[@ludwigvanzappa9548]

I worked with one ROV when I was a professionnal diver. The ROV was slightly positive and a motor on top would make it go down or boyant (or neutral). If the ROV failed and was out of electricity ,it would come up to the surface because of its positive boyancy. It worked very well .

Hey Sam, good to see you again. Miss your videos of this and that.

[@JR-kk6ce]

I made a similar ROV about 5 years ago using regular RC airplane parts. You can use a flight controller for stabilized autonomous operation, SBUS, etc. I used a modified scuba regulator, one of those small spare air tanks, and a pressure relief valve to make an automatic pressurization system which enabled the ROV to go 329 feet deep without any problems. The possibilities are endless. The one drawback is that you will need a thin antenna wire attached to the ROV with a small surface float and antenna so that it can use GPS for autonomous navigation, video, and PWM/SBUS signals. What is really cool is that one can send regular radio signals for a short distance underwater, allowing you to use a camera without penetrating the hull of the ROV with the camera wire. This only works for a very short distance. If you want longer distances, you have to use low frequencies which will immediately draw the attention of Federal authorities which strictly control such frequencies for military submarines. You can fly underwater with an ROV just as you can fly in the air with a quad or plane. In fact, it is actually better because there are few if any restrictions so far. But, I have to caution everyone that the government is aware of just how dangerous such technology can be in the wrong hands.

[@leonhelen]

Hello

[@lukekamrath8795]

Hey Peter, I noticed some flickering in the video feed when you were toggling the controller switches. That is probably due to the way you wired the signals to the relays. The ethernet cable has 4 differential pairs. Because the video ground isn't isolated there is crosstalk that will increase with the cable length when ever the switch state changes. This is due to an induced magnetic field along the wire from the current to switch the relay. There will be a voltage spike in nearby wires. If the wire gets long enough the voltage spike may damage the video camera or display circuit. A better circuit that would take advantage of the differential pairs and isolate the video lines is possible. It is still analogue and cheap. You need double pole double throw switches and four diodes per relay. Each switch uses a coupled wire pair in the ethernet cable, leaving one pair for the video. If you are interested I can figure out how to send you a schematic.

[@beautifulsmall]

Motor options , its a base 3 number, 3x3x3 ,27 so in binary + or - it can be achived with 5 bits . I could see there was a solution but havent formulated the diode logic, is there a 5 bit solution I wonder with diodes and switches. No rely allowed.

[@fookingsog]

Learn how/why UTP was designed. Each color pair has a different twist ratio to other pairs. Twist puts noise 180° out of phase thus nulling/negating said "noise"... *exactly* why UTP was designed!!! That being said, if the system is designed correctly, the control cable will *only* be low voltage controlling the relays within the sub. It appears that the video *flicker/jitter* is "back emf" when motor direction is switched. This most likely can be remedied with a variety of simple ferrite chokes and capacitors across the terminals of the motor to eliminate the voltage interference.

[@lukekamrath8795]

@@beautifulsmall Each relay needs three states, off, forward, reverse. The relays have three pins, a common ground, and a pin to energize each state. The trick is in the DPDT switches which can be wired directly to a battery in such a way that they send three states on two wires, off, powered, and inverted powered. (a) +vss ------ [ ] [ ] ------ (d) - gnd (b) s left ----- [ ] [ ] ------ (e) s right (c) - gnd ----- [ ] [ ] ------ (f) + vss In the center position, pins (b) and (e) are unconnected. In the up position, pin (b) is connected to +vss while pin (e) is connected to -gnd. In the down position, pin (b) is connected to -gnd while pin (e) is connected to +vss. With this setup you can send a Tri-state signal over two wires with a single switch. The next trick is decoding the Tri-state signal back to two common ground pins for the relay which is where the diodes come in. The common ground of the relay is connected to (b) and (e) at the other end of the ethernet cable through two diodes like: (b)--------------(e) Then the forward pin of the relay gets a single diode. (b)-------|>--------(forward) Same for reverse (e)-------|>--------(reverse) Put that circuit into LT-Spice and it decodes the tri-state signal nicely. I don't know if the relay coils have flyback diodes built in but those are also necessary whenever a coil is de-energized it wants to stay on due to the magnetic field and will cause voltage spikes when turned off. The flyback diode "eats" the reverse current when the coil is de-energized and otherwise does not interfere with normal operation.

[@lukekamrath8795]

@@fookingsog In his schematic @2:04 the motors are isolated from the ethernet cable and video by the relays, they have their own power circuit and battery. The back EMF would not be present in the cable.

[@Bill-v650]

probably just needs some 1uF snubber caps on the switches and if those relays are induction and not SSRs some flyback diodes on there and that would kill the video interference.

@@johnbeauvais3159 Yeah, similar physics with pop bottles, a 2-liter soda bottle with its thin plastic walls will hold about 195 psi, but if you upscale it to larger sizes it won't hold it any longer due to pressure vessel physics equation being relative to the radius (can be thought of as shear stress in wall on two sides equal to the center volume of air forcing and trying to rip them from pressureXarea). Even without buckling effects (which does make it worse), its indeed going to scale poorly due to several physics effects like the one you mentioned on top of pressure vessel physics.

[@AsymptoteInverse]

This is good inspiration for a project I've had marinating in my brain for a couple years now. The original plan was to build a sort of bathysphere out of steel pipe, just containing power and whatever electronics were required for lights, sensors, video, etc. It wouldn't be controllable, obviously, but since my interest is just having a look at lake bottoms or maybe the seafloor, it wouldn't really need to be, and it'd be cheap. The Ethernet cable is a great idea, since I hadn't figured out how to get live video from the thing. And the PVC's a lot cheaper than iron pipe. If I fill it with mineral oil and evacuate all the air bubbles, theoretically, I should be able to go to almost unlimited depth. It remains to be seen if my attention span will stay in one place long enough to actually get it done, though...

[@123qwe321ify]

Wont the pressure just force the oil back up at a certain depth ?

[@blak4831]

@@123qwe321ify eventually probably, but as long as the seal is stronger than the hull it’ll go pretty deep, since the hull won’t be able to buckle with incompressible fluid inside. Even a watertight hull filled with air can buckle before the seals pop, which compromises the hull strength and can lead to leaks at a much lower depth

This is what they based the Titan submarine on

[@pseudotasuki]

Sam's shirt was particularly appropriate when he came up with that method to grab the shopping cart.

[@dpidcoe]

Incorporating a pair of cheap microcontrollers (there are plenty of arduino knockoffs for less than $10) would make it significantly better with few changes: - Microcontroller at the control box to monitor the button presses - Button presses are converted to a single byte by the microcontroller, with each bit representing on/off for one of the motors - Single byte is sent down the ethernet cable using a single pair of wires and a protocol like RS485 (you may need some RS232RS485 converter chips, they're a few cents) at a rate of ~50-100hz - Byte is received by microcontroller onboard the sub, at which point that microcontroller interprets it and toggles the motor relays accordingly This means you only need two wires in the tether for your motor control, and if your camera is just a ground and a data line (remember, RS485 is a differential pair so you have no ground from it), you could drop from an ethernet cable to a 4 conductor phone cable, making your tether lighter and cheaper. You'd also greatly reduce the camera flickering when you toggle the relays.

Video flicker was caused by voltage induced pull-down when switching motors.
