TL;DR: A 2048-code RC5 matrix means only 2 k signals cover most TVs, and “IR rays are invisible to the human eye” [Elektroda, RADKON, post #3303710] Build an IR "sniper" with a universal remote, photodiode, and binocular-mounted IR LED to silence noisy gear up to ~30 m away. Why it matters: This FAQ helps apartment dwellers quietly disable or control neighbours’ loud TVs or stereos without confrontation.
• Typical IR LED wavelength: 940 nm ± 20 nm [Osram Data, 2023] • RC5 protocol: 32 device addresses × 64 commands = 2048 codes [Elektroda, Marcin1326, post #3307267] • DIY range with 1 W IR LED & optics: 20–40 m line-of-sight [Elektroda, kiler129, post #3302821] • Salvageable IR laser diode: found in CD-RW drives, output ≈ 30 mW [Elektroda, kiler129, post #3303773] • Entry-level universal remote price: PLN 15 (~€3) [Elektroda, arek14, post #3319959]
