Following the rule of "awful dress rehearsal, flawless show," the show went well especially the technology pieces.

That said, there are some key lessons learned and places to improve upon for the next iteration:

1. Rechargeable batteries that do not require opening the enclosure. This was so time consuming for 12 tubes. The change to LiPo can lower the weight as well.
2. Moving to another soldered in or robust connector power source and connector. This was a key pain. The first point can probably resolve this.
3. Use a slow frequency sampling accelerometer to resolve the issue of which end is up. Requires a new driver, display improvement to handle orientation , and support feature in light design software (gosh, still need to upload here).
4. If the tube lost power or connection, it lost the time stamp and was stuck back in "bootloader" awaiting the synchronizing tone. Also if we wanted to rehearse from middle of a piece, the lighting was not available. Ability to time synchonize to the rest of the system even if not from the beginning would be helpful.
5. Port light design software to an digital audio workstation plug-in model. Audacity allows for people to develop plugins using Nyquist(Lisp). This would allow each tube to be an "audio track" in the DAW and be able to play back things with the music immediately in both simulator and on-target.
6. Following from this, over the air tube update would be great to update the programs on each tube as need be. Once again another reason to not open the device. Even better: Use the DAW plug in to support OTA.
