***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...
This is a Raspberry Pi Zero W hat/shield with USB MIDI input, stereo audio output, 3 user-configurable buttons and OLED display.
To use as an audio card, enable PWM audio output by adding `dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4` at the end of *config.txt* file.
Remeber that HDMI audio output is the default; use `raspi-config` to force output to 3.5mm audio jack.
If you can't find 47uF...
**This is an experimental electronic circuit, without any warranty.**
Class-A Mosfet Headphone Amplifier
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...
El TDA2003 es un amplificador económico que provee hasta 3.5A de corriente en su salida. Además de usar pocos componentes alrededor de el.
Puede usarse con el radio de un auto o con bocinas de mediana capacidad.
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.
