DIY Bluetooth Speaker Box Kit, Small Transparent Electronic Sound Amplifier, Building Your Own Speaker Case, DIY Hifi Speaker for Teens, Kids, Adults(transparent)

No instructions at all!Product is not a diy kit.Most is the components come on ribbon tape which is designed for a machine to solder, as is the component board itself. The main chip arrived with bent pins. I solder electronics for part of my job and this kit would be nigh on impossible for 95% of people to do at home. You need to be very experienced and have kits that beginners just wouldn’t have or be able to use without experience. Do not buy if new to building electronic kits

It came with no instructions or QRS code to get them. All surface mounted components that are a challenge to the most experienced solderer. A video on YouTube shows a man building this kit however at the end it didn't work.

This kit is a mixed bag. First, the good bits - the display circuit board is decent quality, and all the stuff you need is included. The bluetooth receiver and amplifier are prebuilt, the speakers are OK, and most home constructors will be able to get a working bluetooth speaker out of the kit.The "visualizer" light display board is another matter. I'm reasonably good at soldering, and I have very good, small, soldering gear; it wasn't _that_ much of a problem, but it took a while. There are a lot of surface mount components to solder on. If you have a typical plug-in non-temperature controlled mains soldering iron with something like 2mm bit on it, just forget it. If you're used to hotplate reflow with solder paste, note that there are no solder paste masks included. You will need a responsive temperature controlled iron with a small tip, and good technique, to build the light display part of this kit.As is common with these kits, you can find instructions online. For the most part, construction is reasonably obvious.Beware that the MCU - see photo - is ambiguously marked. Looking at it with the writing right-way-up, pin 1 is bottom left, marked by the small ring and NOT by the big dot. If you solder it on the wrong way up, it gets hot and expires. The MCU, incidentally, is a weird 8051 clone, a significantly outdated 8-bit processor. Which doubtless explains the functionality, see later.The back of the board has 96 LEDs in 0805 packages - that's 1.25mm x 2mm - each of which needs to be soldered on. That's 192 tiny solder joints to not mess up on that side. On the other side there are eight 0805 resistors, the 44 pin MCU, and a few other bits and bobs.The acrylic case is like the unfortunate acrylic love-child of IKEA and Meccano. The parts kind of slot together and are held by tension on 2mm screws pulling against nuts resting in slots, and it's truly a pain to assemble. It looks kind of cool, though, in transparent acrylic.Once built, sound quality is not *bad*, but it's obviously not exactly HiFi. The visualizer board is the biggest disappointment, though. With 96 LEDs arranged as 12 columns of 8 LEDs, you'd think a spectrum analyser, or at least something level and/or rhythm sensitive, but no, all it does is, when there's a signal present on the left channel, it flashes lights in a random pseudo-spectrum-analyser effect that bears no relation to the actual music being played.Maybe, given an 8051 driving it, this is sort of understandable, but it's still disappointing.I had two of these kits and I messed up the MCU orientation on one, so I had to remove the fried MCU. (hence the flux residue and kapton tape in the picture). This is kind of a blessing in disguise. the LEDs are in a simple matrix, and any MCU with 20 GPIOs could drive them. On the one with no MCU, I will install an RP2040 on a daughterboard and drive the LED array as a 2x 6-bin spectrum analyser, using two of the analogue inputs, 20 outputs and some suitable software.I should reiterate that the bluetooth module and amplifier board is pre-built and works completely independently of the display board.Overall, a kind of fun project if you don't mind doing a lot of tiny soldering, but ultimately a pretty disappointing visualizer display.Has potential. Requires patience, a steady hand, good eyes. and a search onlinre for information.

Micro components not recommend for first timers but works fantastic FANTASTIC with good sound for the money

THER ARE NO INSTRUCTIONS CAN ANYONE HELP HOW TO PUT TOGETHER

The media could not be loaded. There are no instructions in the package and no instructions from the Amazon order page from the seller I managed to complete the project and it works fine

Where can the plan be found????Need help
