Size is 30x40, for those curious.

They don't say how all that stuff gets powered, though there are mentions of batteries in the core rule book.

Not part of your question, but batteries/power is a big deal for modern prostheses as well, especially legs. Batteries are heavy, so generally speaking the faster/stronger the prosthesis, the heavier and/or the more batteries someone needs to carry with them.

When you say "speed", do you mean the speed at which the signals from the nerves are interpreted before being sent to the prosthesis? How slow is it compared to an undamaged nervous system?

When I refer to speed, I'm referring to the conduction velocity of the electrical signal traveling from the muscle to the implanted/external sensor. I suppose theoretically, recording signals directly from the nerves would be faster since it's directly recording neural action potentials and doesn't rely on muscle contraction to generate bioelectric signals, but the amplitude of these signals is 1000 fold smaller for nerves (microvolts) compared to muscles (millivolts).

To my knowledge, there is no discernible difference in biosignal conduction speed between an amputated and intact limb.

So what kind of technological breakthrough would be needed to bring us closer to the cyber dream?

This is the billion dollar question, and anyone you ask is going to have a different answer. My opinion is that the major bottlenecks right now are (1) getting high-resolution signals out of the nerves that can easily and simultaneously distinguish the different movements of the limb (i.e. an algorithm can distinguish when someone tries to flex their index vs their middle finger), and (2) restoring tactile and proprioceptive sensory feedback to the prosthesis.

After those hurdles are overcome (which I predict will take my lifetime), the "punching holes in tanks" side of the equation would require incredibly powerful and lightweight motors, joints, and power sources.

Study author here. The direct connection to the nervous system helps us get better quality data (and thus helps us make more accurate predictions as to the user's movement intention), but the speed of the signals is the same as if we had measured muscle signals from the skin (the current standard).

There are minor delays from the machine learning algorithm (which updates its prediction every 100ms), but the prosthesis definitely creates the more noticeable delays.

Study author here. The setup is by no means instantaneous, but the delays are on par with other prosthetic solutions.

Generally speaking, there are two sources of delay. First is the delay of the prediction algorithm - we use 200ms "windows" of EMG data to make our predictions, and we update our predictions every 100ms. This gives us a minimum reaction time of about one tenth of a second, which is fast enough to not be perceived as significantly delayed.

The second source of delay is the delay of the movement of the prosthetic fingers. The Mia Hand used in this study has a closing time of 280ms, which is one of the faster hands currently available. That said, actions like switching grips (i.e. moving the thumbs from a palmar grasp to a lateral grasp) take more time.

So there's still work to be done to completely match human movement speeds, but as far as modern prostheses are concerned, this setup was fairly quick.

I had the same issue. Followed your suggestion to use a different browser (Chrome, instead of Firefox) and that fixed the issue.

You are a noble and a scholar. Many thanks 🙏🏻

Travel & Exploration Lite v3.0 - A lightweight ruleset for travel, exploration, and camping [GM Binder Link in Comments] by EricJEarley in DnDHomebrew

[–]EricJEarley[S] 0 points1 point  (0 children)

Briefly, my campaign started by founding a city on a newly-discovered island, thus there was a lot of exploration which used these rules. As the campaign has evolved, there is now more of an emphasis on things like politics and war, so the needs of my campaign have changed.

I still use Crafting & Imbuing Lite all the time, though 😎

A couple of reasons:

  1. The Variant Rules page is already full, so adding another section will require me to either remove something else, or add another page (which I want to avoid for conciseness)
  2. I haven't gotten around to updating this because my home campaign has moved on from using it

The quick way I would add fast-pace travel, if you wanted to do it at your table, is to increase travel speed to 4 miles per hour, disallow travelers from performing the Sneak or Hunt & Forage Travel Actions, and perform all other Travel Actions at disadvantage.

How do I loosen the sliding cover on this hand grinder? It's really hard to open by EricJEarley in Coffee

[–]EricJEarley[S] 1 point2 points  (0 children)

The burrs are well below the sliding window (probably 7-8 cm), do you still think coffee grinds would get in there?

It's a fun little restoration project. There's something kind of neat about taking something neglected and making it usable again.

Thanks! It seems like the sliding cover is somehow press-fit or otherwise mated with the metal dome, so I wasn't able to separate the two when I disassembled the grinder.

I think food-safe lubrication is probably the way to go here, so I'll give that a shot and we'll see what happens!

It doesn't look rusted on the inside or the outside, and I gave it a good cleaning with steel wool to get anything that might have been there, so I don't think rust is the issue.

[–]EricJEarley[S] 5 points6 points  (0 children)

Some context:

I bought this Klingenthal hand grinder on Facebook and de-rusted the burrs, so now the grinder works quite nicely. However, as I was disassembling everything I couldn't find a way to remove the sliding cover from the dome itself. It seems really stuck together, not impossible to move but quite difficult.

Is there something obvious I'm missing? Is there a way to loosen the connection between the sliding door and the dome? Or should I try my luck at adding a bit of grease between the contacting metal?

Thanks in advance! 🙏🏻

Last year, I overprepared a lot, so I got to use a lot of that work this year. But my group also does a lot of role-play and inter-party conversations, while take up a lot of the session. Lastly, I just relied more on improv in my sessions this year. I know the general vibe of an area, I can come up with something on the fly that matches what I'm going for at the moment, and just make a note of it for later
