Re: [CAD_CAM_EDM_DRO] Re: shielding for steppers

Hi Jan

Those lumps of ceramic with the little round window in the top (eproms) can
be quite entertaining - Plug one in the wrong way round and power it up from
a current limiting 5V supply and just watch the electrons whiz around <g>
If you get the current right (~500mA), it won't smoke, but it sure is pretty.

Regards, Paul.
