Two Way Telegraph with Analog Feedback Servos

A fun way to communicate quietly (and wirelessly) within the same household or long distance to let someone know you’re thinking of them. These modern telegraphs use a combination of analog feedback servos and capacitive touch to create a two-way communication system. The emoji-clad dial is inspired by a ship’s mast. - Adafruit Learning System

cloudSmoker - BBQ Temperature Monitor

This is the last newsletter of summer, so we’ll include one last BBQ project. The cloudSmoker is a DIY temperature monitor for BBQ grills that can display time graphs of two temperature probes (pit and internal meat temperatures) and push notification alerts to a smartphone for when the meat is ready. -GitHub

E-Paper Price Tag Grid

E-Paper price tags are becoming ubiquitous at big-box stores in Europe (with slow adoption in the United States). After the tags were reverse-engineered, Aaron purchased a couple hundred of the tags and built them into a grid. Each display is controlled over ZigBee from a host PC. - YouTube

Using AWS IoT with the ESP8266

Brian took a deep dive to get AWS IoT working with his ESP8266 development board. This guide “should be treated like a recipe” and includes reproducible steps for using this board with the AWS IoT platform. - NetNinja

Modular Control System for a Garden Pond

Poseidon is a modular system for a garden pond. Leveraging a TICK stack (Telegraf, Influxdb, Chronograf, and Kapacitor), the system can control a fish feeder, water tap, the pond controller, and monitor the overall water quality. There’s also a web app to interact with the pond. - GitHub

MiniHelmetTracker - NFL Standings Tracker

As we proceed into American Football season in the States, Simon Schoar published their real-time NFL standings table robot. The MiniHelmetTracker “retrieves standings data - close to real-time - via WiFi and sorts mini helmets by the league, conference, division, and playoffs.” -schoar

CircuitPython on ESP32

The ESP32 is a great and very popular processor used on lots of development boards. However, its lack of native USB has kept it from getting a CircuitPython build… Until now! A new web workflow feature being added to CircuitPython 8 has brought the ESP32 back to the scene. This guide gets you started with CircuitPython on the ESP32. - Adafruit Learning System

The Engineer’s Guide to Matter

Ovyl has an excellent blog post up that cuts through the marketing details about the Matter IoT protocol and provides only the technical details. - ovyl

Azure Embedded Wireless Framework

Microsoft published information about their Azure Embedded Wireless Framework to GitHub. This is “a framework for writing applications and controlling wireless network adapters (cellular, WiFi, …) while abstracting a driver interface for hardware vendors to plug-in modules with self-developed drivers.” We’re all for abstracting driver interfaces! -Adafruit Blog

Support Adafruit

Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!). For those who want to get a project off the ground without programming - Adafruit IO offers a No-Code interface for building IoT electronics projects using WipperSnapper, our open-source IoT firmware. Support Adafruit’s open-source development by subscribing to Adafruit IO Plus, the upgraded, all-systems-go version of the Adafruit IO service.
