    Hi Russel, thanks for the post... Just check the attach picture, yes, this is infancy stage of graphical fountain binary code generator. It takes Black and White WMF file, convert it into binary files. The Black appears '1' and the white appears '0'. The attached pictures shows that their are 50 solenoid valves. so 50bits for on/off of these solenoid valves. You can customize the generated binary code for upto 100 solenoid valves, however this can be increase more... The more solenoid valves, the better the resolution.

    Now check each rows. we will send each row to the micro-controller in the form of bits through 74HC595 SIPO bit shifter. HC595 gets 3-lines in from the micro-controller and output 8 lines. these registers when connected in series gives tremendous output with only 3-inputs from micro-controller.

    Now in microseconds one complete row of solenoid will be operated. The delay between the next line may be adjustable....

    Consider a Chess board falling from fountain.... just removed the 0 bits... Just think the '1' is falling water pattern.

    Nice work, I like how you made your own program to generate the binary pattern

    Thanks Russell...the binary conversion of a picture as per number of solenoid valve is completed, meanwhile I am currently adding serial port communication capabilities in the software...

    At hardware side i made a simulator of 16Leds using 74HC595 shift register... Tested the hardware last night and its working perfect..will soon post the pictures for updation.

    Add the capability to use colored water from tanks for short RGB color "surprises" during the waterfall show. CarveOne

    There's a waterfall in a building in Japan that does something like this, the vid is on YouTube but I ca['t find it yet...

    Hi carveOne,
    The Scheme is very simple... All the solenoid valves will be connected to one overhead tank. So whatever color you fill in the tank the same will be displayed in water fall.. But, we can add some colored lighting just below the Solenoid valves..For this we will use Plain water with no color, and we will get the reflection of different lights colours in the drops.

    At the start of this thread i have added some Youtube videos.

    That will be less complex, less costly, and better than just plain water.

    My idea is to add the capability in the software to allow someone (with lots of money) to do this so that the "water pixels" can be selectively colored as in the old 16 bit RGB computer monitors. It would be like seeing low resolution color images in the waterfall. The colors would stay together all the way down. The Japanese aren't doing that yet are they?

    Wow.. Thats a nice idea CarveOne..This idea is plausible and doable...and i just imagine the beauty of that fountain.. But it will waste a lot of water as no recycling will be done.. and need a drain pipe too... (Environmental issues)

    Japanese are very clever people...
    updates:
    Last night, i have improved the software.. The binary code was further converted into Hexadecimal and Decimal...
    Today i will try to make a communication between hardware and Software...

    I was just trying to offer an idea for something "extra". I know that it will have some extra effort in software, and other issues to overcome.

    It seemed to be something that would eventually happen anyway, and I was hoping that you would be the one to do it first. At least in the software side of it and let someone else figure out the rest. There's always an artist looking for a new way to express himself or herself. They can usually find the financial backing to build it.

    Good luck with your new waterfall venture.

    Hi carveOne,
    I can do that in the software but only for you...If you agree to make one and install it in your beautiful workshop

    Look at the video of the working simulator and the following data:

    0000000000000000
    0000001111000000
    0000111111111000
    0000111111110000
    0000001111100000
    0000001111100000
    0000011111110000
    0011111111111110


    Just see how the leds on/off as per each row of data...
