CNX Software ☛ Arduino-programmable environmental and air quality sensor kit features ENS160 and BME280 sensors
Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display Module. It provides VOCs, eCO₂, temperature, humidity, and barometric pressure data in real time, making it ideal for Smart Home experiments, classroom projects, or hobby weather-station builds. The kit integrates a Sciosense ENS160 air-quality sensor and Bosch BME280 environmental sensor connected via Qwiic, which measures TVOCs, eCO₂, temperature, humidity, and pressure with an on-device AQI indicator.

Hackaday ☛ Wear This RISC V, RPN Calculator Watch For Maximum Nerd Cred
Once upon a time, owning a calculator watch was the epitome of cool. Well, for a very specific subset of the population with our own definition of “cool” anyway. The only thing cooler than wearing a calculator watch? Making a calculator watch, of course! If you do it as part of developing your own SDK for a popular RISC V microcontroller, all the better. That’s what [Miroslav Nemecek] did with his Antcalc watch, which is one of the demo projects for the CH32Lib SDK, which is currently under development at version 0.35 as this is written.
