Build a Speaker: Monacor Frame

Moving to a new apartment made a long fostered dream become reality: My own office/geekery/game/cinema cave, furnished with working desk, game consoles, digital projector, sound system and sofa.

Having a room with rectangular outline, I planned to use one of the smaller walls as projection screen. This made the decision for speakers not as easy as I wished: Nice standing speakers were too space consuming, smaller wall speakers (as the Canton GLE-417) are lacking power when used as front speakers.

Hours of research and conspiring with a gadget-affine friend ended finally in the decision to build my own speaker set: The Monacor Frame is a slim wall speaker using one chassis for high- and one for mid-to-low range frequencies. A subwoofer (already owned) completes the 2.1 system to cover the full frequency spectrum.


Use a Logitech Harmony Hub with Ubuntu & Plex Home Theater

The Plex Media Server provides an awesome feature set for managing and enjoy media in the living room. Plex Home Theater is a beautiful client available on all major operation systems and allows access to the complete media library through a fancy UI.

I love the programmable Harmony universal remotes by Logitech. When building up my movie and game room recently, it was no question for me to use one of them to control my device zoo.

Since the latest revision of Logitechs remotes can talk to the PlayStation 3 and the Wii U over bluetooth, I was sure, it should be possible to control Plex Home Theater on my Ubuntu box too.


Request-Response oriented Websockets

The nature of websockets allows data transfer between two peers in “realtime“. This mechanism is perfect for exchanging events without relation to each other. But what if you want to ask your peer for some specific response and wait until this particular response arrives?


Bind Data to D3 using Ember.js

When I started with Ember.js lately I fell in love with its data binding quickly. Tinkering with some ideas here and there I wanted to display numerical values within a line chart. After a short research I decided to use the mighty D3 (Data Driven Documents) library for creating an SVG-based chart.


Arduino Ambilight

Insbesondere auf Instructables stolperte ich in der Vergangenheit über die eine oder andere interessante Elektronik-Bastelei welche einen Arduino als Kern verwendete.

Arduino ist ein kleiner Mikrocontroller mit diversen Ein- und Ausgabemöglichkeiten für digitale und analoge Signale. Dabei wird das Stück Hardware komplett von einer Opensource Community entwickelt.
