a little help with capacitive power supply values

[Dennis]

Hi all

OK 8 hours of flashing a 60W light bulb and no issues yet , Im feeling a little 'strobed-out' though :-), battling to decide to watch the light or the LED :-)

I'm also more keen on the OPTO , just wondering how it will survive the capacitive 5V floating circuit on the PIC side of things ... will explain more a little later.

Regarding the PIC for zero-crossing sensor , have you read the Microchip appnote 236a ? It should make you feel a little more confident , but I can try a diode if you like ?

Now about those screen caps and measurements :-) haul out that isolation transformer and scope and let's get some more info :-)
If you are curious and have the time of course ..

Kind regards

Nope, haven't read it. But I will in the morning.
But if it's OK with the folks at Microchip, then I guess it's OK with me.

I will read the appnote tomorrow... zero crossing detector is one of those things that will come in handy for me someday.

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
