BLEG: My earlier blog posts on electronics projects for kids produced this email: “Hubby is totally sold on the Snap Circuit toy for our boys — and so we’re ordering it ‘from the grandparents.’ I’ve been browsing Amazon for a book to go along with it to explain concepts that will come up in their play. . . any recommendations?” When i was a kid there was Elementary Electronics magazine, but I don’t know what’s out there now.
