Re: Rov Reboot (3d Printed)
Wow!!!!Really nice construction
Re: Rov Reboot (3d Printed)
Yeah the end result turned out really nice, good job!

Re: Rov Reboot (3d Printed)
there is deffo oring compression there! possibly a little too much?
how hard are the orings you've selected?

Re: Rov Reboot (3d Printed)
Yeah it probably is too much, I can't even get the end cap off now. They are silicone O-rings and listed as "Durometer is A70". At this point as long as it's sealed I don't care. I'll cut the grooves deeper on the next one.

Re: Rov Reboot (3d Printed)
The frame sides where printed in some cheap Chinese filament which I didn't properly configure so they came out kind of rough. To get ready for paint I coated them with spot glazing putty and then sand most of it off to smooth things out. Here you can see one coated and the other sanded they are not perfect but good enough for the prototype.
Now it's on to the painting process.....

The Basic Rov Control System Wiring Manual.
A few pictures before some quick lake trials.
Ready for the float test... (I was crossing my fingers here)
Well it floats.... that's a good start.

Here is some video of the first control tests... it's not very exciting but it looks like it going to work out. It's not balanced correctly yet I still have to add the camera pod and mini manipulator I designed for it so it's pushing the nose up right now. It actually might be a little to fast for just on/off control though so I might have to add a speed control up top to limit the power to the thruster. I'll figure that much out when I get to it.
Hopefully it's not another couple years before the next update.

It's been a long time since I've worked on this but I'm trying to get back into it. Something happened to my control system since the last time I tested everything and I couldn't get it to work right so instead of wasting time tearing the old one apart I just decided to redo it from scratch. I started by designing a new projects box and then 3D printed it in PETG so it would withstand the heat of the wax waterproofing process.
I used four of the H-bridge relays I use on the Seafox just because I know they can handle the amps of the bilge pumps. (I'm not sure if one of the relays I used last time crapped out or what... it worked when I put it away.) The projects box was designed to hold these four relays securely in the center.
It's not my cleanest solder work as I rushed everything just to get going again. I added quick disconnects to the thruster too just encase I had to redo it again in the future I could easily just swap it out. I didn't take any pictures of the wax poring process as I've gone over that before in the https://www.youtube.com/watch?v=yOj77rxLPmE

Re: Rov Reboot (3d Printed)
It looks realy nice and very fast indeed.

Re: Rov Reboot (3d Printed)
Next I have to machine out some recesses on the one end cap and drill some holes for the through connectors for the 5 wires. After that I will have to re-test in back in the chamber before installing the actual camera. Overall things are going well and it feels great to be making progress on this project again.
