How to Check Seismic Vibration Sensors
Hi,
I wonder if there is a device for checking the characteristics of seismic vibration sensors just like Tk-3 of Bently Nevada is used for checking that of eddy current transducers. There must be a device for that but I do not know if there is.
I actually want to

Guitar Hero Played On Side of House in Christmas Lights Invents New Class of Neighborhood Competition [Guitar Hero]
This isn't the first time Christmas lights have met Guitar Hero on the pages of Gizmodo, but this former Disney employee's efforts are definitely the best use of the game that I've ever seen.
Using 21,268 lights and LEDs, ex-Disney imagineer and special effects specialist Ric Turner turned the front of his house into the perfect setting for a Guitar Hero Christmas lights spectacular.
As he explains:
Christmas Light Hero is using 7 light controllers from Light-O-Rama built from kits to control 21,268 lights and LEDs. Each controller has 16 outputs and 2-3 TTL level control inputs that are used by the game system to fire different programmed light sequences depending on what happens in the game. It relies on the fact that the game sequence is very consistent. If the game and the lighting sequences start together, they will stay in very good sync through the length of the song. The light program allows branching and overlays for fail, star power and "ready." I have some ideas to automate the initial show/game sync, but for now you have to push doorbell buttons at the right moments.
Rubberneckers watching in their cars can tune into the frequency 99.1 to hear the audio, or even partake in the fun if they dare. [YouTube via MAKE via Geekologie]
For a Post-Christmas Treat, Order a Looky-Likey Android From Japan [Robots]
What would you spend $225,000 on? An animated android, styled after yourself? Starting in January the Japanese store Sogo & Seibu will begin taking pre-orders for these "Actroids." They may not walk, but they can move their upper bodies.
Kokoro, the company which brought us those HRP-4C female androids back in 2005, will make these Actroids for Sogo & Seibu. Customers can record audio so the robots not only look like them but also sound like them, and "she also does the best work as a guide with her out-standing eye-catch effect!" Careful you don't fall for her eye-catch effect too hard, now. [Sankei News via PlasticPals and CrunchGear]

Google Nexus One Phone Gets FCC Detailing [Nexusone]
Less than 24 hours after Google employees were gifted Nexus One Google phones, and started twitpic-ing them, the handset has turned up on FCC's site with a few of the specs detailed.
With the model number PB99100, the HTC-built "NEXUSONE" (as it's listed) is apparently quad-band GSM/GPRS/EDGE, as we heard yesterday, with UMTS/HSUPA on the 850/1700/1900 frequencies, according to the FCC-digging Engadget. This means that the Nexus One will be capable of 2Mbps upload speeds and 7.2Mbps download speeds.
Other specs discovered amongst the FCC jargon include a microSD card slot, 802.11b/g Wi-Fi and Bluetooth 2.1. Got any more details for us? Hit us up on tips@gizmodo.com now. [Engadget]
To Create Jobs, Stop Destroying Jobs
With unemployment stuck around 10 percent, President Obama has pledged "to take every responsible step to accelerate the pace of job growth." Here's a thought: Instead of trying to "create" jobs by tweaking this tax break or increasing that spending program, why not stop doing things that destroy jobs?
The author of that incredibly sensible view, Charles Lange of the Washington Post editorial staff, suggests three specifics:
End federal protectionism and price supports for sugar.
Repeal the Davis-Bacon Act. ... This law requires employers to pay the "prevailing" local wage on federally funded projects.
Reduce the federal minimum wage.
And if we start thinking this way, we can find other good examples. For example, we could eliminate professional licensure in medicine, law, and other occupations.

No Point Hiding Your Tattoos Now Crims, as Scientists Can See Right Through Them [Infrared]
And you thought turning your "terrorism 4 eva" tattoo into "terrariums 4 eva" would stop you getting caught. Scientists are working on a new infrared camera that can detect adapted tattoos, which will help recognize crafty criminals.
Supposedly if the tattoo has changed, either by laser removal, adding more ink or even surgery, the infrared cameras can pick up on the change, and actually illustrate what the original design once looked like. It'd prove invaluable for detectives seeking criminals who may've tried disguising themselves, though reports of cameras detecting wigs and fake mustaches are still sadly unfounded. [TechRadar]
HTC Legend Creeps Out Again, Looks Even More Like The Hero Than We First Thought [Android]
That HTC Legend handset from the leaked roadmap we saw the other week has just been given another airing in public, with the Hero-esque aesthetics and specs revealed. LED flash, anyone?
Part of the "Lifestyle" range of phones HTC is cooking up, the Legend will contain a Qualcomm MSM7227 processor, which was revealed earlier this year for budget (sub-$150) smartphones. It'll be fast, but it's no Snapdragon, with the CPU clocking in at 600MHz. Internal memory is listed at 512MB with 256MB RAM, and the battery is a 1300 mAh floozy—again, nothing special, with the Hero having a 1500 mAh battery.
A 3.2-inch HVGA AMOLED capacitive touchscreen, 5.0-megapixel camera with autofocus and LED flash (a one-up on the Hero, there), microSD slot, Bluetooth 2.1, GPS, G-sensor, digital compass, 3.5mm headphone jack and microUSB port round the Legend off nicely, but it's only the addition of an optical trackpad and LED flash which are the main differences between this and the Hero. Supposedly it'll launch in March according to Ai.rs, and the leaked roadmap of launches. I've still got one more question for HTC—will the bottom of the chin actually be red or green? [Ai.rs]

A splash of colour
Stunning male Bluethroat on Brownsman in mid-May 
As rare as they come - a Black-headed Bunting in mid-September
A rarity on the Farnes - a Moorhen with Puffins!
Eastern promise - a summer-plumage Red-throated Pipit
Your can't see me - a Barred Warbler on Staple Island
Five Yellow-browed Warblers graced the islands this year
Monday 14th December comments:
The festive period is upon us and to continue the overview of the season, I though I'd bring you a splash of colour with some of the bird highlights of the year. It was another good year for the range of migrants which were recorded on the Farne Islands, as 178 were recorded with the outer group edging the inner group by 159 to 158 for the total number of species seen. Without doubt, three stunning highlights captured the headlines, as the islands boasted only their second ever (and twelfth English) record of Lanceolated Warbler in late September, with fifth Fea’s Petrel and Black-headed Bunting, all three worthy contenders for ‘bird of the year’.

Although spring passage was disappointing compared with the previous season’s impressive showing, the islands produced their sixth and seventh Red-throated Pipits, both on Brownsman in late April and mid-May respectively. As well as the outstanding rarities, other birds of note included Spoonbill, Balearic Shearwater (2), Cory’s Shearwater (3), Leaches Petrel, Storm Petrel (10), Garganey, Osprey, Marsh Harrier (3), Hen Harrier, Quail (2),Wood Sandpiper, Spotted Redshank, Grey Phalarope, Glaucous Gull, Iceland Gull, Mediterranean Gull (4), Sabine’s Gull, Long-eared Owl, Wryneck, Cuckoo (3), ‘Blue-headed’ Wagtail (2), Richard’s Pipit (2), Bluethroat (2), Barred Warbler, Icterine Warbler, Yellow-browed Warbler (5), Red-breasted Flycatcher (2), Firecrest (4), Red-backed Shrike, Hooded Crow, Common Rosefinch, Common Redpoll, Crossbill (6) and Ortolan Bunting. I'm sure a lot of east coast locations would be proud of such a list!
WISE Ready to Soar Into Space

+ Larger view
All systems are "Go" for the Monday morning launch attempt of NASA'S Wide-field Infrared Survey Explorer (WISE) from Vandenberg Air Force Base in California. The weather forecast calls for 80-percent favorable conditions at launch time. A tower around the rocket that will boost WISE to space was rolled back tonight. WISE is safely tucked inside the rocket's nose cone.
The launch window opens at 6:09:33 a.m. PST (9:09:33 a.m. EST). The WISE space telescope will scan the whole sky in infrared light, uncovering hidden cosmic objects, like the coolest stars, dark asteroids and the most luminous galaxies.
More information is online at http://www.nasa.gov/wise and http://wise.astro.ucla.edu and http://jpl.nasa.gov/wise.
