The uBeam FAQ

<< < (287/396) > >>

EEVblog:
The transducers. Note the acoustically transparent white visual alignment squares.

coppice:
So, what are we looking at here? From the white squares I assume there are 2 receiver arrays. From the different colours I assume they are of 2 types. Is the rectangular array the transmitter? What is the white thing at the top right?

Kean:
Looks like someone had fun with side cutters removing the little grilles on a bunch of Murata transducers to make them look different

mikeselectricstuff:
I wonder if that's a real eval kit, or just some stuff they threw in a box to make it look like they have an eval kit.

EEVblog:
Note that the left hand transducer array has white marks on the side of each one, likely some sort of production test pass marking.
Doesn't make sense if they are COTS, but if they are the uBeam ones, the large COTS-like plastic package doesn't makes sense either.
