Yes, ground yourself through a 1M or 100K. Bad idea otherwise. :) Didn' t mean to confuse anyone... I can't understand an application where the user directly touches the pins... that seems like an unreliable input source... but hey, who knows? Thanks for the clarification. How about a ckt. that measures capacitance at inputs, rather than a direct connection to the pins? Or make the user's skin a (very low current) contact b/w two points? ---------- > From: Mike Ghormley > To: PICLIST@MITVMA.MIT.EDU > Subject: Re: esd protection > Date: Tuesday, December 16, 1997 2:54 PM > > Justin Crooks wrote: > > >Well, how about grounding the person touching the pins? > > Your basic idea is correct, but needs a little clarification to keep > newbies from taking your literally. > > It is *never* a good idea to directly ground yourself when handling > electronics, yes?
