I store all of my media on a file server (running Ubuntu Server 10.04) which currently contains a 6TB RAID5 array, then stream whatever I want to watch to a client device hooked up to my TV, up until yesterday this was a Popcorn Hour A-110. Although the A-110 plays back almost anything I throw at it, and generally flawlessly, the navigation is not the best, the UI is not the prettiest to look at and the network functionality is pretty slow. I’ve had my eye on Boxee for a while now and have been patiently waiting for the release of the Boxee Box, but they’ve recently announced on their blog that it has been delayed until November 2010 for the US release, and no mention of the Europe release. With this in mind, I decided to run Boxee on a low powered HTPC.

A couple of people in both forums and IRC have recommended the Acer Aspire Revo 3610 net-top machine as a candidate for running Boxee, so after a little research I picked on up from eBuyer at a bargain £180 for the N330 / 2GB / 250GB / Linpus configuration, delivered the next day for free. After firing it up for the first time, I spent less than 5 minutes poking around the pre-installed Linpus out of curiosity (the 250GB disk was oddly configured with a single 10GB partition), then promptly wiped it and installed Ubuntu 10.04 (x64) and the latest Boxee release.

Having previously read Liam Green-Hughes’ website, I was aware that I needed to tweak some settings to get the digital sound working, though there was a slight difference with my Revo in that I have three different S/PDIF levels within alsamixer – “S/PDIF”, “S/PDIF Default PCM” and “S/PDIF 1″. I un-muted all  of them but have yet to experiment to see what each of them does. I set my output device to “Digital Stereo (IEC958) Output” within the Ubuntu sound configuration as I want the audio to be sent to my amp over S/PDIF for decoding; after messing around with a few different combinations of settings within Boxee I was getting sound for files encoded with normal stereo sound, but silence for anything with multiple channels (DD / DTS). After a couple of hours of tinkering and research, it turns out that pulseaudio has a default sample rate of 44.1kHz and AC3 (Dolby Digital) is signed 16-bit little-endian 2-channel 48kHz PCM data, configuring pulseaudio to run with a sample rate of 48kHz appears to have fixed the issue, as I am now getting DD and DTS passed to my amp for every media file I have tested.

After playing around with the Revo / Boxee combination for about a day, it’s generally all positive; it plays back 720p/1080p content perfectly by passing the majority of the HD video decoding to the ION chip with the help of VDPAU available within GNU/Linux, the CPU is running at ~10% during all of this while managing perfectly with non-HD content too but with a little more strain on the N330. While “idling” on the Boxee home screen, one of the CPU’s threads is curiously always running at 100% load, though it is possible it is still indexing all of my media with it reporting “identifying” next to one of my sources. It has currently successfully identified 99% of my media requiring me to manually identify a handful of files, but this is perfectly acceptable considering the brilliant interface complete with covers and descriptions for all of my movies and TV shows. There is a slightly annoying wait when switching between the different areas of Boxee and sometimes a slight bit of lag when browsing through the media, but this could be down to it still indexing the content.

There appears to be plenty more to play with such as web content and applications, from what I have looked at, Flash video plays back fine in standard definition but HD Flash content is completely unwatchable – This is likely down to the lack of 64bit Linux support from Adobe. Other web based content such as the video made available within the Revision 3 application plays back perfectly, I’m pretty sure it’s HD too, but I couldn’t find an option to switch between the different encodings of their content.

One of our office printers decided to die the other day, a Brother multi-function laser printer, which I recall took quite a lot of messing around to get it printing from Ubuntu and once it was set-up it always took a while to send pages to the printer. Sometimes, it printed just a bunch of garbage instead of the document I sent too.

Our new printer, an HP 2727nf MFP, was a completely different experience. After hooking it up to the network and selecting to add a new printer within Ubuntu, it searched for printers, found the new HP, fetched and installed the required drivers and just worked! Pages are sent to the printer almost immediatly and have printed perfectly every time, so far.

Also, I set the same printer up on 6 machines in the office, 1 x Ubuntu, 2 x Xubuntu, 1 x OS X, 1 x Vista, 1 x XP Pro. By the time it was set-up on the first Windows machine I had already completed the set-up on all three Linux machines – Two thumbs up for Ubuntu and HP.

Although I hardly use my SD-1, due to my GT-8 having all of the overdrive settings I could possibly want, it was still annoying me that I had a faulty pedal sitting on my shelf. The problem I was experiencing was that the SD-1 was constantly stuck in its on position – Stomping on it did nothing but continue with the overdrive.

After taking it apart and hooking it back up to some power, a guitar and an amp, in its disassembled state it was working fine – Reassemble and the fault reappears. It was instantly obvious that something was shorting out against the metal casing. You’d have thought that there was some form of non-conductive coating on the base-plate – Maybe there is, but defective near the switching area of the circuit. Covering the base-plate with insulation tape fixed the issue and it’s now working perfectly again!

My media server was getting to the stage where it required some extra discs, so I purchased another pair of 500GB SATA disks and a SiI-3114 based PCI to 4-port SATA controller card to hook them up to as I was out of spare SATA ports.

Upon booting there was no sign of the cards BIOS during POST and no sign of the disks attached to it either after booting into Ubuntu, though running lspci reported that the card was present. After poking around with a mixture of Google and the Ubuntu forums, a number of people were having issues with the card but no conclusive fix had been found.

So I head on over to the Silicon Image website to check if there are any new BIOS images available, and surprisingly there was! After downloading, and realising that the only flash tool available was DOS based along with my server not having a floppy drive or a CD drive to boot into a DOS shell with I managed to get a USB stick booting into DOS with the flash tool.

To cut the story short – Flashing the card with the latest non-RAID version of the BIOS fixed my issue. It was now displaying the BIOS upon boot, and the attached disks were visible when running lshw -C disk.

So I accidentally spilled a cup of tea over my Blackberry. Fortunately, after drying it off most of it worked perfectly bar one of the most important components in a mobile phone – The microphone.

After doing a little research, it turns out that the mic is surface mounted to the keyboard PCB so to replace the mic I’d need a new (or working) keyboard PCB. The only place I could find this component new was on some American website, which after shipping and other taxes involved in importing stuff, would have cost about £70. Or, I could have sent it off to Vodafone for repair at a cost of £60 and a few weeks Blackberry-less no doubt.

I ended up grabbing what was described as a faulty 8800 from someone on eBay for about £40, the description said it had a software fault, so there was a good chance that the hardware was in good condition. It turns out that there was nothing wrong with it from what I could gather after messing around with it for a couple of minutes. But it was on the o2 network, so no use to me. (more…)

Since I first bought my Logitech MX5000 combo it has never worked correctly on Ubuntu (back to 6.06 maybe…) after booting. The keyboard would work perfectly in the BIOS and even in GRUB, but as soon as I reached the (GUI) log-in screen my MX5000 would become unresponsive until I disconnected the USB Bluetooth receiver and plugged it back in. As you could imagine, quite tedious on every boot.

After doing a bit of research, this appears to be a fairly common issue. One suggestion that did work for me was to remove the bluez-* packages, but apparently there is the side effect of other Bluetooth devices no longer working. This isn’t an issue for me, so it’ll keep me happy until a real fix is in place.

Drop the following into your CLI if you’re having the same issue…
sudo apt-get remove bluez-cups bluez-pcmcia-support bluez-pin bluez-utils

I’ve had my MPC 500 for a couple of weeks and in my limited experience using it, I appear to be having an issue. I’m not sure if it’s a setting that needs changing, if the 500 is faulty, my limited RAM (I have 128MB on order) or if it’s purely a limitation of the 500 model.

In a nutshell, I have created a sequence and have it looping while I play with some samples over the top. When playing patterns over the top, it appears to be affecting the playback of other samples in the sequence. (more…)

Dension, the guys that released the Gateway 500 interface that allows one to listen to their iPod (or other source) through the OEM head unit have now brought out an accessory, that when hooked up inline between the iPod and Gateway 500 gives Bluetooth functionality. The BTA1000 supports both A2DP/AVRCP and HSP profiles which are generally used for hands-free calling and streaming audio from media players or navigation devices. I got my hands on one, so on to the install… (more…)

I was looking at adding some extra functionality to a couple of bits in my guitar set-up, in my case this involved buying some footswitches – One for my Vox AD30VT amplifier, and one for my Boss RC-2 Loop Station. Vox offer the VFS-2 and Boss has the FS-6 for a combined cost of around £60, which is quite a bit for what they actually are. Okay, the Boss has a few fancy features like interchangeable latching / momentary functionality, status LEDs and switchable polarity but I don’t need any of that. I was sure I could build something that does exactly what I needed for a lot less than sixty quid, so I did. (more…)

After looking at my usage logs, I have noticed quite a number of people have found this website after searching Google for the Gateway 500 firmware. So to help you all out, here are all of the versions released so far:

GW5_MOST_100.ZIP
GW5_MOST_104.ZIP
GW5_MOST_105.ZIP
GW5_MOST_202.ZIP
GW5_MOST_203.ZIP
GW5_MOST_205.ZIP

The above firmwares are for the MOST based version of the Gateway 500, i.e. Porsche, not the D2B version that is used in Mercedes cars. Installation is as follows:

Extract the G5_B_UPD.ROM file from the update package and copy to the root of an USB flash drive, then connect the USB drive to the Gateway 500 while it is powered. If there is an iPod connected to the Gateway you can leave as it is in any playback mode or status, do not need to disconnect or stop playback.

Update procedure will start automatically within few seconds and takes cca. 1.5 minute. Do not disconnect the USB drive within this time.
After a successful update G5_B_UPD.ROM is deleted from the USB drive and GW.EES.BIN file will appear with the new software version. If an iPod is connected during the update the iPod screen will light for the second time when the upgrade is completed and the new firmware version appears on the right upper corner of the screen.

When finished, it is better to restart the Head Unit and the Gateway 500.
