A Nicely Crafted POV Lightsaber

We need to have a talk. As tough a pill as it is to swallow, we have to face that fact that some of the technology promised to us by Hollywood writers and prop makers just isn’t going to come true. We’re never going to have a flux capacitor, actual hoverboards aren’t a real thing, and nobody is going to have sword fights with laser beams.

But just because we can’t have real versions of these devices doesn’t mean we can’t make our own prop versions with a few value-added features, like this cool persistence-of-vision lightsaber. [Luni], better known around these parts as [Bitluni] and for his eponymous YouTube channel where he performs wizardry like turning an ESP32 into a software-defined television station, shows he’s no slouch at more mechanical builds either. The hardware is standard POV fare, with a gyro to sense the position of the lightsaber hilt and an ESP32 to run the long Neopixel strip in the blade. There’s also a LiPo pack and a biggish DC-DC converter; the latter contributes mightily to the look of the prop, with its large heatsinks that stick out from the end of the aluminum tubing hilt. There’s also a small speaker and amp for the requisite sound effects on startup and shutdown, and the position-sensitive thrumming is a nice touch too. Check out the POV action in the video below.

What’s that you say? You recall seeing a real lightsaber here before? Well, sort of, but that’s pushing things a bit. Or perhaps you’ve got this more destructive version in mind.

An Alien-Themed… Cuckoo Clock?

If you are a follower of the sci-fi horror film genre then it is likely that you will be familiar with the Alien series of movies. Images of Sigourney Weaver bearing a significant amount of firepower, or of John Hurt’s chest being rent asunder by an emerging creature will be brought to mind, it’s one of those franchises which seems to have entered the public consciousness.

With the release of another movie in the series fast approaching, [Keith Elliott] resolved to mark the occasion with his own Alien themed tribute. What, you might ponder, could he choose? Surely there must be plenty of iconic moments in the films that could provide fertile ground for a tribute project!

So  presumably after a significant period of reflection, he’s built an Alien themed cuckoo clock. Something of an off-the-wall choice, you might say, but he persevered with it. The main body of the clock is the torso and head of an unfortunate human crew member, the face of the clock is formed by an alien facehugger on his face, and the cuckoo is not a bird in the manner of the Alpine originals, but a chest-bursting alien that issues forth from the torso.

There is a video, which we’ve posted below. Perhaps the chestburster action needs a little more spontaneity and to be a little less rhythmic, but we’ll leave it to you to decide whether it is inspired or merely kitsch.
