Learn how to light up a mask!
What You'll Need
Felt, 2 LEDboards, 1 batteryboard, 1 coin-cell battery, Conductive thread, Elastic Band, & Thread (optional)
Sewing Needle, Scissors, & Glue
Step 1: Prep
Cut felt into shape of mask using our provided pattern. This mask has two layers of fabric. We made the back layer slightly larger than the front.
You can also come up with your own design, just make sure your eye-holes line up with your eyes.
Step 2: Plan your Circuit
We are sewing the LEDs in parallel, which means we will connect all the positives (power) on one side, and all the negatives (ground) on the other.
Lay out the LEDboards where you’d like them to be placed on the mask.
Make sure both LEDboards are in the same orientation, so the positive(+) holes are aligned and negative(-) holes are aligned. You can mark the fabric with a marker or chalk where you will sew.
On the back of the same piece of fabric, place your batteryboard. In this case, the batteryboard is about the same width of the LEDboard. Again, make sure you are aligning the "+" holes and all the "-" holes.
Step 3: Attach the LEDs
Thread your needle with conductive thread. We recommend doubling the thread for a stronger electric connection.
Attach the first LEDboard by holding it in place on the fabric and looping around the hole 3 - 5 times. We started with the negative holes, but the order doesn’t matter.
Use a running stitch to connect the negative holes. Sew around the second hole 3 - 5 times, secure with a knot, and trim the extra thread.
Repeat this process to connect the positive holes.
Do not connect the positive to the negative, and make sure the positive and negative connections do not touch at any point.
Step 4: Attach the Battery Holder
Using conductive thread again, attach the batteryboard (with no battery) to the back of the mask. Make sure the "+" and "-" holes on the batteryboard are aligned with the ones on the LEDboards.
Optional: To make the components extra secure, you can sew the extra the sew-holes to the fabric with non-conductive thread.
Step 5: Test your Circuit
You can insert your battery into the battery holder. Make sure the “+” faces up to match the battery holder.
If your LEDs flicker or do not light up: Check that your battery has enough charge to power the LED lights! If you have a voltmeter you can make sure the battery is above 2.5 volts. Check that your positive and negative connections do not cross or touch. Check that your thread is tight around all the conductive holes.You may need to take out and re-sew your connections.
If your LEDs do light up, you can add extra security to your circuit by adding a dab of glue to each knot. This will prevent fraying and loose threads, which can cause your circuit to stop working.
Step 6: Attach the Back of the Mask
Using small beads of glue, attach the second piece of fabric to the back of the mask. Make sure you can still access the batteryboard to eventually remove or change out the battery.
Step 7: Make it Wearable
Cut a small hole on each side of the facemask.
