How To Build An Airplane In A Month And A Half

Posted on by

For the last few weeks, RC pilot extraordinaire [Peter Sripol] has been working on his biggest project to date. It’s effectively a manned RC plane, now legally a Part 103 ultralight. Now all that work is finally bearing fruit. [Peter] is flying this plane on some short hops down a grass runway. He’s flying it, and proving that you can build a plane in a basement, in under two months, constructed almost entirely out of insulation foam.

[Peter] has been documenting this build on his YouTube channel, and although the materials for this plane are mostly sourced from either Home …read more

Remember when you first saw a USB port in a standard wall outlet? It was a really great idea at the time, but how’s that 500mA charge holding up now? Fresh from a random press release, here’s a USB 3.0 wall outlet, with USB A and C ports. 5A @ 5V. Future proof for at least several years, I guess.

This is what you call ‘pucker factor’. An Air France A380 traveling from CDG to LAX suffered an uncontained engine failure somewhere over Greenland. Everyone on board is fine, except for the fact they had to spend the night in …read more

BREAKING NEWS: APPLE HAS RELEASED A NEW RECTANGLE. IT IS BETTER THAN THE PREVIOUS RECTANGLE, WHICH WAS A LESSER RECTANGLE. SOME PEOPLE ARE UNHAPPY WITH THE NEW RECTANGLE BECAUSE OF [[CHANGES]]. THE NEW RECTANGLE HAS ANIMATED POO.

Mergers and acquisitions? Not this time. Lattice Semiconductor would have been bought by Canyon Bridge — a private equity firm backed by the Chinese government — for $1.3B. This deal was shut down by the US government because of national security concerns.

[Jan] is the Internet’s expert in doing synths on single chips, and now he has something pretty cool. It’s a breadboard …read more

Hulk Hands! Who remembers Hulk Hands? These were a toy originally released for the 2003 Hulk movie and were basically large foam clenched fists you could wear. Hulk Hands have been consistently been re-released for various Marvel films, but now there’s something better: it’s the stupidest tool ever. Two guys thought it would be fun and not dangerous at all to create cast iron Hulk Hands and use them as demolition and renovation equipment. This is being sold as a tool comparable to a sledgehammer or a wrecking bar.

New Pogs! We’re up to 0x0C. Is your collection complete? …read more

Building An Ultralight Out Of Foam In A Basement

Posted on by

[Peter Sripol] is something of a legend in the DIY RC aircraft crowd. He’s friends with Flite Test, and there he built an enormous RC cargo plane that could easily carry a small child aloft. Now, [Peter] is aiming a bit higher. He’s building an ultralight — a manned ultralight — in his basement. It’s made out of insulation foam.

Yes, this ultralight is constructed out of insulation foam, but you can think of that as just a skin. The real structure here comes from a wooden frame that will be fiberglassed. The design of this aircraft is an electric, …read more

Hackaday Prize Entry: Modular Instrumentation For Aircraft

Posted on by

Parts, tools, and components for aviation and aerospace are sold in ‘Aviation Monetary Units’ (AMU). Right now, the conversion factor from USD to AMU is about 1000 to 1. This stuff is expensive, but there is a small portion of the flying community that prides itself on not breaking the bank every time something needs to be replaced. Theses are often the microlight, ultralight, and experimental aircraft enthusiasts. Steam gauges are becoming obsolete and expensive to repair, and you’re not going to throw a 15 AMU Garmin G500 in an ultralight that only costs 10 AMU.

To solve this problem, …read more
