My health has continued to deteriorate and things have reached the point that almost any movement of my arms and/or upper body aggravate my spinal cord, resulting in severe cramps, spasms, pain, etc. Consequently, I will not be renewing my website hosting agreement for davehouston.org/davehouston.net when it expires on 10/21/15. If there are any files there you would like to copy, you need to do so before that date when they will disappear into the ether.
As noted in another thread, I have a CM15A with datecode 13F24 that is a redesign with far more extensive use of SMD components than the only known (to me, at least) earlier through-hole version. I will try to post pictures of the PCB in the next day or so, if my spinal cord allows.
I have no idea whether current shipments utilize this newer SMD design or the older through-hole design. In any event, it's a shame that the SMD version did not replace the Cypress MCU with the Atmel ATmega328P (+USB/Serial chip). It would cost less and allow Arduino acolytes to create programs and apps for it, guaranteeing survival of the X10 brand.
