PocketAdmin – Keystroke Injection Device
This is a keystroke injection device (also called badusb). It is similar to a well-known USB rubber ducky made by hak5, but has much extended functionality, lower price and is also completely open source. It looks and feels like an ordinary USB flash drive, but acts as a keyboard that...

Portable Fine Dust PM10 Analyzer with Large OLED Digits
In one of our previous articles, we built a DIY air quality monitor which was based on measuring the amount of Hydrocarbon concentration in the air using the BME680 VOC Whisker. While things work quite well using that method, there are several other parameters and air constituents which...
