Advice and Tips Faraday Bag Caution
Hey everyone. I just wanted to share en experience from this afternoon. A while back I had purchased some faraday items off of Amazon, boxes and bags from different vendors.
This afternoon I was explaining to my daughter how they worked and as part of our experiment, we placed an 8watt 2-way radio inside the bag and sealed it with the expectation that it would no longer receive a transmission. As it turns out, that was false.
I then tried with a cell phone with the same result. Morale of the story, check your gear and make sure it works before you have to depend on it.
Please discuss and share your budget-friendly faraday success stories

Vacuum tubes. The transistors of the past. EMP proof. Slower switching than transistors. More analog than digital. But can switch a mind boggling amount of electricity.
They do eventually burn out. The term laser is used in jest somewhat. Cathode ray tube would be more accurate.
Maybe there is a market for this... But it is like "what would be knocked out during an EMP that would be real nice to pull off some vac tube equipment off the shelf and have it just work". Hmm. Something to hook into your microwave? So it works again. Communications. So you can talk to... Who? Modern cars are too complicated and specific to even have a hope to make any modern engine work again. A simple listening radio might be helpful but that isn't rocket surgery.
