You might be thinking this is a vibrant burning fire. It is, but, it’s not the real fire. Setting fire inside might be dangerous.
The first time I saw this, I was so amazed by it. Then I come closer to look at it; it still feels real, I then put my hand on the top it and try to feel a sense of warm, then I find it’s just mist, which is lighted by red lights from the bottom.
This fire is so real; you can never tell the difference from the real one if you watch it from a distance. I think the key is that the producer inside can generate the mist in the fire shape, I still don’t know how this works.
I think about the feeling that people get when seeing this, I feel much warmer. Most of the complaints from a swimming pool is always that why the water is so cold? But when people see a fire, they will have a warm feeling in the body.
Here is the video:
Interruptible LED Fade
Influenced by this amazing fire, I decided to use LED to simulate the nature of the light, combing with a natural style design.
I want to make something like a real fire, which is a bonfire.
First, I went through the primary circuit. I used the Arduino UNO,LED,Potentiometer.
I use the Potentiometer to control the frequency of the blinking. Also, I use the sine wave to smooth the blick.
See the codes here.
#define LED_PIN 10 // PWM PIN
//#define PERIOD 1000 // THE LESS THIS VALUE, THE FASTER LED WILL BLINK
//#define W 2*PI/PERIOD //SIN = AMPLITUDE *#define AMPLITUDE 127// Used to generate time for the cos wave
unsigned long timer = 0;int readValue = 0;void setup() {Serial.begin(9600);}void loop() {
readValue = analogRead(A0);
int period = map(readValue, 0, 1024, 100, 2000);
float W = 2 * PI / period;
// Serial.println(W);timer = millis();
int ledValue = 128 + AMPLITUDE * (cos(W * timer));
analogWrite(LED_PIN, checkValue(ledValue));
Serial.println(checkValue(ledValue));
}int checkValue(int val) {
if (val > 255)
val = 255;
else if (val < 0)
val = 0;
return val;
}
Then is the fabrication part. I try to find a natural piece of wood which has real wooden texture and feelings, I walk around the school and Washington Square Park, but I can not see a part which has the right size, and I know I can not cut a piece from the tree. So just image I have a row piece of beautiful wood like this
So I just cut a piece of Polly wood to make the light’s body.
Then I gather some branches and break them into small pieces. Then I glue them together to the top of the LED.
When the LED is on, it looks like this.
