This project is an audio amplifier based on TDA2050 and LM1875. This is not an ordinary project, but an attempt to make a PCB that is suitable for TDA2050 and LM1875 and has all the necessary circuitry on board – power supply, speaker protection, delayed turn-on and fast turn-off. This is achieved using the convenient […]

So far in this series we’ve had a diverse look at how Arduino can interact with a range of real-world devices from servo motors to ultrasonic range finders TVs to humidity sensors. Now we’ll see if we could get the Arduino to make a few sounds. We’ll actually do a bit better than that –

This post is a guide for people that are interested in my previous posts about dual monitor VGA hacking (see 1, 2 and 3). You will need: • A laptop or a computer with a VGA output • A breadboard (optional) and some wires or a strip board for soldering • Wire and breadboard jumpers

Have you ever struggled with audio settings in control panel in middle of a VoIP call? Or, wondered if the other guy can hear you properly? I have. My work requires great deal of remote conference calls using PC. The first thing I wonder always when starting is if my audio settings — mic volume,

This simple device simple plays a small tune at a random interval, between 5 and 30 seconds when the lights in a room go off. It can be cleverly disguised inside a tissue box, or inside or under any number of household objects. This is a vary simple project (my first audio project) and requires vary few materials, most of

Microsemi has announced a family of DSP chips. Called Timberwolf, it is described as a third-generation DSP architecture designed with a proprietary 4 MAC core, dedicated hardware accelerators, and two independent 16bit DACs in 64pin QFN and 56pin 3×3 CSP packages. “This field upgradable DSP platform, when combined with algorithmic firmware, can enable beam forming,

I already have one project where arduino outputs audio signal to USB speakers via software 10-bits PWM. In first, I was not satisfied with quality of sound generated via PWM. There are just not enough speed in arduino engine to run PWM well. For example for 20.000 Hz audio, PWM has to be at least 2

This project functions to display sound using vibration. You plug your iPod, computer, or TV into it and get tactile feedback representing the loudness of the audio. It can help deaf people to experience sound. Stuff you need: Arduino USB Cable Computer running Arduino software (www.arduino.cc/download/) Breadboard LEDs Pager Motors Three 100K resistors Six 220uF resistors
Representing audio through vibration with Arduino Continue Reading

Let the world know what you’re eating for breakfast with an 80’s style vocal synthesizer! This project uses an Arduino to send your Twitter stream to a voice generator chip called the SpeakJet. The setup that I use here can also be extended to other applications where you’d want to translate text into speech, some
