An automated electric grid powered by a Raspberry Pi 4, which is controlled by a hybrid smart contract using Chainlink Keepers to automate turning off LEDs for electric bill expirations [with sound alerts using Half Life's VOX (Black Mesa Announcement System).
Chainlink API/pricefeeds are used to get real world electric rate API data from the National Renewable Energy Laboratory and convert it in terms of MATIC/USD on Polygon.
Bonus project: Chainlink VRFv2 lightshow, with events logged on zkSync with 1 WEI deposits.
