d101 Sci-Fi Gadgets

I was looking for some "wondrous items" table for a sci-fi OSR campaign, but could not find any. There seems to be a pressing lack of d100 sci-fi treasures or post-apocalyptic loot tables. So I made such a table. :)

Here are d101 tools, gadgets and curios that your players can have fun with. They are fairly system-neutral, just replace Energy with whatever source of power your rules use. Note that while these items could work in any sci-fi setting, they are intended for a post-apocalyptic or gritty game where high tech is scarce. It's more interesting to find a single gadget in a lost bunker on the corpse of a survivor than to order a cartful of them on eBay.

This list contains no weapons, armour, implants or vehicles, as those will come in later posts.

This is exactly where you should find some gadgets.
From here.

d101 Gadgets

1. Superconductor spray: This can contains room-temperature superconductor nanopaint. Your science projects were never so easy!
