Our site and the GGreg20_V3 DIY Geiger counter product are referenced by the author of the book Francesco Riggi, published by Springer in April 2024 under the title Educational and Amateur Geiger Counter Experiments.
We have previously written about how to calculate the coefficients for the SBM20 tube and the J305, tube that come with our Geiger counter module GGreg20_V3 for DIY / IoT…
November 06, 2023, Kyiv, Ukraine. Dear users, customers and partners! We are pleased to announce that with the launch of Etsy Payments service in Ukraine, we immediately opened our own…
