MAKE contributing writer John Iovine has shared a number of his project builds on the pages of MAKE, but his specialty is Geiger counters. He’s been designing, making, and selling them for 15 years through his company, Images Scientific Instruments. In the latest issue of MAKE, Volume 29, John shares his expert step-by-step tutorial for making your own Geiger counter. And really, who doesn’t need a Geiger counter in their toolbox? There’s radiation in everyday household items, like Fiesta dishes, bananas, and kitty litter, making for interesting experimentation.
