Domoticz on PI with relay

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

Linux, Raspberry Pi 31 Comments

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

Linux, OpenELEC, Raspberry Pi 116 Comments

“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

Linux, Raspberry Pi 158 Comments

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,…

Raspberry Pi 19 Comments

  Note: There’s a newer version of this entry – updated with latest tests, much easier to install: https://blog.jokielowie.com/en/2017/01/sledzimy-samoloty-cz-2-ads-b-i-mlat-najtanszy-odbiornik-dla-flightaware-oraz-flightradar-24/. Last time I’ve shared with you the Raspberry Pi “computer for a buck”. Unless you’re are learning Python or playing Minecraft – or better – you’re already bored – I have a new thing fro you. It’s a very nice idea that you can use as your graduation or school project – and it’s all about tracking airplanes high in the sky. From hardware point – you will need a DVB-T/DAB USB dongle…

Raspberry Pi Leave a comment

 There’s no doubt that non-profit organization behind http://www.raspberrypi.org/, the $25  computer (well let’s just say $35 + some xtras) had a huge success and is the next big thing for every computer enthusiast. Raspberry Pi is a full blown computer based on the ARM  architecture  that allows to run different sorts of operating systems. Today we have a choice of many Linux distributions, and the one to start and one to stay with is the Rasbian, based on another famous Linux distribution – the Debian. This little computer is designed…
