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.
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.

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!

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.

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.
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.

For many of our parents, grandparents, and great grandparents, the things we consider hacking, making, and doing weren’t just for fun. They were important skills that could help one survive. This week [Dino] shows us something his dad taught him: waterproof fire starters. The trick is paraffin wax. [Dino] starts by melting down some wax in a pot. He then dips strips of newspaper in the liquid wax. Several strike anywhere matches also get the wax treatment, are then placed on the newspaper. The newspaper and matches are rolled up into a tight bundle, which is itself dipped in wax several times.
The resulting small bundle of waxed newspaper and matches is safe and easy to carry in pocket or backpack. It also becomes the perfect wet fire starter. The “newspaper shell” is torn off into strips of waxed paper, which burns slowly and allows the tinder and wood to catch. [Dino] demonstrates his pioneering skills by starting a fire at the end of the video. When the inevitable zombie apocalypse hits, we definitely want [Dino] at the Hackaday compound.
