Definitely a "must-see" for any train buff. Reasonable prices, good food, and trains!
Here is the report on the rest of our stay in Baker City, Oregon.
Wanderer in a strange land . . .
I got to hear some interesting stories. One lady's brother trained in Adair during WWII. She also remembered, at age 17, being whistled at by German POWs in a passing truck.
Yet Another Train Show. It was a Divisional Mini-meet for the Pacific Northwest Region of the National Model Railroading Association in Roseburg, Oregon. There were 35 – 40 people in attendance. When people “under 50” were asked to stand, there were only three of us. This is an old man’s hobby.
The kids had fun. Everyone seemed amazed I had it hooked to a Wii nunchuk. Younger kids would just run it back and forth. The older kids were given specific moves to make. A couple of kids came back for another turn.
One sharp young man started quizzing me about how the electronics worked. I ended up showing him the actual code. Not only could he read and under stand it, but he wanted to make some edits!
In getting ready, there have been some major setbacks. First, I accidentally applied 12V to the 5V bus and literally melted the microcontroller chips. Miraculously, that was the only damage to the Arduino's and I was able to easily switch the chips outs since they were in sockets. The motor shield, however, was not so lucky.
I ended up replacing both the L293 chips with some pin compatible SN754410s I had on hand, and the 74HC595N chip. I had to cut the chip legs with a dremel, desolder them, and then put in sockets so it wont be so hard if I do this again.
In doing some rewiring to avoid a re-occurrence of the chip cookout, I cause a meltdown of a different sort. I accidentally reversed the polarity of the 12V supply to turnout switching circuits. That supplied continuous current to the coils, resulting in failure in short order. I'm lucky I didn't start a fire. It wouldn't be the first sawmill to burn at Dawson Station (two mills burned down at the site before Ralph Hull built the current one).It is hard to idiot proof something when you are the idiot.
A late night of firmware upgrades the night before paid off. The layout performed (surprisingly) perfectly. Pressing the button started the mill sounds and had the train slowly move back and forth on the center spur for about two minutes. Lights, action, and sound must have made for a winning combination because it got first place in the diorama division.
This was a bit amazing because the returning champion, whose model graces this years plaque, brought another amazing entry. He must have been a bit shocked when they announce him for second place. He did win best in show, which I think he deserved. I did get one other surprise, the first ever Memorial Award for modeling spirit. The presenter mentioned that I've taken the layout to various events and have my daughters help me.
Luckily, I had a decent new picture ready for him to use (not the one on the right). He called mine out as one of his personal favorites of the year as well. Wow!
