Well, my iPhone didn't do a good job of picking up the audio (or Youtube didn't)... but I can assure you this DMD is noisy!
Its that weird buzzing that changes depending on how much of the DMD is lit.
Wondering if there is a fix or if I need to buy a Vishay. Wanted to pop it off to look at the brand but I have to find some type of cylinder tool to get it off the white post things.
