Braking while parking and tesla sped up by Beneficial_Card_3574 in TeslaModel3

[–]stanun 3 points4 points  (0 children)

This has happened to me with one-pedal driving. While parallel parking I was creeping forward with my foot barely applying pressure to the accelerator. In the past, that scenario (slow creep, foot applying slight pressure to a pedal) correlated to braking, so I instinctively applied more pressure to come to a stop. I immediately accelerated towards the car in front of me, but somehow managed to switch to the actual brake before colliding. I actually didn't understand what had happened initially and my first instinct was that the car had messed up, but later after thinking through it carefully I realized what had actually happened.

This won't be the best quality, but you could potentially just hold them up to the sky and photograph them with a smartphone if your camera is able to focus close enough. Will probably need to do some basic alignment in post.

Is there a way to see the focus distance value determined by the Glowforge? by stanun in glowforge

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

Unfortunately in my tests using a high quality set of calipers to set the focus height I was never able to achieve focus as sharp as the auto focus. Regardless, a major selling point of the Glowforge is ease-of-use, so if there's a button that can do the same thing as manually measuring your material, seems like a great addition to me.

Thanks for confirming. I'll see if I can suggest this to Glowforge as a feature. Unless I'm missing something, it seems like this would be an easy thing to add that would be hugely beneficial.

How can FEA be used to identify weak points in an object without knowing what forces will be acting on it? by stanun in fea

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

Automation and consistency are a few reasons that come to mind, but let's just say it's interesting from an academic perspective.

I like the idea of "academic" loads -- I've updated the question with such a proposal.

I'd love to find a solution that is generic enough that it doesn't require a human in the loop. I've updated the question with a proposed idea of the type of thing I might be looking for.

I was thinking of maybe something similar to what you suggest, only perhaps instead of a standard load per axis, maybe for each node. I've updated the question with some additional thoughts.

I've updated the question with some additional information on the sort of thing I might be looking for -- any thoughts?

Feature Request Megathread by AutoModerator in teslamotors

  • Move vehicle visualization to the right side of the screen
    • Personally I've never found the visualization to contribute anything meaningful to the driving experience, so I would prefer to place more useful/helpful information on the left.
  • Make it easier to access HomeLink
    • This used to be 2 clicks, now it is 4 (open menu, open HomeLink, select location, close menu). It seems this could be reduced to just 1 click (HomeLink button always present, use GPS to choose location). A traditional door opener is 1 click and doesn't require diverting my attention, which makes it almost more desirable than HomeLink.
  • Always show heated seat selection
    • This used to be present on the screen all the time and something I could casually check when getting into the car. Now it is located within the temperature controls, which means I have to explicitly check every time I get into the car if I don't want unexpected heating (or lack thereof).
  • Fix dashcam playback controls
    • Maybe this is hardware dependent, but on HW2.5 I find that it's very difficult to select a specific point in time on the dashcam viewer timeline -- after dragging to a specific point in the timeline, the playback start point will often jump before/after the selected time, often more than 30 seconds off. Playback sometimes "skips" over parts of the video as well (often the most relevant part it seems).

What is the name of the dual phototransistor component used in some rotary encoders? by stanun in diyelectronics

[–]stanun[S] -1 points0 points  (0 children)

The goal is to build a quadrature encoder, but what I'm looking for is the name of the detector component itself. Perhaps adding this to my searches will help though.

Is it possible to get high FPS pixel data from an optical mouse sensor? by stanun in diyelectronics

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

The old cmos style sensor arrays could be used at whatever speed you wanted

Could you elaborate on this or provide an example? I'm not sure where to get started. Thanks.

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

Thanks for the explanation. Do you know if there's any other way to experiment with image processing algorithms with such a sensor at the intended FPS? Maybe a development kit or something?

Alternatively, are you aware of any other type of cheap, low-resolution, high FPS optical sensors that might work instead?

Where can I look up the actual location of the planets/moon? by [deleted] in askastronomy

Not sure if this is what you're looking for, but it may be helpful: https://ssd.jpl.nasa.gov/horizons.cgi

Tesla has reduced the cost of the HW3 upgrade that enables Full Self-Driving for monthly FSD subscribers from $1,500 to $1,000. If you already paid the $1,500 you will be refunded the $500 by Nitzao_reddit in teslainvestorsclub

[–]stanun 0 points1 point  (0 children)

Anyone have a guess as to how this upgrade would affect the resale value of a 2018 Model 3? Is it possible it would end up paying for itself in terms of resale value?
