A few things did catch my eye - Riedel Performer intercom system offer both a complete digital intercom infrastructure with the ability for endusers to upgrade via their current analog type systems. Whilst the ability to interface with various systems into big master system is not a new concept, the ability to link various systems via AES digital interface allows for some interesting transport and communications concepts that I'm keen to explore for some of my future projects.
I managed to spot a DeSisti LED fresnel - looking very much like an ordinary fresnel, but with sporting a high density LED panel, the fresnel consumes around 130 watts and has the output close to a 600 watt incandescent fresnel. It does not do colour changing like the Selecon PL3 but rather acts very much like a conventional fresnel, with very much reduced heat and no colour fringing. While light output and price continue to be the main issues, I would expect this issues to be sorted in the coming years with higher output offerings at much reduced pricing.
I found a quiet fan solution for the noisy fans that reside in equipment racks. Middle Atlantic Products have the UQFP ultra quiet fan series that have sensors that regulate the fan speed in the rack. There are various physical configurations and monitoring options available for these fans, including the currently in-vogue blue glowing LEDs.
