Everyone’s heard of the iTrip, wirelessly broadcasting music from your iPod to your car stereo. And that at the moment they are completely illegal in this country.

We decided to try a slightly different method of using music wirelessly on the road. Multiple cars, one soundtrack. The theory is simple, give each car a cassette adaptor and an Apple Airport Express, then in one car have someone sitting with an iBook playing music using iTunes to the Airport Express.

It’s also possible (and very easy) to share IM messages (using iChat) between the cars or even files messages, but I dont know why you’d want to. Actually, I can’t see any practical reason for having the same music playing in both cars at once either - but it seemed like a fun idea at the time. (Both cars also had a high-speed broadband internet connection - but the only person using it was Andrew - and anyone else that could log into our Open AP in the few seconds we passed within range of their house for)

Anyway, we managed the journey from Edinburgh - Glasgow without the signal between the two vehicles dropping out once, allowing Martin in his car to listen to the wonderful (?) playlist (and impromptu radio-style announcements) by the other car’s resident DJ, Andrew (It should be stressed at this point that he wasn’t driving)

One thing it does prove is that wireless networks are quite capable of working at speeds of 60-80mph.

On another note, I imagine anyone with wireless scanning software running at home at the time probably got slightly confused as to why car registration numbers were showing up in the scan
