Touch Screen Puppet
Give your puppet secret powers!
What You'll Need
Felt, 1 LEDboards, 1 batteryboard, 1 coin-cell battery, Conductive thread, & Thread
Step 1: Prep
Cut felt into the shapes of the puppet using our provided pattern. Make sure you cut two body pieces for the front and back. You can also come up with your own design to make your own unique puppet.
Glue all the accessory pieces to the front piece of your puppet.
Step 2: Conductive Feet
Take the conductive tape and place it at the bottom of the puppet where the feet are. Make sure you put a few strips together to make a wide piece so that it will be easy to sew on.
Step 3: Plan your Circuit
We are sewing the LED on the front and the batteryboard on the back. Layout the LEDboard where you would like it to be on the puppet. Make sure that the positive (+) and negative (-) holes will be aligned to the batteryboard when you sew the LEDboard on.
Step 4: Negative Connection
Thread your needle with conductive thread. We recommend doubling the thread for a stronger electric connection.
Attach the LEDboard by holding it in place on the fabric and looping around the hole 3 - 5 times.
Start by sewing through the negative hole on the LEDboard and sew it together with the battery holder’s negative hole.
Step 5: Positive Connection
Stitch down from the positive hole of the LEDboard to the foot on the left. Make sure you sew on the conductive tape. On the back side, sew from the positive hole of the battery board to the opposite foot. The positive stitches from the LEDboard and battery board should not be on the same foot.
Step 6: Test Your Circuit
At this point you can insert your battery into the battery holder. Make sure the “+” faces up to match the “+” on the battery holder. Your LED should light up!
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 LED 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 7: Attach the Back of the Puppet
To attach the back piece of the puppet on, sew a running stitch along the edge of the puppet. Make sure not to sew the top of the puppet so that you can put the battery in or take it out when you need to.
