A Keyboard for Anything, Without a Keyboard
There are many solutions for remote control keyboards, be they Bluetooth, infrared, or whatever else. Often they leave much to be desired, and come with distinctly underwhelming physical buttons. [konkop] has a solution to these woes we’ve not seen before, turning an ESP32-S3 into a USB HID keyboard with a web interface for typing and some physical keyboard macro buttons. Instead of typing on the thing, you connect to it via WiFi using your phone, tablet, or computer, and type into a web browser. Your typing is then relayed to the USB HID interface.
The full hardware and software for the design is in the GitHub repository. The macro buttons use Cherry MX keys, and are mapped by default to the common control sequences that most of us would find useful. The software uses Visual Studio Code, and PlatformIO.
We like this project, because it solves something we’ve all encountered at one time or another, and it does so in a novel way. Yes, typing on a smartphone screen can be just as annoying as doing so with a fiddly rubber keyboard, but at least many of us already have our smartphones to hand. Previous plug-in keyboard dongles haven’t reached this ease of use.

A Simple Desktop Pomodoro Timer
Pomodoro timers are a simple productivity tool. They help you work in dedicated chunks of time, usually 25 minutes in a sitting, before taking a short break and then beginning again. [Clovis Fritzen] built just such a timer of his own, and added a few bonus features to fill out its functionality.
The timer is based around the popular ESP32-S2 microcontroller, which has the benefit of onboard WiFi connectivity. This allows the project to query the Internet for things like time and date updates via NTP, as well as weather conditions, and the value of the Brazilian Real versus the American dollar. The microcontroller is paired with an SHT21 sensor for displaying temperature and humidity in the immediate environment, and an e-paper display for showing timer status and other relevant information. A button on top of the device allows cycling between 15, 30, 45, and 60 minute Pomodoro cycles, and there’s a buzzer to audibly call time. It’s all wrapped up in a cardboard housing that somehow pairs rather nicely with the e-paper display aesthetic.
If Pomodoro is your chosen method of productivity hacking, a project like this could suit you very well. We’ve featured a few similar builds before, too.

Venerdì sciopero internazionale dei porti. è la prima mobilitazione unitaria di portuali europei e mediterranei nella storia

“I portuali non lavorano per la guerra“. E’ con queste parole che i sindacati di Enedep di Grecia, Lab dei Paesi Baschi, Liman-Is di Turchia, ODT del Marocco e USB in Italia hanno
