Reply to "Proposed Solution to DCS Watchdog in Yard Tracks (DCS-RC WD Gerber Files Added to First Post)"

John, interesting comment on the 0603 smd size. With my limited (but growing) smd experience, thats pretty much the smallest size that seems practical. I accidentally ordered a few 0402 resistors a while back, and promptly tossed them out when they arrived.

I was happy to see that all parts for your smart motherboard project are at least 0603, and it went together quite nicely. I finally figured out an smd soldering technique that seems to get the job done with minimal muss and fuss. The only pesky part on that board is the tiny little indicator led, and being polarity sensitive, you need to get it right!

Anyway finally after all your prodding I took the smd plunge, and here we are. It seems to be working! Nice when an old dog can still pick up a new trick or two.
