Cloud harp on its way to Pittsburgh

The cloud harp woke up again for an upcoming performance in Pittsburgh. As it's due to stay outside for a long period, and why not, under the rain, we've covered it with several layers of polyurethane varnish (photo 1).
A huge truck is required for transportation (photo 2). Once installed, it will stream over the Web music created off the shape of clouds.

First take off


We inflated the cubic balloon that's inside the wood structure, and "cut" the umbilical cord of our baby, I mean the RS232 cable that connected the onboard Linux computer to our ground-station laptop (see picture: cable hanging down). We were all worried because:
1) we didn't know how much to inflate it
2) we didn't know if it'd take off at all
3) we weren't 100% sure if the balloon was big enough to contain sufficient helium for take off, and compensate for structure+mecatronics weight
But, when we saw it majestically and quietly take off, we immediately turned off the helium valve and put the stopper on the balloon. Waow. Really: WAOW!
Look...
