iTrip FM transceiver for 4th gen iPod review

September 14, 2004

The Griffin Technology iTrip for iPod is a very good gadget if you want to listen to your iPod via a car stereo or a friends sound system.

Older car stereos that take cassettes can use cassette adapters with good results but many newer car stereos only have CD slots and no auxiliary input. The iTrip sends the music on a custom FM radio channel and may be your only option in that case.

All you have to do is to tune in to this channel and you have a wireless connection. There are slight differences between the FM band used in USA, Europe and Japan but the iTrip supports all three formats.

Since the iTrip gets it's power from the iPod (see the little connector next to the micro jack) there is no need for extra batteries. iTrip turns it self on when you start streaming music and turns it self of after 30 second of silence.

The design of the iTrip is very good. It fits like a glove on the iPod and looks like it should have been there by default.

To tune your iTrip to different channels you play short sound files that command iTrip to use a different frequency. The installation CD comes with UK channels from ~88-108MHz in 0.1MHz steps.

The iTrip costs around £30..

    something is wrong with your comment links:

    The requested resource
    is no longer available on this server and there is no forwarding address. Please remove all references to this resource.

    btw, do you use mt-bayesian any longer. and what are your experiences?

    Thank you for pointing it out!

    The problem was that I was trying to limit a RewriteCond with the standard <LIMIT> directive. This only works for the mod_access commands and not for the mod_rewrite.

    The correct way of doing it is to add a RewriteCond %{REQUEST_METHOD} instead.

    Regarding the mt-bayesian, it has captured ALL spam comments thus saving my main page from embarrassing porn spam.

    Unfortunately, it has quite a high false positive rate so I have to check for new comments often and release the good ones.

    thanks for your explanation. i have seen your comment entry im my weblog and gave you an answer. i set up my email adress today, but it does not work until now. perhaps it takes some time. as you may have seen there is some kind of spam in my relatively new weblog - referrer spam. and it will be only a question of time until the first comment spammer arrives. thus it would be interesting to find a good anti-spam solution. and perhaps a good weblog software that has anti-spam functionality build in by default :)

    I have had to apply a combination of blog software (mt-bayesian) and Apache tweaks. See below for some options to fight spam comments.

    Study your access log and try to find a pattern spammers are using. If you find one, edit your .htaccess to ban them commenting.

    Almost all comment spam comes from open proxies. Check for open proxies (checkdnsrr() in php) before you allow a comment post.

    Most comment spam is submitted by bots. Implement a decent CAPTCHA (http://dbvt.com/blog/archive/2004/10/29/441.aspx).

    Connect your blog to a centralised IP black list. mt-blacklist does this for MT.

    how does this work? are you sure you can recognize proxies this way.

    i have seen another interesting experiment that used cookies to differentiate between users and robots. not bad, but there had been trouble with some browsers.
