Costly? A 300W dimmer module costs like nine bucks. When I add up the
price of the components required to duplicate that, I have trouble
figuring out where they're making a profit.
They're all PIC-based, by the way...the modern dimmer modules contain
12c508 chips.
It would be an interesting job, actually, though the
MCU would be largely
wasted. It's smaller than an equivalent set of CMOS logic, though.
Well, the 12c508 is a *tiny* processor with a *tiny* control
store...

Does anybody have any X-10 software for the Apple II?
I do have the X-10 software for the C64. We got permission from the company
to post it to comp.binaries.cbm -- the company owners were tickled people
were still using C64s to control the modules, and said go ahead as long as
it isn't sold.

As for your only over the AC line wall switch, I've had them like that and
rebuilt them and they actually last longer than the original once the
tension is put back. I've only had one to actually be broken inside so I
took it back to RS and they gave me a new one (I know the manager so it was
easy). Wanna huess what they do with the old broken one - that's right -
circular file (it's a write-off).

I've gotten tons of stuff like that from my last two employers - offered to
test and/or repair for some overtime but they just wanted to get rid of the
stuff. I presently have a Dell 17" monitor I use in the shop that was thrown
out by day shift and I reclaimed - needed a tweek on the brightness pot and
it's been fine for the last year. Like wise I got 2 4.3gb Microplis SCSI
drives that were "defective" but only needed someone that knew how they are
supposed to be terminated to make them work right. They're my main drives
for my RAID array in my Dell 486 server (with Kingston Turbochip 133).

That sounds familiar....I probably did see you.
I'm about 6'1", was wearing some sort of hat...probably my Novell
hat, and was wearing an embroidered "Heil Sound" shirt (I was a
semi-official employee for the weekend...)
And yes, Friday was a joy for those of us wandering the flea
market. I made it through the early sprinkles, bought 5 Storage
Dimensions raid cabinets, and grabbed my umbrella when I toted
'em back to my car.
I gave up, however, when the really black clouds and lightning
moved in.... decided it was no longer fun.

Some are PIC based, the newer ones are, some of the modules are not.
I am not suprised. I think they used to be based on
some kind of ASIC,
but it would make sense for them to use PICs now.
The 'Old School Hacking' community is using PIC, AVR, and Zilog controllers
to interface between the AC and the PC. We've come up with some interesting
hacks. See Dave Houston's (http://www.laser.com/dhouston/bx24-aht.htm) pages
for a really good example.

they can probably make a buck.
They require a central controller, though,
don't they? What do those cost?

It probably has more than enough control store,
as it just has to count up and
down for each pair of interruptions of a pair of beams of light. The
12C-whatevers don't have much I/O, though. The arrangement I had in mind
wouldn't require the aid of a central controller and the communication with it,
but would require it be able to "see" a pair of photosensors, e.g.
phototransistors, and pulse an LED at a fairly high rate, in order to determine
which way the interruption was traveling, thereby making it possible to
determine when there were no more people downstream of the control, indicating,
therefore, that nobody would benefit from the turned-on light. Including a
small transformer and regulator, the best I could do probably wouldn't cost
under $9, though, but it would fit in the box with the light switch and wouldn't
need a master controller.

You don't need to do EVERY switch in the house to "get into" it. You just
need ONE switch that is inconvenient enough to rationalize the "need".
23 years ago, the cost to "get into" X10 was about $30 - $40 from Radio
Shack, or Sears. That was $15 - $25 for a controller, and about $15 per
module, which included wall switches and duplex outlets, neither one of
which "had to have an outlet into which to plug".
BTW, the wall switch modules in those days resembled a normal toggle wall
switch, except that when you turned the light on locally (by flipping the
switch, it delayed a second before turning on. Some people couldn't
handle that. Also, when the local switch was in the down position, the
light could not be controlled remotely. The newer switches are push
button, with a slide switch for lock-out.
Now the modules are about $15, but they have become commonplace enough
that there are occasional special deals, such as $2 or $3 modules.
