    Now, we don't normally cover this sort of networking equipment, but we were quite impressed by HP's new t410 All-in-One Smart Zero Client after we spoke to its proud product manager Walt Jurek. First of all, this isn't an AIO desktop PC, nor is it an LCD monitor -- well, if you're unfamiliar with thin clients, just think of this as an 18.5-inch, 1,366 x 768 LED-backlit monitor (featuring a 3M technology for the 200 nit brightness -- our money's on the Uniformity Tape) that uses just one Ethernet cable to get both its 13W power from a PoE (Power over Ethernet) switch, as well as data connection over Citrix, Microsoft or VMWare protocol. The t410 can automatically detect the virtualization environment and then reprogram its digital signal processor when needed, meaning less manual work for the admin (in theory, anyway). More after the break.

  • Arduino delivers Android and Ethernet toys for all the good little DIYers

    It's like Christmas in July Arduino fans. The Italian open-source hardware platform just scored a number of new add-ons and a pair of fresh iterations that are sure to keep you tinkering and hacking for some time. First up is the Arduino Ethernet -- which, as you may have guessed -- sports an onboard Ethernet jack. You'll probably want to pick up a USB Serial Adapter to program the ATmega328 chip but, once you've loaded your code, it can be hooked up to the web without the need for a Ethernet shield -- and an optional PoE (Power over Ethernet) module means you'll only need one cable for all you net-connected projects. The DIY scene's favorite microcontroller was also blessed with the new Arduino ADK board, a take on Google's accessory development platform. And, if you're not sure where to get started, you can pick up an entire kit for €249 (about $352) that includes not only the ADK board, but a huge pile of sensors and components, and the Mega Sensor Shield to arrange them on. The ADK alone will run you €59 ($83), while the Arduino Ethernet costs €39.90 ($56) with an additional €14.90 ($21) for the PoE module. Can you say a synonym for awesome?

  • CradlePoint introduces pair of 4G routers, one for home, one for the road

    We're in Vegas this week, enjoying the sights and sounds of Sin City -- and the 4G wireless. Blistering city-wide wireless is great, but everyone having to have their own USB adapters isn't so much fun. If only we had one of the new 4G routers that CradlePoint is launching this week. The first, a portable model, can beam WiMAX out again as an 802.11n signal to up to 16 people, sporting VPN, WEP, and WPA security. Should you go out of 4G range (not hard to do) there's a USB port through which you can connect a 3G modem, and four hours of battery life should get you through the most grande of lattes if you can't find an open plug at the coffee shop. For the wired lifestyle there's the CBA750, adding a WAN port and four LAN ports to the mix, ditching the battery, and taking its power exclusively over Ethernet. That's convenience. The CBA750 is available right now for $249, and we expect the portable version to go for the same price whenever it hits the Strip.

  • Power over Ethernet kit for Airport Extreme Base Station

    Back in the day, the white dome Airport Base Station supported Power over Ethernet, which allowed the station to be mounted far away from an outlet (e.g. on a ceiling) powered by just the ethernet data cable, great for preexisting buildings where running power for base stations might be expensive or impossible.The most recent Airport Extreme Base Stations have lacked this convenient feature, but MacWireless is now offering a PoE kit that works with the 802.11n AEBS. The $59.98 kit contains both an injector that plugs into the outlet and a splitter for the other end that goes to the AEBS, allowing both data and power to be sent over a single Cat5 cable up to 330 ft long. A shorter 200 ft range kit is $39.98.[via MacNN]

  • En-Twyn's En-Compass incorporates Powerline into socket

    CeBIT and Powerline seem to have a thing for one another, and sure enough, this year we're seeing yet another firm storm onto the scene in an attempt to advance the flagging technology. London-based En-Twyn set up shop in Germany to showcase its En-Compass, which doesn't require any special wall cutouts and differs from most other Powerline systems by packing its electronics on the backside. In other words, you won't have any unsightly adapters protruding from the front. Beyond that, everything else works as expected -- Ethernet signals travel over your existing home wiring setup -- but unfortunately, the product is still stuck in prototype stage at the moment.

  • Asus and Planex unveil snazzy new WAPs

    With all this 802.11n hubbub going on, it's refreshing to see a trio of new 802.11b/g wireless access points that have set out to make the WiFi goodness we're used to even better. Planex Communication's GW-AP54SP-P (pictured after the jump) is a two-port WAP that supports automatic power-on functionality when detecting wireless activity, bridge / repeater capability, WPA2 support, and of course, up to 54Mbps transfer speeds. Meanwhile, Asus' latest power duo -- the WL-320gE and WL-320gP -- reportedly provide "up to 850 meters" of open space coverage thanks to their 5dBi high-gain antennas; they also sport SNMP to allow system administrators to manage multiple APs from remote locations, and somehow managed to pass the FCC's oh-so-restrictive transmission guidelines as well. The WL-320gP goes one step further by incorporating power over ethernet (compliant with 802.3af) to "eliminate the hassle of locating a power source." While pricing and release date information wasn't readily available, it's probably safe to assume these WAPs won't demand the same premium as those 802.11n-compatible alternatives -- and at least this trio operates on a standardized protocol, eh?Read - Planex Communication's GW-AP54SP-P Read - Asus' WL-320gE / WL-320gP
