http://www.rimstar.org/materials/piezo/how_to_make_rochelle_salt_piezoelectric_crystal.htm Some folks may wish to experiment around and try to make their own Hi Z microphone from home grown crystals. The process is basically Home EC 101. All you need is baking soda, cream of tartar, distilled water, your oven, pyrex cookware, and the XYL's permission. The expense is not great, so, why not? |
