DIY EMP / Solar Storm Electronics Protection 

As a “NEW” Ham (General). You have helped me immensely!! THANK YOU !! I ALWAYS stop & take time to listen to your videos. Keep up the GREAT Info flow. This video is Superb!!! Hoping to “chat” sometime Keep the Grind

Amazon also sells a metallic 5 gallon can and lid. I used your metallic tape to seal the seams and sponge sheets for cushioning. Finally, I wrapped my electronic stuff in good old AL foil. It passed the tests!

Your DIY budget faraday cage may not be perfect, but it is certainly better than no protection!

Try adding a ground strap military equipment is in metal boxes with a ground connector for a reason , the grounds are pounded in the ground on a angle so when you leave the area you attach to your truck and pull it out easily.

a steel tool box for your HTS, in a large steel file cabinet for your mobile rigs, can be used as large fatty cages,

Another way to test RF - stream content from your phone and close the lid and listen if the streaming stops after a few seconds. Try twice - cell service and WiFi.

Go down to your local Army surplus store and pick up some ammo cans. Remove the rubber gasket, remove some paint from the top where it meets the can, wrap with cord board, shove in some tin foil between the lid and can and there you go. Love your channel, thanks.

Add a solar power cell as an EMP will prevent standard recharging.

11:00 those bags are regular antistatic bags it seems. Nothing fancy.

i wonder if thicker steel walls would make a difference. im thinking ammo cans.. but also, i've read that good shielding / faraday cage has dual layers. so maybe a metal container inside another metal container.. insulation in between them. attaching a grounding wire to the outer shell of the outer container might be useful as well, and can be done pretty simply & low cost.. most houses are already wired for ground, or a grounding rod can be installed.. most HAMs are already utilizing a ground of some sort anyhow.

Suppose we had a Carrington level event and we had stashed our electronics in a Faraday cage and society was back in 1850. How would we know when it was safe to take our stashed stuff out? ... would amateur solar astronomy be a necessity after that event - looking for prominences and giant sunspots?

Can inside a can? Cage inside a cage. Insolate from each other. Wonder if that would fix the Weak RF getting in?

Hope is not a strategy, lol

I really need to do this too - I live in Hungary (we border Ukraine) and since things are getting a bit nuts here I better do it sooner rather than later. Firstly I's make sure to have a bigger distance or better insulator. Remember high voltages can cross big gaps so I'd have a much bigger distance between the can and the stuff inside (or different insulator) a bit of cardboard may not be enough to insulate against a 50kV/m EMP... For air It's typically around 3 kV per millimeter (kV/mm) I think so something better than that +20% maybe. I was thinking to use big old surplus ammo cans as I don't know how easy it is to get those trash cans here. I think I'll have at least two one sealed very well with stuff I will not open or only rarely - it will have an old laptop or Tablet + Battery + PSU + HD or USD drive loaded full of documents/manuals and eBooks etc., an offline copy of Wikipedia and other similar sources of info - with no internet this will be gold! Buck/Booster converter & maybe also throw in a solar power bank and/or Genesun charge controller and maybe a battery balance board + small mains inverter. I think basic solar cells and backup battery cells or car battery are safe outside if space is an issue. Plus of course some radios! In this can rather than so many commercial Faraday bags I'm going to use aluminium foil and put each item in a plastic anti-static bag and then wrap each item in the aluminium foil. For these items the inconvenience won't matter too much. For the second one I'd keep more items I want access to more regularly and the will need options closer to your solution to balance convenience and protection.

Great demonstration! KJ5BCP

When are you getting things out of the cage? Some time after an EMP a second EMP can come.

Would it improve the desired result by first lining the can with Faraday fabric? Then like you did and used the Faraday foam gasket to seal the lid. Just wondering because I have been trying myself to protect my a portion of my ham radio equipment.

Excellent video. KO4ESA/WRJR757
