The Bop It memory toy has seen many iterations, always with neat triggers. It’s a fun toy, especially for those with a more tactile memory (I was always great at Bop It and terrible at Simon). But the thing is annoying as hell unless you’re the one playing it, so Instructables user jzzsxm added a headphone jack and speaker/headphone toggle switch. The build photos in the guide make it easy to perform this mod yourself. I recommend adding this feature even before you give this toy as a gift.
