This soldering practice kit includes two 12V batteries, adjustable sensitivity, and a circuit board with mesh holes for visibility. Designed for school learning and party fun, it helps develop soldering skills and basic electronic knowledge.\u003c\/p\u003e\u003ch2\u003eHow the Sound Activation Works\u003c\/h2\u003e\u003cp\u003eThe kit uses a microphone to pick up sound, which is amplified by a transistor and sent to a KA2284 level indicator chip. This chip drives five groups of LEDs: the louder the sound, the more LEDs light up. A sensitivity adjustment knob lets you control how responsive the glasses are to ambient noise. When rotated left, sensitivity decreases; rotated right, it increases.\u003c\/p\u003e\u003ch2\u003eWhat You Get in the Kit\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLED glasses frame (to be assembled)\u003c\/li\u003e\n\u003cli\u003eCircuit board with pre-soldered components\u003c\/li\u003e\n\u003cli\u003e2 included 12V batteries (type 24A)\u003c\/li\u003e\n\u003cli\u003eThrough-hole soldering components for assembly\u003c\/li\u003e\n\u003cli\u003eUser manual available for download\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho Is This Soldering Project For?\u003c\/h2\u003e\u003cp\u003eThis kit is ideal for students, hobbyists, and anyone learning to solder. It requires basic theoretical knowledge and some soldering experience—not recommended for complete beginners. Schools use it to teach mechanical assembly and electronic principles. The finished glasses work great as a party accessory for concerts, raves, or festivals.\u003c\/p\u003e\u003ch2\u003eAssembly Notes\u003c\/h2\u003e\u003cp\u003eBefore starting, download the illustrated manual from the Amazon product page. The board has clear labels and through-hole pads for easy soldering. LEDs are mounted on the outer side so they shine away from your eyes, causing no visual interference. The mesh holes in the board allow you to see through the glasses when worn. Remove batteries when not in use to save power.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eDoes the kit include batteries?\u003c\/h3\u003e\u003cp\u003eYes, it comes with two 12V 24A batteries. You can disassemble and replace them later.\u003c\/p\u003e\u003ch3\u003eDo I need soldering experience?\u003c\/h3\u003e\u003cp\u003eBasic soldering skills and electronic knowledge are required. The kit is a practice project, not a beginner-first build.\u003c\/p\u003e\u003ch3\u003eHow do I adjust sensitivity?\u003c\/h3\u003e\u003cp\u003eUse the button on the board. Rotate left to lower sensitivity, right to increase it. If the glasses don't respond to sound, try adjusting this.\u003c\/p\u003e\u003ch3\u003eWill the LEDs hurt my eyes?\u003c\/h3\u003e\u003cp\u003eNo. The LEDs are positioned to shine outward, away from your eyes, and the circuit board has mesh holes for outward visibility.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Source\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2x 12V 24A batteries (included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLED Driver IC\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eKA2284 level indicator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSound Input\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMicrophone with transistor amplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensitivity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAdjustable via trim pot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eThrough-hole soldering\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGlasses frame, circuit board, batteries, components\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"MiOYOOW","offers":[{"title":"Default Title","offer_id":58075596325167,"sku":null,"price":25.01,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/4478\/7503\/files\/mioyoow-sound-activated-led-glasses-soldering-kit---diy-stem-project-for-learning-electronics-1.jpg?v=1781499283","url":"https:\/\/toysforkid.co.uk\/products\/mioyoow-sound-activated-led-glasses-soldering-kit-diy-stem-project-for-learning-electronics","provider":"Toys For Kid","version":"1.0","type":"link"}
