  1. Sierra Angels Camp Branch

    As of late, it seems that the Angels Camp Branch of the Sierra RR had become the "in" thing to explore and document. Well lets just say, I wasn't to be left out. Taking advantage of the low water in the lakes, my girlfriend and I recently headed to New Melones Res to do some exploration of my own. I have previously visited this part of the line and built a page for the results on Foothill Rails but the drought in California has given me a unique opportunity to check out what is below ...
  2. Bluetooth Locomotive Transceiver? Rectifier–MotorControl–Ta chSensor




    The Rectifier–MotorControl–TachSensor circuit is ready for some testing (I hope). Thought it would be a good idea to post the pictures before starting the testing. I may well cook the whole ...

  3. Bluetooth Locomotive Transceiver: DRV8801 Board

    Nice to get back to the original purpose of this blog; working on BlueTrain. I have gotten the motor-control board working on a breadboard setup. It so nice to have help form a knowledgeable tech-support; big thanks to Brandon! But, I managed to cook my only brain (Nano board) when I connected it up to the main DC source. I was going to quickly test the PWM from the Nano running a motor through the motor-control. In my excitement and hurry, I had left off the 100 ohm resistor between the DC ...

  4. New Open-Source-Bluetooth-Train-Control

    I am making the first post visible because it contains some important information that would not fit in the description of the Group:

    Initial Moderator RT_Coker

    This group is “moderated”, that is open to members how are interested in contributing to the development of Open-Source-Bluetooth-Train-Control. This group includes and encourages the participation of manufactures and members of other open-source organizations. It discourage (and will limit were feasible) the ...

  5. New Open-Source-Bluetooth-Train-Control

    All,
    I have created a group called “Open-Source-Bluetooth-Train-Control” whose purpose is to encourage, promote, and develop Open-Source-Bluetooth-Train-Control. If you (individual or organization) are interested in possibly being a contributor, you can check it out here: http://www.trainboard.com/grapevine/...hp?groupid=125

  6. “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 ...

  7. “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 ...

  8. “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 ...

  9. 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 ...

  10. 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.

  11. 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/.

  12. 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 ...

  13. 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).

  14. 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 ...
