I know some of you have been wondering what I have been up to with Soundlazer.
It's been a long road but I am happy to say, that the first boards for approval have come off the assembly line and everything has tested to work perfectly. I will be signing off on the production run and both blank and propagated boards should start arriving soon.
I have added a few features to the Soundlazer based on backer feedback. These include:
1) High / low power jumper for testing and extended listening.
2) Auto power off so that no ultrasonic energy is emitted unless there is an audio signal present.
3) Test tone output
4) Improved digital amplifier with more effiecint design.
Here is a picture of the final board.
I expect to receive the blank boards that backers ordered first so I will be sending out the surveys for those people very soon. Be sure to fill out all the information so I can get the boards to you quickly.
Thank you to everyone once again for backing the Soundlazer project.
