as cool as the minty mp3 is, you’ll probably want a minty amp to go with it so you can hear your fresh tunes at proper jaw rattling volume. and unlike limor’s awesome mp3 player, this one is a great way for a beginner to get started with hacking audio electronics.
i wana to be hacker …

“For ‘Beginners’??! I think not!”
don’t confuse the ‘do it yourself amp’ with the ‘minty mp3′. doing the former is fun. attempting the latter makes you an electrical engineer.

This is a super easy amp to build. You can get almost all the parts at Rat Shack, although the quality will be very poor. Dont try to take any homemade stuff on an airplane, but if you have hard to drive headphones, this will be a nice addition to any mp3 player….you’ll gain more bass, volume and a greater depth in the soundstage.
Good luck and have fun.

This is spot on – a little trickier than stuff i’ve done before, but the parts are cheap enough to allow for some screw-ups.

Yay! Maybe I can use it to listen to my guitar without plugging in that 200w s.o.b. What am I saying?! Bring on the deafness! This looks like a fun project but I can’t find a real good reason to actually go buy the parts. :/

hey metalhead, the better the headphones, the more power you’ll need to drive them. If you use something like Etymotic, or beyerdynamic, you’ll have to have an amp to get a good sound.
Additionally, diy amps are designed to bypass the stock amp. All stock amps are designed to power crappy little headphones that came with your player. IF you use something like this or any of the other hundreds of headphone amps, you’ll be very impressed.
Now, dont be so quick to judge.

Didn’t you already post this hack a few months ago?

This seems way similar to the Smokey Cigarette Amp (http://store.smokeyamps.com/catalog/product_info.php?products_id=31) I think I might make this in a Cigarette pack with plexy glass inside to prevent crushing. Cause you always need a mint after a smoke anyway. That would turn more heads the the headphone into the altoids tin. I could even save a space for a cig or two.
and don’t smoke. It’s bad for you ^_^

I bet anyone who gets caught at the airport with any of the minty devices probably will not be having a fun time tring to explain that it is only a MP3 player and amp.

very cool
i’ve been looking for a not-so-technical amp building guide
hackaday comes through with great hacks once again

Hi
can you send me a full set of schematic of the project, the instruction you have are in great details to much for me a schematic and list of parts you used will be great thanks.

how much louder will this amp be able to amplify sound, 2X 4X, Higher? Lower?
Posted at 6:41 pm on Jan 3rd, 2006 by winkler
this looks ok, but from radioshack it will be something like 25 dollars.
i bought a 5 dollar personal radio and found out how to hack it to add a male audio jack. it goes loud. srry, i didnt take many pics along the way. if i did i would put it up here…

hi, i was wondering if it was possible to add a speaker to this amp so that you could hook it up to your guitar or something like that?

For “Beginners”??! I think not! Did you actually read the pages before you submitted the story? It appears to me she didn’t want to make it easy on some of us, being she’s a graduate of MIT.
