Teardrop Camper Combines Simplicity, Style, And Function

July 10, 2013 by Mike Szczys 1 Comment

They needed a place to stay on road trips and at music festivals. This teardrop camper certainly fits the bill. And it’s got a look that will make you proud to unfold yourself into the parking lot every morning.

Starting from a flat frame the camper skeleton was built up using plywood sides and cross pieces to help support the sweeping roof. It was then covered with 1/4″ Birch plywood which has enough flexibility to follow the contour. Inside you won’t find much in the way of frills, but the entire floor is a 4″ thick foam mattress which is a lot better that camping out. There’s a dome on top which can opens for ventilation and a hatch on the rear to carry some extras along on your adventure.

Manual Transmission For Gamers

manual-transmission-for-gamers

If that stick shift just doesn’t feel right in your hand it’s time for a change. This hack puts a gaming joystick in the center console of your hoopty as a gear shifter.

[Ilias] used a joystick from about 1991 to replace the stock shifter. It jogs our memory when he mentions that this thing saw a lot of use playing X-wing vs. Tie Fighter. Boy did we burn up a ton of time playing that one too! He actually broke the stock part getting it off (find a shop manual for your car if you’re afraid of this). But once the grip was removed he was relieved to find the joystick fit perfectly. The two molded plastic halves of the joystick screw together. To join them with the shifting level he used epoxy putty.

The momentary push switch for that thumb button is still in there. But it doesn’t look like he hooked it up to anything. If we were to give this one a try we’d have to find some use for it. Got any suggestions? Let us know in the comments.

3D Printed Bike Shifter

Shifter

[Rich] is embarking on a fairly long bike trip in a few weeks – Seattle to Portland – and thought including some 3D printed gear on his ride would be a fun endeavor. His first idea was a printed belt drive, but the more he looked at that idea the less realistic it seemed. He finally hit upon the idea of creating a 3D printed bike shifter, and after an afternoon of engineering and printing, the shifter ended up working very well.

[Rich]’s shifter is actually a friction shifter. Instead of ‘clicking’ into position, this type moves the derailleur gradually. It’s much more tolerant of slight misalignment, and most touring bikes – the type that would embark on long journeys along the coast of the Pacific northwest – have these types of shifters.

Total printing time was about one and a half hours, and was attached to [Rich]’s bike with off-the-shelf hardware. He’s already put about 150 miles on his custom designed shifter with no signs of failure.

Building A 70-foot Sailboat In Oklahoma

July 5, 2013 by Brian Benchoff 2 Comments

Call it a retirement plan, a hobby, or a beautiful expression of a mental imbalance, but [Doug and Kay Jackson] of Tulsa, OK are building a seventy-four foot steel sailboat in their backyard.

For the last few years, the couple has been working on the SV Seeker, a motor sail junk, since late 2011. They have a wonderful build log, but they’ve also gone the extra mile and documented the entire build process on video. Their YouTube channel is one of the best subscriptions you can have on the site, constantly updated with new portions of the build.

Yes, building an oceangoing ship in a landlocked state may seem like an ill-informed idea, but Tulsa, OK is the home of the port of Catoosa, about 400 miles and 20 locks from the Mississippi river, then another 600 miles to the Gulf of Mexico and the open ocean.

Below you can find some of the highlights of [Doug] and [Kay] fabricating the prop for their ship. First, a pattern was created with a CNC machine, then a mold was made to cast each blade in brass. It’s an impressive bit of work putting all these tools together, and you really get a sense of the challenge of building something this big.

Packing A Jeep Wrangler Full Of Hacks

July 5, 2013 by Mike Szczys 66 Comments

Picking just one image to show off all of the hacks done on this Jeep Wrangler is a tough order. We decided to go with this custom ceiling console as it features the most work done in a confined area.

Give the video walk-around a bit of time before you decide it’s not for you. [Eddie Zarick] spends the first moments touting his “Oakley” branding of the vehicle in decals, emblems, embroidered seats, zipper pulls, and more. But after that you’ll get a look at the pressurized water system we previously saw. Pull open the back gate and there’s a nice cargo cover he built that includes a cubby hole which stores the soft sides when he wants to take the top off. There are several other interesting touches, like the police radar spoofer that he uses to scare the crap out of speeders. Ha!

The ceiling console we mentioned earlier was completely custom-built. It includes a CB, scanner, HAM, and seven-inch Android tablet. There is also a set of push buttons which control the various bells and whistles; well, spotlights and inverter actually. Just add a commode and he’s ready to live out of his car.

Google Science Fair Finalist Explains Squid-inspired Underwater Propulsion

June 30, 2013 by Mike Szczys 15 Comments

Meet [Alex Spiride]. He’s one of the fifteen finalists of the 2013 Google Science Fair. A native of Plano, Texas, [Alex] entered his squid-inspired underwater propulsion system in the 13-14 year old category.

The red cylinder shown in the image inlay is his test rig. It is covered well on his project site linked above. You just need to click around the different pages using the navigation tiles in the upper right to get the whole picture. The propulsion module uses water sprayed out the nozzle to push the enclosure forward. The hull is made of PVC, with a bladder inside which is connected to the nozzle. The bladder is full of water, but the cavity between it and the hull is full of air. Notice the plastic hose which is used to inject pressurized air, squeezing the bladder to propel the water out the nozzle. Pretty neat huh?

We think [Alex’s] work stands on its own. But we can’t help thinking what the next iteration could look like. We wonder what would happen if you wrapped that bladder in muscle wire? Would it be strong enough to squeeze the bladder?

You can see all fifteen finalists at the GSF announcement page. Just don’t be surprised if you see some of those other projects on our front page in the coming days.

Hackers In Africa Are Building Their Own Aircraft

June 27, 2013 by Mike Szczys 78 Comments

hacked-heli

While you’re trying to come up with an idea for your next project this guy’s been building his own helicopter from whatever parts he can find. He’s just one of the aeronautical hackers featured in a story in the Daily Mail. The article’s narrative leaves us with many questions, but there’s enough info to make it worth a look.

In addition to the heli seen above there are also a couple of airplane builds to gawk at. Africa has already produced a couple of very ingenious hacks like [William Kamkwamba’s] projects which improved his village infrastructure. He gained enough notice from his work to land a scholarship to continue his education and that opportunity has also been afforded the creators of these aircraft.

At first we figured this helicopter project was possible because of lack of air traffic regulation in this part of the world. That’s not the case as [Onesmus Mwangi] — who makes his living as a farmhand — has been forbidden to fly the craft by local police. There may be another opportunity for him to fly later in life. He’s received funding to study aircraft maintenance abroad.+

Unfortunately we couldn’t find any video of this thing in action. If that’s unacceptable to you try getting your fix from this human-sized octocopter.

[Thanks Brandon]
