[sdiy] Small magnets

[Ian Fritz]

Hi all --

Tiny magnets are quite difficult to find.  Believe it or not, the best 
source seems to be Radio Shack.  They used to have them in the stores, but 
you can still get them online.  Be careful though, the dimensions can be 
different from that advertised.

The part # is 64-1895.  The web page says they are 1/8" diameter, but I 
measure more like 0.20"  (a bit over 3/16").

I haven't tried these with reed switches, but they sure seem strong.
