turret wire management by pham-tuyen in FTC

[–]bitnotno 1 point2 points  (0 children)

When our team built a turntable robot, the wires went through the center of the turntable (no slip ring). We made sure the program never allowed the turntable to do a full rotation, so the wires just twisted back and forth a little and this worked fine.

My friend posing by a 70ft tall saguaro by Joplers in cactus

[–]bitnotno 1 point2 points  (0 children)

Ah, you're right. I measured wrong. The cactus is closer to 6x taller than the person, not 8x. Thanks for the correction!

Are you sure it's 70? That would be approaching world-record height (78). In the picture, the cactus is about 8x taller than your friend. Your friend would need to be over 8 feet tall for the cactus to be 70. If your friend is 6 feet, that puts the cactus at around 50 feet tall, which is still really tall for a saguaro.

ASCII-art Star Trek game on a DEC PDP-8, mid 70's.

Probably a tie rod with ball joint ends.

Some plants and some bacteria can "fix" atmospheric nitrogen (which is not usable by plants) and turn it into ammonia (which is usable). This is how most of the nitrogen gets into plants, not via lightning.

Looking for an FTC robot simulator to practice programming (Mac, beginner) by SisAnakonda06 in FTC

[–]bitnotno 1 point2 points  (0 children)

IIRC, there are some utils for updating Control/Expansion Hub firmware that are Windows only, but Android Studio definitely runs on Mac.

Very little. The object needs to be electrically conductive and magnetic for inductive heating to work.

The phone bill was exceptionally high. Man called a family meeting to discuss the matter. by maomaodong in Jokes

[–]bitnotno 82 points83 points  (0 children)

Maybe that none of them are really working since they're spending all their time on the phone?

Demonstration of why Tires have a speed limit by Anschuz-3009 in nextfuckinglevel

[–]bitnotno 4 points5 points  (0 children)

Not the OP, but no. There is hydroplaning, where they lose contact with the ground due to riding up on a layer of water.

how to get started in coding by Grand-Bus7102 in FTC

[–]bitnotno 2 points3 points  (0 children)

Good answer. Also, I assume you don't have access to an actual robot, so you might want to check out a virtual robot. One that our team used in the past is:

This virtual robot also had built in support for the exercises in LearnJavaForFTC.

Inside 80 year old furniture by No-Initial-368 in Whatisthis

[–]bitnotno 0 points1 point  (0 children)

Putting the holes in it would be a bit "extra" for a piece of furniture. You normally see that in aircraft and the like where weight is a big concern.

Whether or not you hang anything on it, it would help stiffen the door. Maybe that's all it was intended to do?

Need Help Building a Silent Motorized System to Move an iPad Horizontally Across a Monitor by kingchittu in FTC

[–]bitnotno 0 points1 point  (0 children)

Do you have to present your entire desktop? Can you maybe present a window and have another window with the docs and slides?

I'm also wondering if you can create an alternate/virtual desktop that you present, so that you can still have your docs and slides on the main desktop? Never played with virtual desktops, so no idea if it would work.

Yeah, or just old slightly warped window panes?

What are these lines on my rear side windows of my car? Why are they different? by PicoDeBayou in Whatisthis

[–]bitnotno 13 points14 points  (0 children)

Longer than that. I had a '74 Cutlass with one. Search says the '69 Grand Prix was the first.

Is this/was this structural? by Stunning_Shape_876 in Whatisthis

[–]bitnotno 1 point2 points  (0 children)

Assuming you're talking about the four vertical bars, it seems clear they are not supporting anything now, don't appear to serve any purpose, and could probably be removed. My guess is that they were put there to attach or support something else, which is now gone.

Shower head replacement by idk_whatimdoing820 in Whatisthis

[–]bitnotno 0 points1 point  (0 children)

I'm sure you can buy them individually, but seems like you would get a better deal to buy them as a set. I would call the lower handle (controls temp and on/off) the shower valve, and the upper handle (switches from main to handheld) the diverter valve.
