On the legalization front, Cato is definitely on the libertarian end of the spectrum of conservative think tanks, so that does line up

For context, this article is an opinion piece co-authored by: Jeffrey A. Singer - A senior fellow at the Cato institute, a republican think tank that receives much of its funding f…

Except that the author of ruamel.yaml: refuses to use git [0] refuses to take community submissions (except through Stack Overflow? Seems like a misuse of SO) [1] and refuses to im…

Ethernet usually has magnetic isolation through tiny transformers (oftentimes included inside the ethernet PHY IC) to avoid any issues with different ground potentials and such.

I still think Tile lost out on a gigantic market by not making it easier for hardware manufacturers to integrate into their ecosystem. They should have been practically begging oem…

Aluminum Nitride actually has a favorable formation so they have to use much less friendly gasses like Sulfur Hexaflouride.

I mean most GIS software is pretty aware of precision models. Take GEOS for example, it's got a variety of ways to specify the precision in number of decimal places for a geometry.…

I really think #EndPatents is a very software oriented view of tech. In the physical engineering space patents are the only thing that allows a small company to actually design, ma…

Yeah I think it's just how news media works I guess. Especially since 3D printing is a cool technology that hasn't quite hit it's stride yet, people are want to see how it's going …

I'd say the real hype cycle for FDM was in 2013-2015, as evidenced by the SSYS stock price [1] (many other 3D printing companies have similar curves). I think we're now on the tail…

They are pretty fundamentally slow because of the constraints from the melt pool. Because you are trying to locally melt the material (lots of energy) and then immediately solidify…

Minutes is a stretch. It will likely take multiple tools and setups to make a mold, and even more if you're starting from a billet that needs facing etc.

Apple actually gets a decent amount of coverage for their very impressive injection moldings. Most advancements in IM today are not in the ability to make complex parts, but more i…

Plastic scrap value is near zero [1] when compared to Aluminum [1] https://webcache.googleusercontent.com/search?q=cache:fZ0f_O...

Yeah the plastic isn't recyclable, but e-waste is full of precious metals and structural metals like aluminum that can easily be recycled.

You'd be surprised actually! Prusa uses no gearing between the motor and the primary drive gear and it's a 200 step/rev NEMA 17. You can transmit high frequencies quite easily, and…

I'm pretty sure it's actually just a continuous under extrusion. It becomes periodic in nature because material gathers under the nozzle and then it hits the blob from the previous…

You're talking about a $40 tool just to flash the storage vs a part (micro SD adapter) that they give you with the SD card for free because it's so cheap. Also doing a quick survey…

If they didn't use SD cards, the storage would be more reliable, but users would spend a lot more time fixing bricked boards. By allowing for removeable storage (in a format that c…

> People limping might serve as example that a 'state of the art, well trained neural net' can't achieve good motion with less than perfect hardware. I think that people limping ha…

They're actually using servo motors! They refer to it as a "servo-driven parallel gantry system" in the abstract.

Checkout the second to last page for pictures: https://arxiv.org/abs/1709.05918 I think you bring up a good point about the lack of precision at high speed. I think the next big th…

> Although, I disagree that a screw drive is needed. I use hobbed gearwheel drive on my extruders and rarely is the issue the hobb slipping. Typically, it is the motor stalling ins…

It's actually just a standard 4-40 thread cut into the filament. They use rollers to prevent rotation of the thread when cutting the threads into the filament, and then when they a…
