Making an X-10 lamp module immune to dimming
Anyone know of a mod to make an X-10 lamp module immune to dimming? If not,
does anyone have any suggestions on how to accomplish it? I have lots of
extra modules to experiment on, and it would seem that there's a control
line that tells the triac how much to "chop" that could be modded to always
run full tilt. That way, a brighten or dim command wouldn't affect them.
I found the schematic at Dr. C's site:

He also did some work attempting to make the switch smarter

by dropping in his own PIC, but was overtaken by events and commercial units
becoming available that did what he wanted.
It looks like the triac, BTA10-400C, gets controlled by pins 6 and 8 of the
78561 microcontroller. The trick is to make it deaf to only bright and dim,
not on and off.
