Turning an ESP8266 Programmer Into an ESP Earring

You might not look at an ESP8266 programmer and think “wearable Ouija board planchette earring”, but Alex Glow did. Aside from having an Art Nouveau-Esque silkscreen, this programming jig is both functional and wearable. – Hackster.io

Showcasing the Contentful blog with E-Ink, CircuitPython, and IoT

Inspired by the “Moveable Type” art installation by Mark Hansen and Ben Rubin, Shy Ruparel utilized an Adafruit MagTag to build an e-Ink blog viewer for displaying the latest articles from Contentful’s blog – dev.to

Quickstart IoT – Raspberry Pi Pico RP2040 with WiFi

The $4 Raspberry Pi Pico is quickly becoming a popular development board due to its price, clock speed, and available GPIO. Easily add WiFi-connectivity to your RP2040 projects by following this new guide. – Adafruit Learning System

e-Ink COVID Vaccination Tracker

Vaccinations for COVID are well underway in most countries, and what better way to keep track of vaccinations for your country or region than with a battery-powered, refrigerator magnet that’s connected to the internet. – Adafruit Learning System

Shadow Box Internet Clock

An internet-enabled shadow box project that tracks the movement of the sun using NeoPixels. Check out the guide for the complete video, the lights add gorgeous colorful depth to your artwork. – Adafruit Learning System

Connecting LoRa Sensors to Google Home Assistant with Node-RED

Ben built a Node-RED workflow for sending data from LoRa connected temperature nodes to Google Assistant. – Hardill.me.uk

Remote light switch with Blynk, Node-RED, and MQTT

Using an ESP8266, a push-button, and two AA batteries, Mike built a physical switch to replace a voice-controlled switch. They built a new NODE-RED workflow to integrate their previous workflow with the light switch. – whatimadetoday
