JARVIS RECOMMENDS

Does Your Dinosaur Growl?

It will if you buy this unused take-out sound device and speaker. Includes a printed circuit board and a 2” 1/4W speaker mounted inside a 2-1/4” square x 1-1/16” gray plastic box. Includes a (3) “AA” battery box (empty) and power switch on one pair of leads, and a photocell in a brass tube on another because it’s motion sensitive. The sound is officially a dinosaur growl, although some folks here maintain it is quite distinctly a dino belch. A dyspeptic dinosaur is an angry dinosaur, we always say, so it’s a fine line. Check out our Facebook post to hear it in action.

This Thing’s Got A Pulse

Call it the Heart of a Doll, because that’s what it was, once upon a toy store. Today it’s a red, heart-shaped plastic thingy, 2-1/2" wide x 7/8" thick, with a smaller heart-shaped button on top. And yeah, it’s a little creepy. Hold the button and it emits a soothing electronic heartbeat at a tad under 60bpm. Runs on (2) button cell batteries, included.
