I Built My Own Ambilight for Under ₹1k, on the Same ESP32 That Runs My AI Desk Pet

TLDR: I wrapped 102 LEDs around my monitor and drove them from a single ESP32 running firmware I wrote myself. The strip cost ₹449. The whole build came in under ₹1,000. The same ESP32 also runs Dexi,

IR Remote Protocols Explained: NEC, RC-5 and IrDA for Makers

Pointing a remote at a TV just works, with no pairing screen and no password. That is the quiet advantage of infrared: the beam is directional and walls block it, so a neighbor's phone cannot snoop on

Arduino UNO Q Gets a Touch Library for Adafruit's 2.8in TFT Shield

A touchscreen shield that works on an Arduino Uno usually stops working the moment you move it to a newer board, because the SPI pins are not where the old code expects them. That is the exact trap th

Before connecting UART, keep three separate records

A supply rating belongs in the power section of an integration note. It does not tell you what can be connected to TX/RX, or how received bytes should become a distance. We are the ERDILRF technical r

Test a UART rangefinder parser before connecting hardware

A frame can pass its checksum and still turn into a distance that is wrong by a factor of ten. The missing piece is often the exact model's unit, rather than the serial transport. We feed the same syn
