More adventures with Minecraft

Following yesterday’s bumpy start, I was determined to make some progress with Minecraft today. I had hunted round our storage and gathered the following: A Dell Vostro 200 desktop with 1GB RAM which my wife used before she got her laptop. We stopped using this because its hard drive broke and it refused to boot …

Installing minecraft on the Raspberry Pi

There has been a lot of excitement around the blogosphere following the announcement of a free version of the wildly popular game Minecraft for the Raspberry Pi. My teenagers and their friends are somewhat obsessed with the game, so the chance of drumming up a bit of interest in software and hardware development by joining …

Has anyone got a bluetooth keyboard working with Raspbian “wheezy”?

I have just spent an annoying evening trying to get my little bluetooth keyboard working. Without success. Plenty of websites seem to offer instructions, but so far none of them have worked. I’m pretty sure the bluetooth adapter is compatible. It certainly gets as far as showing the ids of my keyboard and a nearby …

Automatic Raspberry Pi board revision detection: model A, B1 and B2

When the raspberry Pi model A was announced a few days ago, I ordered one straight away. With three different models of raspberry Pi now available (or four, if you count the red Chinese variant), working out the capabilities of the board is becoming increasingly important. It’s vital for anyone involved in making hardware or …

Raspberry Pi USB WiFi working at last

A few days ago I got a bit cross with myself while trying unsuccessfully to get a wi-fi network connection working with Raspbian Wheezy. I guess I must have rushed into it, because I obviously didn’t look in the right places. However, in my defence it seems that sometimes changes to the configuration don’t always …

Why is it so hard to build Raspberry Pi Linux drivers?

A few days ago I complained a bit about the profusion and confusion around the Linux drivers for the PiBorg LEDBorg multi-colour LED. With a bit of renewed energy, I thought I’d have a go at improving the situation by including a test for board revisionin the driver and ensuring that the correct GPIO pins …

Controlling Raspberry Pi GPIO from Ruby

After my grumpiness yesterday, I thought I’d better strike out in a different direction while I consider my options with the various sub-projects I have on the go at the moment. I have mentioned before that I am a member of local Ruby user group “IPRUG”. This is on my mind at the moment as …

Fitting a Real Time Clock to Raspberry Pi

The Raspberry Pi is a great little board, and it still amazes me the huge range of things you can do with it. However, it’s not without its limitations. One of these limitations is that it has no “real-time” clock. Sure, it has internal counters and the like, and when running under Linux it will …

Ruby and Sinatra on the Raspberry Pi

I am interested in all sorts of software development and related areas. In particular I do a lot of Java and Ruby development, both for my day job and for fun. Once a month I try to get along to IPRUG, our local Ruby user group and meet up with other Ruby software folks for …
