The Time Fountain (Also Know As Magic Fountain)
Intro: The Time Fountain (Also Know As Magic Fountain)
Update 05 June 2011: Here https://www.instructables.com/id/Magic-Fountain-Ultimate-Version/ a new and different version.
I was inspired by some others projects on internet (like this, for example: http://www.youtube.com/watch?v=ZRlNOyxWWf8& )
This "Time Fountain" works by the principle of the Stroboscope: http://en.wikipedia.org/wiki/Stroboscope
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 potentiometer.
The transistor (2N1711) can handle a maximum current of 500 mA.
I used 18 LEDs UV.
My Time Fountain video :
http://www.vimeo.com/23475559
Is very important to obtain a regular drip rate, for this i've used an infusion medical kit like this: http://servizimedia.altervista.org/fontana/img/Contagocce.jpg
The water is pumped upward, through a tiny pipe, and falls again inside the jar, cyclically.
With the strobe light (with a potentiometer we can set the frequency of lamps) i can set the effect on the drops, as you can see in the video. The drops are constant, i just change the LEDs frequency.
With strobe light we get the illusion of freezing the drops of water in midair, slowed or reversed!

Very Nice illusion!

18 LEDs: 5,20 Euro
Jar: 4,50 Euro
Strobe circuit: 10 Euro (assembled by myself)
Medical infusion kit: 1 Euro
Pipes: few Euro cents (about 0,60)
Water pump: 10 Euro
Black paperboard: a few Euro cents :-)
Fluorescent ink: i've just used 3 highlighter (one highlighter cost about 1,50 euro): 4,50 Euro
But for this part is more convenient to buy fluorescent ink in some DIY store..
For this project: https://www.instructables.com/id/Magic-Fountain-Ultimate-Version/ i've used 250 ml of fluorescent ink just for 3.20 Euro
So, the total cost for me is: 36,30 Euro (53 Dollars)
