Microcontroller-based Star Trek TNG operational display

Darian Johnson built a Star Trek: The Next Generation inspired terminal that displays the weather, indoor temperature, volatile organic compound strength, fitness information, and more. This is one of the nicest-looking personal smart-terminals we’ve seen and even features a resistor color-code chart and a current measurement tool. - HackADay

Fermenters Friend – Home Brewing Temperature Monitor

After making a brew, one needs to “let it ferment, trying to control the temperature range from an ideal of around 18-22 C”. They used a Cheeseboard ESP8266 development board to monitor the brew’s temperature as it ferments and display it on a LCD and online. - Adafruit

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.
