As I mentioned in the gift thread a few weeks ago. I was fortunate enough to receive an OpenROV 2.8 kit for Christmas and wanted to document the process on the boards.
It is a fully contained submersible drone that can be controlled by a Xbox controller, can descend up to 300 feet, and streams live video back to your laptop. I've never been interested in an aerial drone, but when I saw this a few years ago, I put it on my wish-list. The OpenROV guys have a pre-built model coming out in late 2017, the Trident, but I wanted to build my own.
For those of you who don't care about the build process. This is what it looks like. I promise I'll have something similar to show you as well.

Laser-cut acrylic pieces ready for assembly.
Arranging the acrylic pieces for the main body structure.
First time ever using acrylic cement. I was certain that one of the local hobby shops would have this so I called around to a few. I may as well have been asking if they had meth in stock for the way these people responded. I ended up ordering it on Amazon. It has special shipping restrictions so it took a few weeks to get here.
I used Weld-On 4 which is a water thin version. https://www.amazon.com/Weld-Acrylic-Adhesive-Applicator-Bottle/dp/B0096TWKCW
Acrylic cement is a solvent that basically welds two pieces of acrylic together by softening the material and then fusing them as it evaporates. It is fantastic from a strength standpoint and once you get the hang of it, fairly easy to apply. Unlike super glue, if you spill a little extra on the face of one of your pieces, you aren't going to get an ugly pile of dried glue, the cement will evaporate away. The capillary effect is a big help as it effectively pulls the cement into the butted joint.

I need more bench vises. This was my creative solution at supporting the camera mount while I cemented the camera supports.
Cementing the skeleton of the ROV together.
Finished camera mount and ROV skeleton.
Time to build the electronics assembly.
Cementing the electronic mount end-cap
Pieces for the battery tube end-caps and a thruster/mount
As you'll notice throughout the build. It calls for creative uses of unrelated parts. In this instance, you use the thruster shaft to align the battery tube end-caps properly. These are supremely important as they are all that stands between your Lithium-Ion batteries and the crushing depths.
