Instructions

Plan Your Circuit

Our circuit contains an RGB LEDboard, a batteryboard, and a lobster clasp. The clasp is made of conductive metal, meaning electricity can flow through it. In the circuit, the clasp acts as a switch to turn the light off and on.

Connect the clasp to one of the holes marked “R”, “G” or “B” to turn on the LED. Switching the clasp to different holes with change the color of the LED.

R = Red
G = Green
B = Blue

 

Measure Your Wrist (Bracelet Only)

Start by determining how big your bracelet will be. Measure your wrist using a soft tape measure or using the provided cord and a ruler.

To use the cord, wrap the provided cord around your wrist snugly, like a bracelet. Mark the spot of the cord where it begins to overlap by holding the spot between your finger and thumb. Lay the string out flat against a ruler to measure the length.

Once you know your wrist size, add ½ - 1 inch to this size depending on how tight or loose you’d like it to fit. Our bead board will help you design bracelets approximately this size

Small: 6.5 inches
Medium: 7 inches
Large: 8 inches

* Small fits most kids 12 and under.

Design Your Bracelet or Necklace

Using your bead board as a guide, place beads in the grooves associated with your chosen size. For example, if you chose to make a small bracelet, fill just the two grooves labeled “S”. For a necklace, fill both long grooves. This will use all of the beads in your BeadKraft bead pack.

You can place your RGB LEDboard and batteryboard on your bead board while you design.

 

Prep Your Cord

Cut equal-sized pieces of cord and yarn. For the bracelet cut 12 inches of each, and for the necklace cut 20 inches of each.

Twist the conductive yarn and cord together so that they are wrapped tightly around each other. The wax on the cord should keep the conductive yarn in place. If they start to come apart, just twist them together more. You may also add a drop of glue to the end.

 

Fold the twisted cord in half and cut the cord so you end up with two pieces that are the same length.

 

Bead Positive “+” Side of Batteryboard

Take one of your twisted cord pieces and tie a double knot to the batteryboard through one of the holes marked with “+”.

 

Slide your beads onto this cord. Make sure you are sliding the beads over both the conductive yarn and the waxed cord. If they start to separate, hold both tips together and twist them together again.

 

Secure the beads by sliding all the beads towards the batteryboard, then tie a single knot on the other end of the beads. Add the clasp to this end by tying a square knot around the ring.

 

Bead Negative “-” Side of Batteryboard

Take the second piece of twisted cord and tie one end of it to the batteryboard through one of the holes marked with “-”. We recommend using the hole located diagonally from where you tied the other cord, but either hole will work.

 

Slide your beads onto this cord. Secure the beads with a single knot.

 

Then tie the negative hole on the RGB LEDboard to the end using a square knot.

 

Test Your Circuit

Now you can add your battery.

Attach your clasp to each of the holes marked with “R” (Red), “G” (Green), and “B” (Blue).  The LED should light up with the corresponding colors. Some flickering may occur due to the movement of the clasp.

If your LED does not light up:

  1. Check that your battery has enough charge to power the LED! If you have a voltmeter you can make sure the battery is above 2.5 volts.

  2. Check that your positive and negative connections are not swapped or touching.

  3. Check that your cord is tight around all the conductive holes.

You may need to re-tie your connections or re-make your circuit.  When you are confident that your circuit works, trim the excess cord around your knots.
