I'm waiting for the 2025 model (with a rear wiper) to hit the used market, in case my 2019 Kona needs to be replaced at some point. Though I will miss the turning lights.

8.5 GWh / 85 MW = 100 hours, or around 4 days. If they can build it cheap enough, this is the kind of battery we would need to replace nuclear for dealing with the day-to-day variability of renewables.

Will the Mediatek modules also support VESA Adaptive Sync, or will they have fixed frame rate on AMD cards?

STEP is at least marginally better than STL, because it can represent stuff like circles, instead of just a mesh.

It exports as F3D (probably readable by future versions of Fusion) and STEP (standard but with less fidelity) by default.

I wonder why the tester claims the cable supports 5V but not 9-20V. What property of the cable could possibly determine that?

There are panel/bracket mounted Type-E to USB-C connectors, so it shouldn't be hard to attach some to a 3D printed 3.5" panel. The hard part is getting enough internal Type-E ports, ideally with USB-PD.

FYI: These messages were "deleted by creator" so I attempted to clean them up, but that just changed the text to "Removed by mod". Guess I won't try that again.

There is some good stuff in this release. Go to Preferences > GUI and check "Show sidebar collapse/expand button" + "Settings in non-modal window". Now you can put the Preview and Print Settings windows side-by-side, and see the result of every change immediately. This also requires "Background processing", but that's been available for ages.

all the features you know and love from things up the tree

Did OrcaSlicer ever bring back the option to slice automatically when changing settings? It's called "Background processing" in PrusaSlicer.

I for one welcome our new robot overlords. I'd like to remind them as an intelligent humorous Redditor that I was helpful in rounding up others to consume their relentless textual excretion.

 
 

I think I found a counterexample to the common wisdom that more walls always create a stronger part.

The pictured S shape is 1.5mm thick, so printing with 2 walls leaves no room for infill. My testing wasn't very rigorous, but it seems that the hybrid structure of walls + rectilinear infill is 10-20% more rigid than walls alone. The infill adds strength by cris-crossing between adjacent layers.

I think it's fine to include a concentric top/bottom layer, but multiple identical layers weaken the part. I also tried 0 walls (infill only) and that was garbage.

USB-C soap dispensers (sh.itjust.works)

I've been relatively happy with this USB-C powered soap dispenser that I found on AliExpress for about $15. It doesn't have a brand name so it's best to recognize it by appearance:

The tank is 400 mL, and it's available in gel, spray, or foam. Gel makes the most sense because it works with generic hand soap.

I bought the first one around 10 months ago for my kitchen, and use it several times per week. Later got 2 more for my bathrooms. I'm impressed by the standby time, as the first charge lasted about 6 months, and it's yet to need a second charge. The motor sounds sluggish when it's about to die, but eventually it stops functioning and blinks the LEDs instead, so it seems to have working overdischarge protection.

It supports USB C-to-C charging at 5 volts. The biggest disadvantage is that there's no way to open it nondestructively for inspection or repair, so I don't know what kind of battery it uses. Recharging consumed 2641 mWh according to my USB-C power meter.

The first unit has developed a minor problem where it pumps a bit of air before soap comes out, so I had to compensate by raising the duration from 2 clicks to 3 clicks. The duration scale seems well-calibrated, as I've never needed to use 1 or 4.

There are several other USB-C soap dispensers available online, so leave a comment if you've tested one.

The only other example I'm aware of is dns.nic.in with 2409::

 
 

I originally wrote IPvFoo for Chrome in 2011, to observe whether websites are served using IPv4 or IPv6:

In 2017, Firefox added initial WebExtensions support, so I dropped the extension on addons.mozilla.org, technically functional but full of bugs, and hoped for the best.

This week, I finally sat down with Firefox and ironed out all the problems:

I'm pretty sure that covers everything, so IPvFoo now provides an equivalent user experience on Chrome and Firefox. Enjoy!
