How To Build An Airplane In A Month And A Half

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

Lithium Ion Versus LiPoly In An Aeronautical Context

When it comes to lithium batteries, you basically have two types. LiPoly batteries usually come in pouches wrapped in heat shrink, whereas lithium ion cells are best represented by the ubiquitous cylindrical 18650 cells. Are there exceptions? Yes. Is that nomenclature technically correct? No, LiPoly cells are technically, ‘lithium ion polymer cells’, but we’ll just ignore the ‘ion’ in that name for now.

Lithium ion cells are found in millions of ground-based modes of transportation, and LiPoly cells are the standard for drones and RC aircraft. [Tom Stanton] wondered why that was, so he decided to test the energy density …read more

3D Printed Tyres Let You Drive on Water

[Jesus] apparently walked on water, without any tools at all. But when you’ve got a 3D printer handy, it makes sense to use it. [Simon] decided to use his to 3D print some tyres for his R/C car – with awesome results.

[Simon] started this project with a goal of driving on water. Initial experiments were promising – the first design of paddle tyres gave great traction in the sand and were capable of climbing some impressive slopes. However, once aimed at the water, the car quickly sank below the surface.

Returning to the drawing board armed with the advice …read more

The Ultimate FPV Cleans House

With much of the world in the doldrums of the winter, hackers are getting a bit stir crazy. [Notamed Closed] would much rather be outside flying his First Person View (FPV) quadcopters. Sure there are indoor drones, but [Notamed] wanted to keep grounded. He grabbed his R/C equipment, his Roomba, and of course an Arduino to build the ultimate FPV experience.

There aren’t many details on this build, but it’s not too hard to deduce what [Notamed] has done. He’s using a standard R/C transmitter and receiver. Instead of driving servos, the receiver plugs into an Arduino Uno. The Uno …read more

Remote Controlling A Dog

Until the industrial revolution, humans made use of animals to make our labor easier. This is still seen in some niche areas, like how no machine yet has been invented that’s as good at sniffing out truffles as pigs are. [William] has hearkened back to humanity’s earlier roots, but in a more modern twist has made something of a general purpose dog that could feasibly do any work imaginable. Now his dog is remote-controlled.

[William] accomplished the monumental task in a literally cartoonish fashion using the old trope of hanging a hot dog in front of something’s face to get …read more
