Remote Operated Underwater Vehicle

PVC hull, SLA batteries, Bilge Pumps, sounds like a good start to [Jimmy’s] ROV project. Paintball gun (as a BCD), dual live cameras paired with an Arduino making it internet controlled, all tethered with a fiber optic cable, sounds like [Jimmy’s] ROV got a whole lot more astounding.

While some very important parts have yet to be implemented, like the leak detectors, the project looks to be going quite smoothly. With updates promised, we can’t wait to watch this continue until the end.

Installing A Starscape Ceiling

October 8, 2009 by Mike Szczys 33 Comments

[Mike Galloway] set out to install a lighted starscape in the ceiling of the baby room. We remember first coming across this type of thing at a Planet Hollywood restaurant at least 10 years ago. We’ve always wondered how difficult this type of thing is to install.

This setup involves an LED based illuminator and bundles of fiber optics. [Mike] first mounted the illuminator in the corner of the room at ceiling level and ran the bundles of fiber optics up into the attic. He then used a cordless dremel to drill 1/16″ holes, one for each fiber in the bundle. This translates to a lot of holes! Once everything was in place, he filled the holes with glue to hold the fibers in place, and snipped off the excess from the room-side using a fingernail clipper. We’ve embedded his video of the system in action after the break.

This may take some time, but it seems easy enough and now we know how these ceilings work.

Communication Anachronism

anachronism

There aren’t many details, or really any at all here. This was just too fun not to post. Here are two cans strung together, just like when you were a kid. However, when you talk into one the sound is then converted and transmitted to the other via fiber optic cable. Looking at the pictures, it seems that it is only one way though.
