These days, if you wire your house with anything less than gigabit, you might end up throttling your Internet connection. If you wired things up using two pairs per device …read more Continue reading Say No To Obsolescence, Wire Up Your House With Fiber
Small is often subjective. For example, a school bus is small compared to an Airbus A380. But other things are just small all on their own and need no comparison …read more Continue reading Miniature Motorized RC Car Is Massively Impressive
Everyone loves LED matrices, and even if you can’t find what you like commercially, it’s pretty easy to make just what you want. Need it big? No problem; just order …read more Continue reading Big LED Matrix Becomes Tiny LED Matrix Thanks to Fiber Optics
A world of information is thrumming through miles of cables laying on the ocean floor. This map will show you where they are. Continue reading This 3D Map of the Undersea Cables Connecting the Globe is Mesmerizing
Fiber optics are a great way to transfer huge quantity of data at lightning speed. Thanks to the property of total internal reflection, which allows light to flow through a glass fiber like fluid through a pipe, they can be used for communications at long distances and form the backbone …read more
In the middle of the East Coast’s slow broil in the summer of 2018, a curious phenomenon surfaced. As a tropical air mass settled in and smothered the metropolitan New York area, a certain breed of stock speculator began feeling the financial heat as the microwave signals linking together various …read more

TRAXyL, a DC-based startup, hopes their patented resin will provide more options for building affordable internet infrastructure. Continue reading Why Bury Broadband Fiber When You Can Just Glue It to the Road?
Many people overlook the fact that the internet relies on vast networks of cables connecting continents under the sea. Continue reading This Is How the Internet Crosses the Ocean
This is the type of crowd that’s famous for building their own test equipment. If you need a way to program a flash chip, don’t go out and buy one — you can just build one. Need a spectrum analyzer? You can build that out of copper clad board. For his Hackaday Prize entry, [oakkar7] is building an optical power meter, capable enough to do futzy fiber work, but still completely DIY.
When you get into networking and telecom connections that don’t begin with the letters ‘RJ’, you start to stumble upon SPF transceivers. These ‘small form factor pluggable’ devices …read more

Most of us have Ethernet in our homes today. The real backbones of the Internet though, use no wires at all. Optical fibers carry pulses of light across the land, under the sea, and if you’re lucky, right to your door. [Sven Brauch] decided to create an optical link. He didn’t have any fiber handy, but air will carry laser pulses over short distances quite nicely. The idea of this project is to directly convert ethernet signals to light pulses. For simplicity’s sake, [Sven] limited the bandwidth to one channel, full-duplex, at 10 Megabits per second (Mbps).
The transmit side …read more
