I suppose we’ll always need them although a good engineer is worth half a dozen techno-nerds. Yet the point of this is to try to raise your awareness of just how fragile the whole electronic, high-tech thingy is.
Anyone out there familiar with batteries?
They come in all flavors, sizes, capacity, and “life”.
To put it in context.
There you are, miles from anywhere, at night, confident that the GPS in your hand will guide you safely through many miles of danger and this pops up on the display:-
Oops! What exactly was your back up plan?
Only it doesn’t stop there.
GPS works off satellites doesn’t it? What if the government haven’t paid their bill, switch them off to prevent the bad guys using them, or one of those solar flares or even an EMP pops them all?
There again you could have just dropped it, got it wet, or as per all electronics seem to do, the warranty runs out and 2 days later it dies.
Now I can do this all day with electronics.
Radio’s, laptops, dongles in laptops, electric shavers and toothbrushes. Cars, trucks, and most anything with electronics in it or powered by batteries MAY fail (and usually does) just when you need it the most. Usually at the drop of a hat aka without warning.
So it sort of messes with my mind how and why so many rely on electronics as opposed to good old-fashioned skills.
I was reading an article about electronic surveillance.
Who wrote it isn’t important but what was notable was the reference to using scanners, radio’s, laptops plus dongles and applications for communications, navigation and surveillance purposes.
So, I offer the same scenario with a few appropriate add ons to ponder about. You name it and electronics can fail because of them.
Magnetic Compass, paper map (very retro), ranger beads if you like and can’t count paces, and an accurate time piece is essential.
- Weather forecasting.
Your eyes, ears, clouds, animal and insect behavior, and reaction of vegetation.
Binoculars, ears, eyes, smell, and a dog.
- Torches / lights.
You can get wind up and dynamo types.
Here I like solid state LED “bulbs”. Only because they consume so little power. There again, do you need to travel or work at night showing lights?
OK, I’ll give you this one YET does everything have to be so high-tech? Look inside most modern equipment and all you’ll see is integrated circuits (IC) and microprocessors (uP). Perhaps at the RF power end some transistors or FET’s. Now something fails in the field. Even if you can source a replacement IC could you replace it? Especially a surface mounted device (SMT)?
Only did I mention batteries in the article
I mean at all?
