Thought I would share my v.1 device built using your board, some code you provided, and a few additions, and hacks
I will try to get pixs up in this thread a bit later on…
In the meantime, here is a video shot via an iphone so the sound quality doesn’t really do it justice, this thing is loud and distinct out to 120ft
Very nice build! I like the case. If there are any technical details you can share about how you are driving the speaker, please let us know. A lot of people would like to drive a loud speaker.
