Jeep Wrangler Dome Light Mod

Posted on by

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

Hacker Challenge: Sail the Atlantic

Posted on by

We found it incredible that — apparently — no one has sailed an autonomous sailboat across the Atlantic successfully. Compared to an electric craft, sail-powered platforms ought to reduce having to carry batteries or other fuel and enable long-duration missions. The problem, of course, is the sailing conditions in the Atlantic.

The challenge is the focus of the Microtranssat challenge which started in 2010. You can think of the challenge as a race, but not in the conventional sense. Participants can launch their 8 foot (or less) craft any time between July and December, and it doesn’t matter which direction …read more

Retrotechtacular: How To Repair A Steam Locomotive

Posted on by

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

Posted on by

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

Star Wars Speeder’s Finishing Touch: Mirrors

Posted on by

[Super 73] make electric scooters, and they made some Star Wars Speeder Bikes with a twist for Halloween; adding some mirrored panels around the bottoms of the bikes made for a decent visual effect that requires no upkeep or fancy workings. Having amazed everyone with the bikes, they followed them up with a video of the build process.

The speeders are shells built around their Super 73 electric scooter, with bases of what looks like MDF sitting on anchor points. Onto the base platforms goes cardboard and expanding foam to create the correct shapes, which are then sanded then coated …read more

3D Printed Hovercraft Takes to the Air

Posted on by

Instructables user [John_Hagy] and some classmates built an RC hovercraft as their final project in the Robotics Education Lab at NC State University. It’s a foam slab with a Hovership H2204X 2300Kv brushless motor inflating a skirt made out of ripstop nylon. Nylon is great here because it has a low friction coefficient and is nonporous to keep the air in. A second motor propels the craft, with a servo turning the whole motor assembly to steer. The team designed and 3D-printed fan holders which also help channel the air to where it’s supposed to go. Control is via a …read more

Trainspotting with Junk, for Science

Posted on by

[Douglas] hometown Goshen, Indiana takes the state’s motto ‘The Crossroads of America’ seriously, at least when it comes to trains. The city is the meeting point of three heavily frequented railroad tracks that cross near the center of town, resulting in a car-traffic nightmare. When everybody agrees that a situation is bad, it is time to quantify exactly how bad it is. [Douglas] stepped up for this task and delivered.

He describes himself as cheap, and the gear he used to analyze the railroad traffic at a crossing visible from his home certainly fits the bill: a decades-old webcam, a …read more

Printed Parts Make DIY Electric Longboard Possible

Posted on by

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

Posted on by

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

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
