Arm Cannon Calibration

I came back inside as evening fell, determined to assemble the forearm projector rig you suggested. On the coffee table, I found an empty cardboard thread spool and slipped it snugly over my left forearm. Next, I nested the miniature red LED torch right inside the cylinder core. To make sure the output stayed completely controlled and safe, I fitted two layers of translucent paper over the opening like an adjustable lens cap. Bracing against the wooden table, I clicked the tail switch with my right glove. A perfectly soft, contained crimson ring projected against an upright coaster without any heat or glare. It feels steady and ready.
