With the caps the transducer experiences -~1.5V .. +~1.5V worth of deflection "down" and "up"; without the caps it experiences 0 .. ~3V worth all "up". So it's physically unable to deflect enough linearly I would think. | Would it be possible to add a 10 F capacitor on top of the 1 F one | and connect it (in parallel) using your magic silver thingy (that | I know nothing about), so as to avoid the soldering? It is electrically possible but all of this is in a metal can with very constrained height since the case and then battery sits on top of it. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkkwIlsACgkQOjLpvpq7dMrCVACeOrX8++KJayN08dN6Om92zMYb SZQAnAxC7S6ngZgZlmZI0p6VNcVwXzrL =FQfU -----END PGP SIGNATURE----- _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
