Scissors, Ruler or Soft Tape Measure, & Bead Board
Fold an origami boat or build one out of cardboard. You can refer to the image on the right for a design. Assemble your ghost ship. Make sure you create a pocket in the boat for your ghost LED.
You can also come up with your own design and lasercut the shapes, just make sure there is a spot for the ghost LED.
Plan your circuit
This circuit contains a LED, a battery and temperature sensor. Conductive tape will be used to create the connections.
In the circuit the temperature sensor reacts as a switch to turn the LED on and off. Connecting the circuit using the pad labeled ‘warm’ will trigger the light to turn on after you blow warm air on it.
Attach components to the jar side
Place the batteryboard outside of the glass jar on the bottom, use transparent tape for fixing it. Place temperature sensor on the side of the jar. Follow the circuit scheme and make sure that none of the connections will cross later.
Add conductive tape
Now use conductive tape to connect the batteryboard to the temperature sensor.
Use conductive tape to attach the circuit to the jar.
Complete the circuit loop
Continue by connecting the loose ends of the conductive tape to the fabric strips (yellow on the image). Using fabric strips gives conductive tape a stronger surface an the flexibility to move the ghost LED around.
Make sure conductive tape ends with a connection to the pads of the ghost LED.
Decorate your jar and test out your project
Place your ghost inside the boat and add some colorful paper to add water for the boat to sit on. Place the boat inside the jar.
Now test your project: the ghost LED will light up after blowing hot air on the temperature sensor.
