He began to work. He built a cradle for the core and wired it to an old generator with spare copper and a coffee can. Each morning the crack in the foam widened a little. With each widening, the core pulsed quicker. Devfus salvaged sensors from a rusted photocopier and fashioned a reader from a discarded phone screen. The device responded not to code but to touch—light grazes, the breath of fingers, the pressure of a pause. When he held the reader near the crack, the foam peeled away in flakes, and the core’s sigil glowed like a bruise beneath his palms.
Cut out a 4-inch square around the crack. Remove every piece. Clean the substrate with acetone (test a small area first—acetone melts some plastics). Re-apply the foam using the steps above.
