Dragonboard 410c post install tasks

Now that we have the software all installed, let's actually get mythtv running by setting up our environment:

First mythtv backend requires it's own user so let's add it:
sudo useradd --system mythtv

Now we need to tell mysql about time zones:
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql

It is safe to ignore the warnings from not being able to load some zone info tabs.

Mythbackend will create our database and upgrade the previous mythconverg db schema to the latest version so let's run it:
mythbackend

Note that it will auto shutdown and any further attempt to run it will end in an error saying no capture cards are defined in the database.

Next it's time for some fun gui ease.  Either connect a keyboard / mouse /monitor and run mythtv-setup from the command line or run it via a remote x screen by clever use of ssh (i.e. something like this: ssh -X linaro@000.000.000.000 /usr/bin/mythtv-setup).
Setup your backend for either your capture card as described in https://www.mythtv.org/wiki/Configuring_MythTV or if you're like me and are using a cable box and a v4l usb encoder, then select v4l as your capture card, and setup your ir blaster to change channels.  Use escape to exit the full screen mythtv-setup.  Also note that you should set the default mythtv directory to /media/externHD/<somefolder> or you run out of space fast!
When everything is happy, and you can exit without setup giving a friendly error message.  It's time to set the backend to auto launch:
edit /etc/rc.local and add the following line:
/usr/local/bin/mythbackend -d --logpath /tmp/ --user mythtv

Now follow the normal mythtv frontend setup:
https://www.mythtv.org/wiki/Configuring_Frontend

Hook everything up with the hardware in place, and declare success of a low power feature rich mythtv dvr system!

Next we'll return to our normally scheduled programming tutorials for helping out the blind, practical project and Vulkan android studio plugin development with Qualcomm's Vulkan SDK!
After all that, I plan to add to this minimum solution by adding voice recognition AI assistant, basic home automation, and security.  Stay tuned!

Drone VR Software Architecture

Finally we're at the point in our opus VR drone project that we need to look at the software. If you're following along, I have the Hardware drone built, using Snapdragon flight . To review, we have knowledge of how to create a project in Android Studio that can target Snapdragon Flight for deployment. We know how to utilize the Daydream controller to build an arm model . We also know how to setup a VR project in Android Studio . Finally, we know how to communicate with the Snapdragon flight controller. So, if we put it all together, we only need to figure out how to program the controller aspect of the Flight. Thankfully there's rich support available for Flight that allows us to have full C-API control over both the ESC and the controller board. It is provided through the navigator api library . Now let's talk about the overall design. I envision four main modules: VR Controller App interfaces with the user gets positional updates and issues commands de

Soldering new connectors for the drone

If you're with me so far, in our Snapdragon Flight VR build, you might have noticed that the connectors that come with the motors do not match the connectors that come with the Snapdragon ESC. This means we need to replace the connectors so electrons can flow and power the motors. Remembering that the whole point of this is to get electrons to flow will make the concept easier. Copper is a conductive material, that's what wires are made up of. Solder is a metal material that is highly conductive with a low melting point and solidifies fast. So the idea is we want to use the molten solder to join the wires to the new connector. I personally favor damaging a cheap motor to damaging an expensive ESC, so I opt for doing the work on the motor connections themselves and highly recommend this path. While the minimum you'll need is 4 connectors, I am really good at making mistakes, so I wound up getting 10. The first step, is to cur the old connector off. Grab a pair of w

Build Snapdragon Flight Drone

In order to have a VR Drone, we must start building a real physical Drone. Snapdragon Flight offers a great light weight powerful platform we can do a lot with. While most home built Drones are built with very custom specs; I felt it necessary to make this very approachable by ensuring the Drone is built exactly as the specs outline. Our's looks slightly different, but hey Drone time! Let's start with the parts the Drone needs: Allen Wrench Hex Key Set Dynamite 5 pc Metric Nut Driver Assortment Generic M2.5 Nylon Hex M-F Spacer/Screw/Nut Assorted Kit Loctite Heavy Duty Threadlocker 2x clock wise motors 2x counter clock wise motors ac converter for battery charger battery charger Battery ESC (to control the 4 props) Frame Kit gps antenna 4 x DF3-3P-2DSA connector Wifi antenna Grey props: x2 Red props: x2 Before jumping straight into working with the hardware, a small house keeping task must be preformed. There's a small problem, If you have big
