Raspberry Pi network audio player: pulseaudio, DLNA and bluetooth A2DP – part 2: DLNA


Raspberry Pi DLNAThis article is part 2 of 3, where I cover DLNA renderer and DLNA media server. At first I planned to do only the rendering, but now also included serving media for those who have hooked up some storage with music/videos/photos . Parts 1 and 3 focus on setting up pulseaudio over network, and a bluetooth audio A2DP accessory role for the Pi respectively. In the end you get a multi-protocol audio-playing Raspberry Pi.

Raspberry Pi overview – 3.5 Watt Linux board


Raspberry Pi

Raspberry Pi is advertised as an ultra-inexpensive (~35 USD for model B) mini computer running Linux. That’s why I just had to give it a try 🙂 It is especially interesting because it opens up a lot of possibilities combining Linux + small footprint + low memory consumption + connectivity + reasonable price. This article refers to model B of the board.

Windows 7 domU on XEN 4 HVM with Debian Squeeze dom0


XEN logoA couple of not-so-obvious-at-first hints if one day you need to get Windows 7 Professional running as domU on XEN 4 HVM virtualization where your dom0 is Linux Debian Squeeze. And with the assumption that it is to be bridged with eth0/peth0. Continue reading ‘Windows 7 domU on XEN 4 HVM with Debian Squeeze dom0’

APC Smart 1000 (SUA1000I) with NUT / Linux

Just before you’ll call me an UPS maniac – here’s one more review. My current choice for 1-3 box server setup – APC Smart-UPS 1000VA USB & Serial 230V is not really similar to the SC1000 reviewed by me earlier, as the latter has a somewhat simplified design internally and also the box itself is different (standalone/desktop vs standalone/RM). And the non-SC is a full-sine model, and has a richer LED display. Continue reading ‘APC Smart 1000 (SUA1000I) with NUT / Linux’

Windows XP on Android


Windows XP on Samsung Galaxy S2 - bootingRecently I have been playing around to get Windows XP to run on my Android ARM phone. After a decent amount of research and work done (found out later that most of it was unnecessary) I managed to get proof of concept Windows XP to boot with usable resolution, network, and no sound 😉 Like my colleague said: Just because I can 😉 Continue reading ‘Windows XP on Android’

Huawei E1552 Modem with Debian Linux


Let’s assume that you need to install a multi-purpose firewall/server for your customer, but their ISP of choice is just too lazy to install their cabling to customer’s premises. Let’s also add that all you are left with is a Huawei E1552 Modem for HSPA/3G mobile packet data with a data plan SIM card. If so – here’s how I put it to use for persistent Internet uplink (this time with Debian squeeze) until the semi-decent ISP is ready. Continue reading ‘Huawei E1552 Modem with Debian Linux’

Hi! Here’s another UPS review 😉 I am not an UPS tester by profession, but this topic seems to be around me recently, caused by various opportunities. This time I am playing with APC Smart SC1000 tower/rack-mount unit, and it’s nut interoperation. Continue reading ‘UPS APC Smart SC1000 with NUT / Linux’

UPS Ever Duo II Pro with NUT / Linux – bad idea


A bugIn my previous post about that device I described UPS Ever Duo II Pro working with nut under Linux, along with variables it exports, battery charge and drain cycles and this UPS’ issues. This follow-up is why using this UPS for serious unattended production environment is not a good idea. Continue reading ‘UPS Ever Duo II Pro with NUT / Linux – bad idea’
