This homemade fountain uses three intersecting water jets to mix Red, Green, and Blue (RGB) LED Lights inside water clouds that change color, shape, and form in the most amazing ways. Instead of mixing uniformly, Light forms surprisingly complex color patterns within the turbulent water clouds. Some of these colorful clouds resemble deep-space Nebulas that Astronomers record with their powerful telescopes.
Follow the instructions in the video to observe individual Water Nebulas. Note how quickly they transform from one pattern to a totally different one just a short time later. The HD video camera (Canon VIXIA) that I used to film the close-up sequences is also influencing the results. I would need a very fast camera to see where the Red, Green, and Blue Lights go after they reach the intersection region of the three jets.
INTERNATIONAL YEAR OF LIGHT
The United Nations designated this year, 2015, as the official International Year of Light (IYL 2015). Since last January, all kinds of ceremonies and activities took place around the world to celebrate Light and Light-based Technologies. My “Nebula Fountain” project is in part motivated by these celebrations of Light. Visit this website to learn more about the programs of IYL 2015.
LED CIRCUIT COMPONENTS
1. Red Light-Emitting Diode:
Model = RL5-R5015; Size = 5 mm;
Light Wavelength = 631 nm; Output = 5000 mcd;
Output Spread Angle = 15 degrees
2. Green Light-Emitting Diode:
Model = RL5-G8020; Size = 5 mm;
Light Wavelength = 525 nm; Output = 8000 mcd;
Output Spread Angle = 20 degrees
3. Blue Light-Emitting Diode:
Model = RL5-B5515; Size = 5 mm;
Light Wavelength = 470 nm; Output = 5500 mcd;
Output Spread Angle = 15 degrees
4. Timer Model TLC555:
This component provides an output signal whose frequency can be adjusted to produce the desired modulation periods (14 – 15 seconds) for LED Light intensities.
5. Operational Amplifier Model LM741C:
This Op-Amp is used as an “Emitter-Follower” to isolate the Timer output from the Transistor driving circuit.
6. Transistor Model 2N3904:
This Transistor provides enough current to drive the LEDs.
7. Common Resistors:
R1 = 100 KOhms; R2 = 1 MOhms; R = 100 KOhms
8. Red LED Resistor: RL = 113.8 Ohms
(You may have noticed that the intensity of the Red Light does not go all the way down to zero. This might be due to a slightly off RL. Try RL = 116.3 Ohms instead.)
9. Green LED Resistor: RL = 73.8 Ohms
10. Blue LED Resistor: RL = 74.7 Ohms
C0 = 10 microF; C1 = 0.01 microF;
C = 100 microF (Blue electrolytic capacitor)
FUTURE DREAM PROJECT
If I could afford my dream house, I would build it with a large circular swimming pool in the backyard. By adapting the design of my Nebula Fountain to a much larger scale, I could install three perfectly Laminar Water jets around the perimeter of the pool for Red, Green, and Blue lighting. To achieve the net effect of a bright Water Nebula that appears to be freely suspended over the center of my circular pool, I would need to improve my fountain design in three important ways.
1. I would make the water in the three jets flow uniformly without turbulence. This is the regime of Laminar Flow which is difficult to realize in practice.
2. I would remove all microscopic impurities from the water in the three jets. The jets must guide most of the Light all the way from their LED sources to the Nebula Light Bulb where it exists the water.
3. I would install a special mechanical device for steering the jets with precision. This would allow me to align the three jets so that they intersect at one point on the axis of the pool at a prescribed distance above the water surface.
The above three improvements should create the illusion of a giant colorful Nebula Light Bulb which is freely suspended in mid-air over the center of the circular pool.
