Seanchai Library opened in March of 2008, presenting stories live in voice at the former West of Ireland charity estate. Over the years, thousands of stories and a variety of presenters have contributed to a community built on sharing literature: novels, stories, and poetry.
On Sunday, March 19th (2023) The Library celebrated 15 years in #Secondlife

Glowy sonic light bars in the courtyard at the V&A, reacting to visitor movement, and radiating an astonishing quasi-religious sense of communal artifact worship. Very black monolith.
Dolby's Brett Crockett, Craig Eggers and David Yang demo Dolby Volume features to media and influencers at the Gramercy Park Hotel.
Some minor repairs were all that were needed for the Ernie Ball Volume Pedal. Very solid and built to last. These have a minimum of internal parts. With maintenance and repairs these could last forever.
Ink tests at the back. This journal has weird paper: it liked purple inks, but basically no other colour worked, they just beaded, pooled and refused to dry.
The audio compressor or a unity-gain amplifier having an expansion of 3 db and a compression of 12 db around an average level of approximately 45 db below 1 volt at an impedance of 100.000 ohms. The compressor is inserted after the microphone amplifier. The incoming audio signal is amplified by U1a and applied to the diode compressor through C1. The diode compressor is essentially an L-pad attenuator, with R1 forming one leg and diode D3 for the other leg. Diode D1 rectifieds the audio signal and applies the resultant DC voltage through R2 to diode D3. The impedance of D3 varies almost logarithmically in inverse porportion to the DC voltage across it. Diode D2 protects filter capacitor C2 from any reverse polarity switching transients that may be applied from the output. The curves of Fig-2 show that about 15 deb attenuation is availaBLE. A portion of this loss is made up in the opamp, thus permitting installation of the unit as a unity-gain amplifier with an expansion of 3 db and compression of 12 db. Total conasumption is approximately 4mA. The frequency response of the compressor for various input levels is shown in Fig. 3. A tape recorder using this automatic gain compressor has been successfully used to report events from the quiet of an empty hall to the noisycockit of a small private plane.
