When idle, it displays time in bold blue digits (5.04W x 1.26H compact design). Connect a 5V power source and play audio via your device to activate 18 dynamic light patterns that pulse with sound frequencies. Perfect for intermediate soldering enthusiasts to refine SMD techniques while creating a functional decor piece. Core Features Rhythm Sync Technology: LEDs transition between 18 programmable modes, reacting to music beats via built-in microphone. Auto-Dimming Night Mode: Adjustable brightness schedules reduce light intensity during preset hours. Precision SMD Assembly: Tight-spaced components challenge soldering accuracy (recommended for users with prior experience). Memory Retention: Custom settings like flash speed\/sensitivity are saved during power cycles. Technical Specifications Operating Voltage: 5V DC (USB-compatible power input) Display: Red LED with 6-digit time format (HH:MM:SS) Material: Flame-retardant FR-4 circuit board Dimensions: 5.04W x 1.26H Skill Development Focus Ideal for advancing surface-mount soldering skills, this kit includes micro-components requiring steady hands and sub-1-second iron contact. Assemble resistors, ICs, and LEDs to master circuit integration while building a tech-forward decor item. Usage Scenarios Interactive wall-mounted display for living spaces Workshop tool for teaching intermediate electronics Ambient desktop accessory with functional utility Assembly Guidance Required Tools: Soldering iron (25-40W), solder wire, tweezers (not included) Critical Tips: Verify polarity markings before installing diodes\/ICs Prioritize soldering complex components first Use anti-static gloves to protect sensitive modules Support: Includes downloadable English tutorial; contact support for troubleshooting. Safety Notice Avoid prolonged soldering iron contact (\u0026gt;1 second per joint) to prevent component damage. Ensure workspace ventilation and circuit integrity testing before powering on.\u003c\/p\u003e","brand":"ONEHPDIY","offers":[{"title":"Default Title","offer_id":45183209341043,"sku":"WBHDWB0D8KV56Q6","price":32.07,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/1958\/6419\/files\/71kORQsd74L.jpg?v=1783411304","url":"https:\/\/slickpurchase.com\/products\/onehpdiy-smd-soldering-practice-kit-6-digit-led-digital-clock-with-music-spectrum-display-diy-electronics-project-stem-gift-for","provider":"Slickpurchase","version":"1.0","type":"link"}
