- The DIY electronics tool set is clearly labeled, easy to assemble and illuminated to enable multiple effects in a compact kit. - Arc support function: the wire at the end forms a spark arc that can be ignited, enabling visual demonstrations of electrical arcs. - Innovative arc speaker concept: an arc flows through the air to generate air vibrations for music playback. - Coil module for audio: allows playback of music from a mobile phone or computer, but the sound output is very low. - Key attributes: function includes arc effects, lighting, arc speaker capability, and audio playback; compatibility with smartphones and PCs; compact DIY kit design. - Use scenarios: - Education and hobby projects in a home workshop or classroom to learn electronics and visual effects. - Demos at maker fairs, science events, or stage setups for live visual-audio demonstrations. - Ambient or experimental displays that combine light arcs with subtle audio playback from a connected device.
