Homebuilt ROVs Forum

Neat built. How do you drill holes in plastic at an angle like that? Drill press + modified lip on the drill bit? Noting special, I just drilled the 1/2 holes (starting with a smaller bit working up) with my hand drill at about a 45 degree angle, perpendicular to the reducing flange. This left behi...

Here's a quick video of the trusters I put together for my build.

Below are some pictures of my custom LED design. I had quite a few super bright white 5mm LEDs lying around and designed a simple circuit board for them which fits snuggly in 1" PVC. The bottom photo shows how I extended the leads through (and soldered to) an identical PCB to give the fixture a...
