I’m partway through a long build of one of the original Kickstarter units (v2.3 I think). Part of the reason for such a long build is my particular requirement for regular 70-100m deep dives (I’m a technical SCUBA diver and much less than this I’ll just dive it!) - other reasons are not having enough time and too many other projects. Having found the acrylic endcaps I assembled to have several issues (I believe now fixed in later versions) I eventually got around to getting aluminium endcaps machined and anodised.
I have a pressure pot and was able to test the resulting (empty) pressure housing well beyond its rating to 140m - and at this depth the cylinder imploded rather impressively, shattering into literally100 scarily small pieces with a VERY loud bang. Luckily the endcaps survived and I have another tube on the way. I had contacted the openROV team who suggested others on here may be interested.
If anybody does want anything tested in the pot, then feel free to get in touch (it’s about 300mm/12" inside diameter, about 1m/3ft long, and will go to 200m water depth if I change the gauge on it). An OpenROV should just fit. Only thing is that I and it are in Australia…
