In her new Instructables, BECKY STERN illustrates how to add a voice control feature  to an vintage lamp using ESP8266 and Amazon Echo/Alexa.

To control the AC portion of the circuit, I’m using a Power Relay FeatherWing– just interrupt the hot lamp wire and plug the stripped ends into the Normally Open and Common screw terminals. Remember, if you don’t know AC, find someone who does to supervise. My lamp had a switch along the cord, so I just removed it and used the wire that the switch had been controlling.
