Build-order checklist

  • Pic 5, base closingMount Nano, power bank, master switch, 470Ω + 1000µF in the crawlspace. Leave the 3-wire chain head + risers poking up.
  • Pic 8–9, GF wallsSolder P0–P3 (porch, entry, deck) through pre-drilled holes as walls seat.
  • Pic 10, chimney baseDrop P4 flicker into the hearth.
