Survivopedia – by CARMELA TYRELL
Even though we’ve all seen the effects of solar flares and their ability to knock out electricity and communications, some do not believe that an EMP attack will lead to social collapse. But it will…
As someone that loves to tinker with electronic devices, I am a firm believer in the potential for both natural (odds have increased substantially in the last few months because Earth’s magnetic field is weakening faster than expected) and human-made EMP attacks.
That being said, I also know that many of the worst problems that will come from an EMP attack can be reduced by using older technologies that rely on electronic components which are far less vulnerable to an EMP.
Electronic Devices Are Not As Complex As You Might Think
If you find yourself confused by electronic devices, simply remember that every component does one of five things with mathematical precision depending on the materials used:
- allows electrons to flow through it
- does not allow electrons to flow through it
- prevents electrons from flowing until enough of them build up on one end of the component
- allows electrons to flow if they are moving in one direction, but not if they try to go the opposite way
- atoms within the component may change the organization of their own electrons so that the flow of electricity is accelerated, slowed down, or number of passing electrons increases
Once you understand what each component does, connecting parts in various patterns will create larger devices that meet specific goals.
All you need are the right components and a diagram that shows you how to arrange them.
Electronics Before Integrated Circuit (IC) Electronics
While Tesla and Edison were battling for control of how electricity would be produced and transmitted, most people were relying on oil lamps for light and cranks to start their automobile engines.
Interestingly enough, everything from the first telephones, victrolas, and radios, to televisions and nuclear bombs operated without the use of microchips and other semiconductor components that are highly vulnerable to EMP attack.
Therefore, if we go back to “old fashioned” electronics, we can both store and maintain EMP resistant devices. Perhaps even better, when you go back to basic electronics, you can fashion components from the same kinds of Earth or nature/wilderness based materials that you might use for a fishing pole or some other survival need.
To Build Or Not Build Semiconductors?
As you may be aware, a semiconductor is a special material that is selective in how to allow or denies passage of electrons.
When semiconductors are arranged in layers with insulators (materials that do not allow the flow of electrons) and conductors (materials that easily allow transmission of electrons), you can create all kinds of fascinating effects that take the place of older style electronic components.
This includes resistors, capacitors, relays, diodes, crystals, vacuum tubes, transistors and circuits (paths that arrange electronic components).
Many people today mistakenly believe that it is not possible to avoid using semiconductors in electronic devices. Further, there is also a belief that semiconductors will not be available because the technology will be lost to build integrated circuits.
That being said, you can still create some semiconductor based applications by layering glass and copper. You can also use crystals, capacitors, and resistors to duplicate transistor effects. While they may take more power and require more maintenance, they will still be of use until other technologies can be recovered.
Simple Devices That You Can Build And Keep On Hand
Here are just a few simple things you can use to make fairly powerful electronic components. Once you master making these basic elements, you can easily go on to building radios, transmitters, perimeter defense alerts, generators, and jury rigging for bypassing electronic systems in other gadgets.
- salt water, oil, and paper based capacitors
- wood and paper based resistors
- speaker wire and metal rings for coils
- simple grounds from wire and nails
- earth batteries
- solar power arrays that use heat to generate electricity
- Tesla turbines and shell designs that run on moving water or air
- quartz crystals for translation of sound to electrical pulses
Suggestions for Further Study
Not so long ago, you could visit your local Radio Shack store and pick up an electronics project kit that would easily teach you about electronic components and how to arrange them into useful circuits.
Unfortunately, if you walk into a Radio Shack these days, all you see are endless arrays of cell phones and pre-built devices while “old fashioned” electronic components are relegated to dusty bins in the darkest corner of the store.
To add insult to injury, project kits for kids these days are little more than solar cells, snap together robots, and an IC chip that do very little in the way of hands on educational building and exploration.
From that perspective, I recommend starting off with a used book on introductory electronics. Make sure the table of contents includes information on basic principles of electron movement, resistors, capacitors, diodes, transistors, relays, crystals, and coils. There are also some good YouTube videos available if you would prefer that form of learning. I also highly recommend the Mechanical Universe series if you are math inclined and want to delve into physics more than electronics.
If you do some research online, you will also find a few places that offer surplus electronic components. You can get grab bags of different components to practice with, and then gradually move towards making your own parts. For example, once you build a simple FM radio from basic parts, you can go on to make your own capacitors, etc as the next stage in your learning. With regard to tools I recommend the following:
- a multi-meter that measures AC/DC, amperage, resistance, and capacitance. It does not need to be digital or hook up to a computer
- a good quality soldering iron with variable heat settings
- circuit board etching kit
- breadboards and wire connectors for practicing
- grounding strap and non-magnetic tools
- calming aides for your family members if they fear you will blow up the house or get into some other silly mischief
- a place to work outside the house if calming aides do not work.
“Old fashioned” resistors, capacitors, relays, diodes, crystals, and simple wire can be used to build radios, transmitters, generators, and many other simple devices. While you may not be able to repair a cell phone or computer, these old technologies offer a starting point that can be used for survival, and ultimately, recapturing lost solid state and other technologies.
Perhaps even better, if you know how to create these simple electronic parts, you can also make them on your own from bits of paper, ore bearing rocks, natural crystals, and other items that you don’t normally think about in terms of building electronic devices.

Every component does only five things with mathematical precision….let’s see if I remember my basic electronics class from 30 years ago.
1. Allow electrons to flow through it…..a resistor. (most common)
2. Does not allow electrons to flow through it….an open switch.
3. Prevents electrons from flowing until they are built up at one end of the component…….a capacitor.
4. Allows electrons to flow one way but not the other way……a diode.
5. Electrons are slowed down or accelerated…… a step up or step down transformer. (not to sure on that one) How’de I do? Glad the test is over…let’s have a beer.
Way ahead on the beer but for the most part you get it.
1 Any conductor will allow electrons to flow.
2 An insulator will stop electrons.
3 Right on with the capacitor(all be it not the only things)
4 Diodes (right again)
5 A resistor can be used to step down voltage(charge) OR limit current(speed) but a transformer works to for both.
That dusty box relegated to the corner IS my shop.
Anyone need any parts? lol
EMP or not I will be listening to music. On a nice Marantz or McIntosh amp most likely.
The Navy had what is called NEETS modules. It was a training course. It can be found here( http://electriciantraining.tpub.com/ )
Very good but not easy. Everything from what is matter to microwave principles. enjoy!
