This is 'Ether' a Steampunk Spectrum Analyser display unit. Totally functional, there is a brass horn on the top that picks up ambient sound and then the electronics display on the 10 IN-13 tubes. The silver cylinder on the left contains a high gain microphone, with the brass horn acting as a mechanical amplifier. Together they are then sensitive enough to pick up regular conversation. Made out of an old Victorian brass bound writing slope, and an old industrial temperature gauge supplied by the client for me to fit into the design. The name 'Ether' comes from the gauge. I also added a full RGB lighting effect too, inside the curve of the glass on the front gauge. You can see a clip here of it running.
The Analyser display can be added into any clock or project, as well as a stand alone product called 'The Array'
