Top five power-line adapters: When Wi-Fi fails you

In home networking, the fastest way -- in terms of data speed -- to connect devices together is via network cables. However, running cables properly, which involves making networking ports and connector heads, is no easy task. This is part of the reason the wireless network (Wi-Fi) has become so popular. But chances are, there's a spot in your home that the Wi-Fi signal can't reach, because of distance or thick walls. This is when a power-line connection can be a useful alternative.

Power-line adapters basically turn the electrical wiring of a home into network cables for a computer network. You need at least two power-line adapters to form the first power-line connection. The first adapter is connected to the router and the second to the Ethernet-ready device at the far end. There are some routers on the market, such as the D-Link DHP-1320, that have built-in support for power-line connectivity, meaning you can skip the first adapter. After the first connection, you just need one more adapter to add another Ethernet-ready device to the home network.

Apart from the ability to bridge the network through thick walls, power-line connections are also a lot more stable than Wi-Fi signal and have as low latency and a regular Ethernet wired connections.

Currently there are two main standards for power-line networking, HomePlug AV and Powerline AV 500. They offer speed caps of 200Mbps and 500Mbps, respectively. The following is the list of top five power-line adapters on the market. This list is sorted by the review date, starting with the most recently reviewed. It will be updated as more devices are reviewed.… Read more

Get a 3-in-1 sync/charge cable for $6.99

Someday, all syncing and charging will be done wirelessly. (The syncing is pretty much there, actually.) Until then, we remain slaves to cables.

Printing images with fire

If you have some random bits of wood floating around that you just don't know what to do with, perhaps you could take a leaf out of Lucien Langton's book. The 25-year-old student at the Lausanne University of Art and Design (ECAL) in France has built a functioning printer for wood that uses fire as a medium.

FireWriter consists of a repurposed inkjet printer controlled with Arduino Uno, a calibration module equipped with an optical sensor and fitted with a Dremel torch loaded with a mixture of butane and propane that burns at up to 1200 degrees Celsius.

A black-and-white image has to be fed into Processing software; it then creates a Wiring script that's fed back to the Arduino unit. … Read more

Shred your e-mails with a typing guitar

Having already conquered the complex process of separating the cream from an Oreo cookie, physicist David Neevel has turned his inventive eye to the issue of typing on a computer while shredding on a guitar.

Neevel connected together a Flying V guitar, an Arduino, a custom relay board, and a Roland GR-33 guitar synthesizer to turn the notes played on a guitar into a working keyboard recognized by his laptop as a typing input device. The Email Guitar lets the user rock out while getting work done.… Read more
