Last time we build a simple SMOG sensor, do it's high time to add display (OLED) and to verify the SMOG measurements – the environmental sensor – as we know that humidity over 70% can add up to the SMOG.

Recently, we built a smog sensor which measures PM2.5 and PM10 ppm particles common in SMOG. This time let’s focus on something easy to do, without deliberations on extending life of the sensor. The Nova Fitness SDS011 (also versions 018 or 015) has proven to be quite accurate, with a good life exp...

We already do know how to install Domoticza. But how easy is to control heating in your house/flat? After full season of testing radiator control – I can recommend a very interesting and useful heating control system that you can setup in your home or apartment. All just by means of adding radiator thermostats with Z-Wave radio.

PLNOG is a conference held in Warsaw and Krakow twice a year. This is the place where IT and telco people meet. Last time I spoke about some of my experiences in building small devices, listen if want to (Polish only):

Proper supply of power is a very important part of our SBC (Small Board Computers) projects. Power supplies with too low current efficiency, instability and lack of filtration – often lead to accidental resets, lack of sensor readings or simply unstable behavior of SBCs. One of the solution is to modify the power supply from Microsoft console – XBOX 360.
WARNING: We will work with high currents and high voltage, which requires basic knowledge of electrical engineering. The author is not responsible for accidents and everything you do – you do at your own risk.

We already know how to track airplanes using DVB-T USB dongle and Orange Pi or Raspberry Pi. Let’s move on to a new system that allows tracking of light aircrafts:

• Gliders
• Helicopters
• Baloons
• Smaller airplanes

LARM – is a collision avoidance system for light aircrafts, populariz...
