I just love DIY ideas like this, don’t you? After all, I wrote an entire book about DIY survival projects, so it only stands to reason that I would, lol.
In any case, the neat thing about this solar tracker is that it doesn’t need any GPS signal or computers to work but, instead, simply “follows” the movement of the sun using small light sensors throughout the day!
Apparently, he got the original idea from this video which includes more details about the build, if interested…
Definitely worth the effort for SHTF if you can manage to get enough solar power to run it all day long. Stick around to the end (at about the 9:00 mark) to see how he adds a variable speed switch to reduce the fan speed and save precious battery power…
Unfortunately, it doesn’t look like this fire starting kit is something you can purchase as a pre-made solution, but you can certainly copy the idea well enough if you’re interested in a wilderness or bug out bag fire starting kit to emulate…
I really do enjoy DIY projects and none more so than projects with hidden compartments, lol. This particular bookshelf has its compartment in the bottom, so you can watch him build the entire project or maybe skip to near the end to see the final assembly and compartment location…
Never know when you might need to make one of these to move something heavy out of the way or to pull a vehicle out of the ditch. That said, I sure am glad they invented the come-a-long power puller because this would take forever, lol…
An underground bunker could be your best asset in many different survival scenarios. It gives you a place to wait out whatever chaos might be going on above-ground and helps ensure you and your family stay safe — even comfortable — no matter what’s happening in the world. Many survivalists dream of having an underground bunker. While it’s not cheap or easy to build one, it is doable. If you’re ever in a situation in which you need a bunker, you’ll be glad you invested the time and money. Here’s our guide for building your underground bunker.
Get a Permit
you start building your bunker, you need to get a permit to ensure you stay on the
right side of the law. Consulting local authorities will also give you crucial information about
such as gas or water pipes, that might be on your property — one of the main
reasons you need a permit. Before you do anything else, research the laws in
your area and take the steps required to make sure your project is legal. You
don’t want to spend a bunch of time planning a bunker, only to find out you
can’t legally do so.
you start building your bunker, you’ll need to have as many details planned out
as you possibly can. However, planning is second nature to a survivalist, who
is always thinking about the future.
Choose a Location
of the first things you need to plan is the location of your bunker. You
probably need at least half an acre to build a decent bunker. Some important
considerations when deciding on a bunker location are:
also need to decide where you want to locate your bunker in relation to your
house. Some people build their bunkers directly underneath their home, which
allows for easy access, but can make it more likely you’ll run into obstacles
like plumbing pipes and electrical equipment. You can also put your bunker
elsewhere on your property and build a tunnel to your home, or erect a small
shed to conceal the entrance.
you’re building a decently sized bunker, you’ll likely want to use some heavy
excavation equipment. You can rent this equipment or hire someone to do your
digging for you. If you’re using heavy machinery, plan for excavation to make
up a significant portion of your budget. Technically, using a shovel is an
option, but that will take much longer unless you’re just building a small
Build Your Structure
got several options when it comes to the structure of your bunker. If you want
to go the quicker and easier route, you can use a premade structure such as a
shipping container. While this is an efficient way to get shelter finished, it will give
you a lot less flexibility in your design. If you do use a shipping container,
make sure you reinforce it, as the design of these containers doesn’t allow
them to take a heavy load on the top and sides. You’ll again need some heavy
machinery to lower the container into the hole.
can also build your structure yourself. While it will take more work and time
to do so, you can customize your shelter to your precise specifications.
significant consideration when planning your structure is what material to use
for your floor, walls and ceiling. Wood is not the best choice for a bunker.
While it’s cheap, sturdy and easy to work with, it won’t last as long as many
other materials. Untreated wood is susceptible to weathering and rotting. Even
treated wood will eventually break down and may suffer from insect infestation.
better option is metal. Welding thick metal sheets together and supporting them
with tube steel makes for a sturdy, moisture-resistance structure. The downside
to using metal is that it’s more expensive than some other options.
you want a more affordable but still sturdy option, consider using bricks or
cinderblocks. They last a long time and are relatively easy to install. Bricks
will also provide excellent insulation.
excellent option is concrete. It’s long-lasting, sturdy, affordable and
relatively easy to work with.
careful when choosing the materials you’ll work with. Even small items like the
fasteners you select have an impact on your structure’s durability and safety.
Bolts, for example, can typically withstand more
pressure than screws or nails.
Build Entrances and Exits
How you get into and out of your bunker is another vital
consideration. Many survivalists opt to create a passage from their house to
their shelter so they can get underground without going outside. You can also
create an outdoor entrance and conceal it by building a small shed over top of
it. You should always have at least two ways in and out in case one of your
passages gets blocked off.
Ensuring you have correctly supported the passages into your
bunker is essential. Use pillars made from concrete or bricks to keep your
passages sturdy and safe.
Waterproof Your Bunker
building your bunker, do everything you can to ensure moisture doesn’t seep
into it. Using a sturdy metal, concrete or brick structure is vital to keeping
water out, but you may also want to place a waterproof sheet over the top of
your shelter to provide some extra protection from moisture.
Plan for Air Filtration
also need to make sure you have access to fresh air in your bunker, which will
be crucial if you end up needing to shelter there for an extended period. Have at
least two air vents. They’ll keep fresh air flowing in your bunker and help
cool it down during the summer. Also, invest in an air filtration system and
stock up on air filters. You may also want to purchase a gas mask in case you
have to leave your bunker before the outside air is safe to breathe.
Plan for Clean Water
course, you will also need access to water while you’re in the bunker.
While you can store containers of water in your shelter, you’ll run out quickly
if you’re stuck underground for longer than you anticipated.
option is to install a large water tank next to your bunker. Doing so means
you’ll have to do more excavation, but a water tank will provide you with a
significant quantity of water.
a large water tank will eventually run out, though, if you’re in your shelter
for a long time. For this reason, it’s ideal to have a water delivery system
that can replenish itself, in addition to a water tank. You may be able to tap
into the water table from within the shelter. You might need additional permits
if you plan on digging a well in addition to your bunker. If you have running
water nearby, you may be able to install piping to channel it into your bunker.
You could also create a rainwater harvest system that collects water above the
ground and pipes it to you underground. Just make sure you invest in equipment
for filtering the water so you can ensure it’s safe to drink.
Conceal Your Underground Survival Bunker
also need to determine how you’re going to conceal your
you’re finished building it. Your hideout is going to be a lot less useful if
everyone can see where it is. So, how do you hide your bunker?
course, you’ll cover your bunker back up with dirt once you finish building it.
Use the dirt you dug out of the ground, so it blends in with the surrounding
earth. Also, plant fauna that matches the surrounding area. You want to do everything
you can to prevent the space above your bunker from standing out.
mentioned earlier, you can build a small shed to hide an outside entrance to
your shelter. If you have an entry in your house, cover it up with a piece of
furniture or carpet. You can conceal your air vents by planting bushes over
them and hiding them behind rocks.
creative with this step and use what you have to your advantage. The better
disguised your bunker is, the more secure it will be.
also want to make sure your bunker is relatively soundproof. Consider
installing soundproofing materials, such as acoustic foam, to keep any noise
from escaping into the outside world.
Add Access to Electricity
electricity in your bunker is optional, but it can make survival more
manageable and allow you to be as comfortable as possible while spending time
in your hideout.
in mind fuels like propane and kerosene are off-limits. Even if you have a good
ventilation system, it’s dangerous to use these kinds of fuels in an underground
bunker due to the fumes they create.
can connect your bunker to the power grid, but in a real doomsday scenario, you
likely won’t have reliable access to it. You can consider connecting to the
grid as a backup, though, if you like.
best bet for getting power in your bunker is an off-grid renewable energy
system such as solar panels or a small wind turbine. If you have running water
nearby, you may also be able to build a small
water turbine generator. Having a power source can make it a bit more difficult to hide your
bunker, but you could make it look like the system is powering your home, but
also run wiring to your shelter. It would be useful to have a battery system
alongside your renewable generation so you can have a more continuous flow of
if you do include electricity in your bunker plans, make sure you can also
survive down there without it, as your aboveground generation equipment could
Stock Your Bunker With Supplies
Once your bunker is ready to go, what should you store in it?
Everyone’s list will likely look a bit different, but here are some supplies to
you’ll need a supply of nonperishable food items such as canned goods and
dehydrated meals. One positive of keeping your emergency food cache underground
is that it will naturally stay a bit cool. You might also want to dig an extra
room for food storage. Just make sure it stays dry.
supplies:You’ll also need
a first-aid kit that includes essential over-the-counter medications and
emergency medical supplies such as alcohol wipes and bandages. If you need
certain medicines that are specific to you, you might want to keep a supply in
your bunker as well.
ammunition: You might also want some method of self-defense. If you store a gun,
make sure you have an adequate supply of ammunition. Just make sure you don’t
sacrifice too much space you could use for food or medical supplies to make
room for more weapons.
Just because you’re in an emergency, that doesn’t mean you can’t
have some fun while in your bunker. Keeping a positive mindset will be crucial
to your safety and survival, and having some way to entertain yourself can help
you stay upbeat. Store some board games, a deck of cards, books, art supplies,
a musical instrument, video games or whatever else you like to use for
Keep Yourself and Your Family Safe in Any Situation
an underground bunker isn’t easy. With adequate planning and the right
attitude, it is doable and well worth it. It can even be fun. It’s not cheap,
either, but you can do it affordably if you plan and get a bit creative. Just
make sure you never sacrifice safety to cut costs.
Having an underground shelter could be useful to anyone. Doomsday preppers have lots of reasons for wanting one, but they’re also helpful during natural disasters such as tornadoes. Plus, they’re excellent for storing emergency supplies. If you go all-out with your bunker, you might even find yourself wanting to hang out in it.
Have you always wanted a Faraday Cage to protect your sensitive electronics from an EMP, but were afraid of the cost? Well, consider this idea on making your own Faraday cage for about $5 each. And the best part: you can make several of these with the supplies you’ll need! Here’s how…
“Although the EMP literature is scarce, and often contradictory, I found a “recipe” for a Faraday cage that should withhold both types of EMPs, whether natural or man-made. Based on my own research, I’m pretty sure this will work better than a microwave, a galvanized trash can, or some of the other solutions you can find online.
The idea is simple: wrap your devices in alternating layers of insulating and conductive material, then put everything inside a thick ammo box.
Aluminum foil is cheap, you can find cardboard around the house for free, duct tape and packaging tape are also dirt-cheap, so you can make a cheap Faraday cage for less than $5. Now you will spend more than $5 for these supplies, but keep in mind you’ll be able to make several cages for this amount of money. This doesn’t include the ammo can, which you also probably have in your garage…”
The author clearly took this project very seriously, going so far as to angle fins to absorb the most energy of these solar panels. In fact, the author states that he can maintain the internal temperature of the shop at 65 degrees Fahrenheit when the outside temperature is about -20 degrees.. what a difference!
“A solar heating panel is not just a box with a glass front, a black interior, and a pair of openings in the back. Any fool can build such a box – and many have, but very few have managed to heat an entire building with the result.
You already knew that, of course, or you wouldn’t be reading this. I mention it only because you may not have known that you knew, and because I think it’s an important starting point for our discussion.
When I decided to seriously tackle the design of a solar heating panel, I listed seven requirements for a successful design:
The panel must operate efficiently using only the thermal energy it captures – independent of all other energy sources. Diurnal operation
The panel must deliver heat efficiently during the day, and not lose more than an absolute minimum of heat when there is insuficient sunshine to provide any deliverable heat. Season-dependent heating
The panel must deliver maximum heat during winter, and a minimum in summer. Maximum reliability
The panel must have no moving parts to wear out or fail, and must operate dependably in untended situations. Long service life
The panel should last at least as long as the structure it heats. Minimum maintenance
The panel should operate at full efficiency for extended periods of time without needing servicing. Low-cost
The panel must provide the fastest payback when compared to all other heating methods, and must incur no expense after purchase and installation.
My attitude was that I would take as long as needed to get the job done – and that it would cost whatever it cost. There was the possibility that I might run out of resources without achieving recognizable success, but the possible benefits of success seemed to far outweigh the risk of failure…”
