WHO KNOWS WHY THE NEGATIVE ION AFFECT BAD TO THE RUBBER, LIKE DESTROY THE  DRIVE BELTS FROM THE VCR.

Negative Ion generator : Nice idea , but how not to make an ozon generator too ?(Ozon is not really good to breath...)

intriguing article here: http://www.belljar.net/microbar.htm My device is in a sealed case with a "port" to allow the pressure to equaiize so in theory, I could fit a "mechanical reference" and filter, but that's done in the software. If I reduce the taps  I guess that I'll see very short local events but should also see global events like earthquakes ... I need to do more reading !!

bonjour  je suis votre réalisation depuis le debut question  peut on utiliser un module gps U blox NEO7N a la place de votre référence sans changement de soft arduino la configuration du module gps est elle automatique ou faut il la mettre en mémoire avant merci d,avance  cordialement  Ferreira Charles F1EVE

not sure what is actually "noise" and what is local micro variations ... perhaps another button to configure the filtering :-)
