This is one of two portable speaker systems i wanted to build. I used the LM386 circuit from my previous instructable and incorporated it into this portable speaker system. It is a single channel (mono) speaker system which lights up blue in the background when you turn it on. I hope you enjoy this one and feel free to give me suggestions or ask me to clarify anything that may be confusing.

"Imitation is the sincerest form of flattery." Great job on this featured instructable.
ahah! Krmartin3, of course in retrospect my compliments are for your original work! ;-)
Guess i won't be replying this politely if someone stole my stuff.Just posted it in the forum(should get the attention of the instructable staff).He is hopefully going to get Booted out of this site.
very good tutorial, thanks for sharing!
He stole someone's Instructable(copied everything)<br> see for yourself<br> <a href="http://www.instructables.com/id/Portable-Speaker-1/#intro" rel="nofollow">http://www.instructables.com/id/Portable-Speaker-1/#intro</a>
Totally agreed the first instructable is one of in my favourite list.
i agree i jus wanna make a worth one popular
this isn't &quot;Making a worth one popular&quot;... <br>this is stealing someone else's work and claiming it as your own. <br>It's plagiarism. <br>You didn't even bother to give credit. I might have seen it okay if you at least posted somewhere that it was not actually yours. <br>Still even, you should post the link, and not steal a whole instructable if you want to make someone's instructable more popular.
Have you anytime read the rules or regulations if not you seriously need to spend time on. Secondly please stop bragging about things vomiting senseless stuff. If you really agree with me you should have at the start or end atleast for keeping your dignity and respecting have mentioned the original source from where you have copied. Its ridiculous ! Utter shame !
Same here,the first one has been on my favourite's list since i joined this site, sharkupsantosh just copied it &amp; is given a pro membership(for a featured instructable),i was like WTF man.........he got a pro membership just by copying an instructable!!!.
Looks good! The speaker is 8 ohms.....how many watts? Thank you.
hello I'm from Brazil and would like to know if I need to change anything if they put a more powerful speaker and how do I make one with 4 speaker and good sound quality. and congratulations for the very good tutorial
We use mono Pin (single input) so we use single speaker. If We use Sterio pin (left,Right) audio can b played.use sterio pin and configure it and connect to two speaker. <br>upto mee i can make only two way sound but not 4 way.... <br>Sterio..pin configutarion <br>
