Artifacts of the Wastelands offers GMs a grab-bag of oddities adventurers might find.
"Cloaks" serves as a catch-all for different kinds of outwear including stealth/camoflauge gear and environmental protection.
"Virtual Matter Projecters" are essentially "hard" holograms. Instead of simply creating a visual and/or auditory sensation, virtual matter is solid and can be interacted with just like any other object. Glove-like projectors create simple tools while more advanced projectors can create self-contained environments.
"Anti-Technology Weapons" are specifically designed to defeat other hi-tech toys and robots.
"Formulae" is easily the most adaptable section of the book. Essentially, they are a collection of "recipes" combining pre- and post-apocalypse technologies. Experimentation is encouraged.
