***SONICA 1 - Headphone Amplifier with TPA6120***
Sonica 1 is a rebirth of an older design of mine. A few years back I designed a small PCB for a headphone amplifier, based on BurrBrown (TI)TPA6120A2 chip amplifier. I made a power supply on a piece of test PCB with a toroidal transformer. The end result was quite pleasing and I have used it since then as my main source for music at home, whenever...
Combines Bluetooth 3.0 Audio Module with Class-D Amplifier and 4.2V Li-ion Battery Charger for wearable/portable audio projects.
Dimensions specifically designed for Dual 18650 Pack for use in bluetooth stereo headphones or portable speakers.
In theory, you should be able to customize it by directly plugging it into a PC with a USB data cable and customizing it with Silicon Labs iWrap software. I...
LED Music Spectrum generates the beautiful lighting pattern according to the intensity of music. It contains many RGB LEDs which not only turns on and off as per the music but also change color according to the music.
Here is a Music Spectrum using NeoPixel RGB LED Matrix and ARM microcontroller.

Class-A Headphone Amplifier using IRF610 and LM317 as CCS.
The original project and overall idea is to [this guy].
Note: Only one channel is shown.Please, also note that the 100k trimmer resistor should be adjusted - see diyaudioprojects.com for more information about that.
Be careful when connecting LM317 and IR...
This is a miniature 0.7W amplifier with adjustable bass boost, gain, and volume controls. Uses 1/8" (3.5mm) headphone jacks on the input and output. Powered by USB or 9v (4-12 VDC, max of 15 VDC). I designed it to use film capacitors and Nichicon audio grade electrolytic capacitors wherever possible in order to preserve the signal and reduce noise. An isolated power supply such as a battery is...

A CS42448 multi-channel audio codec breakout board for the Teensy 3.5/3.6
*note* This PCB does not provide any analog filtering or biasing for the input and output signals and must be done externally. Please refer to the CS42448 data sheet for more info.
This board breaks out the 6 input and 8 output differential audio signal pairs of the CS42448. The digital signaling (TDM) and control (I2C) a...
