for the wigwag on a mobility scooter, [Shoprider ERSF, Circa 2014?] where i'm modding controls, and unavoidably reducing wigwag swing range. i wish to increase the rate of change on the 5K pot/voltage divider by between 1.5 and 3 times [selectable?], largely independent of supply voltage, which varies from v to v/10. v/ something less is acceptable.
quiescent state amplifier Vin=Vout=V/2 ==wigwag pot centralised, or unit disabled.
an unknown is the rest of the cctry response to an increase in total current by voltage divider [doubled? as output reistor prob needs to be 2.5K]
a 50K pot is in series wth the wigwag to lower max possible speed range as needed.
i thought FET because it's a voltage sensing system, and i can't reconcile that with bjt', as i've forgotten too much.
if a cheap kit/module exists [in Oz?] pls recommend. .
thx
