8M Light Sensor Sound Module

It doesn't come with instructions, but most of what you need to know is right on the listing. Once switched on, it only works when the sensor sees light, and immediately quits when dark again. It does have 8mb of memory and acts like a flash drive when you plug it into the computer (using the included cable). After you delete the pre-installed sample song, you can put any amount of songs up to 8mb. COMPRESS YOUR FILES if you want to put on multiple songs! (You can do that by ripping them again to lower quality, or going online to sites that do it free with a quick upload, compression, then download.) The speaker is okay (better than the kind in musical greeting cards, but nothing fancy), and lower quality mp3 files will be sufficient. I put four songs on mine and it works great. I had to play around to figure out how to play the songs in a particular order-- You need to RENAME the entire file title to "1", "2", etc. if you want them to play in that order. Any other effort with using lead numbers, or multiple letters, or anything else doesn't work for this. Once I just made them "1" ,"2", "3", "4", my songs played in exactly that order. It will ALWAYS restart at #1 song after it goes dark and back to light. But it only plays through your song(s) one time and stops until you reset it (dark, then light again). The on/off switch is labeled, but the volume is not; it's just a tiny slider near the one battery on the opposite side of the panel from the on/off & micro usb port. All-in-all, this little thing is pretty nifty, does well considering its size, and worth the money. I got this one to put inside of a gift box and it will play when the gift is opened. It has adhesive on the back so it can be stuck easily inside. Except for fussing around with the song order thing, it took about one minute to delete their file and transfer mine. Very easy to use! Your PC will automatically install the driver, so there's little to do. Thumbs up!

I had to search through dozens of options to find a sound device small enough for my applications, and this is it! Besides the fact that it fits wonderfully in a small ring box (only 2" of internal clearance), but it performs far better than I expected for anything in this price range. The sound quality is great, and it has a small volume control lever that can take it from mute all the way to painfully loud! In addition, setup was literally drag-and-drop easy. Once I connected a usb cable to the computer, it immediately recognized it as a simple usb storage device. I simply deleted the test file and dragged my own MP3 file to the folder. Then eject the device from the computer and unplug. After all this, it still managed to impress me with the quality of sound. While it definitely isn't going to be as nice as a home stereo or a $900 smartphone, it still very faithfully reproduced the music in clean, clear mono. This is definitely the best deal you will find for a small sound chip with a speaker. All of this for only $12! I will definitely buy more of these for any and all future projects requiring a sound chip!

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.

While it was easy to setup I was having an issue with the sound cutting out and heavy static. I found they specially need 3.6v batteries. I had swapped them out for a fresh set of 3.0v button batteries. the volume control has 3 levels but for me level 3 doesnt work

Come on man. Nowhere does it say on this product that it ONLY works on a PC. In other words, if you only have Macs as I do in your home, you're SOL. The product description of this thing says "Recommend using Windows computer and not MAC." Recommend is different than "THIS SPEAKER WILL NOT CONNECT AT ALL TO ANYTHING OTHER THAN A WINDOWS PC." And it's not expensive enough to warrant my time returning it. But hey, at least I have this fun little light-sensor speaker that plays whenever I want to hear a Chinese pop song. That's nice. Right?

Just received my light sensor sound module. I connected it to my PC using the provided cable and downloaded my MP3 files. Then tested out the light sensing switch and this little device worked perfectly. It was ready to use in my craft project within 5 minutes of taking it out of the package. One added feature that I didn't notice in the instructions is that you can add multiple MP3 files. So, if you want to put a personal message in one MP3 file, then perhaps a full length song in another MP3 file, it will play them consecutively. When the light activating switch is exposed to light, the device will start playing the MP3 files from the start of the track. Once the switch is back in darkness (no light), the device stops playing. When exposed to light again, it will start playing the MP3 files from the beginning again. Exactly what I wanted. I could use this device in dozens of other craft applications if it had a setting that it would play the MP3 files at random. That way I could load it with lots of MP3 sound clips and everytime my craft project was "opened" it would play a different cool sound effect. But I am very satisfied with this device as it has high quality sound and works exactly as described. I already purchased several more of these cool devices.

I was very impressed with this little device. So much so that I bought a few more. Ended up making different gift boxes for Christmas each with a light sensor audio module. It took some creativity to make it so the modules were hidden and the light sensor was positioned but worth the effort. The audio level is also quite clear and the device is really easy to use. I never had any issue connecting to my computer. My only complaint would be that once I moved a track onto the device, it seemed that I could not replace it. I could delete the track and add a new one BUT the space would not become free from the deleted track. Almost like once the space was used, that was it. Maybe it was me but seems like these cannot be reused for multiple events.

Worked great until it didn't, which was way too soon, less than a nine months. I tried new batteries and reformatting but to no avail. Even under direct-uninterrupted light, playback stopped at random times well short of completion. Update - After seeing my review, the seller provided a full refund.
