FYI,I took apart my $3 "shaker" LED light,and the "magnet" was just a
piece of unmagnetized plain steel rod,the coil wires were tucked under
the lower battery terminal,*not soldered to anything*,and the
batteries were a CR2032 and a thinner CR2025,for a total of 6
volts.They evidently use the (CR2025?)cell's internal resistance to
limit LED current.


Addendum;interestingly,they used the same circuit board for the fake,and
the holes and copper traces are all there for 4 diodes(a bridge),a
resistor,and the capacitor.With the addition of those parts and a strong
magnet,the shaker-generator would be functional.I may shop around at
Skycraft Surplus and see what those parts would cost,just for grins.
