FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA Description: Circuit functions: With the sound of music or other sounds, LED lights follow the rhythm of the sound (the speed of the sound) and flicker. After successful welding, you can feel the wonderful combination of sound and light. Working voltage: 3-4.5V (if you need a higher working voltage, please add a current limiting resistor on LED, usually tens of euro to 100 euro). Circuit principle: Sound-controlled LED melody lamp circuit consists of power supply circuit, microphone amplification circuit, LED luminous indicator circuit, power supply by JP input, C1 filter power supply circuit. MIC converts sound signals into electrical signals, which are coupled by C2 to Q2 amplification. The amplified signals are sent to Q1 base. Q1 drives LED to emit light. The louder the sound, the brighter the LED.

Description: This is an easy make four-layer round led dimensional cylinder kit, it's all use DIP components. It has more than 20 kinds of special led gradient effect. Some kinds of the effect is star-flashing and lightning effect, it also has many spin move effect and led breathing effect. All of the effects is gradual change light up instead of directly light up, that makes the led animation looks more gentle. you can hang it up on the christmas tree to simulate the star flashing effect. Soldering grids of each led layer greehand would look terrible. It has a dual use round acrylic that can as a template to hold the led in place, that help you to solder each layer of the led grids more accurate and the same level. On the other hand it also use as a case to reinforce the bottom. This acrylic template is important for quality soldering, it makes the led cylinder easier and more precise.
