"We won't be doing that at the library, but awesome," said librarian Lori Easterwood, who will be integrating Maker Camp into her summer program at the Sacramento Public Library.
Camper Zack, 13, is going to take part in the program for a second summer.
Inspired by last year, he's been working on a remote-operated vehicle that goes underwater and has a mounted camera. He hopes to finish it in time for his family's summer vacation so he can drop it into Clear Lake in north-central California.
"I want to see if there are any catfish down there," he said.
Wherever the campers are tuning in from, participation is key.
"This is definitely not computer camp. We don't want kids sitting in front of their computer," said Michelle Hlubinka, the Maker Camp education lead. "I'm always so sad about the kids spending their summer looking at a screen. We want them to go outside!"
