Blueprints Requiring Circuits[] Market[] By purchasing this item you can directly exchange  30 for 1500 Circuits.—In-Game Description Beginning in Update 9.0 (2013-07-13) materials could be purchased directly from the market for  Platinum. Gathering Tips[] These are based on opinions and may not be 100% true. These should be viewed as advice for finding the materials until better facts are proven. Deploying a Titan Extractor on Venus or Ceres is an easy way to gather circuits. Tessera (Defense) on Venus. Dark Sector missions on Venus or Ceres. Trivia[] Bugs[] If a player uses all of their Argon Crystals in a recipe, Circuits will display the remaining time till decay. This is a visual bug and will not affect a player's remaining Circuits.
