<div dir="ltr">Actually a good friend of mine is a PhD who works for the Navy as a civilian and was commissioned some years ago to write a white paper on the threat of PSUBS (the boats, not the organization). He is not the slightest bit a paranoid person, on the contrary I respect him highly. Of course I have not actually seen his paper nor would he be able to tell me what is in it, but knowing him and also seeing we have not been regulated out of existence chances are it came to common sense conclusions. However, having public discussions about how to create an home built torpedo strikes me as just asking for trouble. Remember the guy who crashed his drone onto the White House lawn a couple of years ago<span style="font-size:12.8px"><font color="#000000">? He was not a terrorist either, but I think other drone enthusiasts would be quite justified in thinking it was not a productive thing to do. Anyway, enough said... I hope not to get into a philosophical argument as I think we would agree it could go on for a hundred years. </font></span></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Sep 12, 2016 at 7:45 PM, Marc de Piolenc via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">If you regulate your activities based on what a paranoid government agent might perceive about them, you have surrendered your freedom without a fight.<br>

Hi Lasse,<br>
<br>
You're very well regarded here, we all know you and have for a long<br>
time. But may I suggest that in today's world someone who did not know<br>
you and came across such a project (for instance a Youtube video of it)<br>
might not react the same way? There are people whose full time job is<br>
spotting security threats, and what is really a completely innocent<br>
initiative might cause them concern. They can be expected to err on the<br>
side of caution with regulations or prohibitions of some sort. In short,<br>
I would suggest for the sake of everyone, this idea although fun is<br>
probably not advisable given the current state of affairs. It pains me<br>
to say so, because I used to build canons and bombs for fun when I was a<br>
12 year old, but times have changed.<br>
<br>
<br>
Cheers,<br>
<br>
Alec<br>

Hey guys,<br>
<br>
My crew friends at submarine Malen are planning to build a<br>
torpedo-ish machine to fool around with in the evenings.<br>
We are thinking of taking a scuba-tank, connecting a simple motor<br>
from an air drill and connecting a propeller to it. We are planning<br>
to use RC for steering and heading hold via a gyro.<br>
Have anyone tried and have input on this?<br>
<br>
Cheers, Lasse<br>
