>Wouldn't the chance of one of those engines failing be much higher?

Turns out that, yes, much higher.

From what I've read, they didn't have the resources to build and test the high-output engines like the F-1. I think with the larger engines, combustion instability becomes a much more difficult problem to overcome. They never really resolved what was causing it in the F-1 and just did a whole bunch of experiments with different injector plates until they found one that worked. They would actually set off small explosives outside the combustion chamber of the F-1 to test how it would respond to pressure differences.

There's a documentary on Netflix called Cosmodrome that talks quite a bit about the development of the Soviet engines that would probably do a good job of answering your question better.

That bike has no suspension. There needs to be suspension for it to ride comfortably and safely at higher speeds. There are already some proto-type hub motors with suspension built into them. This frees up space on the frame for batteries. -> https://www.google.com/search?q=active+wheel

Additionally, water cooling would allow an electric motor to be pushed harder and faster while remaining rather small. Much better than ghetto air cooling like I do on my bikes. --> https://sites.google.com/site/shelbyelectro/motors/mods/ventilating-a-hub-motor

I think crystaylte has a hub motor with 3 speeds. This is important since hub motors are limited to the speed that the wheel itself turns. So if the motor is in a slow and inefficient zone, like when climbing a hill, it would be awesome for it to be able to shift.

TL;DR lots of exciting advances to be made in electric hub motors. Unfortunately, the chinese market is slow at making tech advances. It's understandable considering the leap between an almost stone age primitive dc motor attached to a wheel and cramming suspension, cooling, gearing, AND a motor inside a wheel.

I downloaded the docking theme from interstellar via a app called MP3 music player

I downloaded the drifting video, and went to YouTube, upload, I added the docking theme, cancelled the audio from the drifting video, made it 100% the docking theme, and moved it around until it seemed to match.

Tldr played around with YouTube's uploading functions.

For the lazy

Bootleg helicopter factories are just the tip of the ice burg. There are thousands of industries that produce bootleg/counterfeit computer chips, aviation parts, car parts, and much other stuff that managed to get into-even high end companies you would never expect. Hell for all you know that $6k gaming rig you are using maybe using counterfeit parts. There are pretty good documentaries on this exact subject if anyone is interested:

Edit: Just noticed the video doesn't play where I live for some reason on Amazon. I watched it either on Netflix or Hulu at one point. I used to dabble in electronics engineering a little and watched EEVBlog that had some talking points about counterfeit intergrated chips and how they usually get mixed into the industry, but I can't find the YouTube video at the moment.

I took a higher-resolution picture of some of them; they are contents of machine registers.

The cockpit is behind a Plexiglas wall. I took a picture through the Plexiglas anyway.

Did a quick Google hunt, seems you can get a 10" SawStop cartridge as cheap as $70 on Amazon, but the specialty ones seem to be slightly more expensive.

Here it is on Google Maps.]

EDIT: Here are some more pictures that better illustrate the massive scale of this thing.

Despite being 13 years old it's aged well with higher res settings and all. The game play is great fun. Nothing else like it that's so highly rated. Other copy-cat games are not so good.

According to http://gizmodo.com/5019797/everything-you-always-wanted-to-know-about-lego

"Approximately 19 billion Lego elements are produced per year. 2.16 million are molded every hour, 36,000 every minute."

The video shows a device with an approximately 2 second cycle time. Which would mean 30 cycles per minute x ten Lego per cycle = 300 Lego/minute per stamper. That means 120 of those machines running around the clock! Seems a little high but not terribly so.

For anyone that hasn't read it before The Thrill of Flying the SR-71 Blackbird is probably one of the best articles I've ever read on Gizmodo. Everything about that plane was hardcore.

So, I read a few days ago that there was a problem with the tail hook being too short for carrier landings & I remembered watching this .

Now I'm wondering why is a tail hook even necessary, aside from fuel savings.

A truly bad ass plane no matter what.

Gizmodo ran a longer exert from his book that included that story as well as some others. It was really a great read about an incredible plane. It's still up here.

OOPS... sorry... I have not been interwebing much as of late...

it is weighed by the yard... and common weights would be 90, 100,130, 140 etc

I really want to see a copy of Sled Driver

Can't afford it or find it in a nearby library. Here is an excerpt.

I chose that one because it was the cheapest one with free prime shipping that I found in 30 seconds on the mobile app and I’m a stingy and impatient

Basically a homemade flexible curve template?

Well, he did say it was non-abandoned.

Here's an article in English http://gizmodo.com/5873441/this-girl-sneaked-into-this-russian-military-rocket-factory

I don't know if the link will work; I'm on mobile right now.

Yep, you can spend it directly as Bitcoin at a number of physical locations and websites, or you can get it converted to your local currency at quite a few places as well. Check out this and this for more info.

Once you see the price, you might decide you don't need it afterall.

There's many different sized and designs. I bought this one a couple years back, although it's pointless it's kind of fun. https://www.amazon.com/gp/product/B017LSJKGS/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

Get yourself a copy of Renovating a J Head. I could quite literally hand a copy to (most) of my students and have them tear-down and rebuild a head without stepping in. For anything other than the head, a quick google and Practical Machinists probably has you covered.

Meanwhile a brand new on is $94.97 at Home Depot: https://www.homedepot.com/p/BESSEY-6-in-Heavy-Duty-Bench-Vise-with-Swivel-Base-BV-HD60/205023093

Shucking is removing the green stuff off the corn. Shelling is removing the kernels.

A great source of info on British technology intelligence is "Most Secret War", by R..V. Jones: ->. Jones was Churchill's scientific advisor during the war and did a lot of the work needed to figure out (and eventually thwart) German radio beam navigation (amongst other things). He had a chapter on the V-1/V-2 attacks and also confirmed the mis-direction story. They had the double agents reporting hits in Northern London (when the bombs were hitting downtown). After they started doing this, they saw that the bombs started hitting in the open fields of Kent.

Great book, highly recommended...

Do you have a copy of this book http://www.amazon.com/Steam-Railroads-Electrified-Revised-Edition/dp/0253339790

For US electric railway fans its practically a bible. Had my copy of the first edition signed by Middleton himself at a convention years ago.
