You can find some previous posts on the event here.
"Part party, part mixer, part Science Fair, and part performance, this is an informal chance for geeksters and the geek-curious to come together, relax, and discover new sounds and drink complimentary cheap beer. The evening is a gathering of inventors of new instruments and music technology. Featuring circuit-bent toys, custom software and patches, interactive digital and visual instruments, custom electronics, electricity-powered noisemakers, DIY robots, and new acoustic instruments. And it's open to everyone from hard-core hackers and newcomers to music lovers who want to learn about the DIY music scene."

Volta Quadrature LFO

Volta Quadrature LFO from Matthew Davidson on Vimeo.
"Volta can be used to create a quadrature LFO. A quadrature LFO has four outputs with the phase shifted in 90 degree increments. This produces the sine, cosine, inverted sine and inverted cosine. A quadrature LFO is useful for frequency shifters, barberpole effects, quad panning, phasers and so on. In this demonstration, we'll use our quadrature LFO to modulate the waveform animation section of a Livewire Audio Frequency Generator oscillator, then we'll play with the LFO waveforms to create some syncopated timberal animation - all in sync with our project."
