Forums are back!

Good day, everyone!

As you are probably aware, the forums are (finally!) back up and running.

It was a long and frustrating journey due to how the old forum database was structured, which resulted in an absolutely massive file that was exceptionally difficult to migrate to the new hosting provider. In the end, we got it figured out thanks to the relentless work of a friend who knows more about this than I will ever conceive.

Some things to note:

1.) New address! No more! The forums are now permanently hosted at Change you bookmarks! Tell everyone else to change them, too!
2.) Old bookmarks won't work! Due to the SSL settings on the old domain, your old bookmarks will get you an error message if you try to visit I'm working on setting up a new security certificate for that site so that it will redirect properly, but until then, you get the error.
3) Help me by looking around for broken stuff. If there are wonky threads, let me know and I'll see what I can do about cleaning them up. That said, bear in mind that we'll do the best we can from our end, but we need to evaluate each issue in terms of importance and may have to de-select repairs if they end up too time-consuming. (that's what you get for using a free site! ;))

Thank for your patience, everyone! I really appreciate it.

    Hi Guys

    I have just joined this forum for a bit of advice.

    Basically im a 2nd year Electrical/electronic Engineering Student in the UK so me and my fellow students have come up with an idea to build a Amphibious Autonomous Vehicle, that can be fully submerge able.

    But we are unsure what batteries,motors,drive shafts, gear boxes and any other relevant components to use.

    Ill give you a rough idea how we want it-

    Its gonna have a ballast tank on each side that will be bigger than the main body so we can add suspension and tracks under neath the ballast tanks (double hulled about 6 inch wide and 2 ft long)
    the main body will be 3 ft long and possibly 6 inch wide also this will be single hulled.
    we was thinking of using a compressor instead of a pump.

    So any help you can give will be much appreciated

    Kind Regards
