Something’s Brewing Up In The Woods – And It Looks Stunning

Caffeine fuels the hacker, and there are plenty of options to get it into your system, from guzzling energy drinks to chewing instant coffee pellets. But let’s take a nice cup of coffee as input source, which itself can be prepared in many ways using all kinds of techniques. In its simplest form, you won’t need any fancy equipment or even electricity, just heat up some water over a fire and add your ground beans to it. This comes in handy if you’re camping out in the woods or find yourself in a post-apocalyptic world, and in case you still prefer a stylish coffee maker in such a situation — why let an apocalypse ruin having nice things? — you’re in luck, because [Andreas Herz] designed this nifty looking off-the-grid coffee maker.

The design somewhat resembles a certain high-end precision coffee maker that even fictional billionaires approve of, which [Andreas] created in Fusion 360 and is available online. The device base is made from brass, wood, and silicone he cast from a 3D printed mold, while the glass and ceramic parts — i.e. the water tank and coffee pot — are simply store bought. [Andreas] opted for fuel gel as heat source, which burns under a copper coil that acts as heat exchanger and starts the actual brewing process. It took him a few attempts to get it right, and in the end, a coat of black exhaust paint did the trick to get the temperatures high enough.

This may not be the fastest coffee maker, as you will see in the video after the break, but choosing a different fuel source might fix that — [Andreas] just went the safe(r) way by using fuel gel here. But hey, why rush things when you’re camping or having a cozy time in a cabin anyway. Now all you need is the right blend, maybe even your own, made with a camp stove coffee roaster. Of course, in case of an actual apocalypse, you may not have easy access to a CNC router or 3D printer, but then there’s always the option to build an espresso machine from salvaged motorcycle parts.

A French Press You Can Take Out Camping

There’s many a hacker that considers coffee a necessary fuel, without which, little work can be achieved. This applies whether in the office or traipsing around in the great outdoors. For the latter situation, [Poehls05] developed a robust French press that’s well suited to field use.

Typically, a French press consists of a plunger assembly which moves within a glass vessel. This is fragile and unwieldy for throwing in a backpack. Instead, in this design, the plunger assembly is harvested from an existing press and repurposed to fit within a sturdy Nalgene water bottle, designed specifically for overlanding.

The modifications involve cutting the existing press plate into three slices, and reassembling with hinges so it may fold. The plunger rod is then modified to make it possible to tilt the press plate relative to the rod. These modifications allow the plunger to be slid into the narrower neck of the Nalgene water bottle, and also enable the plunger rod to work with the original screw-down lid. In this configuration, the bottle is no longer water tight, but can be converted to normal use by swapping a regular lid back on top.

With the changes in place, the plastic bottle can easily be used in the same manner as a regular French press. Simply fill with hot water, allow the grounds to steep, and then press and pour. It’s a great way to make high-quality coffee in the wilderness, and one that may prove popular with hackers who don’t wish to give up the finer things when out and about. We’ve also featured tricks to make the most of hotel coffee, too.

Want A Leak-Proof Camper? Better Fire Up The 3D Printer Now.

Ah, the great outdoors.  Rejuvenating air rife with mosquitoes and other nasties, and spending some time hanging out in the woods sleeping in a 3D printed camper. Wait– what was that last one again?

Yep, it’s exactly what it sounds like. A Canadian team headed by [Randy Janes] of Wave of the Future 3D, printed a camper at [Create Cafe] in Saskatoon, Saskatchewan, using high-flow nozzles on one of the largest 3D printers in North America. These layers are 10.3mm thick!!

This trailer is one single printed piece, taking 230 hours — nine and a half days — of straight printing with only a few hangups. Weighing 600lbs and at 13 feet long by six feet wide — approximately 507 cubic feet, this beats the previous record holder for largest single piece indoor print in size by three times over.

Solar Power In A Can!

When spending time camping, people often bring lanterns, flashlights, and the like — you might even bring along a solar charger. Instructables user [bennelson] is combining all your electrical powered needs by cramming solar power into a can.

Already designed to resist the elements, [bennelson] is using a 50cal. ammo can for a portable enclosure. Inside, he’s siliconed a 15AH, 12V lead-acid battery in the centre to maintain balance and to leave room for the wiring and storage. One cardboard mockup later, he laser-cut the top panel from 1/8″ plywood and secured a 20A solar charge controller, a four-in-one socket panel, and two banana plugs on its top face.

[bennelson] is using 12 AWG wire to match the 20A rating of the solar charge controller — including a fuse for safety — and lever lock-nut connectors to resolve some wiring complications. Industrial velcro keeps the top panel in place and easily removed should the need arise. When he’s out camping, he uses an 18V, 1A solar panel to charge, but can still use a DC power adapter to charge from the grid. Check out the full build video after the break!

Camping In A…. Corolla?

A weekend away camping in the wilds can do wonders for one’s sanity, and the joy of spending it in a recently converted camping vehicle adds to the delight. In a twist on the conventional camper, redditor [Gongfucius] and his wife have converted their 2005 Toyota Corolla into the perfect getaway vehicle for two.

To make enough room, the rear seating had to go, and removing it was deceptively easy. [Gongfucius] was able to build and fit a platform peppered with storage hatches that could snap into place and cover the trunk and backseat — covering it with felt for added comfort. A mattress was cut to size out of five inch memory foam and his wife sewed fitted coverings to them. More storage nooks in the trunk keep necessities at hand.

Camp Kitchen Kit For Food On The Go!

Camping and road trips are a heck of a lot of fun, despite lacking many of the creature comforts that come from a house and its amenities. We’re all for fire-cooked meals, but sometimes, you want a cook-top and a sink to make cooking on the go a quick process. What if you could pack up a kitchen into a box and take it with you?

[pointblankjustice]  — opting for overkill — built this for his girlfriend instead of the requested box to simply store camping supplies. Glued and screwed plywood forms the frame, drawers, and lid which was then stained and painted to make for an appealing finish. A simple propane camp stove makes a worthy cook-top.

Obviously, one must include a kitchen sink, so a small bar sink and hose faucet are kept running with a cheap, 12V, 35psi pressure pump from Amazon. A little doughnut magnet keeps the faucet secured when not in use. Spent grey-water drains from a hose into a bucket or into a ditch (don’t worry — [pointblankjustice] uses biodegradable soap!).

As an added bonus, [pointblankjustice] has some under-cabinet lighting and accent lighting to keep things cooking late into the night, with power supplied by an extension cord going to their Jeep’s cigarette lighter outlet — plans to add a built-in battery are pending. There’s also a pair of USB ports to keep one’s phone charged and a bear-shaped bottle opener to keep the good times rolling!

The kit packs up nicely and fits snug in the rear of [pointblankjustice]’s Jeep with enough room for other supplies and a pair of dogs.

For longer hauls out into the wilderness, you might consider bringing a solar power supply unit that literally lasts for days.

Off-Grid Travel — Setting Up A Solar System

When you’re living out of a vehicle, or even just traveling out of one, power quickly becomes a big concern. You need it for lights, to charge your various devices, to run your coffee maker and other appliances, and possibly even to store your food if you’ve got an electric refrigerator. You could do what many RV owners do: rely on campgrounds with electrical hookups plus a couple of car batteries to get you from one campground to the next. But, those campgrounds are pricey and often amount to glorified parking lots. Wouldn’t it be better if you had the freedom to camp anywhere, without having to worry about finding somewhere to plug in?

That’s exactly what we’re going to be covering in this article: off-grid power on the road. There are two major methods for doing this: with a portable gas generator, or with solar. Gas generators have long been the preferred method, as they provide a large amount of power reliably. However, they’re also fairly expensive, cumbersome, noisy, and obviously require that you bring along fuel. Luckily, major advances in solar technology over the past decade have made it very practical to use solar energy as your sole source of electricity on the road.
