Thanks buddy, there was a LOT of great help from members here. Next setup is already in the works, I've been testing brushless motors underwater and modifying airplane props to get max efficiency. One problem was with maneuverability, then next pack will be two separate systems for redundancy...

Might as well offer some good times from my dating experiences, hope you get a chuckle or two. I went out with a girl I met at a nightclub. As a first date we drove to Fernie to go skiing, she did 160km/h the whole way there on icy roads while texting constantly. Later, she was showing pics of...

I tried plenty of fish but it seemed like everyone on there wanted to chat but never to meet. there were also a lot of entitled women on there that had no reason to be. I had no interest in online relationships so I left an addendum to my profile explaining my experience and found a girlfriend...

T-t-t-triple post! Yeah, last one. Thanks again guys!

Necro update here. Sorry for the delay, I had forgotten about this project and was just going through some old files when I found the pics/vid. I didn't completely finish the project to my usual level but it certainly worked well for saving air. I wasn't about to push the seals on the motors...

Oh I absolutely am, was just using it as an example to understand the how and why.

At depth you can hold your breath a LOT longer than on the surface, it has to do with how pressure affects the absorption of oxygen and the release of CO2. The only problem is, when you DO need air, you need it fast. Like, 5 seconds ago... So the reliable fully ON voltage is 10v and there is...

I now fully understand what "gobsmacked" means. I am in awe and wonder from the most descriptive explanation I have read in my 31 years. I pride myself on being able to explain complicated things simply but that was just beautiful. Thank you both very, very much.

I made mine with a PVC insert for golf balls. A bit of graphite spray keeps your balls from sticking (especially in hot weather, no one likes to batwing ;) ) and they will travel about 900 yards. The PVC pipe is fastened with the same anchor pin within the ABS that keeps the spud from dropping...

I bought a ring roller for bending steel, It's basically just a ($800) 70lb lump of metal. I got a call a few days later from a business owner in a town 2 hours north of mine saying he found my SIGN FOR ONLY package on the sidewalk in front of his business. Luckily it had my number on it and the...

Okay, I must be slower than I thought. The ascii circuit posted shows the vpos going through the reed switch (and a 10kohm resistor) and then connecting to the ground (through a 100kohm resistor). Am I missing how this is supposed to be wired? You can't short ground to +V or your little...

What does drain to source voltage mean? I ordered the 0.002ohm mosfets but fedex is giving me grief... You Americans don't know how good you have it when it comes to your postal service.

The 60v rated fet looks too good to be true, damn that's a huge max current... There won't be any "chassis" to mount it to, it will just be floating around in a backpack, likely mounted in a 3D printed box that water can flow through just for durability sake. With that little heat though it...

Damn you guys are good. Well I'll order them before I head out camping. >160A lol, THAT is plenty of overhead... I'll waterproof the whole works but leave the heatsink exposed to the surrounding water, should be able to dump a fair amount of heat lol

Would it be able to handle >30A? I don't mind paralelling a few of 'em ;) The one I listed will do 42A constant or 60A max but I think I read somewhere that it needs a Vmin of 80V.
