Hi all

Steve ...
Also check out the posts by Dave Houston regarding the x10 info ... they have indeed been using an MCU's for many years and I recall seeing a post or two by Dave referencing certain models in particular even a PIC 12XXXX if I'm not mistaken.

You could also always conduct AC testing on low-voltage 'downlights' (not sure what you call them in the US or Europe ... ?

Keep those posts coming , this is a very interesting thread so far :-)
Oh and see post 66 (clickety clicks :-) )
Oh .. and last but not least a popquiz question... Am I using a COMMON LIVE design or a COMMON NEUTRAL design ...and why ?
Kind regards
Dennis
