Magic FountainAll > Magic Fountain by davediamond
The "Magic Fountain" is based on the principle of the Stroboscope. http://en.wikipedia.org/wiki/Stroboscope
With strobe light we get the illusion of freezing the drops of water in midair, slowed or reversed!
I made this fountain using a little submersible water pump inside a decorated jar, fluorescent water (with highlighter's ink) and UV LEDs, to obtain strobe light, using a simple strobe circuit based on a pair of ne555 (with a low duty cycle).
With this circuit we obtain a strobe light with duty cycle and frequency both adjustable via two potentiometers.
The transistor (2N1711) can handle a maximum current of 500 mA.
I used 18 LEDs UV.
