Large Scale Central

Signals on the NVRY

With the exception of a support failure on the maintainer call plate, they come out really nicely off the resin printer

Nice!!

I didn’t know you were using the resin printer again, did you install a vent system?

Yea, I rejiggered the vent that I have, and had a big box fan in the window blowing out. With a small space heater going I still kept the room around 70f, since it wasn’t bringing much cold air in. We’ll see how effective that is, plus the PPE I wear.

I haven’t really enjoyed wearing PPE since Janena left.

Quick coat of paint.

Bob this is kind of a stupid question but why nut use a raspberry for control?

I will probably use a Pi for the central CPU once I get everything working. They’re neat, capable machines. I have a few running things around the house.

Nope. Still highly allergic. I’m bummed.

Anyone want to buy a Saturn 3 Ultra and the wash and cure stations?

Really sad to hear that Bob, it sounded like things were working out.

I just realized that’s a 12k resolution printer.

Dang puts my 2k printer in the I can’t believe I’m still using it until I run out of support category.

I’d put up an offer, but I just blew my hobby budget for a while after acquiring some more rolling stock.

Got my flyer in the mail last week for their big open house Saturday, March 14
9am-3pm and I thought of you.
You can operate the levers on the interlocking machine and watch the illuminated model board and follow a simulated train. You can also ask questions like “How many cigarettes were smoked in here from 1930 till 1992” ? They cannot answer that one only response was A LOT!

Behold the elusive tri-color (Red/Yellow/Green) LED. These have been hard to find not in a surface mount configuration, but I found a supplier. This will allow me to make single-lens dwarf signals, which will be less prone to breakage.

Does it tick them off if you intentionally set up a head-on meet ?

Nice. Somewhere, in a box around here I have a film canister full of 5MM RGB LEDs. I went with the more rare common Anode to work with systems that switch the ground side.

I just realized yours are R Y G, not RGB. No wonder they are hard to find!

Yea, exactly. RGB are everywhere because they’re used as individual pixels to make huge LED displays.

For more fun you should wire them in series. That way if you lose one you lose’em all !

The CTC boards showed up today. Looking at them, you’d almost think I know WTF I’m doing. You’d also be wrong.

But anyway, first order of business is to install the processor board and the two IO expanders, and make sure that I didnt screw up the board layout.

And I didnt screw it up. Next is to install the DIP switches for address selection. That’ll be after dinner.

That motto has worked for me on a professional level for many years! I just didn’t know how to word it professionally.

That was great!!

Address selection seems to work.

Please forgive my ignorance about these things- when you install the processor board, DIP switches, etc., do you have to solder them in or are they kind of a press fit? This is all very impressive to me, to design and implement such a complex system. Thanks for showing what goes into it.
