Adventures In Power Outage Hacking

The best type of power outage is no power outage, but they will inevitably happen. When they do, a hacker with a house full of stuff and a head full of ideas is often the person of the hour. Or the day, or perhaps the week, should the outage last long past the fun little adventure phase and become a nuisance or even an outright emergency.

Such was the position that [FFcossag] found himself in at the beginning of January, when a freak storm knocked out power to his community on a remote island in the middle of the Baltic Sea. [FFcossag] documented his attempts to survive the eight-day outage in vlog form, and although each entry is fairly long, there’s a lot to be learned from his ordeal. His main asset was a wood cook stove in the basement of the house, which served as his heat source. He used a car radiator and a small water pump to get some heat upstairs – a battery bank provided the power for that, at least for a while. The system evolved over the outage and became surprisingly good at keeping the upstairs warm.

The power eventually came back on, but to add insult to injury, almost as soon as it did, the ground-source heat pump in the house went on the fritz. A little sleuthing revealed an open power resistor in the heat pump control panel, but without a replacement on hand, [FFcossag] improvised. Parts from a 30-year-old TV transmitter were close at hand, including a nice handful of power resistors. A small parallel network gave the correct value and the heat pump came back online.

All in all, it was a long, cold week for [FFcossag], but he probably fared better than his neighbors. Want to be as prepared for your next outage? Check out [Jenny]’s comprehensive guide.

Need a Night-Light?

[Scott] created an LED candle in preparation for the big mac daddy storm (storms?) coming through.  Like millions of other people in Florida, he was stuck at home with his roommates when an oncoming hurricane headed their way.  Worrying about blundering about in the dark when the power inevitably went out, they set off to gather up all of the candles they had lying around.  Realizing the monstrous pile of candles and matches looked more and more like a death wish, the decision was made to create a makeshift light out of what components they had on hand.  Now, not having access to any outside sources for parts means that you are going to have a bare bones model.

That being said, this straightforward light only takes a couple of seconds to put together.  Jury rig a couple of AA or AAA batteries up, then slap on a resistor, LED, and jumper to get that sucker running.  Wrap electrical tape around the whole thing, or even try duct tape, whatever gets the job done.  A little paper hat on top of it will diffuse the light and bada bing, bada boom, you’re all done.  Generally though, soldering directly onto a battery is not a wise idea.  So, if you want to get fancy, perhaps a better alternative is to have a battery casing as shown below.

This LED candle is a clear option if your home isn’t a micro warehouse for electronic components (apparently it is frowned upon to clog up your garage for projects), and you have limited time.  However, if you have a number of extra minutes lying around before your windows blow in, see if you can top the brightest flashlight ever made (thus far).  Continue reading “Need a Night-Light?”

Cheap and Easy Emergency Butane Stove

Homemade stoves are a very popular hack, you can find a zillion videos on YouTube, mostly on alcohol stoves, and they work great. Less common are butane fueled stoves, but [Thomas Kim] has uploaded a video on a super easy and cheap butane stove.

Like many other DIY stoves, the body is a soda aluminum can. After sealing the top side with aluminum foil, you just need to drill some holes in it. Other necessary components are a metal tube and a syringe needle that acts as flow regulator. [Thomas Kim] makes an interesting fixture that is attached to the can and lets you control the pressure on the can valve and adjust the flame of the stove via a couple of screws.

The stove works great. It is a nice and simple project if you want to start experimenting with these stoves. Safety is important of course, working ventilated area and protect the butane source from heat (in this case the feed tube keeps it away from the burner). Some other projects you may find interesting are this easy rocket stove, or  even this project to make your own briquettes from waste materials. Enjoy and stay safe.

Retrotechtacular: Hacking Mother Nature’s North Temperate Regions

…because they’ll tickle your insides! Seriously, don’t eat them if you happen to parachute alone into wilderness and must survive without firearms or equipment like our protagonist here. This 1955 US Navy-produced gem of a training film will show you how to recognize, procure, and prepare many kinds of nutritious plant, insect, and animal life commonly found between 45° and 70° north latitude.

While you hone your large game hunting skills, you can tide yourself over with all kinds of things that will just sit there ready to be plucked for your nourishment: many berries and fruits, nuts, moss, lichens, and the inner bark of several kinds of trees is edible. Sate your taste for savory with grubs, termites, or grasshoppers. When in doubt, eat what the birds and small animals are eating, but stay away from mushrooms. It’s too hard to distinguish the poisonous varieties.

Many edible things are found in and around bodies of water. Game such as deer, ducks, and birds are attracted to water and make their homes near it. Various kinds of traps made from twigs and vegetation will outwit rabbits and squirrels. You can fashion a bow and arrow in order to kill large quadrupeds like deer, elk, and ram. It’s best to aim for the head, neck, or just behind the shoulders as these are the most vulnerable areas.

Once you have killed a large animal, prepare it for cooking by draining its blood and removing its entrails. There are many ways to cook your spoils of survival, and most of them involve cutting the meat into small pieces first. Hopefully, you have some basic tools for starting fires.
