Icstation Recordable Sound Module, Button Control Sound Chip 8M MP3 WAV Music Voice Player Programmable Board with Speaker for DIY Birthday Music Box Greeting Card Present

This product is perfect for adding personalized sound effects to any project easily! I decided to use this device in a lightsaber hilt I was working on so that I could add sound to the saber. It was easy and stress-free to add the audio file I desired for my project onto this device. It works really well and is reliable. The soldering that keeps the components and wires connected to the PCB is well done. The speaker is compact, light weight, and produces a surprisingly clean and loud sound. You do have to supply your own power supply but it is easy to connect it and you can decide how you wish to power the ingenious module. You can upload a decently long file and if you wish to change the audio file, it is very easy to do so. It's a really fun module to play with and any project you decide to use it in is instantly improved with the addition of this device. I highly recommend this product!!

Very good unit! It will hold any common sound file. Good and clear sound for such a small system. It is very easy to use. Plug it into the computer with the supplied USB cable - a folder will pop up on your desktop (depending on your settings in windows) - Mac it will show as an extra drive. Open it, throw the test file out, delete it from your trash and simply drag your own file onto the folder/window - done. Attach 4.5V - 5Volt push the start button and the sound plays. The unit, most likely will be at full volume. Volume can be turned down/up via the small trimmer on the circuit board, next to the on/off button cables. Important here is not to mount the speaker flush against a solid surface, it will dampen the sound and lower the volume. Rather build a small frame that fits around the speaker and is open to the front and back. Secure the speaker properly to the frame or cut-out so it does not cause any rattling at certain frequencies (small dabs of hot glue on the very outside edge will do). Also important is not to use a sound file that is recorded with a volume level that is border-line clipping. Those files will cause a distorted sound from the small speaker. Better to use a file that has a mid-range volume (can be adjusted in any software that has sound editing capabilities) and turn the volume up on the small unit. This will ensure a cleaner sound.

I bought this because this was the only reasonably-priced audio device of this type that was available for Prime delivery. I should have read more of the reviews, because it does not include any instructions whatsoever, it requires a specific USB cable to connect to a computer in order to load an audio file onto it (I originally thought it was something where you could push a button on the device and just record onto it), it does not include the power source (i.e., no battery), and it is ambiguously triggered (the descriptions don't make a lot of sense to me because they aren't written very well). Customers shouldn't have to rely on other customers' questions to get important product information-- The seller should either write the descriptions out better or should get someone else to write this information out for them. NOTE: I ended-up making this work by powering this with a portable power bank-- I got one at Wal-Mart that had a micro-USB cable included. It cost under $10 there, but for all of the trouble this put me through, and how bulky the final set-up ended-up being, I'd say you might be better off just buying a more expensive audio player with the power source and instructions already included. The other thing I found out was that there was a track that came with the device, which kept playing after my audio file would finish playing; to fix this, I had to plug it into a Windows PC (my Mac wouldn't work) to reformat the entire thing so that it would clear all the way to it's default settings. The only "pro" about this thing is that, when rigged-up correctly, other reviewers are accurate when they say that the speaker is loud and has good sound.

Product is great. Works as advertised. However, when I received the delivery notice and the photo of the very light weight package on my porch I went to get it and it wasn't there. Since we had 25 to 30 MPH winds blowing at the time of delivery I went looking for it and found it on the empty lot next door heading toward the water. A little consideration for the weather conditions on the part of the delivery staff would help. Just a thought.

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

A very neat product. Depending on your MP3 size you can get significantly more than a minute out it. The only real issue I had was that it doesn't come with a manual. Because of this, I don't have a clear idea of what the switch does. At first, I thought it switched the device from PC accessible to battery powered, however, the onboard memory was available in each position. When I applied 5Vdc the device would not start until I toggled this switch. In one of the positions, it accepts the DC power from the leads and the power LED is default off (I assume to conserve power) and only flickers dimly when it is actually playing. I have not tried adjusting the volume. Another review said it was possible but it is already plenty loud. The MP3 I wanted to play was softer than the default MP3 it came with so I recompiled the file with a louder default. Volume increases the current draw. See current measurements below. The oddest thing about this device was the mode where it was connected to the PC (where you upload your MP3 file). The LED light came on to show it was powered but I had to fiddle with my cable a bit to get it to register. (I have a very good cable so I am pretty sure it was the connector.) I run Windows 10 so it was able to run on that system. The weird thing was that I couldn't get it to play at first while connected to the computer despite the memory being 'seen' and LED light being on. However, as I started to pull the micro USB cable out, just as the device was loose enough NOT to be seen by the computer as a drive...suddenly it would play if I pushed the button. I would love to see the instructions. Is this a loose connection or an intended function. No idea but I can work with it and its fairly reliable. There is 5Vpad where the DC power leads are. These are the connections I used for all my tests. There is also a set of pads marked 3.7Vdc that have no leads attached. I have no idea what this is for. Is it an alternate DC in? Is it a DC out? I suppose I should have checked when I had the meters out... Oh well. Anyway, it would have been 5 stars if it came with a manual with the specs. The power draw from the device is 60mA maximum (from the MP3 default file) and about 30mA nominal. Using a variable DC supply I saw that it functioned down to about 2.9Vdc. I ordered a cheap LIR2450 coin battery and charger 4pcs of Li-ion LIR2450 Rechargeable Button Batteries, 2450 Coin Cells, with Charger . This should run the thing for hours (3.6Vdc, 120mAh nominal). I am getting a battery holder from ebay. The Amazon ones are bit expensive. Looking at the specs of the LIR2032 (3.7Vdc, 35mAh nominal, 70mAh maximum), this would likely work as well for a much shorter time, but still at least an hour. Update: I downloaded the instructions! Paragraph 3 is still not explained but I have a bit more information. The 3.7Vdc lead is for a lipo battery and the manufacturer says that it will charge the battery when the micro USB is connected and powered. Yipe!

I have purchased 2 of these over the past year now for cosplay purposes. They are very easy to program and setup. I cut off the speaker and hook them up to larger speakers, run my own wires, lengthen the push button and add battery packs myself. I will probably be purchasing more in the future! Thank you so much!!! Very easy and useful product!

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!
