Sometimes it’s about adding some sci-fi drama to your everyday gadgets. That’s exactly what this amazing Star Trek Electronic Door Chime claims to do. You just have to mount it beside your door and whenever someone passes by your door, it will alert you. You can choose to either open the door or go for a red alert alarm. But the catchy part here is that you’ll get to know who’s at the door even before they realize you do. The chime has been inspired from the communicator panels on The Original Series of Star Trek and is definitely a must have for those geeks who have admired Star Trek for all these years.
