Tracking gliders, airplanes, helicopters and baloons, part 3 – FLARM

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 FLARM – is a collision avoidance system for light aircrafts, popularized and approved by EASA, gaining traction, used mainly on gliders in Poland and Europe. We’re not going to use it to avoid collision – but to receive position and track light aircrafts – so we can share them on the…

Raspberry Pi B+ with Neoway GSM M590 module

Raspberry Pi and GSM network- sending SMS, connecting to the Internet (IoT)

This time I’m going to connect to our Raspberry Pi a GSM module. Why? Internet of Things, in short IoT, as it was noted at Krakow’s PLNOG17  by Marcin Aronowski involves and depends on the network which should be easily accessible, and the very essence of IoT is the energy efficiency. Perhaps, he said, 3G will go away but 2G but will still remain. And we do not huge pipes – just enough bandwidth. 2G connection is still the cheapest in the implementation (also due…

Raspberry Pi B+, ds18b20, ESP8266

Domoticz part 2: WiFi remote thermometer for weather station, dual digit precision – it’s ESP8266 for beginners

Last time we installed Domoticz, and soon we will move to Z-Wave, but first – let’s take a look at fantastic little gadget: ESP8266 What is an ESP8266? ESP8266 (also called  ESP here) is a SoC – System on a Chip, which in our case is – CPU/RAM/FLASH with GPIO and WiFi interface – so another mini komputer with wireless interface. You can think of it as scaled down version of Raspberry Pi, less power hungry, but with own WLAN and a lot (minimum 2)…

OpenVPN Raspberry Pi – split-tunnel with Internet access

Would you like to connect from any place, usually using open WiFi network in town, at friends or airport – with your’re own home network? Virtual Private Network (VPN) is here to allow you to log-in securely to your home network, with additional perk of using it to get secure Internet access. What will you need? Hardware: Rapberry Pi (A, A+ or B, B+, 2, Zero) Home Router with Port Forwarding or Virtual Server support – any will do Software: Raspbian – standard Linux distribution for…

Domoticz on PI with relay

Domoticz part 1: Relays, magnetic sensors, Wake-on-LAN and Z-Wave – Domoticz with Imperi Home serving your house

This entry was initially about single and simple purpose: how to quickly develop a solution that would open gate or garadge door by simulating the remote’s operation mode – pressing a button – but using smartphone, tablet, web browser, app. Domoticz is such an overkill and also blessing for such project – that it evolved into a lot of small sub-projects – more or less andvanced. Direct inspiration was another entry by colleague on  MalinowePi Facebook group – Roman Kubat, who showed ImperiHome. This application has great interface but…

Light effect for any device with Video output based on raspbmc or OpenELEC and RaspberryPi

“Good news, everyone!”. If you succeeded in creating light effect using the previous entry:  https://blog.jokielowie.com/en/2014/02/efekt-swietlny-dla-media-playera-operatego-o-raspberty-pi/ you must’ve noticed that it’s limited to the content being played by raspbmc or OpenELEC. Luckily thanks to constant development by hyperion’s creator (tvdzwan) we’ve just got ability to use the effect with other devices that have video output the http://pl.wikipedia.org/wiki/Composite_video. Usually modern STB, Blu-Ray player or amplituners sport a SCART output or the yellow colored ‘Video’ output. What is important – they allow both HDMI and Composite video outputs to…

Pi with Light Effect

Light effect for Raspberry Pi based media player – raspbmc or OpenELEC/LibreELEC

Raspberry Pi can be easily used as media player. We can choose from many variations, but the one I’d like to focus on is Raspbmc based on XBMC. Raspbmc with hyperion has ability to drive RGB LED strip or daisychain using Raspberry Pi. The important part is that it will lit the RGB LEDs accordingly to the screen borders in realtime. It’s used to make the visible part of the picture more vivid and extend it beyond the display, and it’s simply quite cool: So,…
