Make your own colored LEDs
Thanks for the instructable - I made it with 10 LEDs in parallel. Couldn't get it working with a phone though, not enough power I presume - any advice to adapt for phone use would be appreciated.I also got the "speaker" version working with the LM386 (following the circuit diagram and using .5W, 8Ohm speaker and trying out different resistor values) but it would only pick up loud sounds spoken directly into the speaker - again, any advice to improve sensitivity would be appreciated.I

I sooo wish it did work!
tried this, does not work at all. whatever color you use, it doesn't make the led look different, the colors are too transparent.
Dude. A simpler way is to connect the leda positive to the speaker's positive and the negative to the negative or just earth it( ground) and it will react to the base..and for the speaker integration..attach a speaker inside the box. And then use a 3.5 1male to 2female splitter . insert the speaker and led jacks in the splitter and glue it inside the box. And let the male end come out that hole.. Now u can plug it into ur ipod or whatever and u get both music and lights.. Make sure u make room for the power input to power up ur speaker.. Probably a usb powered speaker will do best..

Could you use an lm358 instead of an lm386?
Something doesn't quite add up here. I'm using the NTE196 transistor, that brand's equivalent to the TIP31. The problem is that not one device I have puts out the requisite voltage through the headphone jack. It works fine if I manually apply a battery across the base and emitter but a headphone jack doesn't put that much out even with volume cranked all the way up. What are you plugging this into?
can you use the speaker wire after the amp for the input signal?
Nice tutorial :) But I must say... This MUSIC!!! Awesome. I had to follow your bro on SoundCloud immediately. A talented producer. Love it
Can i use it for android phones to plug it in mobile and let it beat
Could you use an lm358 instead of an lm386. the 358 seems to also work with sound but i dont want to blow that opamp
