Very easy to use; almost an hour of lullabies

I ended up using this for a different project that my original purchase intent. The new project was a mini music box for my young son. I used an old phone charger wall plug and wired it directly to the red and white power wires on this board. I purchased a small plastic project box from Amazon and used a spare heavy-duty push button I had lying around. I drilled a few holes, mounted the speaker, ran the power cable, and mounted/rewired the original push button. Hooking this board up to my Windows 10 PC, it mounted as a flash drive and I deleted the existing song. I was able to then put almost a full hour of lullabies (as one continuous MP3) onto the chip and adjust the volume down very low. Pressing the button starts the music from the beginning; pressing it again stops it (or until the music runs out); pressing again starts from the beginning. I used an audio editor to combine multiple MP3s, level the volumes, then saved it with a very low bitrate; something like 22050 khz @ 16 kbps. For a simple quiet lullaby box with a tiny speaker, that rate was absolutely sufficient and in exchange, I was able to get 57 minutes of music on the 8 MB chip.

Great for adding music to works of art for people to listen to.

Simple, yet aesthetically pleasing to the ears, this thing puts out a good amount of sound. I'm going to use it to share songs that I've recorded with my clients that walk into my office. I'm a visual artist too, so I may have it attached to the back of a painting for added effect. It's very simple, you just plug it into your computer, add an mp3 file, solder a lithium battery to the board, charge it, turn it on, and press the button. Good to go. It's a no-brainer for my patients of all ages to figure out: 1 button makes it go. Things to note: 1. The USB port on the board will charge your lithium battery should you wish to solder one to the board. You can also power it with 5V usb via a separate soldered connection. You can simply cut a USB cord and solder the - and + to the board, then plug it into a power source, and it will work. 2. The tiny screw changes the volume. 3. Someone on Amazon told me that you can replace the speaker with a headphone jack by soldering a female 3.5mm cable to the wires that go the the speaker. I haven't done this yet, but I intend to try it so that my clients can put on some supplied headphones and hear the song. PS I love the song in chinese that came on my device. It's so catchy, I keep listening to it over and over. The song was "The Brightest Star in the Night Sky" by Escape Plan

The best card mp3 player

The best card mp3 player. Holds five minutes of mp3 (depending on sampling rate I suppose) super easy to program, just drag and drop! Volume is way better than I expected (I compared to greeting cards that I have heard). With a proper sound box for the speaker will be even better. Recommended.

Great for a beginner electronics enthusiast,

This thing works great so far, and the USB interface made uploading a file stupid easy. Ignore much of the negative reviews on this as it appears most of these reviews were by people who didn't bother reading what they were buying, otherwise they wouldn't have bothered. If you have the fundamental understanding of basic soldering and voltages, this should be easy to figure out. I attached a much better speaker to this and this sucker's loud. It'll be sure to turn heads after I slap it inside a Nerf blaster.

Great for music box!! I'm REALLY pleased with my project.

I made a light activated LED infinity mirror music box for my BF. I couldnt see the disk on mac OS 10.11.6, but it worked just fine in ubuntu. (Never tried it on Windows- I work to avoid it.) The sound quality is impressive. I mean, yeah, it's a 6$ speaker, you know? I'm not expecting sounds like my JBL's, right? But it's pretty good, considering. It soynds louder and possibly better in some ways than my iphone speaker. Not quite as much clarity, and zylophone had a bit of static when turned up high. I didnt realise it had volume control! The light sensor is auper sensitive- I had to hundle it in two layers of black gaffer tape to assure that onlythe led's for the mirror triggered the sound when the button for the lights is actually pushed. If you want the sound off, there's a manual switch! And the coun battery is rechargable via micro usb? This was 6$!!!!! I feel like I got a really cool little device for that price. It even has a little led to tell you it's charging that goes out when it's done. I feel kind of dippy that I didnt take a video of the finished piece so yoy could hear the sound. I realise it's not visible in the picture. It looks just like the image posted by the seller. Suffice it to say: you turn on the light and hear 'prototype 1' by Wintergatan (the marble machine band). Here's a picture of the finished project, for fun. The base panel hides all the batteries and power cords. Oh! The glue backing is VERY sticky. It stayed adhered to some black plasticorr.

This is fantastic!

So, I have a cool project where I am making a little music box that is going to be pulled along by a steam powered train and play candy themed music! This little sweetie (HA! See what I did there?!? ;) ) was just what the Candy Man ordered! I ordered it a day or two ago, and it arrived while I was at work today. Popped it out of the package, well packed and protected plenty on it's journey to me, and hooked it up to my PC using a Micro USB cable I had lying around. (It doesn't come with that, you have to supply your own.) I heard that familiar Windows 10 chime letting me know it sees it! Opened up finder, and there it was! It has a lovely little song loaded on it, and I listened to that, then offloaded it so I can fit my own music on it. I downsampled my music so I can easily fit my 5 songs on it. Transferred them over (it is a bit slow in transferring, but it worked fine!) and then ejected it. I scrounged up a charged single cel lithium polymer battery that will supply me around 4.2 volts when it's charged up and plugged it into the cable that is soldered to the 5v side. I pressed the button, and heard the lovely music I loaded on it wonderfully! I listened through to make sure all the songs worked, and they did wonderfully! I found that having the speaker in the air with minimal contact with anything amplified the sound very nicely and definitely rounded out the sound coming out of that tiny speaker! (1 & 3/4" or 35mm in size depending on where you learned math) The volume was a bit low, so I cranked the screw that allows the volume to be changed with a large, yet not gigantic philips screwdriver. BOOM! now it cranks! I'd definitely recommend this. If you need something to inspire your pure imagination, or need something like a spoonful of sugar to help a project sound it's best, this little fella will do you right!

Much smaller than most of the others.

Used this to build a custom Volvo door chime relay. Worked great and it "takes my breath away."

Works without much headache.

When I ordered this I did not know it would charge a lithium, so I had wired up a 3.3v up/down regulator to work with a pair of AA batteries. I used this module to upgrade an "Easy" button to say anything. It worked well, but it'd have worked better if I would have used a 5V boost module. It cut out sometimes with the 3.3v module when the batteries were getting low. That's entirely my fault. It's unfortunate the amount of 1 star reviews here, This little device saved me a lot of time (and money) over the much more expensive Adafruit Sound FX board series. Those boards have their own uses and are more advanced than this one. This one is quite easy to use out of the box, I had mine running and completely installed into my easy button within an hour. I would recommend this if you need something that just works. The Micro USB on the board contriibutes to this unit being very flat, so it's easy to stuff it into tight spaces.

I really love these.

These are great. Sure you could make your own, but why bother. Only real beef is that it isn't coded for playing multiple/different songs with a button press. Will play them all at once when the button is pressed. I haven't hacked into it to see if the chip can be reprogrammed ('cause who has the time!?!...which is why I purchased this instead of building my own). Work great to customize personalize toys (stuffed).
