Mobile Device Battery Management – Part 4, by J.M.

(continued from Part 3. This concludes the article.) Battery Safety If you’ve ever watched the news you’ve probably heard stories about exploding Lithium batteries in cell phones, electronic cigarettes, USB battery packs, etc. They’re all true – lithium is an extremely hazardous chemical; it’s poisonous, it’s unstable, it burns extremely fast and hot (>3500F) and it produces hazardous gas when it burns. So why is it used in all of the most common forms of battery electrolytes? Because it has the best cost/size to energy density ratio currently available and manufacturers decided it’s worth the risks, and consumers agree with …

(Continued from Part 2.) Battery Drain While I briefly mentioned battery drain earlier it’s worth going into a bit more detail. Drain rate describes how fast a device uses power when a device is in operation. Examples of high-drain devices include things like digital cameras, GPS devices, portable gaming consoles, high-lumen LED flashlights, radios (when transmitting) and motorized devices like power tools. Some low-drain devices include television remote controls, wall clocks, smoke detectors, and red dot sights. Rapidly draining a battery’s charge can significantly shorten its life, so choosing the right type of battery for each type of device is …


Mobile Device Battery Management – Part 2, by J.M.

(Continued from Part 1.) Rechargables Rechargeable batteries come in a much wider variety of chemistries than primary ones, including nickel–cadmium (NiCd), nickel–metal hydride (NiMH) and various lithium-ion (Li-ion) and Lithium Polymer (LiPo) chemistries. It’s important to understand the ‘Li-ion’ and ‘LiPo’ aren’t specific chemistries, they’re categories of chemistries that use Lithium as one of the components of the electrolyte. Li-ion batteries use a liquid electrolyte, are usually cylindrical, and common chemistries include: Lithium Cobalt Oxide (LiCoO2, LCO): Known for high energy density and used in portable electronics like smartphones, tablets, and laptops. It has a nominal voltage of 3.60V with …


Mobile Device Battery Management – Part 1, by J.M.

There have been many articles by myself and others on SurvivalBlog that discuss the use of mobile electronic devices such as radios, flashlights, cell phones, red dot sights, drones, cameras, etc. for emergency preparedness and disaster scenarios. The one thing all such devices have in common is that they require power of some sort, usually in the form of a battery, and without power those devices are about as useful as a paper weight (I guess you could use them as projectiles). Understanding how batteries work and how to best manage them can help ensure you get a long and …


Raising, Hunting, and Harvesting Animals – Part 6, by Lodge Pole

(Continued from Part 5. This concludes the article.) The .223 Remington I love the .223 Remington (.223 Rem). The rounds are relatively inexpensive and can be found anywhere. There is a plethora of bullet grain weights, designs and bullet tips. There is also an unlimited amount of firearm platforms to find that best fits you and your needs. I use a bolt action Ruger American Ranch rifle. Ruger makes an excellent, inexpensive and durable rifle chambered in 5.56 NATO. It has a detachable magazine and the comes in a 1:8 twist. My rifle has consistently and accurately shot a variety …


Raising, Hunting, and Harvesting Animals – Part 5, by Lodge Pole

(Continued from Part 4.) Practical Hunting Gear The basic gear I carry, regardless of season, is listed below. Clothing that fits and is proper for the environment you’re in. This includes a hat. Always have a change of socks. Firearm and spare ammunition. Every single rifle and shotgun I own has an elastic buttstock ammo carrier as well as a sling with ammunition loops sewn in. (Butler Creek makes a great sling with ammo loops.) I like these because accessing spare rounds is more convenient and it doesn’t require me to carry so much ammo in my pack. Knife. I …


Raising, Hunting, and Harvesting Animals – Part 4, by Lodge Pole

(Continued from Part 3.) Pros and Cons of Raising Animals for Food As with anything in life, there are pros and cons. Below, I have compiled a list of my personal pros and cons when it comes to raising animals for food. Pros You can control what variety/species of animals you want to raise to give you the most amount of meat. You can choose the type of meat you want to have in your household. If you like peacock meat, you can raise it. If you like ostrich eggs, you can raise it. With chickens, you can control the …


Raising, Hunting, and Harvesting Animals – Part 3, by Lodge Pole

(Continued from Part 2.) Water for the Flock For the first several years of raising fowl, I had a 20-gallon rubber water tote in the chicken coop. Every couple of days, I would have to dump all the water out and refill it because the chickens would sit on the edges of the tote and defecate into the water. In the heat of summer, the water would turn green within a day or two, spoiling all the fresh water. I was wasting more water and time than necessary. I began designing a gravity fed water system with a livestock auto-feeder …


Raising, Hunting, and Harvesting Animals – Part 2, by Lodge Pole

(Continued from Part 1.) The following are the basic tools I use to harvest and butcher fowl: Large stainless steel bowl. I put several quarts of water in the pot (the amount of water varies on how many birds I am harvesting) to keep the meat from drying out and to help keep flies away if they are present. I also butcher where running water is easily accessible to wash my hands when necessary. Sharp knife. My preferred knife for cleaning and butchering is a medium-sized, antique, high-carbon steel butcher knife with a very thin blade. This knife is from …


Raising, Hunting, and Harvesting Animals – Part 1, by Lodge Pole

In late 1929, when the stock market crashed and the Great Depression began, the population of the United States was around 121.7 million people. All through the Great Depression, it was unheard of to leave roadkill on the side of the road left to rot. With high unemployment,  the hunting pressure was heavy. Small game, like rabbits and squirrels, nearly went extinct in large parts of the United States from being over-hunted, to feed desperate families. Today, in 2026, the estimated population of the US is 348.3 million. If animals were being hunted to near extinction when the population was …


The AR Super Safety – Part 2, by St. Leibowitz

(Continued from Part 1. This concludes the article.) In Part 1, I presented an overview of the Super Safety and why it was chosen. Now, I will move on to describing some details on installation and function checking. This will cover the modifications to install a Super Safety on only a standard 5.56mm AR-15. The MP5 and AR9 models of the Super Safety are very popular but do require extra parts as well as some other considerations. A successful 5.56 install will help you get used to what you’re dealing with, since it is by far the most straightforward. Parts …


The AR Super Safety – Part 1, by St. Leibowitz

The following is an overview on the installation of a new gun part known as the Hoffman Tactical Super Safety. It is a do-it-yourself open-source forced reset mechanism characterized as an “active reset trigger system.” It makes your AR go fast. If you do not approve of guns going fast, then please don’t read this article. You can desist from clutching your pearls and return with alacrity to the closest available nursing home, the banned books section of Barnes and Noble, or the United Methodist Church. Your cat misses you. Everything discussed in this article is currently legal at the …


Some Extreme Cold Weather Advice, by Hollyberry

We have all seen the media drama these past few weeks regarding the weather. Until about 10 years ago, I never even heard the term “polar vortex”, it was just winter. Living in Maine for the past 20 + years and making through the harsh winters has been a humbling and rewarding experience. Every spring you can hear people sigh in relief. I feel sorry for the lower portion of the country that has been experiencing the extreme cold, ice and snow. It’s something that takes getting used to and it helps to have the proper clothing and gear to …


Antenna Building: Theory and Practice – Part 3, by Hoofer

(Continued from Part 2.  This concludes the article.) In Part 1 and Part 2, we hit a few of the “How it works” or “Why it works” stuff.  Proven by experience, or our family ham antenna business would have failed immediately.  So, what do you have laying around the house, farm, garage – that can be turned into a high performance antenna for just listening? In the basement / garage, Metallic stuff, old copper pipe that burst from freezing, Telephone wire, cable TV wire, Ethernet cable (4,6,8 strand stuff), Iron pipe… will work, again not as good. Old extension cords! …


Antenna Building: Theory and Practice – Part 2, by Hoofer

(Continued from  Part 1.) A typical Trucker’s dual-mount CB antenna has 2 coaxes down to one connection to the radio.  We want the signal from both antennas, unified exactly for a nice strong signal / in phase voltage pulse, into the radio. Because the antennas are on the sides, like mirror mounts, the strongest, best signal (in phase), will come from the front and rear of the truck, while signals from either side, will cancel each other out (a little bit). The same thing happens with our Vertical antennas, 2-3-4-5-6-7-8 of them.  We want to get rid of the noise …
