Hi,

I've been reading up on interference caused by LEDs on the
power bus in the archives, a problem that I'm having in my
homemade and commercial cases. I've minimised the problem
by strategically placing the offending modules, but there was
some discussion about including large capacitors between the
power rails to help stop this problem occuring in the first place.

Has anyone done this, and was it successful

What constitutes a "large capacitor" and what type. Does the
polarity make a difference

Yours Aye
