When a regular Cuckoo clock just is not exciting enough, adding an on demand remote button changes everything. In this project we built a two node wireless link using matched nRF24L01 plus PA plus LNA modules mounted on PTSolns NRF Shields. The transmitter detects a simple button press while the receiver drives a solid state relay that parallels the original clock button. A quick splice into the clock’s internal adjust switch lets the relay mimic a real press. The result is a fully wireless Cuckoo trigger that works from across the room and is surprisingly fun to use.
