  1. “Bluetooth Accessory Decoder”

    “Bluetooth Accessory Decoder” will be a follow-on project to “Bluetooth Locomotive Transceiver?”. Because of the recent activity in the use of “patent pending” (that I personally consider miss-use), I think it best to announce this project in an effort to try and protect its open-source use!

    The simplest use of BlueCommand is as a single unit with the user manually responding to the accessory-commands, such as changing the direction of a turnout. When Multiple BlueCommands are connected ...

  2. “Bluetooth Locomotive Tachometer”

    “Bluetooth Locomotive Tachometer” will be a follow-on project to “Bluetooth Locomotive Transceiver?”. Because of the recent activity in the use of “patent pending” (that I personally consider miss-use), I think it best to announce this project in an effort to try and protect its open-source use!

    The initial installation of the Tachometer consists of a Tack-Wheel-Label on the fly-wheel with IR-source-sensor. A Rigid-Tach-Wheel will be developed for some installations where the Tack-Wheel-Label ...

  3. “Bluetooth Locomotive Location Display”

    “Bluetooth Locomotive Location Display” will be a follow-on (add-on) project to “Bluetooth Locomotive Transceiver?”. Because of the recent activity in the use of “patent pending” (that I personally consider miss-use), I think it best to announce this project in an effort to try and protect its open-source use!

    Because BlueTrain has the ability to stop at a designate-know-location on the track and send that information to the iDevice along with an accurate and current scale-speed, the ...

  4. Bluetooth Locomotive Sounds?

    “Bluetooth Locomotive Sounds” will be a follow-on (add-on) project to “Bluetooth Locomotive Transceiver?”. Because of the recent activity in the use of “patent pending” (that I personally consider miss-use), I think it best to announce this project in an effort to try and protect its open-source use!

    Because BlueTrain has the ability to synchronize chuffs and send that information to the iDevice along with an accurate and current scale-speed, the iDevice (or PC) application BlueCommand ...

  5. Bluetooth Locomotive Transceiver? DRV8801 Board

    I bought 2 more of the motor-control boards, and managed to get the pins solder in without destroying the board. It is great to be able to watch a web video of somebody doing it successfully!!! Got the board setup on a breadboard, and now I can produce heat for a limited time.
    I am almost sure it is not this breadboard setup. It must be something about using the DRV8801 board that I have gotten wrong.
    Time to do some more researching and thinking.

  6. Bluetooth Locomotive Transceiver? Pre-H/W S/W Release

    I have been having trouble with the motor-control board. It is probably my poor soldering (or my misunderstanding of how it works). Because of the H/W delays, I “released” the “Pre-Hardware” version of the software at http://spaces.atmel.com/gf/project/bluetrain/frs/.

  7. Unsuspected Train!

    When I showed up to work this past evening, I thought it would be pretty much a regular night of work. I'm in my truck, starting to do my paperwork, when I hear the nearby crossing gates ringing. Now, trains where I live are few and far between right now, so I was excited to see one and ran back to the tracks too see what was coming. First were a group of three bay covered hoppers (including a Pillsbury car!), then the regular Northwestern Pacific gen set loco coupled to a (get this) clean, unpatched ...

  8. Bluetooth Locomotive Transceiver? Motor Problem

    I got too excited when I found a related web site and managed to break a tab off the Mallet’s motor. I was in the process of wiring the rectifier, motor control, and tachometer sensor in the engine. Old eyes and shaky hands have their limitations.
    Anyway, it was great to see that an iDevice direct-Bluetooth train control board exits (see this apparently new web site, http://www.bluerailtrains.com/intro.cfm).

  9. Michigan-California Lumber Burns!

    Take Advantage of Opportunity

    That's the theme of this blog. Take advantage of opportunity.

    Once again, it's been some time since I've written a blog. For that matter it had been some time since I'd gotten out to railfan. Life, the loss of my old computer, and work updating my newest site, CLASS III Shortlines, have kept me away for a bit. No worries, the stuff I lost on that pc is totally recoverable and much will make up future Foothill Rails updates when I get ...

  11. Bluetooth Locomotive Transceiver? Documents

    The development version of the hardware is almost ready to be connected up and tested. I thought it would be good to make some preliminary documentation available. You can find PDF versions of the “BlueTrain IF Manual” and “BlueTrain Dev HW” here: http://spaces.atmel.com/gf/project/bluetrain/docman/

  12. Bluetooth Locomotive Transceiver? Motor Driver

    IMG_2979.JPG
    De-braining and reverse-engineering the Atlas decoder board was going to be too difficult and problematic. Had some help finding this >$5 DRV8801 motor driver that is well documented. (Thanks Ray Jones!) So next up will be connecting and testing this motor driver. After that I will attempt to reduce the Atlas decoder board into just a DCC to motor-power board that also provides +5 volts DC.

  13. Bluetooth Locomotive Transceiver? Tachometer Wheel

    The IR sensor is now getting a great signal reflection from a tachometer-wheel. The tachometer-wheel is made from “silver” foil labels with a pattern printed by a laser printer. The idea to use labels to make tach-tape came from “gunrunerjohn”. Thanks!
    Here are some examples. (The poor quality of cutting comes from not-so-good eyes and a shaky-hand.)

    I am currently looking for help getting a “brainless” DCC decoder board for connection to the Nano328 board. (Trying to avoid ...

  14. 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 ...
