Using a tablet as a Wi-Throttle with JMRI
Hello folks,
I was just wondering if any of you are running a Wi-Throttle/JMRI interface using a tablet over a smartphone. Can anyone that has used both comment on which they like better? I would think one of the smaller tablets out there would be better and less cumbersome, but I have yet to try it. There seem to be a multitude of 7" tablets out there that are retailing for under $100 lately.

FSM MacKenzie Milling Company - Need Instructions
I bought an FSM MacKenzie Milling Company kit. It has no instructions but the rest of the kit is complete. I was able to get the kit cheaper because the instructions are missing.
Does anyone you has already built the kit have a set of instructions for the MacKenzie Milling Company that they will sell me?
Or would someone be willing to copy the instructions for me if I can’t buy a set of the instructions?
Contact me offlist at jerrybn@gmail.com
Thanks.
The Hudson Bay Railway slowly comes to life
After years of "planning" or if you prefer procrastinating I have finally got the Hudson Bay Railway/Hudson Bay Mining and Smelting Railway underway. Benchwork started on January 1st with the "help" of a 7 and 4 year old. Benchwork has since been completed on the lower level and bus lines, roadbed and track have started to be laid out.
First a little background on the prototype:
Effective Grade
Designing a helix for a new layout. For the life of me I can not find a table that lists the effective slope induced by various radii. In other words, the smaller the radii of a helix, the more friction on the pulling force, thus a 2% slope at a 22" radius actually pulls like a 3.5% slope - or something. I remember using this table before. I believe it is from a J Armstrong book. Any help is welcomed Thanks
Locomotive Wheel maint
How do you clean locomotive wheels? I have a few the have been in storage for a long time.
Is the some type of alcohol or do you use fine sandpaper or Scotchbrite?
Also, some have/had rubber rings for traction. Where can I get replacements?
tia,
Down at the Station
Its been a while since I have been able to post anything. My schedule for the month of September was hectic and so nothing was done on the layout for a while.
Anyway I had to back up and redo some of the joints on my backdrop. I discovered that the tape did not stick to the smooth surface of the hardboard. I ended up removing three joints and sanding the hardboard surface. That little bit of roughness seemed to do the trick. I repainted the backdrop and clouds.
Louisville and Nashville Passenger Cars
I am a bit stumped. I cannot figure out what color the L&N's passenger fleet was in the late 1930's. Any of the color photos I've seen of them are from the 60's and they are all blue with yellow lettering and stripes. My best guess is that they painted them in a standard "Pullman Style" scheme of green with gold roman letters. Any help given is greatly appreciated. Ron S.
Nano Motor use?
I was browsing this morning and found a site called "SparkFun" with some interesting stuff. They are selling a rotary nanomotor for about $9 .... rotates up to 60 degrees. I was thinking semaphore movement or possibly even switch motor.

I am wondering if you can leave one stalled for a fairly long period of time.
LED locomotive headlights
I know this is a very simple question, but I'm totally addled when it comes to anything electronic-related
I want to convert my DC locomotive headlights from campfire-in-the-cab bulbs to LED's. Do I want to use 3mm bright-white LED's with 470 ohm resistors?
My plan is to paint the inside cab roof black, cut an LED into the plastic light inserts, and add a styrene "ceiling" under the light to prevent light leakage. Is that the "standard" method?
All advice is appreciated.
Jim
