Ruby is a battery-powered amplifier.Ruby has many shades of sparkly clean all the way up to a great, natural overdrive. The input buffer helps to retain treble detail going into the LM386 chip. As you increase the Volume, you will start getting nice breakup. [more]

The amplifier is very popular among DIYers around the world.CMoy Amplifiers are named after Chu Moy, who designed the pocket battery-powered amplifier and published the paper on his website. These amplifiers were designed to give audio fidelity and power to headphones. A CMoy is powered from a single 9V battery and can last at least 40 hours of listening.This amp build around OPA134PA op-amp.[more]

This is an 8 ohm attenuator built using an 8 ohm L-Pad. 4, 8 and 16 ohm versions are possible. The 4 ohm version would be built using a stereo 8 ohm L-Pad with the terminals wired in parallel. [more]

This effect was developed due to a couple of wonderful guitar devices: SansAmp GT2 (by Tech21) & Guv’Nor (by Marshall). The Overdrive section were taken from SansAmp and Tone-control (EQ) section were taken from Guv’Nor. The next features were added: hi-impedance (1 MOhms) INput to decrease pickup’s signal degradation and bufferred low-impedance OUTput to satisfy any next circuits (long cables, low-impedance mixer’s INput and so on). Scheme is deprived next flaws of SansAmp: pops on switching on/off of the effect, strong noise in pauses, no “mid” control EQ. [more]

This is a musical sensor interface using the CREATE USB microcontroller: a hybrid network of tangled audio technology, based around turntable decks, guitar strings and optical sound designs.This project wanted to merge several of the most crucial audio technology inventions from the previous century into a hybrid object. The inspiring technologies include the phonograph, optical sound on film, the amplified guitar, and the computer. Each represents a different approach to generating, transmitting and/or encoding vibrations, from the spatial through the electrical and optical to digital bits, and each with its own expressive leverages and characteristic morphologies. This project embodies a continuum of audio technology interaction from the most physical hands-on of the vibrating string, to the abstracted turntable control of pre-recorded data, to non-physical control data in optical and electronic form, and finally to the completely abstracted and malleable digital domain.
