  1. Hi all!

    I am new to this group and i am right now findin difficulties in
    making a digital clock for my college project. Can anyone help me out
    in this regard as my knowledge of electronics is still very basic as
    I am in second year only. please anyone help me out. any stuff..
    pdf.links etc are invited....
    my email id is ......
  2. Look around this site

    This is neat

  7. Was thinking on how many fuel injectors it would take.
    I assume that's the technology they use

    "All you gotta do" is create a stable time base - from an oscillator
    or the power line, count it down to the appropriate output (modulus
    60) then send it to some TTL or CMOS latch decoder output for your
    flavor of display.

    If you can't figure it out, perhaps you could major it pottery or
    basket weaving? Google isn't your friend Google Groups really hates
    your lazy ass.

    According to the clip, it's "Approximately 3,000,... similar to an inkjet

    Don't you ever check links?

  10. the download was too slow, and i gave up after 30 seconds, fun while
    it lasted though

  11. Looks more like the water is simply falling and not being squirted. At
    least not with any significant pressure. I suspect they have a trough with
    water in it and 3000 valves that open/close allowing water to simply fall
    thru nozzles.

    It's neat, but the laminar flow tricks that I've seen are spectacular.
    Using that technology and shooting the water up and over backwards (in an
    arc) could make for some pretty neat displays since the water looks like

    Is the project itself a digital clock, or a digital clock a part of a
    larger progect project? Is it to be a unique way to display time. Does
    it have to be practical, or can it be "out of this world, anything
    Can a micro be involved? if yes, small, big, or a PC? Can there be
    moving/ motorised parts?

    If it were me, I'd do a bedside type clock with an LCD, a lesser micro,
    a 2X20 backlit LCD, and some rotary knobs to set the thing, plus a WWVB
    receiver to set the time. Maybe that's beyond your class level.
