Step 1: Materials
Step 2: Program LED Strip
Step 3: Program & Calibrate Wind Sensor
Experiment with blowing on the sensor and find the threshold that must be reached to get from inhale to exhale and exhale to inhale. Here's a good tutorial and sketch for getting started with the wind sensor.
Now use the wind sensor as an input and the LED strip as an output. Program the LED to change colors with inhales and exhales. The wind sensor is really sensitive so you'll have to observe the serial monitor as you inhale and exhale to figure out thresholds. Also, the threshold can change depending on location and weather so you might need to keep recalibrating. Here's the code we wrote.
Step 4: Make the Lamp
- Make or download an illustrator file of a mandala. Or use our file (attached here!)
- Set up the file for the laser cutter and print.
- Laser cut a circle of the same size for the back
- Cut strips of the bending ply to wrap around the edges
Step 5: Assemble the Lamp
- Cover the holes with translucent paper to diffuse the light
- Carefully use wood glue to attach the sides to the bottom of the circle. This is the trickiest part. We used a nail gun to attach anchor points around the bottom circle
- Spray paint the wood any colors you want
- Hot glue the LEDs around the side of the lamp. Drill a hold to stick the wires through the back
