This is Mike and today I was consolidating my scrap electronics drawer and found this:
A broken calculator.
I decided to take the screen and the solar cell out.
I removed the back panel
and noticed the lack of wires to the cell.
I checked for broken solder connections
and found none.
The solar cell is fake!
I just wanted to show you this ridiculous example
of how cheap electronics can get.
Christianne picked up a nearly identical one for me,
so I could check its solar cell too.
I disassembled the new one
and discovered that the cell is real!
I guess that some companies feel that it's more profitable
to substitute a real cell for a piece of glass.
Thank you for watching.
