Server Problems

10th April 2007

Due to a recent hardware failure we have had to rebild the site from backups. This means that a few links on the site are broken. We will get the rest of the site and the e-commerce store back online in the next couple of days. The service database aplication will return after a major update to its software in the coming month. Apologies for this but the failure was out of our control. We have now put systems in place to ensure it does not happen again.

Rugby World Cup

14th October 2003

bcd was recently commissioned by Namagi Systems - manufacturers of on-screen scoring software - to produce a large number of interface cables.  These cables were used to connect their systems to the internal venue wiring used in all the World Cup stadiums. All cable was delivered within the short turn around (one week) including sourcing components, manufacturing custom parts and testing .

City (no longer) Live

24th April 2003

Well as if Sydney has enough good live venues, now there is the closing of City Live at Fox Studios. A Baz Luhrmann designed nightclub, it never really lived up to its potential due to a draconian license restrictions.

Massive service

14th April 2003

On the day of the Sydney gig, we got a phone call at 10am from the Lighting Designer for the Massive Attack '100th window' tour requesting a service call on a Coemar Super Cyc 2.4. With none of these fixtures in the country it meant that there was no option other than to repair the one brought from the UK with the band.

Arriving shortly after 11am, after tracking down a wiring diagram from Italy, we set to work on the fixture. A few hours later they were back in business with the fixture back in the rig and the client very happy .

The Super Cycs are used to spectacular effect during the show with four used as floor mounted backlight, with an additional four used as backlight. They are impressive enough when stationary, but when you see 2400w of CMY colour changer fang through 360° it is a truly amazing sight.
