    Sorry for my bad english

    @redvodka39
    every output of the LM3916 goes to one blue and one white led at the same time, but the other leg of all ten white leds is wired to the switch, same for blue.. so, when the switch is in position 1, minus connection for ten white leds is connected (blues are off), and in position 2 whites common minus is disconnected and blue is connected…
    another switch is on-off, and third switch is for the third row of white leds, which light at the same time, like a lamp…

    Hi mixcev , i make your circuit and it’s work , but i have a litlle problem!!
    i have to setting the music so verry loud before the leds lighting up ??
    The first four ok , but the other leds are lightly ?
    Can you help me to fix that ,

    Hi! Can I put electrolytic capacitors instead the ceramic ones?
    Thank’s!

    mixcev on January 30th, 2012 at 6:47 am

    @redvodka39
    you can lower the resistor on the mic to 5KOhm, two 20K resistors can be lowered, but be carefull!!! maybe lower capacitor instead of 10uF….
    after all, you can raise the power supply voltage on the LM386, so the higher voltage goes to 3916, or lower the supply on 3916, so its more sensitive for voltage from 386…
    these are suggestions, they might not work, be carefull, dont blame me if something goes puff :)

    this is an electret microphone

    mixcev on January 30th, 2012 at 6:47 am

    @MetalHippy88
    now you can only rip it from youtube video (google “download mp3 from youtube”)…
    i uploaded a .wav file so its a decent quality…

    MetalHippy88 on January 30th, 2012 at 6:47 am

    Hey You´re a God :P Very Nice Tower ^^

    Hope U Can Help Me thx Before ;)

    @mixcev
    or maybe u just can make a box of desired thickness and fill it with water then seal it (using flourescent dye and balck light leds comes to my mind)

    xXSpeedXxXHunXx on January 30th, 2012 at 6:47 am

    @mixcev Thx man :D D

    mixcev on January 30th, 2012 at 6:47 am

    @xXSpeedXxXHunXx
    10 days +10 leds +30cm =50euros :)

    xXSpeedXxXHunXx on January 30th, 2012 at 6:47 am

    how much this?

    efivip93 on January 30th, 2012 at 6:47 am

    i just love this song

    NICE i need to do a project 4 school (making a led vu meter) but i can only use 5 V and my micro controller only has 18 pins ind i can use 9 of them 4 leds you god a god ideah?

    kctess5 on January 30th, 2012 at 6:47 am

    @Flogo85 add a resistor of potentiometer

    MrAnafiga on January 30th, 2012 at 6:47 am

    good job !!

    i built something similar with LED-lighted letters from the sign of an old shop.
    check my videos!

    @Inventor89
    one domestic company made it specially for a private customer, and the piece i bought was a remain (?) that was left from that, so i bought it per kilo… if i wanted a new piece that thick, i had to order a board 2×3 meters – 500 euro ! ! ! ….but these two kilos were two euros! …not much of a help?!!

    Inventor89 on January 30th, 2012 at 6:47 am

    Were did you buy the plexi glass that thick?

    mixcev on January 30th, 2012 at 6:47 am

    @Flogo85
    …sorry, no idea…. look at the chips datasheet, they covered some troubleshooting in it…

    Flogo85 on January 30th, 2012 at 6:47 am

    hi, cool tower :)

    maybe you can help me.
    i think the lm3916 is too sensitive,
    any idea how to get the light slower?

    and the first ~4 leds are very bright in comparison with the others,
    any idea how to solve that?

    thanks a lot.
