3D Printed Hovercraft Takes Flight

Last time we checked in on [Ivan Miranda] he was putting a drill press on the Internet. Lately, he has been trying to 3D print a hovercraft with some success. He made four attempts before arriving at one that works fairly well, as you can see in the video below. We will warn you, though, the screwdriver cam is a bit disconcerting and we suggest waiting at least an hour after you eat to watch.

The starboard impeller broke midway through the test, although with a single impeller it was working pretty well. [Ivan] thinks he can print the impeller …read more

Fail of the Week: Engine Flips Out

A few weeks ago an incredible video of an engine exploding started making the rounds on Facebook. This particular engine was thankfully in a dyno room, rather than sitting a couple of feet away from a driver on a track. We’ve all seen engine carnage videos before, but this one stands out. This diesel engine literally rips itself apart, with the top half of the engine flipping and landing on one side of the room while the bottom half sits still spinning on the dyno frame.

Building performance engines is part science, part engineering, and part hacking. While F1 racing …read more

Boxes, Form An Orderly Queue Behind The Armchair!

If you have ever been to a hacker camp, you’ll know the problem of transporting all your stuff to your hackerspace village, or to wherever you’ll be basing yourself for the duration. The car park is always too far away, whatever trolley you’ve brought along is never big enough, and the terrain you have to drag everything over feels more like the Chilkoot Trail than a city sidewalk.

[Jan Henrik] and [Niklas Fauth] have an effective solution to all your hacker camp transport woes, in the form of a motorized platform designed to carry a storage box. Underneath the platform …read more

Jeep Wrangler Dome Light Mod

If you’re the owner of a Jeep Wrangler, you may have experienced some frustration with the interior dome light. For those not in the know, removing the doors on a warm day or for a bit of fun can lead to a dead battery. This happens because the Wrangler’s light stays on unless the fuse or light are removed, or a custom shutoff switch is added — at the expense of troublesome wiring. You could say it’s a Jeep Thing. [Tim Nummy] offers a solution with minimal modifications.

First off, pop the switch out of the door and set it …read more

Retrotechtacular: How To Repair A Steam Locomotive

Steam locomotives, as a technological product of the 19th century, are not what you would imagine as fragile machines. The engineering involved is not inconsequential, there is little about them that is in any way flimsy. They need to be made in this way, because the huge energy transfer required to move a typical train would destroy lesser construction. It would however be foolish to imagine a locomotive as indestructible, placing that kind of constant strain on even the heaviest of engineering is likely to cause wear, or component failure.

A typical railway company in the steam age would therefore …read more

Your Drone Is Cool, But It’s No Jet Fighter

There are some communities with whom our happy band of hardware hackers share a lot in common, but with whom we don’t often associate. The more workshop-orientated end of the car modification or railway modeler scenes, for instance, or the model aircraft fraternity. Many of these communities exist more for the activity than for the making, some of them dabble with building kits, but among them are a hard core of people who create amazing projects from scratch.

Take [Igor Negoda], for example. Not content with building just any model aircraft, he’s built his own from scratch, to his own …read more

Printed Parts Make DIY Electric Longboard Possible

Appalled by expensive electric longboards, [Conor Patrick] still wanted one, and wanted it now. So — naturally — he converted an existing board into a sprightly electric version at a fraction of the cost.

[Patrick] is using a capable 380KV Propdrive motor, capable of pushing him up to 30mp/h! A waterproof 120A speed controller and 6000mAh, 22.2V LiPo battery slim enough to fit under the board give the motor the needed juice. He ended up buying the cheapest RF receiver and remote combo to control the board, but it fit the all-important “want electric long board now” criterion.

Initially, [Patrick] …read more

Inductive Loop Vehicle Detector Gets Modernized

Much like George Lucas and the original Star Wars films, many of us may find that our passion projects are never quite finished, especially when new technology comes around or we just want to make some improvements for their own sake. [Muris] was featured a while back for a vehicle detecting circuit, but is back with some important upgrades to his project. (Which, luckily, do not include any horrible CGI aliens.)

For starters, the entire project has been reworked from the ground up. For anyone unfamiliar with the original project, the circuit detected a vehicle via an inductive loop and …read more

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

Instrument Packed Pedal Keeps Track of Cyclist’s Power

Exactly how much work is required to pedal a bike? There are plenty of ways to measure the power generated by a cyclist, but a lot of them such as heavily instrumented bottom brackets and crank arms, can be far too expensive for casual use. But for $30 in parts you can build this power-measuring bike pedal. and find out just how hard you’re stoking.

Of course it’s not just the parts but knowing what to do with them, and [rabbitcreek] has put a lot of thought and engineering into this power pedal. The main business of measuring the force …read more
