This kit allows you to assemble your own stereo speaker with wireless connection Bluetooth 5.0, playback from USB and TF card, and built-in FM radio. The set is designed for DIY enthusiasts, students, and anyone who wants to learn to solder electronics on a practical project that will be genuinely useful once completed. It includes a laser-cut acrylic case, two speakers, and a separate music indicator board with 12 LEDs. The finished speaker is powered via a USB cable from a standard charger. The product is delivered in individual parts, and the soldering and assembly are carried out by the user themselves.
The main Bluetooth module with its own amplifier is pre-assembled and tested along with the front panel, so only the speakers, power supply, and indicator need to be connected. The panel features a status display, USB input, TF card slot, AUX input, and buttons for volume, track switching, playback, and mode change. A phone or tablet connects to the speaker by searching for the device named JQ-BT. The music level indicator uses four LM358 chips, and its sensitivity can be adjusted with a trimmer on the back of the board. During playback, the LEDs light up from the centre to both sides in rhythm with the music.

Before assembly, it is necessary to remove the protective film from the acrylic panels and clarify the placement of the individual boards. Components are soldered from the lowest to the highest, and for electrolytic capacitors and LEDs, polarity must be observed, with the longer lead of the LED being positive. After soldering, check all connections for cold joints or shorts, and only then connect the power supply. To receive FM radio, it is necessary to solder a suitable wire to the antenna point of the module, which can be coiled inside the case. The speaker is turned on and off with the remote control, switches modes, mutes the sound, adjusts the volume, equaliser, repeat mode, and source between USB and TF card.
The kit combines soldering practice with a result that can be used daily as a speaker for a phone, computer, or as a radio. Thanks to the assembled Bluetooth module, assembly is manageable even for beginners, and the main soldering work takes place on the indicator board with standard lead components. The kit is suitable for electronics clubs, educational settings in schools, and as a gift for technically inclined children and adults. Upon completion, you will have a speaker with FM radio and a light effect in an acrylic case.
