Windbelt electrical wind powered generator

Published on the 23rd May, 2009

A few years ago Shawn Frayne came up with an ingenious way of generating electricity on a smaller scale than wind turbines by using vibrations rather than rotary power. His invention, called the windbelt, works by oscillating a pair of magnets through a metal coil at the end of a belt which vibrates as wind passes over it. This physical phenomenon is know as aeroelastic flutter and it's the same principle that caused the Tacoma Narrows Bridge to collapse. Prototypes have generated 40 milliwatts ...

Free subversion repository hosting accounts

Published on the 17th May, 2009

I've come across a few subversion hosting services which offer free accounts so I thought I'd share the links. Most of these seem to offer a limited free account and a range of paid accounts. If you're working with subversion a lot and you come to rely on them then you may want to upgrade in the future - at least you can try them out first for free. However, if you're developing one or two projects on your own you may be happy to stick with the free account. These details are for the free accoun...

Firefox not checking spelling as you type

Published on the 16th May, 2009

Firefox has a handy feature which can check your spelling as you type in forms. To enable this go to Tools > Options > Advanced > Browsing and check 'Check spelling as I type'. If this still isn't working you may need to install your dictionary (even if your dictionary is listed under Tools > Options > Content > Languages). To do this, go to https://addons.mozilla.org/en-US/firefox/browse/type:3 and download your language, install and restart Firefox. You should now have many squiggly red lines ...

Spotify world of music

Published on the 7th March, 2009

Spotify is an online music service which allows you, much like Last.fm, to stream music to your computer via a downloadable app. You can play individual tracks or build, share and collaborate on playlists. The free version allows you to listen to unlimited music with the occasional ad. They come up about once every 4 or 5 tracks so it's not too intrusive. You can also buy a day pass for 99p which gives you an ad free service for the day or sign up for a premium account and get unlimited ad free...

Hitachi DZ-HV565E High Definition (1080p) SD Video Camera

Published on the 1st February, 2009

I've been looking through some of the little HD SD-based camcorders recently and I came across the Hitachi DZ-HV565E in Argos. However, this video camera seems to be a bit of a mystery online, there just isn't much information about it, I couldn't even find any test footage on YouTube. Anyway, I took the plunge and bought one from Argos today and so far I've been very impressed. The manual states that the camera is "exclusively available through Argos" which is probably why there isn't much i...

Outlook calendar problem - all appointments recurring forever

Published on the 27th January, 2009

I came across a strange problem with Outlook Calendar recently where every appointment which was added to the Calendar and then edited suddenly repeated forever! A scary concept! It seemed to be related to a piece of software called 'OutlookAddinSetup'. From what I've read (http://www.eggheadcafe.com/software/aspnet/29012397/re-recurring-calenda...), this seems to be something which comes installed with Dell computers. After I uninstalled this program (from Control Panel, Programs, Uninstall a p...

Flickr Picks #1: Autumnal selection

Published on the 5th October, 2008

Here's my first "Flickr picks" picture selection. Every now and then I'm going to pick some photos from Flickr with a particular theme. I thought some nice autumnal pictures would be a good place to start as it's one of my favourite seasons for taking pictures (winter being the other). The great thing about autumn is not only the colours from the leaves but also the moody weather - rain one minute, sun the next - it really creates a stunning atmosphere.
