“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
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.
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/.
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
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).
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

Some people cannot see the pictures in my previous blog posts. So here they are:
>$5 DRV8801 Motor Driver:
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/
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.
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
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

Some new pictures of A-unit's current status:
Now the B-unit has to be finished accordingly and then setting of thousands of rivets will start...

An open house is planned at the Northwestern Illinois Model Train Club for Saturday June 21st, from 10a.m. to 4p.m. We have an “N” scale running up stairs on the main floor and “HO” scale running in the basement. The model train layouts are located at 101 Main Street Chadwick, IL
We have two different size working layouts. The “HO” scale layout has 3 levels covering
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!
Pass the word we cant let Boxcab win al the time LOL
