Acrylic Rod Lamp With Bubble, Fun Music Visualization Series of Small Projects.

Hi, this is first post of my works, I'm very glad and appreciate the sites. Although the finished work couldn't be prefects, I still try my best to do it. Please give me more encouragement, I will give your more exciting work. Thanks, everybody!  

Music visualizer is composed of four development boards, 111 acrylic rods, and 259 WS2812B lamp beads

Main material:

• Acrylic rod & trunking box
• module MAX9814
• WS2812B lamp beads. Thanks for leadsintec support it.

Project materials ready: Acrylic rod and trunking box with removable cover

Processing material

Prepare sound module MAX9814 and lantern WS2812B.

The MAX9814 is a low-cost, high-performance microphone amplifier with automatic gain control (AGC) and low-noise microphone bias. The device features a low-noise front-end amplifier, variable gain amplifier (VGA), output amplifier, microphone bias voltage generator, and AGC control circuitry.

● Automatic Gain Control (AGC)

●3 gain settings (40dB, 50dB, 60dB)

●Programmable operating time

● Programmable action and release time ratio

●The power supply voltage range is 2.7V～5.5V

●Low THD: 0.04% (typ.)

●Low power shutdown mode

●Built-in 2V low noise microphone bias

lantern WS2812B.

Its main features：

Intelligent reverse connection protection, power reverse connection will not damage the IC.

The IC control circuit shares a power supply with the LED point light source.

The control circuit and the RGB chip are integrated in a 5050 package component to form a complete external control pixel.

Built-in signal shaping circuit, any pixel receives the signal after waveform shaping and then outputs it to ensure that the line waveform distortion will not accumulate.

Built-in power-on reset and power-down reset circuits.

The three primary colors of each pixel point can realize 256-level brightness display, complete the full true color display of 16777216 colors, and the scanning frequency is not less than 400Hz/s.

Serial cascade interface, can complete data reception and decoding through one signal line.

When the transmission distance of any two-point transmission does not exceed 5 meters, there is no need to add any circuit.

When the refresh rate is 30 frames/second, the number of cascades is not less than 1024 points.The data transmission speed can reach 800Kbps.

The color of the light is highly consistent and cost-effective.

Main application areas：

LED full-color light-emitting character light string, LED full-color module, LED full-color flexible light strip and hard light strip, LED guardrail tube.

LED point light source, LED pixel screen, LED special-shaped screen, various electronic products, electrical equipment marquee.
