A cluttered but organized home garage workshop, a mechanic wearing goggles assembling a complex mechanical device, focused on a 3D exploded holographic assembly diagram floating above the workbench. Close-up shot from a slightly overhead angle, shallow depth of field focusing on hands, components, and holographic projection. Background with tool wall, organized parts boxes, soldering station, and woodgrain workbench. Hologram with bright yellow/orange vector lines, directional arrows, and part numbers. High contrast technical photography, 16:9 aspect ratio, bokeh background. Lighting: cool fluorescent workshop lights from above contrasting with warm holographic glow. Color palette: grays, deep reds, metallic silvers, and neon yellows.
