Description: In this video we upgrade a basic doorbell to send notifications over WiFi. With some power harvesting no battery is required. An optional Node-RED server translates the signal and activates a visual notification remotely. This not only helps if the bell isn't audible but can also be use for hearing disabled people. Code and Noder-RED flow can be found here: github.com/bitluni/Doorbell Links to parts and tools (affiliate links): ESP8266 D1 Mini ($3.50): aliexpress.bitluni.net/d1mini Flexible RGB LED Matrix ($12.20): aliexpress.bitluni.net/flexRGB AC to DC PSU with Barrel Jack: aliexpress.bitluni.net/ACtoDCBarrel Small DC-DC Converter: aliexpress.bitluni.net/smallDC2DC Electrolytic Capacitors: aliexpress.bitluni.net/elco Zener Diode Set ($4): aliexpress.bitluni.net/zener Full Bridge Rectifiers: aliexpress.bitluni.net/fbr LED Projector ($72): aliexpress.bitluni.net/projector My camera and lens (4k 60fps): amazon.bitluni.net/gh5 Zoom H6 Audio Recorder: amazon.bitluni.net/h6 plz share :-) Tindie store: tindie.com/stores/bitluni Github Sponsors: github.com/sponsors/bitluni Patreon: patreon.com/bitluni Channel membership: youtube.com/channel/UCp_5PO66faM4dBFbFFBdPSQ/join Paypal: paypal.me/bitluni Dogecoin: DLhdK867hZCvuPqmpgviZqgfvUTdSiRfoU bitclout: bitclout.com/u/bitluni Twitter: @bitluni reddit: u/bitluni Discord: discord.gg/MT5RbJt Music: Jeremy Blake - Powerup!
