Motorola Atrix setup - Rooting your Atrix on Gingerbread 2.4.3

By Tim Naylor -
So, I got a new phone and of course I can't just leave well enough alone so here are a few tips and tricks for my atrix setup
Prerequisits:
  • motorola fastboot (win32/64 or osx depending on your os of choice)
  • Android sdk installed and adb working
  • proper drivers for your device
Assuming all of that is done there are a few setup steps necessary to enable your device to speak to adb:
  1. Plug in phone via micro USB cable, wait until it is recognized by the OS.
  2. On the phone, pull down the alert menu and choose USB connection
  3. Make sure that "NONE" is selected
  4. Open settings->applications->Development
  5. Make sure that USB debugging is checked
ROOTING your Atrix,
this may seem to be overkill, but for backups like ClockWorkMod, battery reset (if like me you did the Gingerbread update without a full battery), Titanium backup, etc. this is a necessary step.
  1. Restart your Atrix in fastboot mode (restart while holding the volume down)
  2. When it says "Fastboot" push the volume up button, it will then say "Starting Fastboot protocol support"
  3. Push an updated preinstall.img to the server
    1. Open a command prompt
    2. cd to your fastboot directory
    3. Type fastboot flash preinstall preinstall.img NOTE: If your fastboot executable is named moto-fastboot or moto-fastboot-osx then change the name of the exe as needed. if preinstall.img is not in the current directory then include the full path to preinstall.img
  4. Now reboot your phone by typing fastboot reboot
  5. Once the phone reboots, move to your adb directory and run adb shell
  6. Now we need to be the Root user and bash is nice so type /preinstall/dosu and hit enter to switch to root.
  7. The /system mount is read only at this point so type /bin/mount -o remount,rw /system and hit enter to change it to read write.
  8. We want to copy su (switch user) to somewhere we can use it so type cp /preinstall/su /system/bin/ and hit enter.
  9. We need to make sure it is executable so type chmod 6755 /system/bin/su and hit enter to set up the correct rights.
  10. Now we need an app to manage root access so type PATH=/system/bin:$PATH pm install /preinstall/Superuser.apk and hit enter (pm and it's fellow components are in /system/bin which is not on our path at this point).
  11. you have successfully rooted your phone!

HomeAssistant via docker on a Mac

By Tim Naylor -
Several weeks ago I switched to docker on a mac mini under ubuntu server.  I saw in the forums some people wanting to do it on OSX and I was about to write this article so I agreed to do it on OSX instead of Alpine Linux. It did not go as planned. I ran into significant issues, but today I sat down to get it working. Then I found out that someone had already updated the documentation here:  https://www.home-assistant.io/docs/installation/docker/ so that should be the source of truth. Hopefully this will be a little more straight forward since there is no intermingling with other operating systems and some assumptions in the documentation are called out expressly. First download docker here  https://store.docker.com/editions/community/docker-ce-desktop-mac you will have to create an account in order to do so. Once installed, fire up docker for the first time (from the applications directory, or launcher). follow the instructions in the wizard and log in with your docker accou

Flashing my tuya switches with tasmota

By Tim Naylor -

This was an exciting adventure. I got these switches for $10 from someone who failed to make them work at their own house. They are JMH CD303 Tuya switches.  You can get them on Alibaba here:  https://www.alibaba.com/product-detail/2018-US-Smart-Switch-WiFi-Tuya_60764782124.html?spm=a2700.details.maylikever.8.287e3376iYLvTg  Initially I was just going to use the https://github.com/clach04/python-tuya method to integrate these into HA with local support. but then I got looking at that chip and it looked like an ESP8266, so I did a little digging. I was able to flash the Tuya TYWE3S module with Tasmota. Travis from digiblurDIY updated the Tasmota wiki with all the relevant information: I soldered up my TYWE3S just like he did here: The switches work perfectly with following settings: They need to be set to switchmode# 3 in order to maintain the state.  Switchmodes 0-2 acted like switchmode 7 usually does. With some tiny tweaks to the housing, it fits sideways

How I put Tasmota on my NodeMCU board and why I love them so much.

By Tim Naylor -

I love NodeMCU chips! I love that everything is already there: wifi, enough onboard memory to actually do stuff, easily programable with Arduino ide once you have a driver (driver downloads here: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers ), and my favorite part, you can power them with anything from 3.3-12 volts so lots of power supplies work for them. I especially love the 12E or the 1.0 it is a little narrower, fits on a breadboard, super convenient! So far the only downside is that the output is only 3.3 volts (but that is true of all of the esp8266 boards), and the pins can be a little confusing ... D4 is GPIO2 which is pulled high at boot, and will cause boot failure if something is pulling it low at boot ... just lots of stuff to remember  HMMM that feels like another article in the making, for now here's the gist: What did I do to get it up and going?
