Don’t have her quite yet. She is only 4 weeks old in this picture so another 4 to go, but this is the one. She will join our other two, Zack and Molly.

Blu Phone Sends Bluetooth to control Aristo U25B with Soundtraxx TSU-4400. 2200 mAh Lipo battery, Full range TangBang speaker with passive radiator. Rewired the lights for LEDs. Good speed and power on the U25 at 14.8v.

Since my Python Apps do not work on any Android Version greater than 6, I am working on re-writing them in Android Studio. At first I was not particularly thrilled that I had to re-write everything but now I’m starting to really like Android Studio. I’ve decided to add additional functionality so that I only need one App. The name of the bluetooth device (the locomotive name) will now allow the app to ‘configure itself’ when the locomotive is chosen on the phone. If the locomotive uses a TSU-4400 SoundTraxx decoder, the appropriate screens will come up for that. I am also going to allow the main screen to be programmed, change the icons and what function codes are associated with them.

Adding the Bluetooth Controller to my Chessie U25B. Bluetooth board, Soundtraxx TSU-4400 and DCC Amplifier. 2.2 inch tangbang speaker with passive radiator. Servos on the couplers. There is a 2200mAh lipo in the fuel tank.

I already had this locomotive hooked up for the most part, I was driving it with my Xbee Board so I swapped that out with the Bluetooth version. I also replaced a tiny speaker I had in the front with the one in the picture (on the left). Much Much cleaner sound mix. Bells and horns out of the front and the prime mover going to the back speaker with the passive radiator.

Here it is out on the layout, ready for a test run.

Here is a video of some basic testing. It still needs some tweaking on momentum and motor voltages. Please forgive the poor video and sound quality- my nice camera died and this is my backup.

I also ran my latest version of the Generic DCC Phone app. Works quite well now. The QSI is a tad on the finicky side however so I made a very small mod to the firmware in the Bluetooth Widget. Once I back test that on the other decoders I’ll roll it into the firmware release.

You can find all of my Android Train Control Apps on Google Play.

Something different, a gadget for the airplane. This is my incarnation of the Stratux open source ADS-B unit. It uses a Raspberry Pi3 along with a couple of high gain antennas, two radio receivers and a GPS unit to snatch weather and traffic data out of the air. For free! Can’t beat that. I think I spent a little over $100 on it, but I already had the Raspberry Pi3.

I also have an AHRS module plugged into it which should give me a basic Synthetic Vision system. Now I just have to figure out how to mount it ‘semi-permanent’ into the airplane. It has to be removable and used for ‘situational awareness only’ to be legal.

But one thing at a time. I’ve tried it with my two BLU phones and also my ASUS 7 inch tablet. So far so good. Works really well. Just plugged all the parts together, flashed the SD card with the free software and it comes up and runs. I’m trying out a couple of Android Apps that will work with it- they overlay the weather and traffic data on a current FAA sectional moving map plus let you do other cool stuff like plot out your file plan, get airport info and such. Neat.

Got all the parts and pieces together (well almost) and did some testing outside on the layout. I was very impressed with the range, I have a new $50 BLU Studio phone and I’m getting a good 100ft. So far I have not seen any of the problems mentioned by other users of the TCS Wow 5amp. I did talk to tech support at TCS and they indicated that there had been some hardware changes to the 5amp since it was first released. He didn’t go into what they were and was not clear if the firmware changed or not. Mine is pretty new, I got it from RP about a month ago. He said there was no way to read the s/w version so I don’t know exactly what rev of firmware is in there. That is obviously on purpose for whatever reason.

But so far, I really like this decoder. Crisp sounds and I like the brake feature. Very cool that it ‘coasts’ when you shut down the throttle.
