The crusty copper is trying to get some data to flow using Actrix’s FreeTime. 9 Gig in a week is not bad, given 2 hours of freedom a day.

The Spartan-3 platform was the industry’s first 90nm FPGA, delivering more functionality and bandwidth per dollar than was previously possible, setting new standards in the programmable logic industry. The Spartan-3E platform builds on the success of the earlier Spartan-3 platform by adding new features that improve system performance and reduce the cost of configuration. Because of their exceptionally low cost, Spartan-3 generation FPGAs are ideally suited to a wide range of consumer electronics applications, including broadband access, home networking, display/projection, and digital television equipment.

Redwood Audio Amplifier for Bellaphone Speakers

I collaborated with Jordan Waraksa on a project that is currently on display at the Haggerty Museum of Art. He sculpted a pair of wooden acoustic horns called Bellaphone 5 & 6 out of walnut. Each horn rests on a redwood base that houses a small speaker.

I developed and built the electronics for the horn’s amplifier, whose chassis Jordan also sculpted from redwood. Because the chassis is wood and has no vents (for aesthetics), electrical efficiency became a high priority in order to prevent overheating. I chose to use a Maxim 98400A class D amplifier driven by a high efficiency switching 15V DC power supply. I added a digital signal processing chip from Analog Devices to increase the bandwidth of the horn and smooth out its frequency response (i.e. to improve the audio fidelity).
