I hate to be rude for the sake of it, but I have this kind of need to 'service' this thread (for want of a better expression) seems I posted it up here, people ask questions and I share any information I have, mainly so that if they are interested they can knock one of these things up themselves (or their own version).

But c'mon, you have got to meet me half way !

In answer to your question: "so it lights up when you attach a battery?" - an answer:

No, it does not light up when you attach a battery, it is powered by a spell cast many thousands of years ago on a planet called 'Xzious' by an evil warlock know to the people who live there as 'Mordecious'. The prominent battery pack sat on the saddle in all the images, which is attached to a power lead, along with the red operation LED are all just illusions projected into your mind by the spell cast by Mordecious.

Don't be fooled, liverunbike seems to be one of the few posters here to see through the spell and question how this thing is powered, I say well done liverunbike.

;P
