Blingtron's Circuit Design Tutorial can be used by anyone (not just Engineers) and can be auctioned or traded.

Blingtron's Circuit Design Tutorial will also act as one of the reagents for  Reaves Module: Bling Mode, one of the modules that can upgrade  Reaves Battery.

Jewelcrafting has a similar item -  JewelCraft. JewelCraft is also consumable and starts a Bejeweled-like minigame. It has an associated achievement:  Hot Swapper.
