RE: Interesting Concept... or complete idiocy?

["Ian Lowe" <ian@xxxxxxx>]

yeah, I have the PDF of Mr Plunkett's home brew X-10.

And, yeah, his parts list is highly extensive... tbh though, he has tried
to
replicate an X-10 module in it's entirety. He still uses a 120khz tuned
circuit, with amplification stages to boost that signal till it pops the
rails.

What I am suggesting is effectively removing the zero crossing detection,
oscillator, amplifier and doing it all on the digital side. by being smart
with the ADC signal..

I guess what Li posted is the closest to what I am suggesting, although
again, this is as an enhancement to an existing circuit rather than as a
fundamentally different approach.

I think i'll try some experiments, and see if I can get something useful to
happen.

Thanks!

Ian.

No, I only found it this afternoon, looking quickly at the component list I
don't see anything particularly exotic so I would guess about 20-30 quid.

I was only looking to see how he was driving the triac as my own attempts a
couple of years ago to make a disco lighting controller where not that
successful and i've still got a maplin bag full of triacs & opto
isolators.
If i'm really sensible I'll give this one a miss.

Alan,

Have you looked into building one of these??  Any ideas of approx cost?

Cheers
