 can contribute more.
But nevertheless, this was not a worthless project at all. Now I have a working radiation meter which I could use in various scientific experiments and projects (e.g how weather and season factors to background radiation levels). And as always with my projects, this is not the end. I can always add things and change or repair some. Fro example, I’m waiting for an additional switch to change between display modes, and a new display plate that has some better aligned screw holes.
One has to just continue experimenting and creating things so we can keep this world from ruining and to advance it. Even accidents like Chernobyl, Fukushima and countless others have contributed our science and society.
