Pretty inefficient. Too many rings getting not enough solution or fan time and also too close together making clumps of bubbles. There’s a reason the commercial units use way less rings and produce far more bubbles. I have a 3D printer. It’s not worth my time and effort to print this design v.s spending $79 on eBay…

What we need is a green technology based on a highly popular recreational technology.

Indeed. I expect the level of dedication you’ll get from your average drug runner is figuring out how to fly a DJI Phantom, really really slowly, in headless mode to the middle of a recreation area. Whereas I could probably zip my Lumenier 250, in rate mode, across the entire campus in a couple of seconds. You can’t…

This only applies to multi rotors. And even then, for some flight controllers, in Rate Mode you can turn off or at least turn down the gains on gyro input.

Conspiracy theorists will only find other ways to satisfy their confirmation bias. In this case, wherever the plane landed (secretly), someone chopped up some parts and tossed them in the sea so that the authorities would close the case and stop looking for passenger.

Is that a composite image, single but wide-angle and corrected, or is it really far enough out to frame the whole planet without distortion?

So that’s the light they are talking about in Poltergeist. That room goes to the far side of the sun! Who knew!

Definitely a bad idea, but there were no electronics in the burning man. It was being towed by a drone on a long cable. But that drone could have had some sort of failure, so yes, still a bad idea. That said, the video gives no real indication of any of the failsafes or safety precautions they took, of which I’m sure…

So the Boa does a sleeper hold, not a choke hold. Who knew!

If you shoot down drones, please consider doing so when it’s right over your own head, or your car. This is a relatively small LiPo battery. DSLR capable octocopter drone LiPos can be the size of house bricks.

It’s not just IF, but WHEN. Who knows what has been and gone already...

As a kid I used to imagine the end of the universe was like everything being inside a big sphere. Travel in any direction long enough, and you’d hit that “wall”.

*sigh* See my other reply to the same comment....

I’m 99.9% certain it did not state the “without the crossover in the middle” earlier. They do actually correct stories when people point out things like that. Even if it was in there, like GreenLED said, the title is misleading. But I guess figure 8 is more click-worthy than biconcave stadium, which would confuse…

I’m not seeing a figure eight being traveled by the cars. It seems from the rendering and the inside shots that they travel more of a biconcave stadium shape. (In lay terms, a pill shape squished in the middle). I don’t see the cars crossing over to actually run a figure 8. The paths don’t cross, only the gold…

The expanding areas make me think of growing fat deposits on a side of bacon.

The evolution of morphing. Remember when that first came out?

Just give me the PES1 already...

Great in theory, fails in practice when you are stopped with a message like “Your password must contain at least one number, one punctuation mark and one upper-case letter.”
