The resource thing always gets me. More ideas of things like dyson sphere's. Where does the material from them come from?

Probably from deconstructing the solar system's asteroids and planets. I imagine a Dyson sphere would be less structurally sound and harder to get right – due to gravitational forces on the material – than a Dyson swarm or matryoshka brain. The latter made of independent satellites orbiting the sun and collecting light from concentric orbits at various distances.
