Geiger–Müller counter that can work with Arduino or (almost) any evaluation board

Electronics News Updates / By

The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains three (instead of one as usually) soviet STS-5 lamps. This is important for measurements of natural sources of (low) radiation like soil, rocks (an article about my trip with Geiger–Müller counter on Śnieżka mountain). Principle of

Pozyx: accurate indoor positioning for Arduino

Electronics News Updates / By

What is Pozyx? Pozyx is the first affordable and easy-to-use hardware solution that provides accurate indoor (and outdoor) positioning and motion information for Arduino. In order to achieve a positioning accuracy of a few centimeters, the pozyx system relies on a novel wireless radio technology called ultra-wideband (UWB). The accuracy achieved with this ultra-wideband technology
