A while back I picked up an ECS 945GCD-M motherboard to replace my dead VIA board that was running my RAID server. The board is pretty nice, sitting there completely silent, running 64-bit Ubuntu and packing far more power than the board it was replacing. But it has one glaring problem; the network card on the thing didn’t work out of the box in Linux. I had been running a cheap USB network card I had laying around, but it was slow and I hated that I couldn’t get it working. So, I set out to make the onboard Atheros AR8131M chipset work.

Google will give you a plethora of guides for compiling the drivers (this one is probably the best), but I just couldn’t get things to load. It was also never clear what version of the drivers I should be trying to run. Most tutorials made reference to 1.0.0.9, some to 1.0.0.10, but the current version (at the time of this writing) is 1.0.1.9. In the end, though, that’s the version I did manage to get working. Here’s how I did it:

I recently send my Samsung X360 laptop to the shop. The bearing on the fan had gone bad so I sent it in for warranty replacement. Before I sent it, I thought I would wipe out all my data since a lot of it was work-related and I didn’t need that information getting out, plus I didn’t want to confuse the poor tech with Linux.

When I got it back, I immediately installed Ubuntu’s most current version, 9.10 (Karmic Koala). I was really impressed with it; even more-so than with 9.04 in fact. But I ran in to a problem when I was setting it all up; I couldn’t get the backlight adjustment to work.

Telecommuting is a pretty sweet gig with a good number of benefits. To name a few, while I’m working I can:

• Toss some laundry in the machine
• Start my lunch and work while it cooks
• Sign for packages when they are delivered

And that’s just the tip of the iceberg. However, to make telecommuting possible, there are some technologies I simply MST have working. VPN is a big one, so I can get at the computers back in the office. SSH and FTP access is important to manage servers and files. And of course, I need to communicate with people; for that, we use AIM and Skype. Up until recently, it’s been enough for me to use my Nokia N800 to make my calls back to the office. It’s no good for chatting with video though, so I needed to set it up on my desktop with my camera and, preferably, my headset.

Simple enough task really; both my Logitech webcam and Plantronics headset work out of the box with Ubuntu (at least in 9.04) with nearly zero configuration required. I just plug them in, tweak Skype quickly and I’m up and running. However, with the addition of PulseAudio in the more recent version of Ubuntu, this became a little trickier.

I’ve been considering picking up a new laptop for a while now. My old laptop, an ageing Dell Inspiron 8500, had treated me well for a few years, but I really wanted to change to a more portable machine. The Dell weighed in at around 8 lbs., had a battery that lasted about half an hour at its best and ran almost too hot to touch at times.

Ultimately, I just wanted a machine that was light, had a long-lasting battery and had a full-size keyboard. The 10-inch netbooks looked like a good buy, but it was difficult to find one that was worth buying. I had been considering the Lenovo S10, and came close to picking one up about a month ago when I found one for just under $300. What stopped me was reading about overheating problems with the machine. I’ve wanted the MSI Wind since it was announced, but it was always over the $400 mark, which I don’t think is a reasonable price for that class of machine. All of the other offerings were either overpriced, lacked some key features or had batteries that just weren’t going to cut it. In most cases, all of these were true.

I have a server set up with a RAID-5 array that I use to back up pretty much all of the data I have. Sure I have a bunch of things burned to DVD, but at only 4.3GB a pop, that can very quickly add up to a number of DVDs, and in fact already has. My server is actually an upgraded version of my old machine, running 4 500GB drives in a RAID-5 configuration. Since I’m cheap and don’t care all too much about performance, I use software RAID in Debian with mdadm running the show.

A short while ago, I had a drive that started clicking every time I would transfer large amounts of data to of from the box. Since all of the drives are mounted on the same bracket, it was nearly impossible to tell which drive was actually doing the clicking. I had a spare that I picked up a while back, so I figured I would wait for the drive to fail and then simply replace it. The problem was, when the drive finally did fail, another drive also failed with it, and if you know anything about RAID-5, you know it can only handle 1 drive failing at a time. Things were looking bad.

I’ve seen all kinds of really cool projects that use the fancy new Arduino microcontroller. I’m not the biggest fan of C or C++ (to be honest, I hate them both), but the Wiring model and the Processing environment seems interesting. So much so that I decided over this long weekend that I wanted to get in on the fun on purchased a kit from Adafruit. Sure I could have gotten it cheaper and ditched all the extras, but it seemed reasonable given that it comes with the Protoshield, breadboard, a couple power options, USB cable and some extra goodies to get me started out of the box. I figured it was all worth it.

I have some ideas for the normal automated plant watering, temperature-based fan controls and email and chat LED alerts, but I don’t have any revolutionary plans for the device. Talking to Jason, he gave me the idea of controlling motors with the unit which got me thinking back to the Assembly-based cars we coded for in college. I can see putting together a little car that can sense and route around obstacles and he suggested mounting some IR transmitters to turn TVs in the area on and off at random, which would be pretty fun too. I caught this “Large scale DOT Matric printer” on Hackaday too, which made me think about feeding images into the device and having it drive motors to actually create them on a large scale either like a DOT Matrix printer or a planer.

Anyway, we’ll see how much I do with this thing and how far I get. If nothing else, it’s an excuse to get back into hardware hacking. And if things go well, I can actually start posting projects up here. If you have any ideas for cool things to try out or questions about the unit, please post in the comments.
