LakeShark firmware turns LilyGO T-Display P4 into a handheld ESP32-P4 SDR scanner
AI summary
LakeShark là firmware open-source của Samuel Reynolds biến LilyGO T-Display P4 - module ESP32-P4 - thành scanner SDR di động. Tác phẩm tận dụng khả năng xử lý 400MHz và floating-point unit của ESP32-P4 để xử lý tín hiệu RF. Hệ quả là thiết bị có thể quét tần số từ 24MHz đến 6GHz với độ phân giải cao. Điều đáng học là việc tối ưu hóa resource-limited device cho ứng dụng signal processing phức tạp. Code nguồn có thể tham khảo để hiểu cách implement real-time FFT trên embedded platform.
AI summaries can be wrong. Read the original before relying on anything important.

Saving A Vintage High-Voltage Power Supply From The Scrap Heap
A Fluke Model 407 high-voltage power supply gets rescued from the scrap heap and diagnosed on video. Mr Carlson powers it up safely using an isolated transformer and a current-limited variac, avoiding the risk of full power on old components. The vacuum-tube-and-circuit-board unit shows no visible damage but its output misbehaves. Using the original schematics, he traces the fault to a single faulty capacitor in the feedback loop that keeps output voltage constant.
