This 3D-Printed Working Model of a 787's Jet Engine Has Impressive Thrust

Given the challenges with precision, building functional machines with a household 3D printer isn’t easy. And that’s why it’s all the more impressive that someone on the RC Groups forum has used a 3D printer to make a fully-functional scale model of a Boeing 787’s GE-built turbofan jet engine.

Harcoreta’s scale replica, which includes over 60 3D-printed blades and vanes on the inside, isn’t just a model destined to collect dust on a shelf. It actually produces more than enough thrust to power a remote-controlled airplane, and that’s exactly what its creator intends to use it for.

To make the design and build of the replica even more challenging, but also more accurate to the real thing, Harcoreta has even incorporated a functional thrust reverser into his engine. So when he’s eventually bringing an RC airplane in for a landing, he’ll be able to stop his creation in time before it runs off the end of a runway. [RC Groups via The Awesomer]

Become a Mystery Shopper to Earn Some Cash on Vacation

Become a Mystery Shopper to Earn Some Cash on Vacation

Mystery shopping is one of the ways you can make some pocket money in your spare time. If you get assigned to mystery shops at airports, on your next vacation you could not only kill time waiting for your flight, you could earn some money and possibly score free food too.

Daily Finance explains:

Why on earth would you want to spend your vacation mystery shopping? Because mystery shopping companies often have mystery shops in airports and trouble getting them filled. Sinclair Customer Metrics is almost always looking for people to mystery shop major airports. You might even make more money per shop, too, because retailers are so desperate for the feedback. If you have a long layover, you might even be able to earn as much as $100 on mystery shopping gigs. You could end up scoring some free food, too.

Sinclair is just one of the companies that need people to mystery shop at airports (Google “mystery shopping airports” for more).

Hey, you can kill some down time and get compensated in cold hard cash at the same time.
