The rubber bulb on the depth gauge is similar to what I'm using to pressure compensate BDC motors for a thruster. Glad to see I'm on the right track. I'm subscribing.
Hallo, super Idee. Wie hast du das hinten mit der Ventilkappe gemacht? Ich sehe die schwarze Kappe aber was ist das Rote an der Kappe? Versuche gerade es nachzubauen. TOP
Das ist nur ein Stück Strohhalm. Da die Druckkammer bei 10 m Tiefe ja schon zur Hälfte gefüllt wird, brauchte ich einen Überlaufschutz. Und das ist dieses angeklebte Stückchen Strohhalm. 😌
Why not just run a hose down your new tether system and keep the pressure gauge on your controller run from a makeshift aquatic version of a pitot tube?
Because that only works in theory. You’d go nuts using and maneuvering a pressure tight hose for 30 meters while keeping a soft, pressure sensitive air-chamber on your ROV that will cost you precious positive buoyancy on extreme depths. But yes… theoretically it would work of course.
Dima Naumenko thanx! Seaflo bilgepump Motors with simple brass shaft couplings and some 63 mm racer propellers with 4 mm inner threads... Check out my other videos for more information! :-)
Marco Trevisan Mota thanks! If all goes to plan we are gonna launch this baby in a lake on the weekend... that will provide some new extra footage. The video along with the construction-method-details is already under way. Can’t say when it’s finished yet though.
@@agermangineer Thnakyou! I was thinking in using a flat ethernet cable. Maybe it is more flexible and has a good buoyancy. (50meters ethernet cable); Then I will use etherenet IPV4 TCP protocol to transmit data. At least this is my idea. I hope this isn't spam, www.homebuiltrovs.com/rovforum/viewtopic.php?f=18&t=2066 ; thi is my thread where I am showing my process in building my rov and asking help. Today I got the BlueRov 3'' Dry hull!
Marco Trevisan Mota THAT IS BEAUTIFUL!!!! For data transfer (on board power supply obviously) it should be fine. Mine has speaker cables due to the resistance... but your version only calls for a rope and that’s basically it. Well done! However if my design sparks up an idea, I’d be happy of course!! Keep it up!! 👍🏻👍🏻👍🏻
@@agermangineer Speaker cables? did you switch out the CAT 6 cable on your new tether? I'm using a flat CAT 6 cable. I don't know if it's my problem or not but I have a lot of power lost. I'm in process of troubleshooting and wondering if I should have gotten a regular circular CAT 6 cable instead
Jiggle.The.Handle the question is how long is your tether? At 50‘ it shouldn’t be too bad, but if it’s longer you’ll lose a lot of power. Big time. Another possibility is your controller. Make sure to solder as many connections as possible or crimping them to have thorough power connections. In the meantime: yes I’ve switched to really really heavy 1 mm^2 all copper cables. Long story.... but now that 100’ tether has virtualy no more power loss. I’ve even added a big 1.5 Volt battery as a booster to increase the outgoing voltage to almost 14 Volts. That’s some power right there. I’m still working on the next video. I hope that I’ll have it complete soon.
a lot of epoxies are exothermic, which means they heat up while they cure. and that temperature can increase with the amount of epoxy that's curing. so it's possible that while the epoxy was curing, it got hot enough to melt your candle wax and seep through. im not an expert though, so this is just my speculation.
sound volume is not steady. But i like the ROV I want to build one my self. By my own disign. And then i want to start exploring and clean stuf up. So i need a grabing hook or something. I love nature but people always wanna destroy nature. There is a lot of rubbish under water.

Worin lag der Anlaß/die Notwendigkeit einen Druckmesser einzubauen? Kam ein Kompass als Orientierungshilfe nicht in Betracht? MfG Oliver
Neugierde! Wie tief ist das Gewässer... und ein Kompass funktioniert nicht, dafür ist das Magnetfeld der Motoren viel zu stark.

Really amazing work! Could you please describe what motors and propelers you use in your Nautilus?
Dima Naumenko thanx!

Can’t way to see the new tether. I am also making one! :)
