DIY Bluetooth Speaker Box Kit Electronic Sound Amplifier - Build Your Own Portable Wood Case Bluetooth Speaker Sound - Science Experiment and STEM Learning for Kids, Teens and Adults

Easy to assemble. No soldering. Surprisingly good sound. A fun project that yields a useful product.

The media could not be loaded. The sound is better than expected, volume is nice. I picked this up for my RC trail trucks. It is heavy with 4 AA batteries, but Axial SCX24 lipo batteries plug right in. I used a sharpie to paint this box black. The build was super easy, but I would suggest a foam pad under the board. I will pick up several more for backup, and build my own box(s). The Bluetooth connection was simple and straightforward. The range is also good. I would suggest moving the power switch to the side panel. You should just pick one of these up for yourself.

Smaller than I originally thought. My nephew loves it though. He’s taken it apart and put back together multiple times.

Arrived very quickly and was easy to put together. Used for a LEGO radio and was able to fit in everything except the battery holder.

Great small project speaker. It produces more treble and mild midrange than bass, but it's still quite impressive. Assembly can be challenging, so young children may need adult supervision to help.

This 'build yourself' blue tooth speaker is simply amazing! It was a lot of fun to put together with knowing that it was something you built all by yourself. The instructions were very comprehensive and easy to understand. The materials are very sturdy and of exceptional quality. And the sound is absolutely superior for a speaker of its size. It's crystal clear even when turned all the way up. The compact size of this speaker makes it perfect to place anywhere when you need a little music in your life. I highly recommend it for all ages from 9 to 99.

Good quality

OK so after assembling the kit I noticed that as he would raise the volume he was immediately start to get distortion and then took it upon myself to hook it up to my oscilloscope and look at the waveform soon enough I discovered that the amplifier was putting out distortion after that investigation I started looking at the voltage control it appears that the amplifier works very well at 5 V but when you put four AA batteries you have 6.1 V depending on how much they charged hi suggest that the manufacture puts a lm7805 voltage regulator in line with the battery pack that way when you put in these New batteries and their overvoltage by a little bit it does not cause the amplifier to go crazy by putting a voltage regulator in line with the positive real I was able to eliminate completely the distortion and the unit works perfect
