Miles away from that special someone, or just social distancing? Want to let them know you're thinking of them? You can set these internet-connected faux-neon lamps to beating from your phone or computer, any time, from anywhere. With a click of an app you can start someone's heart pulsing wherever they are. And by linking additional lamps they can return the favor at the push of a button.
The brains of this heart is a Wemos mini ESP8266 and transistor driver which control LED lamps in a variety of shapes and colors, running through Adafruit's IO service. Add a 3D printed base with a pushbutton and you're all set. Detailed instructions on how to build your own at www.instructables.com/Internet-Neon-LED-Heart-Light/
