Ooh, that's pretty! Great work there. We had some similar ideas in
the early stages of the project (converting it to a kit form and having
a build-at-home version), unfortunately we never had the time and
dedication to pull it through. BTW, is this your target brightness
or do you plan to use some higher-luminosity LEDs for next iterations?
Note that when you have many high-current LEDs connected to the same
PSU and shared bus and the lines are several meters long, you *may*
start hitting AC interference etc. issues if you didn't design your bus
properly; that happenned to us in the first version of ledbar. Just
something to keep in mind as you scale things up.
Making the cubes individually controlled and IOT is also an excellent
idea - it wasn't a good fit for ledbar, but two guys at our hackerspace
(TomSuch & da3m0n22) built essentially a platform for exactly that,
including an Android control app etc. Maybe you catch them in the space
tonight, or you can ask others for "MoodyLight" and there likely are
some prototypes lying around in the hackerspace. It might be nice to
join forces.
