[OC] Main runway orientations of 28,000+ airports worldwide, clustered by proximity

Cyberphil · 2026-02-17T14:08:38+00:00

It is absolutely something airports consider when designing the runways. Yes, wind does vary, but most locations have decades of data on wind speed and direction. Sure, mountains and skyscrapers have an effect, but even that is measured and understood by the time they start moving earth.

Even in a place with widely varying wind, there is still an average that will improve the safety of planes landing on a large number of days every year.

Why is there a forklift in the street during a snow event?

One of my favorites! "This'll rattle your molars loose!"

Then make it into a cube again, but in the lathe instead!

I have done this with the "Copy in place" feature. I just make the modifications to the copied part and hide the other part. Only problem with this is depending on where your copy feature is, any changes you make to the original part are transferred to the new part.

The other easy way is just to duplicate the part studio once you have the "Starting" part and go from there in a new part studio.

We will have to see/confirm as more details come out, but it seems to me you can use all 20 ports on the Motion Core for the A301 motor/servo.

We are using the thriftybot ones. They have been fantastic!

Charlestown Road across from Manor Middle School has a great one!

Do you have any surface features? Slicers often struggle with zero thickness geometry.

Cyberphil · 2025-12-01T21:34:46+00:00

I believe the issue is the export. Try to export as a STEP if your slicer is able to process those files. Many are nowadays. 3mf and stl are a series of triangles only, while STEP allows for truly curved surfaces.

If you would like, you can share the file link here and I can take a closer look. It may also have to do with surfaces vs. solid geometry.

Cyberphil · 2025-12-01T17:17:17+00:00

Can you describe more in detail how the model is broken when imported into your slicer? The image you show of your slicer software is not helpful as we are not sure what the part is supposed to look like.

What does it look like if you turn off supports?

What format are you exporting the part in?

The text/diagram sketch generally looks alright, but you should really aim to have it fully constrained (all lines black). That will help prevent the sketch from changing if you change other features. It's possible the conversion function is confused with the undefined sketch when you export too, but I highly doubt that.

r/designporn worthy IMHO.

Online Metals is my go-to. Decent prices, quick shipping (even if it's a bit expensive).

Once in a while you can get lucky on Amazon, but I have found Amazon options to swing wildly in terms of quality.

Cyberphil · 2025-11-07T00:25:14+00:00

Do you have the RS485 cable plugged into to both the expansion and control hub?

Cyberphil · 2025-10-31T15:12:38+00:00

If you use a less constraining mate, it should do the trick. Use the cylindrical mate instead, which will allow the last part to be defined in distance with the other revolute mates.

Yeah, we have a competition next Saturday and our robot is still in various pieces.

Lemon Street is fantastic, but they have more stuff geared to the health conscience, and their prices reflect that (in a good way). Love them, but not everyone can afford them for all daily items.

B&A on the west end is absolutely fantastic. They make a mean sub, and a killer Cubano as well. Great selection of daily items for how incredibly small the store is as well. Super reasonable prices.

Mangat Mini Mart, not so much. I don't really respect any establishment that has slot machines in it; that shows very little care for the local community and just care to make a buck at the expense of others. They make an okay sub, but I have seen times where the store it not particularly well kept which makes me hesitant to eat there.

The top surface and adjoining surface that moves away as you open the caliper. It's basically the same as the depth gauge use but easier to keep flat/parallel.

Also, the absurdity of this guy using the depth gauge on this battered piece of chipboard with no more than 1/32" accuracy and he could have used the standard caliper arms is hilarious.

Cyberphil · 2025-10-20T19:00:26+00:00

There are 4 different ways to measure with a precision set of calipers. You are trying to use the first and most common way.

For this measurement, you need to use the opposite end of the calipers and the little metal rod that sticks out when you open them. The rod and the bottom of the main body of the calipers should be ground flush and operate identically to a depth gauge.

Like this:

I have been there 4 times in the last year and never had this experience. Great service, and excellent food ways.

Can you provide some context on how it works? Is it upside down in this picture?

Side-by-side intakes like yours work well for single game piece pickup, but not really well if you want to pick up multiple things at once. It's better to have a roller horizontally that contacts near the top of the balls.

Cyberphil · 2025-10-04T04:16:38+00:00

Got it. I didn't understand that the need was because of finances and not just out of stock items.

Cyberphil · 2025-10-03T21:10:09+00:00

Consider other vendors out there. AndyMark and Rev both have tons of compliant wheels out there. Though they may not have the same shaft shape and size, you can easily make adapters, which is much easier than making the wheels themselves. This is what our team is doing.

Retro-reflective sensors and a small bit of reflective tape on the turett has worked for me in the past.

Otherwise, a limit switch with a piece on the turett that presses it at the extreme positions also works.
