The carriageworks gig - Cobramatic & Jondent - Live Recording
Thursday, 10th Sept, 2015.
The Carriageworks, Sydney.
https://en.wikipedia.org/wiki/Carriag...
Lots of fun and a awesome venue.
Our instruments consisted or two Buchla 200 roadcases (and a smattering of Eurorack).
The gig lasted for over an hour, but I've picked a small sample of under 7 mins to remember the night.
The visuals were all created using a LZX video Synthesizer

The Carriageworks - Opening night - Thursday 10th September
The Carriageworks is the largest and one of the most significant contemporary multi-arts centres of its kind in Australia. So it was a immense honor to play on the opening night. Our team comprises artists from NewSoundWaves... a group of electronic musicians.

Thredbo - NSW - Ski fields
Thredbo is an alpine village and ski resort in the Snowy Mountains of southeastern Australia.
The Mount Kosciuszko summit walk leads to the top of Australia’s highest peak. Wildflowers dot the mountains of Kosciuszko National Park in spring and summer.
The town has around 4,150 beds, but a permanent population of only about 471 people.[1] When the mountain is fully covered by snow, Thredbo has the longest ski runs in Australia, and this attracts around 700,000 winter visitors annually
Thredbo resort was developed by a syndicate of people who were at the time working on the Snowy Mountains Hydro-Electric Scheme.

Hyper Wein - NLC - Build notes
These are the build notes for the nonlinearcircuits Hyper Wein eurorack module.
The HW is a hyper chaos module based around the Wein Bridge Oscillator with vactrol control.
The video above is a test of this hyperchaotic circuit in a x-y plotter.
When building this module use 1% tolerance resistors.
"It really justs gets into its groove and bounces around at 1Hz or so, with the vactrol control unsettling it ...sometimes".
Andrew's build notes are here:
http://www.sdiy.org/pinky/data/Hyper%20Wien%20build%20notes.pdf
Headers first.
Resistors, diodes next.
Caps.
The vactrol ... I'm using a Silonex. NSL 32
The dot on the vactrol is the cathode of the LED side. On the PCB, K = cathode.
Next the pots & jacks:
I ended up using a 330ohm resistor for the LED resistor.
A footnote:
The hyper is a sensitive little thing.
Very much depends on components which need to be very accurate. It has a very narrow range of action.
Initially, all I was getting were sine waves. Andrew suggested I try looking at the 680k and 33k resistors.
These are in series to give 713k, but in fact we really need 710k........705k is too low and you only get sine, same case for 720k.
Unfortunately that 710k also depends on other parts being accurate to their declared value.
Andrew suggest replacing the 33k with 30k, then try 27k.
I removed the 33K resistor put in a 50k trimpot and tried to dial in the action, cos it probably won't be exactly 710k.
Have your panel pots at about 5-6 when doing this.
