A Water or Fuel Level Sensor Circuit, by Mike in Alaska

We live up in the Arctic. Water is not always easily available in this area, various events can cause power to go out for weeks at time … what could possibly go wrong? The following design is for a fuel or water level sensor circuit. It uses a 66F002 MCU (Microprocessor Control Unit) with a built-in Analog to Digital flash storage read-only memory (A/D Flash EEPROM) using a sensor that has a prism built into a lens in the form of a sealed IR (Infrared) detector. When the sensor is bare (dry) the logic input to the MCU is logic …


3D-Printed Gun Components – Part 6 by M.B.

(Continued from Part 5. This concludes the article.) “All individuals are entitled to the utility to defend their humanity. Gun control has failed. You can’t stop the signal.” —from the original Deterrence Dispensed (now known as The Gatalog) website OPEN SOURCE FIREARMS “Open Source Firearms” is a term that I’ve used to describe those few firearms that are so popular that parts—as well as information about the firearms—are widely available. Moreover, these arms are so popular that even frames or receivers are being made by companies other than the one that first sold the firearms. An “open source” gun is …


3D-Printed Gun Components – Part 5 by M.B.

(Continued from Part 4.) I couldn’t find the command to flip the parts in the menus of Prusa Slicer, but a right-click on the object allowed me to “Mirror” it. It took a moment’s thought, to make sure I mirrored the hinge box and brace in the right dimension (X, Y, or Z). Once I figured it out and mirrored the two parts, I was able to print a right-folding brace! Have the Right Tools A small collection of tools will help you process a new print into a finished item. Power tools are seldom needed. Eye protection, and mask …

(Continued from Part 3.) “Am fear nach gheidh Na h-airm ‘nam na sith, Cha bhi iad aige ‘n am A chogaidli.” (Who keeps not his arms in times of peace, Will have no arms in times of war.) – Scottish Gaelic Proverb (with a hat tip to James Tarr)   Other Filaments Nylon Reportedly, nylon ranges from challenging to very difficult to print. It is temperature-sensitive and can warp as it cools. It requires temperatures at or close to 300° C., which many 3D printers cannot reach without modification. It also gives off fumes during printing. This and its temperature …

(Continued from Part 2.) Printable Frames and Receivers These projects generally use a 3D-printed frame or receiver, which is combined with firearm parts to create a finished firearm. Some of these designs can fire over 1,000 rounds without the frame or receiver failing. Projects in this category include a variety of AR-15 lower receivers, such as the UBAR2 and the Hoffman Tactical SL-15, a vast array of Glock frames, like the FMDA DD19.2,  Ruger 10-22 receivers,  and a variety of MAC11/9 lower receivers. There are also projects based on Smith & Wesson M&P pistols, Ruger pistols, Beretta pistols, CETME rifles, …

(Continued from Part 1.) “The price of freedom is everyone gets it, but some people will misuse it. …is that a reason to prohibit everyone from having it?” – Ian McCollum GETTING STARTED WITHOUT A PRINTER! If you’re not sure if 3D printing is for you, then you may be able to try it without owning a printer! Start by finding a fairly small and simple object you’d like to print in a database like Thingiverse. Download it, along with a free slicer program, like Cura, or Prusa Slicer. Now contact your local public library. Some libraries offer 3D printing—often …

WW3 Is Still On The Table: Europe Wants Boots On The Ground In Ukraine, by Brandon Smith

In the lead up to the 2024 presidential elections in the US the Biden Administration in collusion with UK, European and Ukrainian partners devised a plan to “Trump Proof” the war in Ukraine. In other words, they openly admitted that they wanted to prevent Trump from taking any actions that might force an end to the war and render a serious peace agreement. Part of that plan included the expanded use of long-range guided missiles supplied by western governments. These missiles require flight data from NATO assets along with NATO personnel to launch – Meaning, any strikes involving these weapons …


How Much Water? – Part 2, by R.E.

(Continued from Part 1. This concludes the article.) Back to First Principles What would be really useful would be a series of lights which would reflect how full the tank was, and if in addition to that, an audible alarm for high water-level. Perhaps I could build something like this using basic off-the-shelf electronic components and my rather rudimentary knowledge? Like most reading this, I am no engineer, and no electrician. My only personal asset seems to be that, I like to tinker with stuff. So, I dug out the multimeter and an old breadboard and began to experiment. To …


How Much Water? – Part 1, by R.E.

Over the past several years we have experienced significant disruptions to our normal routines of life. In the big cities, the heavy hand of government. The ‘two weeks to flatten the curve’ turned into years with numerous stay home orders, social distancing, lockdowns of churches, face mask ‘requirements’ and ‘vaccination’ mandates. Vaccine passports, at one point it was said were required for travel between provinces and crossing the Canada-US border. Police were pulling people over on the roadways to check whether or not your reason to be out and about was considered ‘essential’. It all culminated in million-person waves of …


Conspiracy Theorists Were Right About Everything, by Brandon Smith

For many years alternative economists and “conspiracy theorists” have argued that, according to the evidence, there has been an organized criminal cabal operating a long-running agenda to exploit and eventually destroy western culture. We have suggested that much of this agenda was being funded with our own tax dollar while using government institutions and NGOs as vehicles for social engineering. In the 20 years since I started work in the liberty movement (or patriot movement), I have seen corruption beyond imagining and it all culminated in 2020-2023 when many of us battled against the imposition of total medical tyranny and …


The Time to Plan is Now, by Prepping Engineer

The single biggest reason for failure is failure to plan. “When you fail to plan, you plan to fail” Another way to think of this is: planning is being prepared. That is prepping in a nutshell! This is stated in many publications and articles about many subjects. I have experienced this more times than I can remember in my life. What I have noticed the most is the repetition of this error by both people and groups. Sometimes this seems to persist and someone else “helping” them out of the repeat failure to plan. It is a mistake the first …


Bird Flu: What I’m Doing About It, by Sara Sue

The Current Situation The White House suggested, via the Press Secretary, that over 100 million chickens have died, or been destroyed, over bird flu.  I noticed that the price of eggs has gone up exponentially, so I polled my group of friends in an online homesteading forum, asking what they are seeing.  I also asked family members who live across the country.  The highest price I heard of from a family member in California was $10 per dozen for grocery store eggs.  Locally where I live, free-range chicken eggs are about $5-to-$6 per dozen. Eggs have been a standard for …


Fuels for Cooking, Warmth and Comfort – Part 4, by Lodge Pole

(Continued from Part 3. This concludes the article.) Cooking with Wood and Propane We do not regularly use our house wood stove for cooking. We can, but since we installed the wood stove, it has not been needed. Recently, I was given an old, homemade wood stove from an old-timer’s cabin. The stove is very well made. I have it outside of the shipping container and use it to cook on. It is an extremely large stove inside and out. It stays outside and will likely never be indoors again. Whoever built it, put several feet of ¾ inch steel …


Fuels for Cooking, Warmth and Comfort – Part 3, by Lodge Pole

(Continued from Part 2.) When the 2024/2025 woodstove season started, I had roughly seven cords of stacked, seasoned wood in the shipping container. We use about two cords of wood each winter. My goal is to always have at least two years of firewood on hand. To me, three years is an insurance policy. If I am unable to gather firewood one summer, I do not need to worry. I will simply gather more the following summer. I also store everything I need to gather, cut, carry, and split wood to prep it for storage. Our log splitter, chainsaws, axes, …
