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

Biting the bullet, waiting on my digikey, mouser, and oshpark orders to come in. I figure I'll try and solder the board first, if I don't screw that up then soldering a 3 pin header on an unreplaceable board should be a walk in the park. Happy to see all this was worked out by you guys way before I even considered dead power yards.

I hear that MTH is getting more DCS Remote Commanders produced, that's good news for the folks that want the watchdog generator on their layout.  Mine are happily generating watchdog signals on all my tracks.

Well that's good news to hear at least, although you'd think it would be cheaper to just... Add a constant TIU watchdog signal output via a software upgrade (TIU v7 anyone?). But who knows, maybe they are doing another batch to help with control system sales.

@gunrunnerjohn Can you add a BOM to the first post? I found another thread with a BOM list... but now that I have it all in front of me it looks like I may be missing something.

Here's the thread I found the BOM originally: https://ogrforum.ogaugerr.com/topic/pbw-needed?reply=100540307597091066#100540307597091066

However it appears this WD gen rev uses a different PCB layout/parts from the post above

Edit: I'm just now realizing that the BOM on that thread is for an older 555 revision of the board. I see a Rev 2 on the bottom of this board so that explains the wildly different PCB layouts

Here's the BOM for your version, that was the first generation of the design.  The 555 version was the later version, it required no calibration.

I have a few kits left for the 555 version of the PBW. Send me an email if interested, email is in my profile.

It sure would be nice of MTH did resume production of the remote commanders.

Ahhh gotcha, well good thing these pcb's were extremely cheap lol
