Google Home Goes Multiuser

Google Home has rolled out multiuser functionality. Despite an initial glitch, it seems to work well.

Each member of your household records their voice saying “Hey Google” and “OK Google” by kicking off a dialog on their Android mobile device. They then get access to their personal calendar, music content, and other personalized services to follow. Once enabled, each user can voice query, “Hey Google, what is my name?” and Google Home knows!

I was the initial owner of Google Home when we set up our two devices. After Tina enabled her profile, we found a glitch where Home did not know who I was any longer. It kept referring me to my Google Home app to enable multiuser functionality. But, it took a few days for Home to offer me that option within the app.

Yesterday, when I tried to listen to some content, Google Home complained that it didn’t recognize me and again asked that I enable multiuser. This time, the option was present and I was able to complete the setup.

Running BMXTG on Windows 10

I’ve been able to run the Brandmeister XTG Dialer on Windows 10 by following this procedure.

Visit the PyGTK FAQ page and fully read 21.1.

I installed the following items referred to in the FAQ:

Python 2.7.13
PyGTK for Microsoft Windows using the all-in-one installer

Run a Windows command prompt as Administrator.

cd \Python27
python -m pip install -U pip setuptools
python -m pip install -U requests

Exit the Administrator command prompt and then open a command prompt as a regular user.

cd %AppData%
mkdir Python

Copy bmxtg-v1.2.zip into your %AppData%\Python directory and unzip.

Create a desktop shortcut to bmxtg.py. The “Target” should be “C:\Python27\pythonw.exe bmxtg.py” and the “Start in” directory should be “%AppData%\Python\bmxtg-v1.2”.

Be certain to review and follow the configuration notes in the README. Then, you’re ready to fire it up!

BMXTG 1.2 Released

The Brandmeister XTG Dialer (BMXTG) has been updated to version 1.2. Enhancements include automatic download of the masters address list and automatic download of talkgroup IDs and labels. Any talkgroup label may be changed through use of the talkgroups.conf file. Be sure to review the README file for changes.

The changes will make BMXTG easier to configure and the user no longer needs to be concerned about IP address changes of the BM servers. A simple stop and start of the program will refresh the server list and talkgroup list automatically.

I’ve also updated the DV4mini Raspberry Pi 2/3 image to include BMXTG v1.2.

Tracking North Korean Numbers

My Aussie mate, Mark Fahey, has spent a number of years studying the Democratic People’s Republic of Korea.  He passes on the following information about North Korean “spy numbers” stations:

“The Pyongyang numbers (designated V15) have either become less regular or changed their schedule since March. Its been a few months since I have personally received them – but I also haven’t been specifically tuning in for them lately so maybe I have simply missed noticing a timing change.

“If you want to find the North Korean numbers, they are read out in a block between songs within the regular programing of the Pyongyang Pangsong radio station. The choice of music immediately before the number block seems to indicate which recipient agent the transmission is directed to. For Agent 27 “We Will Go Together with a Song Of Joy” is played, whereas Agent 21’s song is “Spring of my Hometown.”

“The announcements typically take between 5 to 10 minutes to read dependent on the number of digits passed. The transmission schedule is variable; in early 2017 the broadcast alternated with a cycle of one week on Thursday night at 12:45AM Pyongyang Time (1615 UTC) and the following week on Saturday night at 11:45PM Pyongyang Time (1515 UTC).

“Pyongyang Pangsong can be heard on these shortwave band frequencies (it is also on MF & FM on the Korean peninsular):

3250 kHz Pyongyang 100KW Transmitter
3320 kHz, Pyongyang 50KW Transmitter
6400 kHa Kanggye 50KW Transmitter”

RetroPie, A Tasty Gaming Platform

Retrogaming, the enjoyment of older computer based games and platforms, has been growing in popularity. I was intrigued a couple of years ago when, at a Vintage Computer Fest, I saw a multigame platform with hundreds of game ROMs copied onto a single emulation device. I had been wondering what the old games would look like connected via an HDMI input as opposed to the old low resolution RF transmitter method.

Then I came across the RetroPie project. RetroPie is a framework, delivered as an image, that allows you to run a number of game and computer system emulators on a Raspberry Pi. RPi models 2 and 3 are much better than older versions for this application. It is very simple to install and I was even able to use an old Colecovision controller to play Donkey Kong, Ladybug, and Carnival.

To connect the old controller, I came across a device called the Vision-daptor. One side sports a DB9 male connector, the other a USB B jack.  It arrived just a couple of days after my order.  The RPi recognized the device as a joystick controller without adding any additional drivers.

The Coleco emulation is handled by an optional component called CoolCV. CoolCV will also run under Linux, Mac and Windows. If you use a controller, rather than a keyboard, you may need to make some changes to key mappings in a configuration file.

There are plenty of sources for games online, but remember that games may still be covered by copyright. Some folks copy the contents of ROMs that they have purchased allowing them to play games for which they no longer have a gaming device. This requires some specialized hardware.

If you do download games via the internet, keep in mind that some sites may be vectors for the transmission of viruses and other malware. Exercise caution while you kill off those space invaders.  And the games do look great on an HDMI monitor!
