  1. Bluetooth Locomotive Transceiver? Flywheel Sensor


    The IR sensor input had to be moved to the flat end of the flywheel to get a good signal for the brain. Apparently the curved surface was not providing enough reflected IR. The flywheel currently has a thin piece of poster board that is a good IR reflector. This paper needs to be replaced with some IR reflective paint for better balance of the flywheel.

    With this new setup the ...

  5. Where is Mr Train contest is on again.

    I just posted the rules simple as they are. I am on a long weekend vacation. Work finally slowed down to get out of town. You have to guess where I took Mrs. Train on the gold wing. Click on the link below and have fun!

  6. 4 Years, where's the project today?

    Where have I been hiding the last couple of years? Dunno, been lurking, but it doesn't matter. This is the 4th year of the HO Scale project that started the layout rebirth. A lot has gone down and here's where the project is in a nutshell (Beginning with stuff to be done).

    First off, my 10-6 Burlington Sleeper, GN Big Sky Blue Vista Dome and GN Empire Builder Omaha Orange Observation (due out 28th April) have all been replaced with Walthers Proto Models. Appropriate window tinting, ...

  7. Locomotive Design Considerations From a Western Colorado Conductor

    Some insight on what one GRJ conductor considers the better locomotive overall, GE vs EMD

    The SDs have a tiny desk that make it nearly impossible to put up my feet during a trip. But the cooler is within easy reach and I don't have to get up to get into it. Here, in Grand Junction, we rarely see them in unit coal service, so there

  8. 'No Hands Bridge' Becomes Landmark

    I was at and part of the dedication on Sunday the 23rd as a member of the Mountain Quarries 100th Anniversary Committee. A nice one hour presentation and unveiling of the new plaque took place as well as a group photo taken on the bridge. I also took several photos and will be posting then in an upcoming update to the Foothill Rails site.

  10. Picture TEST

  11. BlueTrain Distance/Speed Measurement Setup

    The two pictures show the setup for testing the measurement of distance and speed by the new "Train Brain". There is a LED on PWM motor speed control that indicates the relative commanded motor speed. The flywheel of the motor has two of its four quarters darken, so that it produces two counts (or triggers) per revolution form the IR senor. The "Train Brain" counts these pulses so that it can calculate and control motor speed and measure distance traveled. Good bye Back-EMF; ...

  12. BlueTrain Source Code "Readme"

    ReadMe for BlueTrainTransceiver

    The purpose of the BlueTrain project is to develop a Bluetooth transceiver for model locomotives that is controlled by a Bluetooth enabled computer or iDevice. This project is open-source in the hope that it will result in the improvement of model locomotive control.

    This folder contains the "BlueTrainTransceiver" program in the form of an Atmel Studio 6.1 C project. The development target is a Nano board (Atmega328p).

  13. Bluetooth Locomotive Transceiver I/F:

    I have completed debugging the embedded transceiver software on a simulator, so here is a look at the interface file for “BlueTrain”.

    [Looks like this is not the best place to post code. There seems to be automatic removal of multiple space & tab characters.]

    Next up a Windows control program (“BlueCommand”) for “BlueTrain” and testing on the hardware.
