieces when reapplying for best adhesion.
• Check edges frequently for any lifts or peeling tape. Smooth down as needed.
• Replace the patch completely if you see water intrusion under it.

With proper application and care, your DIY phone patch can protect against spills, splashes, rain, and other minor water exposure. Have fun using your phone with less worry about water damage! Let me know if you have any other questions about creating this effective yet inexpensive solution.
