Re: Simple thruster housing
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...

Re: Power via 48v Tether
Also be careful with the amp ratings on the step-up you posted. The step-down was 10A, but the step-up is only rated for 3A which is less than most single bilge pump motors pull under load. If you are running 3 pumps then 12A+ is not out of the question.

Robot Claw from SparkFun
Has anyone played with one of these? Seems like you can't beat it for the price. I'm going to get one with my next order and see how well it works. <3 Sparkfun.

Re: 1st water test fourth frame design
Could you talk a bit about the previous 3 frame designs and what makes this design better than previous designs?

Re: Computer Fans
It might work for a featherweight design, otherwise I think your going to suffer from a serious lack of torque.

My custom LED lights
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...
