Fresh hacks every day
If you want to go high bandwidth, fiber optics is the way to go. From trans-oceanic cables to the yet-unseen ‘fiber to every home,’ fiber optics allows a lot more bandwidth than a copper cable. In low-bandwidth applications, fiber optic cable transmits data using one color of light. There’s a way to get more bandwidth out of a fiber optic … Read the rest
[Garrett] over at MaceTech was approached by a friend who needed a light-up mohawk installed on a Viking helmet, and he needed it ASAP.
Now, [Garrett] does tons of work with LEDs but it’s not every day you are asked to construct a sound-responsive LED mohawk. He had all sorts of LEDs and other bits on hand, but finding … Read the rest
There’s something calming about looking up into the night sky and seeing an array of shining stars off in the distance. [Marou] is a big fan of stargazing, but sometimes conditions are not optimal, so he decided to bring the stars inside.
His idea was to build a ceiling lamp that didn’t bask the room with light, but rather … Read the rest
What do you do with 100 player piano rolls but no player piano? You come up with a way to digitize the information for MIDI playback. The rolls have 90 columns worth of holes, 88 for the keys and two more for pedals. Voids in the paper cause a note or pedal to be played, so an optical sensor … Read the rest
So you manged to get a great deal on a fake tree during the after Christmas sales, but what should you do with your old one? If it was lighted with fiber optics you can reuse the strands to create your own star map. [Mr Trick] shows how to disassemble one of these trees, grouping the fibers by length. … Read the rest
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 … Read the rest
[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] … Read the rest
