Shefio’s digital level angle finder gives you precision to the ±0.1° at 0° and 90° and ±0.3° from 1-89°, and resolution of ±0.01° at 0° and 90° and ±0.05°at other angles in degrees, percent slope, inches/feet, and metric.
- Dependably Durable – Construction conditions and tech don’t always mix, but Shefio makes tools that are up for the challenge. This magnetic digital level is IP54 rated, so it’s dustproof, waterproof, and built to last through almost anything you and your projects throw its way.

It's a lower midrange hub from a Giant OEM wheel. Typically these Hubs are manufactured by a Chinese company such as formula, joytech, or novatech. They are solid, although not of particularly exceptional quality. If you're interested in a high quality hub that uses non-cartridge ball bearings like in the GIF, look at Shimano hubs like this Shimano XT.
Amazon? They're pretty common.
If you want some real cool stuff though, go see what /r/flashlight can do with some 18650's.
I don't know if a $3300 powered one exists, but there is this one for under $7k, which is well below your insane $20k guess. I'd like to see exactly what the $3300 one they're referring to is, it could just be some insanely overpriced mechanical one that nobody buys, like those ridiculous HDMI cables they sell on Amazon.
$56 on Amazon, if you were curious like I was.

I've got a Citizen that does that, and it's fuckin' great.
Great reviews too: Amazon
All depends on what you do. Sure, many engineers stay at their desks their whole lives, just as many engineers are out in the field or on the floor working alongside the technicians.
Read Skunkworks. Rich goes into detail a couple times that Kelly Johnson, the father of Skunkworks would make sure his engineers were right next to the assembly line at all times. This allowed the engineers to still design what they needed to work on, but also go right to the floor in a matter of seconds to fix or check what they needed to.
Despite this video's great optimism, the M16 was borderline rejected by troops on the ground for unreliability and the need for constant cleaning. Many troops wouldn't give up their M1s or M14s. A fascinating book on the US service rifle is American Rifle.
Not really the same thing, but I think these are nifty.
http://www.amazon.com/Stirling-Engine-with-LED-Light/dp/B0085IJFGY
Seems like they missed a prime opportunity to make it self cleaning.
Also I think its a gimmic. Those panels are probably only 50-100 watts max each. You can get that much power for less than $1200 on Amazon
Dude... a string of 50, pre-wired and IP68, is $15. 500 for $115.

> This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid, the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. -- from purchase link below
