    What a cunning plan, not a logic chip in sight.

    Like it, bossman. :D

    I just have to have a go at making one of these for my machine but I have never made a PCB before.

    Any advice as to where to look for a tutorial ? and where to get the equipment/parts needed ?

    Excellent work Macroman, keep it up !!!

    Macroman,

    Thanks for the great guides.

    Even though I can't see using these particular mods in my current project, I read them again and again (my plans are always subject to change).

    I especially appreciated listing Hosfelt parts, for us folk on this side of the big pond.

    Mark.

    why not put the leds on a seprate bord that attches with ribon cable and have a green/red/blue/and/yello
    led boards

    The foil patterns are 4x size so they print sharply when reduced during printing. Actual size will produce poor prints.

    no print it as seen so the ink side touches the etch resist. It is shown as if you were looking through the top of the board.

    Wow... very, very impressive.
    Although I think that your cathode throbber circuit was the best off all, this one has the best written article.

    Anyway, I've got a great idea of how to make the effect even better... fiber... stick some 2mm fiber into the leds and then cram the fiber virticuly into a 3cm area (2mm per LED, 1mm between each of them). I think that the best color combo would be (from bottom to top) 3 white, 3 blue, 4 red; OR 4 white, 4 blue, 2 red (I'm too cheap for that one though)

    the problem is, I lost the name of that really cheap fiber supplier in the USA when I reformated, could someone please send me the link if they have it? FragSyndrome@hotmail.com

    hay mate soundlevel circuits are all over the net do a google i mad one for a mate if you can get access to one of those plasma balls(lamps) thay have one in and if its a bust one tha run off 12v so just use that (unless its that bit thats broke) ;)

    p.s. if its not brok be very carefull the ball is very thin i broke mine :cries:

    this will help me thinks loads of vu meaters
    http://www.discovercircuits.com/V/vu-meter.htm

    look for one with an audio jack in (headphone type connector) just add a female connector to the in put and run a male to male make from your sound card

    macro may help u more he may have more knowlage of these types of cricuit or even mail the onwer of that website

    Woohoo! It's about time. but no fading trail effect?

    question though. how many volts does the circuit supply on each LED? What if I was to use a 3.5v LED on there. do I need to adjust any resistor values or something like that?

    No worries about the voltage. But it does only sink 10 mA of current for each output, so as long as your LED will light up with a 10 mA drive current, you're ok. Just don't think you can parallel several LEDs on the outputs.

    I did originaly design it with the fading trail effect but considered the increased component count and complexity didn't warrant it for a simple project
