    Can you help us a bit more? The cars you speak of are not very well described by just "those small ones". If it is too small, then circuitry and a speaker just won't fit inside.

    Tell us more about the sounds, too.

    Hello,

    If any link is dead, you can try to look in the past with "the wayback machine".
    http://www.archive.org/web/web.php

    Copy the url of the link in the search line and press "take me back"
    This will produce a page with dates the page still was available.
    Click on one of the dates and you will get the page of that date.

    Greetings,
    Bertus

    It is a Wiki, so you could fix.

    To record sound you need to use ADC and memory chips to store it digitally. Then to reproduce it you will need a DAC and an amplifier to drive the speaker.
    Describe the project better.

    Hi,

    Sure, I've been using it for many years, but it usually doesn't store PDF's etc.

    Besides that, my point was, that it is sloppy to not keep your links up to date and it makes the entire site look bad - after all, you can automate the checking procedure with programs made for the purpose, so the only real work is repairing links (or remove them).

    Russ_Hensel <- Sorry, I don't see any reason to enroll in every other guys site to do the work that they should do (have done) themselves. Certainly not a site so confusing to navigate.
    That site needs a serious make over to be useable to folks like me.
