Clearing out the attic

Hi All,

While clearing out the attic (after fetching the xmas decorations down) I came across a box of some of my 2 years olds toys which had been up their for a year and half.

I inadvertently squeezed one of the cuddlies and it sprung into life - lights and sounds.

I was just really impressed that stuff can be engineered to last for so long!

Or are my expectations pretty low.

Happy holidays everyone!

2 years? For electronics that's nothing, I am surprised the battery was still okay though, usually if they're stored that long they drain and tend to leak.

Especially older electronics devices which were made with larger junctions and more discrete components if the device isn't being used there is no limit to its shelf life.

Modern ultra high density computer components might have more issues with static aging as if I'm not mistaken the junctions tend to diffuse over time because the junctions are so small and close together.

As long as you use good quality alkaline batteries, they don't leak - but NEVER use old non-alkaline batteries, they leak terribly.

You have to assume he means the battery life. I mean obviously electronics components last longer than a year and half.
 
The battery in my old Weston (analog) multimeter was getting weak so I replaced it a short while ago. I wrote on it when I originally installed it: "6-29-82". It's a "Panasonic Long Life" battery. It still works in an LED flashlight but it's not very bright.
 
Might be a lithium mneary. They have a 10 year minium shelf life, and the switches on those analog meters basically left the battery completly floating when not in use. I think they have some alkaline technology that's reaching into the mainstream that will make alkalines last as long, redesigned interior structure and modified chemistry.

LOL. That would be roughly 36 years ago. I think electric toys back then would have had a poor shelf life.

Why ? Mostly it was motors and switches. About the only electronics I recall that failed where the selenium rectifiers in slot car power packs.
 
My memories of those toys are somewhat different. Maybe I was a bit rough with my toys. Or it was British workmanship of the 70's.

That should elicit debate from my fellow countrymen!

You could be right. I was a bit too old for toys at that point. Bought some for my nieces and nephews but did not track them. I purchased a 1 foot tall Gorilla like walking robot toy called Zog that had a long life. Maybe closer to 1980.
 
I watched a program the other night that categorised the 70's as the "That'll do decade" for manufacturing.
