Technical Update Regarding Soundlazer
Now that many of you have received your reward levels, I wanted to give you some important information regarding setting up your Soundlazer. If you haven't received yours yet, keep an eye out in the mail for it because they are on the way. Obviously, International backers will have a longer wait as they travel further, clear customs, etc. 99% of all packages have shipped. Believe it or not, I still have a few people that didn't fill out their surveys or give me their address. If you are one of those remaining few, you only have a couple of more days until this project is officially closed.
Using Soundlazer for the first time
When you first open the box, with the switch set to middle position, connect your iPhone / iPod, etc and power plugged in, you may think the Soundlazer works like a regular speaker. If you move your head away from the beam, suddenly you will notice that the sound almost completely disappears. The effect is one of the most interesting aspects of parametric speakers and one I hope you guys will experiment with the most. Beam forming, horns and other tricks should produce some interesting results.
Try pointing the Soundlazer at a hard surface across the room and suddenly you hear the unique properties of ultrasonic waves.
Remember, if you don't have an audio source handy, just change the switch to the right position (test tone).
Firmware, case design files and other technical information can be found HERE
Note: Some people have noticed a low volume tone produced by the ultrasonic array. This is a result of the ultrasonic transducers “ringing” when they are in perfect tune. This tone is simply a subharmonic frequency of the 40KHz signal (20kHz, 10kHz, 5kHz, 2.5kHz, etc). To eliminate this tone follow the instructions on this Soundlazer Adjustment Post
Comments, Ideas, etc
Many of you have already contacted me and complimented the work I have done on this project. I appreciate all the kind remarks and I am leaving this post as the official publicly viewable one so that you guys can express your excitement, share ideas and simply leave a nice comment about Soundlazer. Please note, that I am asking for nice comments here. If you have any issues with shipments, etc, please email me directly using the Kickstart email contact system.
It has been very rewarding hearing all the nice compliments. Once again, thank you to everyone for supporting me.
I hope to see you guys again for my next project.
