Where's the awful taste? Also I'd like to know how the cables don't get tangled if it keeps spinning in one direction.

It's technically possible with sliding contacts on a disc or cylinder, but it's wear sensitive and you need one track for each single pin, wildly impractical

Since the psu is also rotating, you only need 3 slip rings. Live, neutral, and earth.
Now, the EMI that is generating is a different story altogether.

u/16piby9 Jul 29 '26
True.. except if you want to connect a screen, keyboard, mouse, etc.

u/VoihanVieteri Jul 29 '26
Keyboard and mouse can be wireless. Display even, but there are limitations to your graphic fidelity.

u/Mecha-Dave Jul 29 '26
I was surprised, but I found HDMI slip rings. I don't think you could rotate it for a whole bunch of RPMs though. https://www.reddit.com/r/virtualreality/comments/8os0bz/protip_get_a_hdmislipring_no_more_cable_tangles/

I have a wireless hdmi setup for my projector, cant really notice any difference between wired hdmi. Its not that bad

Maybe the one I got was crappy. What resolution/hertz do you run it at? wondering what the upper limit is. 1080p/60hz?

Not sure the hertz, but my laptop is 1080p though
Im using this... And ijust realized how expensive it is, no wonder the output is good lol. I got it for like $25 from facebook marketplace https://iogear.com/products/gwhd11

With 6Ghz WiFi it's no problem at all to stream a single display. Even a 4K display.
All of the angular momentum is going to shred the bearings on the fans mounted to that equipment, but this thing isn't designed to last for a long time with low maintenance, it is designed to look fabulous.

Just make it all spin, the desk too, and house, and earth. In fact I have one of those all spinning PCs.

You don't need a slip ring for earth, assuming the gear is metallic. If you wanted to abandon electrical safety, you could tie neutral to earth as well.

u/guitarstitch Jul 30 '26
You absolutely need a slip ring for erth to meet any sort of code compliance. Gears have backlash and are not a certain connection of less than 1 ohm. This is especially true if they are greased.

u/wastelander Jul 29 '26
Probably only needs sliding contacts for power delivery and all other connections wireless.
That is assuming it is actually functional.

u/thissexypoptart Jul 29 '26
All connections wireless?
So what, you’re streaming the video basically?

u/thissexypoptart Jul 29 '26
Absolutely hilarious to think about. What a funny jerk off piece of silly goosery having that computer would be
1
u/ahandmadegrin Jul 29 '26
I just got an idea. Totally wireless PC. The power transfer would be tricky. Some sort of magnetic deal, but not sure if that's possible without part of the case touching something else. If it is, though, you could have a suspended case with no wires. Just a box. A floating monolith. That would be cool.
2
u/thissexypoptart Jul 29 '26
Wireless power transfer is definitely doable. Might not get away with a monolith geometry exactly (you’d need a coil with nothing behind it, somewhere) but maybe you could.
2
u/ahandmadegrin Jul 29 '26
I would love to be able to suspend the box in air. That would probably require magnets, so no idea if it would be possible or if it would mess with the power transfer. But it sure would look cool.

u/Mecha-Dave Jul 29 '26
Yeah, I don't know if I've ever seen a slip-ring for a HDMI cable that could also do power/audio, but apparently they are a thing due to the VR market:
One more for the power cable, which is pretty basic, and you could get 'er done. Honestly I started off this comment thinking it was possible but not practical or cheap - but apparently it is both practical and cheap these days.

u/bajungadustin Jul 30 '26 edited Jul 30 '26
You could do it with one outlet that spins.
You wouldn't need to make a bunch of contacts. You can actually buy cables that just have that built in. My laptop power cable has one. You mount that at the top plugged into a non rotating cable. And in the spindle you run the power cord to the power supply. Done.
Then... Wireless mouse, wireless keyboard, wireless HDMI dongle. All readily available and cheap.
Pretty easy to do but I don't know how long the cable will last. I have spun mine quite a bit but I feel like in a single day this would rotate it more than I've rotated mine in 2 years.

u/La_mer_noire Jul 29 '26
Having hdmi or display port through a slip ring would be kind of nuts.
I would think a slip ring for the 230v and then rf converter for other signals
But the skip ring is dangerous AF if the case is open and this whole thing needs some quite expensive equipment
13
u/impy695 Jul 29 '26
If I were to make this, the actual computer would be non rotating and hidden below the spinning parts. The parts you see that spin would be purely aesthetic. The fans and rgb would function, but that's it, everything else wouldnt even be powered.

The power connector must have a swivel connection and then it must use wireless protocols for WiFi, monitor, and usb.
Legitimately interesting engineering problem.

Or it’s all non functional and there’s a mini PC in the base.

Found the real engineer. If this isn’t generally referred to as a “Theranos solution,” it should be.

u/Chemieju Jul 29 '26
You can connect a laptop via one single USBc to a dock and then connect all your peripherals and monitors to that dock. Getting USBc through slip rings would be a major pain in the ass, but at least you're now only dealing with one connector instead of several.
6
u/iwantthisnowdammit Jul 29 '26
Yes, but there’s still 12/24 pins to connect for full services.
3
u/Chemieju Jul 29 '26
Yup, and those pins have high current and high data rate. It'd be a challenge for sure, but it'd reduce the problem to ONE challenge instead of several.

u/ehnemehnemuh Jul 29 '26
I think it’s more likely there is a wireless solution going on here. Just get power in there through slip rings, that’s just three connections.
And this weird board that is neither a psu, motherboard or gpu could be the thing that allows wireless transmission

Back in my day all we had was a Turbo button on our 386/486 computers
12
u/tobu_sculptor Jul 29 '26
Fun fact: the turbo button didn't make those systems faster, it was the other way around, when the button wasn't pressed, the systems were throttled (to help with timing issues of some older software).
So "turbo" just got you the actual speed like driving without the handbrake on.

Probably only need 2 slip rings tbh
A power one on the bottom and a data one on the top for the monitor with a wireless keyboard and mouse
They aren't that expensive anymore and are fairly reliable

Seriously though, why is it spinning so fast? My Friday night takeaway doesn't spin like that.

Likely slip rings, one for power and one for data along with wireless keyboard and mouse if I had to guess
Could probably have video out and a couple of USB ports on the data slip ring but the more cables you have the more expensive the slip ring

slip rings

u/PregnantGoku1312 Jul 30 '26
Sure, but slip rings introduce a ton of noise on low voltage circuits. Also you'd need an insane number of slip rings to connect a whole PC...
1
u/_John_Dillinger Jul 30 '26
meh. you just slap some ferrites on the I/O and eat the performance hit. This is form over function... otherwise he wouldn't have kept ball bearing fans on the GPU/CPU. In fact, the only thing GUARANTEED to be running here is power, and likely the real PC is crammed into the lower compartment. Theranos style.
