This is a battery operated cat door that unlocks (going inside) by reading the cat’s microchip. Our cat was chipped at our shelter for around $10, but commercial vets are also able to do it for a bit more. No need to worry about lost collar keys, or magnets. Keeps out unprogrammed animals. The door also has the standard four-setting mechanical overide locking feature of: in-out, in only, out only, locked. If your cat is not chipped, you can also use an RFID collar key (not included).
We previously had a magnetically keyed cat door, but you then have the choice of using a safety collar and losing the (not cheap) key every now and then, or using a non-safety collar and risking the cat strangling itself.
Raccoons eventually defeated our magnetically keyed door. They haven’t defeated this one (yet), although the mechanical parts of the latching action are similar.
The uber American dream is to build your own comfy place on the edge of wilderness with your own hands. The attraction of this self-reliance is the chance to rewind civilization personally, to start over and do it your way. To own your own progress. Thoreau wrote the prime document of lifestyle self-reliance in his shed at Walden pond, an hour’s walk away from his home. Walden is still worth reading as a how-to and why-to book. Yet as the world’s wilderness shrinks, each generation seeks the wild further afield in order to retell the story of sprouting kernel of humanity in a small homestead.
There’s a lot to be learned from the few diehards who have homesteaded far off the grid in modern times, and who have written honestly about the practicalities of this adventure. I found three recent accounts to be most helpful. Listening to them you get to see how much of a subsidy civilization gives us, and how challenging it is to recreate it in even a small measure.
In An Island To Oneself, Tom Neale took over an uninhabited island in the Pacific in the 1950s and constructed a beach shack for his solitary home. He’s a sort of Robinson Crusoe, or Cast Away, for real. He voluntarily lived alone, separated from the nearest human by hundreds of miles of open sea. He had to be his own contractor, gardener, shipbuilder, fisherman, and doctor. The amount of household stuff he recreated from scratch is amazing. Neale had a lot of leisure as a full-time beach bum, but it’s a surprise how constantly he worked, and how thoroughly he had to prepare for everything. His account supplies great details about the reality of living on a deserted island. In a place like his the littlest mistakes could be fatal. His journal is a page turner with one small upset after another. It was no day at the beach.
In a parallel world up in the cold wilds of Alaska, Dick Proenneke flew to a remote lake and built himself a log cabin to live year-round alone among the snow, bears, and blueberries. This achievement is not uncommon for Alaska. What makes his account in One Man’s Wilderness special and useful is that Proenneke thoroughly documented his work in 16mm film movies, photos, and diaries. From his meticulously vivid accounts you get a clear and exact recipe for what it takes to chop trees with an axe, peel them by hand, and erect an airtight cabin. And then to heat it all winter in minus 30 degrees. Proenneke complicated his chores by filming and photographing himself the whole time while doing them, no easy feat with bulky, balky film movie cameras of the 1970s. While his “video” clips are fascinating, I found his journal far more helpful, more impressive, and more inspirational. One Man’s Wilderness is a great account of how to build a tidy cabin from logs you cut and hew, and keep warm and content in the northern wilderness.
Somewhat related to the Alaska romance is the story of Sylvan Hart, who called himself the last mountain man. In the 1960s and 70s Hart homesteaded in a remote part of Idaho. He lived near a road, and had neighbors and mail delivery, but he spent a lot of time making his own tools, and practicing what are now called primitive survival skills. He mined copper, made metal, forged iron, made his own guns, and hunted bear for food and clothing. In other words he was trying to bootstrap civilization as much as he could. His story, written by a sympathetic journalist in the book The Last Mountain Man, gives a somewhat romantic picture of Hart’s life, but even this dramatic view will quell most fantasies with how bootstrapping it is.
Yes, you can build a home in the wilderness using only hand tools, but as all each of these stories make clear, self reliance is relative. Thoreau went to town to do his laundry, Neale brought a boatload of supplies with him, and Proenneke in Alaska had the bulk of his food flown in every month. The larger lesson from these books, and the reason they are cool tools, is that every small step we take toward self reliance is rewarded with heaps of wholeness, self-knowledge, and personal clarity. These books will give you confidence and tips on taking your own small steps toward doing things yourself.
An Island to Oneself
1966 (1990), 255 pages
Available from Amazon
On August 4, 1953 — ten months after I had landed — I welcomed my first visitors.
It was unexpected because I had long since stopped wondering whether one day I would wake up to discover a strange yacht or schooner anchored in the lagoon. I had become so engrossed with my life on Suvarov that I rarely gave a thought to the outside world.
They were very happy days. I was never lonely, though now and again I would walk along the reef wishing somebody could be with me — not because I wanted company but just because all this beauty seemed too perfect to keep to myself.
Fishing in the shallows with a single pronged spear.
The evening’s haul. I was never short of fish.
Of course, I had heard of this great lagoon, with its coral reef stretching nearly fifty miles in circumference, but I had never been there, for it was off the trade routes, and shipping rarely passed that way.
Because its reef is submerged at high tide — leaving only a line of writhing white foam to warn the navigator of its perils — Suvarov, however, is clearly marked on all maps. Yet Suvarov is not the name of an island, but of an atoll, and the small islets inside the lagoon each have their own names. The islets vary in size from Anchorage, the largest, which is half a mile long, to One Tree Island, the smallest, which is merely a mushroom of coral. The atoll lies in the centre of the Pacific, five hundred and thirteen miles north of Rarotonga, and the nearest inhabited island is Manihiki, two hundred miles distant.
Morning and evening from that moment on I scattered the split uto nuts on the square of ground where the run was to be built, and then banged lustily on the old iron crowbar made from the transmission shaft of a Model T Ford I had acquired in a Raro junkyard. The result was really extraordinary. Up till now I had spent weeks unsuccessfully trying to cajole the fowls into a regular feeding tie. Now, within a week, they were recognizing the familiar sound of the beaten crowbar, and cam running as fast as they could, determined not to miss a good feed. They brought all sorts of surprises with them too — in the shape of at least two clutches of chicks which I had no idea even existed. Although this achievement did not immediately solve my egg-collecting problems, at least I was able to keep track of the island’s hen population, and now I started building the chicken run in earnest.
I knew the portents only too well (that trite old phrase about the calm before the storm) and strode back to the shack. There was no immediate hurry — but equally there was no doubt that serious trouble was on the way. Before doing anything else, I checked my survival cache of tools, making sure my extra matches in their sealed tin were dry, and then took the box over to the “burial hole” in the outhouse. Next I lit a good fire on my brick hearth, and while it was burning, went out with my spear for a concentrated hour of fishing. It seemed provident to lay in some emergency rations, for there was no telling with a big storm; it could last a few hours or a few days.
I had plenty of cooked uto, but I foraged around for a couple of dozen more, which I cooked, and then I laid out double rations for the fowls. Next — as the first puffs of wind ruffled the palms — I inspected the garden for any ripe fruit which would be mercilessly blown off the plants when the inevitable storm broke.
I had sufficient uto to withstand a siege of several days — and in a way it was rather like preparing for a siege against an implacable foe. In the outhouse I had a plentiful supply of wood, and in the kai room a good stock of arrowroot, plenty of fresh vegetables, including yams, cucumbers, tomatoes, spinach and onions. A dozen drinking nuts, a couple of ripe breadfruit and a stem of bananas completed my emergency rations.
By mid-afternoon gigantic seas were visible breaking all along the reef to the north, and before sunset, when the storm was beginning to reach its height, seas more huge than I had ever seen before began breaking right across the half-mile width of the entrance to the passage.

Learn to use an axe and respect it and you can’t help but love it. Abuse one and it will wear your hands raw and open your foot like an overcooked sausage. Each blade was nursed to a perfect edge, and the keenness of its bright arc made my strokes more accurate and more deliberate. No sloppy moves with that deadly beauty! Before I started on a tree I carefully cleared obstructions that might tangle in the backswing. It was fun planning where each should fall, and notching it for direction. Snuck! Snuck! The ax made a solid sound as it bit deeply into the white wood.
Anyone living alone has to get things down to a system — know where things are and what the next move is going to be. Chores are easier if forethought is given to them and they are looked upon as little pleasures to perform instead of inconveniences that steal time and try the patience.
I included in the first trip a .30-06 converted Army Springfield, a box of cartridges, a .357 magnum pistol with cartridge belt and holster, the backboard, the camera gear (8mm movie and 35mm reflex), cartons of film, the foodstuffs (oatmeal, powdered milk, flour, salt, pepper, sugar, honey, rice, onions, baking soda, dehydrated potatoes, dried fruit, a few tins of butter, half a slab of bacon), and a jar of Mary Alsworth’s ageless sourdough starter.
The second pile consisted of binoculars, spotting scope, tripod, a double-bitted axe, fishing gear, a sleeping bag, packages of seeds, A Field Guide to Western Birds, my ten-inch pack, and the clothing. More bulk than weight.
The third pile held the hand tools such as wood augers, files, chisels, drawknife, saws, saw set, honing stone, vise grips, screwdrivers, adze, plumb bob and line, string level, square, chalk, chalk line, and carpenter pencils; a galvanized pail containing such things as masking tape, nails, sheet metal screws, haywire, clothesline, needles and thread, wooden matches, a magnifying glass, and various repair items; a bag of plaster of Paris; and some oakum.
It is always interesting to see what a fish has been eating. Several times I have found mice in the stomachs of lake trout and arctic char. Now how does a mouse get himself into a jackpot like that? Does he fall by accident, or does he venture for a swim? tough to be a mouse in this country.
It is important to put the notch on the underside of a log and fit it down over the top of the one beneath. If you notch the topside, raid will run into it instead of dripping past in a shingle effect. Water settling into the notches can cause problems.
Had my first building inspector at the job. A gray jay, affectionately known as camp robber, came in his drab uniform of gray and white and black to look things over from his perch on a branch end. The way he kept tilting his head and making those mewing sounds, I’d say he was being downright critical.
1) These simple hand tools will challenge anyone’s self-reliance. 2) Notice how the notches fit snugly over the tops of the logs below them, as if fused.
* 1) Dick readies the roof poles for installation. 2) With the poles in place, the slots between the pole ends under the eaves need to be filled in. These fillers should be called “squirrel frustraters.”
Wood to saw and split everyday. Got to keep up my payments at the Firewood Trust if I want to stay warm this winter. No real problem at all. Some folks had led me to believe it would be an everlasting job — cut wood all day to keep warm all night.
The Last of the Mountain Men
1969, 160 pages
Available from Amazon
As a young man, dismayed by the destruction of the final frontiers, Sylvan Hart recanted civilization and marched off into this Idaho fastness armed with a few staples, an ax, a rifle, and a master’s degree in engineering. There, in the last wilderness, where one winter’s snow might fall into another’s before a visitor came, he became the last of the Mountain Men. Son to be known as Buckskin Bill, he fashioned his own clothes of deerskin. He constructed adobe-covered building with hand-hewn timbers. He mined copper, smelted it, refined it, and made utensils. He even made his own flintlock rifles, boring them on an ingenious handmade machines, to “save the bother of sore-bought ammunition.” To pay for infrequent trips to Burgdorf (pop. 6, in winter 0), where he purchased only powder, books, and Darjeeling tea, he panned gold.
* Sylvan’s pole bridge, pinned precariously to the sheer face of a cliff high above the roiling River of No Return, constitutes the only path to the outside world.
Tree houses are impractically romantic. There is no one book on how to make this recurring romance as practical as possible, but these two books by Peter Nelson contain the best suggestions and useful advice for building a real live-in tree house I’ve seen so far. The Treehouse Book has lots of fabulous examples in the US and a few chapters on how-to. His follow-up book, New Treehouses of the World, gathers inspirational examples from Thailand, New Zealand and other spots with tree-house culture, and has a short chapter on new tree-house technology. Main thing to remember when building a tree house is that trees move, over minutes and years. It’s closer to building a boat in the air. That’s why there’s plenty ideas in these books for any small house, even those not arboreal.

Trees in the northwest grow surprising quickly, so I prefer a GL (Garnier Limb) with a longer stem, the part of the GL that sticks out from the tree. While trees grow taller only at their tips, they grow in girth all long their length. As a tree puts on rings it envelops the GL, making the artificial limb even stronger. The tree will eventually push a beam out along the stem of the GL (the reason I prefer a longer stem) in much the same way the tree’s roots might lift a heavy concrete sidewalk.
A “heavy limb,” also designed by Greewood, holds up a bucket-style bracket attached to a large glue-laminated beam. There are numerous styles of artificial limbs, or tree anchor bolts (TABs).
* An elegant platform takes shape around the old-growth Sitka spruce. Occasionally a tree will resist a building project, but this magnificent specimen remained calm and allowed us to proceed without protest.
This tool literally saved me thousands of dollars and incalculable emotional stress. Watercop attaches to the water main on your house and is triggered by remote RF water sensors that can be placed anywhere. When triggered, it shuts off the main and stops all water flowing into the house.
I installed the Watercop 5 years ago with remote sensors in 4 locations and it sat silently, doing absolutely nothing for all that time. A few weeks ago we got back from a week long vacation and immediately discovered that there was no water coming through our faucets. My first thought was that the Watercop had experienced a power fault and failed closed.
I went down to the basement and, in fact, the Watercop was closed. I turned it back on and heard a gusher from our furnace room. You can imagine my shock when I ran into the furnace room and discovered that the floor of our 15-year-old hot water heater had burst and the Watercop sensor in the room was submerged.
I don’t even want to contemplate what would have happened during that week if there had been no automatic shutoff on the main. The damage to our house and personal possessions, along with the inevitable mold, would have been a disaster.
Not only did it work flawlessly, but you can qualify for an insurance discount if you you have it installed by a licensed plumber (you can install it yourself, but it does require decent plumbing skills). As far as setup, you can place the sensors anywhere. The only downsides I have found is that it is not cheap, you have to replace the batteries annually, and it runs on A/C power meaning that when the power fails so does the device.
Despite these few drawbacks, I can not recommend the WaterCop highly enough. This is, without a doubt, the most valuable tool I have ever purchased.
I’ve used various powerline adapters for several years. They now can go up to 500 megabits per second, but 85 or 200 will be cheaper. I currently use TrendNet Powerline routers.
Why not use wifi? The bands are becoming crowded. You can try to use 5Ghz N routers, and they help, but if all your other devices – your phone, iPod, Kindle all have to use the 2.4GHz wifi, it can get congested. Wireless USB peripherals and Bluetooth also use the same band. Not everything supports the 5GHz band, so your laptop might not
work, or you will need a special card or adapter for your desktop. Then there’s securing things and getting the network password right. And in apartments, every one of your neighbors is using the same band.
Powerline adapters need passwords, but they are between the adapters and you only have to use the setup utility once. They are basically ethernet bridges. I have my cable router plugged in where the cable comes in and the signal is best, then have my wifi and powerline adapters plugged into that router (it has 4 ports). I’ve not had any problem streaming or even sending files between computers. I have several 200Mb/s refurbished models and they work well for that, but I have gigabit switches at my central computer “nerve center”. The powerline adapters also make printers a lot easier to setup. I have a Brother printer that is finicky about Wifi: it can attach USB, Ethernet, or Wifi, but even after typing in the correct information when attached with one of these other methods it often “fails to associate”. Instead, I just use the powerline adapter, and instantly it is on ethernet with no headaches.
Well, there is one. A powerline adapter uses up an electrical socket, which is where the “Liberator” comes in. Basically, a 3 pronged pass-through extension cord. The short plug-depth seems to play well with the powerline adapter, and the extension is hefty enough for my laser printer. The Liberators also work well with power strips or even to go sideways when space is at a premium.
There are a few rare cases where powerline adapters have problems. One is if there is something extremely electrically noisy on the same branch (and if it isn’t noisy you need the passwords to prevent your neighbors from snooping). This usually involves some huge motor, arc welding, or other industrial process involving intermittent high current. Another thing is if there are any ground loops or ifhot and ground get swapped by adapters or bad wiring. Also it helps to avoid circuits with dimmers and microwaves, though I’ve only had the problem when some part of the house wiring was wrong enough to show bars on my old CRT TV when the microwave was on. The powerline signal cannot pass through the large (utility pole) transformers. There is a length limit, but I haven’t been in a position to see how fast the signal goes at hundreds or thousands of feet.
If wifi works and the total cost of adapters and such is low, it might be a be a better solution, but for reasonable distances where there is lots of interference or if you only have ethernet, nothing beats powerline adapters.
I have a small amount of stuff that I want within easy reach at night, including my cellphone, lip balm, and a small bottle of water. I was considering housing it in a bedside caddy or organizer, but wasn’t thrilled by the idea of buying a uni-tasking extra product just for that one purpose. Searching for a better solution, I stumbled across Neat Sheets sheet sets from a company called Everest Luxury Linens. These sheets come with sewn-on side pockets on the fitted sheets which serve as convenient repositories for whatever you want within reach while you’re in bed.
Neat Sheets also have sewn-on tags at the foot of the sheet, to (as the company says on its site) help you get the right corner of the sheet on the right corner of the mattress, every time. I hesitated to buy Neat Sheets, because the site had a slightly gimmicky infomercial-style vibe. But a few months ago I did buy them, and they are terrific. They are exactly what’s described on the site, and I find they make my life just a tiny bit easier every single day. As a minimalist and a fan of good design, I’m really pleased.

Last year I was walking through IKEA when I saw this strange little solar-powered goosenecked lamp in the lighting section. Intrigued, I bought it and took it home to try out.
I love it. The bulb is nice and bright, perfect as a reading lamp. And the battery/solar panel unit pops out, so you can leave it by a window or on your car’s dashboard, and it will fully charge while you’re at work. Since then, I’ve gone back and bought a second one. I always have a battery pack charging on a windowsill, and I always have light for my latest book.
Oh, and we brought one of the lamps on a camping trip. It was really handy there too. I left it on one night as a sort of night light for our daughter, and in the morning, it was still shining, just not as brightly. This is one of the few solar-powered gadgets I’ve encountered that actually works as promised. A nice additional bonus, for every lamp sold, IKEA donates one to a child in a country with unreliable electricity.
The hexayurt is an update on Buckminster Fuller’s geodesic dome and is a sturdy, affordable, easy-to-build temporary shelter. The geometry has been adjusted slightly to make it easier to build domes from materials like plywood, insulation, plastic, cardboard and more. The hexayurts are made from only one kind of triangle: an 8′ x 8′ isosceles triangle, rather than the strangely-shaped triangles which are standard for Fuller-style geodesic domes. They are not strictly geodesic, either, but it doesn’t seem to matter much in practice. The slightly stiff, angular lines look a lot like any other dome.
The most common place to see hexayurts is at Burning Man. The first one was built there in 2003, and was only a little bigger than a tent. There now range in size from 50 to nearly 500 square feet. A typical year at Burning Man will see a hundred or so of the silver huts lined up on the playa.
The design is public domain and build-it-yourself. People using the shelter for Burning Man usually buy the materials (about $300) ahead of time, including mail ordering the hard-to-find extra wide tape which is used to hold the shelter together. It takes about a day’s worth of effort to cut out the roof pieces, playa-proof the edges and do a test assembly. Putting the hexayurt together on the playa typically takes a small group of people about two hours and can be a struggle if there is wind or a dust storm which coats all the pieces in a fine layer of tape-defeating dust.
The joy of the thing is a building which stays relatively cool in the desert. The shiny surface of the hexayurt reflects away a lot of the sun’s heat, and a mix of pump sprays, swamp coolers and even the occasional air conditioner make the inside quite habitable even in the middle of the day when tents are far too hot for comfort. There are lots of plans and instructional videos on the Hexayurt web site, and handy people seem to have little difficulty putting them up.
A few simpler units, made from plywood, have been tested by local charities in Sri Lanka and Haiti. The jury is still out on whether this shelter will be useful beyond recreational use in the desert, but field trials are underway.
This terrific product is perfect for dealing with minor stubborn behavior in your cat. I didn’t like our cat going up on the counter behind our kitchen sink to look out the window, but every time I went outside, there she was laughing at me. I tried many different deterrents, but she was like the Borg from Star Trek. She would just adapt. SSSCat solved the problem.
SSSCat is a can of compressed air (like for cleaning the dust out of your keyboard), but with a motion sensor that sprays when the cat gets near. It doesn’t harm or hurt the cat in any way, but it does condition them to avoid the area where the SSSCat has been.
We’ve also used it outside of our bedroom door to prevent the cat from persistently meowing and jumping up at the door in the wee hours of the morning.
The can of compressed air the unit comes with is about half the capacity of the cans you get for dusting keyboards. After it ran out, I found that I could use the keyboard duster cans. Just popped the trigger off the keyboard duster and attached the SSSCat nozzle.
Jean Luc Picard could have used this against the Borg. They never would have figured it out.

I’ve been using the FireDragon for the past five years to quickly and efficiently get my woodstove burning. It allows me to get a fire started using a minimal amount of tinder and kindling, and without any other firestarters. This is one of those simple, good ideas. You blow into the FireDragon to shoot a directed, bellows-like blast of air into your fire, creating a supercharging effect. This helps get larger chunks of wood to ignite and burn steadily when lighting a fire or adding a new log to a fire that isn’t burning well, and it can return a smoldering fire to blazes with a few puffs.
It’s basically a 3-foot long steel tube with a brass mouthpiece (that makes me think of a flattened trombone mouthpiece) and a forked end that can serve as a fire poker, log re-arranger, and coal raker. The manufacturer says they got the idea from Civil War soldiers that would take the barrels off their rifles and blow through them to fan their campfires.
Now I find I want the FireDragon any time I’m around a fire, so it goes along camping. It is plenty sturdy. No moving parts, and easy to use.
