After a lot of work over the past week, I've got the fundamental instructions for building and operating an RTI dome system. done and posted There's a few sections that I'd like to add (more on this shortly). But in the long run, there are a few things I'd like to do with the system, both to make it easier to assemble and also to add extra capabilities. In the unlikely event that I win a residency at the SupplyFrame Design Lab, these would be first on my list. More likely, I'll have to find the spare time to work on some of them at some unspecified time in the future.

1. Design a PCB board. Man, this would make assembly so much easier, cut down significantly on the part count, and reduce the possibility of error.
2. Enclosures. With a PCB board designed, I could also design laser-cut and/or 3D-printed enclosures it could fit in. That would cut down quite a bit on assembly time.
3. Extra outputs. A PCB board would free up enough space to add more CAT4101 output channels. These could double the maximum LED count from 64 to 128. Alternatively, they could double the output current from 1 to 2 amps for 64 LEDs, which would be great for larger domes. Cree does make LEDs that can handle that current.
4. A mega-dome. The current design has enough output power to drive a dome at least a meter in diameter, and possibly a bit larger. The optimum artifact size for a dome, though, is roughly the radius, so that's a half-meter for a meter dome. There are many objects that could benefit from a larger dome size, like paintings and fossils. I have an idea for a simple addition to the current control electronics that could drive a "mega-dome", with a diameter of up to 4-5 meters capable of imaging objects up to 2.5 meters in size.
5. Multi-spectral. People have reported useful results with RTI in the IR and UV spectral ranges, so I'd like to try that.
6. Super-automated. In principle, you could build a fully-computerized system that could photograph and process objects without human intervention. Robot arms to place objects, software to automatically process photo datasets when they're done. We have the technology ...
