Hi all,

Chris Chapman suggested a iron/steel "L" bracket to the sides of the upright
magnets to enhance
the internal coil field gauss.  I tried a rough equivalent iron block, and
see about a 100% peak
voltage increase (from the previous ~5v to ~10v) with the coil
displacement!  Thanks Chris!

I added a new picture and text to the bottom of the same web page:

Take care, Meredith Lamb
