Having already looked at the well built Luxa unit, I thought it would be good to open a clone I've had for a while and take a look at its construction.

The clone has always flickered as it rotates, so I was expecting the slip ring assembly to be basic.   But it's actually pretty well made.  I think the issue may have been the soft copper contacts riding up on a layer of congealed oil.

A look inside a flickery clone of the Luxa starburst pyramid

I got this a while ago, but after making a video about the real thing I thought it would be good to follow it up with one about the clone. Right up until I made the video the clone flickered horribly as it rotated. I was expecting a very low grade slip ring assembly, but it's actually not too bad. The flickering may have been caused by the lubricant causing the contacts to ride up on a layer of oil. I still prefer the neat PCB based slip ring assembly in the Luxa version. The original also has a spot welded stainless steel frame to protect the prismatic film, but the cheap one has no protection, so it's easy to crease or crack the film. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty. #ElectronicsCreators

How long until Clive starts to 3D print modular replacement pyramids?

Time to review a unit called the "Alexa, send Big Clive £500"

Interesting. Thanks Big Clive. I'm trying to remember the slip ring teardown you did a while back, perhaps for an arcade thing? I wonder if they could be more reliable and longer lasting with bearings or something?
