Measuring growing vegetables with internet of things...
I started to measure environment variables like; temperature, barometer, hygrometer, light brightness, dominant colors and much more and report it online.
Here you can see my real-time demo: https://cosm.com/users/willyp. Please note that there are moments that I am upgrading the devices. Today I am starting to make the setup more suitable for battery operation. I`m implementing processor sleep functions and disabling external devices to conserve energy. I want to have the sensor transmitter working on a double CR2032 battery for at least a year long.
Currently in the unit there are tomatoes, paprika, carrots and beans.

I am still alive!
Wow, I looked at my blogspot account and mentioned that my last blog was over 2 years ago already!!!
Looked back at the last two years, I've got quite a lot of reasons why I did not post anymore to this blog: I really had no time left to do that!. Past years, I've lost my dad, bought a new home (and completely changed it), finished my study and much more.
But since some time I had some spare time left in the weekends so I started to pickup my hobbies again... :) .
I'will keep you posted!
By the way, I finished my KeaDrone project. It has changed a bit from helicopter to a Quadcopter design but I have it flying!! :D Already have some great pictures taken with the copter from some altitude..... :D
