1. Introduction: A little while ago my smoke detector started to randomly wake me up with unexplainable alerts so I decided that it’s time for a new one. The hunt for a model that would be available in the UK for under £50, without the need for a third party cloud and the ability to […]

Introduction: For those unaware of the event, CeBIT is held annually on the Hanover fairground. For an idea of scale, the exhibition area roughly covers 450.000m2 and the five day event attracted over 300.000 visitors this year. For those of you who know the IP EXPO in London, imagine 15+ halls like it and multiply

Introduction: I was lately blessed with an array of coursework assignments for a module called “Paradigms of Programming”. The language I picked to get into imperative programming was Pascal and I had a few fun weekend with it programming a currency converter. I’m hoping others might find the resulting code helpful or interesting 🙂 Preparations:

Introduction: I was lately blessed with an array of coursework assignments for a module called “Paradigms of Programming”. The language I picked to get into functional programming was Haskell and I had a few fun afternoons with it programming a word counter which counts both the total number of words as well as the frequency

1. Introduction: Since I’ve just upgraded the NAS I’ve ended up with a spare Mini-ITX Atom board. Perfect timing to replace the old Smoothwall gateway and finally eradicate the last 32bit machine I’ve got running 🙂 I’ve been using Smoothwall since 2007 now, my first box was based on a P3 1Ghz but quickly replaced

Here was me thinking that it would be a good idea to finally replace my old laptop based Smoothwall setup with a nice mini-itx one… The mini-itx board in question is a Intel D945GCLF2 and has been working hard over the past few years as my home NAS. Since I just swapped it for a Gigabyte GA-D525TUD to

Introduction: OS X Mountain Lion just popped up in the App Store so I could not resist to download it at work where it takes 30 minutes compared to several hours back home. As with Lion the setup is handled through an installer which one get’s (after appropriate payment obviously) through the App Store. The

1. Introduction: For my new Arduino controlled greenhouse project I lately required a new Arduino Mega Protoshield. I’ve had the nice red Sparkfun one for quite some time now but since I’m using an Arduino Mega 2560 for this project I wanted something that brought up the additional new pins and the ICSP header. The

Introduction: This is the first of a series of posts to describe my second Arduino automated greenhouse. It’s simply too big a project to cover everything in one post so I’ve decided to split it into a few smaller posts. In this first part I’m going to quickly describe my water, power and network setup.

Introduction: 3D printers have taken off over the last couple of years and especially the last half year with more and more models pushing onto the market and competing in particular for the lower budget end of the scale. High quality 3D printing, dual colour printing and sizes beyond 10cm are still reserved for the
