Open Source and programmable
The Soundlazer has a built in programming port that interfaces with Analog Device’s Sigma Studio DSP developing environment. An easy to use graphical interface allow you to create your own custom filters, compressors and other sound shaping algorithms to improve or change the characteristics of the sound beam any way you like. The Soundlazer is [...]
Some nice color choices for the case
A color hasn’t been decided on for the production model but the red is looking pretty good.
Completed Soundlazer
After months of design and testing, the Soundlazer is now finished and ready for manufacturing.
Designing the enclosure
Designing the case turned out to be as difficult as the circuit itself. A modern, “Apple” style case was the goal but with a retro feel. A classic microphone offered the inspiration for this design project. Classic Ribbon Microphone The high frequencies emitted by the Soundlazer presented some problems in the case design. [...]
Circuit Board Layout
The SoundLazer uses very small surface mounted components There is a whole lot of technology crammed into a small space in the Soundlazer. Many of the surface mount components are size 0402 which is going to make prototyping this board a bit tricky. Time to get out the microscope and tweezers for this soldering [...]
The Schematic
The design of the Soundlazer circuitry took place over the last year with lots of testing and some experimentation. Many of the results have been posted throughout this website. A line level, stereo headphone jack similar to the one found on most computers and iPods connects the ADAU1701 Digital Signal Processor to the outside word. [...]
