Yeah, the video is a bit out of date- now the ROV plugs directly into a laptop (or any other devise with an Ethernet port) and you can control it directly from that!
Also, I saw on info@openrov that some other parts were missing from your kit. Sorry about that- it seems like what may have happened is that the box was closed prematurely before those last items were added. Anyway, thanks for bearing with us and we'll try to get you some replacement parts right away.
I don't know if the syringes you'll need are sold in stores, but the part number is REF 309628 in case you want to check. They sell large boxes of them on Amazon as well, but I think we'll be able to get some to you before that would arrive.
Anyway, please keep us in the loop with how the rest of the build goes. I'm REALLY anxious to see what the potting looks like with the hardware store epoxy. Send some photos! Also, let us know if you do any pressure testing. If this works well, it could save people a lot of time and money compared to the stuff we've been using.
Thanks for the feedback,
