We have currently built two standalone USB powered DIY projects and we will continue to build more. Powering all of them is going to be a challenge and thus, I decided to build this USB power hub that can be used to power passive devices. You can also use the split, microUSB cables to connect up to 8 devices in total. The hub has a wide input voltage range and is small enough to be tucked away beneath your desk.

IFTTT has been around for a while and it can be used to easily automate different services and products without having to program a lot. A lot has changed over the years and in this video, we take a quick look at getting started with IFTTT. We also configure the webhooks service and use an ESP8266 based WeMos D1 mini board as a trigger. As an example, we use this to send an email and app notification when a button is pressed and also when motion is detected in a room.

As a follow up to the first DIY project (Room Thermometer), we write a sketch that communicates with an online weather service (OpenWeatherMap) which provides the weather data for just about any city. We use this information to display the temperature, humidity and weather conditions to an OLED module. BONUS: We also talk to the TeamTrees website and obtain the live tree count as an example to talk to webservers that do not provide a JSON response.

There are many DIY subscriber counter videos that use the ESP32 along with the Arduino YouTubeAPI library but this uses ArduinoJson 5 and was not compatible with the latest Arduino IDE and Nano 33 IoT board. I decided to communicate with the webserver directly and obtain the subscriber count by parsing the JSON data.
