DIY Bluetooth Speaker Kit

This STEM toy lets children aged eight to fourteen build a working Bluetooth speaker from wooden parts, circuits and supplied tools. No soldering is required and a step-by-step manual plus video guide walk the builder through assembly. The finished unit includes a comfort-grip handle for carrying.

Sustained playback with LED lighting

The speaker runs on four AA batteries that are not included, so continuous use depends on the cells chosen rather than a fixed runtime figure. Twenty dynamic LEDs pulse in time with the music during operation, adding visual feedback without a separate power source. Performance remains steady while the batteries hold charge.

Thermals noise and power draw

Low-voltage circuitry keeps the enclosure cool to the touch during normal listening sessions. Audio output stays clear at typical indoor volumes and the LED display adds no audible fan or coil noise. The kit weighs 0.63 kilograms and measures one inch on each side, making it compact for desk or travel use.

Questions about this item

How loud does the built-in 20 LED light show get after hours of continuous playback?

The 20 LEDs pulse to the music rhythm without adding audible fan noise or measurable heat, so the speaker stays quiet and cool during all-day use.

Which batteries must I supply before the completed speaker will power on?

Four AA cells are required and are not included in the kit; insert them into the battery compartment after assembly to enable Bluetooth audio and the light show.

Will the 1-inch cube enclosure still pair reliably with an older phone that only supports earlier Bluetooth versions?

The kit uses standard Bluetooth connectivity, so it pairs with legacy phones and tablets just as it does with newer devices.
