Hyperion is an open source ambient light implementation controlled primarily by an Raspberry Pi. The main features of Hyperion are: 1. Low CPU load. For a led string of 50 leds the CPU usage will typically be below 2% on a non-overclocked Pi. 2. Json interface which allows easy integration into scripts. 3. A command line utility allows easy testing and configuration of the color transforms (Transformation settings are not preserved over a restart at the moment...). 4. Priority channels are not coupled to a specific led data provider which means that a provider can post led data and leave without the need to maintain a connection to Hyperion. ...

DBLX 3.3 is available! DBLX is a multi-user, client-server relational database. DBLX uses standard SQL and has many types of clients, and client API's. DBLX has a REST server to allow direct access from web applications. The design goals of DBLX are to produce a very fast database which can be used with standard ANSI sql. DBLX source code is available in C# and Java. DBLX includes the server component, a command-line client, as well as client APIs. DBLX is well-documented so that...

Researches have shown that immediate feedback can increase energy saving dramatically. YoMo aims to empower people using low-cost open hardware smart meters in their household. The metering system consists of a coordination unit, a raspberry pi, and several smart meters, arduino boards equipped with communication shields and our self-designed yomo metering shield. The smart meters are attached to household devices and monitor their energy consumption. The gathered data is timestamped and...
