Thanks! I guess this is what those old kits I had have evolved into. It's too bad these don't work with Macs, but I saw one that mentioned a smartphone app interface. Will have to look into it further & see if that one'll work with an iPad. I know the 10-year-old lives in a Mac household, but maybe the 8-year-old has Windows available.
