powerful DC-DC

No, are you not aware how these work?

A step down DC-DC is nothing compared to a transformer rectifier or PD electronics with communication with a USB-C.

again, simpler and cheaper electronics for everything

PWM DC to DC dropping voltage to what you need is easy/cheep.

So instead of a big transformer + rectifier that each device has now, it would be a much smaller/cheaper step down at like 99.8% efficiency

Yeah, but frequency drives/inverters were still pretty pricy things back then to for high powered motors for compressors/blowers/etc.

But the cost and efficiency of those things have dropped SIGNIFICANTLY in the past decade..

_ I don’t think USB C PD could handle a hairdryer though_

Of course it wouldn't. The idea would be get rid of USB-C and PD completely.

You'd have 110VDC@15A available for your hairdryer. Heating coils don't care if it's AC or DC, and the blower fan would be a brushless fan.

You're compressors for AC or fridge would be freq drives, which are cheaper because they could drop the rectifier circuit, and highly efficient.

The only real concern about having DC in the home as standard is the safety aspect of DC doesn't let go if you get shocked.

But that is already being worked on in general as many homes have high-voltage DC circuits from solar panels.

No, it's got nothing to do with power over ethernet.

It's simply having only one high power rectifier at the breaker box.

And removing all those rectifiers from every device in the house.

We don't need AC in the home anymore. Every device is now using DC, and any other device will still work with DC.
The only thing really left are motors, but even those are going brushless and we can chop half of the inverter out of the equation of those as well.

And every device won't even need smart electronics for PD either.

It would also solve the North America 60Hz and EU 50Hz issue, where the AC coming in doesn't matter. We all standardize on a DC output.

And when people want to add alternative power (Solar/Wind/etc), it's a HELL of a lot easier to just push the DC into the existing system without having to worry about frequency matching.

220V compared to 110V

[–] ShadowRam@kbin.social 4 points 2 years ago (6 children)

4,6,7,10

I don't know. I know I played 9 in its entirety, but it is completely un-rememberable.

But yeah, 100% lets get back to the turn-based formula it was meant to be.
Bonus if we could go back to a 5-team instead of a 3-team

[–] ShadowRam@kbin.social 1 points 2 years ago

This is exactly why I op'd for Kbin over just Lemmy.

Lemmy + Mastodon support.

[–] ShadowRam@kbin.social 11 points 2 years ago* (last edited 2 years ago)

Ok I have come to realize that lemmy is literally no better than reddit when it comes to people who are so arrogant in their ignorance.

Or the common denominator is you're clueless.

See, that's the problem with modern science reporting. People are so easily confused.

No. We have never teleported atoms.

We did the equivalent of a fax machine.

We took an atoms current state, sent that information down traditional communication lines, and copied it's state perfectly to another atom.

They call it Quantum Teleportation, but it has nothing to do with Sci-Fi teleportation as most people think of it.

 

I added a hole to be able to release the clip after it clicked. No other changes to it. The original part: https://www.thingiverse.com/thing:2594163 The idea for the hole: https://www.thingiverse.com/thing:5364218

 

Parts designed to use multiple lengths of 1/2 inch Schedule 40 PVC pipe for greater strength and rigidity. . Also may be used with wooden dowels (of appropriate size) if the use of PVC offends your sensibilities.

 

Cable organizer.

 

All the things you need when leaving your home ready to go! A Shelf for your wallet and magnetic holders for two sets of keys. The design has compartments for magnets with a diameter of 10mm max. Blender file included.

 

I wanted to mount my Dremel to a bench, but the original model by Faklam had a ring the Dremel didn't fit though (I later realised that the top can be screwed off). So I cleaned up the model, made the ring bigger, and ended up almost remodelling the whole thing. Unlike the original, the head of the tool is pressed against the small ring rather than going through it, which should be stable enough for most applications. For printing, I used supports for only the most horizontal parts of the rings. In this case I used a 0.6 mm nozzle and a layer height of 0.36 mm, as this model doesn't require much detail :)

 

This design has been updated with AUX port. You can find this new design at: https://www.thingiverse.com/thing:5767765 My PC has USB 3.0 ports only from its back (yes, it is already getting mature). I wanted to bring some of these to my desk to avoid having to 'deep dive' every time I need to connect something reasonably fast way. I have bought this cable and designed under-desk holder for it: PremiumCord USB 3.0 Super-speed 5Gbps A-Ahttps://www.alza.cz/premiumcord-prodluzovaci-kabel-usb-3-0-super-speed-5gbps-a-a-mf-9pin-2m-bila-d6696333.htm I think the design might work for some other brands as well as it is quite common shape for this type of wire. You should use 2 pcs. of 3mm screws to fix it to the table - whichever length works for you, I have used 16mm. Easy to print, but you need to position the objects properly to the printing bed. Consult the picture for object orientation on the bed. I have used 0.6mm nozzle, orange PETG filament, 55% infill and supports. Happy printing :o]

 

100mm flexi hose holder

 

Deux appareils pour faciliter l'ouverture des bouteilles avec bouchons vissés. pour les fixer sur votre réfrigérateur vous pouvez coller 4 aimants diamètre 6X2mm. Voici un lien pour les aimants. Vous pouvez imprimer séparément les deux fichiers. https://www.amazon.fr/gp/product/B07RT9MY52/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 Two devices to facilitate the opening of bottles with screw caps. to fix them on your refrigerator you can stick 4 magnets diameter 6X2mm. Here is a link for the magnets. You can print both files separately. https://www.amazon.fr/gp/product/B07RT9MY52/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1

 

Small latch for cabinet, little door, to attach something to other thing. Works well also as printer test. Gap between parts is 0.2 mm. Can be printed fully working on place without supports as shown on video. If you have problems with movement most likely problem is stringing. https://youtu.be/MCwRCMNyMc4

 

This adaptor is to connect 1 1/4in hose to 1 1/4in hose. I've used 2x R-20 o-rings and it seems to seal well or you can use Intex 1.25in Dia Hose Seal.

 

Similar to a previous design (https://www.thingiverse.com/thing:6088152), but much better ventilated. I'd been wanting to use a Voronoi pattern in a project and discovered an online resource for converting 3d models into printable "Vorinated" bodies (https://www.voronator.com/). The site has its limitations, but it's free and easy to use. The alternative is to use a Voronoi plug-in in your design software which will give you a lot more control. I printed this vertically without a raft or supports. It's a good idea to bury the model into the build plate a little bit (say 1mm) so you have a decent base layer to start from. This will string a little so maybe turn down your hot end temperature or up your retraction. I did neither and it turned out fine.

 

Updated20230727 Someone send me feedback that the snap place is too tight and hard to separate, so I modified all 4 models, you can try the new one. Updated: Someone said the angle of the hanger is not good, it might form a bad shade of the clothes, so modified the angle, you can download the"Foldable Hanger_angle" and"Foldable Hanger_tight_angle" files to replace the old one. It's a Foldable Hanger that can be printed all at once and with no support. Specially designed for travel, very compact and reliable. There are 2 versions, the tight one for high-precision printers and a normal one for others. watch the video for more information: https://youtu.be/QII3ODl7uRc Click"like" for me if you really like it, it will encourage me to design more new things.
