Most controllers these days have low impedance (resistance) outputs so that the voltage doesn't change much when the load varies
,
Isn't physics clever!!

Wot 'e said ^ !
[ aka common collector or emitter follower regulator ]

which got me thinking over my gin&tonic !
that the output impedance is much reduced compared to the source impedance ( the output of the wallwart / input to the controller )
So, for the consideration of the hive mind, aka the NGF collective, : would a suitable point for introduction of an extra resistor be at the input of the controller (thus reducing the input voltage) ie. between the wallwart output and the controller input ? Its disturbance to the output impedance being reduced in proportion to the transfer function of the emitter follower and its Hfe ?

Bearing in mind the aforementioned G&T, dont try this at home without an adult assisting

but have they brought the vaccine with them ?

Sorry Andy, normal service may be resumed soon

Can we please have a workable definition for 'normal' please...  Some sort of benchmark is necessary for a discussion of this nature.....

O.M.G you're (we're) all mad!!. Aren't we?? Aren't I?? Now where did I leave those pills - Oh yes - next to that bottle of Scotch.
See you all (even if there's only one of you) soon...
Night Night all...
