  1- I'd like to build a simple alarm clock using Omega2+.
  It would display the current time in a 16x02 common "arduino display" (using Expansion board's GPIO), a common buzzer and blinking the Expansion board's built-in RGB LED.

  2- Build a level gauge for a tank.
  Where it can distinguish other and "heavier" liquids (in general, matte one) than upper water liquid (transparent one), measuring height of the "heavier" liquid without reporting the water height, just the other liquid.

  @Lazar-Demin thanks! That helps!

  btw. is there any project going on to write a Ruby wrapper for GPIO interaction?

  Still not watering anything, but ...
  I went ahead in Ruby and found myself writing a 'wrapper' to switch my valves (basically GPIO's). I could contribute if there is any project.

  See GitHub Repo

  stdin, stdout, stderr = Open3.popen3("fast-gpio set #{@gpio_number} #{v}") if stderr.gets raise(OnionGpioWrapperError, stderr.gets) end

  I have a bot with 70K subscribers on Telegram! Why am I not able to broadcast a message to all of them on time?! I mean if I go ahead and broadcast a simple message, God knows when it will be delivered to all! Can anybody guide me on this issue? what should I do about it? Do I need a more powerful server or its not related to my server's configurations directly?! Thanks

  So here is my solution:

  First I write incoming command to a file called task:

  mosquitto_sub -h SERVER -t '/TOPIC/' >> task

  then I read the file, and execute the last command:

  NUMOFLINES=$(wc -l < task) while : do NEWLINE=$(wc -l < task) if [ "$NEWLINE" -gt "$NUMOFLINES" ] then NUMOFLINES=$(wc -l < task) LASTCOMMAND=$(tail -n 1 task) eval ./$LASTCOMMAND fi done

  the Message of the topic equals the file name to execute.

  This is working just fine for me

  @Leif-Bloomquist thanks for the project write-up. it looks very simple yet effective. i also have a leap motion device and would love to put it to use as it has been in a box for over a year now. looking to read the code you have this weekend. good luck on continuing with the vehicle. looks fun. may have to do something similar with a omega on a arduino dock.

  @Jonas-Belink You can check out the steps in the GitHub repo's readme file to see how to setup the server code on a dedicated server somewhere (AWS, DigitalOcean, etc).

  If you just want to add your device to our existing temperature.onion.io server, see https://github.com/OnionIoT/Onion-Sensor-Server#adding-your-device

  Which packages did you install on your Omega? Do you have example code available?

  Hi all
  Good news. I migrated original code successfully to work on Omega2!
  See https://github.com/h0l0gram/omega2-checkHumidity for binary and source.

  Make sure your Omega2 has firmware >=0.1.10 b160 or it won't work.

  We are trying to do this as well. Part of the "problem" is the fact that the Omega has no native video capability. We looked at the idea of creating an HDMI shield for it, but that is beyond messy.

  @Nicolas-Bernard the GPS module is the onion USB version - the others modules are arduino nano (to count encoder pulses from start up as omega takes too long to boot), accelerometer and real time clock

  @Anurup-Kankanhalli thank you! :) the omega is on the expansion board and wired to veroboard from the onion proto board
