Raspberry Pi

I’ve got a Raspberry Pi since a while back. I placed an order the morning┬áthe Pi was released. However, I also have a newborn and a four years old, so progress on the Pi has been slow. Now, finally, I have a setup that I’m pleased with.

I use my Nokia N900 charger, a non-name powered USB HUB, and a d-link DWA-131 wifi USB dongle. This page is a great resource for selecting periphials. The only draw-back right now is that the HUB and Pi draw power using separate supplies. Sharing a single 5V feed would reduce the need to free wall sockets from two to one :-)

For casing, I use a self-printed Raspberry Pi case with GPIO-access. However, I’ve not had time to fiddle around with the GPIOs just yet. The case fits nicely onto my noname USB HUB, so I’ve joined the two using a piece of velcro. The look is not very stylish, but the packaging is nice.

For software, I use the Raspbian image featuring debian built for armv6 with hard-float. I also use the qt50-snapshot from here (look under nightlies). That image is missing qmlscene and qmake, so for development, I guess I have to setup a cross compiler, or spend 4-5 days compilation time building a Qt 5 snapshot on the Pi myself. Not having qmake is sort of ok – compilation times are bound to be long, but qmlscene would had been nice, to be able to do local QML development.

I’ve had Qt 5 working from a snapshot for Debian wheezy with softfloat which had qmlscene pre-built. The framerate is nice, so it felt as if there was true potential there. I’m looking forward to being able to build my own little C++ QML extension and try it out for real.

Pics, code and more info will follow.

The Digital Project

I’ve decided to bread life into an old domain, but let me tell the story from the very┬ábeginning. Way back, when leaving university, a couple of friends of mine and myself went looking for a place to keep our projects, personal homepages (yes, we geeks had those back then – sort of a facebook profile, but without the centralization and games). The end result was that we bought the domain digitalfanatics.org and some hosting.

The years passed. From my side, I ran The Independent Qt Tutorial there. Got a job, wrote a book, got a Qt job, etc. For the others, life also progressed. In the end, the result was a site with a broken wiki installation and outdated contents. So, I decided to take over the domain and do something about it.

During the time that passed, I became a software guy. There is no point trying to resist that any more. I did study electrical engineering – microprocessor architecture, digital construction, etc – but I ended up a software guy. Now, I happen to have an urge to explore and write about things. This turned into a plan – Digital Fanatics would be a place where I could write about electronics and cool projects.

The site has been running for about a month now, without any promotion apart from myself twittering now and then. Still, the average reader count has increased to 50+, and the peak day had more than 100 unique visitors. This is far better than I expected and a real inspiration to me.

So, for those interested in smaller system, preferably open source, and such, feel free to visit the new digitalfanatics.org. And, yes, it will still host The Independent Qt Tutorial. It draws an amazing amount of traffic (1000+ daily hits) despite being Qt 3 – I really should find the time to update it for Qt 5 :-)
