Stuart “Mr. Retro” Sandler built a super retro robot from plans found in a 57-year-old copy of Boys Life he’d purchased from eBay. Stuart had heard about the robot as a teenager and wrote to the magazine for the copy of the plans. They sent him a photocopy but left out a couple of key details, which he learned about later after he’d bought the actual magazine. Here’s a video of the robot in action.
