No use of amp or caps or resistors since am unable to understand the diagsThen why are you here? We can't help you if you can't read a schematic.
We don't know which LEDs you used. Maybe four LEDs in series need more voltage than you have.> my leds are much dimmer how to increase the intensity
Reduce the value of the missing current-limiting resistor.
Maybe the input signal level is too low so amplify it.
Bass sounds in music are loud and are in mono, not stereo.> even two set connected to diff channels left and right but both blink the same no diff in blinking, what might be wrong?
We design active filters to separate the frequencies.> how to seperate frequencies high mid low
without seeing your schematic then we don't know what you connected to what.what i did is hooked 3xtip31 to 3set of leds one with left and other with right and the last with combination of left+right but all blink the same with low intensity HELP
The circuit is HORRIBLE:
If the input is from a microphone, a line level or a headphones level from an ipod then you need an amplifier.> Amplify the input signal
How to do that have heard of LM386 or op amp($10) what they say to improve the signal but dont know the circuit moreover they are costly what i think isnt it. Also i have seen circuits where they dont use those but still get brighter display of LED's so am confused.
>Please let me knw how to amplify in cheap
You are simply shorting the two channels together which will destroy an amplifier if the input signals are speaker levels. Then all of your outputs are mono. You are supposed to use an audio mixer circuit to make mono. Some audio mixers are simply two resistors.>Bass sound in mono
I have done that in last strip of led right+left = mono isnt it ? if am not wrong
since during these many days i have found that connecting these two channels create a mid pass filter which is not with me
Because you simply shorted the left and right channels together so they produce mono exactly ther same.All blink same nothing diff and all with same intensity
There are many circuits on the internet that use inexpensive opamps to make active filters.> and lastly about separating frequencies
i have seen those but since am not a electrical student i am not aware of those, those are like cryptic symbols and am not able to understand.
A 1N4148 can be used if you have only 18 Leds or less. A 1N5404 rectifier has a fairly high voltage drop (a 1N4001 is lower) but will work. My solar garden lights have some 1N5817 Schottky diodes that will work great.sorry to jump in just here, but I was wondering, instead of the 1N4001, can I use another diode? Specifically, could I use a 1N4148 or a 1N5404.

It is a very simple circuit.hey audioguru could you gimme an explanation of how the led's glow when audio input is applied??
