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 them 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

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
